A selective approach to restorative proctocolectomy without ileostomy: a single centre experience

Abstract

OBJECTIVE: A single surgeon series on complications and functional outcomes following restorative proctocolectomy (RPC) is presented. METHOD: An ethically-approved database was used to collect data on all patients undergoing RPC at a single institution. Patient demographics, operative details, complications and functional outcomes were assessed. The impact of ileostomy omission on outcomes was also assessed. RESULTS: Two hundred patients undergoing RPC between 1987 and 2006 were included. There were 122 (61.0%) males and the mean age at surgery was 37.6 years. A J pouch was constructed in 199 (99.5%) patients and an ileostomy omitted in 160 (80.0%). Since adopting a selective policy after the 36th consecutive patient in the series, only 9 (5.5%) patients have had an ileostomy constructed at the time of pouch construction. Complications occurred in 112 (56.3%) patients, with anastomotic stricture (20.6%) and pouchitis (28.6%) being the most common. Anastomotic stricture was more common in those patients receiving an ileostomy (43.6%vs 15.0%, P < 0.001), as were pouch-cutaneous fistulae (5.1%vs 0.6%, P = 0.039) and pelvic sepsis (15.4%vs 5.0%, P = 0.023). Functional outcomes were good, with median 24-h stool frequency of five motions at 1 year. There was increased urgency to defaecate which in part may be due to a significant decline in the use of antidiarrhoeal medication during follow up. CONCLUSIONS: Selective omission of a covering ileostomy in most cases can produce good results following RPC with no increase in the risk of septic complications or pouch failure, and a decreased risk of anastomotic stricture, with maintenance of good function in the majority.
