BACKGROUND Guidelines recommend instruction and motivation during anorectal manometry; however, its impact on findings has not been reported. This study assessed the effects of standard versus enhanced instruction and verbal feedback on the results of anorectal manometry. METHODS High-resolution manometry was performed by a solid-state catheter with 10 circumferential sensors at 6 mm separati...

TO THE EDITOR: Abdallah and Fass recently reported an interesting case of a patient with dysphagia who was initially diagnosed with Jackhammer esophagus (JE) and progressed to type 2 achalasia over the course of approximately 2 years. We read this report with great interest as our group has studied the natural course of JE and has also found progression of JE to achalasia, which we reported pre...

PURPOSE To determine the biocompatibility of a new wireless intraocular pressure (IOP) transducer (WIT) in rabbit eyes and to correlate its measurements with other pressure-measuring devices. METHODS The WIT is a ring-shaped intraocular device that allows wireless IOP measurements through radiofrequency. It was implanted into six eyes of New Zealand White rabbits after extracapsular lens extr...

Sphincter of Oddi dysfunction (SOD) is a syndrome of chronic biliary pain or recurrent pancreatitis due to functional obstruction of pancreaticobiliary flow at the level of the sphincter of Oddi. The Milwaukee classification stratifies patients according to their clinical picture based on elevated liver enzymes, dilated common bile duct and presence of abdominal pain. Type I patients have pain ...

BACKGROUND The purpose of this study is to evaluate the use of Tono-Pen XL in measuring IOP during the application of a suction ring in rabbit eyes with manometrically controlled IOP. METHODS Tono-Pen XL was calibrated against direct manometry in 10 rabbit eyes. A suction ring was then applied in 4 rabbit eyes and the IOP was determined manometrically during suction ring application at 350 mm...

Anorectal manometry measures the pressures of the anal sphincter muscles, sensation in rectum, and the neural reflexes that are needed for normal bowel movements. This test is mainly performed to evaluate patients with constipation or fecal incontinence but is also useful for pre/post surgical evaluation of anal sphincter tone, functional anorectal pain, pelvic floor dyssynergia and diagnosis o...

BACKGROUND Sleeve gastrectomy may alter esophageal motility and lower esophageal sphincter pressure. AIM To detect manometric changings in the esophagus and lower esophageal sphincter before and after sleeve gastrectomy in order to select patients who could develop postoperative esophageal motilitity disorders and lower esophageal sphincter pressure modifications. METHODS Seventy-three pati...

BACKGROUND The transient dysphagia after fundoplication is common and most often disappears until six weeks postoperatively. AIM Analyze a group of patients who presented late and persistent dysphagia postoperatively. METHODS Forty-one patients after Nissen fundoplication, 14 male and 27 female, mean age 48 year, were evaluated based on medical history, esophagogastroduodenoscopy, contrast ...
