To investigate the clinical application of QuillTM self-retaining system in patients undergoing laparoscopic partial nephrectomy.

A retrospective analysis was conducted on the clinical data of 38 patients with renal neoplasms undergoing laparoscopic partial nephrectomy, who were admitted to the People's Hospital of Tibet Autonomous Region from June 2015 to January 2020. According to the suture used for renorrhaphy, the patients were divided into two groups. Vicryl suture was used for renorrhaphy in 20 patients (group 1), and QuillTM was used in 18 patients (group 2). Renorrhaphy was performed in two layers for both groups. In group 2, 2-0 QuillTM was used to suture the deep wound bed, and the second outer layer renorrhaphy was performed with I-0 QuillTM in the same way. In group 1, the inner layer was sutured using 2-0 Monocryl suture by the same method mentioned above. A second outer layer was sutured with 1-0 absorbable suture across the wound. The operation time, warm ischemia time, intraoperative blood loss, and postoperative complications were compared between the two groups.

Renorrhaphy was successfully performed in all the 38 cases without conversion to open procedure or nephretomy. The estimated blood loss and average operation time did not differ significantly between the two groups (P>0.05), although warm ischemic time was significantly shorter in the QuillTM group than in the Vicryl group [15±4) min vs (25±5) min, t=3.32, P=0.002]. There were no intraoperative complications in either group. One patient in the Vicryl suture group underwent selective renal artery embolization due to postoperative hemorrhage, and one patient was left with a D-J tube for leaking urine. There was no postoperative complication in the QuillTM suture group.

QuillTM is safe and effective for renorrhaphy in laparoscopic partial nephrectomy. The suture time, warm ischemic time, and the incidence of postoperative complications can be reduced by using the QuillTM suture in operation.
