This document discusses haemorrhoids, including their anatomy, classification, etiology, clinical features, complications, grading, and treatment options. Haemorrhoids are classified as internal or external depending on their location relative to the dentate line. Common causes include straining during bowel movements and sedentary lifestyles. Clinical features may include bleeding, pain, irritation, and prolapse. Treatment ranges from conservative options like lifestyle changes to surgical procedures like rubber band ligation, injection sclerotherapy, and haemorrhoidectomy. Complications of haemorrhoidectomy can include pain, stricture, and incontinence.

5. CLASSIFICATION
Depending on anal origin within anal canal and relation to
dentate line haemorrhoids divided into:
 Internal haemorrhoids
 External haemorrhoids
 Interoexternal haemorrhoids (external extensions of
internal haemorrhoids)

6.  Symptomatic anal
cushions
 Lie above dentate line
 Lie in 3, 7 and 11 o’clock
positions
 Develop from embryonic
endoderm
 Covered by columnar
epithelium
 Not supply by somatic
sensory nerves, so painless
 Relate to venous channels of
inferior haemorrhoidal
plexus deep in skin
surrounding the anal verge
 Lie below dentate line
 Not true haemorrhoids
 Develop from embryonic
ectoderm
 Covered by squamous
epithelium
 Innervated by cutaneous
nerve that supply perianal
area, so painful
Internal haemorrhoids External haemorrhoids

7. ETIOLOGY
Sedentary life style, Smoking and alcohol
Stress, Family history

8. Causes of secondary internal haemorrhoids:
( in between 3, 7 and 11 o’clock positions)
 Carcinoma of anorectum (MC)
 Local, e.g. anorectal deformity, hypotonic anal sphincter
 Abdominal, e.g. ascites
 Pelvic, e.g. gravid uterus, uterine neoplasm (fibroid,
carcinoma of the uterus or cervix), ovarian neoplasm,
bladder carcinoma
 Neurological, e.g. paraplegia, multiple sclerosis

9. ETIOPATHOGENESIS
 Straining and constipation
Low fiber diet
Less bulky stool
Straining at defecation
Increased intraanal pressure
Decreased venous return
Enlarged haemorrhoidal venous cushions

10. CLINICAL FEATURES
 Bright-red, painless bleeding
 Mucous discharge
 Prolapse
 Peri anal pruritus and irritation
 Pain only on prolapse
 Acute pain when incarcerated/
strangulated
 Thrombosed external haemorrhoids/ perianal haematoma
may present with as sudden onset, olive-shaped, painful
blue subcutaneous swelling at anal margin (‘a 5-day,
painful, self-curing lesion’)
 Skin tags (in external haemorrhoids)

11. COMPLICATIONS OF HAEMORRHOIDS
 Strangulation and thrombosis
 Ulceration
 Gangrene
 Severe haemorrhage
 Portal pyaemia
 Fibrosis
Prolapsed strangulated
piles on the left

12. GRADING OF INTERNAL HEMORRHOIDS
Ther Adv Chronic Dis 2017;8(10):141–147
Patients may experience painless bleeding with any grade

15.  Per rectal examination
 Proctoscopy
 Colonoscopy for exclusion of other causes of rectal
bleeding, especially colorectal malignancy
 CBC
 Coagulation profile

16. TREATMENT
 Conservative
 Non-surgical
a) Injection sclerotherapy
b) Rubber band ligation
c) Cryotherapy (Lloyd Williams) not often used
d) Infrared photocoagulation (Leicester) not often used
 Surgical
a) Open hemorrhoidectomy (Milligan–Morgan)/ MMH- Gold standard
b) Closed hemorrhoidectomy (Ferguson)
c) Diathermy hemorrhoidectomy
d) Laser hemorrhoidectomy
e) LigaSure hemorrhoidectomy
f) Harmonic scalpel hemorrhoidectomy
g) Semi-closed hemorrhoidectomy
h) Submucosal hemorrhoidectomy (technique of parks)
i) Hemorrhoidal artery ligation
j) Farag procedure
k) Stapled hemorrhoidopexy/ PPH

17. CONSERVATIVE TREATMENT
 Attempts at normalizing bowel and defaecatory habits:
 only evacuating when natural desire to do so arises
 adopting a defaecatory position to minimize straining
 addition of stool softeners and bulking agents to ease
defaecatory act
 proprietary creams can be inserted into rectum at night and
before defaecation

