Endoscopic "salvage" cytology in neoplasms metastatic to the upper gastrointestional tract

Abstract

Endoscopic "salvage" cytology was the only successful nonoperative diagnostic method in two patients with malignancy metastatic to the upper gastrointestinal tract. Smears and cell blocks of centrifuged material aspirated from the endoscope channel provided diagnoses of malignancies when other diagnostic techniques had been nonproductive. The results in these cases support the general utility of this technique and indicate its successful application in this specific clinical setting.
