The document provides guidelines for preventing injuries during gynecological laparoscopic procedures. It discusses that approximately 250,000 women undergo laparoscopic surgery in the UK each year, with serious complications occurring in about 1 in 1,000 cases, frequently during insertion of trocars. The guideline aims to highlight strategies to reduce these complications. It reviews evidence on different entry techniques, risks, and rates of complications. It provides recommendations on safe surgical techniques, including using the appropriate entry technique, achieving adequate intra-abdominal pressure before trocar insertion, and checking for adherent bowel after entry. Surgeons should have proper training and experience to perform laparoscopic procedures safely.

Robotic hysterectomy: A review of indications, technique, outcome, and compli...Apollo Hospitals
Hysterectomy is the second most common surgery performed on women after cesarean section. The advantages of minimally invasive hysterectomy such as reduced hospitalization, quick recovery with more rapid return to normal activities, and less postoperative morbidity are well known. Although most guidelines recommend that minimally invasive hysterectomy should be the standard of care, the gynecologists have been slow in adopting minimally invasive laparoscopic techniques to perform this operation. Since its approval in 2005 for gynecological surgeries, robot-assisted hysterectomy has been found to be feasible and safe both in benign and malignant indications. This significant difference is mainly due to ergonomics, endowrist movements of instruments, and stereoscopic three-dimensional magnified vision. The specific indications for hysterectomy where the robotic technology can benefit women are the ones with adhesions such as severe endometriosis, large uterus with large or multiple fibroids, early carcinoma cervix, and/or endometrial carcinoma. However the main benefit of this procedure was seen in the reduction of open surgery including conversions during laparoscopic hysterectomies. In the long run, we need to critically examine the long-term benefits and appropriate indications for robot-assisted hysterectomy especially in benign conditions, thus reducing the incidence of open surgery in gynecology. This review describes the operative procedure of robotic hysterectomy in eight steps.

LAPAROSCOPIC VERSUS OPEN APPENDICECTOMY IN ADULTS. (STUDY OF 50 CASES)KETAN VAGHOLKAR
Background: Appendicectomy is one of the common procedures performed by a general surgeon. However,
the advent of laparoscopic appendicectomy has reduced the number of open appendicectomies performed. Therefore
there is a need to study the advantages of the laparoscopic approach over the traditional open approach. Aims: The
study aimed to compare laparoscopic appendicectomy with open appendicectomy based on various intraoperative and
postoperative parameters Materials and methods: 50 patients undergoing interval appendicectomy were randomised
into two groups. Group A comprised 25 patients who underwent laparoscopic appendicectomy and group B comprised
25 patients who underwent open appendicectomy. Results: Confirmation of diagnosis and evaluation of intraoperative
findings was easier in group A patients. In addition, early commencement of feeds with early bowel movements, reduced
need for postoperative analgesia due to less pain, lesser complications and shorter duration of hospital stay was observed
in group A patients. Conclusion: Laparoscopic appendicectomy has better outcomes rendering it a preferable procedure
for appendicectomy.

Nursing Practice Problem
Doctors use urinary catheters to empty urine from patients who have impaired urinary system. Such patients might suffer from kidney failure due to pressure exerted on their kidneys, this is dangerous and can permanently damage their kidneys. The Urinary catheters, however, may cause potential complications on the patients. Research carried on BMC Urology shows that most patients end up suffering from urinary tract infections (UTI) after the use of indwelling urinary catheters. Other complications such as kidney damage, injury to the urethra, bladder stones, and blood in the urine, septicemia and allergic reactions may arise from the usage of the urinary catheter (Feneley, Hopley, & Wells., 2015).
Picot Statement
Prognosis/Prediction: For pediatric patients 65 years and older (P), how does the use of catheters for much longer time (I) compared to the use of indwelling catheters for shorter time(C) influence the risk of Catheter-associated urinary infections(O) during the first ten weeks of indwelling catheter usage(T)?
