Capsule Endoscopy for the Diagnosis of Small Bowel Crohn’s Disease

March 23, 2017 Medical Technology Directory

Purpose of Technology: Capsule endoscopy (CE), also called wireless capsule endoscopy or video capsule endoscopy, is a minimally invasive procedure in which the patient swallows a multivitamin-sized capsule containing a miniaturized video camera, light transmitter, and batteries. The camera takes a video recording of the mucosal lining of the esophagus, small bowel, and/or colon as the capsule moves through the gastrointestinal (GI) tract. Rationale: CE enables visualization of the entire small bowel with no need to sedate or anesthetize the patient and with little supervision or effort needed by the nurse or physician who monitors the procedure. Controversy: Although CE is minimally...

Occupational Therapy for Attention-Deficit/Hyperactivity Disorder (ADHD)

March 16, 2017 Medical Technology Directory

Purpose of Technology: Occupational therapy (OT) for attention-deficit/hyperactivity disorder (ADHD) encompasses a wide array of interventions, with the aim of increasing function in all aspects of life and settings (school, home, etc.). Specific interventions vary and are determined by the occupational therapist depending on the presenting problems, deficits, and the therapist’s determination of the best course of treatment. OT interventions for ADHD can be classified as impairment oriented or performance oriented. Rationale: The impairment-oriented interventions for ADHD are sensory based and rooted in sensory integration therapy. In performance-oriented interventions, it is theorized that in children with ADHD, executive dysfunction hinders the...

Percutaneous Kyphoplasty for Osteoporotic Vertebral Compression Fractures

March 9, 2017 Medical Technology Directory

Purpose of Technology: Percutaneous kyphoplasty (KP) is an interventional procedure used to treat painful vertebral compression fractures related to osteoporosis. The procedure involves guided insertion of an inflatable bone tamp into the partially collapsed vertebral body. Once in place, the balloon is expanded to the desired height and removed. An acrylic polymer is then injected into the space, where it hardens and binds to the vertebral body. Rationale: KP is intended to relieve pain, stabilize the bone, prevent additional fractures, and potentially restore vertebral height. Controversy: Evidence suggests that vertebral augmentation procedures, including KP and vertebroplasty (VP), may provide superior outcomes to...

Hydrogen Breath Tests for Diagnosis of Small Intestinal Bacterial Overgrowth in Functional Bowel Disorders

March 9, 2017 Medical Technology Directory

Purpose of Technology: Hydrogen breath testing (HBT) may be used to identify small intestinal bacterial overgrowth (SIBO) in predisposed patients by assessing changes in hydrogen (H2) expiration following administration of glucose, lactulose, or other compounds. Rationale: When SIBO is present, fermentation by bacteria in the small intestine produces a large amount of H2, the magnitude and pattern of which may be used to distinguish SIBO-positive patients from SIBO-negative patients. Human cells are not capable of producing H2 on their own. Controversy: There are several potential sources for false HBT results, including: failure to adhere to a low-fiber diet the day before the...

Antibiotic-Impregnated Bone Cement for Knee Arthroplasty

February 16, 2017 Medical Technology Directory

Purpose of Technology: Antibiotic bone cement (ABC) is a type of curable polymethylmethacrylate preparation created by adding various antibiotic medications to plain, nonmedicated bone cement. Most commonly, ABC is used to treat infected total joint prostheses as part of a revision arthroplasty, but its use as antibiotic prophylaxis in primary joint arthroplasty is increasing. Rationale: The usage of ABC at the arthroplasty site may be useful in maintaining a locally high level of antibiotic drug concentration. Controversy: Controversial issues related to the clinical use of ABCs in TKA include the safety and effectiveness of ABCs compared with other fixation methods, optimal antibiotic...
