Minilaparotomy wound edge protector (Lap-Protector): a new device.

Laparoscopic-assisted or minimally invasive surgery involving minilaparotomy is occasionally complicated by infection of the minilaparotomy wound caused by intestinal bacteria. Furthermore, when this procedure is performed to excise colorectal or gastric cancer, tumor recurrence may develop in the minilaparotomy wound. In an attempt to minimize the risk of these complications, we developed a new, easy-to-use device which we named the "Lap-Protector." Minilaparotomy was performed using the Lap-Protector in 28 patients with colon cancer and eight patients with early gastric cancer who underwent minimally invasive surgery between January and September, 1999. During a median follow-up period of 15.9 (range 12.4-21.0) months, none of the 36 patients showed any sign of wound infection or tumor recurrence in the minilaparotomy wound. These results indicated that the Lap-Protector is a safe and useful device that may help to prevent infections and cancer cell contamination of the minilaparotomy wound.
