Object During a 5-year period 317 patients presenting with aneurysmal subarachnoid hemorrhage were successfully treated by coil embolization within 30 days of hemorrhage. The authors followed these cases to assess the stability of aneurysm occlusion and its longer-term efficacy in protecting patients against rebleeding. Methods These cases were followed for 6 to 65 months (median 22.3 months) by clinical review, angiography performed at 6 months posttreatment, and annual postal questionnaires. Conclusions Stable angiographic occlusion was evident in 86.4% of small and 85.2% of large aneurysms with recurrent filling in 38 (14.7%) of 259 aneurysms. Rebleeding was caused by aneurysm recurrence in four patients (between 11 and 35 months posttreatment) and by rupture of a coincidental untreated aneurysm in one patient. Annual rebleeding rates were 0.8% in the 1st year, 0.6% in the 2nd year, and 2.4% in the 3rd year after aneurysm embolization, with no rebleeding in subsequent years. Rebleeding occurred in three (7.9%) of 38 recurrent aneurysms and in one (0.4%) of 221 aneurysms that appeared stable on angiography. Periodic follow-up angiography after coil embolization is recommended to identify aneurysm recurrence and those patients at a high risk of late rebleeding.

Twenty-one years ago, Howard published a paper entitled "Forty-one Consecutive Whipple Resections Without an Operative Mortality." That paper stimulated the present analysis of the last 118 consecutive pancreatoduodenectomies (107 Whipple and 11 total resections) performed at the Surgical University Clinic Mannheim from November 1985 to the present day with no deaths. Ninety-one resections were performed for neoplasms and 27 were for complicated chronic pancreatitis. The preoperative evaluation, operative technique, and postoperative care of these cases is discussed in detail and compared to the experience of Howard. While there was general agreement on operative technique, there were differences concerning preoperative evaluation (modern imaging methods) and postoperative care (simplification). In this series 21 postoperative complications required seven relaparotomies. Long-term survival after resection for carcinoma was analyzed for 133 consecutive patients who were shown to have true ductal adenocarcinoma. In 76 patients, who had radical (R0-) resections, the actuarial 5-year-survival rate was 36%. In 44 patients, whose R0-resections for pancreatic cancer occurred more than 5 years ago, the actual survival rate was 25%.

This paper analyses the early postoperative complications after 285 pancreaticoduodenectomies performed during the past 15 years in the Surgical University Clinic, Mannheim. There were 235 partial (Whipple) and 52 total pancreatectomies performed for pancreatic and periampullary tumors (181 patients) and complicated chronic pancreatitis (104 patients). A total of 92 complications requiring relaparotomy in 42 patients ended fatally in nine patients. The overall operative and hospital mortality rate was 3.1%. The most frequent and most dangerous were complications at or around the pancreaticojejunal anastomosis, which occurred 25 times with five deaths. Postoperative hemorrhage was seen in 16 patients; endoscopic treatment in four patients and operation in 12 patients was successful in stopping the bleeding in all but one patient. Eight biliary fistulae either ceased spontaneously (3 patients) or after operative reintervention (5 patients) without any mortality. Control of these complications depends on four lines of approach: (1) before operation: optimal preparation of the jaundiced patient including endoscopic transpapillary decompression of the common duct; (2) during operation: a meticulous and standardized technique is mandatory; (3) after operation: continuous observation in the surgical intensive care unit is essential for the timely detection of possible complications; and (4) early reintervention can salvage the great majority of these patients with deleterious complications.
