A case of spontaneous perforation of the common bile duct associated with cholangitis]

Spontaneous perforation of the common bile duct (CBD) is a rare event in adults. Most cases of CBD perforation are iatrogenic after invasive procedures such as endoscopic retrograde cholangiopancreatography (ERCP) or cholecystectomy. We report a case of an 81-year-old woman who presented with severe right upper abdominal pain, fever, and chills. Abdominal CT showed multiple gallbladder and CBD stones and loculated fluid collection in the inferoposterior portion of the stomach. ERCP showed the leakage of contrast media into the peritoneal cavity from the CBD. We performed endoscopic sphincterotomy (EST) and endoscopic nasobiliary drainage (ENBD) to decompress the CBD instead of emergent surgical intervention. One week later, cholangiography via ENBD tube revealed that there was no more leakage of the contrast media from the CBD. We performed cholecystectomy, removal of the CBD stones after exploration of the CBD, and T tube insertion. The perforated site of the CBD was closed and there was no more fluid collection in the inferoposterior portion of the stomach. Medical treatment including endoscopic procedures was useful for healing of the perforated CBD.

Biliary tuberculosis causing cicatricial stenosis after oral anti-tuberculosis therapy

A 36-year-old Philippine woman presented with dark urine and yellow sclera. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed dilatation of the intrahepatic bile ducts and also showed an irregular stricture of the common hepatic duct at the liver hilum. Histological examination of biopsies from the bile duct revealed epithelioid cell granulomas and caseous necrosis. Tubercle bacilli were then detected on polymerase chain reaction (PCR) testing of the bile, giving the diagnosis of biliary tuberculosis. Although microbiological cure was confirmed, the patient developed cicatricial stenosis of the hepatic duct. She underwent repeated treatments with endoscopic biliary drainage (EBD) tubes and percutaneous transhepatic biliary drainage (PTBD) tubes, and the stenosis was corrected after 6 years. We present a case of tuberculous biliary stricture, a condition that requires careful differentiation from the more common malignancies and needs long-term follow-up due to the risk of posttreatment cicatricial stenosis, although it is rare.     

ERCP在老年胆胰疾病治疗中的临床应用

目的探讨逆行胰胆管造影术(ERCP)在老年胆胰疾病患者治疗中的应用价值及安全性。方法对2000年1月～2006年10月在我院收治的32例70岁以上的胆胰管疾病患者进行回顾性分析。结果32例老年患者行ERCP治疗36例次,成功率100%。进行单纯EST2例,EST加ENBD2例,EST加取石术19例(23例次),EST加取石术及ENBD2例,ENBD5例,ERBD2例。本组发生内镜有关的并发症4例,无死亡病例。术后各项指标与术前相比有明显好转。结论对胆胰疾病的老年患者行ERCP治疗具有创伤小、安全性好、并发症少、疗效确切等优点,值得临床推广应用。

A Case of Post-Laparoscopic Cholecystectomy Bile Leakage from the Cystic Duct Treated by Endoscopic Nasobiliary Drainage without EST

Abstract: The patient was a 45 year old female with cholelithiasis who had undergone laparoscopic cholecystectomy. Bile leakage was detected from the site of Penrose drain insertion immediately after the operation. As no improvement of bile leakage was subsequently observed, ERCP (endoscopic retrograde cholangiopancreatography) was performed on the third postoperative day. Neither choledocholithiasis nor choledochal stricture was found and the diagnosis of bile leakage from the cystic duct stump was made. A 5Fr ENBD (endoscopic nasobiliary drainage)-tube without EST (endoscopic sphincterotomy) was inserted into the common bile duct, and bile leakage disappeared completely on the third day after insertion of the ENBD tube. Additional laparotomy, EST or biliary stenting was thereby avoided. Choledo-chography, via the ENBD-tube, showed no leakage of contrast material, the ENBD-tube was removed and the patient was discharged. ENBD should be considered as a method of treatment for management of bile leaks from the cystic duct stump.

