This paper includes a brief historic summary of the surgical aspects of diverticular disease and of corresponding developments in the Massachusetts General Hospital from 1911 to the present. The 350 cases observed in 1974-1983 are compared with 338 seen in the previous decade. Major trends include a decrease in hospital admissions for diverticular disease but a sustained number of operations; increased severity of the disease in hospitalized patients manifested by an increased percentage of patients with immunosuppression or serious other diseases (p less than 0.001), an increased number with sepsis and general peritonitis (p less than 0.001); an increased percentage of cases with one-stage resection and anastomosis (p less than 0.02); in patients with general peritonitis, resection of the perforated segment at the time of the original operation was accompanied by the lowest mortality (p less than 0.02); incidental splenectomy appears to be dangerous, with three deaths in eight cases; and overall mortality in the last decade is 6.4%; for emergency cases 10.2%, for urgent 9.7%, and for elective cases 2.4%.

A retrospective study of 1068 patients who had operations for peptic ulcer disease in the 12-year period from January 1, 1974, to January 1, 1986, permits these conclusions: The number of patients admitted to the Massachusetts General Hospital (MGH) has declined steadily in the years of this study--1974-1986. The average number of patients admitted with a diagnosis of peptic ulcer disease in precimetidine years--1974, 1975, and 1976--and in recent years--1982, 1983, and 1984--shows a decline of 39.3% in admissions. In the same periods, the average number of operations per year has declined from 92 in precimetidine years to an average of 71 (16.5%) recently. The decline has been greatest in patients operated on electively for duodenal ulcer. Operations for massive hemorrhage and acute perforations and the number of deaths have remained nearly constant. The overall mortality rate was 10.3%. The mortality following elective operations for pain was 0.5%; for urgent operations, including those for obstruction, 4.5%, and for bleeding other than massive, 7.5%; and for emergency operations, including those for acute perforation, 20.9%, and for massive hemorrhage, 22.1%. The main causes of death were organ failure (most commonly of the lungs) and sepsis. Early complications were documented 345 times and were followed by reoperation in 84 cases, or 7.4% of the total. Delayed stomal function was noted in 63 cases and required reoperation in 14. It was most common after Roux anastomoses and required operative intervention most commonly after gastric resection, Billroth I (GRBI). Delay was three times as common when vagotomy (V) was added to GR. Early postoperative hemorrhage was a serious complication when it occurred after operations for acute perforations or massive hemorrhage. The incidence was 3.7% after suture of a perforation; after operations for acute massive hemorrhage, it was 4.3% after pyloroplasty and vagotomy, with or without arterial ligation [PV(L)], and 0.3% after GR, with or without arterial ligation [GR(L)]. Late complications led to reoperation in 66 cases (6.2%). The most important were recurrent ulceration and alkaline gastritis. Recurrence rates after a minimum follow-up of 5 years (based on survivors of initial procedures and a second operation, both in the MGH) were 20.5% after suture of a perforation, 6.2% after PV, 2.3% after GRBII, and 0.4% after GRVBII. These figures are lower than expected; incomplete follow-up and improved medical care are factors.(ABSTRACT TRUNCATED AT 400 WORDS)
