The researchers studied 72 patients with confirmed small bowel tumors. Of those patients, 71 percent experienced gastrointestinal bleeding of an obscure source, and 29 percent suffered from anemia, polyposis and/or abdominal pain. These 72 patients had previously undergone 334 negative procedures (an average of 4.6 each) including 115 colonoscopies, 111 upper endoscopies, 32 small bowel follow through procedures, 24 enteroscopies, 17 CT scans, 16 enteroclysis procedures, six nuclear bleeding scans, five angiographies, five plain abdominal X-rays, one abdominal ultrasound, one Meckel's scan, and one laparoscopy.
Researchers used the "M2A© Capsule" also known as the "Pill Camera" made by Given Imaging, Yoqneam, Israel. The findings from the capsule examinations included 73 small bowel tumors, one cecal tumor and one gastric tumor. Of these 65 percent were malignant, including adenocarcinomasc, carcinoids, melanomas, lymphomas and sarcomas.
"Small bowel tumors are traditionally difficult to diagnose because of their endoscopic inaccessibility," explains Gregory Schwartz, M.D., one of the researchers. "This has been overcome by the use of capsule endoscopy."
