Long-term results of haemorrhoidectomy.

Objective: To assess the long-term functional results of Milligan-Morgan haemorrhoidectomy.

Methods: Retrospective multicentre study. Methods: One university hospital, one county hospital, and two community hospitals, Sweden. Methods: 507 of 556 patients who were operated on for haemorrhoids by the Milligan-Morgan technique between January 1987 and December 1995. Methods: A questionnaire was sent to all 507 patients, the questions in which focused on functional results and satisfaction. Methods: Patients' satisfaction and symptoms of anal incontinence after haemorrhoidectomy.

Results: 418 of the 507 responded (82%). Altogether 279 patients (67%) reported a successful result, while 139 patients (33%) reported impaired anal continence. 40 of the 139 patients (29%) claimed that the incontinence was a direct result of the haemorrhoidectomy. Female sex (p = 0.005) and an operation for hygienic problems (p = 0.02) were associated with a higher risk of incontinence.

Conclusions: Impaired anal continence is common after Milligan-Morgan haemorrhoidectomy and a large proportion of affected patients relate their problems to the operation.
