Adenomyomatosis is a common tumor-like lesion of the gallbladder. METHODS: A 52-year-old man was admitted to our hospital complaining of right hypochondriac pain and jaundice. Ultrasonography and computed tomography revealed stones in the gallbladder and dilation of the intrahepatic bile ducts. Magnetic resonance cholangiopancreatography revealed narrowing of the common bile duct caused by compression of the gallbladder. Laparotomy revealed type II Mirizzi syndrome. RESULTS: Partial cholecystectomy with a Roux-en-Y hepaticojejunostomy reconstruction was performed. Histologically, Rokitansky-Aschoff sinus proliferation, hypertrophy of smooth muscles, and fibrosis were seen in the gallbladder. A segmental type of adenomyornatosis of the gallbladder was diagnosed. CONCLUSIONS: The pathogenic link between the two peculiar entities is unclear. A possible explanation is considered that the pathogenesis of Mirizzi syndrome is resulted from chronic inflammation due to adenomyomatosis.展开更多

METHOD:We performed a retrospective analysis of the records of 7 patients with Mirizzi syndrome who underwent endoscopic retrograde cholangiopancreatography. RESULTS:The incidence of Mirizzi syndrome was 1.07% of 656 patients given endoscopic retrograde cholangiopan- creatography.Ultrasonography was able to diagnose one case.Endoscopic retrograde cholangiopancreatography suggested the diagnosis in five cases and helped further in the management of these patients.Four patients had cholecystectomy and T-tube placement,and two had cholecystectomy and choledochoduodenostomy.One patient with typeⅠMirizzi syndrome according to the Csendes classification successfully underwent laparoscopic cholecystectomy. CONCLUSIONS:In the study,the incidence of Mirizzi syndrome was 1.07%of patients who underwent endoscopic retrograde cholangiopancreatography. Preoperative diagnosis of Mirizzi syndrome by endoscopicretrograde cholangiopancreatography is important to prevent complications.展开更多

The importance and implications of this condition are related to their associated and potentially serious surgical complications such as bile duct injury, and to its modern management when encountered during laparoscopic cholecystectomy. The pathophysiological process leading to the subtypes of Mirizzi syndrome has been explained by means of a pressure ulcer caused by an impacted gallstone at the gallbladder infundibulum, leading to an inflammatory response causing first external obstruction of the bile duct, and eventually eroding into the bile duct and evolving to a cholecystocholedochal or cholecystohepatic fistula. This article reviews the life of Pablo Luis Mirizzi, describes the earlier and later descriptions of Mirizzi syndrome, discusses the pathophysiological process leading to the development of these uncommon fistulas, reviews the current diagnostic modalities and surgical approaches and finally proposes a simplified classification for Mirizzi syndrome intended to standardize the reports on this condition and to eventually develop a consensual surgical approach to this unexpected and seriously dangerous condition.展开更多

Endoscopic retrograde cholangiopancreatography(ERCP) could serve diagnostic and therapeutic purposes in patients with MS in addition to revealing the relationships between the cystic duct, the gallbladder, and the common bile duct(CBD). Cholecystectomy is a challenging procedure for a laparoscopic surgeon in patients with MS, and the presence of a cholecystocholedochal fistula renders preoperative diagnosis important during ERCP.AIM To evaluate cholecystocholedochal fistulas in patients with MS during ERCP before cholecystectomy.METHODS From 2004 to 2018, all patients diagnosed with MS during ERCP were enrolled in this study. Patients with associated malignancy or those who had already undergone cholecystectomy before ERCP were excluded. In total, 117 patients with MS diagnosed by ERCP were enrolled in this study. Among them, 21 patients with MS had cholecystocholedochal fistulas. MS was further confirmed during cholecystectomy to check if cholecystocholedochal fistulas were present. The clinical data, cholangiography, and endoscopic findings during ERCP were recorded and analyzed.RESULTS Gallbladder opacification on cholangiography is more frequent in patients with MS complicated by cholecystocholedochal fistulas(P < 0.001). Pus in the CBD and stricture length of the CBD longer than 2 cm were two additional independent factors associated with MS, as demonstrated by multivariate analysis(odds ratio 5.82, P = 0.002;0.12, P = 0.008, respectively).CONCLUSION Gall bladder opacification is commonly seen in patients with MS with cholecystocholedochal fistulas during pre-operative ERCP. Additional findings such as pus in the CBD and stricture length of the CBD longer than 2 cm may aid the diagnosis of MS with cholecystocholedochal fistulas.展开更多

This obstruction may worsen and thus result in cholecystobiliary fistula. Surgical management of Mirizzi syndrome is complicated by the presence of inflamed tissue around the hepatic pedicle, making it impossible to distinguish between the main bile duct and the gallbladder. The surgeon＇s first task is to perform subtotal cholecystotomy（from the fundus of the gallbladder to the neck） without trying to locate the cystic duct. In a second step, the gallstones are extracted and the main bile duct is then repaired. In most cases, a T-tube is used to drain the main bile duct, and abdominal drainage is left in place（in case a bile fistula forms）. This study concluded that preoperative drainage of the main bile duct in the treatment of Mirizzi syndrome types II and III is feasible and might help to decrease the postoperative complication rate.展开更多
