[Difficult digestive hemorrhage: angiodysplasia]. / Emorragie digestive difficili: le angiodisplasie.

The authors report 7 cases of ileal and colonic angiodysplasia observed over a 3 year period (1992-1994). After a review of literature concerning etiology, pathology, diagnosis, and treatment emphasize the use of angiography for preoperatory diagnosis an intraoperatory localization of the lesion when this one is localized in the ileum. After review of usefull therapies, they stress the role of surgery as the most used therapy and only really complete.

[Colonic anastomoses. Methods compared]. / Le anastomosi coliche. Metodiche a confronto.

The authors used Bar-Valtrac for 18 months to perform colic anastomoses. To weigh up the effectiveness of this method they compare manual, Stapler and Bar-Valtrac anastomoses performed in this period. They examined 169 anastomoses in the same number of patients being careful of complications, post-operative canalizing, periods in hospital. It is clear that Bar-Valtrac is a good alternative to the stapler and to manual anastomoses because it is done in a way that doesn't determine anastomotic foreign body reactions and consequently reduces stenotic complications. The limit of this method is the great difficulty in performing low and very low colo-rectal anastomoses. Actually, to perform low and very low anastomoses, the authors prefer to use the Stapler that offers higher probabilities of recovery without complications and higher speed of carrying out.

[Digestive hemorrhage due to an unusual cause: duodenal varices]. / Emorragia digestiva da causa rara: le varici duodenali.

The paper reports a case of digestive hemorrhage due to duodenal varices in a cirrhotic patient. The authors emphasise the extreme rarity and severity of this pathology and, in accordance with the literature, underline the difficulty of selecting the correct approach.

[Double aneurysm of the common hepatic artery and of the right gastric artery]. / Doppio aneurisma dell'epatica comune e della gastrica destra.

An infrequent case of two visceral aneurysms (an hepatic artery aneurysm detected after the rupture of a gastric artery aneurysm) is reported. Clinical features and surgical approach are briefly discussed.
