Volvulus of the sigmoid colon at Baragwanath Hospital.

Fifty-six patients treated for sigmoid volvulus over a period of 5 years are reviewed. The purpose of this study is to evaluate our management policy and to compare it with other studies, particularly from other parts of Africa. The patients were evaluated by retrospective allocation into one of three treatment modalities. Patients with clinical evidence of ischaemia underwent a Hartmann's procedure. There was a 33% mortality rate in this group. In those patients who had sigmoidoscopic reduction, a second-stage sigmoidectomy and primary anastomosis were performed. The results in this group were excellent. In the group of patients with failed sigmoidoscopic resection the majority underwent a Hartmann's procedure with a mortality rate of 15%.
