Between 1976 and 1988, we treated 13 perforations of the thoracic esophagus, excluding ruptured carcinoma and intraoperative wounds, by mechanical sutures without exclusion. The delay between perforation and treatment ranged from eight to 168 hours, more than 24 hours in 11. The length of perforation was 0.5 to 15.0 centimeters. Suture was covered with a flap in ten instances; an antireflux procedure was associated with five instances. No digestive ostomies were performed. There was one death; a patient who was comatose upon arrival. The results of this small series suggest that myotomy exposing the mucosa and a flap are two essential elements of the technique; perforations of less than 6 centimeters, even when seen late, may be treated by primary surgical closure.

Tissue adhesives have attracted wide attention as alternatives to sutures. Further developments in adhesives with excellent adhesion and biocompatibility for wet tissue surfaces are still required. This study provides a new solution for the development of bioadhesives for use on tissue surfaces under wet conditions.

Introduction: Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) has emerged as a crucial component of critical care medicine, mainly as a lifesaving intervention for patients experiencing refractory cardiac arrest and respiratory failure.
Background: In the past, VA-ECMO decannulation was surgical and often associated with a high rate of periprocedural complications, such as surgical site infection, bleeding, and patient mobilization costs. To reduce the rate of these adverse events, many percutaneous techniques utilizing suture-mediated closing devices have been adopted.

Cardiovascular diseases (CVDs) were responsible for approximately 19 million deaths in 2020, marking an increase of 18.7% since 2010. Biological decellularized patches are common therapeutic solutions for CVD such as cardiac and valve defects.

Objective: Inferior pole patellar fractures (IPPFs) pose a significant challenge due to their complex fracture patterns and high risk of complications associated with current treatment methods. This study aims to (1) characterize the fracture patterns of IPPFs using fracture mapping and (2) compare the biomechanical stability and clinical outcomes of treatment with anchor suture with patellar cerclage versus Kirschner-wire tension band combined with patellar cerclage.
Methods: (1) A retrospective analysis was conducted on 61 patients with IPPF.

Objectives: This study aims to analyze the biomechanics of three kinds of rigid internal fixation methods for condylar head fractures.
Methods: A three dimensional finite element model of the normal mandible was constructed. It was then used to prepare condylar head fracture finite element model and three kinds of rigid internal fixation finite element model (unilateral tension screw, bilateral tension screw, tension screw+titanium plate).
