The diagnosis and correction of a rare case of traumatic transpericardial diaphragmatic hernia is presented with spontaneous intraoperative reduction by the verification of the lesions of the left lateral wall of the pericardium, diaphragmatic pericardium, and the central tendon, with intact left hemidiaphragm. Only one such case has been published in the last thirty years.

Objective: To compare the resistance of manual suture with that of mechanical suture immediately after the suture of the left bronchial stump of dogs submitted to pneumonectomy. Methods: A total of 15 mixed-breed dogs of both genders, each weighing between 8 and 23 kg, were randomly divided into 2 groups. In group I (n = 7), the bronchial stump was sutured manually (the Sweet method) and, in group II (n = 8), it was stapled. Immediately after the closure of the bronchial stump, the intratracheal pressure was progressively increased in a controlled manner. Results: The mean rupture pressure of the bronchial stump suture line was 33.71 mmHg in group I and 89.87 mmHg in group II (p < 0.01). Conclusion: These data allowed us to conclude that mechanical suture of the bronchial stump, submitted to pressure immediately after closure, is more resistant than is manual suture in dogs submitted to pneumonectomy.

Lipomas are benign neoplasms composed primarily of adipose tissue and may be located in various parts of the body. The case reported is that of a patient who sought medical assistance complaining of recurring pneumonia. After diagnostic procedures, including chest X-ray and computed tomography scan of the chest, endobronchial lesion with fat density was suspected. The diagnostic hypothesis was endobronchial lipoma. This hypothesis was confirmed after surgical intervention. The aim of this study was to report this case of endobronchial lipoma and to review the available literature on the subject.
