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

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. 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,  = 108), whereas the other performed peritoneal non-approximation (Group 2,  = 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. There was no significant difference between the groups in terms of preoperative parameters including age, body mass index, and preoperative prostate-specific antigen levels ( > .05) ( = .622,  = .126 and  = .591, respectively). No statistically significant difference was found between the two groups in terms of comorbidity, Gleason score, clinical stage, and lymph node dissection ( = .086,  = .344,  = .318,  = .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 ( = .095,  = .142,  = 95,  = .389, respectively). 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.
