Abstract
This case report describes the diagnosis and management of a large mesenteric cyst in a 55 year old lady who presented with abdominal distension & with mass in the left upper quadrant. Mesenteric cysts are rare, benign, abdominal tumors to which <1000 cases have been reported in the literature. While 40% of cases are incidental findings found either through physical examination or imaging, they can cause non-specific abdominal symptoms including pain, altered bowel habits, nausea/vomiting or anorexia. Less commonly, 10% of cases can present with bowel obstruction, volvulus, torsion or shock. In general, the lack of characteristic clinical and radiological features presents as a diagnostic difficulty.
The mainstay in imaging is computerized tomography (CT). CT identifies and helps aid the decision to pursue a laparoscopic or open laparotomy approach, where complete surgical resection is the ultimate goal. In our patient a CT Abdomen & Pelvis showed a large, loculated cystic mass measuring 30cm in cranio-caudal length and 16cm in the transverse and anterior/posterior diameter. While different approaches have been described in the literature to surgically resect such cysts, our approach was largely reflective of size and adherence to surrounding structures in this case. A laparotomy was performed using an upper mid-line 7 cm incision; 4500cc of fluid was aspirated from the cyst which was found to originate from the small bowel mesentery. A complete resection of the multi-loculated cystic sac was done that included the resection of the middle mesenteric vein. The post-operative period was uneventful. The patient was discharged on post-operative day 2. The Histopathology identified the mass as a multi-loculated peritoneal inclusion-type cyst.
mesenteric cyst is fluid collection between two layers of small bowel mesentery, Mesenteric cysts can be simple or multiple, unilocular or multilocular, and they may contain hemorrhagic, serous, chylous, or infected fluid.
The fluid is serous in ileal and colonic cysts and is chylous in jejunal cysts.
They can range in size from a few millimeters to 40 cm in diameter.

The esophageal duplication cyst is a congenital defect of the digestive tract. It has an estimated prevalence of 0.012%, with higher predominance in males. Although it is a common fi nding in children, diagnosis of an esophageal duplication in adults is rare. Following ileal duplication, esophageal is the second most common duplication of the gastrointestinal tract, representing the 10-15% of all gastrointestinal duplication defects. For esophageal duplication, there are two main variants: cystic and tubular, the latter being the least common. They are usually developed during the third to fifth week of gestation due to failure of the vacuolar coalescence. Duplication cysts are commonly located in the distal third of the esophagus.Treatment should always be surgical, even at the asymptomatic stage
of disease, given the possibility of symptom development and complication appearance. Here we present a case of an adult patient presenting with an esophageal duplication cyst with a brief literature review.

Abstract— Gastrointestinal stromal tumors (GIST) are rare neoplasms of the gastrointestinal system. A case of 40 year old man having tense tender abdomen with obliterated liver dullness and shifting dullness was presented in emergency, it was further investigated on X rays, where pneumoperitoneum was found. This case was then decided to go for Laparatomy after routine investigations to further explore. On exploratory laparatomy, diffuse peritonitis with brown coloured fluid was observed. A 10 x 5 x 7 cm mass was found having an opening communicating with the gut lumen was present around 10 cm from the ligament of treitz. However, no adjacent structures, liver or parietal peritoneum seemed to be involved. Gross examination of the specimen revealed an outward bulging mass, which was centrally necrotic and contained hemorrhagic-necrotic material. On histo-pathological examination, features suggestive of gastrointestinal stromal tumor (GIST) with mixed spindle and epitheoid pattern was seen. Mitoses were slightly increased (<5 /> HPFs) leading to the conclusion of LOW GRADE GIST with tumor free margins of gut (R0 resection). So it was a case of Gastrointestinal stromal tumors (GIST), which is a rare medical presentation. So it was decided to report this case as a rare case presentation.
Laparoscopic Excision of Foregut Duplication Cyst of StomachApollo Hospitals
Retroperitoneal gastric duplication cysts lined by ciliated columnar epithelium are extremely rare lesions and its presentation during adulthood is a diagnostic challenge for treating clinicians. This entity often resembles cystic pancreatic neoplasm, retroperitoneal cystic lesions and sometimes as an adrenal cystic neoplasm. Correct diagnosis on the basis of radiological investigation is difficult and histopathologic analysis. We report a case of gastric duplication cyst in a 16year old girl that mimicked as a retroperitoneal /pancreatic /adrenal cystic lesion and was successfully managed by laparoscopy.
Isolated Splenic Metastases from Rectal Carcinoma Five Years after Surgery: C...semualkaira
Primary splenic tumors and splenic metastases are uncommon, and
metastatic splenic tumors are even rarer [1]. According to reports,
the most common source of splenic metastases include melanoma,
tumors of the breast, lung, ovary, colon, stomach, and pancreas [2-
3]. Splenic metastases after rectal cancer surgery is very rare. This
paper reports a case of a patient with splenic metastases from rectal cancer 5 years after surgery. We discuss the route of metastasis
and treatment of this case.
Introduction
Cutaneous metastases from abdominal malignancies are rare and have been reported in less than 5% of patients [1]. Furthermore, metastases in patients suffering from colorectal neoplasia are even rarer entity. Tan et al, among 2538 of the new cases of colorectal cancer over the period of 6 years, reported only 3 cases (0.1%) with cutaneous deposits [1]. Presentation varies from cutaneous or subcutaneous small nodules, rash or large fungating lesions [1-4]. Inevitably, their presence implies the disease progression, and poor prognosis with the reported survival between 1 to 34 months [2,3,5].
We report a case of an elderly patient who initially was thought to present with a simple skin infection. Subsequently, the patient was diagnosed with the moderately differentiated mucinous adenocarcinoma and required the right hemicolectomy. This case highlights that a high index of suspicion is recommended in an unresolving skin erythema.
Abdominal Wall Endometrioma: A Diagnostic Enigma—A Case Report and Review of ...KETAN VAGHOLKAR
Background. Abdominal wall endometriomas are quite uncommon. They are usually misdiagnosed by both the surgeon and the
gynaecologist. Awareness of the details of this rare condition is therefore essential for prompt diagnosis and adequate treatment.
Introduction. Endometriosis though a condition commonly seen in the pelvic region can also occur at extrapelvic sites giving
rise to a diagnostic dilemma. Abdominal wall endometrioma is one such complex variant of extrapelvic endometriosis with an
incidence of less than 2% following gynaecologic operations. Case Report. A case of abdominal wall endometrioma diagnosed
clinically and treated by wide surgical resection is presented to highlight the importance of clinical evaluation in the diagnosis of
this condition. Discussion. The etiopathogenesis, presentation, investigations, and management are discussed briefly. Conclusion.
Clinical evaluation confirmed by supportive imaging is diagnostic.Wide local excision is the mainstay of treatment.

