Endoscopic Diagnosis and Clinical Analysis of Early Gastric Cancer

Objective To analyze the feature of endoscopic diagnosis and clinical characteristic of early gastric cancer to raise the correct rate of diagnosis.Methods Analyze retrospectively the clinical data of 144 patients from May 2007 to October 2009 with early gastric cancer confirmed by operation and endoscopic resection to summarize the endoscopic feature of the disease.Results 124 patients with early gastric cancer were diagnosed by preoperative gastroscope examination,and 20 patients were diagnosed by ultrasonic endoscope.31.9%(46/144) of the tumors were located in the antrum and 30.6%(44/144) were in the angulus.Type Ⅱ(105/144,72.9%)is predominant,among which 34 cases were type Ⅱa,15 cases type Ⅱb and 56 cases type Ⅱc.Type Ⅲ was found in 24 cases(16.7%) and type I in 15 cases(10.4%).100 patients were diagnosed by one gastroscope examination,and 44 were diagnosed by two or more gastroscope examinations.Conclusion Type Ⅱ is common in patients with earth gastric cancer and the predilection site is in the antrum.The main diagnosis method is gastroscope examination combining multiple punch biopsies.Endoscopic ultrasonography is helpful to the diagnosis and theraphy of early gastric cancer.
