P-BN11 Patient Reported Outcomes of Phasix™ ST Mesh for Laparoscopic Hiatal Hernia Repair

Abstract

Background Laparoscopic hiatal hernia repair continues to suffer from high recurrence rates, which has prompted the use of mesh reinforcement by some surgeons. Use of mesh however remains controversial due to its association with complications such as erosion, fibrosis and oesophageal stenosis. Biosynthetic Poly-4-Hydroxybutyrate Phasix™ ST mesh is an emerging technology which combines the durability of synthetic mesh with the remodelling characteristics of biologic mesh and includes an anti-adhesion hydrogel barrier. There is a paucity of patient reported outcome data for Phasix™ ST mesh. This study evaluates early patient reported outcomes following laparoscopic hiatal hernia repair with Phasix™ ST mesh. Methods Adult patients undergoing laparoscopic hiatal hernia repair with Phasix™ ST mesh between July 2020 to June 2021 at our institution were identified. Prospective data, including demographic data and complication rates, was collected from electronic and paper medical records. The 12-Item Short Form Survey (SF-12) was administered to assess quality of life pre-operatively and post-operatively with a minimum 30-day follow-up. Results Fourteen patients (12 female, one male) were included with a median age of 66 years (range 52-79). There were no intraoperative complications, mesh-related complications, re-operation, re-admission, or recurrence at a median follow-up of 4 months (IQR 4.0). Median physical health component (PHC) score was 32.7 (IQR 6.2) at baseline and increased to 41.6 (IQR 13.7) post-operatively. Median difference in PHC score was +11.4 (IQR 10.7). Median mental health component (MHC) score was 39.8 (IQR 12.5) at baseline and increased to 57.4 (IQR 8.2) post-operatively. Mean difference in MHC score was +17.7 (IQR 15.9). Conclusions To our knowledge, this is the first report of outcomes on the use of Phasix™ ST mesh for laparoscopic hiatal hernia repair in the United Kingdom. Our study found that it is associated with improvements in both physical and mental quality of life in the short-term post-operative follow-up, although there is some variation in the degree of improvement reported.
