Lymphatic spreading pattern of intrahepatic cholangiocarcinoma 总被引:9,自引:0,他引:9
BACKGROUND. There have been very few reports on the pattern of lymphatic spread of intrahepatic cholangiocarcinoma. This pattern was elucidated to help define the rational extent of radical lymph node dissection. METHODS. Thirty-nine consecutive patients who underwent hepatectomy with radical lymph node dissection were reviewed retrospectively. RESULTS. Lymph node metastases were detected in 24 of the 39 patients (62%). The metastatic nodes were found in the hepatoduodenal ligament, along the common hepatic artery, around the abdominal aorta, on the posterior surface of the pancreas head, along the left gastric artery, along the superior mesenteric artery, around the celiac artery, along the lesser curvature of the stomach, and around the cardia. The nodal involvements along the left gastric artery, along the lesser curvature, or around the cardia were recognized only in the left peripheral and hilar types of cholangiocarcinoma, while all other sites included both the left or right peripheral type and the hilar type cholangiocarcinoma. CONCLUSIONS. Intrahepatic cholangiocarcinomas, irrespective of their intrahepatic location, mainly spread to the nodes in the hepatoduodenal ligament, then to the para-aortic nodes, retropancreatic nodes, or common hepatic artery nodes. In addition to these spreading routes, the left peripheral type or hilar type of cholangiocarcinoma tends to spread along the left gastric nodes through the lesser curvature. 相似文献

目的 探讨远端胃癌患者正常肝动脉及异常肝动脉周围淋巴结的微转移及清扫的必要性,为胃癌D2根治术中合理地选择淋巴清扫范围提供依据。方法 选择广西医科大学第一附属医院胃肠外科2008年6月至2010年6月间由同一手术者进行远端胃癌D2根治术的60例胃癌患者,对正常肝动脉及源自肠系膜上动脉异常肝动脉周围淋巴脂肪组织行重组人细胞角蛋白20(CK20)和CEA微转移免疫组化检查,从而判断正常及异常肝动脉周围是否有淋巴结转移的发生。结果 本组经CK20和CEA微转移免疫组化测定,正常肝动脉周围淋巴结转移率为27%,患者年龄、肿瘤大小、Borrmann分型、TNM分期均为转移的影响因素。存在源自肠系膜上动脉异常肝动脉的患者共7例,变异率为12%,其中走行于胰腺前方的1例,胰腺后方的6例,胰前、后型异常血管周围淋巴组织中未发现淋巴结转移。结论 CK20和CEA免疫组化检查是检测淋巴结微转移良好的指标;对于年龄≥60岁、肿瘤>3 cm、BorrmannⅢ~Ⅳ型的远端胃癌患者,走行正常的肝动脉周围淋巴结转移率甚高,术者应重视对此处淋巴结的清扫;发自肠系膜上动脉的异常肝动脉周围淋巴结转移率则很低。 相似文献

Gastric lymphatics in 200 patients of gastric cancer were studied by injection of activated carbon particles (CH44). By observing the carbon flow intraoperatively and examining stained lymph nodes, gastric lymphatics for individual regions (cardia, lesser curvature, left greater curvature and right greater curvature) were evaluated. The cardiac orifice has a main series of lymphatics along the left gastric artery and also has other lymphatics along the splenic artery, left phrenic artery, esophagus, lesser omentum and diaphragm. The left greater curvature depends on the lymph flow along the splenic artery. The lesser curvature has a main lymphatic stream along the left gastric artery. The right greater curvature has convened lymphatics around pancreatic head. Most streams gather around celiac axis, while the flow along right gastro-epiploic vein is also important. We also studied the relationship between the site of gastric cancer and metastasis is to the lymph nodes in 1097 gastrectomized patients. They had received more than R2 lymphatic dissection successfully. In the cases with lesions located in the upper part of the stomach, n4 (positive findings of metastasis to group 4 lymph nodes) is greater than n3 (positive findings of metastasis to group 3 lymph nodes). We concluded that most of gastric lymphatics run along the proper gastric vessels and gathered around celiac axis. For lymph node dissection in gastric cancer, it is important to know the direction of the gastric lymphatics based on tumor sites. 相似文献

An aggressive pancreatectomy was performed on a 53 year old Japanese man with advanced cancer of the pancreas. The tumor originated from the body of the pancreas and invaded the stomach, duodenum, left kidney, transverse colon and common hepatic artery. An unexpected cancer was also found in the head of the pancreas during the operation. Therefore, total pancreatectomy, total gastrectomy, left adrenonephrectomy, resection of the left transverse colon and dissection of the regional lymph nodes were performed. Resection of the common hepatic artery was also performed, followed by an end-to-end anastomosis between the common hepatic artery and celiac trunk. The postoperative course was uneventful and the patient was doing well until nine months after the operation when multiple metastatic lesions were noted in the liver. He died 391 days after the operation from hepatic failure. 相似文献
