[Vascular complications in intestinal obstructions. The role of computed tomography].

INTRODUCTION: We investigated CT capabilities in showing vascular complications (ischemia, infarction) secondary to intestinal obstruction. SUBJECTS AND METHODS: 32 patients with small bowel obstruction, subdivided in two groups, were examined with CT. The first group consisted of 12 patients with small bowel obstruction complicated by ischemic injury. It was due to loop strangulation in 10 cases and loop distension secondary to colon carcinoma in 2 cases. At surgery the loop strangulation was caused by adhesions in 9 cases and by jejunal hernia in 1 case. Vascular complications were segmentary small bowel infarction in 7 cases, colonic infarction in 2 cases and ischemia, which was resolved after loop debridement, in 3 cases. The second group consisted of 20 patients with intestinal occlusion due to adhesions complicated by a closed loop in 4 cases. All patients were examined with(out) i.v. contrast agent administration. Filling of the intestinal loops by oral contrast agent was never performed. RESULTS: CT identified the vascular injury secondary to intestinal obstruction in 11/12 patients (91%). In one case it was not possible to diagnose mild ischemia, which was found of surgery. CT findings were: loops distention in all the cases; wall thickening in 11 cases with intramural gas in 8 cases and slight contrast enhancement in 1 case; ascites in 2 cases; mesenteric edema in 9 cases; gas at the mesenteric root in 1 case. In the control group, small bowel obstruction was diagnosed with CT in all cases based on the presence of distended loops up to the occlusion site. Parietal alterations above the lesion were never found. CONCLUSION: CT is a sensitive tool for diagnosing small bowel obstruction and for assessing the site and cause of obstruction. CT plays a pivotal diagnostic role in vascular complications, giving very important indications for a correct treatment.

[Intestinal cystic pneumatosis and gastric banding. Etiopathogenic considerations on a clinical case].

The authors describe a case of intestinal cystic pneumatosis in a patient submitted to gastric banding and then proceed with a critical review of the literature on the subject, examining the state of the art with regard to the pathogenetic hypotheses and the clinical manifestations of the disease and outlining the advantages of the instrumental investigations employed. On the basis of clinical considerations, an integrated pathogenetic hypothesis is advanced which takes account of the various indications expressed in the literature. In particular, recurrent vomiting is believed to bring about epithelial microlesions which, in the presence of severe respiratory impairment, the execution of endoscopic examinations and a mainly carbohydrate-based diet, are thought to cause onset of cystic pneumatosis.

[Treatment and results in necrotizing enterocolitis in infancy (author's transl)].

29 children aged between 1 day and 22 months were treated for enteritis with complications. 2 children were cured conservatively. In 27 cases surgery was needed; of these 13 children survived. In 19 patients bacteria were found in the stools. Operation was indicated when there was diffuse peritonitis or when perforation could be shown radiologically. In cases of intestinal perforation the following technique was used in the last few years: 1. resection of the segment involved and ileoor colostomy. 2. Anastomosis and closure of colostomy 4--6 weeks later. Among 29 children with necrotizing enterocolitis there were 12 who also had malformations of the heart and lungs. This made worse a prognosis which was bad anyway.

Pneumatosis coli and multi-slice helical CT virtual colonoscopy.

Helical CT colography is improved by multislicing due to thinner slices. The case reported shows the potential of multislice HCT colography to demonstrate gas-filled cysts on axial images as well as on CT endoscopy, and consequently the extent of the disease exceeding the sigmoid, as was diagnosed by conventional coloscopy.

[Intestinal pneumatosis. Right colon cystic form with linear aspect on scan].

INTRODUCTION: Digestive pneumatosis corresponds to the presence of air in a wall of digestive tract. It is common to oppose primary cystic-type pneumatosis, involving the left colon, with linear-type pneumatosis that may affect the whole of the digestive tract. OBSERVATION: In a 41 year-old man presenting with Sharp's syndrome, abdominal pain occurred revealing an isolated right colon pneumatosis. Although abdominal tomodensitometry showed a strictly linear pneumatosis, colposcopy revealed voluminous cysts. CONCLUSION: With this case report, the limits of tomodensitometry in distinguishing linear from cystic forms are apparent. The importance of avoiding surgery is underlined. Our patient presented with a pneumo-peritonitis only requiring medical treatment since this disease generally regresses spontaneously.

[An unusual cause of an "intramural" gas collection in the right colon (author's transl)].

A case of subserous gas collection in the right colon following surgical repair of an iatrogenic uterus perforation is presented. The patient showed an ileus-like roentgen symptomatology when ischemic necrosis of the bowel was suspected. Laparatomy demonstrated the remainder of the gas collection in the area of the right pelvis extending retroperitoneally towards the right colon, thus presenting intramural pneumatosis. Therefore the differential diagnosis of intramural gas collection as a sign of ischemic bowel necrosis has to include the harmless subserous pneumatosis following abdominal trauma (especially iatrogenic uterus perforation).
