Objective o explore the effect and mechanisms of transmembrane 4 super family (TM4SF) in digestive system cancer. Methods Articles were reviewed to discuss the biological characteristics of TM4SF in digestive system cancer. Results TM4SF played an important role in migration and invasion of digestive system cancer, including pancreatic cancer, gastric cancer, colorectal cancer, hepatic cancer, esophageal cancer, and so on. TM4SF modulated the cell biological activities by microdomains which were fixed on cell membrane, such as adhesion, migration, invasion, and proliferation. Conclusion TM4SF may be used to predict the metastasis and prognosis of digestive system cancer and may be the targets of therapy of it in the future.
ObjectiveTo explore the value of duodenum-preserving pancreatic head resection for benign lesions in pancreatic head. MethodsClinical data of 14 patients with benign lesions in pancreatic head who were underwent duodenum-preserving pancreatic head resection from Jan. 1995 to Dec. 2012 were retrospectively analyzed, to explore the value of the surgery. ResultsAll surgeries of the 14 patients were success. The operation time were 4.0-6.5 hours (5.2 hours on average), the intraoperative blood loss were 100-1 000 mL (450 mL on average). Postoperative complications happened in 3 patients (21.4%), including pancreatic fistula in 2 patients and biliary fistula in 1 patient, which were cured with non-surgical treatment. No deaths happened during surgery and hospitalization. Of the 14 patients, 13 patients were followed-up for 6 months to 2 years with no recurrence, diabetes, postoperative gastric emptying disorders, and other long-term complications happened. ConclusionDuodenum-preserving pancreatic head resection is the safe and effective treatment of benign lesions in the head of pancreas.
ObjectiveTo evaluate the clinical manifestation, diagnosis, and treatment of intrahepatic biliary cystadenoma (IBCA). MethodsThe clinical date of 12 patients with IBCA from January 2004 to December 2013 in our hospital were retrospectively analyzed. ResultsOf the total 10 patients were female and 2 were male. The average age was 49.0 years old (16-77 49.0 years old). The course of disease were 1 month-3years (average:7 months). The clinical symptoms were right upper abdominal fullness with a sense of pain in 6 patients, right upper abdominal mass in 1 case, jaundice in 1 case, and no symptoms in 4 cases. Enhanced CT examination showed that the tumor complete capsule and there were internal septations in 11 cases, the density of internal septations was different. There was mild enhancement of cyst wall and internal septations in 9 cases. All of 12 cases received surgical resection. Only 1 case showed recurrence in 2 years after operation, the remaining 11 patients had no recurrence. ConclusionsIBCA often occurs in middle-aged women. The main clinical symptoms are abdominal fullness with a sense of pain, right upper abdominal mass or jaundice. Enhanced CT is the main method of diagnosis before operation. Radical resection of IBCA is the best treatment, and can prevent recurrence effectively.
