Comparative Effectiveness Review of Peroral Endoscopic Myotomy for Treatment of Esophageal Achalasia

December 3, 2019 Medical Technology Directory

Health Problem: Esophageal achalasia (EA) is an uncommon motility disorder of unknown etiology that is characterized by increased lower esophageal sphincter (LES) pressure and esophageal aperistalsis. Treatment for EA includes both conservative treatment options, such as pharmaceutical therapies or botulinum toxin injection, and invasive options, such as pneumatic dilation or surgery. Technology Description: Peroral endoscopic myotomy (POEM) is a natural orifice transluminal endoscopic surgery technique. The technique involves guiding an endoscope through the esophagus, making an incision in the mucosa, creating a submucosal tunnel for access to the lower esophagus and gastroesophageal junction, and cutting the muscle fibers in the lower...

Colon Capsule Endoscopy for Colorectal Cancer Screening, Diagnosis, and Surveillance

November 25, 2019 Medical Technology Directory

Health Problem: Colorectal cancer (CRC) is the second leading cause of cancer death in men and the third in women. Although screening for CRC has been found to reduce CRC mortality, many patients do not undergo the recommended screening. Technology Description: Colon capsule endoscopy (CCE) is a minimally invasive technique that uses a wireless, miniature camera to capture images of the interior lining of the colon and rectum as the capsule moves through the gastrointestinal tract. CCE is intended for use as an alternative to conventional colonoscopy (CC) for the diagnosis and surveillance of adults with signs and symptoms of disease...

Comparative Effectiveness Review of Cold Compression Therapy for Patients Undergoing Orthopedic Procedures to Major Joints (Other than Knee)

November 22, 2019 Medical Technology Directory

Health Problem: Acute postoperative pain and swelling is common following orthopedic procedures. Inadequately controlled pain negatively affects quality of life and recovery of function and may result in an increase in morbidity, recovery time, opioid use, and risk of complications or persistent postsurgical pain. Technology Description: Cold compression (CC) therapy involves the simultaneous application of cold and compression through a device that generally consists of a cuff or wrap and a cooler with or without a pump. CC therapy is proposed to act synergistically with cold to promote vasoconstriction to relieve edema, swelling, and muscle spasms. The intended benefits of CC...

Deep Brain Stimulation of the Anterior Nucleus of the Thalamus for Treatment of Refractory Epilepsy

November 14, 2019 Medical Technology Directory

Health Problem: Epilepsy is one of the most common neurological disorders in the United States and has a prevalence of approximately 3 million adults and 470,000 children. Management generally involves treatment with antiepileptic drugs (AEDs), but for approximately 30% of patients, seizures will remain uncontrolled by medical therapy. In these cases other, more invasive, procedures might be warranted, including intracranial surgery or neurostimulation with vagus nerve stimulation (VNS) or deep brain stimulation (DBS). Technology Description: DBS is used as an adjunct to antiepileptic medications for partial-onset seizures (with or without secondary generalization) uncontrolled by medical management alone. DBS involves intracranial implantation of electrodes...

Transcutaneous Bone–Anchored Hearing Aids

November 12, 2019 Medical Technology Directory

Health Problem: In the United States, it is estimated that 48 million adults have some type of hearing loss. Hearing loss can be broadly classified as sensorineural (inner ear), conductive (external and middle ear), or mixed. Technology Description: Transcutaneous bone–anchored hearing aids (tBAHAs) transmit sound vibrations from the environment to the inner ear by direct bone conduction through the skull. Unlike percutaneous BAHA (pBAHA) systems that employ a skin-penetrating implant, tBAHA systems use a magnetic connection to join the sound processor and the implant, leaving the skin intact. tBAHAs are intended to improve hearing acuity in individuals who have sensorineural deafness and unilateral...
