The incidence of small bowel tumors is increasing over time. Until recently, their diagnosis was delayed and it was often reached only at the time of surgery. New diagnostic tools, such as capsule endoscopy, device-assisted enteroscopy, and dedicated small bowel cross-sectional imaging techniques, have been introduced recently in clinical practice. The combination of these tools allows medical practitioners to detect small bowel tumors at an early stage and to reach a definite diagnosis before surgery, thus enabling minimally invasive treatments...

A 77-year-old male with a history of metastatic scalp angiosarcoma presented with intractable gastrointestinal bleeding from a jejunal mass detected on capsule endoscopy. He underwent laparoscopic-assisted resection of the mass. Intraoperatively, an isolated small bowel mass with bulky lymphadenopathy was seen and resected en bloc. Pathology showed a 6.8cm high-grade metastatic angiosarcoma with nodal involvement and negative margins. Angiosarcoma is a sarcoma with a grim prognosis. The incidence is 2% of all soft tissue sarcomas; cutaneous lesions comprise 27% of manifestations and usually appear on head and neck...

GOALS: To compare the efficacy of video capsule endoscopy (VCE) with computed tomography enterography (CTE) in potential small bowel (SB) bleeding, and to identify factors predictive of a high diagnostic yield for CTE. BACKGROUND: In potential SB bleeding, CTE potentially detects some lesions missed by VCE, but few data have determined its clinical utility. STUDY: Consecutive patients with potential SB bleeding were prospectively enrolled...

BACKGROUND: Small bowel neuroendocrine tumors (SB-NETs) are often small, multifocal, difficult to localize preoperatively, and can be overlooked during operative exploration. The optimal work-up and operative approach is unknown. METHODS: Patients who underwent resection of SB-NETs at a single-institution from 2000 to 2014 were included. Primary aim was to describe the diagnostic work-up and compare minimally invasive (MIS) to open resection. RESULTS: Ninety-three patients underwent resection for SB-NETs...

Small bowel melanoma (SBM) is a rare entity, which often evades diagnosis and therefore presents late. Its origin, whether arising primarily or metastatically from an unidentified or regressed primary cutaneous melanoma, remains debatable. In this report, we present a rare case of primary SBM and review the current literature. A 60-year-old man presented with melena and microcytic anemia. A series of investigations including abdominal ultrasonography (US), esophago-gastro-duodenoscopy (EGD) and colonoscopy were normal...

Deep enteroscopy allows for the diagnosis and treatment of small bowel disorders that historically required operative intervention. There are a variety of endoscopic platforms using balloons and rotational overtubes to facilitate small bowel intubation and even allow for total enteroscopy. Obscure gastrointestinal bleeding is the most common indication for deep enteroscopy. By visualizing segments of the small bowel not possible through standard EGD or push enteroscopy, deep enteroscopy has an established high rate of identification and treatment of bleeding sources...

The small bowel is a challenging area for endoscopic evaluation and therapy due to its length and angulated configuration. A small lumen diameter and segmental peristalsis made it a perfect fit for examination by a novel ingestible wireless camera in a capsule. The development of capsule endoscopy changed the diagnosis and management of bleeding lesions, ulcers, and tumors deep in the small bowel, allowing earlier diagnosis with excellent patient acceptance. Device-assisted enteroscopy revolutionized small bowel therapy, particularly management of bleeding, Peutz-Jeghers polyposis, and tumor marking for minimally invasive surgery...

Small bowel capsule endoscopy (CE) was first introduced 15 years ago, and a large amount of literature has since been produced, focused on its indication, diagnostic yields, and safety. Guidelines that have made CE the primary diagnostic tool for small bowel disease have been created. Since its initial use in the small bowel, CE has been used for the esophagus, stomach, and colon. The primary indications for small bowel CE are obscure gastrointestinal bleeding, unexplained iron deficiency anemia, suspected Crohn's disease, small bowel tumors, nonsteroidal anti-inflammatory drug enteropathy, portal hypertensive enteropathy, celiac disease, etc...

Video capsule endoscopy (VCE) has expanded the range of endoscopic examination of the small bowel. The clinical application of VCE is mainly for obscure gastrointestinal bleeding (OGIB) and small bowel tumor is one of the clinically significant diagnoses of VCE, often requiring subsequent invasive interventions. Small bowel tumors are detected with a frequency of around 4% with VCE in indications of OGIB, iron deficiency anemia, unexplained abdominal pain, and others. Protruding mass with bleeding, mucosal disruption, irregular surface, discolored area, and white villi are suggested as the VCE findings of small bowel tumor...

Wireless capsule endoscopy (WCE) has been a revolutionary technique to noninvasively inspect gastrointestinal (GI) tract diseases, especially small bowel tumor. However, it is a tedious task for physicians to examine captured images. To develop a computer-aid diagnosis tool for relieving the huge burden of physicians, the intestinal video data from 89 clinical patients with the indications of potential tumors was analyzed. Out of the 89 patients, 15(16.8%) were diagnosed with small bowel tumor. A novel set of textural features that integrate multi-scale curvelet and fractal technology were proposed to distinguish normal images from tumor images...

Small-bowel neoplasms are the 3%-6% of all gastrointestinal tract neoplasms. Due to the rarity of these lesions, the low index of clinical suspicion, and the inadequate radiologic examinations or incorrect interpretation of radiologic findings, a delay in diagnosis of 6-8 months from the first symptoms often occurs. Even if conventional enteroclysis and capsule endoscopy are the most common procedures used to accurately depict the bowel lumen and mucosal surface, their use in evaluating the mural and extramural extents of small-bowel tumors is limited...