Most patients who are placed in indwelling catheters for more than the expected time have had the risk of developing urinary tract infections, allergic reactions and others experience challenges in their kidneys.
What are some of the practical methods used to ensure that catheter-related diseases are reduced?
This study aims to make sure that indwelling urethral catheters (IDC) are carried out in a manner that minimizes risks to infection and trauma (Conway & Larson, 2011).

Ureteral injury is one of the most serious complications of gynecologic surgery. Ureteral injury during laparoscopic surgery has become more common as a result of the increased number of laparoscopic hysterectomies and retroperitoneal procedures that are being performed.
There are several risks associated with poor colorectal lesion localization, the most significant being wrong site surgery. Endoscopic tattooing can help mitigate these risks with an easy, fast method for the gastroenterologist to employ and a clear, precise marker for the surgeon to visualize.
Methods: Retrospectively, the file records of the patients who underwent sleeve gastrectomy were examined. Demographic features, Body Mass Index (BMI), the mouth opening, Mallampati score, thyromental distance, sternomental distance, neck circumference measurements and videolaryngoscopic examination results were recorded Results: In a total of 140 consecutive patients (58 male, 82 female) were included in the study. The mean age of the study participants was 35.40 ± 9.78 and the mean BMI of the patients was 44.33 ± 7.52 kg/m2
. The mean mouth opening of the patients was 4.82 ± 0.54 cm
and the mean neck circumference was 43.52 ± 4.66 cm. The mean thyromental distance was 8.02 ± 1.00 cm and the mean sternomental distance was16.58 ± 1.53 cm. Difficult intubation was determined in 8 (5.7%) patients. In logistic regression analysis, age (p : 0.446), gender (p : 0.371), BMI (p : 0.947), snoring (p : 0.567), sleep apnea (p : 0.218), mouth opening (p : 0.687), thyromental distance (p :0.557), sternomental (p : 0.596) and neck circumference (p : 0.838) were not the independent predictors of difficult intubation. However, Mallampati score (p : 0.001) and preoperative direct laryngoscopy findings (p : 0.037) performed in outpatient clinic were the significant
predictors of difficult intubation. Interestingly, all patients with grade 4 laryngoscopy findings had difficult intubation.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)

1. RCOG Green-top Guideline No. 49
1 of 10
PREVENTING ENTRY-RELATED GYNAECOLOGICAL LAPAROSCOPIC INJURIES
This is the first edition of this guideline.
1. Purpose and scope
Approximately 250 000 women undergo laparoscopic surgery in the UK each year.The majority are without
problems but serious complications occur in about one in 1000 cases.Laparoscopic injuries frequently occur
during the blind insertion of needles,trocars and cannulae through the abdominal wall and,hence,the period
of greatest risk is from the start of the procedure until visualisation within the peritoneal cavity has been
established.This guideline aims to highlight strategies to reduce these complications.
2. Background
Over the past 50 years, developments in electronic and optical technologies have meant that it has become
possible to perform many gynaecological operations laparoscopically. The unique feature distinguishing
laparoscopic from open abdominal or vaginal surgery is the need to insert needles, trocars and cannulae for
initial entry into the abdomen.This may result in bowel or vascular injury.There is wide variation in the
techniques used by laparoscopic surgeons and this guideline concentrates the evidence for different entry
techniques.
One of the difficulties of bowel damage associated with laparoscopic surgery is the likelihood that it may not
be immediately recognised and could present some time later, often after discharge from hospital. This
potentially serious complication may require major abdominal reparative surgery and sometimes a temporary
colostomy.1
It is essential, therefore, that women and attending staff understand that the recovery from
laparoscopic procedures is usually rapid and,where this is not the case,that early diagnosis and treatment are
essential and should involve senior medical staff .The relative infrequency of these accidents prevents any
individual laparoscopic surgeon from gaining a true appreciation of their importance or frequency.
