Approximately 75% of patients undergoing capsule endoscopy for obscure GI bleeding will have an abnormality found in the small intestine.
Dr Warwick Selby and colleague from Australia reviewed a prospective database of 140 patients undergoing capsule endoscopy for obscure GI bleeding.
Patients at a single center, with a definite or likely cause of bleeding within reach of conventional upper or lower GI endoscopy were identified.
The research team describes 9 patients of 140 with obscure bleeding, where the source of blood loss was found in the stomach or the colon at capsule endoscopy.
The team noted that 3 patients had gastric antral vascular ectasia and another an inflamed pyloric canal polyp.
|Capsule endoscopy identified 2 bleeding cecal carcinomas missed at previous colonoscopies|
The research team observed that 2 patients had actively bleeding cecal carcinoma, missed at previous colonoscopies.
In addition, 2 others were identified by the team to have bleeding cecal angiodysplasia.
The final patient had severe nonspecific cecal inflammation.
The team's identification of these lesions was aided by the suspected blood indicator.
The researchers reported that all patients underwent endoscopic therapy or surgery for their non-small-bowel lesions.
Dr Selby and colleague concludes, “Like push enteroscopy, capsule endoscopy also can identify lesions within reach of conventional endoscopy and colonoscopy.”
“These subsequently can be treated successfully, however, the reasons why these lesions have been missed are unclear.”
