Arthroscopic Mechanical Chondroplasty of the Knee Is Beneficial for Treatment of Focal Cartilage Lesions in the Absence of Concurrent Pathology.

Background: Articular cartilage lacks the ability for intrinsic repair after acute injury, and focal articular cartilage lesions cause significant morbidity worldwide. Arthroscopic debridement (chondroplasty) represents the majority of cartilage procedures of the knee; however, limited data exist regarding outcomes after chondroplasty performed in isolation of concurrent procedures or not as a primary treatment for osteoarthritis (OA).

Hypothesis: Arthroscopic mechanical chondroplasty is beneficial for patients with a focal cartilage lesion of the knee in the absence of meniscal pathology or OA.

The Durability of Endoscopic Therapy for Treatment of Barrett's Metaplasia, Dysplasia, and Mucosal Cancer After Nissen Fundoplication.

Introduction: Radiofrequency ablation (RFA) ± endoscopic resection (EMR) is an established treatment strategy for neoplastic Barrett's and intramucosal cancer. Most patients are managed with proton pump inhibitors. The incidence of recurrent Barrett's metaplasia, dysplasia, or cancer after complete eradication is up to 43 % using this strategy.

Peroral endoscopic myotomy (POEM) for esophageal primary motility disorders: analysis of 100 consecutive patients.

Introduction: Peroral endoscopic myotomy (POEM) is a flexible endoscopic approach to the lower esophageal sphincter (LES) providing access for a myotomy to relieve dysphagia. The technique has been adopted worldwide due to reports of excellent short-term clinical outcomes. We report on a consecutive patient cohort with clinical and objective outcomes representing the establishment of a POEM program within a busy esophageal surgical practice.
