A retrospective cohort study of laparoscopic enhanced view totally extra-peritoneal Rives-Stoppa (eTEP-RS) repair of incisional ventral hernias in patients with morbid obesity.

backgroundIncisional hernia (IH) repair in morbidly obese (MO) patients poses significant challenges due to higher risks of complications and recurrence. Traditional open repairs are linked to increased morbidity, driving interest in minimally invasive techniques. The enhanced view totally extra-peritoneal Rives-Stoppa (eTEP-RS) technique shows promise as a laparoscopic method for IH repair, but data on its efficacy and safety in MO patients are limited. This study aims to evaluate the efficacy, safety, and feasibility of the eTEP-RS approach specifically for IH repair in this high-risk population.

methodsAnalysis of a retrospective cohort of consecutive patients undergoing laparoscopic eTEP-RS for IH repair between 2017 and 2022 which included 135 patients, categorized into two groups based on body mass index (BMI): the MO group (BMI > 35 kg/m

resultsPatients in the MO group had significantly more type 2 diabetes mellitus (n = 18, 51% vs n = 25, 25%; p = 0.004), hypertension (n = 35, 73% vs n = 75, 53%; p = 0.017), dyslipidemia (n = 29, 60% vs n = 58, 41%; p = 0.021), ASA score 3 (n = 18, 52% vs n = 23, 23%; p = 0.004), a history of previous umbilical hernia repair (n = 13, 27% vs n = 13, 9.2%; p = 0.002), and bariatric surgery (n = 10, 29% vs n = 13, 13%; p = 0.035). There were no differences in intra-operative characteristics, operative times, or intra-operative complications between groups. During a median follow-up period of 1 year (IQR 40-680 days), there were no differences in hernia recurrence (n = 2, 5.7% vs n = 9, 9%; p = 0.07), time to recurrence, or chronic analgesia usage between groups.

conclusionThe laparoscopic eTEP-RS approach was safe and effective for IH repair in patients with MO, demonstrating comparable post-operative outcomes and recurrence rates to those with a lower BMI in a selected cohort of patients.
