Abstract
Purpose
Robotic retromuscular abdominal wall repair (RAWR) for ventral hernias can be performed transabdominal or extraperitoneal by using an enhanced view totally extraperitoneal repair (eTEP). For defects in the meso- or epigastric region, an inverted approach can be used, starting the development of the totally extraperitoneal plane in the suprapubic region and progressing in a caudal-to-cranial direction (inverted TEP, iTEP). The aim of the study is to present the surgical technique and to report the short-term outcomes.
Methods
A retrospective analysis of a prospectively maintained database was performed, including patients who underwent a robotic RAWR using the iTEP approach between December 2019 and January 2022. The surgical technique was described, and patients’ characteristics and intra- and postoperative parameters were studied and compared to the TARUP technique (robotic transabdominal retromuscular umbilical prosthetic hernia repair).
Results
Thirty-four patients were treated with an iTEP approach, and 14 patients underwent a TARUP procedure. The median length of stay was 1 day (range 1–3), and there were no intraoperative complications in both groups. One patient (3%) required reoperation after an iTEP approach for a small bowel internal herniation due to a rupture of the posterior rectus sheath. There were no recurrences or mortality with a median follow-up of 15 months (range 3–29) in the iTEP group, compared to 35 months (range 29–37) in the TARUP group.
Conclusion
For defects in the upper abdominal region, a robotic RAWR with an iTEP approach appears to be safe and feasible. Long-term follow-up is needed to evaluate the late recurrence rate.
