Background
/Aims: Small bowel malignancies often present a diagnostic challenge due to their relative rarity and nonspecific clinical symptoms. However, technical developments in endoscopic instruments, including video capsule endoscopy (VCE) and enteroscopy, have allowed for the visualization of the entire small bowel. This study aimed to investigate the clinicopathological features of small bowel malignant tumors diagnosed by VCE and double-balloon enteroscopy (DBE) in a single tertiary center.
Methods
We retrospectively analyzed VCE and DBE findings from Korea University Guro Hospital from January 2010 through September 2018.
Results
A total of 510 VCE and 126 DBE examinations were performed in 438 patients. Small bowel malignancies were diagnosed in 28 patients (15 males; mean age, 61.0 years; range, 42 to 81 years). Among them, 8 had lymphoma, 8 had primary adenocarcinoma, 7 had gastrointestinal stromal tumor (GIST) and 5 had metastatic cancer. Abdominal pain and obstructive symptoms were the most common findings in metastatic cancers (4/5, 80%). On the other hand, obscure gastrointestinal bleeding was the most common symptom of GIST (6/7, 85.7%) and adenocarcinoma (3/8, 37.5%).
Conclusions
Approximately 6% of the patients who underwent either VCE or DBE were diagnosed with small bowel malignancy. These findings demonstrated the different clinical characteristics among small bowel malignancies and merit further study.

Education and Training Guidelines for the Board of the Korean Society of Gastrointestinal Endoscopy

Clin Endosc 2017;50(4):345-356.   Published online July 31, 2017

AbstractAbstract PDFPubReaderePub
The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

A Case of Giant Inflammatory Ileal Polyp Removed by Double-Balloon Enteroscopy

AbstractAbstract PDFPubReaderePub

Inflammatory fibroid polyps are rare benign tumors of the GI tract, that commonly present with intestinal obstruction as a result of intussusceptions in the small bowel. A 39-year old man visited our clinic with an asymptomatic polypoid mass in the distal ileum that was identified on abdominal computed tomography for postoperative surveillance after total gastrectomy due to previously diagnosed early gastric cancer. Retrograde double-balloon enteroscopy was performed to diagnose the ileal mass and a complete resection of the polyp was performed using snare for polypectomy without complications. The final histological finding was an ileal inflammatory polyp. Balloon-assisted enteroscopy is a valuable modality to diagnose and treat small bowel lesions in lieu of surgical procedures in selected cases.
