肝内外胆管结石的微创治疗策略

肝内外胆管结石是一种常见、多发疾病,其传统的开腹手术近年来受到微创手术的挑战.本文通过文献检索,结合作者的实践经验,在全面总结肝内、外胆管结石的微创治疗现状基础上,探讨出一种可有效提高其微创治疗效果的策略:(1)对于肝内胆管结石:可根据指征选用腹腔镜肝切除、腹腔镜胆总管探查取石术(laparoscopic common bile duct exploration,LCBDE)、经皮经肝胆道镜取石术;(2)对于胆囊结石合并胆总管结石:可根据指征选用腹腔镜胆囊切除(laparoscopic cholecystectomy,LC)+经内镜十二指肠乳头括约肌切开(endoscopic sphincterotomy,EST)或经内镜乳头气囊扩张术(endoscopic papillary balloon dilatation,E P B D)、L C+经胆囊管胆总管探查取石术(laparoscopic transcystic common bile duct exploration,LTCBDE)、LC+LCBDE+T管引流或一期缝合术;(3)对于肝内合并肝外胆管结石,可根据指征选用腹腔镜肝切除、经肝断面胆管胆道镜取石、LCBDE、EST、经皮经肝胆道镜碎石术.根据上述策略,结合术者的技术和设备条件,合理选择微创治疗方法,对于提高肝内、外胆管结石的治疗效果具有重要意义.

Cystic duct directly joining the main pancreatic duct

A unique anomaly of the direct union between the cystic duct and the main pancreatic duct is presented. A 19-year-old man with a history of repeated epigastralgia underwent endoscopic retrograde cholangiopancreaticography that showed a direct union between the cystic duct and the main pancreatic duct. No pancreaticobiliary maljunction was noticed. Cholecystectomy accompanied by resection of the long cystic duct was performed. The excised gallbladder showed cholesterolosis, chronic cholecystitis, and hyperplasia of the pseudopyloric glands microscopically. The patient has been well for 3 years since surgery.

New cannulation method for pancreatic duct cannulation-bile duct guidewire-indwelling method

The patient was a 58-year-old male with symptomatic alcoholic chronic pancreatitis.Since a 10 mm calculus was observed in the pancreatic body and abdominal pain occurred due to congestion of pancreatic juice,endoscopic retrograde cholangiopancreatography was conducted for assessment of the pancreatic duct and treatment of pancreatic calculus.Pancreatogram was slightly and insuff iciently obtained by injecting the contrast media via the common channel of the duodenal main papilla.We tried to cannulate selectively into the pancreatic duct for a clear image.However,the selective cannulation of the pancreatic duct was difficult because of instability of the papilla.On the other hand,selective cannulation of the bile duct was relatively easily achieved.Therefore,after the imaging of the bile duct,a guidewire was retained in the bile duct to immobilize the duodenal papilla and cannulation of the pancreatic duct was attempted.As a result,selective pancreatic duct cannulation became possible.It is considered that the bile duct guidewire-indwelling method may serve as one of the useful techniques for cases whose selective pancreatic duct cannulation is diff icult("selective pancreatic duct diff icult cannulation case").     

Adaptative bile duct proliferative response in experimental bile duct ischemia

BACKGROUND/AIMS: A rat model of bile duct ischemia was established and used to examine the potential of bile duct proliferation to provide an adaptative response in cholestatic disorders. METHODS: Rats underwent partial or complete arterial deprivation of the liver. Serum biochemical tests, histological analyses and bile secretion measurements were performed at different time points up to 6 weeks after surgery. RESULTS: Rats developed biochemical signs of cholestasis exclusively after complete arterial deprivation. Within 4h, cholangiocytes in these rats showed morphological signs of cell damage. After 48h, they displayed VEGF expression and became proliferative. The proportion of Ki67-labeled cholangiocytes ( approximately 30%) was similar in interlobular bile ducts and periportal ductules. A ductular reaction made of well-formed bile ducts confined to portal tracts developed within 1 week. Bile flow which was initially decreased, was restored at 3 weeks, while the biochemical signs of cholestasis completely resolved at 6 weeks. At this time, the number of bile duct sections was maximal. Fibrosis intensity was also maximal, although moderate (相似文献   

A case of cholecystohepatic duct with atrophic common hepatic duct

BackgroundCholecystohepatic ducts are rare congenital variants of the biliary tree.Case outlineAn 81-year-old woman presented with biliary colic and elevated liver function tests. An ERCP demonstrated a common bile duct stone and stricture of the common hepatic duct. An operative cholangiogram demonstrated an atrophic common hepatic duct and retrograde filling of the gallbladder through a large cholecystoheptic duct. The patient had a cholecystectomy and reconstructive cholecystohepatic duct jejunostomy.DiscussionThis case demonstrates a rare congenital anomaly where the gallbladder fills retrograde during an intraoperative cholangiogram despite clipping of the cystic duct. The major path of biliary drainage was through a large cholecystoheptic duct similar to a gallbladder interposition; however, the common hepatic duct was still present but atrophic. This anomaly has not been described previously.     

Bile duct disorders

Drug-induced bile duct injury related prolonged or chronic cholestasis is recognized as a common side effect of treatment with several drugs. The severity and duration of the clinical symptoms suggest that this increase in number of reports is not only related to clinician and pathologists being increasingly aware of the condition, but also may represent a true increase in incidence likely related to a time-related growing experience with newer drugs. This clinical presentation encompasses a wide variety of features that may be the source of diagnostic difficulties, especially in the cases where cholestasis occurs days or weeks after the completion of therapy. Even more puzzling is the initial picture of hepatocholangitis, which may be silent and ensuing bile duct paucity with chronic anicteric cholestasis may be another source of diagnostic difficulties in the long-term. These diagnostic difficulties suggest that some of the cases of the so-called "idiopathic adulthood ductopenia" may originate from overlooked drug induced vanishing bile duct syndrome. The pathogenesis of the syndrome remains largely unknown and the determinants of prognosis and outcome. From reproducible data obtained in different studies investigating HLA-dependent predisposition, one may assume that genetics plays a major role even if other unknown additive factors are also likely involved. Severity of initial hepatocholangitis is likely to represent another important determinant of severity and prognosis, however to be assessed in larger longitudinal studies. Therapy of large bile duct injury mimics that of primary sclerosing cholangitis. Treatment of small bile duct injury remains disappointing. Corticosteroids are invariably ineffective. Ursodeoxycholic acid as been shown to induce improvement of clinical and biochemical cholestasis in some selected cases, its efficacy being however unpredictable. Preliminary data about the natural history of the vanishing bile duct syndrome suggest that therapy might be more effective when initiated early.
