Robotic repair of moderate-sized midline ventral hernias reduced complications, readmissions, and length of hospitalization compared to open techniques.

PURPOSE

To compare outcomes of robotic and open repair for uncomplicated, moderate-sized, midline ventral hernias.

METHODS

From 2017 to 2021, patient characteristics and 30 day outcomes for all ventral hernias at our center were prospectively collected. We studied hernias potentially suitable for robotic repair: elective, midline, 3-10 cm rectus separation, no prior mesh, and no need for concomitant procedure. Robotic or open repair was performed by surgeon or patient preference. The primary outcome was any complication using Clavien-Dindo scoring. Secondary outcomes were operative time, length-of-stay, and readmissions. Regression identified predictors of complications.

RESULTS

Of 648 hernias repaired, 70 robotic and 52 open repairs met inclusion criteria. The groups had similar patient demographics, co-morbidities, and hernia size, except that there were more immunosuppressed patients in the open group (11 versus 5 patients, p = 0.031). Complications occurred after 7 (13%) open repairs versus 2 (3%) robotic repairs, p = 0.036. Surgical site infection occurred after four open repairs but no robotic repair, p = 0.004. Length-of-stay averaged almost 3 days longer after open repair (4.3 ± 2.7 days versus 1.5 ± 1.4 days, p = 0.031). Readmission occurred after 6 (12%) oppen repairs but only 1 (1%) robotic repair. A long-term survey (61% response rate after mean follow-up of 2.8 years) showed that the HerQLes QOL score was better after robotic repair (46 ± 15 versus 40 ± 17,  = 0.049). In regression models, only open technique predicted complications.

CONCLUSIONS

Robotic techniques were associated with fewer complications, shorter hospitalization, fewer infections, and fewer readmissions compared to open techniques. Open surgical technique was the only predictor of complications.
