Background: Incisional ventral hernias(IVH) are a common complication following open abdominal surgery. The aim of this study was to uncover the hidden costs of IVH following right-sided hepatectomy.
Methods: Outcomes and hospital billing data for patients undergoing open(ORH) and laparoscopic right-sided hepatectomies(LRH) were reviewed from 2008 to 2018.
Results: Of 327 patients undergoing right-sided hepatectomies, 231 patients were included into two groups: ORH(n = 118) and LRH(n = 113). Median follow-up-times and time-to-hernia were 24.9-months(0.3-128.4 months) and 40.5-months(0.4-81.4 months), respectively. The incidence of hernias at 1, 3, 5, and 10 years was 6/231(2.6%), 13/231(5.6%), 15(6.5%), and 17/231(7.4%); ORH = 14, LRH = 3, p = 0.003), respectively. In terms of IVH repair(IVHR), total operative costs ($10,719.27vs.$4,441.30,p < 0.001) and overall care costs ($20,541.09vs.$7,149.21,p = 0.044) were significantly greater for patients undergoing ORH. Patients whom underwent ORHs had longer hospital stays and more complications following IVHR. Risk analysis identified ORH(RR-10.860), male gender(RR-3.558), BMI ≥30 kg/m2(RR-5.157), and previous abdominal surgery(RR-6.870) as predictors for hernia development (p < 0.030).
Conclusion: Evaluation of pre-operative hernia risk factors and utilization of a laparoscopic approach to right-sided hepatectomy reduces incisional ventral hernia incidence and cost when repair is needed.
