Percutaneous Treatment of Biliary Strictures After Pediatric Liver Transplantation.

BACKGROUND Biliary strictures (BS) are frequent after pediatric liver transplantation (LTx) and in spite of ongoing progress, they remain a significant cause of morbidity. In children, the majority of reconstruction is hepatico-jejunal anastomosis (HJA). The aim of this study was to analyze our experience in percutaneous transhepatic treatment of BS.

Endoscopic treatment in biliary strictures after pediatric liver transplantation.

Background And Aim: The aim of the study was to assess efficacy and safety of endoscopic treatment in BS after pediatric LTx.

Methods: We retrospectively reviewed data of patients with DDA who developed BS and underwent ERCP.

Results: Of 189 transplanted patients with DDA, strictures developed in 30 (16%).

Outcomes and complications of self-expanding metal stent placement for malignant colonic obstruction in a single-center study.

Introduction: Approximately 20% of cases of colorectal cancer are accompanied by acute colonic obstruction. While emergency colonic surgery is associated with high mortality and morbidity rates, placement of a self-expanding metal stent (SEMS) has been suggested as an alternative method. The SEMS placement can serve as either a definitive treatment in palliative cases or a bridge to surgery.

MRCP Versus ERCP in the Evaluation of Chronic Pancreatitis in Children: Which Is the Better Choice?

Objectives: To evaluate the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) in the detection of chronic pancreatitis (CP)-specific changes in the pediatric population.

Methods: The study included 48 children with pancreatic disorders subjected to both endoscopic retrograde cholangiopancreatography (ERCP) and MRCP within a 1- to 4-month interval. The sensitivity, specificity, positive predictive value, and negative predictive value of MRCP in the detection of CP-specific changes were determined using ERCP as a diagnostic standard.

Frey operation for chronic pancreatitis associated with pancreas divisum: case report and review of the literature.

Pancreas divisum (PD) is the most common congenital anomaly of the pancreas, which increases susceptibility to recurrent pancreatitis. Usually, after failure of initial endoscopic therapies, surgical treatment combining pancreatic resection or drainage is used. The Frey procedure is used for chronic pancreatitis, but it has not been reported to be applied in an adult patient with PD-associated pancreatitis.

Efficiency of pancreatic duct stenting therapy in children with chronic pancreatitis.

Background: Chronic pancreatitis (CP) is a rare disease in childhood. Although ERCP is commonly performed in children, the effect of pancreatic duct stenting therapy in children with CP is unknown.

Objective: To investigate the efficacy of pancreatic duct stenting in children with CP.

Treatment of large colorectal neoplasms by endoscopic submucosal dissection: a European single-center study.

Objective: Endoscopic submucosal dissection (ESD) has a high curative resection rate for gastrointestinal mucosal lesions, but is not used widely in Europe because of a high complication rate and a long learning curve. This study analyzed the ESD learning curve at a single European treatment center.

Materials And Methods: ESD and hybrid-ESD (hESD) procedures were used to treat large colonic lesions that could not be resected in one piece by other endoscopic methods.

Narrow‑band imaging and white‑light endoscopy for detection of colorectal polyps: a randomized study.

Introduction: Narrow‑band imaging (NBI) is a new, promising technique that might be helpful in the detection of colorectal polyps during colonoscopy.

Objectives: The aim of the study was to compare the usefulness of NBI with white‑light endoscopy (WLE) for the detection of polyps as well as to determine the distribution of missed polyps.

Patients And Methods: This was a randomized controlled trial.

Endoscopic submucosal dissection for the treatment of neoplastic lesions in the gastrointestinal tract.

Aim: To investigate the indications, resection rate, and safety of endoscopic submucosal dissection (ESD) for neoplastic lesions in the gastrointestinal tract at a European referral center.

Methods: We carried out a retrospective analysis of the ESD procedures performed in our center for mucosal neoplastic and submucosal lesions of the gastrointestinal tract. The duration of the procedure, en bloc and complete (R0) resection rates, and complication rates were evaluated.

Endoscopic submucosal dissection for treatment of gastric subepithelial tumors (with video).

Background: Endoscopic submucosal dissection (ESD) is a well-accepted method for removing superficial mucosal tumors; however, there is limited data on the use of this method for removing subepithelial tumors.

Objective: To investigate the efficacy, safety, and outcome of ESD for gastric subepithelial tumors and determine factors related to treatment success.

Design: Retrospective analysis of a prospectively maintained database.
