Study summary

Bariatric surgery effectively produces weight loss and reduces obesity-related comorbidities. Although it is mostly performed with minimally invasive techniques, the patients may still suffer from moderate-to-severe pain immediately after surgery [1]. Opioids remain the first choice for multimodal analgesia in the treatment of postoperative pain. Providing analgesia after bariatric surgery might be challenging due to a high prevalence of obstructive sleep apnea syndrome and the increased sensitivity to respiratory depression triggered by opioid overuse after surgeryThe most common plane block techniques utilized during laparoscopic bariatric surgery are transversus abdominis plane block (TAP), rectus sheath block (RB), the erector spinae plane block (ESPB) and the external oblique intercostal block (EOI). In this study, we have evaluated the auxiliary benefit of these various techniques in reduction of the postoperative in bariatric surgery. patients who had laparoscopic bariatric surgery at VKV American Hospital between January 2019 and December 2021 were reviewed retrospectively.
