Abstract
Component separation with mesh reinforcement has become the primary modality for complex abdominal wall reconstruction. However, many fundamental questions remain unanswered, such as whether underlay versus overlay mesh placement is superior, and what is the best means of suture fixation technique for mesh placement? This study presents the senior author's technique for onlay biologic mesh placement with multipoint suture fixation in combination with component separation and its subsequent low recurrence rates. This is a retrospective review of the senior author's cases of component separation with onlay biologic mesh placement during his tenure at the home institution of the University of Alabama at Birmingham. A total of 75 patients were included, all of whom underwent complex abdominal wall reconstruction from September 2002 to April 2012. Patients were excluded from the dataset if their surgery occurred less than two years before date of data collection to give a minimum 2-year follow-up. Patients were identified by Current Procedural Terminology codes for component separation and their charts reviewed by the home institution's electronic medical record. Data point entries included patient demographics and comorbidities, concomitant procedures such as bowel resection or panniculectomy, and characteristics of the reconstruction such as type of mesh used. Primary data endpoints were complications following surgery, particularly recurrence and laxity. A total of 75 patients were included in the study from September 2002 to April 2012 with a minimum 2-year follow-up period. The recurrence rate was 13 per cent and the rate of laxity 2.7 per cent. There was one death (1.35%). The most frequent complication was seromas at a rate of 17 per cent. Multipoint fixation suture technique for abdominal wall reconstruction with component separation and onlay biologic mesh is a reproducible technique with reliably low recurrence rates.
