Esophageal shortening after rapid drink test during esophageal high-resolution manometry: A relevant finding?

Background: Esophageal shortening (ES) might be observed during high-resolution manometry (HRM), in particular after the rapid drink test (RDT). We aimed to assess its diagnostic value in patients referred for HRM.

Methods: HRM of patients without previous esophagogastric surgery or endoscopic treatment was retrospectively reviewed using the Chicago Classification v3.

Anal Fistulas in Severe Perineal Crohn's Disease: Mri Assessment in the Determination of Long-Term Healing Rates.

Background & Aims: The European Crohn's and Colitis Organization recommends magnetic resonance imaging (MRI) of anal fistulas to decide on the drug/surgery strategy. No evidence is available on the long-term impact of MRI features on fistula healing. The aim of this study was to evaluate the benefit of combined drug/surgery strategies for the treatment of perianal Crohn's fistulas based on MRI factors at referral.

Anal sphincter function as assessed by 3D high definition anorectal manometry.

Purpose: High resolution anorectal manometry has been developed over the past years, as well as 3D high definition manometry (HDARM). However, the clinical impact of the results obtained with these new technologies remains to be determined. We thus analyzed various HDARM parameters of anal sphincter function and tested their capacity to discriminate between patients with constipation and those with fecal incontinence.

Anal ulcerations in Crohn's disease: Natural history in the era of biological therapy.

Background: The natural history of anal ulcerations in Crohn's disease remains unknown.

Aims: To assess the long-term outcomes of anorectal ulcerations.

Methods: Data from consecutive patients with perineal Crohn's disease were prospectively recorded.

Efficacy and Safety of Peroral Endoscopic Myotomy for Treatment of Achalasia After Failed Heller Myotomy.

Background & Aims: In patients with persistent symptoms after Heller myotomy (HM), treatment options include repeat HM, pneumatic dilation, or peroral endoscopic myotomy (POEM). We evaluated the efficacy and safety of POEM in patients with achalasia with prior HM vs without prior HM.

Methods: We conducted a retrospective cohort study of 180 patients with achalasia who underwent POEM at 13 tertiary centers worldwide, from December 2009 through September 2015.

Long-term outcomes of per-oral endoscopic myotomy in patients with achalasia with a minimum follow-up of 2 years: an international multicenter study.

Background And Aims: Per-oral endoscopic myotomy (POEM) has shown promising safety and efficacy in short-term studies. However, long-term follow-up data are very limited. The aims of this study were to assess (1) clinical outcome of patients with a minimum post-POEM follow-up of 2 years and (2) factors associated with long-term clinical failure after POEM.

High-resolution Impedance Manometry after Sleeve Gastrectomy: Increased Intragastric Pressure and Reflux are Frequent Events.

Introduction And Purpose: Sleeve gastrectomy (SG) is gaining ground in the field of bariatric surgery. Data are scarce on its impact on esophagogastric physiology. Our aim was to evaluate the impact of SG on esophagogastric motility with high-resolution impedance manometry (HRIM) and to assess the usefulness of HRIM in patients with upper gastrointestinal (GI) symptoms after SG.

Magnetic resonance imaging and clinical assessments for perianal Crohn's disease: gain and limits.

Background: Assessment of perianal Crohn's disease remains challenging. European Crohn's and Colitis Organisation (ECCO) recommend magnetic resonance imaging (MRI) as a gold standard, but both accuracy and advantages remain limited compared to systematic clinical assessment. The aim of this study was to define their actual diagnostic value.
