*Purpose: To analyze the outcome of IVH repairs in liver transplant recipients using a minimally invasive technique.

*Methods: From 2016 to 2018, we analyzed the IVHR performed, with primary focus on the OLT group. For comparison purposes, 4 groups were studied during this period: group I: Open IVHR in Non-OLT (n=8), group II: RAI in Non-OLT (n=7), group III: Open-OLT (n=8), and group IV: RAI-OLT (n=12). Demographics, causes of IVH, BMI, analgesics need, and complications were studied, as well as fascial defects (in cm²), OR time and hospital stay. One type of composite mesh (Covidien, Symbotex™) was used in all 4 groups of patients. Three 8-mm robotic ports (one infra umbilical and one in each lower quadrant) and, one type of running suture (Covidien V-Loc™) were used in RAIs. Clinical assesment and laboratory tests were done periodically. Statistics: t-test and Chi² were used.

*Results: No statistical differences were observed regarding demographics, BMI or analgesics need. OLT on mTOR agents (n=4) had IVHR (20%). Outcomes of OLT were no different from Non-OLT patients. However, statistical differences were found between OLT groups. Group IV, when compared with group III, needed less mesh area for repairs and they also had a shorter hospital stay (Table). In addition, the conversion rate from RAI to open was 30% vs 7.7% between groups II and IV (P<0.000, not shown).

*Conclusions: The implementation of a minimally invasive technique to treat OLT-IVH at our program has reduced the OR time and the hospital stay significantly in the period studied. The experience gained with RAI has allowed performance of more challenging cases with reduced morbidity and discomfort.
