—This manikin illustrates a No. 18 Levin tube situated just distal to an infiltrative squamous-cell carcinoma preparatory to irrigation.
—A No. 18 Levin tube in position near an ulcer of undetermined etiology of the lesser curvature of the stomach.
—By means of a double-lumen Diamond tube exfoliated malignant cells may be recovered from carcinomas of the pancreas, common bile duct or gallbladder.
—Malignant cells can be recovered from carcinomas of the cecum and splenic flexure by irrigation through a No. 12 Ewald tube inserted to the rectosigmoid.
In recent years exfoliative cytology has become increasingly useful as a method of diagnosing cancer of the gastrointestinal tract. The cytologic procedures, as illustrated on the following pages, demonstrate the relative simplicity of the techniques. The methods of obtaining malignant cells from the esophagus, stomach, duodenum, and colon are satisfactorily performed by trained cytotechnicians.