A case of percutaneous and transpapillary placements of expandable metallic stents in a patient with cholangiocarcinoma at the hilum of the liver

A 76-year-old woman was admitted with obstructive jaundice. US and MR cholangiopancreatography (MRCP) revealed an inoperative cholangiocarcinoma, 3 cm in diameter at the hilum of the liver, the obstruction of the hepatic duct bifurcation and the separation of bilateral hepatic bile ducts. Percutaneous transhepatic biliary drainage (PTBD) was performed from bilateral hepatic bile ducts. The right PTBD tube was spontaneously extubated. We could not succeed in performing internal biliary drainage across the hilar malignant stricture from a left hepatic bile duct, because of bad angulation. Transpapillary insertion into the common bile duct (CBD) was extremely difficult due to the collapse of the CBD. Endoscopic sphincterotomy (EST) after precutting method was performed. Although we performed the ballooned dilatation of malignant stricture and the insertion of a self-expandable metallic stent (EMS) into a right hepatic bile duct transpapillary. After dilatation of the hilar malignant stricture by the initial EMS, we inserted a guidewire into the CBD through the wire mesh of a stent from the left PTBD tube. We could insert the second EMS from a left hepatic bile duct to the CBD transhepatically, using a dilator and a dilating balloon. Finally, we performed the ballooned dilatation from bilateral hepatic bile ducts to the CBD transpapillary. She was discharged after bilateral internal biliary drainages, successfully.

Anatomical variations of the cystic duct： Two case reports

Anatomical variations of the cystic duct often occur and may be encountered during cholecystectomy. Knowledge of the variable anatomy of the cystic duct and cysticohepatic junction is important to avoid significant ductal injury in biliary surgery. Here, we present two unusual cases with an anomalous cystic duct, namely, low lateral insertion and narrow-winding of the cystic duct. The first case was a 64-year-old man with cholelithiasis and chronic cholecystitis. During surgery, the entrance of the cystic duct was misidentified as being short and leading into the right hepatic duct. Further exploration showed multiple calculi in the right and common hepatic ducts. Cholecystectomy was completed, followed by T-tube drainage of the common and right hepatic ducts. Postoperative T-tube cholangiography demonstrated that the two T tubes were respectively located in the cystic and common hepatic duct. Six weeks later, the retained stones in the distal choledochus were extracted by cholangioscopy through the sinus tract of the T-tube. The second case was a 41-year-old woman, in which, preoperative endoscopic retrograde cholangiopancreatography （ERCP） revealed a long cystic duct, with a narrow and curved-in lumen. The patient underwent open cholecystectomy. Both patients were cured. The authors propose that preoperative ERCP or magnetic resonance cholangiopancreatography （MRCP）, and intraoperative cholangiography or cholangioscopy constitute a useful and safe procedure for determining anatomical variations of the cystic duct.

目的：探讨经内镜逆行胰胆管造影(ERCP)在诊断和治疗肝移植患者胆道远期并发症中的应用。方法：肝移植术后出现胆道远期并发症患者6例，共行ERCP 12次，根据患者的情况进行扩张、内镜下乳头切开取石、内支架置入等治疗。结果：1例胆总管结石行乳头切开后取石成功，1例胆道狭窄在胆道扩张后胆道梗阻症状解除，4例胆道狭窄合并胆总管结石的狭窄近端结石经乳头切开取出，狭窄远端结石行胆道扩张、内支架置入等治疗后取出。所有患者经治疗后胆红素、碱性磷酸酶等酶学指标均有不同程度的下降，无严重并发症发生。结论：ERCP是诊断和治疗肝移植患者胆道远期并发症安全、有效的手段。     

经内镜胆道引流治疗胆道梗阻

目的：进一步提高经内镜胆道引流术的成功率。方法：总结1998年1月至2001年9月对320例胆道梗阻患者行十二指肠镜下各种胆道引流术的经验，其中鼻胆管引流术（ENBD）242例，胆道内置管引流术（ERBD）43例，胆道金属支架术（EMBE）35例。结果：305例得到成功引流，胆道梗阻症状缓解；失败15例。其中ENBD失败10例，经调整鼻胆管位置或重新置管获得成功；ERBD失败3例，2例选用合适长度的支架后引流成功，1例经努力仍未成功改用经皮肝穿刺胆道引流；EM-BE失败2例，其中1例金属支架未超出肿瘤狭窄段，经原金属支架再套入另一金属支架而成功，另1例支架放置1月又出现胆道阻塞，经原金属支架通道再放入塑料支架而恢复通畅引流。结论：经内镜引流治疗胆道梗阻疗效确切，及早分析内镜引流失败原因并采取相应的对策，绝大多数引流失败是可以避免或补救的。     

