[Perforations of the colon. Apropos of 74 cases].

74 colic perforations were surgically handled between 1975 and 1988. Among the non-traumatic perforations, which represent 74% of this series, 39 cases (71%) complicated the course of acute diverticulitis, 9 cases (15%) were due to cancers and 7 cases (13%) were of miscellaneous origin. Traumatic perforations (26%) were iatrogenically induced in 84% (16 cases). In 78% the perforation was located in the sigmoid or recto-sigmoid. The treatment consisted in performing either a diverting colostomy (30 cases--40%) or a colic resection (44 cases--60%) with or without immediate anastomosis (respectively 10 cases--13.5% and 34 cases--46%). The overall mortality was 10.8%, which referred to etiology, turns to be 15% (3/19 cases) in traumatic perforations, 13% (5/39 cases) in diverticulitis and 0% in cancer. Related to treatment, mortality reached 23% for derivation and drainage procedure and 2% for resection. Post-operative complications were respectively 10% and 47%. Among post operative complications (22 cases--29%) 11 patients were reoperated on with an additional mortality of 18%. These results give strong evidence to the reliability and value of urgent colic resection in perforated colon and enhance the necessity of undelayed operation.
