Biliary stent migration occurs in about 5% of patients. The most common complications secondary to stent migration are pancreatitis, small bowel perforation and peritonitis. We report the case of a patient presenting with an abdominal wall abscess secondary to migration of a biliary stent. Direct abdominal radiography, abdominal ultrasound and CT scan have proved very useful in the diagnosis, providing the correct localisation of the stent in the left rectus muscle of the abdominal wall that led to a surgical approach under local anaesthesia for the removal, and abscess formation surrounding the stent. The patient was discharged on the day after surgery. After reviewing the literature concerning this rare complication, the Authors conclude that closer monitoring of patients with biliary prostheses is needed to prevent the migration and the consequent serious complications.

Clinical evaluation of endoscopic biliary stenting in treatment of malignant obstructive jaundice.
World J Gastrointest Surg
January 2025
Department of General Surgery, Shenzhen University General Hospital, Shenzhen 518000, Guangdong Province, China.
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.
Clinical application of indocyanine green fluorescence imaging in laparoscopic cholecystectomy with common bile duct exploration and J-Tube drainage.
World J Gastrointest Surg
January 2025
Department of Hepatobiliary Surgery, Affiliated Nantong Hospital Third of Nantong University, Nantong 226006, Jiangsu Province, China.
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: Most patients undergoing pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) develop recurrence. No previous studies have investigated predictors of local-only recurrence following PD for PDAC. Our study aimed to determine timing, pattern and predictors of any-site and local-only recurrence following PD for PDAC.

Digestive Disease Center and Research Institute, Department of Internal Medicine, SoonChunHyang University School of Medicine, Cheonan, Korea.
Background And Aim: Although long self-expandable metal stent (SEMS) with a sufficient intragastric portion is typically preferred for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), this design can complicate endoscopic re-intervention for recurrent biliary obstruction (RBO). We evaluated the efficacy and safety of endoscopic re-intervention for RBO through the stent after EUS-HGS using a novel partially covered SEMS with an anchoring flange.
Methods: The partially covered SEMS was designed with a intrahepatic uncovered portion measuring 1.
Background And Aim: Managing benign biliary stricture endoscopically is complicated and challenging. This study aimed to evaluate the safety and efficacy of a 6-month placement of a fully covered self-expanding metallic stent for refractory benign biliary stricture.
Methods: Twenty-two patients with refractory benign biliary stricture (13 with chronic pancreatitis and 9 without) were recruited from five higher tertiary care centers.
