Transversus abdominis plane (TAP) block is a peripheral nerve block directed at the nerves in the anterior abdominal wall. We sought to determine whether TAP block reduces post-operative narcotic use or length of stay after open gynecologic surgery. Among 98 women who underwent an open hysterectomy between July 2016 - July 2017 by a gynecologic oncologist, 73 (74.5%) received a TAP block. The majority of patients who received a TAP block had a vertical incision (86.3%) while the majority of patients who did not receive TAP block had a transverse incision (64%). More patients in the TAP block group underwent cancer debulking compared to the no TAP block group (65.7% versus 8%). The two groups did not differ in post-operative pain scores on day 1, 2, or 3, cumulative narcotic use by post-operative day 3, length of stay, or ileus. We found TAP block after vertical skin incision results in comparable pain scores, narcotic use, and length of stay compared to patients undergoing transverse incisions without TAP block.
