Objectives: To describe surgical characteristics of stage I-IIA non-small cell lungcancer.Subjects and methods: An uncontrolled intervention study on 83 patients diagnosedwith stage I - IIa non-small cell lung cancer who underwent thoracoscopy at MilitaryHospital 175 from January 2015 to December 2020.Results: The average surgical time in the study was 137.5 minutes and the blood losswas not much. Small incisions have an average length of 2.95cm, high aesthetics andlow postoperative pain (5.92 days). The patient had a tumor that pulled the visceralpleura 62/83 (74.7%); 21/83 (25.3%) patients with tumors located in parenchyma;6/83 (7.2%) patients had lung adhesions to the chest wall. There were 2 (2.4%) patientswith bleeding complications that required conversion to open surgery; After surgery,there were 7 complications including 1 (1.2%) pneumonia; 1 (1.2%) empyema causedby green pus bacilli; 5 (6.0%) cases of gas leak lasting more than 7 days.Conclusion: Tumor characteristics in surgery include features of tugging visceralpleura, tumor located in parenchyma, lung sticking to chest wall. Commoncomplications include bleeding. Complications after surgery include pneumonia,empyema caused by green pus bacilli, prolonged gas.

Objective: To describe the characteristics of work related musculoskeletal disorders in commandos. Subjects and methods: A cross-sectional descriptive study on 1,500 servicemen of the comando forces participating in the investigation of musculoskeletal disorders. Results: The prevalence of chronic musculoskeletal pain (in 12 months) was 60% of which the pain was mainly found in the nape, shoulder and lower back. Chronic musculoskeletal pain having to leave work only had a low rate (17,73%), most in the lower back with 9.40%. The nape and lower back had the highest rate of acute musculoskeletal pain, 21.40% and 21.27%, respectively. The Comandos soldiers worked mainly in standing and sitting positions. High REBA scores associated with musculoskeletal pain in the neck, elbows, wrists or hands, upper and lower back, thighs, and knees. Conclusion: The rate of musculoskeletal disorders in the commandos was 60%, of which the nape, shoulder, and lower back are the areas with the highest rate of musculoskeletal pain. Standing and sitting are the two main working positions of commandos. High REBA scores are associated with musculoskeletal pain in commandos.