20. INJECTION SCLEROTHERAPY
 Aim: to create fibrosis, cause obliteration of vascular
channels and hitch up anorectal mucosa
 Submucosal injection of 5% phenol in arachis oil or
almond oil
 Left lateral position and under direct vision with a
proctoscope, about 5 mL of sclerosant is injected into
apex of pile pedicle
 Procedure is repeated for each pile
 Reassessed after 8 weeks
 If necessary, repeat injections
Correct site (cross) for
injecting a haemorrhoid

21.  Pain upon injection means that needle is in wrong place
 Too superficial injections: rapid bulging of mucosa, which
turns septic sequelae
 Too deep injections: disastrous consequences, including
pelvic sepsis, prostatitis, impotence and rectovaginal fistula

22. RUBBER BAND LIGATION
 Efficacious for more bulky piles, but associated with more
discomfort
 Barron’s bander is a commonly available device
 Used to slip tight elastic bands onto base of pedicle of each
haemorrhoid
 Bands cause ischaemic necrosis of piles, which slough off
within 10 days; this may be associated with bleeding
 Three piles may be treated at one session
 Process may be repeated after several weeks if necessary

23. When an internal hemorrhoid is present in anorectal canal, an anoscope may be used as a
guide to identify hemorrhoidal complex.
A) With a speculum in place, a ligator is positioned over base of hemorrhoid, isolating it.
Some ligators use forceps, whereas others use suction to draw hemorrhoid taut.
B) Once the ligator is positioned at its base, bands are released
C) After the procedure is completed, the constricting bands remain in place until they
eventually fall off (typically because the tissue distal to the constricting bands sloughs)

24. INDICATIONS FOR HAEMORRHOIDECTOMY
 3rd and 4th degree haemorrhoids
 2nd degree haemorrhoids that have not been cured by
non-operative treatments
 Fibrosed haemorrhoids
 Interoexternal haemorrhoids when the external
haemorrhoid is well defined
 Presence of anorectal conditions requiring surgery
(fistula, fissure, large skin tag)
 Haemorrhoids complicated by strangulation
 Patient preference

25. OPEN HEMORRHOIDECTOMY
 Milligan–Morgan hemorrhoidectomy (MMH)
 Current gold standard for surgical management
 Hemorrhoidal tissue and vessels involved are excised with
placement of a suture at hemorrhoid pedicle
 But incisions are left open
 Often, because of location, technical difficulties, or extensive
disease with gangrenous hemorrhoidal tissue, open
approach required
 More useful for avoiding subsequent anal stenosis

26. a) artery forceps applied
b) dissection of left lateral
pedicle
c) transfixion of the pedicle

27.  To avoid stricture formation, it
is necessary to ensure that a
bridge of skin and mucous
membrane remains between
each wound
 If it looks like a clover, the
trouble is over
 if it looks like a dahlia, it is
surely a failureAppearance of anus at
conclusion of operation

28. CLOSED HEMORRHOIDECTOMY
 Ferguson hemorrhoidectomy (FH)
 Differs from MMH as the wound is sutured primarily
 After hemorrhoidal pedicle has been mobilized, an
absorbable suture is usually placed at pedicle site
 After hemorrhoidal bundle is excised, mucosal wound and
skin are completely closed with a continuous suture
 MMH may be overall better than FH particularly as regards
complication rate

29. (a) Haemorrhoidal tissue is
excised
(b) Bleeding is controlled by
diathermy
(c) Defect is closed with a
continuous suture after first
undermining anoderm on
each side

30. COMPLICATIONS OF HAEMORRHOIDECTOMY
Early
 Pain (results from sphincter spasm, damage to nerve endings,
insertion of hemostatic gauzes and damage to mucosa)
 Protracted recovery time (a minimum of 4 weeks with MMH)
 Acute retention of urine
 Reactionary haemorrhage
Late
 Secondary haemorrhage (7th – 8th POD)
 Anal stricture
 Anal fissure
 Fecal incontinence

31. CIRCULAR STAPLED HEMORRHOIDOPEXY
 Also known as ‘procedure for prolapse and hemorrhoids
(PPH)’ or stapled anopexy/ mucosectomy/ prolapsectomy
 Introduced by Longo A in 1998
 Employs a circular stapling device, which removes mucosa
and submucosa circumferentially 2-3 cm above dentate line,
anastomosing proximal and distal edges
 Interrupting blood supply to remnant hemorrhoidal tissue
 Less painful and allows quicker recovery than MMH
 High recurrence rate (PPH versus MMH 5.7% vs. 1% at 1 year
and 8.5% vs.1.5% overall)*
*Cochrane Database Syst Rev 2006;(4):CD005393.

