1Current surgical treatment for bile duct cancer显示文摘Since extrahepatic bile duct cancer is difficult to diagnose and to cure,a safe and radical surgical strategy is needed.In this review,the modes of infiltration and spread of extrahepatic bile duct cancer and surgical strategy are discussed.Extended hemihepatectomy,with or without pancreatoduodenectomy(PD),plus extrahepatic bile duct resection and regional lymphadenectomy has recently been recognized as the standard curative treatment for hilar bile duct cancer.On the other hand,PD is the choice of treatment for middle and distal bile duct cancer.Major hepatectomy concomitant with PD(hepatopancreatoduodenectomy)has been applied to selected patients with widespread tumors.Preoperative biliary drainage(BD)followed by portal vein embolization(PVE)enables major hepatectomy in patients with hilar bile duct cancer without mortality.BD should be performed considering the surgical procedure,especially,in patients with separated intrahepatic bile ducts caused by hilar bile duct cancer.Right or left trisectoriectomy are indicated according to the tumor spread and biliary anatomy.As a result,extended radical resection offers a chance for cure of hilar bile duct cancer with improved resectability,curability,and a 5-year survival rate of 40%.A 5-year survival rate has ranged from 24% to 39% after PD for middle and distal bile duct cancer.Yasuji Seyama Masatoshi Makuuchi 2007World Journal of Gastroenterology2007,13,10:74
2KL-6 mucin expression in carcinoma of the ampulla of Vater: Association with cancer progression显示文摘AIM: To assess histochemical expression of KL-6 and its clinicopathological significance in carcinoma of the ampulla of Vater.METHODS: Ampullary carcinoma tissues were collected from 38 patients who underwent pancreatoduodenectomy or local resection. Tissues were subjected to immunohistochemical analysis using KL-6 antibody.RESULTS: Positive staining of ampullary carcinoma cells was observed in 26 (68.4%) cases. Staining was not found in the surrounding non-cancer regions of the ampullary tissues. Remarkable KL-6 expression was observed in invasive carcinoma cells in pancreatic and duodenal tissues and in metastatic carcinoma cells in lymph nodes. Positive KL-6 expression was related to lymph node metastasis (P = 0.020), pancreatic invasion (P = 0.016), duodenal invasion (P = 0.034), and advanced stage of TNM clinical classification (P = 0.010). Survival analysis showed that positive expression of KL-6 was related to a poorer prognosis (P = 0.029).CONCLUSION: The aberrant expression of KL-6 mucin is significantly related to unfavorable behaviors of carcinoma of the ampulla of Vater.Wei Tang Yoshinori Inagaki Norihiro Kokudo Qian Guo Yasuji Seyama Munehiro Nakata Hiroshi Imamura Keiji Sano Yasuhiko Sugawara Masatoshi Makuuchi 2005World Journal of Gastroenterology2005,11,35:10

4Spontaneous rupture of splenic hamartoma in a patient with hepatitis C virus-related cirrhosis and portal hypertension:A case report and review of the literature显示文摘自发的破裂是脾的错构瘤的稀罕复杂并发症。文学的评论揭示了仅仅四个如此的盒子。就我们的知识而言,这是与肝肝硬化和门静脉高血压联系的脾的错构瘤的自发的破裂的第一份报告。一个 53 岁的女人,被跟随在上面因为大动脉的解剖和丙肝病毒(HCV ) 联系了肝肝硬化,与突然的左胸和肩膀疼痛被提交。腹的超声证明流血的 intraabdominal,和显示的计算断层摄影术脾肿大破裂。突现的脾切除术被执行。手术后的功课是平静的,并且病人在第 13 手术后的天被解除。病理揭示了肿瘤是一个破裂的脾的错构瘤。非肿胀的脾的实质揭示了充血变化。我们认为肝肝硬化和门静脉高血压的存在是为脾的错构瘤的自发的破裂的风险因素。Yasuji Seyama Nobutaka Tanaka Yoshio Suzuki Motoki Nagai Takatoshi Furuya Yukihiro Nomura Jimpei Ishii Masakazu Nobori 2006World Journal of Gastroenterology2006,12,13:3
