Endoscopic treatment of extrahepatic bile duct strictures in patients with portal biliopathy carries a high risk of haemobilia: report of 3 cases

Extrahepatic portal venous obstruction can be associated with bile duct abnormalities, the entity being called portal biliopathy. Three cases are reported of extrahepatic bile duct strictures in patients with portal biliopathy who developed haemobilia during endotherapy. Although endoscopic therapy with stent placement can be successful in patients with portal biliopathy and could also lead to permanent stricture resolution, procedure-related haemobilia is not as uncommon as previously held. Shunt surgery could be a better option in fit patients, since it could provide definitive treatment in a young patient with an otherwise normal life expectancy.     

Double cancers in the common bile duct: molecular genetic findings with an analysis of LOH

We report a 69‐year‐old man with double cancers in the common bile duct. One cancer was located between the superior and middle parts of the bile duct, while the other cancer was in the inferior part of the bile duct. Pylorus‐preserving pancreatoduodenectomy was performed. There was no communication between the two cancers in either the mucosal layer or the subepithelial layer. On pathological examination, the upper cancer was diagnosed as poorly differentiated adenocarcinoma, while the lower one was found to be moderately differentiated adenocarcinoma. We analyzed loss of heterozygosity (LOH), using microsatellite markers on five chromosomal arms, in both the upper and the lower cancers. Both cancers showed common regions of LOH at 5q, 6q, 9p, 17p, and 18q, whereas the upper cancer showed one additional region of LOH at 8p, thus suggesting progression, due to the acquisition of the additional LOH, in the upper cancer. No LOH was observed in the region between the two cancers. The presence of one additional LOH in the upper cancer suggests that the upper cancer was a metastasis of the lower one.     

两种手术方法处理腹腔镜胆囊切除术后胆总管残余结石患者临床疗效比较

目的 分析比较经内镜逆行性胰胆管造影（ERCP）下取石与开腹胆道探查（CBDE）治疗腹腔镜胆囊切除术（LC）后胆总管残余结石患者的临床疗效。方法 2015年2月~2016年12月我院收住的经LC术后存在胆总管残余结石患者84例,其中38例采取CBDE法（A组）治疗,46例采取ERCP下取石（B组）。结果 B组术中出血量明显少于A组[（3.4±1.3）ml对（124.2±65.8）ml,P<0.05],手术时间[（34.8±4.2）min对（123.3±15.8）min,P<0.05]、术后排气时间[（1.0±0.7）h对（42.6±9.1）h,P<0.05]和住院时间[（4.9±3.5）d对（9.3±4.3）d,P<0.05]均明显短于A组;术后1 w,B组血清GGT水平为（63.7±7.5）IU/L,与A组的（70.2±7.9）IU/L 比无显著性相差（P>0.05）,血清ALP水平为（105.6±11.5）IU/L,与A组的（115.4±12.8）IU/L比无显著性相差（P>0.05）;A组并发症发生率为23.7%、结石再复发率为5.3%,而B组分别为15.2%和6.5%,两组比较无显著性差异（P>0.05）。结论 相对于CBDE术,采用ERCP下取石处理经LC术后胆总管残余结石患者可有效降低术中出血量,缩短手术时间,并因可反复进行而具有优势。
