The Safety and Efficacy of Adjuvant Hemostatic Agents During Laparoscopic Nephron-Sparing Surgery: Comparison of Tachosil and Floseal Versus No Hemostatic Agents.

Purpose: To compare the effectiveness of TachoSil and Floseal during laparoscopic nephron-sparing surgery (LNSS), and to evaluate postoperative complications, especially hemorrhage and urinary leakage. Materials and Methods: The medical records of all patients that underwent LNSS for a small renal mass (SRM) performed by the same experienced surgeon were retrospectively analyzed. The patients were divided into the following 3 groups, based on hemostatic agent: group 1: no adjuvant hemostatic agent (no AHA); group 2: TachoSil; group 3: Floseal. Results: The study included 79 patients; no AHA group: n = 18; TachoSil group: n = 25; Floseal group: n = 36. The 3 groups were similar in terms of diameter [29.6 ± 11.5 mm, 26.4 ± 13.4 mm and 30.4 ± 9.6 mm, respectively (P = .218)] and PADUA scores [6.9 ± 0.9, 6.7 ± 1 and 6.9 ± 0.9, respectively (P =.540)]. Mean duration of surgery was significantly shorter in the Floseal group (120.9 ± 23.1 minutes) than in the no AHA group (156.6 ± 34.4 minutes). Mean ischemia time was longest in the no AHA group (24.3 ± 4 minutes) and shortest in the Floseal group (21.3 ± 4.3 minutes). Intra-abdominal (IA) catheter drainage on postoperative day 1 was significantly higher in the no AHA group than in the TachoSil and Floseal groups [156.9 ±78.3 mL vs. 72.6 ± 64.5 and 60.8 ± 30.2 mL, respectively (P < .05)]. Mean duration of hospitalization was 3.2 ± 0.5 days in the no AHA group that was significantly longer than in the Floseal group (2.8 ± 0.7 days) (P = .043). There were not any differences in intraoperative complications, the transfusion rate, surgical margin positivity, or postoperative complications between the 3 groups (P = .596, P = .403, P = 1.0, P = .876, respectively). However, pseudoaneurism as a late term complication occurred in 27.7% patients in the no AHA group. Conclusion: TachoSil and Floseal are safe and effective adjuvant treatments for patients undergoing LNSS. They might be useful especially in preventing pseudo aneurisms, shortening intraoperative ischemia time and hospital stay and decreasing postoperative drainage. Shortened operation and warm ischemia time may also be attributed to long learning curve of LNSS. [ABSTRACT FROM AUTHOR]
