How can lesions identified by capsule endoscopy be further defined before performing surgery

How can lesions identified by capsule endoscopy be further defined before performing surgery? 

Capsule endoscopy often does not permit an ideal view of lesions because the capsule tumbles through the small bowel naturally by peristalsis without any opportunity to adjust position to obtain a better view. Thus lesions may be seen peripherally on only one videophotograph. Capsule endoscopy also does not permit cleaning the photographic lens or clearing the endoscopic field to improve visualization. Capsule endoscopy also does not permit biopsy or brushing of lesions for cytologic or pathologic analysis. It is solely diagnostic and not therapeutic. Single-balloon or double-balloon enteroscopy can better view small intestinal lesions identified by capsule endoscopy. Lesions can be biopsied or ablated at double-balloon enteroscopy.
