Abstract
OBJECTIVE
To explore whether TachoSil, a hemostatic patch, can reduce the incidence of lymphocele formation. Development of a lymphocele is a frequent complication after pelvic lymph node dissection (PLND) for nodal staging in prostate cancer.
MATERIALS AND METHODS
From 2013 to 2017, 100 patients with prostate cancer who were set to undergo a staging PLND before external beam radiotherapy (n = 50) or PLND concomitant with radical prostatectomy (RP) (n = 50) were prospectively randomized 1:1 between bilateral TachoSil placement or nonplacement. Primary end points were radiographic lymphocele development, lymphocele volume (1 week and 1 month postoperatively), and the duration and volume of postoperative catheter drainage.
RESULTS
Patient, tumor, and surgical characteristics of the TachoSil and the control groups did not differ significantly. In total, 65 patients (65%) experienced a radiographic lymphocele up to 3 months after surgery: 29 (58%) in the TachoSil group and 36 (72%) in the control group (P = .34). Significantly less radiographic lymphoceles were observed 1 week postoperatively for patients who underwent sole PLND and 1 month postoperatively for patients who underwent PLND with RP in the TachoSil group compared with the control group (16% vs 48%, P = .024, and 24% vs 52%, P = .047, respectively). The other postoperative characteristics presented no significant differences between the 2 groups, neither for patients undergoing sole PLND nor for patients undergoing PLND with RP.
CONCLUSION
Patients undergoing bilateral TachoSil placement after PLND seem less likely to develop a radiographic lymphocele early postoperatively. Nevertheless, the clinical relevance of the use of TachoSil remains highly debatable.
