Background
Gastric intestinal metaplasia (GIM) is an accepted pathologic precursor to gastric adenocarcinoma (GAC). While surveillance of GIM in Europe and Asia is common, only limited recommendations related to endoscopic surveillance of GIM exist in the United States.
Aim
To understand the clinical practice patterns of US gastroenterologists in the management and endoscopic surveillance of GIM.
Methods
A 23 item survey was developed to explore endoscopists’ opinions regarding the surveillance of GIM and knowledge of current guidelines. Eight clinical vignettes were developed to address specific clinical scenarios where endoscopic surveillance of GIM might be considered.
Results
There were 227 respondents, with 60 % working primarily in the private sector and 40 % in academic medicine. While 68 % of the respondents refer to major society guidelines for guidance in patient management, almost 78 % of endoscopist responders believe that there are no specific US guidelines pertaining to surveillance of GIM. Only two-thirds of respondents believe that based on current data, patients at increased risk of GAC should be a part of an endoscopic surveillance program, while 15 % believe all patients with GIM should receive endoscopic surveillance. Respondents use a wide range of biopsy techniques and surveillance intervals for patients with GIM, with no consistent pattern of practice identified.
Conclusions
There is variability in the knowledge and practice patterns of US endoscopists related to surveillance of gastric intestinal metaplasia. In the absence of detailed US GI society guidelines, many endoscopists perform surveillance endoscopy on patients with GIM using variable biopsy techniques and surveillance intervals.
