Abstract    Objective    To investigate the effect and value of presacral continuous low negative pressure irrigation and drainage in promoting the recovery of presacral residual cavity and perineal incision after resection of presacral cyst tumors. Methods    The clinical data of 130 patients with presacral cyst tumors who underwent the presacral cyst tumor resection at the Affiliated Tumor Hospital of Zhengzhou University from January 2014 to January 2021 were reviewed; Acording to the different method of presacral drainage,  patients were divided into presacral continuous low negative pressure irrigation and drainage group(67 cases) and  traditional presacral drainage group(63 cases) to compare the the incidence and treatment effects of postoperative presacral residual cavity, perineal incision complications, as well as the treatment effects of postoperative presacral residual cavity and perineal incision infection. Results    The incidence of perineal incision infection and presacral effusion in the presacral continuous low negative pressure irrigation and drainage group were significantly lower than those in the traditional drainage group ［3 patients (4.5%) vs. 10 patients (15.9%), 1 patient (1.5%) vs. 7 patients (11.9%); all P＜0.05］; The recovery time of presacral residual cavity and the healing time of presacral residual cavity and perineal incision in the presacral continuous low negative pressure irrigation and drainage group were significantly shorter than that in the traditional drainage group［14 (12, 24) vs 16 (14, 40) days，12 (10, 28) vs 14 (12, 48) days; all P＜0.05］. The total 21 patients accured the presacral residual cavity and perineum infection after operation in the two groups; The rate of incision removal and drainage treatment in the presacral continuous low negative pressure irrigation and drainage group was significantly lower than that in the traditional presacral drainage group［(0 patient (0) vs 10 patients (58.8%), P<0.05)］, and the recovery time of infection symptoms in presacral residual cavity and perineal incision was also significantly shorter than that in traditional presacral drainage group (5.0 ± 1.4) days vs. (7.2 ± 2.6) days, P<0.05. Conclusion    The continuous presacral negative pressure irrigation and drainage can reduce the incidence of presacral effusion and perineal incision infection and promote the recovery of presacral residual cavity and perineal incision in the patients who received the presacral cyst resection.
