Outcome of microscopically nonradical, subtotal pancreaticoduodenectomy (Whipple's resection) for treatment of pancreatic head tumors.

Abstract

From 1983 to 1992 a total of 240 patients with a pancreatic head tumor underwent laparotomy to assess the resectability of the tumor. In 44 patients the tumor was not resected because of distant metastases (n = 20) or major vascular involvement or local tumor infiltration (n = 24) not detected during the preoperative workup. A palliative biliary and gastric bypass was performed in these patients. All other patients underwent a subtotal (Whipple's resection, n = 164) or total (n = 32) pancreaticoduo-denectomy. However, in 56 cases after Whipple's resection, microscopic examination of the specimen showed tumor invasion in the dissection margins. For this reason, these resections were considered palliative. We compared hospital mortality, morbidity, and long-term survival of patients who had undergone a biliary and gastric bypass for a locally advanced tumor (group A, n = 24) with a matched group of patients who had undergone a macroscopically radical Whipple's resection that on microscopic examination proved to be nonradical (group B, n = 36). Both groups were comparable with regard to age (mean 61 years in both groups), duration of symptoms (8 weeks in group A and 10 weeks in group B), and tumor size (mean 4.25 cm in group A and 4.30 cm in group B). Median postoperative hospital stay was 18 days in group A and 25 days in group B. Postoperative complications (intraabdominal abscess, gastrointestinal hemorrhage, anastomotic leakage, delayed gastric emptying) occurred in 33% of patients in group A and in 44% of patients in group B. Hospital mortality was 0% and 3% in group A and group B, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
