BACKGROUND: Pancreatoduodenectomy is a standard operation for benign and malignant lesions of the periampullary area. Even though the complication and the mortality rates have markedly decreased owing to recent developments in surgical techniques and postoperative care, the complication rates still remain high. Especially, pancreatic leakage is the main cause of death today in a pancreatoduodenectomy, so surgical techniques dealing with this problem have emerged as a major issue. The usual techniques used have been the duct ligation method, the duct occlusion method, a pancreatojejunostomy, and a pancreatogastrostomy. However, a recent trend has been to maintain pancreato-enteric continuity. Thus, the authors used a pancreatojejunostomy with the duct-to-mucosa method to decrease the complications. METHODS: The authors retrospectively reviewed the medical records of 56 patients who had undergone a pancreatoduodenectomy between January 1987 and July 1997 by one surgeon. RESULTS: The male-to-female ratio was 1.4:1 and the mean age was 55.5 years (ranging from 25 to 77). A Whipple's operation was done in 44 cases, and a pylorus-preserving pancreatoduodenectomy was done in 12 cases. All the cases used a pancreatojejunostomy with the duct-to-mucosa method. No pancreatic leakage was observed in any of the 56 cases. The immediate postoperative complication rate was 28.6%, and there was one (1.8%) postoperative mortality due to adult respiratory distress syndrome. Six patients complained of minimal exocrine functional abnormality, but only one patient, who had suffered severe chronic pancreatitis preoperatively, routinely now takes a pancreatic enzyme. However, even after long-term follow up, no endocrine insufficiency has been detected. CONCLUSIONS: Through our experience, a pancreatojejunostomy with the duct-to-mucosa method is a secure and reasonable method and can be used for all patients undergoing a pancreatoduodenectomy.

The objective of this study is to present a new approaches of development systems of test items that will be applied to the National Medical Licensing Examinations. In order to relate all elements of the evaluation process in building a new system, we used the systems approach to problem-solving which involves the development of an overall plan incorporating the interrelated parts of an evaluation process in a sequential pattern. The method we have applied focuses on valid and relevant test items of each subject as an outcome. We have designed the six individual programs that would be a part of whole processes which consists of three different phases such as before-test, test and after-test. The six programs involves sequentially planning of test, requesting test item development, construc ting MCQ, managing test item bank, preparation of test sheets, and test item analysis. One of the characteristic feature of new system is running test item development committees which are made up of subject-matter specialists who together with the nation-wide specialists who are primarily responsible to construct test items, and also with education specialists to refine the structures of each test items.

Pancreatoduodenectomy has been a standard procedure for periampullary cancer. Even when the benign lesion is limited to the pancreatic head, the same procedure has been applied if the lesion should be removed surgically. The duodenum has a key role in the digestive physiologic function. However, removal of the pancreatic head while preserving the duodenum has been considered a very risky procedure because of duodenal ischemia. Since the vascular anatomy of the peripancreatic area was thoroughly examined and a meticulous dissection technique was developed, duodenum-preserving procedure has been tried by several surgeons with success. In this paper we report our experience of duodenum-preserving pancreatic head resection. To our knowledge this is the first report in Korea. The lesions were insulinoma and two serous cystadenomas located at the pancreatic head. Total removal of the pancreatic head was performed trying to preserve pancreaticoduodenal vascular arcade without a Kocher maneuver. The common bile duct was totally preserved in all cases and cholecystectomy with T-tube choledochostomy was performed in one case. The pancreatic duct was ligated just distal to the ampullary portion and the distal pancreas was anastomosed to the posterior wall of the stomach. Operation time was 7 hours 30 minutes in one and 5 hours and 30 minutes in two cases. Transfusion was not required at all. Pancreatic leakage was developed in one case and cured with conservative management. Any complication related to the preservation of the duodenum(leakage or obstruction) had not developed. The patients were discharged on postoperative 46 day(due to pancreatic leakage), 18 days and 11 days respectively. In conclusion, duodenum-preserving pancreatic head resection is recommended for benign pancreatic head lesions, such as benign cystic tumor and localized chronic inflammation.

BACKGROUND: Primary gastric lymphoma is a rare neoplasm that represents 1~4% of all gastric malignancies. The optimal treatment of primary gastric lymphoma remains controversial. This study was designed to examine the prognostic significance of various clinicopathologic factors in patients with gastric lymphoma and to evaluate the role of surgery in the treatment of gastric lymphoma. METHODS: Retrospective study of 71 cases of primary gastric lymphoma which had been undergone laparotomy at the Department of Surgery, Seoul National University Hospital from Jan. 1982 to Dec. 1996 was performed. The authors reviewed clinicopathologic factors of patients and evaluated their prognostic significance. RESULTS: 1) The mean age of the patients was 50 years, and the most prevalent ages occurred in the 6th & the 7th decade. The ratio of males to females was 1.3:1. 2) The presenting symptoms and signs on admission were epigastric abdominal pain & discomfort, weight loss, anorexia, indigestion, and abdominal mass in decreasing order of frequency. 3) The diagnostic accuracy of the gastrofiberscopic biopsies was 67.1% preoperatively. 4) The most common pathologic type was diffuse histiocytic type (57.1%) in Rappaport classification, and diffuse large cell type (47.1%) in NCI Working formulation classification. 5) The distribution of stages according to modified TNM classification was 47.9% stage I, 36.6% stage II, 11.3% stage III, and 4.2% stage IV. 6) Overall, a potentially curative resection was performed in 92.9% of the cases. Treatment modalities included surgery (S), chemotherapy (CT), and radiotherapy (RT) in the following proportions: 33.8% only S, 53.5% S CT, 11.3% S RT, and 1.4% S CT RT. 7) The overall 5-year survival rate was 78.9%. The 5-year survival rates according to stage were 94.1% in stage I, 80.4% in stage II, 30.0% in stage III and 0% in stage IV.
