title: Conventional video-gastroscopes for the recognition of early gastric cancers.
abstract: OBJECTIVE
  To determine the role of conventional video-gastroscopes for detection of early gastric cancers (EGC).
  
  
  METHODS
  All conventional upper gastrointestinal endoscopy (UGE) reports (12000 UGE reports) and pathology reports of all UGEs, between January 2003-December 2008, were evaluated retrospectively.
  
  
  RESULTS
  The endoscopist suspected for EGC in 163 patients. In pathological examination, EGC was confirmed only in 35 patients. In reports of another 8 patients, the endoscopist did not suspect for EGC, but in pathological examination EGC was detected. Totally EGC was defined in 43 patients [28 male, 15 female, median age; 64 years (range 29-96 years)]. Of these 43 patients, 11 were inoperable, and 32 were operated. Among those operated, finally 17 patients were diagnosed with real EGC (10% of suspected cases). The frequency of H. pylori and atrophy were 29% and 41%, respectively. Incomplete intestinal metaplasia was mostly with submucosal invasion (41%). The most common location was the corpus and the patients with mucosal EGC commonly underwent subtotal gastrectomy. The majority (82%) of the cancers were intestinal-type according to Lauren histological classification. No relation was detected between invasion-depth and lymph node metastasis and number. The sensitivity, specificity, positive and negative predictive values were found as 84%, 99%, 26% and 99% respectively.
  
  
  CONCLUSIONS
  Conventional endoscopes have excellent specificity and negative predictive value and moderate sensitivity for early recognition of EGC. Most of early detected cancers were out of endoscopic treatment range. One-tenth of suspicious lesions were early gastric cancer, the corpus was frequent site and half of incomplete intestinal metaplasia cases were along with it.
