Background/Aims The diagnostic efficacy of current tissue sampling techniques for gastric subepithelial tumors (SETs) is limited. Better tissue sampling techniques are needed to improve pathological diagnosis. The aim of this study was to evaluate the safety and efficacy of a new technique, mucosal incision and forceps biopsy, for reliable tissue sampling of gastric SETs. Methods This study enrolled 12 consecutive patients who underwent mucosal incision and forceps biopsy of gastric SETs between November 2011 and September 2014 at Gangneung Asan Hospital. The medical records of patients were reviewed retrospectively. The safety and diagnostic yield of this method were evaluated. Results By performing mucosal incision and forceps biopsy, we were able to provide a definitive histological diagnosis for 11 out of 12 cases. The pathological diagnoses were leiomyoma (3/11), gastrointestinal stromal tumor (GIST; 2/11), lipoma (2/11), schwannoma (1/11), and ectopic pancreas (3/11). In cases of leiomyoma (n=3) and GIST (n=2), tissue samples were of sufficient size to allow immunohistochemical staining. In addition, the mitotic index was evaluated in two cases of GIST. There were no procedure-related complications. Conclusions Mucosal incision and forceps biopsy can be used as one of several methods to obtain adequate tissue samples from gastric SETs.

Endometriosis is a benign gynecologic disease, characterized by the presence and growth of functional endometrial-like tissue outside uterus. This ectopic endometrial tissue is most commonly found in the peritoneum, ovaries and uterosacral ligaments, but extremely rarely there is involvement of the appendix or cecum. Here we report a case of cecal endometriosis presenting as a subepithelial tumor diagnosed by surgical excision. (Korean J Gastroenterol 2016;68:214-217)

Background: We aimed to study the importance of diabetes education by investigating diabetes education rate and the associations between the presence/absence of diabetes education and the clinical outcomes of diabetic patients in Korea. Methods: In the Fifth Korea National Health and Nutrition Examination survey (KNHANES V), a cross-sectional national survey during 2010 and 2012, 1498 subjects aged over 30 years and older were diagnosed with diabetes by doctors. The subjects were analyzed by a complex samples model. Results: Only 20.3% of diabetes patients received diabetes education, and this was not significantly different between age groups. Education was delivered in hospitals/clinics, public health centers, and public lectures (15.7%, 3.0% and 1.4%, respectively). After adjusting for age, sex, and duration of diabetes, the factors independently associated with the presence of diabetes education were higher education level, frequent walking habit, and parameters regarding the presence of dyslipidemia, insulin treatment, and non-pharmacologic treatment. Among continuous variables, only the duration of diabetes was associated with diabetes education status; metabolic parameters were not associated with diabetes education status. Conclusion: Diabetes is a chronic disease and education on diabetes is very important. The education rate was low and quality of the education is doubtful. An effort to raise the rate of diabetes education and further study to raise the quality of diabetes training are necessary. [ABSTRACT FROM AUTHOR]
