Surgical treatment of large and complicated hiatal hernias with the new resorbable mesh with hydrogel barrier (Phasix™ ST): a preliminary study.

Abstract

Evaluation of the efficacy and safety of the new monofilament fully resorbable mesh with hydrogel barrier (Phasix™ ST), for large and complex hiatal hernia repair. Between December 2017 and December 2020, 60 patients with large or complicated hiatal hernia were treated (40 robotic and 20 laparoscopic procedures). The mesh was placed after primary closure of the hiatal defect, in an onlay fashion around the esophagus, followed by 360o fundoplication. Follow-up at 3, 6, 12, 18, 24months from intervention included clinical evaluation and upper GI endoscopy. In cases of recurrence, radiologic survey and manometry were utilized. There were no conversions to open repair or significant postoperative incidents. Over a median follow-up of 21months (range 3-36), no recurrences or mesh related complications were observed. From our early experience, Phasix™ ST mesh seems to be safe and effective for the reinforcement of crural defects in large and complex hiatal hernia.
