Conventional Epidural vs Transversus Abdominis Plane Block with Liposomal Bupivacaine: A Randomized Trial in Colorectal Surgery

Transversus abdominis plane block was associated with a 0.5-day reduction in length of stay in a standardized ERP compared with epidural. Early indication favors TAP in patients with a history of postoperative urinary retention, as a trend of urinary retention was associated with epidural. Transversus abdominis plane block offers an effective alternative to epidural in colorectal surgery, regardless of operative approach.
