Roux-en-Y Gastric Bypass for Treatment of Type II Diabetes: A Review of Reviews

May 25, 2017 Medical Technology Directory

Purpose of Technology: Roux-en-Y gastric bypass (RYGB) is surgery that reduces the capacity of the stomach and the length of the small intestine through which food travels. RYGB is widely accepted as very effective for weight loss in people with morbid obesity; however, recent research has explored the use of RYGB for the treatment of type II diabetes, including in less obese patients. Rationale: In addition to being an effective form of weight loss for severely obese patients, bariatric surgery has been linked to significant improvements or complete resolution of obesity-associated comorbidities, including Type II diabetes mellitus (T2DM), in most patients....

Surgical Treatment for Lymphedema: A Review of Reviews

May 11, 2017 Medical Technology Directory

Purpose of Technology: Lymphedema is the swelling of limbs caused by fluid accumulation, most commonly due to lymphatic injury caused by cancer treatment. Conservative management may confer insufficient control or be ineffective altogether, especially if lymphedema is advanced. Multiple surgical techniques have been developed with the intent of providing an effective lymphedema treatment option when conservative management fails. Rationale: Nonsurgical treatments are intensive and require extensive and time-consuming ongoing intervention, yet for some patients confers inadequate lymphedema control. Surgical intervention to restore lymphatic flow or remove excess tissue may provide a more effective, long-term treatment option. Controversy: Surgery is inherently invasive and...

Arthroscopic Hip Surgery for Femoroacetabular Impingement

May 4, 2017 Medical Technology Directory

Purpose of Technology: Femoroacetabular impingement (FAI) occurs due to an altered or suboptimal shape of the femoral neck, leading repetitive contact and breakdown of the cartilage around the rim of the hip joint. Several different types of arthroscopic surgery have been developed to reshape bone and remove or repair damaged cartilage with the goal of restoring normal hip function. Rationale: Hip surgery may be necessary for FAI to relieve pain, enable full range of motion (ROM), and to prevent joint degeneration and progression to arthritis. Arthroscopic surgeries have been developed for treatment of FAI to avoid the trauma and prolonged recovery...

Comparative Effectiveness Review of Mosaicplasty for Treatment of Articular Cartilage Injuries

May 4, 2017 Medical Technology Directory

Purpose of Technology: Mosaicplasty is a technique for repairing cartilage in weight-bearing joints that have been damaged by trauma or degenerative processes. It consists of removing small cylinders of cartilage or bone and cartilage from low- or non-weight-bearing sites in the affected joint or another joint in the patient. Rationale: Mosaicplasty places durable, living cartilage at sites within joints that have high levels of physical stress due to weight bearing and motion.    Controversy: Mosaicplasty is a complex procedure that requires recreation of a mobile, load-bearing surface. Inaccurate reconstruction can create uneven physical stresses that accelerate breakdown of the transplanted cartilage....

Intravenous Lidocaine Infusion for Neuropathic Pain: A Review of Reviews

April 20, 2017 Medical Technology Directory

Purpose of Technology: Lidocaine hydrochloride is a local anesthetic with antiarrhythmic properties that may hold utility in the treatment of select patients with intractable neuropathic pain. Intravenous lidocaine helps to suppress spontaneous ectopic discharges of damaged nerves without blocking normal neuronal conduction, which in part underlies its analgesic effect. Rationale: Opioid prescriptions have increased dramatically in use over the past 2 decades, and opioid use disorder is now a major health problem in the United States. Opioids are partially effective for pain relief in the short-term and highly variable for long-term pain, and their chronic use is associated with tolerance, dependency,...
