title: [Sigmoid volvulus].
abstract: The authors report a retrospective study of four patients treated for sigmoid volvulus at the Clinica Chirurgica II of IRCCS Policlinico S. Matteo of Pavia between April 1974 and June 1989. They are collected from a series of 74 consecutive operations for colonic obstruction not related to hernias of the inguinal-crural region (incidence 5.4%). One patient died. The authors review the incidence, epidemiology, etiopathogenetic hypothesis, clinical patterns, nonoperative and operative therapeutic options of the affection. They emphasize the poor prognosis because the sigmoid volvulus usually occurs in elderly ill patients.
