Preoperative assessment of resectability in gastroesophageal carcinoma by linear array endoscopic ultrasonography.

Preoperative endoscopic ultrasonography (EUS) was performed in 51 consecutive patients with biopsy-verified esophageal or gastric cancer, to judge resectability. A comparison between preoperative EUS and surgical (and histologic) findings was possible in 39 patients (76%). In 33 of these 39 patients (85%) EUS made a correct preoperative assessment. In three cases misinterpretation was due to metastasis outside the viewing field of the echoendoscope. Although based on preliminary experience, we are convinced that EUS will help us to select patients who will ultimately benefit from surgery. Further prospective studies are necessary to clarify the possible benefits in terms of costs, effects of palliation in selected patients, and long-term survival.