3. Incidence of complications
The incidence of complications associated with laparoscopic procedures varies considerably
between reports, depending on the experience of the surgeons and the complexity of operations
undertaken; figures range between 1.0/1000 and 12.5/1000 for all complications. In Finland, 256
complications were reported to the National Patient Insurance Association following 70 607
laparoscopic procedures (3.6/1000). The rate of major complications was 1.4/1000 procedures
comprising intestinal injuries (0.6/1000), urological injuries (0.3/1000) and vascular injuries
0.1/1000).2
Jansen et al. reported the results of a prospective multicentre study of 72 hospitals in
the Netherlands in which there were 145 complications from 25 764 laparoscopies (5.7/1000).3
There were two fatalities and 84 women (3.3/1000) required a laparotomy because of

2. complications.There were 29 cases of gastrointestinal damage (1.13/1000) and 27 lesions of intra-
abdominal vessels (1.05/1000); 57% of the injuries were attributed to problems with laparoscopic
entry.Women with a previous laparotomy were also found to be particularly at risk.
In a French prospective study,the rate of severe complications was 12.5/1000 cases after advanced
laparoscopic surgery.4
This study, which was a snapshot of laparoscopic surgery over a 2-week
period throughout all French hospitals,reported the rate of major complications to be two to three
times higher than in a previous study from France, which reported only complications from
specialised referral centres.5
Although the RCOG instigated a confidential inquiry in the early days of laparoscopy,6
there has not
been a recent national audit of complications of laparoscopic surgery in the UK. A prospective
observational study of all gynaecological laparoscopies performed by all grades of staff during a
calendar year in a teaching hospital reported bowel damage three times in 836 laparoscopies
(3.6/1000).7
In a similar study from a district general hospital of 470 patients operated during a
single calendar year there were two bowel injuries (4.3/1000).8
The bowel injuries in these studies
occurred during procedures for diagnostic or sterilisation purposes where the pressure method
recommended for safe entry in the Middlesbrough Consensus was not employed.9
4. Identification and assessment of evidence
The Cochrane Library (including the Cochrane Database of Systematic Reviews, DARE and EMBASE), HTA,
TRIP, Medline and PubMed (electronic databases) were searched for relevant randomised controlled trials,
systematic reviews and meta-analyses.The search was restricted to articles published in English from 1966 to
January 2006.The databases were searched using the relevant MeSH terms,including all subheadings,and this
was combined with a keyword search. Main keywords included:‘laparoscopic injury’,‘laparoscopic entry’,
‘laparoscopic complications’,‘closed laparoscopy’,‘open laparoscopy’ and ‘direct-entry laparoscopy’.
Additionally, enquires were made with researchers and Council members of the British Society for
Gynaecological Endoscopy (BSGE) and our suggestions were critically appraised at a 1-day study meeting
entitled ‘Avoiding complications of laparoscopic surgery’ held on 7 July 2006 at the University of Surrey
Postgraduate Medical School.
5. Assessment, counselling and consent
How should women be counselled prior to laparoscopic surgery?
Women must be informed of the risks and potential complications associated with laparoscopy. This
should include discussion of the risks of the entry technique used: specifically, injury to the bowel,
urinary tract and major blood vessels, and later complications associated with the entry ports:
specifically, hernia formation.
Surgeons must be aware of the increased risks in women who are obese or significantly underweight
and in those with previous midline abdominal incisions, peritonitis or inflammatory bowel disease.
These factors should be included in patient counselling where appropriate.
Most laparoscopic procedures in gynaecology are performed electively for benign conditions. The
understanding and acceptance of the risk associated with the procedure may be different from that of women
having procedures for life-threatening conditions.10
Women must be informed of the associated risks with
laparoscopy. Evidence from women undergoing laparoscopy for pelvic pain suggests that they do want to
know all complications.11
Potential complications should be discussed according to the principles of
counselling described in the RCOG Clinical Governance Advice No. 6 Obtaining Valid Consent.

