A Novel Technique for Bladder Wall Fixation in Pneumovesicoscopic Surgery: T-Bar.

Abstract

Background: As a relatively new approach, popularity of pneumovesicoscopic surgery is increasing, but slower than expected due to complex nature of the procedure with efforts to overcome the difficult steps of the procedure. Bladder fixation is one of the crucial steps of the procedure. In this study, we present a novel and simple T-bar technique to overcome this difficulty. Methods: We retrospectively evaluated 24 consecutive patients (39 ureters) who underwent pneumovesicoscopic surgery with fixation of the bladder wall between December 2017 and September 2019. Results: Fixation by transabdominal suture (TS) was performed in 3 patients, while fixation by thread loops with needle in 3 and T-bar device in 18. Tearing of the bladder wall was encountered in 2 patients in TS, in 2 patients with thread loop groups, but none in the T-bar group. Conversion to open surgery was necessary in 3 patients in the T-bar group, but only 1 was related with the fixation technique. Conclusions: T-bar technique is an inexpensive and simple solution providing stable and reliable bladder wall and working port fixation during pneumovesicoscopy.
