Abstract

Despite significant advance in laparoscopy, upper gastrointestinal (UGI) series is still generally carried out for preoperative localization of gastrectomy. The aim of the study was to compare the accuracy of UGI series and postoperative pathological findings in the diagnosis and localization of gastric cancer. A retrospective review was carried out for 102 patients who underwent gastrectomy between October 2007 and April 2009. Preoperative reports of UGI series were compared with postoperative pathology reports and the accuracy of the preoperative reports was calculated. Two radiographer retrospectively reviewed the analysis of UGI series. postoperative pathology reports of the surgical specimens, were compared with the preoperative reports of the location and extent of the tumor were correct in 81 case("sure", 79.4%) and incorrect in 21 case("failed, 20.6%). In 92 case UGI series revealed intestinal metaplasia (90.2%) at consensus review and these results demonstrate the limitation of the UGI series in the diagnosis of type IIb gastric cancer with size less than 1.0cm and the poor detection of gastric cancer is that the overlying mucous membrane often appears to be normal in these patients. In conclusion, UGI series is accurate the detection of the tumor localization and diagnosis of intestinal metaplasia. However, for the overcome with the limitation of UGI series should be used accurate technique for the region of the stomach. To achieve this goal, it is necessary to determine the changes of the mucus membrane of the stomach and UGI series is gaining acceptance as a standard method for preoperative gastric cancer screening.
