Abstract: Objective · To explore the safety and feasibility of using sutureless technique of argon beam coagulator in laparoscopic partial nephrectomy. Methods · A total of 10 patients receiving laparoscopic partial nephrectomy with argon beam coagulator in Shanghai Ninth Peoples Hospital, Shanghai Jiao Tong University School of Medicine October 2016 to October 2017 were selected. The clinical efficacy and safety of the operation was retrospectively analyzed. Results · The average age of the 10 patients was 50.4 (24.0-73.0)years, the average size of the tumor was 2.1 (1.5-2.5)cm, and the average RENAL score was 5. All of the 10 patients underwent intraoperative renal artery occlusion. Intraoperative scissors were used to completely remove the tumor and remove the tumor bed after the resection. Then the argon beam coagulator was repeatedly used for hemostasis. After hemostasis was completed, the hemostatic gauze was covered on the surface of the tumor bed. The mean operation time was 95.0 (60.0-108.0) min, and the average thermal ischemia time of the renal artery occlusion was 7.8 (5.5-10.0) min. The average blood loss was 86 (50-150) mL during the operation. The average decrease of hemoglobin was 11.8 (3.0-22.0) g/L on the first day after operation. The mean indwelling catheterization time was 2.7 (1.5-3.5)d, the average time of hospitalization was 5.2 (4.0-7.0) d, the extraction time of drainage tube after operation was 2.6(1.0-4.0) d, and the flow rate was 38.5 (10.0-80.0) mL. Conclusion · Argon knifes pray coagulation has good efficacy and safety in patients with renal tumor renal resection, especially for some exophytic renal tumors, which has short operation time, less damage of hot ischemia, good postoperative effect, no increase in hospitalization time after surgery, reduced economic burden of the patients, being worthy of popularization and application.
