Abstract: Background: Unfortunate complications in some patients who undergo minimally-invasive resections for colorectal cancer using a minilaparotomy are the development of postoperative wound infection or tumor recurrence at in the minilaparotomy site. These complications are potentially avoidable. In an effort to prevent these problems, we designed an easy-to-use device named the Lap-Protector TM. The purpose of this study was to evaluate the efficacy of the Lap-Protector TM in preventing bacterial infection and tumor recurrence at minilaparotomy incision sites. Patients and Methods: Ninety-eight colon cancer patients who underwent minimally-invasive resections using minilaparotomy (minilaparotomy or laparoscopic-assisted approach) with the assistance of the Lap-Protector TM between January 1999 and August 2000 were compared with 87 patients treated without this device between January 1997 and December 1998. Postoperative wound infection and tumor recurrence rates at the minilaparotomy site were retrospectively analyzed. Results: Patient characteristics (age, sex, body mass index, and frequency of diabetes mellitus), tumor location, operative procedures, and pathological parameters were similar between the two groups. Four patients (4.6%) in the control group developed postoperative wound infections versus none in the Lap-Protector TM group (P=0.047). With a median follow-up of 8.3 (range, 1.3 to 19.3) and 29.7 (range, 8.4 to 54.4) months in the Lap-Protector TM group and control group, respectively, neither group has recorded a tumor recurrence at the minilaparotomy site. Conclusion: The Lap-Protector TM appears to prevent wound infection after minimally-invasive resections for colon cancer using a minilaparotomy. Longer follow-up to evaluate tumor recurrence rates at the minilaparotomy site is necessary.
