Objective The aim of this study was to examine whether intraperitoneal robot-assisted surgery leads to small bowel obstruction (SBO), possibly caused by the formation of intra-abdominal adhesions. Materials and methods In total, 7256 men treated by intraperitoneal robot-assisted radical prostatectomy (RARP) and 9787 men treated by retropubic radical prostatectomy (RRP) in 2005-2012 were identified in the Prostate Cancer data Base Sweden (PCBaSe). Multivariable Cox proportional hazards models were used to calculate the risk of readmission for SBO, SBO-related surgery and admissions due to abdominal pain up to 5 years postoperatively. Results During the first postoperative year, the risk of readmission for SBO was higher after RARP than after RRP [hazard ratio (HR) 1.92, 95% confidence interval (CI) 1.14-3.25] but after 5 years there was no significant difference (HR 1.28, 95% CI 0.86-1.91), and there was no difference in the risk of SBO surgery during any period. The risk of admission for abdominal pain was significantly increased after RARP during the first year (HR 2.24, 95% CI 1.50-3.33) but not after 5 years (HR 1.23, 95% CI 0.92-1.63). Conclusion Intraperitoneal RARP had an increased risk of SBO and abdominal pain in the short term during the first year, but not in the long term, compared to RRP.