Abstract
The present investigation was undertaken to evaluate the therapeutic efficacy and safety of Crominex® 3+ (a complex of trivalent chromium, Phyllanthus emblica (Amla) extract and purified Shilajit) in moderately arthritic dogs. Eleven client-owned moderately arthritic dogs in a randomized double-blinded study received placebo or Crominex® 3+ twice daily for a period of 150 days. On a monthly basis, each dog was evaluated for arthritis associated pain (overall pain, pain upon limb manipulation and pain after physical exertion) and a full physical exam (body weight, body temperature and heart rate). At the same time intervals, dogs serum samples were examined for biomarkers of kidney (BUN and creatinine), liver (bilirubin, ALT and AST) and heart and skeletal muscle (CK) functions. Findings of this investigation revealed that dogs receiving Crominex® 3+ (1000 μg chromium, 15 mg Amla extract and 15 mg purified Shilajit per day in two divided doses) exhibited a significant (P< 0.05) reduction in arthritic pain noted as early as after 90 days with a maximum reduction after 150 days of treatment. Pain level remained the same or slightly increased in the dogs receiving placebo. No significant change occurred in physical parameters or serum biomarkers in dogs on placebo or Crominex® 3+, which suggested that Crominex® 3+ was well tolerated by arthritic dogs. In conclusion, Crominex® 3+ significantly (P< 0.05) ameliorated arthritic pain and improved quality of life without causing any untoward effects in moderately arthritic dogs.
Abstract
The objectives of this retrospective study were 1. To determine the effect of three surgical techniques (right flank omentopexy, right flank omentoabomasopexy, and left flank abomasopexy), and 2. To determine the effect of concurrent disease on return to normal milk production. Return to normal milk production occurred in 86.3% of cows diagnosed with LDA. Results suggested that cattle diagnosed with LDA corrected via right flank omentopexy or left flank abomasopexy were significantly more likely to return to normal milk production as compared to those corrected via right flank omentoabomasopexy (p< 0.02). No significant difference in return to normal milk production was noted between surgical techniques for correction of RDA (p=1.000) and right abomasal volvulus (p=0.596). Concurrent disease diagnoses did not affect return to milk production. Reported complications were infrequent (n=11).

Abstract
Salmonella is a causative agent for a wide variety of pathological diseases in humans, cattle, poultry and other farm animals and hence Salmonella infections are a major cause of concern to humans, veterinary animals and to food industry. With characterization of over 2500 Salmonella serovars, the pathogen nearly infects all vertebrates but the severity of infection varies from one serovar to another depending upon their host specificity. Some Salmonella serovars are restricted to one or few hosts while others have a broad host spectrum. Thus the understanding of the mechanisms involving host preference by one serovar over another is very important. As our knowledge about host adaptability will then be instrumental in designing better vaccines. Furthermore, methods involving identification of genetic markers for host specificity will prove to be instrumental in determining virulence factors for other pathogenic bacteria that cause systemic infections.

