Reducción del tiempo quirúrgico al realizar la gastroyeyunoanastomosis utilizando sistemas de imagen en tercera dimensión en bypass gástrico laparoscópico: estudio prospectivo aleatorizado

Abstract

Copyright: © 2020 Permanyer. Objective: The objective of this study was to compare the total procedure time and task-specific execution time in gastric bypass using a three-dimensional (3D) versus two-dimensional (2D) imaging system. Materials and methods: This study was a prospective and randomized clinical trial. Forty obese patients were randomized into two groups: gastric bypass with 3D imaging system or with conventional 2D system. The primary endpoint was operative time during manual gastrojejunal anastomosis. Data collection was carried out on demographics, comorbidities, operative time in three stages, and complications. The same surgeon performed all surgeries. Two patients were excluded because technical issues were encountered for viewing their videos during the trial. Results: A total of 20 patients in the Laparoscopic Gastric Bypass (LGB) 3D group and 18 in the LGB 2D group were analyzed. There were no significant differences in the pre-operative data. The average procedure time was 16.5 min lower in the 3D group versus the 2D group. Execution time for specific tasks was not statistically significant, except for the gastrojejunal anastomosis, which is routinely performed as a manual anastomosis in our surgery group. There was no complication intra- or post-operative. Conclusions: The use of a 3D imaging system for laparoscopic gastric bypass was associated with a shorter total operative time, especially for the hand-sewn gastrojejunal anastomosis, compared with the 2D imaging system. Objetivo: Comparar el tiempo total del procedimiento y de tareas específicas en bypass gástrico laparoscópico (BGL) utilizando sistemas de imagen 3D y 2D.
