[Successful management of severe unremitting chylothorax after thoraci trauma]. / Trattamento efficace di chilotorace grave e persistente dopo trauma toracico.

Post-traumatic chylothorax needs surgical approach when conservative treatment is not successful to reduce chyle leakage. Thoracic duct ligation requires thoracoscopic or thoracotomic access. The authors report on a surgical thoracotomic approach to a severe and unremitting thoracic duct lesion after IX and X ribs and vertebral fractures.

[Inflammatory colitis: classification and surgical treatment]. / Le coliti infiammatorie. Classificazione e trattamento chirurgico.

The development of clinical and histopathological criteria for the diagnosis of Crohn's disease (CD) and ulcerative colitis (UC), pushed the scientists to identify a new category: the indeterminate colitis (CI). This term is used when definitive diagnosis of UC or CD has not been made by colonoscopy, colonic biopsy or colectomy. The distinction between these forms has major implications including the choice of medical treatment, timing of surgery, prognosis and disease course. The role of surgery in inflammatory bowel disease differs between the three main forms: in CD is primarily to treat complications of the disease process; in UC surgery is curative for intestinal manifestations and nearly eliminates the risk of future malignancy; in IC is actually discussed: the current guidelines identify in surgery the best treatment for fulminate disease, intractability of disease symptoms or failure of medical therapy. Although there is a few number of studies in the literature, selective criteria for the diagnosis and successful treatment must be revisited. The term CI should be used as a pending tray diagnosis, representing diagnostic inadequacy and not as specific nosological entity. Evidence emerging from the studies of serological markers (ASCA and P-ANCA) suggests that a subgroup of patients initially diagnosed as IC maybe identified as a separate group, and so they need a specific treatment for their disease.

Verocytotoxin-producing Escherichia coli EH 0157:H7 colitis.

0157:H7 is a known etiologic agent of hemorrhagic colitis. The clinical and histologic picture of colitis is largely similar to that of ischemic colitis, with areas of submucosal hemorrhage and edema, erosions, and ulcerations. We present a case report and review of the literature. A 52-year-old HIV-positive man, in apparently good immunologic condition, developed severe hemorrhagic colitis characterized by the onset of multiple colonic perforations and an unfavorable outcome. The diagnosis of 0157:H7 colitis should therefore be considered in all patients with indeterminate hematic diarrhea. Further studies are warranted to verify whether HIV infection may play a determinant role in the clinical course of 0157:H7 infection.
