Abstract
BACKGROUND: The optimal repair of ventral hernia remains unknown. We aimed to evaluate the results after robotic-assisted laparoscopic transabdominal repair with retrorectus mesh placement (rRetrorectus) compared with laparoscopic intraperitoneal onlay mesh repair (IPOM) for patients with small- or medium-sized ventral hernia. METHODS: This was a retrospective cohort study of consecutive patients undergoing elective rRetrorectus or IPOM repair for small or medium-sized primary ventral or incisional hernias. The primary outcome was the postoperative need for transverse abdominis plane (TAP) block or epidural analgesia, secondary outcomes were length of stay and postoperative complications. All patients were followed for 30 days postoperatively. RESULTS: A total of 59 patients were included undergoing rRetrorectus (n = 27) and IPOM (n = 32). Patients in the two groups were comparable in terms of age, sex, comorbidities, smoking status, body mass index (BMI), and type of hernia. The median fascial defect area was slightly larger in the rRetrorectus group (9 cm2 vs. 6.2 cm2, P = 0.031). The duration of surgery was longer for rRetrorectus (median 117.2 min. vs. 84.4, P = 0.003), whereas the postoperative need for TAP block or epidural analgesia was less after rRetrorectus compared with IPOM (3.7% versus 43.7%, P = 0.002). There were no severe complications or reoperations after either procedure. The length of stay was shorter after rRetrorectus (median 0 vs. 1 day, P < 0.001). CONCLUSIONS: rRetrorectus was associated with reduced postoperative analgesic requirement and shorter length of stay compared with laparoscopic IPOM. Registration Clinicaltrial.gov: NCT05320055.
