Reduction in postoperative ileus rates utilizing lower pressure pneumoperitoneum in robotic-assisted radical prostatectomy

Abstract

Robotic-assisted radical prostatectomy (RARP) is the most commonly performed surgery for prostate cancer. This is a study comparing differences in postoperative outcomes between pneumoperitoneum pressures of 15 mmHg and 12 mmHg. Retrospective chart review was performed on 400 patients undergoing RARP over a 5 year period. A combination of Fisher's exact test and ANOVA were utilized for statistical analysis. Age, BMI, Gleason score, positive margin rate, complication rates, blood loss, and operative times were similar in both groups. Length of stay and postoperative ileus rates were significantly less in the 12 mmHg group (p < 0.05). RARP can be safely performed utilizing a lower pressure pneumoperitoneum. Decreasing insufflation pressures from 15 to 12 mmHg can further lead to decreased rates of postoperative ileus.
