Procedure for prolapsed and hemorrhoids (PPH)


Stapled hemorrhoidopexy / Procedure for prolapsed and hemorrhoids (PPH) 


Based on the concept that interruption of the superior and middle hemorrhoidal vessels, and the upward lifting of the prolapsed anorectal mucosa and repositioning of the vascular cushions back into the anal canal cause the hemorrhoidal tissue to atrophy
For Grade 3 and 4 hemorrhoids
No incisions are made in the somatically innervated, highly sensitive anoderm  


significantly less postoperative pain
Side effect: Rectal perforation, sphincter dysfunction and sepsis
Advantages
1) Simple and quick procedure
2) Less postoperative pain, shorter hospital stay and earlier return to normal activity
3) Similar complication rate as conventional procedure








Staple hemorrhoidopexy
Traditional hemorrhoidectomy
Operative time
Quick, around 30 minutes
40-60 minutes
Postoperative pain
Much less
Painful wound, subsided days to weeks later
Recovery time
Fast, can resume normal activity on next day, avoid strenuous exercise
Slow, requires days to week to resume normal duty
Wound care
No need if not infected
Daily wound dressing, for one to two weeks

Arrests bleeding
Relieves pain, irritation, and inflammation
Guard against infection


Outpatient hemorrhoid treatment
Rubber band ligation, endoscopic ligation
Ultroid system
Sclerotherapy
Infrared coagulation
Bicap electrocoagulation
Cryotherapy
Laser treatment


Banding / Ligation of hemorrhoids
For Grade 2 and 3 internal hemorrhoids

Diagnosis & Management


Diagnosis
Hemorrhoids are diagnosed by prompt clinical examination
Although the most common cause of rectal bleeding is hemorrhoids, we must exclude the most important cause – colorectal cancer. Colonsocopic examination is required if clinically indicated 


Management
Varies from simple reassurance to surgery
Treat for symptomatic disease only
Depends on grading


Four categories
1) Dietary and lifestyle modification  prevention
2) Medications  relieve symptoms
3) Outpatient hemorrhoid treatment
4) Operation


Treatment according to severity 



Dietary and lifestyle modifications
Medications
Outpatient procedures

2)       Prolapse
Ø  Grade 1 – bleeding without prolapse
Ø  Grade 2 – prolapse with spontaneous reduction
Ø  Grade 3 – prolapse with manual reduction
Ø  Grade 4 – incarcerated, irreducible prolapse
3)       Perianal irritation (itchiness) and discharge (mucus)
4)       Pain if the external hemorrhoid thrombosed

l  Hemorrhoids in pregnancy
-          Usually occur in third trimester

1)       Hormonal changes
2)       Obstruction of venous return by the gravid uterus

Hemorrhoid - Introduction



Introduction

Very common disease, affecting more than 80% of adult at sometimes in their life

In the past, hemorrhoid was considered as varicose vein

Recently, it is defined as a vascular cushion resulted from downward displacement of anal cushion which are blood-filled spaces supported by a matrix of fibrous tissue and smooth muscle located in lower rectum

Resulted from chronic straining, leading to local congestion
-          Chronic constipation, diarrhea, prolonged attempts at defecation, prolonged sitting and standing, lack of fibers in diet, etc
-          Local congestion à anal cushions lose their attachment to the underlying rectal wall à prolapse of internal hemorrhoidal tissue through the anal canal
-          As these hemorrhoids engorge à overlying mucosa becomes more friable and the vasculature increases à rectal bleeding

Hemorrhoid is classified as internal, external or internoexternal in relation to dentate line at lower rectum
-          Internal hemorrhoids are located above the dentate line
-          External hemorrhoids are located below the dentate line
-          Interno-external hemorrhoids are extended from above to below the dentate line
