A 63-year-old woman from rural Nepal presented with a history of right upper abdominal pain, epigastric discomfort, bloating, and dyspepsia for 4 years, followed by intermittent fever and jaundice for a month. She had an increase in severity of pain, yellowish discoloration of body, vomiting, and fever for 1 week but had no history of anorexia or weight loss. She had no significant past medical and surgical history. On general examination she had icterus. Her vital parameters were within the normal range. An examination of her abdomen revealed a non-distended soft abdomen with negative Murphy’s sign and her gall bladder was not palpable.\nBiochemical parameters showed hemoglobin 13.4 gm/dl, total leukocyte count 12,600/mm3, platelets 158,000/mm3, total bilirubin 7.9 mg/dl, direct bilirubin 5.4 mg/dl, alanine aminotransferase (ALT) 196 U/L, aspartate aminotransferase (AST) 146 U/L, alkaline phosphatase (ALP) 273 U/L, serum amylase 50 U/L, and lipase 100 U/L. An abdominal ultrasonogram showed multiple calculi in her gallbladder (largest 6 mm), dilated common bile duct (CBD) measuring 13 mm with dilated intrahepatic biliary ducts (IHBDs), and suspected calculi/mass in distal CBD. A contrast-enhanced computed tomography (CECT) scan of her abdomen revealed similar findings and could not differentiate mass or stone in distal CBD. Endoscopic retrograde cholangiopancreatography (ERCP) was planned with the aim of extracting the stone and, if present, a biopsy from the mass. ERCP was unsuccessful on account of difficult anatomy. Magnetic resonance cholangiopancreatography (MRCP) reported the following: IHBDs from the right lobe of the liver drained into the right hepatic duct that formed a separate CBD with the cystic duct opening into it; the IHBDs from the left lobe of the liver drained into the left hepatic duct that formed a separate CBD. Both CBDs appeared mildly dilated proximally and descended separately until a point where a stone was noted. Below this point, the CBD could not be traced so the type of anomaly was inconclusive (Fig. ).\nDue to radiological findings that were suspicious of double CBD (DCBD), our patient was then planned for exploratory laparotomy to assess and confirm the radiological findings, and for definitive diagnosis and treatment of the condition. Intraoperative findings were contracted gall bladder with multiple tiny calculi, two separate draining bile ducts, which were fused just before opening to the ampulla, common duct with a calculus of 1 × 1 cm2, and cystic duct opening into the right duct (Fig. ). So the diagnosis of type Va DCBD with cholelithiasis and choledocholithiasis was made. Following this, cholecystectomy was done, the common duct was explored and the stone was extracted. The right duct was divided just proximal to the opening of the cystic duct and the left duct was also divided at the same level. After closing distal common bile duct stump, reconstruction was done by hepatic ductoplasty (joining two ducts) with hepaticojejunostomy in Roux-en-Y fashion. Her postoperative period was uneventful and she was discharged after 1 week and was doing well at 6-month follow-up.\nHistologic examination of the resected specimens revealed chronic inflammatory changes in the gallbladder and common bile duct with no evidence of malignancy.
A 77-year-old woman presented to the outpatient department of our hospital complaining of recurrent epigastric pain.\nPatient’s symptoms started a month ago with recurrent episodes, with no history of fever, chills, or vomiting.\nThe patient had a history of laparoscopic cholecystectomy for cholelithiasis 2 years earlier at another hospital. She had undergone endoscopic retrograde cholan-giopancreatography (ERCP) twice for choledocholithiasis before undergoing cholecystectomy.\nThe patient did not have a history of drinking or smoking. There was no remarkable family medical history.\nPhysical examination did not reveal tenderness or signs of peritoneal irrigation, and the bowel sounds were normal. At the outpatient clinic, her temperature was 36.7 °C, pulse rate was 70 beats/min, and blood pressure was 122/82 mm Hg.\nBlood analysis showed normal complete blood cell count, liver function test and C-reactive protein.\nComputed tomography (CT) imaging revealed a dilated CBD that harboured multiple choledocholithiasis (Figure ). After admission, ERCP was subsequently performed, and the stones were extracted using a Dormia basket (MTW Endoskopie, Wesel, Germany) (Figure ) after endoscopic papillary balloon dilatation by a CRETM balloon dilatation catheters (Boston Scientific Corporation, Natick, MA, United States). A 5 Fr endoscopic nasobiliary drainage (ENBD) catheter (ENBD-5, Cook Medical, Bloomington, IN, United States) was inserted at the end of the procedure. A day after the ERCP, tubography via the ENBD catheter was performed to confirm the presence of residual stones in the bile duct. However, no definite filling defects were observed on tubography (Figure ). The patient was discharged without any complications of ERCP. A day after discharge, she visited the emergency department with complaints of severe epigastric pain and fever. Her temperature was 38.2 °C, pulse rate was 79 beats/min, and blood pressure was 149/85 mm Hg. Laboratory findings were suggestive of cholestasis [aspartate aminotransferase, 210 U/L (normal: 0–35 U/L); alanine aminotransferase, 134 U/L (0-35); alkaline phosphatase, 201 U/L (30-120); gamma glutamyl transferase, 184 U/L (9-64); total bilirubin, 2.77 mg/dL (0.3-1.2); direct bilirubin, 1.32 mg/dL (0-0.2); and C-reactive protein 6.91 mg/dL]. A CT scan demonstrated another dilated extrahepatic bile duct draining the right lobe of the liver, which also contained stones in the distal portion (Figure ). An urgent ERCP was performed as the stones were impacted at the ampulla (Figure ), and the stones with pus were retrieved using a balloon catheter (Escort II® Double Lumen Extraction Balloon, Cook Medical, Bloomington, IN, United States). A 10 Fr, 5 cm endoscopic retrograde biliary drainage tube (Cotton-Leung Biliary Stent, Cook Medical, Bloomington, IN, United States) was then placed in the CBD.\nMagnetic resonance cholangiopancreatography (MRCP) was performed to evaluate the delicate structures of the CBD and to check for any remnant stones. MRCP revealed DCBD independently draining the left and right lobes of the liver, that created a short segment intrapancreatic CBD (Figure ) without a communicating channel, that was consistent with the DCBD Type Va as classified by Choi et al[,]. Residual choledocholithiasis was also noted in the right CBD. There was no evidence of anomalous union of the pancreaticobiliary duct on MRCP.
