The even number of files will be in block A and the odd number in block B. To read counting numbers from top to bottom. Out of 80 randomly selected patients, 40 patients will be implanted in block A before the onset of epidural catheter anesthesia from the thoracic space and an epidural analgesic pump with local anesthetic will be implanted for patients around the end of the operation and 40 patients in block B After anesthesia and surgery near the end of the operation, a venous pump was connected to the peripheral vein for the patients and the patients will undergo intravenous infusion of narcotics and ketorolac. At the end, the two groups will be compared in terms of pain control and short-term complications. 2-3 Control of pain and complications after surgery in esophageal cancer patients. Intervention 1: Intervention group: Patients who have had a thoracic catheter implanted before the epidural anesthesia and an epidural analgesic pump with a local anesthetic will be inserted around the end of the operation. Intervention 2: Intervention group: Patients who after anesthesia and surgery near the end of the venous pump from the peripheral vein is connected to the patient and the patient will undergo intravenous infusion of narcotics and ketorolac.
