Laparoscopic repair of incisional and other complex abdominal wall hernias.

Incisional hernia is one of the most common complications of abdominal surgery, with a reported occurrence rate of up to 20% after laparotomy. The high incidence of hernia formation significantly contributes to both patient morbidity and health care costs. Although a variety of approaches have been described to repair these defects, historically the results have been disappointing. Recurrence rates after primary repair have been reported to range from 24% to 54%. The recent advent of laparoscopic ventral hernia repair (LVHR) has offered promising outcomes by combining tension-free repair using a prosthesis with minimally invasive techniques, lowering reported recurrence rates to <10%. This review discusses standardized, well-researched techniques that have contributed to the success of LVHR. We also discuss how these techniques have been modified for laparoscopic repair of suprapubic lumbar hernias, hernias near the iliac crest, and parastomal hernias. In addition, we review our own experience with LVHR in the context of the principles discussed.
