Abstract

Purpose

Pain after bariatric surgery can prolong recovery. This patient group is highly susceptible to opioid-related side effects. Enhanced Recovery After Surgery guidelines strongly recommend the administration of multimodal medications to reduce narcotic consumption. However, the role of ultrasound-guided transversus abdominis plane (USG-TAP) block in multimodal analgesia of weight loss surgeries remains controversial.

Materials and Methods

A systematic search was performed in four databases for studies published up to September 2019. We considered randomized controlled trials that assessed the efficacy of perioperative USG-TAP block as a part of multimodal analgesia in patients with laparoscopic bariatric surgery.

Results

Eight studies (525 patients) were included in the meta-analysis. Pooled analysis showed lower pain scores with USG-TAP block at every evaluated time point and lower opioid requirement in the USG-TAP block group (weighted mean difference (WMD) = − 7.59 mg; 95% CI − 9.86, − 5.39; p < 0.001). Time to ambulate was shorter with USG-TAP block (WMD = − 2.22 h; 95% CI − 3.89, − 0.56; p = 0.009). This intervention also seemed to be safe: only three non-severe complications with USG-TAP block were reported in the included studies.

Conclusion

Our results may support the incorporation of USG-TAP block into multimodal analgesia regimens of ERAS protocols for bariatric surgery.
