Purpose:
The first assistant (FA) plays an important role in the operating room for bariatric surgery. The aim of this study was to examine the relationship between the type of FA and operative time (OT) and postoperative outcomes comparing robotic and laparoscopic approaches in bariatric surgery.
Methods And Materials:
The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data for 2016-2019 was queried. Log-normal regression was performed to evaluate the association of FAs and OT variations within and between groups. We used logistic regression to examine the relationship between the type of FA and 30-day outcomes across all procedures and approaches.
Results:
A total of 691,789 patients who underwent robotic (R), and laparoscopic (L) sleeve gastrectomy (SG), Roux-en-Y gastric-bypass (RYGB), and duodenal switch (DS) were included. The percentage variation of OT was higher in the laparoscopic group (L-SG: 8.18%, L-RYGB: 9.88%, and L-DS: 15.00%) compared to the robotic group (R-SG: 2.43%, R-RYGB: 5.76%, and R-DS: 0.80%). There was not a significant difference in 30-day outcomes between laparoscopic and robotic approaches for the same procedures.
Conclusions:
The FA was associated with a decreased variability in OT in the robotic cohort compared to the laparoscopic group with no significant difference in complication rates. These results suggest that the robotic approach may decrease the need for skilled FAs in bariatric procedures.
