Abstract: | Laparoscopic repair of ventral abdominal wall hernias involves intraperitoneal placement of a mesh, which may lead to adhesion formation and bowel fistulation. The first series of selected patients with ventral abdominal wall hernias treated laparoscopically by extraperitoneal placement of a polypropylene mesh is presented. Thirty-four patients (24 women and 10 men; median age, 52 years range, 34-70]) were selected from among 122 patients undergoing laparoscopic ventral hernia repair. Of these patients, 18 had a primary ventral abdominal wall hernia and 16 had an incisional hernia. After reduction of sac contents and adhesiolysis intraperitoneally, a large flap of peritoneum (with extraperitoneal fat, fascia, and posterior rectus sheath where present) was raised to accommodate a suitably sized polypropylene mesh, which was then covered again with the peritoneal flap at the end of the procedure. Intraoperatively, apart from circumcision of the hernial sac at the neck, a total of 24 iatrogenic peritoneal tears occurred in 20 patients, mainly at the site of the previous scar. In two patients, it was observed that greater than 25% of the mesh was exposed after the procedure. The median (+/-SD) duration of hospitalization postoperatively was 1 day (+/-0.56). One patient's hernia recurred 4 months after surgery, and one patient's infected mesh was removed 8 months after surgery. Laparoscopic extraperitoneal placement of a mesh is feasible and appears to be an advance over laparoscopic intraperitoneal mesh placement for ventral abdominal wall hernias in selected patients. However, longer follow-up and controlled clinical trials will be necessary before any firm conclusions can be drawn. |
