Extraperitoneal manifestation of perforated diverticulitis.Dig Dis Sci. 1993 Nov; 38(11):1985-8.DD
We observed five cases of unusual extraperitoneal presentation of diverticulitis during an 11 year period. During that time, a total of 263 patients were operated for diverticulitis. Patients 1-4 presented with an inflammatory spread of diverticulitis through the abdominal wall; in patient 5 multiple abscesses were present in the left thigh. Inadequate resection and previous radiotherapy in patient 4 might have contributed to the complicated course. In patient 5, poor condition initially allowed only local drainage of the thigh abscesses. Despite laparotomy and sigmoid resection a few days after drainage, the fatal outcome could not be prevented. A more extensive resection and a protecting colostomy might have prevented the fistulous complication in patient 4. A primary resection and abscess drainage might have averted the fatal outcome in patient 5.