33. DIATHERMY HEMORRHOIDECTOMY
 With diathermy, coagulation occurs at temp. >150 ℃
 Formation of an eschar that seals the bleeding area
 Compared with conventional hemorrhoidectomy:
 Less bleeding
 Shorter operating time
 Lower postoperative analgesic requirement, but with similar post-
operative pain
World J Surg Proced 2014; 4(3): 55-65

34. LIGASURE HEMORRHOIDECTOMY (LH)
 LigaSure vessel sealing system® (Valleylab) uses a bipolar
electrothermal device without need for sutures, i.e.,
sutureless hemorrhoidectomy
 Aim:
 avoiding painful diathermy burns in the richly innervated anal canal
 allowing better tissue adhesions at the wound site
 decreasing incidence of postoperative hemorrhage
 Shorter operative time
 Postoperative pain and urinary retention
 Day-case surgery
 Earlier return to work
 Additional cost of the disposable device
World J Surg Proced 2014; 4(3): 55-65

35. HARMONIC SCALPEL HEMORRHOIDECTOMY (HSH)
 Harmonic scalpel® (J & J, Ethicon) is an ultrasonically-
activated instrument
 Vibrates at a rate of 55000 MHz per second
 Able to coagulate small- and medium-sized vessels by
converting electrical energy to a mechanical one
 Less lateral thermal damage
 Benefit of HSH with respect to operative time, blood loss,
postoperative pain, length of hospital stay, and return to
normal activity
 Increased cost

36. SUBMUCOSAL HEMORRHOIDECTOMY
(TECHNIQUE OF PARKS)
 Designed to reduce postoperative pain and avoid anal and
rectal stenosis
 Indicated for 2nd to 4th degree hemorrhoids
 It includes hemorrhoidectomy with preservation of anal canal
mucosa, reducing surgical wound dimensions and leading to
a shorter healing time
 Mucosa is not included in ligation leads to reduced
postoperative pain
 Surgical time is longer
 Recurrence rate is higher
 Greater risk of bleeding during surgery and postoperatively
World J Surg Proced 2014; 4(3): 55-65

37.  A Y-shaped incision is made at mucocutaneous junction,
between upper mucosa of the anal canal and anorectal
junction, as an inverted racket incision
 Vascular pedicle is separated from mucosa and sphincter
plane, connecting it afterwards
 Mucosa is then closed with running suture, leaving a small
area open in the perianal region for drainage

38. DOPPLER-GUIDED HEMORRHOIDAL ARTERY LIGATION
 First described by Morinaga et al in 1995
 Performed under sedation and/or LA
 Involves a proctoscope with a doppler transducer
integrated in probe
 Sequential identification of position and depth of superior
rectal arterial branches (usually 5-7 are found at one level)
 Selectively ligated 2-3 cm above dentate line at two levels
1-1.5 cm apart by absorbable sutures via a lateral ligation
window within scope
 interference with blood supply suppresses bleeding and
volume of hemorrhoids
 Symptomatic relief is usually evident within 6-8 weeks

39. FARAG PROCEDURE
 Alternative method to ligate hemorrhoidal artery without
doppler guidance
 Piles suture, in which three interrupted sutures are used to
interrupt the blood flow to the prolapsed hemorrhoids
 First suture is passed through mucosa at proximal end of
internal hemorrhoids to occlude superior rectal vessels
 Second suture is passed into distal end of internal
hemorrhoids above dentate line to interrupt connection
between the internal and external hemorrhoidal plexuses
 Third suture between previous two sutures
 Not widely accepted (interruption of the blood flow to
hemorrhoidal cushions cause initial painful congestion)
World J Surg Proced 2014; 4(3): 55-65

40. SEMI-CLOSED HEMORRHOIDECTOMY
 Involves the pectineal line repair
 Internal hemorrhoid is forced outwards, becoming fully exposed
 For the repair of rectal mucosa
 In upper limit of internal hemorrhoid; 3-4 full-thickness sutures
are made radially, involving mucosa and submucosa
 Craniocaudal length of hemorrhoid to be resected
 Mucosa and submucosa are cut between the ligations
 External part of skin plexus is removed until dentate line with a V-
shaped incision or a racket incision with an external base
 Perfect for voluminous and proximally extended internal
hemorrhoids, whose full dissection would cause a very high
resection of the rectal mucosa
