Traumatic tricuspid valve regurgitation: A challenging case report.

Traumatic tricuspid regurgitation (TR) is a rare cause of acute right ventricular dysfunction. The surgical technique could be complex and the reparative gesture has a lower success rate when compared with functional TR. We present the case of a 26-year-old male patient with traumatic TR who underwent tricuspid valve repair, with an initial satisfactory result. Later, the onset of acute severe residual TR was observed and the valve needed to be replaced. Surgery is the mainstay of treatment for traumatic TR, either in the form of repair or replacement. It requires an early diagnosis and concomitant treatment of injuries.

A stuck colonoscope in the chest cavity: An uncommon complication.

Colonoscopy is generally considered a safe procedure, with a low rate of complications. Although rare, the migration of the colonoscope may represent life-threatening events, requiring emergency treatment. We, herein, describe the case of an elective colonoscopy complicated by an irretrievable colonoscope that migrated, through a previous traumatic diaphragmatic hernia, in the chest cavity. This hernia was likely a chronic complication of a previous abdominal trauma. Several attempts to retrieve the scope were unsuccessful. After further investigations and collegial discussion, a left thoracotomy was performed, with the aim to retrieve the colonoscope and to reduce the hernia.
