The patterns with metastasis of primary gallbladder carcinoma in lymph nodes and liver were examined histopathologically and classified as TNM staging of the American Joint Committee on Cancer.RESULTS: Of the 45 patients, 29 (64.4%) had a lymph node positive disease and 20 (44.4%) had a direct invasion of the liver. The frequency of involvement of lymph nodes was strongly influenced by the depth of the primary tumor(P = 0.0001). The postoperative survival rate of patients with negative lymph node metastasis was significantly higher than that of patients with positive lymph node metastasis (P = 0.004), but the postoperative survival rate of patients with N1 lymph node metastasis was not significantly different from that of patients with N2 lymph node metastasis (P = 0.3874). The postoperative survival rate of patients without hepatic invasion was significantly better than that of patients with hepatic invasion (P= 0.0177).CONCLUSION: Complete resection of the regional lymph nodes is important in advanced primary gallbladder carcinoma (PGC). The initial sites of liver spread are located mostly in segments Ⅳ and V. It is necessary to achieve negative surgical margins 2 cm from the tumor. In patients with hepatic hilum invasion, extended right hepatectomy with or without bile duct resection or portal vein resection is necessary for curative resection.展开更多

Keywords used included accessory liver lobe,aberrant liver tissue, ectopic liver tissue, ectopic liver nodule, heterotopic livertissue, hepatic choristoma, heterotopic liver tissue on the gallbladder, and ectopicliver tissue on the gallbladder. The search included articles published before June2020 with no language restriction. Letters to the editor, case reports, reviewarticles, original articles, and meeting presentations were included in the search.Articles or abstracts containing adequate information on age, sex, history of liverdisease, preliminary diagnosis, radiologic tools, lesion size, surgical indication,surgical procedure, and histopathological features of ectopic liver tissue wereincluded in the study.RESULTS A total of 72 articles involving 91 cases of ectopic liver tissue located on the gallbladder surface or mesentery were analyzed. Of these 91 patients, 62 werefemale and 25 were male (no gender available for 4 patients), and the age rangewas 5 d to 91 years. Forty-nine patients underwent surgery for chroniccholecystitis or cholelithiasis, and 14 patients underwent surgery for acutecholecystitis. The remaining 28 patients underwent laparotomy for other reasons.Cholecystectomy was laparoscopic in 69 patients and open in 11 patients. Theremaining 19 patients underwent various other surgical procedures such asautopsy, liver transplantation, living donor hepatectomy, Whipple procedure, andliver segment V resection. Histopathologically, hepatocellular carcinoma wasdetected in the ectopic liver tissue of one patient.CONCLUSION Ectopic liver tissue is a rare developmental anomaly which is usually detectedincidentally. Although most studies suggest that ectopic liver located outside thegallbladder has a high risk of hepatocellular carcinoma, this is not reflected instatistical analysis.展开更多

The major complication and mortality rate were about 2-4% and 0.01-0.33% respectively. Arterio-portal fistula as a complication of percutaneoos liver biopsy was infrequently seen and normally asymptomatic. Hemobilia, which accounted for about 3% of overall major percataneous liver biopsy complications, resulted rarely from arterioportal fistula We report a hemobilia case of 68 years old woman who was admitted for abdominal pain after liver biopsy. The initial ultrasonography revealed a gallbladder polypoid tumor and common bile duct (CBD) dilatation. Blood clot was extracted as endoscopic retrograde cholangiopancreatography (ERCP) showed hemobilia. The patient was shortly readmitted because of recurrence of symptoms. A celiac angiography showed an intrahepatic artedo-portal fistula. After superselective embolization of the feeding artery, l^e patient was discharged uneventfully. Most cases of hemobilia caused by percutaneous liver biopsy resolved spontaneously. Selective angiography embolization or surgical intervention is reserved for patients who failed to respond to conservative treatment.展开更多

The primary antibodies including anti-chromogranin A, gastrin, serotonin, insulin, somatostatin, gastrin, pancreatic polypeptide, adreno- corticotropic hormone (ACTH), calcitonin, bombesin, β-human chorionic gonadotropin (β-HCG) were employed to identify the property of tumors.ResultsIn one cases tumor of neuroendocrine carcinoma. In the other two cases tumor were typical carcinoid. In immunohistochemistry study, the tumor cells showed positive reaction to chromagranin A and contained positive cells of gastrin, serotonin, insulin and pancreatic polypaptide. Electronmicroscopy showed the cytoplasm contained dense round granules.ConclusionThe Nuroendocrine tumor of liver and gallbladder is a special type neoplasm with character of histology, immunohistochemistry and electron microscopy.

A male patient in his 70 s was diagnosed with advanced gallbladder cancer directly infiltrating the right hepatic duct(RHD), together with RSLT. Preoperative three-dimensional simulation of the liver based on multiple detector computed tomography images after cholangiography revealed ramifications of all segmental portal veins from the portal trunk and discordance of the arterial and biliary branching patterns of segment 8. Fusion analysis of the biliary architecture and segmental volumetry showed that the RHD drained segments 1 r, 5, 6, and 7. We successfully performed a modified right-sided hepatectomy sparing segment 8(i.e., resection of the RHD drainage territory), with negative surgical margins. This report is the first to describe major hepatectomy for advanced gallbladder cancer with RSLT.展开更多

METHODS: We reported herein the case of a 29-year-old man with a left liver tumor in whom left lateral bisegmen- tectomy was mandatory. It represents the first description of a sinistroposition of both gallbladder and common bile duct. RESULTS: Surgical exploration revealed a left-side gall- bladder , located under the left lobe of the liver. During he- patic parenchyma dissection at the left side of the round liga- ment and the Rex recessus, the common bile duct was in- jured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the Rex recessus before reaching the hepatoduo- denal ligament. CONCLUSION: Only careful dissection of the hepatoduo- denal ligament up to Rex recessus level prior to liver paren- chyma resection could avoid biliary tract injury during left lobectomy.展开更多
