Summary
Ileal pouch prolapse after restorative proctocolectomy is rare (0.3%). Mucosal prolapse can be managed conservatively or locally, while full-thickness prolapse requires surgery and risks pouch loss.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Surgical Outcomes
Background:
- Restorative proctocolectomy creates an ileal pouch-anal anastomosis (IPAA) for patients with ulcerative colitis or familial adenomatous polyposis.
- Ileal pouch prolapse is a rare but serious complication following IPAA surgery.
Purpose of the Study:
- To review the prevalence, management strategies, and outcomes of ileal pouch prolapse.
- To identify factors influencing treatment success and complications.
Main Methods:
- Retrospective analysis of a prospectively maintained pouch database.
- Inclusion of 11 patients diagnosed with ileal pouch prolapse.
- Analysis of presenting symptoms, surgical history, treatment modalities, and patient outcomes.
Main Results:
- Pouch prolapse occurred in 0.3% of 3,176 patients undergoing IPAA.
- Seven patients had full-thickness prolapse, and four had mucosal prolapse.
- Conservative management or local excision was effective for mucosal prolapse; abdominal surgery had a 57% success rate for full-thickness prolapse, with some requiring continent ileostomy.
Conclusions:
- Ileal pouch prolapse is an infrequent complication with no clear predisposing factors.
- Mucosal prolapse management is typically conservative or local.
- Full-thickness prolapse necessitates surgical intervention and carries a risk of pouch loss, potentially requiring conversion to a continent ileostomy.

01:21Inflammatory Bowel Disease V: Surgical Management
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.
Here are some common surgical interventions for IBD:

01:17Drugs for Treatment of Diarrhea-Predominant IBS
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

01:21Drugs for Treatment of Constipation-Predominant IBS
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
01:24Ostomy Care
Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
