ABSTRACT
BACKGROUND:
A few reports suggest that the emergence of double balloon endoscopy (DBE) has likely changed the clinical picture of small bowel tumors (SBTs).AIM:
To further clarify the characteristics of SBTs detected by DBE.METHODS:
A retrospective chart review was conducted in 227 patients who had undergone DBE.RESULTS:
The SBT group contained more symptomatic patients than the non-SBT group (90% vs. 49%, P<0.0005) with a significantly higher rate of gastrointestinal symptoms at presentation (72% vs. 33%, P<0.005). Twenty patients (8.8%) were eventually diagnosed with SBT, and their indications for DBE were obscure gastrointestinal bleeding (n=5), abdominal pain (n=5), abdominal fullness (n=5), vomiting (n=2), and diarrhea (n=1). Tumors were located in the jejunum in 14 patients (70%) and in the ileum in 6 (30%). A final histological diagnosis was assigned to all 20 patients primary adenocarcinoma (n=8, 40%), malignant lymphoma (n=5, 25%), metastatic cancer (n=4, 20%), gastrointestinal stromal tumor (n=1, 5%), carcinoid tumor (n=1, 5%) and inflammatory fibroid polyp (n=1, 5%). Stenosis or ulceration were the most frequently observed endoscopic findings (n=13, 65%). All primary adenocarcinomas and three of four (75%) metastatic cancers showed stenosis or ulceration. Three of five (60%) malignant lymphomas showed multiple lymphomatous polyps. All patients but one underwent surgical resection or chemotherapy or both.CONCLUSION:
DBE is a safe and useful procedure that enables a precise diagnosis of SBTs.
