Newest firstIntroduction Situs inversus totalis (SIT) is a rare congenital condition characterized by mirror-image transposition of the thoracic and abdominal viscera. Herein, we report a rare case of laparoscopic common bile duct exploration with choledochotomy and stone extraction in a patient with SIT and a history of total gastrectomy with Roux-en-Y (R-Y) reconstruction. Case presentation A 70-year-old woman with SIT and…
Open article record in new tab ↗Background Absence of portal bifurcation is an extremely rare anomaly that should be recognized preoperatively, especially prior to a major hepatectomy. Case presentation A 45-year-old woman presented with abdominal pain, and abdominal computed tomography (CT) revealed dilatation of both the common bile duct (CBD) and intrahepatic bile duct (IHBD). Endoscopic retrograde cholangiopancreatography (ERCP) showed CBD a…
Open article record in new tab ↗Background An ectopic gallbladder is a rare anomaly and can result in the misinterpretation of imaging findings and clinical confusion. Knowledge of such anomalies facilitates accurate diagnoses and prompt management. We report a pediatric case of an ectopic gallbladder concomitant with congenital biliary dilatation (CBD). Case presentation A 9-year-old girl was referred to our hospital for elevated liver enzyme l…
Open article record in new tab ↗Background Symptomatic congenital biliary dilatation (CBD) during early infancy is always characterized by cystic dilation of the common bile duct with a narrow segment connecting the pancreatic duct. Case presentation In two consecutive infants with a prenatal diagnosis of CBD, we found that biliary sludge had formed in the cyst upon the appearance of symptoms including acholic stool and hypertransaminasemia. Inf…
Open article record in new tab ↗Background Currently, there is an unwavering consensus that the standard surgery for congenital biliary dilation (CBD) is extrahepatic bile duct resection and choledochojejunostomy. However, decades prior, choledochocyst-gastrointestinal anastomosis without extrahepatic bile duct resection (internal drainage surgery, IDS) was preferred for CBD because of its simplicity. Currently, there is almost no chance of a su…
Open article record in new tab ↗Background The presence of a foreign body in the common bile duct (CBD) is a rare phenomenon. Thus, the route and mechanism of its migration remain difficult to fully clarify, especially for cases that occur after gastrectomy with Roux-en-Y reconstruction. Herein, we present a case of a CBD stone that formed around a fish bone as a nidus subsequent to distal gastrectomy with Roux-en-Y reconstruction. Case presenta…
Open article record in new tab ↗Background Endoscopic balloon dilatation (EBD) is the established treatment for common bile duct (CBD) stones. Although pancreatitis and bleeding have been reported as major complications of EBD, balloon-related complications are rarely reported in EBD. Case presentation A 30-year-old woman with suspected CBD stones underwent endoscopic retrograde cholangiopancreatography (ERCP) and EBD. During EBD, the balloon of…
Open article record in new tab ↗Background Mixed adenoneuroendocrine carcinoma (MANEC) of the common bile duct (CBD) is very rare, with only 10 reported cases. Here, we report a case of MANEC of the distal bile duct (DBD) that was surgically resected under a diagnosis of cholangiocarcinoma (CCA). Case presentation A 60-year-old male had epigastric pain and was admitted to our hospital for the treatment of a suspected CBD stone. Upon admission, l…
Open article record in new tab ↗An 82-year-old woman with common bile duct (CBD) dilatation observed during routine ultrasonography was referred to our hospital. Preliminary blood tests revealed elevated levels of hepatobiliary enzymes. Computed tomography (CT) scan showed lower bile duct wall thickening and enhancement. Esophagogastroduodenoscopy revealed mildly swollen papilla of Vater, without ulceration. Endoscopic retrograde cholangiography…
Open article record in new tab ↗Introduction Synchronous double cancer of the gallbladder and pancreas that is associated with congenital biliary dilatation (CBD) and pancreaticobiliary maljunction (PBM) is extremely rare. PBM is frequently reported in Asia, particularly in Japan. We report a surgical case of synchronous double cancer in a patient with primary gallbladder and pancreatic cancer. Presentation of case A 72-year-old woman with epiga…
Open article record in new tab ↗Background Large-cell neuroendocrine carcinoma (LCNEC) of the bile duct is extremely rare and is a high-grade type of neuroendocrine tumor with an aggressive clinical course. Here, we report a case of LCNEC of the extrahepatic bile duct. Case presentation An 80-year-old man presented with severe jaundice. Endoscopic retrograde cholangiography and enhanced computed tomography revealed complete obstruction of the co…
Open article record in new tab ↗We encountered a very rare case of bile duct carcinoma associated with congenital biliary dilatation (CBD) in a 16-year-old female who was admitted to our hospital because of right upper abdominal pain and vomiting. Abdominal computed tomography demonstrated a cystic dilatation of the common bile duct measuring 7 cm in diameter and two enhanced tumors 4 cm in diameter located in the inferior bile duct and middle b…
Open article record in new tab ↗Choledochal cyst (CC)-a congenital anomaly of the bile duct-is rare. We report a 28-year-old woman complaining of epigastralgia who was transferred to our hospital. Physical examination revealed severe tenderness to abdominal palpation without symptoms of diffuse peritonitis. Urgent contrast-enhanced abdominal computed tomography indicated the dilated common bile duct (CBD) was perforated, with a presumed diagnosi…
