Purpose:
To assess the impact of three-dimensional (3D) vision use on operative time (OT) in laparoscopic Roux-en-Y gastric bypass (LRYGB) with hand-sewn anastomoses.
Methods:
We analyzed a prospectively collected database of patients who underwent LRYGB. We included all patients operated on with either 2D or 3D vision. Demographics and clinical characteristics, operative time, hospital stay and 30-day postoperative complications were collected for all patients and analyzed.
Results:
During the study time, out of 143 patients who underwent LRYGB for morbid obesity, 111 were considered eligible. Seventy-eight patients were operated with 2D vision and 33 patients with 3D vision. Demographics and clinical characteristics were not different among groups. Mean OT was 203±51 and 167±32 minutes in the 2D and 3D groups respectively (p<0.001). Multivariate analyses showed that increasing age and BMI were independently related to prolonged OT, while 3D vision (OR 6.675, 95% CI 2.380-24.752, p<0.001) was strongly associated with shorter OT.
Conclusions:
The use of 3D vision in LRYGB significantly reduced the OT, though intra- and postoperative complication rates and the length of hospital stay were not affected. Despite its limitations, our study supports the value of 3D vision laparoscopy in bariatric surgery.
