Eighty-seven patients with neoplasm (57 cases), pancreatitis (28 cases), or benign biliary obstruction (2 cases) were treated with pyloric preserving pancreatectomy with two postoperative deaths, neither due to abdominal complications. About 50% of patients had delay in recovery of gastrointestinal function. Six and seven patients had clinically significant(More)
One hundred nine patients operated on for bile duct carcinoma were reviewed. Herein, we reported 83 proximal duct tumors, 12 mid-duct tumors, and 14 distal third tumors. Resectability was 10 percent, 33 percent, and 100 percent, respectively, with an operative mortality of 0 percent, 25 percent, and 23 percent. The median survival time and 5 year survival(More)
Between January, 1970, and January, 1984, 113 patients with esophageal achalasia underwent 115 esophagomyotomies at the Lahey Clinic. Twenty-nine patients had been treated on one or more occasions by forceful dilation, and 18 had been operated upon before. Results are based on follow-up studies of 103 patients operated on 1 to 13.5 years ago (average(More)
Between January 1973 and January 1989, 241 patients with Barrett's esophagus were treated at the Lahey Clinic Medical Center, Burlington, Mass. Of these patients, 65 presented with adenocarcinoma in Barrett's esophagus for a prevalence rate of 27%. Of 176 patients followed up for a total of 497 patient-years, adenocarcinoma developed in five patients for an(More)
Pancreatic islets have been isolated from the exocrine pancreas of inbred rats by the collagenase digestion method. Transplantation of isolated islets into the portal venous system of streptozotocin diabetic recipients resulted in complete abrogation of the diabetic state as measured by non-fasting serum glucose level, 24 h urinary output, rate of weight(More)
Of 262 patients with carcinoma of the esophagus or cardia seen at the Lahey Clinic between January 1970 and January 1983, 209 (79.8%) underwent surgical exploration. This report is confined to the 167 operations performed in the division of the senior author. Half of the tumors involved the esophagogastric junction with nearly equal numbers being located in(More)
Reported are eight patients with idiopathic chronic pancreatitis and two patients with alcoholic pancreatitis who had near total distal pancreatectomy for disabling pain and underwent simultaneous segmental pancreatic autotransplantation of the body and tail of the gland to the femoral area in an attempt to prevent or delay the onset of diabetes. The median(More)
This study compared the success of nerve regeneration through conventional nonvascularized and vascularized nerve grafts in the sciatic nerve of rats. The number or size of regenerated axons between the two grafts was not significantly different. In addition, the ratio of axonal diameter to total diameter of the nerve, a measurement linearly related to(More)
