Comparative Effectiveness of Roux-en-Y Gastric Bypass and Sleeve Gastrectomy for Treatment of Type II Diabetes: A Review of Reviews

July 27, 2017 Medical Technology Directory

Purpose of Technology: Roux-en-Y gastric bypass is a surgery that reduces the capacity of the stomach and the length of the small intestine through which food travels. Sleeve gastrectomy reduces stomach capacity only. These bariatric surgeries are widely accepted as very effective for weight loss in people with morbid obesity; however, recent research has explored their use for the treatment of type II diabetes mellitus. Rationale: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) bariatric surgeries may improve type II diabetes mellitus (T2DM) by multiple mechanisms, including induction of weight loss and hormonal changes. Controversy: RYGB has been considered the first choice...

Comparative Effectiveness Review of Cryoablation for Salvage Treatment of Recurrent Prostate Cancer Following Radiotherapy

July 27, 2017 Medical Technology Directory

Purpose of Technology: Cryoablation of the prostate gland provides a minimally invasive treatment option for the management of localized prostate cancer. The technique uses percutaneously inserted cryoprobes to freeze and thereby destroy cancerous prostate tissue. Rationale: The goals of minimally invasive cryoablation for salvage treatment of localized recurrences of prostate cancer after primary radiotherapy (RT) are to use focused cryoablation energy to ablate the entire prostate gland or the cancer-containing part of the gland and achieve complete tumor control to improve survival. Controversy: Locally ablative therapies such as cryoablation may have less morbidity compared with other treatment options for localized recurrence of...

Comparative Effectiveness Review of Cryoablation for Primary Treatment of Localized Prostate Cancer

July 27, 2017 Medical Technology Directory

The publication date for this report is June 8, 2017, with a corrigendum issued on July 27, 2017. See Publication History for details. Purpose of Technology: Cryoablation of the prostate gland provides a minimally invasive treatment option for the management of localized prostate cancer. The technique uses percutaneously inserted cryoprobes to freeze and, thereby, destroy cancerous prostate tissue. This outpatient procedure has been evaluated for patients with prostate cancer who prefer a less invasive option than prostatectomy or who are not appropriate surgical candidates. Rationale: The goals of the minimally invasive cryoablation treatment for localized prostate cancer are to use focused cryoablation...

Comparative Effectiveness Review of First-Generation Autologous Chondrocyte Implantation of the Knee

July 13, 2017 Medical Technology Directory

Purpose of Technology: Autologous chondrocyte implantation (ACI) or transplantation is a form of tissue engineering that creates a graft from a patient’s own cartilage cells to repair defects in articular cartilage. The procedure involves the collection of cartilage cells, which are grown in a laboratory to create new cartilage tissue. This new tissue is then implanted into the defect, with the goal of improving the quality of cartilage repair. Rationale: ACI places durable, living cartilage at sites within joints that have high levels of physical stress due to weight bearing and motion.  Controversy: ACI requires surgery to collect cells and a...

Comparative Effectiveness Review of Second- and Third-Generation Autologous Chondrocyte Implantation of the Knee

July 13, 2017 Medical Technology Directory

Purpose of Technology: Autologous chondrocyte implantation (ACI) or transplantation is a form of tissue engineering that creates a graft from a patient’s own cartilage cells to repair defects in articular cartilage. The procedure involves the collection of cartilage cells, which are grown in a laboratory to create new cartilage tissue. This new tissue is implanted into the defect, with the goal of improving the quality of cartilage repair. Rationale: ACI places durable, living cartilage at sites within joints that have high levels of physical stress due to weight bearing and motion. Controversy: ACI requires surgery to collect cells and a second surgery...
