Radiology of colonic interposition and its associated complications.

A retrospective review of the medical records, pathology reports, and radiographic studies of 81 patients who had undergone colonic interposition was undertaken, with special attention to postoperative complications. Both early (within 30 days postoperatively, 81 patients) and late (later than 30 days postoperatively, 57 patients) complications were reviewed. Early findings included anastomotic narrowing (18 patients), anastomotic leak (13), aspiration (11), and ischemic necrosis of the colon (3). Late findings included aspiration (9 patients), anastomotic strictures (8), gastric stasis (6), redundancy and tortuosity of the colon (5), anastomotic ulcers (4), gastrocolic reflux (3), and gastroesophageal reflux into the residual esophagus (2).

Distension of intestinal tube balloons causing small bowel obstruction.

Intestinal tubes used for the relief of intestinal obstruction can, although rarely, lead to obstruction themselves when the mercury balloon becomes distended with gas or fluid. The mode of distension differs between single and double lumen tubes. Radiographically, there is lack of advancement of the tube tip and persistent small bowel distension. An oval or sausage-shaped lucency is present around the tube tip when the balloon is filled with gas. If the balloon is filled with fluid, oral contrast is necessary to allow its visualization. Percutaneous needle balloon puncture is often necessary to relieve gaseous distension of the balloon of a single lumen intestinal tube, while aspiration of the balloon port is usually successful with the double lumen type. We report on two patients with bowel obstruction from intestinal tubes.

Radiologic manifestations of the syndrome of neurocrest and colonic tumors.

This report describes the radiologic findings in the recently described syndrome of multiple colonic polyps and malignant tumors of neurocrest origin. One patient had multiple endocrine neoplasia syndrome type 11B with malignant medullary thyroid carcinoma, another had malignant pheochromocytoma, and the third had malignant carcinoid tumor. All patients had multiple colonic tubular or tubulovillous adenomas. In 2 patients, there were 8 sessile or pedunculated polyps distributed throughout the colon. In the patient with multiple endocrine neoplasia syndrome type 11B, the colon was carpeted with small polyps, 2-6 mm in size.

Enhancement of pulmonary vasculature in pulmonary consolidation as seen by computed tomography.

Computed tomography of the chest is often useful in evaluating lung consolidation and endobronchial obstruction. Our case demonstrates a consolidated lung associated with endobronchial obstruction and an interesting finding of enhanced pulmonary vasculature contrasted against surrounding pulmonary parenchyma of low density. We believe this represents the computed tomography appearance of drowned lung.

Barrett oesophagus: analysis of 19 cases.

This article reviews our experience with 19 cases of Barrett oesophagus. Radiological findings included hiatus hernia, gastro-oesophageal reflux, strictures and oesophagitis. The strictures were most commonly distal. The recently described lace-like reticular pattern of the mucosa was noted in one case of the 15 who had air-contrast views. It was associated with an adjacent stricture. The low incidence of this radiological finding emphasises that Barrett oesophagus is a histological diagnosis. Six patients had only the non-specific and common radiological findings of reflux with or without hiatus hernia and one patient had a normal examination. These seven cases demonstrate the lack of suggestive radiological findings in some patients.

CT appearance of the inferior mesenteric vein.

The CT appearance of the inferior mesenteric vein (IMV) was studied. It can best be identified by its location behind or to the left of the duodenojejunal flexure. Superiorly, it drains into either the splenic vein, superior mesenteric vein, or the splenoportal junction. Inferiorly, it continues to the left of the fourth stage of the duodenum, lying in the left anterior pararenal space. Occasionally, the left colic vein is seen draining into the IMV. In 14 normal cases the diameter of the IMV, measured behind or to the left of the duodenojejunal flexure, was 3-6 mm with a mean of 3.9 mm and a standard deviation of 0.83 mm. In a case of portal hypertension it measured 9 mm. Thus, the IMV can be used to suggest portal hypertension.

Plain film manifestations of retrocrural disease.

The following plain film findings of retrocrural disease were demonstrated by two patients: a) silhouetting, by a soft-tissue density, of a previously seen inner margin of the crus, b) lateral displacement of the crus, c) lateral deviation of the inferior portion of the paraspinal line, and d) abrupt obliteration of the upper portion of a well defined crus.

Chronic calcified empyema.

Three patients with chronic calcified "fibrothorax" and complicating empyema are reported. The so-called chronic "fibrothorax" may envelop a fluid-filled cavity. Reactivation or reinfection can occur after a very long latent period. When this occurs, it is often associated with either a bronchopleural or a pleurocutaneous fistula. Contrary to often quoted opinion, the calcification a fibrothorax is found on the parietal as well as visceral pleura.

Endoscopic, radiographic, and clinical response to prolonged bowel rest and home parenteral nutrition in Crohn's disease.

Total parenteral nutrition is widely used as a therapeutic measure in patients with severe, active Crohn's disease unresponsive to conventional medical management. We have reviewed our experience with 10 patients with nonfistulous Crohn's disease treated by home parenteral nutrition (HPN) and bowel rest (nothing-by-mouth) assessing the nutritional, radiologic, endoscopic, and clinical responses. After a mean of 4.1 months of treatment, all patients had a marked improvement in nutritional status and resolution of gastrointestinal symptoms; 90% reduced their corticosteroid dose. Eight of nine patients had endoscopic and/or radiographic evidence of mucosal healing. Although 60% of patients were able to avoid surgery and tolerate refeeding, all six patients continue to require steroids to control symptoms. Our study suggests that HPN and bowel rest is a useful therapeutic approach to selected patients with active Crohn's disease, which permits a reduction in corticosteroid dosage and partial healing of mucosal lesions in most. Further studies are required to determine which patients should receive HPN and its optimal duration.
