Background: Laparoscopic surgery aims at reducing wound complications and improving cosmetics, among other advantages. High rates of postoperative ventral hernia (POVH) are observed after laparoscopic-assisted colectomies.

Materials And Methods: In a 2011 to 2016 retrospective study of all patients at Rabin Medical Center, we examined POVH prevalence after right hemicolectomy for neoplasia and correlation to specimen extraction site. We also compared laparoscopic-assisted colectomy to hand-assisted laparoscopic colectomy. Included were patients who had postoperative abdominal computed tomography or magnetic resonance imaging scan as part of their routine oncological follow-up to 6 months postsurgery. Patients were excluded for conversion to laparotomy, and prior abdominal surgeries after right colectomy and before follow-up computed tomography/magnetic resonance imaging scan. Demographic and surgical data were collected from patient electronic records, and scans reviewed for POVH by a designated radiologist.

Results: Of 370 patients, 138 (mean age 70.09 y, 58 males) were included: 54 (39.1%) were diagnosed with POVH, 42/72 (58.3%) at midline extraction site, and 12/66 (18.8%) at off-midline extraction sites (P<0.0001). Surgical site infections and patients positive for tumor metastasis were associated with higher POVH rates. Most (74%) POVHs were identified within 18 months postsurgery (P<0.0001). Body mass index, age, sex, diabetes mellitus, smoking, tumor size, lymph nodes positive for metastasis, and hand-assisted laparoscopic colectomy were not associated with POVH prevalence.

Conclusion: High rates of radiologically diagnosed POVH were found after laparoscopic-assisted colectomy, with association to midline extraction site, surgical site infections, and positive tumor distant metastasis.