3. 6. Safe surgical techniques and training
How should surgeons be trained in safe laparoscopic techniques?
Surgeons intending to perform laparoscopic surgery should have appropriate training, supervision and
experience.
Surgeons undertaking laparoscopic surgery should be familiar with the equipment, instrumentation
and energy sources they intend to use.
Surgeons undertaking laparoscopic surgery should ensure that nursing staff and surgical assistants are
appropriately trained for the roles they will undertake during the procedure.
The safe practice of any surgical technique lies in effective structured training and supervised practice.The
basic elements of this training are covered in the RCOG core training portfolio (www.rcog.org.uk/index.
asp?PageID=1959).
For surgeons intending a career with a significant gynaecological surgical role, including intermediate level
laparoscopic procedures, the Advanced Training Skills Module (ATSM) on benign gynaecological surgery –
laparoscopy would also be an essential requirement. (www.rcog.org.uk/resources/public/pdf/ATSM_
Benign_gynae_surg_laparoscopy_010807.pdf). For those surgeons intending to undertake even more
complex laparoscopic procedures, this training will need to be supplemented by a process of mentorship,
performing surgery of increasing complexity with the support of an experienced laparoscopic surgeon.
7. Laparoscopic entry techniques
The most effective way to reduce complications of laparoscopic entry is to optimise insertion of
the primary trocar and cannula, although there is controversy as to the safest technique for
achieving this. Gynaecologists have tended to favour the closed or Veress needle entry technique,
whereby the abdominal cavity is insufflated with carbon dioxide gas before introduction of the
primary trocar and cannula.The Royal College of Surgeons of England recommends that the open
(Hasson) approach be used in all circumstances.12
This latter method uses a small incision to enter
the peritoneal cavity under direct vision.
In a meta-analysis of over 350 000 closed laparoscopic procedures, the risk of bowel damage was
0.4/1000 and of major vessel injuries was 0.2/1000.13
It might be anticipated that the open (Hasson)
technique would be less likely to cause major vessel injury than the closed method:if a segment of
adherent bowel were injured, it might be more likely that this would be recognised at the time,
allowing immediate repair. However, a study of 10 840 open procedures found six cases of bowel
damage (0.6/1000), four of which were recognised immediately but, in two of them, the diagnosis
was later and reparative surgery was delayed.14
Hasson reviewed a number of series using the open method and found no cases of major vessel
injury and a rate of bowel injury of only 0.1%.15
The most authoritative comparative review of the
safety of open and closed methods of laparoscopic entry was conducted by the Australian College
of Surgeons,16
which found a higher risk of bowel injury associated with open access (relative risk
2.17; 95% CI 1.57–4.63).The risk of vessel damage was so low in both groups that no statistical
difference was observed.17
Two randomised trials have compared the open and closed entry techniques.A meta-analysis does
not indicate a significant safety advantage to either technique.18-20

4. 7.1 Veress needle (closed) laparoscopic entry technique
How should the closed laparoscopic entry technique be performed?
In most circumstances the primary incision for laparoscopy should be vertical from the base of the
umbilicus (not in the skin below the umbilicus). Care should be taken not to incise so deeply as to enter
the peritoneal cavity.
The Veress needle should be sharp, with a good and tested spring action. A disposable needle is
recommended, as it will fulfil these criteria.
The operating table should be horizontal (not in theTrendelenburg tilt) at the start of the procedure.The
abdomen should be palpated to check for any masses and for the position of the aorta before insertion
of the Veress needle.
The lower abdominal wall should be stabilised in such a way that the Veress needle can be inserted at
right angles to the skin and should be pushed in just sufficiently to penetrate the fascia and the
peritoneum. Two audible clicks are usually heard as these layers are penetrated.
Excessive lateral movement of the needle should be avoided, as this may convert a small needlepoint
injury in the wall of the bowel or vessel into a more complex tear.
