[Duodenum-preserving resection of the pancreas head in treatment of benign tumors of the pancreas head].

Benign tumors of the pancreatic head are normally treated by a partial duodenopancreatectomy. This operation has been developed for the treatment of malignant alterations in the pancreatic head and includes resection of the gastric bowel, duodenum and common bile duct. The aim of this study was to evaluate whether the less radical duodenum-preserving pancreatic head resection is a suitable surgical procedure in the treatment of benign pancreatic head tumors. From May 1982 to December 1996, seven patients underwent surgical treatment for benign pancreatic head tumors. Two patients suffered from gastrinoma of the pancreatic head, four exhibited a serous or mucinous cystadenoma, and one patient suffered from an intraductal papillary-mucinous tumor in this region. All patients were treated by duodenum-preserving pancreatic head resection. The operation was easily performed with little blood loss and a low rate of complications. None of the patients had to be reoperated upon due to postoperative surgical complications. After a follow-up period of a median 3 years, six of seven patients were had no recurrence of the disease and were symptom-free. One patient who had initially been operated on for gastrinoma still exhibited high gastrin values postoperatively. The endocrine and exocrine pancreatic function was not impaired in the early and late postoperative phase as compared to the preoperative assessment. From our results, it is concluded that duodenum-preserving pancreatic head resection is an adequately radical, yet organ-preserving procedure for the treatment of benign tumors of the pancreatic head without compromising endocrine and exocrine function.

Acute pancreatitis decreases pancreas phospholipid levels and increases susceptibility to lipid peroxidation in rat pancreas.

The objective of this study was to analyze whether acute pancreatitis leads to changes in the lipid composition and susceptibility to lipid peroxidation of pancreatic membranes. Total lipids, cholesterol, phospholipids, FA, and lipid peroxidation were determined in the pancreatic tissue of rats treated with cerulein and of control rats. In pancreatitic rats, significant decreases in membrane total phospholipid contents (P < 0.05) and in choline and ethanolamine glycerophospholipid levels (P < 0.05 and P < 0.01, respectively), with concomitant significantly higher values of their lysoderivative forms, were found. The cholesterol/phospholipid molar ratio increased by 26%. The unsaturation index of the FA profile decreased significantly (P < 0.01) as a consequence of a decrease in the arachidonic acid content. Incubation of membranes with xanthine oxidase/hypoxanthine-Fe2+/ADP resulted in an increase in the production of TBARS in pancreatitic rats compared to controls. In summary, acute pancreatitis causes changes in the lipid composition of rat pancreatic crude membranes and a greater susceptibility of these membranes to lipid peroxidation.
