Background: There are few reports of endoscopic choledochoduodenal fistulotomy (endoscopic fistulotomy) in patients with papillary carcinoma by using a needle-knife.

Methods: Among 35 patients with papillary carcinoma requiring biliary drainage, 14 with a suprapapillary bulge underwent endoscopic fistulotomy alone or with widening of the fistula by using a standard sphincterotome or dilation balloon catheter.

Observations: Transfistula bile duct cannulation was successful on the first attempt in 13 of 14 patients (93%) and temporary biliary drainage through the fistula was successfully established in all 13 patients. The single complication was minor bleeding (7%) in 1 patient. In 6 patients with biliary obstruction who were not operative candidates, endoscopic fistulotomy was used for palliation, and all remained asymptomatic for a mean period of 3.2 months.

Conclusions: Endoscopic fistulotomy is an effective, relatively safe biliary drainage procedure. It should be considered in selected patients with bile duct obstruction caused by papillary carcinoma and a suprapapillary bulge caused by the dilated bile duct.

Background: Malignant obstructive jaundice (MOJ) is characterized by the presence of malignant tumors infiltrating or compressing the bile duct, causing poor bile drainage, generalized yellowing, pain, itching, and malaise. MOJ is burdensome for both the society and the families of affected patients and should be taken seriously.

Aim: To evaluate the clinical effect of stent placement during endoscopic retrograde cholangiopancreatography for relieving MOJ and the efficacy of percutaneous transhepatic biliary drainage in terms of liver function improvement, complication rates, and long-term patient outcomes.

Background: Intraoperative and postoperative biliary injuries remain significant complications of laparoscopic common bile duct exploration (LCBDE). Indocyanine green (ICG) has been shown to significantly reduce injuries caused by intraoperative operational errors. We found that the J-tube can reduce postoperative strictures and injuries to the common bile duct.

Background: Pancreatic trauma is a rare solid organ injury. Conservative treatment is often indicated in patients with no pancreatic duct injury, while patients with high-grade pancreatic damage most often require surgical intervention. Laparoscopic central pancreatectomy (LCP) is a parenchyma-sparing approach and can prevent endocrine and exocrine insufficiency after pancreatic resection.

We present a pioneering case of a duplication of the common bile duct associated with agenesis of the dorsal pancreas in a 66-year-old man. After an episode of cholestatic jaundice, radiological investigations revealed complex vascular and biliary anomalies, redefining the therapeutic strategy. Instead of risky surgery, endoscopic biliopancreatic drainage resolved the symptoms.

Lemmel syndrome involves a periampullary duodenal diverticulum (PAD), a pouch-like outpouching near the ampulla of Vater, compressing the common bile duct. We describe a case of severe abdominal pain in a patient who had a large periampullary diverticulum, managed with surgical intervention after an initial failed endoscopic retrograde cholangiopancreatography (ERCP). An elderly female patient in her early 90s arrived at the emergency department with severe cramping pain localized to the right upper quadrant of her abdomen, progressively intensifying over several weeks.
