The W-pouch is a hand-sewn pouch formation constructed using four loops of 12 cm length terminal ileum. The W-pouch was created by John Nicholls in the early 1980s at St Mark's Hospital in London as an augmentation of the S and J …

2023年10月28日 · Ileal pouches are a type of reconstructive surgery to allow you to poop normally through your anus. Surgeons can make three types of internal (inside your body) pouches from your small intestine. They are: J-pouch (most common). S-pouch. Kock pouch, or K-pouch (rare). J-pouches and S-pouches are often shaped like the first letters in their names.

The ileal pouch anal anastomosis (IPAA) has revolutionised the surgical management of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Despite refinement in surgical technique(s) and patient selection, IPAA can be associated with ...

A W-Pouch is constructed using four loops of the small intestine. W-Pouches are very infrequently created and are of more historical significance. Patients with existing W-Pouches are followed and managed in the Pouch Center.

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP/IPAA) is the procedure of choice for patients with ulcerative colitis (UC) requiring surgery (Fig. 1). 1,2 RP/IPAA consists of a J, S, or W ileal reservoir anastomosed either by a stapled or hand-sewn technique.

This is surgery to remove the whole colon (large intestine) and rectum are removed and an internal pouch, or reservoir, is created using the small intestine to store stools which is connected to the anus. This is also often referred to as a ‘J-pouch’, internal pouch or ileal-anal pouch.

In an effort to improve the reservoir capacity of the J-pouch, Nicholls and Lubowski developed the W-pouch. This design configuration employed four loops of ileum intended to improve the frequency of defecation by increasing the reservoir volume compared to a J-pouch.

Introduction: Standard treatment for ulcerative colitis and prevention of malignancy is total proctocolectomy with a neoileal pouch. The ideal configuration of the pouch has been debated. We hypothesized that there was no difference in quality of life between the J …

The use of a J pouch was associated with a significantly higher prevalence of use of anti-diarrhoeal medication (J vs S: OR 2.80, P = 0.01; J vs W: OR 3.55, P < 0.001). Conclusion: All three reservoirs had similar perioperative complication rates.
