A 64-year-old female presented to the surgical emergency unit with a day's history of right upper quadrant pain. Her physical examination revealed right upper quadrant tenderness with no rebound tenderness or muscular guarding. Other systemic findings were normal. Laboratory test showed leukocytosis of 17 × 10³/µL and elevated C-reactive protein of 51 mg/L (0–5 ml/L). Other laboratory values including serum amylase, bilirubin and transaminases were normal. Abdominal ultrasound revealed thickened gallbladder (GB) wall (4.7 mm) with a 25 mm gallstone. A diagnosis of acute calculous cholecystitis was made and intravenous fluid and antibiotic treatment were initiated. Laparoscopic cholecystectomy was considered after 48 h of observation. During surgery a standard 4-port technique was used after pneumoperitoneum using the Veress needle. GB wall was found to be inflamed with omental adhesions. Using the critical view of safety approach, the cystic artery and cystic duct were separately identified, clipped and transected. After careful dissection of the GB from the liver bed small amount of bile was observed oozing from a spot proximal to the ligated cystic duct stump. Irrigation of the spot revealed a small tear at what was thought to be the common hepatic duct. A 5-Fr drainage catheter (50 cm long, 1.4 mm in diameter) was placed into the opened duct and exteriorized through the mid-clavicular 5 mm port site for post-operative drainage. A tube cholangiography done on post-operative Day 7 showed duplication of the common hepatic duct proximal to the cystic duct stump with the injury occurring on the right-sided duct (Fig. ). A magnetic resonance cholangiopancreatography (MRCP) was taken which confirmed the presence of the duplicated common hepatic duct with the cystic duct stump distal to the duplication (Fig. ). No PBM was observed. Her post-operative course was uneventful with an average biliary drainage output of about 300 ml. Drainage tube was clamped on post-operative Day 9 and finally removed 4 weeks after surgery. No complication was observed and patient is currently doing well.
A 54-year-old male presented to a primary care physician with a complaint of indigestion. He underwent gastrofiberscopy, which revealed a small circumferential ulceroinfiltrative ill-defined mucosal lesion at the anterior wall of the antrum. Biopsy specimens were taken from the ulceroinfiltrative lesion, and showed adenocarcinoma. He was diagnosed with gastric cancer and referred to our hospital for an operation. We didn't detect any abnormal findings physically or in the laboratory. Abdominal CT scan showed mild gastric mucosal thickening in the anterior wall of the gastric antrum. We decided to perform laparoscopic assisted distal gastrectomy. During the surgery, we incidentally detected bile leak from the tubular structure around the hepatoduodenal ligament, and therefore converted to open surgery (). We performed intraoperative cholangiogram by cannulizing into the tubular duct, and confirmed that the tubular duct was the accessory bile duct with an ectopic drainage into the stomach, which was connected with the proximal common bile duct and linked with the left intrahepatic duct (). In the specimen, the ACBD was independent of the cancer lesion (). The ACBD was resected afterward. The patient was discharged without complications, and is doing well until now.
