Abstract:Objective To explore the factors affecting endoscopic detection rate of heterotopic gastric mucosa in the esophagus (HGME), improve the endoscopic detection rate of HGME.Methods Retrospective analysis of 19 948 patients underwent gastroscopy from January to December 2018 was made. Record age and gender of the patients, gastroscopy mode, gastroscopy pattern, gastroscopy doctor level, etc. Analyse the factors affecting the endoscopic detection rate of HGME.Results 282 cases were found HGME, the overall detection rate is 1.41%. The number of HGME cases found in different groups is as follows: 226 cases of painless gastroscopy group (1.53%), and 56 cases of general gastroscopy group (1.07%); 89 cases in NBI group (3.06%) and 193 cases of ordinary white light group (1.13%); 37 cases in resident and low seniority attending physician group (0.89%), 93 cases in senior attending physician (1.48%), 152 cases in senior professional physician group (1.59%). Accord to statistical analysis, gastroscopy mode, gastroscopy pattern, gastroscopy doctor leve have an impact on the endoscopic detection rate of HGME (P < 0.05), the age and gender of patient have no significant impact on the endoscopic detection rate of HGME.Conclusion The endoscopic detection rate of HGME is related to gastroscopy mode, gastroscopy pattern and doctor experience, painless gastroscopy, NBI mode and the experience accumulation of endoscopists can significantly improve the detection rate of HGME.