经内镜鼻胆管引流术在腹腔镜胆管探查中的作用

目的：应用经内镜鼻胆管引流术(ENBD)作为腹腔镜胆管探查术(LCBDE)胆管引流方式，探讨其应用价值。方法：对拟行腹腔镜下胆管探查的患者术前进行ENBD，后经胆总管探查切口应用液电碎石、胆道镜取石，将肝内外胆管结石取净，保留鼻胆管于胆管内，将胆总管探查切口一期缝合，常规放置腹腔引流管。术后经鼻胆管造影，肝内外胆管无残余结石，无胆漏，择期拔除腹腔引流管及鼻胆管。结果：共43例患者术前行ENBD，平均6．1d后行LCBDE。36例(83.7％)患者成功进行LCBDE，胆管探查切口一期缝合。术后经鼻胆管造影，发现1例(2．6％)术中胆道镜漏诊--小结石，经内镜取石后痊愈；无胆管狭窄及胆漏等并发症发生。另有7例患者(18．6％)中转开腹手术，其中2例保留鼻胆管，胆管切口行一期缝合，术后顺利拔除鼻胆管。38例患者(88．4％)均成功应用：ENBD进行胆管引流，平均3．2d拔除腹腔引流管，6.7d拔除鼻胆管，无相关并发症发生。结论：ENBD作为LCBDE胆管引流，是安全有效的方式，且术后引流时间短，并发症少，可充分发挥出腹腔镜治疗胆管结石微创的优势。

ENBD tube placement prior to laparoscopic cholecystectomy may reduce the rate of complications in cases with predictably complicating biliary anomalies

Background  

The risk factors predisposing to bile duct injury or postoperative bile leakage associated with laparoscopic cholecystectomy (LC) include the presence of an accessory hepatic duct, the anomalous cystic duct confluence, and duct of Luschka. One method to prevent bile duct injury is preoperative placement of an endoscopic nasobiliary drainage tube (ENBD assisted LC). The aims of this investigation are first, to report the incidence of bile duct anomalies according to the classification system proposed by Wakayama Medical University and second, to evaluate the efficacy of ENBD assisted LC with regard to prevention of intraoperative bile duct injury and postoperative bile duct injury or leakage.     

Intrahepatic subcapsular biloma after endoscopic retrograde cholangiopancreatography treated by endoscopic biliary drainage

Several major complications from endoscopic retrograde cholangiopancreatography (ERCP), including pancreatitis, cholangitis, and hemorrhage have been discussed in detail; however, a few uncommon but severe complications have been reported. We encountered an unusual case of post-ERCP intrahepatic subcapsular biloma. An 89-year-old woman with a 25-mm mass located at the hepatic hilum, suggestive of cholangiocarcinoma, underwent ERCP which demonstrated complete stricture of the common hepatic duct. Subsequently, two plastic stents were placed from the common bile duct to the right and left intrahepatic branches. On day 3, serum inflammatory markers were elevated and computed tomography revealed a large subcapsular fusiform fluid collection in the right liver, consistent with biloma. On day 6, the biloma ruptured and 500 ml of biliary ascites were removed. On day 8, endoscopic nasobiliary drainage via the right intrahepatic branch was performed because of recurrence of biliary ascites. After the procedure, 150 ml of bile was collected through the drain every day and no ascites recurred. We believe that minor injury to the right intrahepatic bile duct due to guidewire manipulation caused the biloma. Biloma may become apparent several days after ERCP, and endoscopic biliary drainage placement adjacent to the bile duct rupture site can stop bile leakage.
