“…None of the previously published cases described ABPDU. 8,9,11,12 Various imaging modalities for preoperative evaluation of choledochal cyst are now available, such as CT, MRCP, ultrasonography, hepatobiliary scan, percutaneous transhepatic cholangiography, and endoscopic retrograde cholangiopancreatography (ERCP). 13 Hepatic duct diverticula can be confused with other cystic lesions such as hepatic cysts, enteric duplication cysts, hepatic artery aneurysm, and duplication anomalies of gall bladder.…”

Hepatic duct diverticulum is a rare form of choledochal cyst that does not fit into the most widely used Todani classification system. Because of its rarity, it may be difficult for clinicians to diagnose and treat it. Here, we present a case of left hepatic diverticulum in a 57-year-old woman with epigastric pain. At presentation, there were mild elevations in the liver function tests. Computed tomography and magnetic resonance cholangiopancreatography showed diverticulum-like cystic lesion with sludge ball near the confluence portion of both intrahepatic bile duct, but the origin of the lesion could not be identified. The clinical impression was type II choledochal cyst. Surgical excision was planned due to recurrent abdominal pain. The operative findings revealed diverticulum arising from left hepatic duct. Histopathology confirmed the lesion to be diverticulum lined by biliary epithelium. The patient had no postoperative complication and no further symptoms since the operation.

“…While its incidence is very low, its true incidence may be difficult to determine because it is generally of no clinical significance and thus requires no specific treatment [4,5]. Eisendrath [6] reported that similar hepatic duct anomalies can be found in 8% of autopsies, indicating that almost all cases must be asymptomatic and are incidental.…”

An extremely rare case of symptomatic right hepatic duct diverticulum located outside the liver

et al. 2005

Symptomatic hepatic duct diverticulum located outside the liver is extremely rare, with only one reported case. We encountered this anomaly and present our experience, focusing on surgical management. A 17-year-old-girl was referred to our institute because of recurrent right upper quadrant pain. At presentation, serum amylase, lipase, bilirubin, and transaminases were normal. White blood cell count and C-reactive protein were slightly raised. Ultrasonography and magnetic resonance cholangiopancreatography (MRCP) revealed a diverticulum-like lesion on the right side of the bile duct system appearing to overlap the gallbladder. The provisional diagnosis was type II choledochal cyst. Pancreaticobiliary malunion (PBMU) could not be confirmed on MRCP. The origin of the lesion could not be identified initially at laparotomy, but after repeated intraoperative cholangiography (IC) studies, the lesion was found to originate from a normal-sized right hepatic duct via a narrow duct. It was relatively easy to ligate the narrow duct and treat the lesion smoothly. IC also showed that the common bile duct was not dilated and that PBMU was absent. Histopathology showed the lesion to be a diverticulum of the bile duct epithelium. This is only the second report of a symptomatic hepatic duct diverticulum located outside the liver. Based on our experience, IC is particularly useful for the complete understanding of anomalous hepatobiliary duct anatomy and for planning surgical treatment.

“…Diverticulum of the common bile duct may undergo spontaneous rupture with formation of retroperitoneal biloma (Takahashi et al 2005). Diverticula have rarely been observed in the hepatic duct (Eisen et al 1963;Jackson and Maxwell 1964;Maxwell et al 1967;Napoli 1970;Down 1974;Meyers et al 1976;Schey et al 1977;Farkas et al 1980;Flowers and Ho 1998;Kaneyama et al 2005a;Hashimoto et al 2007;Fernandes et al 2010). Hepatic duct diverticulum may occur in the common hepatic duct (hepatodochal diverticulum) or in the left or right hepatic duct and is considered to be a developmental anomaly.…”
