Abstract

Background/Aims
There is no guideline about the management of gastric SMT in Korea. The aim of this study was to survey how 2∼3 cm sized gastric SMTs suspicious of gastrointestinal stromal tumor (GIST) are managed by Korean physicians. Methods: The questionnaire was sent to 570 gastroenterologists via e-mail. It was composed of multiple-choice questions on the diagnosis and management for two 2.5 cm sized gastric SMT cases (one with ulceration and one without ulceration). Results: A total of 50 gastroenterologists replied (response rate, 8.8%). For 2.5 cm sized SMT with intact overlying mucosa, only 20% of respondents answered to take biopsies. The preferred second test was endosonography (88%). For 2.5 cm sized SMT with central ulceration, most respondents answered to obtain biopsies (98%). The preferred second test was also endosonography (78%). When gastric SMTs were believed as benign, most respondents preferred resection for a SMT with ulceration (90%). For a gastric SMT without ulceration, respondents equally chose resection (46%) and follow-up (44%). When follow-up was chosen instead of resection, the preferred interval was 6 months. Conclusions: The clinical practice of 2∼3 cm sized gastric SMT was various especially for small gastric SMT with intact overlying mucosa.
