Incidence of Chronic Pain After Video-Assisted Thoracic Surgery

Study Overview
=================
Brief Summary
-----------------
Video-assisted thoracic surgery (VATS) is frequently performed in thoracic surgery. It is widely accepted that VATS causes acute pain. Many factors such as postoperative analgesia treatment plan, operation time, number of chest tubes, and duration of chest tube stay can affect acute pain. This acute pain prolongs the discharge time of the patients and increases the frequency of postoperative pulmonary complications and postoperative morbidity. Postoperative acute pain may cause chronic pain in the later period, and may adversely affect the quality of life of the patients. This study, it was aimed to analyze the symptoms of chronic pain in the 1st and 3rd months postoperatively in patients who had undergone VATS.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain scores at 1st months. | Chronic pain symptoms will be assessed using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Neuropathic pain symptoms (Burning, stabbing, electric shock-like pain, tingling, numbness, pins, and needles feeling, hyperalgesia, allodynia, and hypoesthesia) will also be asked to the patients in the 1st month after surgery. | Chronic pain symptoms at 1st months | 
| Pain scores at 3rd months | Chronic pain symptoms will be assessed using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Neuropathic pain symptoms (Burning, stabbing, electric shock-like pain, tingling, numbness, pins, and needles feeling, hyperalgesia, allodynia, and hypoesthesia) will also be asked to the patients in the 3rd month after surgery. | Chronic pain symptoms at 3rd months |