A consensus document on safe laparoscopic entry was made in 1999, following an international
meeting of gynaecologists and general surgeons with a special interest in laparoscopic surgery to
critically evaluate the available published evidence on entry techniques.9
In a review by the Council of the Association of Surgeons it was suggested that, after two failed attempts to
insert the Veress needle, either the open Hasson technique or Palmer’s point entry should be used.
A single randomised trial has investigated elevating and not elevating the abdominal wall before
insertion of the Veress needle.The latter was associated with a reduced rate of failed entry.20,21
Several tests have been advocated to check that the tip of the needle is free in the peritoneal cavity
and has not penetrated the omentum or any other organ.There is no evidence that these tests are
100% accurate and, indeed, a recent study evaluated some of these tests and concluded that it is
probably of most value to observe that the initial insufflation pressure is relatively low (less than 8
mmHg) and is flowing freely.22
What intra-abdominal pressure should be achieved to safely insert the primary trocar?
An intra-abdominal pressure of 20–25 mmHg should be used for gas insufflation before inserting the
primary trocar.
The distension pressure should be reduced to 12–15 mmHg once the insertion of the trocars is complete.
This gives adequate distension for operative laparoscopy and allows the anaesthetist to ventilate the
patient safely and effectively.
It is necessary to achieve a pressure of 20–25 mmHg before inserting the trocar, as this results in
increased splinting and allows the trocar to be more easily inserted through the layers of the
abdominal wall.The increased size of the ‘gas bubble’ and this splinting effect has been shown to
be associated with a lower risk of major vessel injury. If a constant force of 3 kg is applied to the
abdominal wall at the umbilicus to an abdominal cavity insufflated to a pressure of 10 mmHg, the
depth under the ‘indented’umbilicus is only 0.6 cm.When the same force is applied to an abdomen

5. distended to 25 mmHg, the depth is 5.6 cm (range 4–8 cm).The mean volume of CO2 required to
reach this pressure was 5.58 litres.23
No adverse effect on circulation or respiratory function was
observed as long as the patient is lying flat.24
It is suggested that all gynaecologists should consider
using the pressure technique ,insufflating the abdomen to 20–25 mmHg before inserting the primary
trocar.Further evidence to support this practice is awaited from randomised controlled trials.
Where should the primary trocar be inserted ?
The primary trocar should be inserted in a controlled manner at 90 degrees to the skin, through the
incision at the thinnest part of the abdominal wall, in the base of the umbilicus. Insertion should be
stopped immediately the trocar is inside the abdominal cavity.
Once the laparoscope has been introduced through the primary cannula, it should be rotated through
360 degrees to check visually for any adherent bowel. If this is present, it should be closely inspected
for any evidence of haemorrhage, damage or retroperitoneal haematoma.
If there is concern that the bowel may be adherent under the umbilicus, the primary trocar site should
be visualised from a secondary port site, preferably with a 5-mm laparoscope.
On completion of the procedure, the laparoscope should be used to check that there has not been a
through-and-through injury of bowel adherent under the umbilicus by visual control during removal.
7.2 Hasson (open) entry technique
How should the open entry technique be performed?
When the Hasson open laparoscopic entry is employed, confirmation that the peritoneum has been
opened should be made by visualising bowel or omentum before inserting the blunt tipped cannula.
The Hasson technique of open laparoscopic entry is an alternative to closed laparoscopy that avoids the use of
sharp instruments after the initial skin incision.It allows the insertion of a blunt-ended trocar under direct vision.
Once the fascial edges are incised,they should be held by a lateral stay suture on either side of the
incision. Once the peritoneum is opened, the fascial sutures are then pulled firmly into the suture
holders on the cannula to produce an airtight seal with the cone of the cannula. Gas is insufflated
directly through the cannula to produce the pneumoperitoneum.The blunt trocar is withdrawn
only after the abdomen is partially distended.At the end of the procedure,the fascial defect should
be closed using the stay sutures (and possibly additional sutures) to minimise the risk of herniation.
