ObjectiveTo examine the short-term outcomes after laparoscopic intraperitoneal onlay mesh (IPOM) compared with robot-assisted retromuscular repair of small to medium-sized ventral hernia.BackgroundWith the introduction of a robot-assisted approach, retromuscular mesh placement is technically more feasible compared with laparoscopic IPOM, with potential gains for the patient, including avoidance of painful mesh fixation and intraperitoneal mesh placement.MethodsThis was a nationwide cohort study of patients undergoing either laparoscopic IPOM or robot-assisted retromuscular repair of a ventral hernia with a horizontal fascial defect <7 cm in the period 2017 to 2022, matched in a 1:2 ratio using propensity scores. Outcomes included postoperative hospital length of stay, 90-day readmission, and 90-day operative reintervention, and multivariable logistic regression analysis was performed to adjust for the relevant confounder.ResultsA total of 1136 patients were included for analysis. The rate of IPOM-repaired patients hospitalized > 2 days was more than 3 times higher than after robotic retromuscular repair (17.3% vs. 4.5%, P < 0.001). The incidence of readmission within 90 days postoperatively was significantly higher after laparoscopic IPOM repair (11.6% vs. 6.7%, P =0.011). There was no difference in the incidence of patients undergoing operative intervention within the first 90 days postoperatively (laparoscopic IPOM 1.9% vs. robot-assisted retromuscular 1.3%, P =0.624).ConclusionsFor patients undergoing first-time repair of a ventral hernia, robot-assisted retromuscular repair was associated with a significantly reduced incidence of prolonged length of postoperative hospital stay and risk of 90-day readmission compared to laparoscopic IPOM.Copyright © 2023 Wolters Kluwer Health, Inc.
