  • Title: Extraction site location and incisional hernias after laparoscopic colorectal surgery: should we be avoiding the midline?

    Abstract:
    BACKGROUND: Laparoscopic colorectal procedures require specimen extraction. It is unclear whether extraction site affects the incidence of incisional hernia (IH). METHODS: Patients undergoing laparoscopic colectomy over a 6-year period were identified. Outcomes were compared between patients to evaluate the incidence of hernia. RESULTS: Among 480 laparoscopic colorectal procedures, extraction sites were midline (n = 305), muscle splitting (n = 128), Pfannenstiel (n = 26), and ostomy (n = 21). Average follow-up was 3.5 years. Age, gender, diagnosis, extraction incision length, and hospital stay were similar. The mean body mass index for all patients was 28 kg/m(2) and for those with IHs was 31 kg/m(2) (P = .008). The overall IH rate was 7%. Midline IHs accounted for 84% of all hernias, occurring in 8.9% of midline extractions (P < .05 vs nonmidline extractions). Hernia rates for muscle-splitting, Pfannenstiel, and ostomy site extractions were 2.3%, 3.8%, and 4.8%, respectively. CONCLUSIONS: Although midline hernia rates were lower than traditionally reported with open surgery, midline extraction sites have a higher chance of IH than nonmidline sites.
