Background:
Chronic post-thoracic surgery pain (CPTSP) is a common complication that affects a patient's quality of life. Thoracotomy is associated with a high risk of chronic pain. Video-assisted thoracoscopy surgery (VATS) is a less traumatic option, but its role in the development of CPTSP is unclear. Regardless of the approach, there is evidence that demographic, psychosocial, or clinical factors also contribute to pain. The primary objective of this study is to determine the incidence of CPTSP in our hospital. The secondary objective is to identify possible risk factors related to CPTSP.
Method:
Retrospective, single-centre observational study. The medical records of patients that underwent thoracic surgery between January 2016 and January 2020 were reviewed. The diagnosis of CPTSP was made by reviewing the postoperative visits 6 months after surgery. We analysed the relationship between CPTSP and a series of variables, and then constructed a multivariate binary logistic regression model with a significance level of p < 0.05.
Results:
A total of 259 patients were analysed, 46.7% underwent VATS and 53.3% underwent thoracotomy. The overall incidence of CPTSP was 12%; 4.1% in VATS and 18.8% in thoracotomies. The multivariate model revealed that moderate-to-severe acute postoperative pain and a greater number of chest tubes were risk factors for CPTSP.
Conclusion:
The incidence of CPTSP was 12% in our hospital. Patients with higher acute postoperative pain severity and several chest tubes were more likely to develop CPTSP.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
