Abstract

Introduction: the botulinum toxin A (BTA) has been used to achieve a chemical component separation, and it has been used with favorable outcomes for the repair of complex ventral hernia (CVH) with and without loss of domain (LD). The aim of this study is to describe our early experience with the chemical component separation in the United Sates. Methods: a retrospective observational study of all patients who underwent ventral hernia repair for CVH with or without LD between July 2018 and June 2020. Preoperative BTA was injected in all patients via sonographic guidance bilaterally, between the lateral muscles to achieve chemical denervation before the operation. Patient demographics, anatomical location of the hernia, perioperative data and postoperative data are described. Results: 36 patients underwent this technique before their hernia repair between July 2018 to June 2020. Median age was 62 years (range 30-87). Median preoperative defect size was 12cm (range 6-25) and median intraoperative defect size was 13cm (range 5-27). Median preoperative hernia sac volume (HSV) was 1338cc (128-14040), median preoperative abdominal cavity volume (ACV) was 8784cc (5197-18289) and median volume ration (HSV/ACV) was 14%. The median OR time for BTA administration was 45 minutes (range 28-495). Seroma was the most common postoperative complication in 8 of the patients (22%). Median follow up was 43 days (range 0-580). Conclusion: preoperative chemical component separation with BTA is a safe and effective adjunct to hernia repair in CVH repairs where a challenging midline fascial approximation is anticipated.
