Background:
Controversy exists regarding the safety and effectiveness of minimally invasive inguinal hernia repairs in patients with a history of prior urologic pelvic operations (PUPO), such as a prostatectomy, which causes scarring and disruption of the retropubic tissue planes. Our study sought to examine whether a history of PUPO impacts surgical outcomes in males undergoing robotic-assisted inguinal hernia repair.
Methods:
The Americas Hernia Society Quality Collaborative (AHSQC) database was queried to identify male patients who underwent a robotic inguinal hernia repair with 30-day follow-up. A sub-query was performed to identify subjects within the cohort with a documented history of PUPO. Propensity score matching was subsequently utilized to evaluate for differences in intra-operative complications and short-term post-operative outcomes.
Results:
In total, 1664 male patients underwent robotic-assisted inguinal hernia repair, of whom 65 (3.9%) had a PUPO. After a 3:1 propensity score matching with hernia repair patients who did not have prior procedures, 195 (11.7%) males were included in the comparison cohort. There were no documented vascular, bladder, or spermatic cord injuries in either group. There was no difference in 30-day readmission rate (5% vs. 3%, respectively, p = 0.41). No hernia recurrences were recorded within the 30-day follow-up period in either group. There was no statistical difference in post-operative complications (including seroma formation, hematoma, and surgical site occurrences) between the two groups (14% vs. 8%, p = 0.18).
Conclusions:
In an experienced surgeon's hands, robotic-assisted minimally invasive inguinal hernia repair may be an alternative to open repair in patients with PUPO who were previously thought to be poor minimally invasive surgical candidates.
Insights
Robotic inguinal hernia repair is safe and effective for men with prior urologic pelvic operations (PUPO). This minimally invasive approach showed no increased complications or recurrences compared to those without PUPO.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Surgical Outcomes
Background:
- Prior urologic pelvic operations (PUPO) can complicate inguinal hernia repair due to tissue scarring.
- The safety and effectiveness of minimally invasive inguinal hernia repair in patients with PUPO remain debated.
Purpose of the Study:
- To investigate the impact of a history of PUPO on surgical outcomes in males undergoing robotic-assisted inguinal hernia repair.
Main Methods:
- Data from the Americas Hernia Society Quality Collaborative (AHSQC) database was analyzed.
- Male patients undergoing robotic inguinal hernia repair were identified, with a subgroup having PUPO.
- Propensity score matching was used to compare outcomes between groups.
Main Results:
- No significant differences in intra-operative complications (e.g., vascular, bladder, spermatic cord injuries) were observed.
- Short-term outcomes, including 30-day readmission rates and hernia recurrence, were similar between patients with and without PUPO.
- Post-operative complication rates (seroma, hematoma, surgical site occurrences) did not differ significantly.
Conclusions:
- Robotic-assisted minimally invasive inguinal hernia repair is a viable option for patients with PUPO.
- Experienced surgeons can successfully perform this procedure in patients previously considered poor candidates for minimally invasive surgery.
