A study of the complications and pelvic visceral function after restorative proctocolectomy and W pouch construction.
OBJECTIVE
Aspects of ileal pouch surgery remain controversial. The authors' single practice experience of 107 operations illustrates many of them. It was hoped that its study would contribute usefully to the debate.


METHODS
Details of all 107 restorative proctocolectomies carried out since the operation was started in Gloucester in 1984 until the study period ended have been kept prospectively. All patients had proctectomy by mesorectal dissection, and 106 had W pouch restoration. Four suffered functional failure requiring reversion to ileostomy and three patients have died. The remaining 99 were sent a questionnaire concerning pelvic visceral function and evidence of pouchitis. Records of all but one of the patients have been reviewed.


RESULTS
Surgical morbidity was low with neither chronic pelvic sepsis, pouch related fistula, pouch haemorrhage nor pouch ischaemia. Mucosectomised patients had similar bowel control to the stapled group. The policy change from routine to selective protective ileostomy proved satisfactory. W pouch function was found to be comparable to that reported from major J pouch series, although anti-diarrhoeal usage was reduced, and was not influenced by either gender, age or time since surgery.


CONCLUSIONS
None of the following reasonably intuitive assumptions seem supported by our findings: that mesorectal excision necessarily poses a greater danger to pelvic visceral function than close rectal dissection, that the greater capacity of W pouches will be reflected in markedly less frequency, that mucosectomy would impair anal control, or that a defunctioning ileostomy is a mandatory precaution. Pouch frequency is less if wind can be passed separately; otherwise functional outcome seems determined by other, non-technical, factors.
