A 40-year multinational retrospective study of 880 Swenson procedures

Abstract

This report reviews the experience of pediatric surgeons in seven cities in North American and Western Europe where the Swenson procedure was performed on 880 patients. Information on the diagnosis, treatment, complications, and long-term results was collected by reviewing the hospital records, the treating physicians' office records, and by interviewing the patients in person or by telephone. A follow-up evaluation was obtained on 814 patients. The patients' ages at the time of the resection ranged from four days to 50 years. The length of follow-up averaged 10.3 years, while the longest follow-up was 39.5 years. The overall postoperative mortality was 2.4% during the entire 40 years of the study. The postoperative mortality has decreased to 1.25% for the last 20 years. Significant factors influencing postoperative mortality included Down's syndrome, the patient's age at the time of the operation, and leak of the distal colonic anastomosis. Most of the patients followed for over 5 years have normal bowel habits, report one to three bowel movements per day, and have no soiling. No patient has urinary incontinence or impotence.
