Gender of the patient may influence perioperative and long-term complications after restorative proctocolectomy

Aim Gender-related differences in preoperative characteristics and early and long-term outcome for patients undergoing ileal pouch anal anastomosis (IPAA) have not previously been well studied. Method All male and female patients undergoing IPAA at a single centre between 1983 and 2008 were compared for perioperative variables and long-term outcome. Statistical tests were used as appropriate. A multivariate analysis was performed to evaluate the effects of gender on pouch failure. Results Female patients (n=1495) were younger than male patients (n=1912) (P<0.001). Surgery type and pouch configuration were similar, although male gender was associated with a higher use of ileostomy (P<0.001) and a higher incidence of 30-day anastomotic separation (P=0.001). During a median follow up of 9.9 (female) and 9.3 (male) years, female patients were more likely to develop bowel obstruction (20.8 vs 16.7%, P=0.02) and pouch-related fistula (10.9 vs 7.6%, P=0.001). Women had a higher number of daily bowel movements than men (P=0.001), and more frequently had urgency (P=0.001), daily seepage (P=0.01) and pad use (P<0.001). A higher percentage of female patients reported dietary (P<0.001) and work (P=0.022) restrictions and lower mental component of the Short-Form 36 quality of life score (P=0.018). On multivariate analysis of perioperative variables, female gender was associated with pouch failure (P=0.05). Conclusion The gender of the patient seems to be associated with specific differences in preoperative variables and postoperative outcomes for patients undergoing IPAA. © 2011 The Authors.
