Laparoscopic versus open ventral hernia repair in patients with chronic liver disease.

Background: Previous studies demonstrated laparoscopic ventral hernia repair (LVHR) to be associated with fewer short-term complications than open ventral hernia repair (OVHR). Little literature is available comparing LVHR and OVHR in chronic liver disease (CLD) patients.

Methods: Patients with model for end-stage liver disease score ≥9 who underwent elective ventral hernia repair in the National Surgical Quality Improvement Program Database were included. 30-day outcomes were compared between LVHR and OVHR after adjusting for hernia disease severity, baseline comorbidities and demographic factors.

Results: A total of 3594 ventral hernia repairs were included, 536 (14.9 %) of which were LVHR. After adjusting for other confounders, LVHR was associated with a lower incidence of wound-related complications (0.23, 95 % CI 0.07-0.74, p = 0.01), shorter length of stay (mean 3.7 vs. 5.0 days, p < 0.01) than OVHR, but similar systemic complications (p = 0.77), bleeding complications (p = 0.69), unplanned reoperation (p = 0.74) or readmission (p = 0.40). Propensity score-matched comparison showed similar conclusions. Five hundred and sixty-two patients had ascites, among whom 35 (6.2 %) underwent LVHR. In this subcohort, LVHR was associated with higher mortality (OR 5.36, 95 % CI 1.00-28.60, p = 0.05), systemic complications (OR 7.03, 95 % CI 2.06-24.00, p < 0.01), and unplanned reoperation (OR 6.03, 95 % CI 1.51-24.12, p = 0.01) than OVHR.

Conclusions: In comparison with OVHR, LVHR is associated with similar short-term outcomes except for lower wound-related complications and shorter length of stay in CLD patients. However, when patients have ascites, LVHR is associated with higher mortality, systemic complications, and unplanned reoperation.
