Use of end-to-end anastomotic sizer with occlusion balloon to prevent loss of pneumoperitoneum in robotic vesicovaginal fistula repair.

Maintaining the pneumoperitoneum in robotic-assisted surgery can be difficult when vaginal integrity is compromised, such as in vesicovaginal fistula. We report an approach using an anastomotic sizer modified with an occlusion balloon for manipulation of the vaginal apex and maintenance of the pneumoperitoneum for robotic-assisted vesicovaginal fistula repair.
