The transhepatic route for the placement of a duodenojejunal stent: application in a postoperative closed loop obstruction of the duodenum.

A patient who had undergone gastric resection for carcinoma, had closed loop obstruction of the duodenum due to neoplasia at the duodenojejunal junction. The obstruction was relieved successfully by transhepatic placement of a duodenojejunal stent. We were compelled to use the transhepatic route because a Roux-Y reconstruction had been performed. Transhepatic placement may be the only chance of palliation in a small subset of patients with malignant intestinal obstruction.

Preoperative CT staging of colon carcinoma (excluding the recto-sigmoid region).

Twenty-eight patients with colon carcinoma (excluding the recto-sigmoid region) underwent preoperative staging with computed tomography (CT). The CT had a sensitivity and a specificity of 60 and 67% for detection of extramural invasion, 75% sensitivity and specificity for lymph node metastases and a sensitivity of 87% and specificity of 95% for liver metastases. Compared with the modified Dukes classification, CT correctly staged 50% of the patients with Dukes A lesions; 40% with Dukes B; 75% with Dukes C and 85% with Dukes D lesions. The data presented in this study showed that CT has limitations in the sensitivity and accuracy of staging local colonic carcinoma. However, we recommend its use for patients who are clinically suspected of having extensive disease.

CT in lobar atrophy of the liver caused by alveolar echinococcosis.

We reviewed the CT findings of 13 patients with histologically proved alveolar echinococcosis of the liver. Seven of these patients had hilar involvement, which caused dilatation of intrahepatic bile ducts and invasion of the portal vein or portal branches. In two of these patients we found marked atrophy of the right lobe and in one patient marked atrophy of the left lobe in addition to various CT findings previously reported for alveolar echinococcosis of the liver. The occurrence of lobar atrophy of the liver caused by alveolar echinococcosis has not been previously reported. We concluded that, when a mass lesion with hilar infiltration causing lobar atrophy is found in endemic areas, alveolar echinococcosis should be considered in the differential diagnosis in addition to malignant neoplasms.
