Abstract: Introduction and Patient Profile: Introduction of deep enteroscopy (capsule endoscopy (CE), balloon-assisted enteroscopy, and spiral enteroscopy) has led to a significant improvement in diagnosis and management of obscure gastrointestinal bleeding (OGIB). Small bowel (SB) lesions are traditionally discovered by CE or double balloon enteroscopy (DBE). Leiomyosarcomas are rare SB tumors and must be diagnosed early to prevent the risk of metastasis and to improve prognosis. A 46-year-old previously healthy woman presented with 3 weeks of abdominal pain and OGIB. Interventions and Outcomes: Patient underwent usual endoscopic modalities in identifying the source of her gastrointestinal bleeding. Computerized tomography scan identified intussusception of the SB; however, conventional endoscopy and CE were negative for etiology of source of bleeding. Ultimately, DBE successfully located the site of gastrointestinal bleeding, confirmed by pathology as a leiomyosarcoma of the SB. Discussion: Conventional endoscopy and CE may miss some lesions, while DBE can navigate altered SB anatomy, take biopsies, and even provide therapy to the lesion. Although double balloon enteroscopies are expensive and require longer sedation than average endoscopic modalities, they may provide another tool for the diagnosis of SB lesions when other modalities are unsuccessful.
