Achalasia: Diagnosis and Management.

Achalasia is an incurable condition of the esophagus involving the inflammation and degeneration of inhibitory neurons of the lower esophageal sphincter (LES) resulting in failure of the LES to relax. Typical symptoms of achalasia are dysphagia, retrosternal chest pain, regurgitation, and weight loss. Three studies are typically required for the diagnosis of achalasia: barium swallow, high-resolution esophageal manometry, and esophagogastroduodenoscopy.

Single port laparoscopic cholecystectomy with the TriPort system: a case report.

Single port access surgery may be the next generation of minimally invasive surgery. This study reports a recent experience with the TriPort system (trademark pending, Advanced Surgical Concepts, Wicklow, Ireland) to perform a laparoscopic cholecystectomy via a single peri-umbilical incision. To the authors' knowledge, this is one of the first cases of single port laparoscopic cholecystectomy ever performed with this device in the United States.
