[Electronic sectorial ultrasound endoscopy in benign and malignant tumoral pathology of the stomach. Results in 30 patients].
From October 1991 to July 1992, endoscopic ultrasound examination (EUS) was performed preoperatively in 30 patients with gastrointestinal disease with a new forward-view fiber optic gastroscope with a 5 and 7.5 MHz curved-array linear transducer mounted directly behind the lens. Before EUS examination, endoscopy with biopsy had established the diagnosis of gastric disease in 22 cases: 16 adenocarcinoma, 4 lymphoma, 1 carcinoid tumor and 1 gastric metastasis of a chorionic tumor. In the 8 other cases, endoscopic diagnosis with non productive biopsy was gastric ulcer (1 case), submucosal tumor (5 cases), and large fold gastritis (2 cases). EUS established a correct diagnosis in 6 of these 8 cases (2 leiomyoma, 1 lipoma, 1 lymphoma, 2 gastric linitis). Correct preoperative TN staging was accomplished by EUS in 83.3% and correct preoperative staging for N was accomplished by EUS in 90%. This study shows that EUS a curved-array transducer is useful in preoperative TN staging of gastric tumors.
