Value of Longiludinal Axis Endoscopic Ultrasonography in the Diagnosis of Advanced Gastric Carcinoma

Objective 　To evaluate the value of longiludinal axis endoscopic ult rasonography (LAEUS) in the diagnosis of advanced gast ric carcinoma. Methods 　Twenty-nine consecutive patient s with advanced gastric carcinoma were underwent endoscopy with biopsy for pathology, LAEUS and LAEUS-guided puncture aspiratian for cell pathology, respectively. The result s were compared with those of surgical naked-eye inspections and LAEUS plus LAEUS-guided biopcy. Results 　Final diagnosis of gastric cancer made by endoscopy accounted for 100 %、86. 4 %、80 % and 0 in the patients with Borrmann I, II, III, and IV types of gastric carcinoma, respectively, whereas final diagnosis rate of gastric cancer made by LAE-US plus LAEUS-guided biopcy was 100 %. The diagnosis rate of TNM stages of gastric cancer made by LAEUS plus LAEUS-guided biopcy was 83. 75 % according to the pathological finding of surgical sample. Conclusion 　LAEUS is superior than endoscopy in diagnosis of advanced gastric carcinoma, especially in Borrmann Ⅳof advanced gastric carcinoma.
