Abstract: | Small bowel tumors are difficult to diagnose because of their endoscopic inaccessibility. This has been overcome by the use
of the Pillcam™ SB capsule (Given Imaging, Yoqneam, Israel). The purpose of this report is to describe the largest series
of patients with small bowel tumors detected by capsule endoscopy. Eighty six patients were derived from the Given Imaging
clinical database on a survey of Pillcam™ SB capsule users who were diagnosed with 87 small bowel tumors, 1 cecal tumor, and
1 gastric tumor. The population consisted of 55 males and 31 females. 69% of patients were referred for capsule endoscopy
for obscure gastrointestinal bleeding (59/86 patients) and 31% (27/86 patients) were referred for other indications including
anemia, polyposis, and abdominal pain. All patients have histologically confirmed tumors. Eighty six patients reported 395
previous negative procedures (average of 4.6 per patient). Malignant tumors comprised 61% (54/89) and benign 39% (35/89).
Of the 87 reported small bowel tumors, 4 were identified in the duodenum, 43 tumors were identified in the jejunum, 18 tumors
were identified in the ileum, and 22 tumors were located in the mid to distal small bowel. The most common malignant tumors
were adenocarcinoma, carcinoids, melanomas, lymphomas, and sarcomas. The most common benign tumors were GIST, hemangiomas,
hamartomas, adenomas, and granulation tissue polyps. Capsule endoscopy is the diagnostic procedure of choice in patients with
suspected small bowel tumors. |