8. Alternative entry techniques
What alternative entry techniques are available?
8.1 Direct trocar insertion
Direct trocar insertion is an acceptable alternative trocar insertion method.
This technique was developed to overcome the difficulty associated with grasping the abdominal
wall already distended by the pneumoperitoneum.25
Although in experienced hands it is the most
rapid method of entry and can be safely used if the cases are carefully selected,it is not widely used
within gynaecological practice.Six randomised controlled trials have comparedVeress needle with
direct trocar entry.19,26–30
Meta-analysis does not show any safety disadvantage from using direct

6. entry in terms of major complications. There may be an advantage when considering minor
complications.20
8.2 Alternative entry devices
There are several ingenious devices that have been introduced during the last decade to try to minimise the
risk during primary trocar insertion.These include visual access systems,31
radially expanding trocars32
and
second-generation Endotip® (Karl Storz,Tutlingen, Germany) systems.A number of randomised controlled
trials have demonstrated safety advantage in terms of reduced trocar site bleeding with radially expanding
trocars.20,33–35
Further miniaturisation of optical systems has resulted in the invention of an optical Veress needle
but despite the theoretical advantages of such a device there is no evidence to demonstrate the
superiority of this approach over the conventional Veress needle.36
8.3. Alternative sites for primary trocar or Veress needle insertion
What alternative sites can be safely used for primary trocar or Veress needle insertion?
Palmer’s point is the preferred alternative trocar insertion site, except in cases of previous surgery in
this area or splenomegaly.
The rate of adhesion formation at the umbilicus may be up to 50% following midline laparotomy
and 23% following low transverse incision.37
The umbilicus may not, therefore, be the most
appropriate site for primary trocar insertion following previous abdominal surgery.The most usual
alternative site is in the left upper quadrant, where adhesions rarely form, although even this may
be inappropriate if there had been previous surgery in this area or splenomegaly.The preferred
point of entry is 3 cm below the left costal margin in the mid-clavicular line (Palmer’s point).A small
incision is made and a sharp Veress needle inserted vertically.Testing for correct placement using
the pressure/flow test is performed. CO2 is then instilled to 25 mmHg pressure and a 2–5 mm
endoscope is used to inspect the undersurface of the anterior abdominal wall in the area beneath
the umbilicus. If this is free of adhesions, the trocar and cannulae can be inserted under direct
laparoscopic vision. If there are many adhesions present, it is possible to dissect these free via
secondary ports in the lower left abdomen or an alternative entry site can be selected visually.
Other sites have been tried but, in general, are to be avoided. Suprapubic insertion of the Veress
needle puts the bladder at risk of damage and is associated with the highest rate of failure due to
preperitoneal insufflation of gas.9
Instillation of gas through the uterine fundus with the Veress
needle carries the possibility of introducing infection and can be dangerous if bowel is adherent to
the fundus.Similarly,entry through the posterior fornix could cause serious problems if the woman
was found to have deep infiltrating endometriosis with obliteration of the cul-de-sac and the rectum
adherent to the back of the cervix. A low rectal perforation at this site could be particularly
dangerous and it should only be used when imaging techniques have clearly shown that the
posterior cul-de-sac is free from deep infiltrating endometriosis and adherent bowel.
9. Secondary ports
How should secondary ports be inserted?
Secondary ports must be inserted under direct vision perpendicular to the skin, while maintaining the
pneumoperitoneum at 20–25 mmHg.

7. During insertion of secondary ports, the inferior epigastric vessels should be visualised
laparoscopically to ensure the entry point is away from the vessels.
During insertion of secondary ports, once the tip of the trocar has pierced the peritoneum it should be
angled towards the anterior pelvis under careful visual control until the sharp tip has been removed.
Secondary ports must be removed under direct vision to ensure that any haemorrhage can be observed
and treated, if present.
