Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has a reported learning curve of 100 cases. Robotic-assisted surgery decreases the learning curve in complex laparoscopic surgeries. We hypothesize that robotic-assisted, hand-sewn gastrojejunostomy during a LRYGB will improve results during the initial 100 cases when compared with the literature. Methods: Our first 100 robotic-assisted gastrojejunostomies performed during LRYGB were reviewed from a prospective database. Patient demographics, operative times, length of stay, reoperations, anastomotic leak, pulmonary embolus, and death were all evaluated. Results: The mean age and body mass index were 42 and 50, respectively. Operative times ranged from 148 minutes to 437 minutes (mean = 254). There were no leaks or deaths. Four patients had complications, including reoperation (1), incisional hernia (1), pulmonary embolus (1), and recurrent umbilical hernia (1). Conclusions: Robotic-assisted LRYGB is feasible and safe, as evidenced by the excellent outcomes from this series during the initial learning curve for LRYGB.
