Blunt esophageal injury in the setting of multitrauma: A case report.

Blunt esophageal injury is an unusual organ injury that has unclear clinical symptoms due to the overlap of thoracoabdominal trauma in the setting of multiple traumas. The treatment options vary depending on the patient's clinical symptoms, the extent of esophageal damage, and the time from the onset of damage to diagnosis. This article presents a case of a young male patient receiving emergency treatment after a traffic accident. Esophageal perforation was diagnosed through chest computed tomography with contrast injection and oral contrast. The article focuses on imaging characteristics and suggestive signs of blunt esophageal injury in the setting of multitrauma.

Lung Volume Reduction Surgery in Patients with Heterogenous Emphysema: Selecting Perspective.

BACKGROUND: Lung volume reduction surgery (LVRS) was introduced to alleviate clinical conditions in selected patients with heterogenous emphysema. Clarifying the most suitable patients for LVRS remained unclear. AIM: This study was undertaken to specifically analyze the preoperative factor affecting to LVRS. METHODS: The prospective study was conducted at 103 Military Hospital between July 2014 and April 2016. Severe heterogenous emphysema patients were selected to participate in the study. The information, spirometry, and body plethysmographic pulmonary function tests in 31 patients who underwent LVRS were compared with postoperative outcomes (changing in FEV1 and CAT scale). RESULTS: Of the 31 patients, there was statistically significant difference in the outcome of functional capacity, lung function between two groups (FEV1 ≤ 50% and > 50%) (∆FEV1: 22.46 vs 18.32%; p = 0.042. ∆ CAT: 6.85 vs 5.07; p = 0.048). Changes of the FEV1 and CAT scale were no statistically significant differences in three groups residual volume. Patients with total lung capacity < 140% had more improved than others (∆FEV1: 23.81 vs 15.1%; p = 0.031). CONCLUSION: Preoperative spirometry and body plethysmographic pulmonary function tests were useful measures to selected severe heterogenous emphysema patients for LVRS. Patients with FEV1 ≤ 50%, TLC in the range of 100-140% should be selected.
