Laparoscopic ventral hernia repair: a systematic review

Abstract

<h4>Background</h4>Laparoscopic ventral hernia repair may be an alternative to open mesh repair as it avoids a large abdominal incision, and thus potentially reduces pain and hospital stay. This review aimed to assess the safety and efficacy of laparoscopic ventral hernia repair in comparison with open ventral hernia repair.<h4>Method</h4>A systematic review was conducted, with comprehensive searches identifying six randomised controlled trials (RCTs) and eight nonrandomised comparative studies.<h4>Results</h4>The laparoscopic approach may have a lower recurrence rate than the open approach and required a shorter hospital stay. Five RCTs (Barbaros et al., Hernia 11:51-56, 2007; Misra et al., Surg Endosc 20:1839-1845, 2006; Navarra et al., Surg Laparosc Endosc Percutan Tech 17:86-90, 2007; Moreno-Egea et al., Arch Surg 137:266-1268, 2002; Carbajo et al., Surg Endosc 13:250-252, 1999) reported no conversion (0%) to open surgery, and four nonrandomised studies reported conversions to open surgery ranging from 0% to 14%. Open approach complications generally were wound related, whereas the laparoscopic approach reported both wound- and procedure-related complications and these appeared to be less frequently reported.<h4>Conclusion</h4>Based on current evidence, the relative safety and efficacy of the laparoscopic approach in comparison with the open approach remains uncertain. The laparoscopic approach may be more suitable for straightforward hernias, with open repair reserved for the more complex hernias. Laparoscopic ventral hernia repair appears to be an acceptable alternative that can be offered by surgeons proficient in advanced laparoscopic techniques.
