Long-term results with biosynthetic absorbable P4HB mesh in ventral abdominal wall repair: a multicentre analysis.

Background: The aim of this multicentre study was to analyse the outcomes of biosynthetic absorbable poly-4-hydroxybutyrate (P4HB) prosthesis implantation in patients undergoing ventral hernia repair (VHR) in the context of different degrees of contamination.

Methods: From May 2016 to December 2021, a multicentre retrospective analysis of patients who underwent elective or urgent hernia repair with P4HB prosthesis was performed in seven hospitals in Spain and Portugal. Patients with a postoperative follow-up of less than 20 months and those within the theoretical period of prosthesis resorption were excluded from the study.

Influence of Mesenchymal Stem Cell Sources on Their Regenerative Capacities on Different Surfaces.

Current gold-standard strategies for bone regeneration do not achieve the optimal recovery of bone biomechanical properties. To bypass these limitations, tissue engineering techniques based on hybrid materials made up of osteoprogenitor cells-such as mesenchymal stem cells (MSCs)-and bioactive ceramic scaffolds-such as calcium phosphate-based (CaPs) bioceramics-seem promising. The biological properties of MSCs are influenced by the tissue source.

Long-term results of botulinum toxin type A in complex abdominal wall repair and review of the literature.

Administration of botulinum toxin (BTX) is being used in cases of complex ventral hernia for the reconstruction of the linea alba and closure of the abdominal wall. However, there are no published results regarding the long-term effects of BTX and its implication in hernia recurrence. Our purpose is to evaluate the outcomes in hernia recurrence of the administration of BTX in complex ventral hernia repair.

Surgical treatment of large incisional hernias with intraperitoneal composite mesh: a cohort study.

Purpose: Patients with large incisional hernias have significant morbidity and their management is a challenge for the surgical team because of the large abdominal wall involvement. The choice of surgical technique is still controversial. The purpose of this study is to analyze the predictive factors for recurrence after intraperitoneal mesh repair in patients with large incisional hernias.

Single-blinded randomized trial of mechanical bowel preparation for colon surgery with primary intraperitoneal anastomosis.

Introduction: We report the final analysis of a prospective single-blinded randomized trial designed to investigate whether omission of preoperative mechanical bowel preparation increases the rate of surgical-site infection and anastomotic failure after elective colon surgery with intraperitoneal anastomosis by a single surgeon.

Patients And Methods: Patients scheduled to undergo an elective colon or proximal rectal resection with a primary anastomosis by a single surgeon were randomized to receive either oral polyethylene glycol (Group A) or no mechanical bowel preparation (Group B). Patients were followed by an independent surgeon.