Abstract
The objective of this investigation was to evaluate the efficacy and safety of purified Shilajit in moderately arthritic dogs. Ten client-owned dogs in a randomized double-blinded study received either a placebo or Shilajit (500 mg) twice daily for a period of five months. Dogs were evaluated each month for physical condition (body weight, body temperature, heart rate, and respiration rate) and pain associated with arthritis (overall pain, pain from limb manipulation, and pain after physical exertion). Serum samples collected from these dogs were examined each month for biomarkers of liver (bilirubin, ALT, and AST), kidney (BUN and creatinine) heart and muscle (creatine kinase) functions. The findings of this study revealed that dogs receiving Shilajit (Group-II) showed a significant (P< 0.05) reduction in pain from limb manipulation by day 60, and overall pain and pain after physical exertion by day 120. Maximum pain reduction, using all three criteria, was observed on day 150. Pain level remained significantly unchanged in dogs receiving the placebo. Dogs in either group showed no significant change (P>0.05) in physical parameters or serum markers, suggesting that Shilajit was well tolerated by moderately arthritic dogs. It was concluded that Shilajit significantly (P< 0.05) reduced pain in osteoarthritic dogs and markedly improved their daily life without any side effects.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

The incidence has been estimated to be 1 in 100,000 in the adult population and 1 in 20,000 in the pediatric population [1-3]. They often present in the first decade of life [5] with a 1:1 male to female preponderancW [1,6]. This case report describes the diagnosis and management of a large mesenteric cyst in a 55 year old lady who presented with abdominal distension & with mass in the left upper quadrant. Mesenteric cysts are rare, benign, abdominal tumors to which <1000 cases have been reported in the literature. While 40% of cases are incidental findings found either through physical examination or imaging, they can cause non-specific abdominal symptoms including pain, altered bowel habits, nausea/vomiting or anorexia. Less commonly, 10% of cases can present with bowel obstruction, volvulus, torsion or shock. In general, the lack of characteristic clinical and radiological features presents as a diagnostic difficulty.

J Case Rep Stud 1(6): 603. doi: 10.15744/2348-9820.1.603The mainstay in imaging is computerized tomography (CT). CT identifies and helps aid the decision to pursue a laparoscopic or open laparotomy approach, where complete surgical resection is the ultimate goal. In our patient a CT Abdomen & Pelvis showed a large, loculated cystic mass measuring 30cm in cranio-caudal length and 16cm in the transverse and anterior/posterior diameter. While different approaches have been described in the literature to surgically resect such cysts, our approach was largely reflective of size and adherence to surrounding structures in this case. A laparotomy was performed using an upper mid-line 7 cm incision; 4500cc of fluid was aspirated from the cyst which was found to originate from the small bowel mesentery. A complete resection of the multi-loculated cystic sac was done that included the resection of the middle mesenteric vein. The post-operative period was uneventful. The patient was discharged on post-operative day 2. The Histopathology identified the mass as a multi-loculated peritoneal inclusion-type cyst.
They were first described during an autopsy in 1507 by an Italian anatomist, Benvenni. These lesions are often asymptomatic and found incidentally via physical examination or imaging, as in our case. 40% of cases are incidental findings with a palpable mass present in more than 50% of cases [3]. Less often they can present with non-specific abdominal symptoms including abdominal pain, anorexia, bowel habit changes, or nausea/vomiting. About 10% of cases can present as acute abdomen due to bowel obstruction, volvulus, and torsion or as shock secondary to bleeding or rupture [2,4,7,8]
Mesenteric cysts can occur in any part of the mesentery from the duodenum to the rectum [5]. They occur more often in the small intestine (66%) than the large intestine (33%) [5,6]. In the large bowel most arise from the right colon and ileum but rarely have been found in the mesentery of the descending colon, sigmoid colon and rectum [3,9]. The lining of mesenteric cysts are comprised of endothelial or mesothelial cells, usually cuboidal or columnar-type cells. They lack smooth muscle and lymphatic spaces (unlike cystic lymphangiomas) [4,6].
Imaging modalities such as ultrasound, computerized tomography (CT) and magnetic resonance imaging (MRI) are used in the diagnosis. However, only surgery can identify the site of origin [9]. Depending on size, laparoscopic approaches have yielded successful complete surgical resections [1,9] The first successful surgical resection was by Tillaux in 1880 and the first successful laparoscopic dissection was performed by Mackenzie in 1993 [2,5].

