RESUMEN

Abstract 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.

RESUMEN

Abstract Purpose: To identify the surgical trainee benefits through the use of video assisted training (VAT). Methods: Twelve cases of uncomplicated laparoscopic cholecystectomy (LC) were selected. Edited video segments focused on essential intra-operative anatomical structure identification and critical surgical steps. Evaluation of these videos was constructed on a scoring system based on pre and post-teach tests. Results: The mean value of the pre-teach score was 33.2 ± 18.0 points and in the post-teach test the mean value was 66.7 ± 9.7 points. A statistically significant difference was seen when comparing pre and post-teach results (p<.00001). Conclusion: The widespread and the systematic use of video assisted learning may be a useful and economic tool in adjunct to the surgical training techniques practiced until now throughout the surgical community.
