RESUMO
Background: In our study, we aimed to evaluate the length of hospital stay and complication rate of patients before and after application o f t he E nhanced R ecovery A fter S urgery ( ERAS) protocols. Methods: Between January 2001 and January 2021, a total of 845 patients (687 males, 158 females; mean age: 55±11 years; range, 19 to 89 years) who were operated with the diagnosis of non-small cell lung carcinoma were retrospectively analyzed. The patients were divided into three groups as follows: patients between 2001 and 2010 were evaluated as pre-ERAS (Group 1, n=285), patients between 2011 and 2015 as preparation for ERAS period (Group 2, n=269), and patients who had resection between 2016 and 2021 as the ERAS period (Group 3, n=291). Results: All three groups were similar in terms of clinical, surgical and demographic characteristics. Smoking history was statistically significantly less in Group 3 (p=0.005). The forced expiratory volume in 1 sec/forced vital capacity and albumin levels were statistically significantly higher in Group 3 (p<0.001 and p=0.019, respectively). The leukocyte count and tumor maximum standardized uptake value were statistically significantly higher in Group 1 (p=0.018 and p=0.014, respectively). Postoperative hospitalization day, complication rate, and intensive care hospitalization rates were statistically significantly lower in Group 3 (p<0.001). The rate of additional disease was statistically significantly higher in Group 1 (p=0.030). Albumin level (<2.8 g/dL), lymphocyte/monocyte ratio (<1.35), and hemoglobin level (<8.3 g/dL) were found to be significant predictors of complication development. Conclusion: With the application of ERAS protocols, length of postoperative hospital stay, complication rate, and the need for intensive care hospitalization decrease. Preoperative hemoglobin level, albumin level, and lymphocyte/monocyte ratio are the predictors of complication development. Increasing hemoglobin and albumin levels before operation may reduce postoperative complications.
RESUMO
OBJECTIVES: The Nuss technique comprises the placement of an intrathoracic bar behind the sternum. However, besides improving the body posture through the correction of the pectus excavatum (PE), this procedure may cause or worsen thoracic scoliosis as a result of the considerable stress loaded on the chest wall and the thorax. Our goal was to investigate the impact of the Nuss procedure on the thoracic spinal curvature in patients with PE. METHODS: A total of 100 patients with PE who underwent the Nuss procedure were included in the study and evaluated retrospectively. The Haller index (HI), asymmetry index and sternal torsion angle were calculated from thoracic computed tomography images before the operation. To evaluate the scoliosis in the T2-T8 thoracic vertebrae, Cobb angles were calculated on a plain chest X-ray before the Nuss operation and after the removal of the bar. Cobb angles were classified as normal (5°), scoliotic posture (5°-10°) and scoliosis (>10°). All angles before and after the Nuss operation were compared. The patients were followed up for a mean of 41 months. Substernal bars were removed after a mean of 33 months. RESULTS: The mean age of the patients was 19.6 ± 6.7 years. The Cobb angle was statistically significantly increased in all patients (P = 0.01), male patients (P = 0.01) and children (P = 0.046) but not in adults (P = 0.11) and female patients (P = 0.54). The Cobb angle was increased in patients with severe (HI ≥ 3.5) but not in patients with moderate (3.2 < HI < 3.5) or mild (2.0 < HI < 3.2) PE deformity. CONCLUSIONS: The present study shows that the Cobb angle indicates that the severity of thoracic scoliosis increases following the Nuss procedure, particularly in male patients, in patients with mild and moderate sternal torsion angle and in those with a high preoperative HI. This alteration might be due to correctional forces and torque applied by the bar. Patients undergoing the Nuss procedure for the correction of PE should be followed up strictly for timely diagnosis and management of the scoliosis.
