The diagnosis of small-bowel tumors is challenging due to their low incidence, nonspecific presentation, and limitations of traditional endoscopic techniques. In our study, we examined the utility of the mucosal protrusion angle in differentiating between true submucosal masses and bulges of the small bowel on video capsule endoscopy. We retrospectively reviewed video capsule endoscopies of 34 patients who had suspected small-bowel lesions between 2002 and 2017. Mucosal protrusion angles were defined as the angle between the small-bowel protruding lesion and surrounding mucosa and were measured using a protractor placed on a computer screen. We found that 25 patients were found to have true submucosal masses based on pathology and 9 patients had innocent bulges due to extrinsic compression. True submucosal masses had an average measured protrusion angle of 45.7 degrees ± 20.8 whereas innocent bulges had an average protrusion angle of 108.6 degrees ± 16.3 (p < 0.0001; unpaired t-test). Acute angle of protrusion accurately discriminated between true submucosal masses and extrinsic compression bulges on Fisher’s exact test (p = 0.0001). Our findings suggest that mucosal protrusion angle is a simple and useful tool for differentiating between true masses and innocent bulges of the small bowel.

Peutz Jeghers Syndrome

Until 2001, the nonsurgical evaluation of the small intestine was largely limited to the use of radiologic imaging (e.g., small bowel follow-through or enteroclysis). With the now widespread availability of video capsule endoscopy and deep enteroscopy since 2001, we are now able to visualize the length and most of the mucosa of the small intestine and manage small bowel lesions that were previously inaccessible except by surgical intervention. This review serves as an overview for these two procedures, detailing the indications and contraindications, proper timing of the procedure, technical aspects of the devices themselves, possible complications, and outcomes. Figures show endoscopic images that demonstrate multiple angioectasias, bleeding during capsule endoscopy, active Crohn disease of the small bowel, severe mucosal scalloping, small bowel carcinoid tumor, small bowel polyp associated with Peutz-Jeghers syndrome, and nonsteroidal antiinflammatory drug enteropathy; serial x-rays of a patient with a patency capsule retained inside the small intestine; a computer image showing the distribution of small bowel tumors; and a pie chart displaying the breakdown of the distribution of benign and malignant tumors that can be found in the small intestine. Videos show multiple angioectasias, bleeding during capsule endoscopy, active Crohn disease of the small bowel, small bowel carcinoid tumor, and small bowel polyp associated with Peutz-Jeghers syndrome. This review contains 10 highly rendered figures, 5 videos, and 50 references.

<p><strong>Purpose:</strong> Despite being rare entities, the incidence of malignant small bowel tumors seems to be rising. The development of capsule endoscopy and balloon assisted enteroscopy provided an advance in the assessment of small bowel lesions. We aim to describe the clinical and pathological characteristics of patients with small bowel cancer and ascertain what roles these endoscopic techniques currently have.<br /><strong>Material and Methods:</strong> A retrospective study of patients diagnosed with small bowel cancer, from January 2010 to October 2014, was performed. The data was submitted to statistical analysis.<br /><strong>Results:</strong> Of the 28 diagnosed patients, 54% were female. The mean age at diagnosis was 61 years. Adenocarcinoma was the most frequent tumor (n = 11), followed by sarcoma (n = 6), lymphoma (n = 6) and neuroendocrine tumors (n = 3). The main form of presentation was related to blood loss or intestinal obstruction. By the time of diagnosis, 46% of patients had distant metastasis/ unresectable cancer. Most of the tumors were diagnosed by endoscopic (41%) or imaging techniques (35%). In the first year after diagnosis, 29% of patients died. In multivariate analysis, adenocarcinoma remained an independent factor for worse survival.<br /><strong>Discussion:</strong> Patients with adenocarcinoma presented at late stages and with unresectable tumors, contributing to a worse outcome. A high degree of clinical suspicion for the diagnosis of small bowel cancer is necessary.<br /><strong>Conclusion: </strong>The characteristics of the patients were generally consistent with those described in the literature. Capsule endoscopy and balloon assisted enteroscopy are useful in the diagnosis, management and surveillance of small bowel cancer.</p>
