Meckel's diverticulum: Investigation of 600 patients in Japanese literature

A total of 600 cases, comprising 4 of our cases and 596 others in Japan, was analyzed, and the diagnosis of Meckels diverticulum was made in only 34 of them. The rate of diagnosis was 5.7 per cent, which is very low. The most common complication of this disease was intestinal obstruction, the second most common was intussusception, the third was inflammation, and the fourth was rectal bleeding. Ectopic tissue, present in ninety-three patients, consisted of ectopic gastric mucosa in fifty-eight. 99mTc-P scanning was performed on fifteen patients. In twelve of them ectopic gastric mucosa was observed. However, it was not found in three, all of whom had false-positive scans.

A case of mesenteric cyst diagnosed by ultrasound examination and a review of Japanese literatures.

Mesenteric cyst is relatively rare, and its diagnosis is difficult. We carried out an ultrasound examination on a 6-year-old boy who showed intestinal obstruction. This examination revealed an abdominal mass, and he was diagnosed as mesenteric cyst. Later it was confirmed by operation. The histopathological examination revealed that it was a lymphangioma. A review was also carried out on 288 cases of mesenteric cyst in Japan.

Observation of cystic dilatation of the common bile duct by ultrasonography

We have studied a patient with congenital cystic dilatation of the common bile duct who had undergone ultrasonography five times in 6 mo before operation. Ultrasonography revealed that the duct was distended with inflammation, and was deflated when inflammation was not present.

Occlusion of the deep cerebral veins

There are very few reports on occlusion of the deep cerebral veins in the adult, and none where cerebroangiography was used. We report here a case of occlusion in the Galen and straight sinuses.
