Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric surgery performed in North America. As our knowledge of the importance in limiting narcotic use in postoperative patients increases, we sought to evaluate the effect of transversus abdominis plane (TAP) blocks on inpatient narcotic use in patients undergoing LSG. Methods: A retrospective review of LSG performed at a single institution by 3 bariatric surgeons was performed. All cases over a 15-month period were included, and anesthesia records were reviewed to stratify patients that received a TAP block and those that did not. Demographic, as well as surgical, outcomes were collected for all patients. Narcotic utilization, as reported in morphine equivalents (ME), was evaluated between the 2 groups. Results: 384 LSG patients were identified, of which 37 (9.6%) received a TAP block. There was no statistically significant difference in postoperative morbidity, length of stay, or readmission between groups. Median narcotic utilization in hospital days 1 and 2 in patients with TAP blocks was 49 ME (Interquartile Range (IQR) 14.5-84.5) to 82.5 ME (IQR 57.4-106) in the no-TAP group (P <.001). After controlling for multiple demographic- and patient-related cofactors, multiple linear regression analysis demonstrated TAP block patients utilized 22.48 ME less than the no-TAP group (P <.001) in the first 2 days of their hospitalization. Discussion: Patients that received a TAP block as a part of their perioperative anesthetic care utilized less in-hospital narcotics than those patients that did not receive a TAP block. TAP blocks should be considered as part of a multimodal pain control strategy for patients undergoing LSG.
