The present study describes the feasibility of robotic-assisted transvesicoscopic VVF repair in an animal model. Two Yorkshire swine underwent robotic-assisted laparoscopic (RAL) VVF repair. With the 4 trocars, an artificial VVF was made in the supratrigonal area and VVF repair was performed in 3 layers as in open VVF repair methods. The mean operation time was 108 minutes. The operation time was prolonged in 1 case due to weak fixation of bladder to anterior abdominal wall. Equipment interference did not occur. Tissue manipulation and suturing were easy. The results of this study suggest that extraperitoneal RAL procedures for VVF repair may be an effective minimally invasive modality with reduced morbidity. A shorter operation time and easy suturing technique were the distinct merits of the extraperitoneal RAL technique. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.
