Background: Pancreatic endoscopic stenting aims to relieve abdominal pain due to chronic pancreatitis. Optimal treatment modalities and post-treatment effects have still to be determined. The object of this study was to investigate the results of a standardized protocol of endoscopic stenting.
Methods: Twenty-three patients with abdominal pain due to chronic pancreatitis and stricture of the distal main pancreatic duct were treated according to the following protocol: after balloon dilation of the stenosis, a 10F stent was placed into the main pancreatic duct and then exchanged every 2 months, the total duration of drainage being 6 months.
Results: Use of analgesics could be discontinued in 17 patients (74%) on termination of drainage, and in 12 patients (52%) 1 year later. These results were significantly associated with reduction of main pancreatic duct diameter and resolution of stricture, but were not influenced by abstinence from alcohol and pancreatic enzyme supplementation.
Conclusions: Pancreatic duct stenting results in short-term clinical improvement in patients with chronic pancreatitis and proximal main pancreatic duct stricture. Persistence of advantageous clinical results is to be expected in 50% of cases and when strictures have resolved.

Cholangiocarcinoma is the second most common primary liver cancer, and its global incidence has increased in recent years. Radical surgical resection and systemic chemotherapy have traditionally been the standard treatment options. However, the complexity of cholangiocarcinoma subtypes often presents a challenge for early diagnosis.

Choledochal cysts (CCs) are rare cystic dilations of the intrahepatic and/or extrahepatic bile ducts. Malignancies arising during follow-up after excision of CCs have been reported in both children and adults, with no typical time frame for malignancy development. We present a case of a patient diagnosed with CCs 36 years ago, who underwent resection and subsequently developed cancer.

Background/aims: Endoscopic retrograde cholangiopancreatography (ERCP) is an essential diagnostic and therapeutic method for pancreato-biliary disorders in adults, but its use in pediatric populations remains limited. This study aims to evaluate the indications, technical success, and safety of ERCP in pediatric patients.
Materials And Methods: A retrospective analysis of all ERCP procedures performed on patients under 18 years of age was conducted at 2 tertiary centers in Türkiye (Harran University and Gaziantep University Hospital) during the period between January 2013 and May 2024.

Purpose: This study aimed to investigate whether tumor-associated lymphatic vessel density (LVD) could predict the survival of patients with hepato-biliary-pancreatic (HBP) cancers after radical resection.
Methods: A systematic search was conducted using PubMed, Embase, and Cochrane Library from the inception to July 31, 2024 for literature that reported the role of LVD in overall survival (OS) and recurrence-free survival (RFS) of patients with HBP cancers after radical resection.
Results: Ten studies with 761 patients were included for the meta-analysis.

Background: Adverse events after endoscopic retrograde cholangiopancreatography (ERCP) are rare, and post-ERCP pancreatitis is a serious adverse event. This study aimed to determine the role of aggressive intravenous hydration with lactated Ringer's solution at a specific volume with 20% human albumin before ERCP in reducing the incidence of post-ERCP pancreatitis.
Methods: This study was a single-centre randomized clinical trial.
