Application of barbed absorbable suture line in retroperitoneoscopic partial nephrectomy / 肿瘤研究与临床

ABSTRACT

Objective To investigate the safety and feasibility of barbed absorbable suture line in retroperitoneoscopic partial nephrectomy. Methods 45 patients who were suitable for retroperitoneoscopic partial nephrectomy from February 2013 to February 2014 were collected and randomly divided into V-Loc group and the control group. 23 cases of V-Loc barbed absorbable suture line were chosen by suture kidney in V-Loc group.There were 22 cases of coated vicryl plus antibacterial suture and Hem-o-lok clip in the control group. The differences of operative time, blood loss, warm ischemia time, suture time, hospital stay and suture material costs were compared respectively between the two groups. Results All 45 cases of retroperitoneoscopic partial nephrectomy were successfully performed, without conversion to open surgery and important intraoperative complications. Postoperative pathology report showed that there were 37 cases with renal clear cell carcinoma, 3 cases with papillary renal cell carcinoma, 2 cases with chromophobe renal cell carcinoma with negative surgical margin, 3 cases with renal angiomyolipomas. In the V-Loc group and the control group, the average operative time were (90.8±9.6) and (96.9±9.1) min (P>0.05), the mean blood loss were (80.4±24.2) and (99.5±24.8) ml (P>0.05), the mean warm ischemia time were (21.5±3.4) and (25.3±1.9) min (P0.05), the average cost of renal parenchymal suture material were (1 215.5±101.4) and (2 073.5±301.8) yuan (P<0.05). The warm ischemia time,suture time and suture material costs in the V-Loc group were significantly lower than those in the control group (all P<0.05). Conclusion The application of barbed absorbable suture line in retroperitoneoscopic partial nephrectomy can shorten warm ischemia time and suture time, and save hospitalization costs, with favorable safety and feasibility.
