Our goal was to evaluate whether TAP block offers the same analgesic pain control compared to epidural technique in laparoscopic radical prostatectomy surgery through the morphine consumption in the first 48 hours.

In this study, 45 patients were recruited and assigned to either TAP or epidural. The main study outcome was morphine consumption during the first 48 hours after surgery. Other data recorded were pain at rest and upon movement, technique-related complications and adverse effects, surgical and postoperative complications, length of surgery, need for rescue analgesia, postoperative nausea and vomiting, start of intake, sitting and perambulation, first flatus, and length of in-hospital stay.

From a total of 45 patients, two were excluded due to reconversion to open surgery (TAP group = 20; epidural group = 23). There were no differences in morphine consumption (0.96 vs. 0.8 mg; p = 0.78); mean postoperative VAS pain scores at rest (0.7 vs. 0.5; p = 0.72); or upon movement (1.6 vs. 1.6; p = 0.32); in the TAP vs. epidural group, respectively. Sitting and perambulation began sooner in TAP group (19 vs. 22 hours, p = 0.03; 23 vs. 32 hours, p = 0.01; respectively). The epidural group had more technique-related adverse effects.

TAP blocks provide the same analgesic quality with optimal pain control than epidural technique, with less adverse effects.
