Transgastric ventral hernia repair: a controlled study in a live porcine model (with videos).

Abstract：

BACKGROUND:Ventral hernia repair is currently performed via open surgery or laparoscopic approach. OBJECTIVE:To develop an alternative ventral hernia repair technique. SETTING:Acute and survival experiments on twelve 50-kg pigs. DESIGN AND INTERVENTIONS:An endoscope was introduced transgastrically into the peritoneal cavity. An abdominal wall hernia was created through a 5-mm skin incision followed by a 5-cm-long incision of the abdominal wall muscles and aponeurosis. A hernia repair technique was developed in 3 acute experiments. Then animals were randomized into 2 groups. In the experimental group (5 animals) Gore-Tex mesh was transgastrically attached to the abdominal wall, repairing the previously created abdominal wall hernia. In the control group (4 animals), the hernia was not repaired. In both groups, the endoscope was then withdrawn into the stomach, and the gastric wall incision was closed with T-bars. The animals survived for 2 weeks and were then euthanized. MAIN OUTCOME MEASUREMENT:The presence of ventral hernia on necropsy. RESULTS:In the control group, the ventral hernia was present on necropsy in all animals. In the experimental group, the ventral hernia was easily repaired, with no evidence of hernia on necropsy. In the first animal in the experimental group, necropsy revealed infected mesh. After this discovery, we used sterilized cover for mesh delivery and did not find any signs of infection in 4 subsequent study animals. LIMITATION:The study was performed in a porcine model. CONCLUSIONS:Transgastric ventral hernia repair is feasible, technically easy, and effective. It can become a less invasive alternative to the currently used laparoscopic and surgical ventral hernia repair.
