While thoracic epidural analgesia (TEA) is considered first-line for postoperative analgesia after esophagectomy, complications can arise related to its sympathectomy and mobility impairment. Additionally, it has been shown that postoperative outcomes are improved with early extubation following esophagectomy.

The axillary block is considered to be the safest and with fewer adverse events compared to the interscalene (eg, phrenic nerve block, spinal cord or vertebral artery puncture) and supraclavicular (eg, pneumothorax). However, with regard to postoperative neurological symptoms (PONS), it is controversial whether its incidence after an axillary block was higher than that after non-axillary approaches”. In this study, we investigated whether the incidence of a neuropathy after an axillary block was higher than that after non-axillary approaches. Patients and Methods This was a single-center, retrospective cohort study. All UGBPBs were performed under general anesthesia between January 2014 and March 2020. The outcomes included the overall incidence of PONS and neuropathies for axillary and non-axillary approaches. The etiology, symptoms, and outcomes of patients were investigated.
