Purpose
The purpose of study was to evaluate the safety and hemostatic efficacy of absorbable self-retaining barbed double-needle suture (SRBDS) in transperitoneal LPN for T1 renal neoplasms.
Methods
In total, 75 patients with renal neoplasm masses (< 7 cm) undergoing transperitoneal LPN were collected since January 2018 to October 2019. After tumor resection with a cold Endoscissor, 3-0 and 0 SRBDS was performed for inner and outer running stitches without either hem-o-lok or LapraTy clip, respectively. Patient demographic information, neoplasm characteristics, perioperative factors, and oncologic outcomes were collected and analyzed.
Results
According to our result, Median tumor size and R.E.N.A.L score was 4.69 cm and 7. Median operative time and overall warm ischemia time was 73 min and 13.14 min. Mean estimated blood loss was 67 ml. intraoperative complications was not showing up and no case was switched to open radical nephrectomy. Postoperative pathological assessment confirmed that negative surgical margins. only single patient experienced secondary surgery-related hemorrhage on the fifth day post-operation, and was treated by transfusion and digital subtraction angiography (DSA) highly selective embolization of the bleeding vessel. No patients developed urinoma or urinary fistula. the overall complications were manageable during three-year follow-up period.
Conclusion
SRBDS was a safe and efficient surgical endoscopic suturing technique with low complication rate in T1 renal neoplasms, which might be considered as an alternative to other suturing techniques, tissue sealants and glues for partial nephrectomy in the future.
