Endoscopic self-expandable metal stent versus endoscopy vacuum therapy for traumatic esophageal perforations: a retrospective cohort study.

Background: Traumatic esophageal perforations (TEP) are a grave medical condition and require immediate intervention. Techniques such as Esophageal Self-Expandable Metal Stent (E-SEMS) and Endoscopic Vacuum Therapy (EVT) show promise in reducing tissue damage and controlling esophageal leakage. The present study aims to compare the application of EVT to E-SEMS placement in TEP.

Lower esophageal sphincter pressure measurement under standardized inspiratory maneuveurs.

Background: Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter.

Aim: To describe a method of measuring LES pressure during standardized inspiratory maneuvers with increasing loads.

Endoscopic management of biliary complications after liver transplantation.

Background: Liver transplantation is the only effective treatment for chronic liver diseases and terminal survival rate has increased in recent decades. However, biliary complications have high incidence and remain as the "Achilles heel" for liver transplantation.

Aim: To evaluate retrospectively endoscopic treatment outcomes of biliary complications in post-liver transplantations.
