[Malignant triton tumor of the posterior mediastinum treated by thoracoscopic approach. Apropos of a case]. / Tumeur maligne de Triton du médiastin postérieur abordée par thoracoscopie. A propos d'un cas.

A tumour of the posterior mediastinum was removed via thoracoscopy. The histology report was a triton tumour. This is a rare (less than 80 cases reported in the literature) malignant tumour of the nervous system: malignant schwannoma with rhabdomyoblastic differentiation. The characteristics of this rare tumour and the consequences of videoassisted surgery in this specific case are discussed: a second access is required to widen the thoracotomy and complementary radiotherapy is needed.

[Divided pancreas. General review apropos of 6 cases]. / Le pancréas divisum. Revue générale à partir de six observations.

The aim of this work is to perform a general review of pancreas divisum. Six cases are reported. A clinical and therapeutic study is made, successively studying the circumstances of discovery, the morphological and functional studies, and the therapeutic methods. A discussion underlines the learnings and contradictions of the literature about this issue.

[Gunshot wounds of the ureter]. / Les plaies par balle de l'uretère.

Lesions of the ureter caused by penetrating wounds of the abdomen rare a are complication of abdominal gunshot wounds, of which the reported incidence is 2 to 17%. The preoperative diagnosis is difficult and unrecognized initially in every third case. There are no early clinical signs of ureteral lesions. There is often no hematuria. Only IVP can make the preoperative diagnosis possible. As a matter of fact, the diagnosis will often be established by the surgical exploration made during the laparotomy required by the extent of the associated lesions. The ureteral blast contusion is an important cause of secondary necrosis with fistula. The treatment is mainly based on ureteroureterostomy after debridement. The transanasmotic drainage of urine is controversial. Mortality results from associated abdominal lesions and morbidity consists in a risk of secondary nephrectomy.
