Should Peritoneal Re-Approximation be Performed After Transperitoneal Robot-Assisted Radical Prostatectomy?

Abstract

Background: The aim of the study is to examine the effect of peritoneal re-approximation or non-approximation on the postoperative course of patients at the end of transperitoneal robot-assisted radical prostatectomy (tRARP).It is also aimed to examine the relationship between peritoneal re-approximation or non-approximation and drain removal time, need for analgesics, passage of flatus, and length of hospital stay. Methods: A total of 247 patients who underwent tRARP by 2 different experienced surgeons were included in the study. At the end of the tRARP procedure, 1 surgeon performed peritoneal re-approximation (Group 1, n = 108), whereas the other performed peritoneal non-approximation (Group 2, n = 139). The effect of the procedures on drain removal time, passage of flatus, need for analgesics, and length of hospital stay were compared between the groups. Results: There was no significant difference between the groups in terms of preoperative parameters including age, body mass index, and preoperative prostate-specific antigen levels (P > .05) (P = .622, P = .126 and P = .591, respectively). No statistically significant difference was found between the two groups in terms of comorbidity, Gleason score, clinical stage, and lymph node dissection (P = .086, P = .344, P = .318, P = .587, respectively). There was no statistically significant difference between the groups in terms of drain removal time, need for analgesics, passage of flatus, and length of hospital stay (P = .095, P = .142, P = 95, P = .389, respectively). Conclusion: This study did not demonstrate any additional postoperative benefit of peritoneal re-approximation. It has been shown that peritoneal re-approximation has no effect on the length of hospital stay, the need for pain relievers, and passage of flatus, drain duration, day. Therefore, we do not recommend re-approximation of the peritoneum.
