Abstract

Background

Transversus abdominis release (TAR) is a safe, effective strategy to repair complex ventral incisional hernia (VIH); however, open TAR (o-TAR) often necessitates prolonged hospitalization. Robot-assisted TAR (r-TAR) may benefit short-term outcomes and shorten convalescence. This study compares 90-day outcomes of o-TAR and r-TAR for VIH repair.

Methods

A single-center, retrospective review of patients who underwent o-TAR or r-TAR for VIH from 2015 to 2016 was conducted. Patient and hernia characteristics, operative data, and 90-day outcomes were compared. The primary outcome was hospital length of stay, and secondary metrics were morbidity, surgical site events, and readmission.

Results

Overall, 102 patients were identified (76 o-TAR and 26 r-TAR). Patients were comparable regarding age, gender, body mass index, and the presence of co-morbidities. Diabetes was more common in the open group (22.3 vs. 0%, P = 0.01). Most VIH defects were midline (89.5 vs. 83%, P = 0.47) and recurrent (52.6 vs. 58.3%, P = 0.65). Hernia characteristics were similar regarding mean defect size (260 ± 209 vs. 235 ± 107 cm², P = 0.55), mesh removal, and type/size mesh implanted. Average operative time was longer in the r-TAR cohort (287 ± 121 vs. 365 ± 78 min, P < 0.01) despite most receiving mesh fixation with fibrin sealant alone (18.4 vs. 91.7%, P < 0.01). r-TAR trended toward lower morbidity (39.2 vs. 19.2%, P = 0.09), less severe complications, and similar rates of surgical site events and readmission (6.6 vs. 7.7%, P = 1.00). In addition, r-TAR resulted in a significantly shorter median hospital length of stay compared to o-TAR (6 days, 95% CI 5.9–8.3 vs. 3 days, 95% CI 3.2–4.3).

Conclusions

In select patients, the robotic surgical platform facilitates a safe, minimally invasive approach to complex abdominal wall reconstruction, specifically TAR. Robot-assisted TAR for VIH offers the short-term benefits of low morbidity and decreased hospital length of stay compared to open TAR.
