[Two cases of small bowel ischemia due to unusual cause].

The authors report 2 cases of small bowel ischemia due to unusual cause. In both cases, vasculopathy was the cause of ischemia, but with a different etiology. In the first case, a mesenteric inflammatory veno-occlusive disease, with striking features of extensive phlebitis and venulitis affecting the veins of the small intestine and mesentery, without arterial involvement of this district was observed and histological examination showed inflammatory lymphocytic infiltrates and myointimal hyperplasia of the veins.

[Intestinal occlusion caused by persistent omphalomesenteric duct and Meckel's diverticulum: report of 2 cases].

Two rare cases of mechanical intestinal obstruction due to an omphalomesenteric duct remnant and/or to a Meckel's diverticulum, respectively, are reported. The first case was a 20-year-old man and the second an 87-year-old woman. In contrast with various reports in the literature, our experience demonstrates that this kind of obstruction may also affect elderly female patients in western countries.

[Diverticulosis of the colon: complications of surgical interest].

Diverticular disease is prevalently only of medical interest. Repeated episodes of diverticulitis, particularly in younger patients, and serious complications such as perforation, stenosis, fistula and haemorrhage demand surgical treatment. The timing and type of surgical operation are conditioned by the pathological picture and by the patient's general condition and age.

[Sigmoid occlusion due to endometriosis. A case report].

The Authors report a case of sigmoid obstruction due to endometriosis and review the literature about. Unusual localisation and difficult preoperative differential diagnosis with IBD and bowel carcinoma are stressed. A 45-years old woman with previous history of oophorectomy was admitted at the hospital with symptomatic bowel obstruction.

[Surgical treatment in acute cholecystitis emergencies].

The aim of the study was to demonstrate the importance of early laparoscopic cholecystectomy for acute cholecystitis, without "conservative" treatment (intravenous fluids and antibiotics for 48-72 hours) to reduce inflammation. Early laparoscopic cholecystectomy reduces bile duct injury and the percentage of conversion to open cholecystectomy. Thirty-five patients with acute cholecystitis were submitted to early laparoscopic cholecystectomy, equally divided according to sex.
