Concurrent Inguinal Hernia Repair in Patients Undergoing Minimally Invasive Radical Prostatectomy: A National...

To compare perioperative 30-day outcomes between minimally invasive radical prostatectomy (MIRP) with and without concurrent inguinal hernia repair (IHR) using a national database.

The National Surgical Quality Improvement Program database was queried for MIRP from 2012 to 2015. Concurrent IHR was identified using relevant Current Procedural Terminology codes. Primary outcomes were overall complications, reoperations, unplanned readmissions, and mortality within 30 days of MIRP. Secondary outcomes included operative time (OT), length of stay (LOS), prolonged length of stay (PLOS, >2 days), and discharged to continued care (DCC). Multivariable logistic regression was performed to identify the association between concurrent IHR and outcomes.

A total of 18,065 patients were included; 375 (2.1%) had concurrent IHR. The unadjusted comparison showed no significant difference in overall complication, reoperation, unplanned readmission, or mortality rates between MIRP+IHR and MIRP only groups. OT was longer in the MIRP+IHR group (229 vs 195 minutes, p < 0.001) but no differences were found in LOS, PLOS, or DCC rates. Multivariable logistic regression showed concurrent IHR was not associated with increased odds of overall complication (odds ratio [OR] = 0.83, 95% confidence interval [CI] = 0.49-1.40, p = 0.479), reoperation (OR = 0.57, 95% CI = 0.14-2.30, p = 0.426), unplanned readmission (OR = 0.92, 95% CI = 0.51-1.64, p = 0.771), PLOS (OR = 1.19, 95% CI = 0.86-1.63, p = 0.297), or DCC (OR = 1.94, 95% CI = 0.70-5.34, p = 0.202).

Concurrent IHR with MIRP was associated with longer OT, but there were no increased 30-day adverse outcomes within the National Surgical Quality Improvement Program (NSQIP) database. These data support the safety of performing concurrent IHR at the time of MIRP and it should be considered to spare men an additional procedure.
