Surgery for Obesity and Related Diseases > 2016 > 12 > 1 > 62-69

At present, no objective data are available on the effect of omega-loop gastric bypass (OGB) on gastroesophageal junction and reflux.To evaluate the possible effects of OGB on esophageal motor function and a possible increase in gastroesophageal reflux.University Hospital, Italy; Public Hospital, Italy.Patients underwent clinical assessment for reflux symptoms, and endoscopy plus high-resolution impedance...

Clinical Gastroenterology and Hepatology > 2015 > 13 > 6 > 1075-1081

Mucosal integrity can be assessed in patients with gastroesophageal reflux disease (GERD) by measuring intraluminal baseline impedance (BI). However, it is not clear whether BI is abnormal in patients with functional heartburn (FH), or can be used to distinguish them from patients with GERD. We compared differences in BI between patients with FH vs GERD.We performed a prospective study of 52 patients...

Sleeve Gastrectomy and Development of “De Novo” Gastroesophageal Reflux

Obesity Surgery > 2014 > 24 > 1 > 71-77

Background Sleeve gastrectomy (SG) is currently gaining popularity due to an excellent efficacy combined to minimal anatomic changes. However, some concerns have been raised on increased risk of postoperative gastroesophageal reflux disease (GERD) due to gastric fundus removal, section of the sling muscular fibers of gastroesophageal junction, reduced antral pump function, and gastric volume. We undertook...

Swallowing Activity Assessed by Ambulatory Impedance-pH Monitoring Predicts Awake and Asleep Periods at Night

D. Pohl, F. Arevalo, E. Singh, J. Freeman, more

Digestive Diseases and Sciences > 2013 > 58 > 4 > 1049-1053

Introduction Voluntary muscle activity, including swallowing, decreases during the night. The association between nocturnal awakenings and swallowing activity is under-researched with limited information on the frequency of swallows during awake and asleep periods. Aim The aim of this study was to assess nocturnal swallowing activity and identify a cut-off predicting awake and asleep periods. ...

Impedance pH Confirms the Relationship Between GERD and BMI

Digestive Diseases and Sciences > 2012 > 57 > 7 > 1875-1879

Background During the last 20 years the prevalence of both gastroesophageal reflux disease (GERD) and obesity has been increasing in the United States. The pathophysiology of GERD is multifactorial and its relationship with obesity is still not well understood. Aim To evaluate the association between BMI and GERD as detected by multichannel intraluminal impedance-pH (MII-pH) monitoring. Methods...

Overweight is a risk factor for both erosive and non-erosive reflux disease

Digestive and Liver Disease > 2011 > 43 > 12 > 940-945

Studies have reported that the association between overweight and erosive oesophagitis is very strong, whilst seeming less consistent with non-erosive reflux disease.We have hypothesized that this difference may be due to the heterogeneity of endoscopy-negative population.We studied 81 patients with erosive oesophagitis, 48 controls and 295 endoscopy-negative patients classified by impedance-pH-testing...

Combined Esophageal Multichannel Intraluminal Impedance and pH Monitoring (MII -pH) in the Diagnostics and Treatment of Gastroesophageal Reflux Disease and its Complications

Wioletta Masiak, Grzegorz Wallner, Jan Wallner, Tomasz Pedowski, more

Polish Journal of Surgery > 2011 > 83 > 9 > 488-496

The technique of 24-hour esophageal multichannel intraluminal impedance monitoring combined with pH-metry (MII-pH) is currently considered to be the golden standard in the diagnostics of gastroesophageal reflux disease (GERD). The technique allows for differentiation of gas and liquid reflux as well as detection of non-acid reflux, which cannot be detected with other techniques that are based only...

The added value of impedance-pH monitoring to Rome III criteria in distinguishing functional heartburn from non-erosive reflux disease

Edoardo Savarino, Elisa Marabotto, Patrizia Zentilin, Marzio Frazzoni, more

Digestive and Liver Disease > 2011 > 43 > 7 > 542-547

Functional heartburn is defined by Rome III criteria as an endoscopy-negative condition with normal oesophageal acid exposure time, negative symptom association to acid reflux and unsatisfactory response to proton pump inhibitors. These criteria underestimated the role of non-acid reflux.To assess the contribution of impedance-pH with symptom association probability (SAP) analysis in identifying endoscopy-negative...

Postoperative Impedance–pH Testing is Unreliable After Nissen Fundoplication With or Without Giant Hiatal Hernia Repair

Brittany N. Arnold, Christy M. Dunst, Angi B. Gill, Trudie A. Goers, more

Journal of Gastrointestinal Surgery > 2011 > 15 > 9 > 1506-1512

Introduction Combined 24-h multichannel intralumenal impedance–pH monitoring (MII-pH) is gaining popularity as a diagnostic tool for gastroesophageal reflux. Since the surgical reduction of hiatal hernias and creation of a fundoplication anatomically restores the gastroesophageal reflux barrier, one would assume that it effectively stops all reflux regardless of composition. Our aim is to evaluate...

Prospective Assessment of Patient Selection for Antireflux Surgery by Combined Multichannel Intraluminal Impedance pH Monitoring

Gianmattia del Genio, Salvatore Tolone, Federica del Genio, Rajesh Aggarwal, more

Journal of Gastrointestinal Surgery > 2008 > 12 > 9 > 1491-1496

Introduction Selecting gastroesophageal reflux disease (GERD) patients for surgery on the basis of standard 24-h pH monitoring may be challenging, particularly if this investigation does not correlate with clinical symptoms. Combined multichannel intraluminal impedance pH monitoring (MII-pH) is able to physically detect each episode of intraesophageal bolus movements, enabling identification of either...

Total fundoplication controls acid and nonacid reflux: evaluation by pre- and postoperative 24-h pH–multichannel intraluminal impedance

Surgical Endoscopy > 2008 > 22 > 11 > 2518-2523

Background Studies have demonstrated that Nissen fundoplication controls acid gastroesophageal reflux (GER). Combined 24-h pH and multichannel intraluminal impedance (MII-pH) allows detection of both acid and nonacid GER. Antireflux surgery is considered for any patient whose medical therapy is not efficient, particularly patients with nonacid gastroesophageal reflux disease (GERD). Nevertheless,...
