Intraoperative enteroscopy.

Current options for the diagnosis and management of small bowel lesions include push enteroscopy (PE), video capsule endoscopy (VCE), single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), and intraoperative enteroscopy (IOE). IOE, the ultimate diagnostic and therapeutic modality for small bowel disorders, is a major surgical and endoscopic procedure. It should be reserved for cases that cannot be managed with others modalities because of the difficulties of the procedure and significant morbidity.

Percutaneously adjustable pulmonary artery band.

Background: Pulmonary artery banding, originally introduced to palliate increased pulmonary blood flow, is now primarily used for complex congenital cardiac defects with a prohibitive risk in the early repair, such as tricuspid atresia, or occasionally to prepare the left ventricle for eventual arterial switch. Conventional banding is, however, often poorly tolerated, and the precise adjustment required to reduced pulmonary blood flow or sufficiently challenge the left ventricle is difficult and can cause life-threatening hemodynamic changes.

Methods: We designed a band that allows accurate tightening and is reversible during the operation and at the bedside with the chest closed, allowing precise gradual adjustment over days, thereby minimizing cardiovascular instability.
