Anal sphincter function after colectomy, mucosal proctectomy, and endorectal ileoanal pull-through
Archives of Surgery (Chicago, Ill. : 1960)
|May 1, 1984
Summary
Endorectal ileoanal pull-through surgery preserves anal sphincter function and continence in patients with inflammatory bowel disease or polyposis. Post-operative stool frequency remains acceptable, indicating successful functional preservation.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Physiology
Background:
- Colectomy with endorectal ileoanal pull-through is a surgical option for various colorectal conditions.
- Assessing the impact of this procedure on anal sphincter function is crucial for patient outcomes.
Purpose of the Study:
- To prospectively evaluate anal sphincter function before and after endorectal ileoanal pull-through.
- To determine the effect of the surgery on continence and stool frequency.
Main Methods:
- Anorectal manometry was performed on 21 patients pre- and post-operatively.
- Balloon dilation of the ileal pouch was used to assess sphincter response.
- Stool frequency was monitored at one and three months post-surgery.
Main Results:
- Maximal anal sphincter resting pressure decreased post-operatively, but squeeze pressure response improved.
- Balloon dilation induced appropriate internal and external anal sphincter responses in most patients.
- Mean 24-hour stool frequency decreased from 7.6 to 6.2 between one and three months.
Conclusions:
- Endorectal ileoanal pull-through surgery maintains near-normal anal sphincter function.
- The procedure effectively preserves continence and leads to acceptable stool frequency.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

01:25Assessment of the Rectum and Anus
1.4K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.

01:09Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

01:26Feces Formation and Defecation
4.3K
After spending 3 to 10 hours in the large intestine, chyme loses a lot of water and becomes feces, the final product of digestion. Feces consist of undigested dietary fiber such as cellulose, mucus, sloughed-off epithelial cells, and microbes. The descending and sigmoid colon stores feces and uses haustral contractions to dry it out but retains enough water to give it a semi-solid texture.
The mass peristalsis then pushes the feces into the rectum, which stretches the rectal walls to activate...

01:26Physiology of the Gastrointestinal System III: Elimination
1.7K
The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...
