The aim of this project was to establish and maintain an internet-based database of all ileal pouch procedures performed in major centres in Australasia.Method
The initial three colorectal units contributing data are Auckland, northern Brisbane and Central Sydney Area Health Service. A web-based database was designed. The data collection method was tested on a subgroup of 20 patients to ensure functionality. Data were collected in five main categories: patient demographics, preoperative data, operative details, postoperative complications and functional results.Results
Initial data are presented for 516 patients [363 J, (70%), 133 W (26%), 16 S pouches (3%)]. There were two deaths within 30 days (0.4%). The anastomotic leak rate overall, in handsewn (HSA) and stapled anastomoses (SA) respectively was 5.0%, 8.5% and 3.3% (P = 0.02 for difference HSA vs SA). Incidence of pouchitis was 20% (ulcerative colitis 23%, Crohn's disease 20%, indeterminate colitis 22%, familial adenomatous polyposis 9%). Incidence of anal stricture requiring intervention (11% overall) was significantly greater in HSAs than in SAs (16%vs 9%, P = 0.02). Incidence of small bowel obstruction at any time postoperatively was 16%. Functional data were available for 234 patients. The median frequency of bowel actions during waking hours was significantly less in W pouches than in J pouches (four vs five, P = 0.0005).Conclusion
A national web-based database has been developed for access by all Australasian colorectal units. Initial Australasian data compare favourably with other international studies. Pouchitis continues to be a long-term problem. The leak rate and rate of late anal stricture requiring a procedure are higher if the anastomosis is handsewn rather than stapled. Functional results are better with the W pouch than with the J pouch.
