Three-year results of a multicenter prospective study of transoral incisionless fundoplication.

Background: To date, there are no long-term data on the use of transoral incisionless fundoplication (TIF) for the treatment of chronic gastroesophageal reflux disease (GERD). We sought to prospectively evaluate the long-term safety and durability of TIF in a multi-center setting.

Methods: A longitudinal per protocol (PP) and a modified intention-to-treat (mITT) analysis at 1 and 3 years consisted of symptom evaluation using the GERD health-related quality of life (GERD-HRQL) questionnaire, medication use, upper gastrointestinal endoscopy, and pH-metry.

Antireflux transoral incisionless fundoplication using EsophyX: 12-month results of a prospective multicenter study.

Background: A novel transoral incisionless fundoplication (TIF) procedure using the EsophyX system with SerosaFuse fasteners was designed to reconstruct a full-thickness valve at the gastroesophageal junction through tailored delivery of multiple fasteners during a single-device insertion. The safety and efficacy of TIF for treating gastroesophageal reflux disease (GERD) were evaluated in a prospective multicenter trial.

Methods: Patients (n = 86) with chronic GERD treated with proton pump inhibitors (PPIs) were enrolled.

Clinical and six-month angiographic evaluation of coronary arterial graft interrupted anastomoses by use of a self-closing clip device: a multicenter prospective clinical trial.

Objectives: To evaluate the safety and effectiveness of a self-closing surgical clip with an interrupted technique in left internal thoracic artery to left anterior descending artery bypass grafting.

Methods: Eighty-two patients were enrolled and treated (February 2000 through August 2001) in a prospective, nonrandomized, multicenter trial. Left internal thoracic artery to left anterior descending artery anastomoses were performed in 60 off-pump coronary artery bypasses (73%), 12 conventional coronary artery bypass grafting (15%), and 10 minimally invasive direct coronary artery bypass (12%) procedures.

Six-month angiographic evaluation of beating-heart coronary arterial graft interrupted anastomoses using the coalescent U-CLIP anastomotic device: a prospective clinical study.

Background: Interrupted suture technique avoids the "purse string" and puckering effects frequently seen with continuous suture techniques and should represent the standard of care in the creation of high-quality vascular anastomoses. This clinical study evaluated the safety and effectiveness of a self-closing surgical clip (Coalescent Surgical U-CLIP Anastomotic Device [U-CLIP]) designed to facilitate this interrupted technique. Left internal mammary artery (LIMA) to left anterior descending (LAD) coronary bypass grafting was studied.

Alterations in Phagocyte Function and Periodontal Infection.

A review of phagocytic cells-polymorphonuclear leukocytes and monocytes-in the inflammatory process is presented. Examples of phagocyte defect-related pathology serve as a framework for understanding the role of these cells in periodontal infection. The role of alterations in neutrophil function in localized juvenile periodontitis is presented as a model system for understanding periodontal pathology as a result of host-related functional abnormalities.
