Surgical management of perforated diverticulitis

The surgical management of perforated diverticulitis remains a subject of controversy, with some workers advocating initial drainage with decompressive colostomy and others favoring primary resection of the perforated colon. To evaluate this problem, we reviewed our experience from January 1, 1960 through December 31, 1978. This retrospective study included 25 patients treated by primary resection and 32 patients treated by staged resection. The duration of postoperative fever and ileus and the incidence and type of postoperative complications were similar in the two groups. Hospital stay and the period of disability were significantly shortened when primary resection with primary anastomosis was carried out initially. Overall, the total cumulative hospital stay was long (p < 0.05) for staged resection (48 days) than for primary resection (39 days). The period of disability was also longer (p < 0.001) for staged (134 days) than for primary resection (75 days). Finally, all patients in the primary resection group left the hospital cured, that is, restored to their premorbid condition, while in the staged resection group only 75 percent were cured; 16 percent were finally discharged with colostomies and 9 percent died. These data suggest that whenever technically feasible, primary resection is the treatment of choice for perforated colonic diverticulitis.
