[Idiopathic spontaneous hemoperitoneum.]. / Hemoperitoneo espontáneo idiopático.

UNLABELLED: Intraperitoneal bleeding is common in patients with abdominal trauma or in those with benign gynecologic diseases, but it is very rare to occur spontaneously. The purpose of this communication is to report a female patient with idiopathic spontaneous hemoperitoneum (ISH). CASE PRESENTATION: A 28-year-old patient was admitted with 12-hour acute abdominal pain. Laboratory tests upon admission showed: Hb 9.0 g/dL, WBC 8.9 x 109/dL and negative immunologic pregnancy test. The ultrasound showed free intraperitoneal fluid. She underwent exploratory laparoscopy with findings of massive hemoperitoneum, which was resolved and, after a thorough exploration of the abdominal cavity, no evidence of the bleeding site was found. She was closely followed-up for 2 years without any recurrence or complications related to the ISH. An extensive review of the literature was performed. We conclude that ISH is a rare entity that usually presents as a surgical emergency and whose diagnosis is made in the absence of predisposing factors and excluding lesions in the abdominal blood vessels and organs. It warrants immediate intervention, which is crucial for patient survival.

[Gastrointestinal neurofibromatosis. A rare cause of abdominal surgery]. / Neurofibromatosis gastrointestinal. Una causa poco frecuente de cirugía abdominal.

OBJECTIVE: Report two cases of gastrointestinal neurofibromatosis that required surgical intervention for their resolution. BACKGROUND: Neurofibromatosis is a congenital disease which is classified in two types. In neurofibromatosis type 1 or Von Recklinghausen's disease the patients have some classical manifestations as cafe au lait pigmentation, bony abnormalities and neurofibromas of both peripheral and central nerves. In up to 25% of the patients with neurofibromatosis 1, the gastrointestinal tract is involved. The most affected organs are the stomach and the jejunum. The symptoms of the patients with gastrointestinal neurofibromatosis are related to gastrointestinal bleeding or obstruction. METHOD: Two patients with gastrointestinal neurofibromatosis that required surgical intervention for the resolution of their manifestations. RESULTS: Two cases of gastrointestinal neurofibromatosis, one of them had as her main clinical feature gastrointestinal bleeding, and the other patient intestinal obstruction. They were submitted to exploratory laparotomy finding gastrointestinal neurofibromatosis in both as the cause of their symptomatology. CONCLUSIONS: The management of gastrointestinal neurofibromatosis could need surgical intervention, and when this is done the postoperative evolution is satisfactory.
