V905: Needlescopic-Assisted Laparoendoscopic Single-Site Pyeloplasty: Technique and Outcome.
VideoIntroduction and Objectives
To present the technique and outcome of needlescopic-assisted Laparoendoscopic single-site surgery pyeloplasty (LESS-P).
A total number of 18 patients underwent LESS-P. For the performance of the procedure, a multi-port was inserted in the umbilicus and two needlescopic instruments (3mm) were inserted under the costal margin on the mid-clavicular line and on the mid-axillary line at the level of the umbilicus. The steps of the procedure were similar to conventional laparoscopic pyeloplasty. The needlescopic instruments were used for the performance of all steps of the procedure. The multi-port was useful for inserting instruments larger than 3mm and additional instruments of larger than 3mm diameter. Peri-operative data were prospectively collected.
Peri-operative data of the patients that underwent LESS-P is summarized in Table 1. All surgical tasks were performed without significant ergonomic issues due to the triangulation of 3mm instruments. The smaller size of needlescopic instruments required more accuracy for their manipulation. The use of small suturing needle (5-0 Vicryl) for the anastomosis was possible. The andominal scars by the insertion of the needlescopic instruments were practically invisible.
LESS pyeloplasty was efficiently performed when needlescopic instruments are routinely used and shows a different perspective for scarless surgery.
