Gastroscopy and pathological features of early gastric cancer

Abstract

Objective To investigate the gastroscopy and pathological features of early gastric cancer diagnosed by gastroscope. Methods Eighty patients with early gastric cancer admitted to Houma People’s Hospital from August 2015 to December 2018 were randomly selected. All patients underwent gastroscopic, and were evaluated microscopically with reference to the clinical diagnosis criteria for gastric cancer and the classification criteria for early gastric cancer classification of the Japanese Endoscopic Society, the lesion tissue for pathological examination was extracted, and referred to the pathological classification criteria for typing. Results The 80 patients with early gastric cancer had abdominal pain above clinical symptoms (71 cases, accounting for 88.75%) as their main manifestation, followed by nausea, vomiting, and upper gastrointestinal bleeding. The type of microscopic classification was high in order from type Ⅱ (32, accounting for 40.00%), type III (27 cases, accounting for 33.75%), type I (21 cases, accounting for 26.25%), the position of the lesion from high to low was the gastric antrum (68 patients, accounting for 85.00%), (52 cases, accounting for 65.00%), gastric angle (41 cases, accounting for 51.5%), and cardiac (29 cases, accounting for 36.25%). Papillary adenocarcinoma was the most common pathological feature of early gastric cancer (31 cases, accounting for 38.75%), followed by highly differentiated tubular adenocarcinoma, moderately differentiated adenocarcinoma, poorly differentiated adenocarcinoma, mucinous adenocarcinoma, and signet ring cell carcinoma. Conclusions The clinical symptoms of early gastric cancer are atypical. It is easier to locate lesions and types under gastroscopy. The pathological results of specimens extracted under gastroscopy can clarify the nature of gastric cancer. Key words: Gastric cancer; Gastroscopy; Papillary adenocarcinoma
