Urinary Bladder Matrix Scaffolds Promote Pericardium Repair in a Porcine Model.

Pericardium closure after cardiac surgery is recommended to prevent postoperative adhesions to the sternum. Synthetic materials have been used as substitutes, with limited results because of impaired remodeling and fibrotic tissue formation. Urinary bladder matrix (UBM) scaffolds promote constructive remodeling that more closely resemble the native tissue.

Biomechanical Features of Reinforced Esophageal Hiatus Repair in a Porcine Model.

Recurrence rates in the laparoscopic repair of the hiatal hernia range from 12% to 59%. Limitation of reinforcement has been principally the risk of adverse events caused by synthetic materials. Biologic and resorbable synthetic materials are valid alternatives.

Urinary bladder matrix scaffolds strengthen esophageal hiatus repair.

Background: Laparoscopic repair of the hiatal hernia is associated with a recurrence rate between 12% and 42% depending on the defect size. Although the impact of hiatal reinforcement on long-term recurrence remains controversial, the main limitation of this approach has been the risk of adverse events related with the use of synthetic materials in the vicinity of the esophagus.

Methods: A total of 14 female domestic pigs underwent laparoscopic primary hiatal hernia repair of a simulated defect in the esophageal hiatus.

[Radiofrequency ablation for Barrett's esophagus. Preliminary experience].

Unlabelled: Endoscopic radiofrequency ablation makes use of warm energy to ablate the esophagus's surface where the epithelial anomaly is located.

Patients And Methods: 50 adults patients with the diagnosis of EB according to Vienna Classification were included.

Objectives: To evaluate the security and efficacy of ARF in patients with EB.

Autoadjustable sutures and modified seldinger technique applied to laparoscopic jejunostomy.

This is a simple technique to be applied to those patients requiring an alternative feeding method. This technique has been successfully applied to 25 patients suffering from esophageal carcinoma. The procedure involves laparoscopic approach, suture of the selected intestinal loop to the abdominal wall and jejunostomy using Seldinger technique and autoadjustable sutures.

Electrical stimulation to increase lower esophageal sphincter pressure after POEM.

Introduction: Postoperative reflux remains to be a challenge for patients with achalasia undergoing Heller myotomy. Similarly, per-oral endoscopic myotomy (POEM) is gaining rapid acceptance but the impossibility of adding a fundoplication is questioned as the main pitfall to control reflux. Electrical stimulation of the lower esophageal sphincter (LES) has emerged as a new alternative for the treatment of reflux disease.
