Indications, technique and efficacy of organ preserving pancreatectomy / 中华外科杂志

<p><b>OBJECTIVE</b>To discuss the proper surgical management of pancreatic benign and low-grade malignant potential neoplasm.</p><p><b>METHODS</b>The experience of 72 cases who accepted organ preserving pancreatectomy from January 1990 to May 2010 was analyzed retrospectively. There were 24 male and 48 female, aged from 15 to 68 years with mean age of 46 years. There were 9 cases underwent duodenum-preserving resection of the head of the pancreas, 29 cases underwent spleen-preserving distal pancreatectomy, 11 cases underwent middle segmental pancreatectomy, 23 cases underwent tumor extirpation of huge pancreatic cancer in pancreatic head and body.</p><p><b>RESULTS</b>Pancreatic fistula and biliary fistula in 1 case respectively were cured among who accepted duodenum-preserving resection of the head of the pancreas. Pancreatic fistula was found in 3 cases who accepted spleen-preserving distal pancreatectomy. Pancreaticobiliary anastomotic bleeding in 1 case was cured among who accepted middle segmental pancreatectomy. Pancreatic fistula was found in 5 cases among who accepted tumor extirpation of huge pancreatic cancer in pancreatic head and body, and liver metastasis was found in 3 cases at 6, 12, 16 months after surgery respectively.</p><p><b>CONCLUSIONS</b>Organ preserving pancreatectomy can obviously reduce operative injury to patients, its therapeutic effect is similar to that of classical operation, it is the first option of benign and low-grade malignant potential neoplasm.</p>

Diagnosis and surgical treatment of 98 cases with adult primary retroperitoneal malignant tumor / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the diagnosis and surgical treatment of adult primary retroperitoneal malignant tumor (APRMT).</p><p><b>METHODS</b>The clinical data of 98 cases with APRMT underwent resection from January 1990 to April 2003 were analyzed retrospectively.</p><p><b>RESULTS</b>Among the 98 cases, complete excision were performed in 79 cases (80.6%), palliative excision in 16 cases (16.3%), tumor biopsy only in 3 cases (3.1%). Resection of involved adjacent organs were carried out in 25 cases (25.5%) and the re-operation rate for recurrence was 28.6% (28 cases). The 1, 3, 5 year survival rates for 79 cases with complete resection were 93.7%, 73.4% and 34.2%, respectively. The 1, 3, 5 year survival rate for 16 cases with palliative resection were 75.0%, 6.3% and 6.3%, respectively.</p><p><b>CONCLUSIONS</b>Certain imaging examinations are crucial to the diagnosis and preoperative evaluation of APRMT. Resection of the involved organs could improve resection rate and prognosis. For the recurrent cases, earlier reoperation is strongly recommended.</p>

The retrospective analysis of HBV and HCV infection in cholangiocarcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>In order to study the diagnosis and treatment of HBV and HCV infection.</p><p><b>METHODS</b>We retrospectively analysed clinical data of 680 patients with cholangiocarcinoma from 1995 to 2001 and stated by SPSS software.</p><p><b>RESULTS</b>(1) The fastigium of cholangiocarcinoma was 60 - 65 years old. The incidence of cholangiocarcinoma was higher in aged males and the sex ratio (male:female) was 1.36:1. (2) The proximal cholangiocarcinoma was most (41.6%) and distant cholangiocarcinoma was secondly (28.7%). (3) Most patients of cholangiocarcinoma were late. The resection rate was low and the rate of radical operation was 21.6% (147/680). (4) The incidence of proximal cholangiocarcinoma was higher in the positive Serologic marks for HBV and HCV and course of diseases was short. Moreover, the pathology of. positive Serologic marks for HBV and HCV trended to low-differentiation and invasion, metastasis and the resection rate was lower.</p><p><b>CONCLUSIONS</b>Cholangiocarcinoma is common in the aged males. The infection of HB(C)V and hilar cholangiocarcinoma are correlated and incline to the proximal bile duct. The hilar cholangiocarcinoma infected HB(C)V may have higher malignant degree in biological characteristics and more badly prognosis.</p>