Before placing the lateral ports,it is essential that the inferior epigastric vessels are visualised from within the
peritoneal cavity by the laparoscope and the entry point of the port is away from these vessels.The deep
epigastric arteries and the venae comitantes running beside them can be visualised just lateral to the lateral
umbilical ligaments (the obliterated hypogastric arteries) in all but the most obese patient.In the woman who
is obese,the incision should be made well lateral to the edge of the rectus sheath,taking care to avoid injury
to vessels on the pelvic side wall.
It is recommended that removal of the ports is also under direct vision in order that any haemorrhage
can be observed and treated if present. Any non-midline port over 7 mm and any midline port greater
than 10 mm requires formal deep sheath closure to avoid the occurrence of port site hernia.
10. The woman who is obese
What specific measures are required for laparoscopic surgery in the obese woman?
The open (Hasson) technique or entry at Palmer’s point are recommended for the primary entry in
women with morbid obesity. If the Veress needle approach is used, particular care must be taken to
ensure that the incision is made right at the base of the umbilicus and the needle inserted vertically into
the peritoneum.
Women who are grossly obese are at a significantly greater risk of complications when undergoing
laparotomy. Laparoscopic surgery may therefore be of particular benefit to these individuals. It is
generally recommended that an open (Hasson) technique should be performed for primary entry
in women who are morbidly obese,although even this technique may be difficult.If aVeress needle
approach is used in the woman who is morbidly obese,it is important to make the vertical incision
as deep as possible in the base of the umbilicus, since this is the area where skin, deep fascia and
parietal peritoneum of the anterior abdominal wall will meet.In this area,there is little opportunity
for the parietal peritoneum to tent away from the Veress needle and allow preperitoneal
insufflation and surgical emphysema.If the needle is inserted vertically,the mean distance from the
lower margin of the umbilicus to the peritoneum is 6 cm (± 3 cm).This allows placement of a
standard length needle even in extremely obese women.38
Insertion at 45 degrees,even from within
the umbilicus, means that the needle has to traverse distances of 11–16 cm, which is too long for
a standard Veress needle.39
11. The woman who is very thin
What specific measures are required for laparoscopic surgery in the woman who is very thin?
The Hasson technique or insertion at Palmer’s point is recommended for the primary entry in women
who are very thin.
Women at highest risk of vascular injury are the young, thin, nulliparous women with well-
developed abdominal musculature; patients with severe anorexia are at particular risk.The aorta

APPENDIX
Clinical guidelines are: ‘systematically developed statements which assist clinicians and patients in
making decisions about appropriate treatment for specific conditions’. Each guideline is systematically
developed using a standardised methodology. Exact details of this process can be found in Clinical
Governance Advice No. 1: Guidance for the Development of RCOG Green-top Guidelines (available on
the RCOG website at www.rcog.org.uk/clingov1).These recommendations are not intended to dictate
an exclusive course of management or treatment.They must be evaluated with reference to individual
patient needs,resources and limitations unique to the institution and variations in local populations.It is
hoped that this process of local ownership will help to incorporate these guidelines into routine
practice.Attention is drawn to areas of clinical uncertainty where further research may be indicated.
The evidence used in this guideline was graded using the scheme below and the recommendations
formulated in a similar fashion with a standardised grading scheme.
The Guidelines review process will commence in May 2011
unless otherwise indicated
DISCLAIMER
The Royal College of Obstetricians and Gynaecologists produces guidelines as an educational aid to good clinical
practice. They present recognised methods and techniques of clinical practice, based on published evidence, for
consideration by obstetricians and gynaecologists and other relevant health professionals. The ultimate judgement
regarding a particular clinical procedure or treatment plan must be made by the doctor or other attendant in the light
of clinical data presented by the patient and the diagnostic and treatment options available.
This means that RCOG Guidelines are unlike protocols or guidelines issued by employers, as they are not intended to
be prescriptive directions defining a single course of management. Departure from the local prescriptive protocols or
guidelines should be fully documented in the patient’s case notes at the time the relevant decision is taken.
