ARTICLE HIGHLIGHTS
Research background

Total proctocolectomy with ileal pouch anal anastomosis is performed in adenomatous polyposis syndromes patients to prevent the development of colon cancer. Pouch surgery has a major impact on quality of life - causing increased number of bowel movements and abdominal pain.

Research motivation

Unlike inflammatory bowel disease patients, data regarding response to different treatment modalities targeting pouch-related disorders in adenomatous polyposis patients is scarce.

Research objectives

This study aimed to assess clinical, endoscopic and histologic response to various treatment modalities used in the therapy of pouch related disorders.

Research methods

Files of adenomatous polyposis patients followed prospectively were retrospectively reviewed for initiation of various therapies. Symptoms and endoscopic and histologic signs of pouch inflammation before and after treatment were assessed. Pouchitis disease activity index and its subscores were calculated.

Research results

Overall, intervention was associated with symptomatic relief, mainly decreasing abdominal pain. Daily bowel movements decreased from a mean of 10.3 to 9.3. Mean overall and clinical PDAI scores decreased from 2.58 to 1.94 and from 1.3 to 0.87, respectively. Dietary modifications decreased abdominal pain. Probiotics effectively decreased daily bowel movements, overall and clinical PDAI. While other therapies had minimal or no effects.

Research conclusions

Adenomatous polyposis patients benefit from dietary modifications and probiotics that improve their pouch-related symptoms but respond minimally to anti-inflammatory and antibiotic treatments

Research perspectives

Adenomatous polyposis patients respond differently to pouch related symptoms than ulcerative colitis patients. Dietary modification and probiotics should be considered first line treatment of pouch related disorders in this population.
