The ultrasound-guided transversus abdominis plane (TAP) block can be time-consuming, costly, and technically challenging in the bariatric patient population. Laparoscopic-assisted TAP (L-TAP) block was developed and has been shown to be non-inferior to ultrasound-guided blocks. Postoperative pain can be significant, and pain control in the morbidly obese patients can be challenging. This study's aim was to compare L-TAP block to traditional port site infiltration in terms of postoperative opioid requirement for morbidly obese patients after laparoscopic Roux-en-Y gastric bypass (RYGB) surgery.
