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

The frequency of PBM in GBC patients and the clinical features of GBC patients with PBM vary in different studies. DATA SOURCES: English-language articles describing the association between PBM and GBC were searched in the PubMed and Web of Science databases. Nine case-control studies fulfilled the inclusion criteria and addressed the relevant clinical questions of this analysis. Data were extracted independently by two reviewers using a predefined spreadsheet. RESULTS: The incidence of PBM was higher in GBC patients than in controls (10.60% vs 1.76%, OR: 7.41, 95% CI: 5.03 to 10.87, P<0.00001). The proportion of female patients with PBM was 1.96-fold higher than in GBC patients without PBM (80.5% vs 62.9%, OR: 1.96, 95% CI: 1.09 to 3.52, P=0.12). GBC patients with PBM were 10 years younger than those without PBM (SMD: -9.90, 95% CI: -11.70 to -8.10, P<0.00001). And a difference in the incidence of associated gallstone was found between GBC patients with and without PBM (10.8% vs 54.3% OR: 0.09, 95% CI: 0.05 to 0.17, P<0.00001). Among the GBC patients with PBM, associated congenital dilatation of the common bile duct was present with a higher incidence ranging from 52.2% to 85.7%, and 70.0%-85.7% of them belonged to the P-C type of PBM (the main pancreatic duct enters the common bile duct). No substantial heterogeneity was found and no evidence of publication bias was observed.CONCLUSIONS: PBM is a high-risk factor for developing GBC, especially the P-C type of PBM without congenital dilatation of the common bile duct. To prevent GBC, laparoscopic cholecystectomy is highly recommended for PBM patients without congenital dilatation of the common bile duct, especially relatively young female patients without gallstones.展开更多

METHODS:In this cross-sectional study,autopsies were performed on 253 cadavers of more than 13 years old.The cadavers were studied to determine the number,location of stone formation,chemical composition,dry weight,and mean diameter of stones in the gallbladder and common bile duct. RESULTS:The prevalence of gallstone disease in these cadavers was 6.3%(men 4.7%,women 8.6%,not significantly different,P=0.216).There was a positive relationship between the age and prevalence of gallstone disease(P=0.033).The most common stone compositions were cholesterol and oxalate.The mean diameter (P=0.0058)and dry weight(P<0.0001)of stones were higher in the gallbladder than in the common bile duct. Positive relations between the amount of oxalate and mean diameter,and between the amount of oxalate and mean dry weight of gallstones were found,but the relationship between the amount of cholesterol and mean diameter was inverse. CONCLUSIONS:The prevalence of gallstones differed among age groups.Diameter and dry weight of gallstones were dependent on location of stone formation and chemical composition.展开更多
