BACKGROUND: Anodal transcranial direct current stimulation (tDCS) has demonstrated effects on corticobulbar excitability and swallowing function as assessed via clinical rating scales in stroke cohorts. Biomechanical effects of anodal tDCS on swallowing remain largely unexplored. We investigated how anodal tDCS applied over the floor of mouth (FOM) representation on the primary motor cortex affects swallowing biomechanics in healthy participants. METHODS: Anodal and sham tDCS were applied for 20 minutes at 1...

BACKGROUND: Intestinal metaplasia represents an esophageal mucosal transformation due to uncontrolled gastroesophageal reflux disease. Fundoplication has been shown to lead to regression of disease. Magnetic sphincter augmentation is an alternative to fundoplication that effectively treats reflux disease. Initially, patients with intestinal metaplasia were not considered candidates for device placement, so outcomes in these patients are unknown. METHODS: A retrospective review of all patients who underwent magnetic sphincter augmentation device placement between 2007 and 2017 was performed...

BACKGROUND AND AIMS: GERD patients frequently complain of regurgitation of gastric contents. Medical therapy with proton-pump inhibitors (PPIs) is frequently ineffective in alleviating regurgitation symptoms, as PPIs do nothing to restore a weak lower esophageal sphincter. Our aim was to compare effectiveness of increased PPI dosing with laparoscopic magnetic sphincter augmentation (MSA) in patients with moderate-to-severe regurgitation despite once-daily PPI therapy. METHODS: One hundred fifty-two GERD patients >21 years with moderate-to-severe regurgitation despite 8weeks of once-daily PPI therapy were prospectively enrolled at 21 U...

A total laparoscopic fundoplication has become the procedure of choice for the surgical treatment of gastroesophageal reflux disease in patients with normal esophageal motility, with reduced postoperative pain, faster recovery and similar long-term outcomes compared to conventional open total fundoplication. Most controversial surgical aspects are the division of the short gastric vessels and the insertion of a bougie to calibrate the wrap. The anterior 180° and the posterior partial fundoplications lead to similar control of heartburn when compared to total fundoplication with lower risk of dysphagia...

Use of the magnetic sphincter augmentation (MSA) device for the laparoscopic treatment of gastroesophageal reflux disease is increasing since the first clinical implant performed a decade ago. The MSA procedure is a minimally invasive and highly standardized surgical option for patients who are partially responders to proton-pump inhibitors, which have troublesome regurgitation or develop progressive symptoms despite continuous medical therapy. The procedure has proven to be highly effective in improving typical reflux symptoms, reducing the use of proton-pump inhibitors, and decreasing esophageal acid exposure...

BACKGROUND: The magnetic sphincter augmentation (MSA) device was initially implanted with minimal hiatal dissection (MHD) at the diaphragmatic hiatus. Due to concern of possible MSA device dysfunction if herniated into an occult or small hiatal hernia, and increased understanding to the role of defective crura in reflux disease, the operative procedure was changed to planned obligatory dissection (OD) of the hiatus at the time of all implantations. METHODS: Between December 2012 and September 2016, 182 patients underwent MSA implant at a single medical center and have complete records available for review through September 2017...

Antireflux surgery anatomically restores the antireflux barrier and is a therapeutic option for proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease or PPI intolerance. Laparoscopic fundoplication is the standard antireflux surgery, though its popularity has declined due to concerns regarding wrap durability and adverse events. As the esophagogastric junction is an anatomically complex and dynamic area subject to mechanical stress, wraps are susceptible to disruption, herniation or slippage...

BACKGROUND: Vagus nerve stimulation (VNS) is an emerging electroceutical therapy for remedying gastric disorders that are poorly managed by pharmacological treatments and/or dietary changes. Such therapy seems promising as the vagovagal neurocircuitry modulates the enteric nervous system to influence gastric functions. METHODS: Here, the modulatory effects of left cervical VNS on gastric emptying in rats were quantified using a (i) feeding protocol in which the animal voluntarily consumed a postfast, gadolinium-labeled meal and (ii) a non-invasive imaging method to measure antral motility, pyloric activity and gastric emptying based on contrast-enhanced magnetic resonance imaging (MRI) and computer-assisted image processing pipelines...
