Effects of different anesthesia methods on perioperative immune function and long-term regression of patients undergoing thoracoscopic radical esophagectomy for esophageal cancer.

Objective: This study investigated the effects of different anesthetic methods on perioperative immune function and long-term regression of patients undergoing thoracoscopic radical surgery for esophageal cancer.

Methods: Data from 147 patients undergoing thoracoscopic radical surgery for esophageal cancer in our hospital from January 2017 to June 2019 were selected for retrospective analysis. Patients were divided into control (intravenous anesthesia combined with an epidural block, n = 83) and observation (intravenous anesthesia combined with a thoracic paravertebral nerve block, n = 64) groups.
