[LAPAROSCOPIC SINGLE-SITE SURGERY FOR URACHAL REMNANT USING THE GLOVE PORT]

(Objectives) Trans-umbilical laparo-endoscopic single-site surgery for a urachal remnant (LESSU) enables an aesthetically outcome as the scar is concealed within the umbilical fold. We performed trans-umbilical LESSU using the glove port to minimize interference between surgical instruments and evaluated its efficacy. (Materials and methods) LESSU was performed by a single surgeon in our institute in 13 patients between August 2020 and April 2023. GelPOINT Mini™ (Applied Medical Corporation) or Free access XS (TOP^® Corporation) were used in the first two cases, followed by the glove port method from the third case onward. We retrospectively collected clinical data by using medical records. (Results) Five males and six females, with a median age of 33 years (23-74 years), underwent surgery with the glove method. The median operating time was 126 minutes (84-153 minutes), and minimal blood loss was observed in all cases. Perioperative complications occurred in one case (forcal peritonitis, Clavien-Dindo II). The median postoperative hospital stay was 3 days (2-5 days). Fixation using a rubber band attached to a camera port from the fifth case onwards, contributed to reduced average operating time. The surgical cost of surgery using the glove method was lower than using standard surgical platforms for single-port surgery. (Conclusion) LESSU using the glove method has several benefits such as offering better flexibility of each surgical instrument, better surgical imaging near the umbilicus, and treatment at a lower surgical cost.
