P053 COMPARISON OF CLINICAL OUTCOMES BETWEEN INTRAPERITONEAL ONLAY MESH REPAIR (IPOM PLUS) AND ENHANCED-VIEW TOTALLY EXTRAPERITONEAL REPAIR (ETEP) FOR VENTRAL HERNIAS

Aim We have been performing intraperitoneal on lay mesh repair (IPOM plus) as the standard laparoscopic procedure for ventral hernia in our department. We introduced enhanced-view totally extraperitoneal repair (eTEP) for ventral hernia repair in 2018, and have performed 31 cases so far. We compared the outcomes of IPOM Plus and eTEP at our institution. Material and Methods Ventral hernia cases who underwent surgery at our department between 2018 and 2020 were included in the study. The postoperative outcomes and complications of the IPOM Plus and eTEP groups were evaluated retrospectively. Results There were 12 cases of IPOM plus, and all were incisional hernias. There were 31 cases of eTEP, including 7 cases of primary hernias and 24 cases of incisional hernias. Transversus abdominis muscle release (TAR) was added in 24 cases. The mean hernia size was 6.6 x 7.9 cm with IPOM Plus and 8.0 x 10.1 cm with eTEP, and the average meshes size was 15.5 x 22.0 cm and 20.3 x 23.6 cm, respectively. The mean postoperative hospital stay was 7.8 days and 5 days. Postoperative complications included 1 case of mesh bulging and 1 case of recurrence in the IPOM Plus group, 1 case of seroma and 1 case of intestinal obstruction in the eTEP. Conclusions The surgical outcomes for ventral hernias up to 8 cm wide were similar for IPOM Plus and eTEP. The eTEP can insert a larger mesh and may be useful for wider hernias (>8cm).
