Comparative study of self-retaining suture versus traditional absorbable suture in laparoscopic partial nephrectomy

Abstract

Objective To evaluate the safety and efficacy of QUILLTM self-retaining suture (QUILLTMSRS) in laparoscopie partial nephrectomy.Methods Sixty-three patients (39 males,24 females) with renal tumor accepted laparoscopic partial nephrectomy in Peking Union Medical Hospital from February 2012 to January 2013.The ages ranged from 38 to 75 years.The tumor sizes varied from 1.5 cm to 4.5 cm.According to the device of renorrhaphy,they were divided into 2 groups.Vicryl suture was used for renorrhaphy in 32 patients (Group 1),and QUILLTMSRS was used in 31 patients (Group 2).Renorrhaphy was performed in two layers for both groups,with a closure of deep vessels and the collecting system with 4-0 absorbable suture,followed by a running closure of the renal parenchyma and renal capsule.Demographical and perioperative parameters including age,body mass index,tumor size,R.E.N.A.L score,estimated blood loss,warm ischemic time,length of hospital stay were recorded and compared between the 2 groups.Results Renorrhaphy was successfully performed in all the 63 cases without conversion to open procedure or nephrectomy.The estimated blood loss and length of postoperative hospital stay were not significantly different between the 2 groups (P＞0.05).But warm ischemic time was significantly shorter in QUILLTM SRS group than that in Vicryl group (22.2 vs 26.7 min,P＜0.001).Conclusions QUILLTMSRS could be safe and effective for renorrhaphy in laparoscopic partial nephrectomy.It could make laparoscopic renorrhaphy easier and reduce warm ischemic time significantly.
