Article Synopsis
- * A case report describes a 65-year-old man with back pain, weight loss, and abnormal tumor markers, where imaging failed to identify a primary liver tumor, leading to a diagnosis post-mortem revealing multiple diffuse nodules of ICC.
- * This situation underlines the diagnostic difficulties of atypical ICC presentations and stresses the need for thorough evaluations in patients with unexplained symptoms related to liver issues.
Article Synopsis
- This report discusses an unusual case of Erdheim-Chester disease (ECD), highlighting its unique symptoms and challenges in diagnosis.
- The patient presented with significant organ involvement, particularly an uncommon pancreatic enlargement not usually linked to ECD.
- Advanced techniques like contrast-enhanced harmonic endoscopic ultrasonography (CEH-EUS) and EUS-fine needle aspiration (EUS-FNA) were shown to be effective in identifying and characterizing ECD lesions, marking the first documentation of pancreatic lesions in ECD patients assessed with CEH-EUS.

A 70-year-old woman presented to our hospital with jaundice. Abdominal ultrasonography showed biliary duct dilatation. Blood tests revealed elevated total bilirubin and hepatobiliary enzyme levels.

Although fluoroscopy is used to confirm the position of endoscope at DBE, the endoscopist does not have the knowledge with regard to the radiation exposure dose. In this study, we evaluated the absorbed dose during DBE in patients with suspected or established small bowel diseases.

Endoscopic Ultrasonography performed during Double Balloon Enteroscopy, appeared a promising technique although it has not been fully evaluated. The aim was to determine the effectiveness of this technique for characterization and management of sub mucosal tumours in a large cohort of patients.

- Double-balloon endoscopy (DBE) is an effective technique for retrieving foreign bodies from the small intestine, with a success rate of 86.3% based on 22 cases studied.
- The foreign bodies removed included various items such as capsule endoscopes, artificial teeth, medical tubes, and even worms, with no reported complications during the retrieval process.
- The choice of the DBE approach—oral or anal—and the use of appropriate retrieval devices, like snare forceps, are crucial for successful procedures, especially in cases involving small intestine stenosis.
Background/aims: We classified intestinal lymphangiectasia (IL) into two categories, the white and non-white villi types, and evaluated their clinical characteristics and therapeutic responses.
Methods: Of the 988 patients who underwent double-balloon enteroscopy, 14 consecutive patients (7 men and 7 women, median age at onset 34 years) were enrolled with immunohistochemically confirmed IL with protein-losing enteropathy.
Results: Enteroscopically the white villi type (n = 8) showed white plaques and white-tipped villi were scattered in the small bowel, while non-white villi type (n = 6) showed that apparently normal but under more detailed observation, low and round villi with a normal color were diffused.
To our knowledge, this is the first report of Cowden syndrome complicated by a gastrointestinal stromal tumor (GIST) of the small bowel. A 42-year-old female patient was found to have an abdominal mass that was diagnosed as the cause of anemia and was surgically extracted. The surgical specimen was found to be a GIST.
