Objective: Bronchial stump dehiscence is still the most feared complication for the thoracic surgeon, with mortality rates ranging from 25% to 75%. This study reports the histologic effect of adult stem cells in the healing process of the bronchial stump after lung resection.
Methods: A left pneumonectomy was performed in 36 Wistar rats. Half of them received previously labeled bone marrow-derived stem cells applied to the bronchial stump. In each group, 7 rats were sacrificed on day 7 and 11 rats were sacrificed on day 21. Macroscopic variables and histopathologic features were analyzed.
Results: On days 7 and 21, there were fewer adhesions in the stem cell group (P = .042 and .031, respectively). Bronchial stump restitutio ad integrum on day 21 was found predominantly in rats from the stem cell group (P = .012). At that time, the same group showed significantly less inflammation in every layer of the stump (P < .050).
Conclusions: Bone marrow-derived stem cells administered topically on a bronchial stump are able to migrate, reach the bronchial wall, and participate in the healing process. This induces fewer adhesions, less inflammatory response, and better regeneration of the tissue.

Objective: The objective of this study was to investigate the utility of preoperative 18F-FDG PET/CT scanning in preoperative evaluation and surgical planning for pulmonary tuberculosis.
Methods: The study involved a retrospective analysis of clinical data and preoperative chest 18F-FDG PET/CT data of 24 patients with pulmonary tuberculosis who underwent pneumonectomy at the Shanghai Public Health Clinical Center between December 2017 and January 2022.
Results: All 24 patients successfully underwent chest 18F-FDG PET/CT imaging, and complete data pertaining to the maximum standardized uptake value, mean standardized uptake value, minimum standardized uptake value, total lesion glycolysis, and metabolic tumor volume were obtained.

A man in his 60s, who had undergone surgery for rectal cancer, liver metastases, and lung metastasis, had a past history of myocardial infarction and ventricular fibrillation with reduced cardiac functions. He was referred to our department because of a pulmonary nodule shadow in the S2 right upper lobe and a bronchial cast shadow along the B2 bronchus. Robot-assisted thoracoscopic right S2 segmentectomy was performed and intraoperative bronchoscopy revealed a polyp-like tumor within B2a.

Bronchopleural fistula (BPF), a common complication of lobectomy, is a pathological communication between the bronchus and the pleural space. The bronchial stump fistula (BSF), which is located on the bronchial stump, is a specific type of BPF. BSF can be directly diagnosed via bronchoscopy.

A male patient (age: 85 -years) with lung cancer underwent basal segmentectomy. Subsequently, he underwent emergency open window thoracotomy for a bronchial stump fistula. The general and nutritional conditions of the patient improved; nevertheless, natural closure of the fistula did not occur.
