Esophagography and esophagoscopy. Comparison in the examination of patients with head and neck carcinoma.

We carried out a prospective, double-blind study at three institutions, comparing esophagography with esophagoscopy for the detection of simultaneous cancer of the esophagus in patients with other squamous cell cancers of the head and neck. The goal was to determine whether esophagography and esophagoscopy are necessary for the examination of patients before treatment. One hundred eighty-two patients were studied; both examinations were done in 148 patients.

Roentgenographic features of acute nonobstructive appendicitis: a case report.

We document a case of acute nonobstructive appendicitis and critically evaluate the pertinent literature. Although undoubtedly a rare entity, nonobstructive appendicitis may occur and should be differentiated from a normal appendix by barium enema examination. Mucosal and intramural inflammatory abnormalities are described which permit the diagnosis of nonobstructive appendicitis.

Small-bowel lymphoma and regional enteritis: radiographic similarities.

Lymphoma and regional enteritis may demonstrate strikingly similar patterns in the small bowel. Fifty cases of regional enteritis and small-bowel lymphoma were reviewed. Of these, there were 12 cases of both diseases in which a confident radiographic distinction could not be made.

Growth characteristics of human esophageal epithelial cells in primary explant and serial culture.

Growth characteristics of human esophageal epithelial cells have been determined in primary explant and serial culture. Normal human esophagus was obtained from donor patients in a heart/lung transplantation program; tissue obtained at autopsy (6 to 22 h after death) was not viable. When mucosal specimens (1.