Our case is a 55 year old lady who presented with a distended abdomen with abdominal mass. The patient initially presented to her General Practitioner (GP) for symptoms of utero-vaginal prolapse. On physical examination her GP palpated a large, smooth and mobile mass in the left upper quadrant. She was referred to the Surgical Assessment Unit at University Hospital Limerick for further investigations. She was asymptomatic (denied abdominal pain, irregular bowel habitus, no weight loss) apart from non-specific symptoms including abdominal fullness, decreased appetite and constipation. Her medical and surgical history was significant for hypothyroidism, utero-vaginal prolapse, and right inguinal hernia repair. Medications consisted of levothyroxine 150 mcg BD.
Her laboratory investigations were normal (FBC, U&E, coagulations, LFTs, CRP <3). Tumor marker CA-125 was also normal. An abdominal/pelvic ultrasound revealed a 21 cm multi-septated cystic mass arising from the left side of the abdomen. Findings were concerning for an ovarian neoplasm. In light of this suspicion she was reviewed by Gynaecology who ruled out an ovarian origin.
An Abdomen CT showed a large, loculated cystic mass measuring 30cm in cranio-caudal length and 16cm in the transverse and anterior-posterior diameter (Figure 1). There was intermittent association with the anterior border of the left kidney, pancreas and spleen; the cyst did not appear to arise from these structures. There was no involvement of ovarian tissue. Radiological impression was that of a large mesenteric cyst. Given her stable presentation, she was discharged and re-admitted for an elective removal of the cystic mass three weeks later. Procedure
The multi-loculated mesenteric cyst was excised electively under general anesthesia. A laparotomy was performed using an upper mid-line incision (7cm wound) (Figure 2). Firstly, 4500cc of fluid was aspirated from the cyst then dissection followed.
The cyst originated from the small bowel mesentery. It was adherent within the small bowel to the left side of the sigmoid colon, and posterior aspect of the left kidney. On the right side it was attached to small intestinal mesentery, posteriorly with aorta and inferior vena cava. Superiorly, it was adherent to the third part of the duodenum. A large dissection was done including middle mesenteric vein. No intra-operative complications were recorded. The patient had a quick recovery and discharged shortly after the procedure (Figure 3).

This case report demonstrates the presentation, diagnosis and surgical management of a large mesenteric cyst which was found incidentally with abdominal distension on physical examination. Mesenteric cysts are rare abdominal tumors that seldom present with overt abdominal symptoms. Abdominal pain is the most common symptom and an abdominal mass is found in more than 50% of cases [3]. Non-specific symptoms such as nausea, vomiting, weight loss, anorexia, weight loss and bloating may not be severe enough for patients to seek medical help. Their diagnosis is important however because they can present with acute symptoms such as hemorrhage, rupture, torsion, volvulus, or local compressive symptoms such as hydronephrosis, intestinal obstruction or lower limb oedema [2,3,7,8] (Figure 4). Discussion
On CT, mesenteric cysts can occur anywhere in the mesentery, from the duodenum to the rectum, and may extend into the retroperitoneum. They appear as cystic lesions that are further characterized by their wall thickness (thick or thin-walled) and their loculation (uni-locular or multi-locular) [10] (Figure 5, 6). Due to their cystic appearance, the differential diagnosis based on CT findings include pancreatic pseudocyst, ovarian cyst, lymphangioma, meconium pseudocyst, hydrometrocolpos, urachal cyst, hemangioma, endometriosis, loculated ascites (usually tuberculous), peritoneal inclusion cysts, cystic teratoma, cystic mesenteric panniculitis (sclerosing mesenteritis), hydatid cyst and urogenital cysts [10,11]. In general, the lack of characteristic clinical and radiological features presents as a diagnostic difficulty.
Localization of these cysts proves to be difficult pre-operatively. CT imaging is important in the management of these cysts as they can help aid the decision to pursue a laparoscopic or open laparotomy approach, when surgical resection is the goal. Other treatment options include drainage, marsupialization and enucleation which were previously thought to be the treatment of choice [2,3,6]. Bowel resection is required in a one third of adult and 50-60% of pediatric cases [6]. Partial excision is not indicated as there is a high recurrence rate with this modality [6]. Sometimes, complete resection and enucleation can not be achieved. In cases where the cyst is imbedded deep within the mesentery or when size is a factor, partial excision with marsupialization of the remainder of the cyst into the abdominal cavity (followed by schlerosis of the cyst lining) is a good option with low recurrence rates [6]. Average recurrence rates in a study with 162 adults and children were 6.1% in one study, and were more likely to occur in partial resections [6]. Conclusion
We have demonstrated that simple per operative controlled aspiration/drainage, followed by complete resection using a small abdominal wound via laparotomy approach is a successful surgical option of a very large mesenteric cyst. Surgical resection is considered the mainstay for therapy as recurrence may occur without complete resection [2,3]. References
