Special Issue Information

Dear colleagues,

Welcome to “Gastrointestinal Motility and Functional Gut Problems for the Practitioner”, a new series for Gastrointestinal Disorders.

The biggest deficiency in Gastroenterology training programs in the US and worldwide is the teaching and understanding of gastrointestinal motility to trainees and physicians.  The fact that many entities can remain undiagnosed after upper and lower endoscopies, imaging modalities such as CT, MRI and even endoscopic ultrasound is not appreciated by trainees and practicing physicians.  Upon entering practice, a great volume of functional bowel disease patients awaits our newly minted gastroenterologists in their waiting rooms.  This reminds them of how some of their mentors had emphasized the art of medicine in the same sentence as the management of functional bowel and GI Motility disorders; but more likely they are keenly aware how they strove to avoid the dreaded irritable bowel, functional dyspepsia and gastroparesis patients in their clinical encounters.

Well I bear good tidings.  This new series I am editing will bring “GI motility to the masses” and make functional bowel disorders attractive because YES! You out there looking after patients both in small towns and large cities will be able to recognize and diagnose these entities. More importantly, this series will teach you that they are immensely treatable. Patient satisfaction from your expertise will be immeasurable and your reputation as the consummate gastroenterology clinician and motility specialist will be appreciated and respected by your colleagues.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Gastrointestinal Disorders is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Introduction: Patients with symptoms (Sx) of gastrointestinal (GI) motor disorders have limitations in physical strength and mobility. We hypothesized that physical frailty correlated with severity of GI symptoms, and that a motility frailty index (MFI) could be constructed. Patients: We conducted a prospective pilot study on 40 patients, (38 F, 2 M, mean age 39.9 years) with the following diagnoses: 10 with diabetes mellitus and 30 with non-diabetic/idiopathic disorders. Upper and lower GI Sx were quantified using an FDA-compliant, traditional patient-reported outcomes (PRO) system. Methods: Patients underwent a series of physical performance measures involving standing balance (SB), usual walk speed (UW), and chair sit-and-stands (CS). A GI motility frailty index (MFI) was constructed by fitting several models with a combination of physical performance measures and correlating with PRO. Pearson’s correlation compared the constructed index with the GI Sx PRO to construct a GI MFI. Results: The studied patients collectively showed marked limitations in mobility compared with standard performance values with mean (sd) ratios of SB = 0.87 (0.20), UW = 0.45 (0.13), and CS = 0.38 (0.17). Correlations between physical mobility and GI Sx were noted for upper GI Sx (rho = 0.47, p = 0.002) but not for lower GI Sx. Conclusions: In this pilot study of patients with GI motility disorders, we found increased physical limitations on performance-based testing, which had a statistically significant positive correlation with severity of upper GI motor Sx using a standardized PRO system. A motility frailty index has been constructed that may serve as a basis for better quantifying limitations in patient mobility. Full article

Median arcuate ligament syndrome (MALS), otherwise called celiac artery compression syndrome (CACS), is an uncommon disorder that results from an anatomical compression of the celiac axis and/or celiac ganglion by the MAL. Patients typically present with abdominal pain of unknown etiology exacerbated by eating along with nausea, vomiting, and weight loss. MALS is a diagnosis of exclusion that should be considered in patients with severe upper abdominal pain, which does not correlate with the objective findings. The cardinal feature which is elicited in the diagnosis of MALS relies on imaging studies of the celiac artery, demonstrating narrowing during expiration. The definitive treatment is the median arcuate ligament’s surgical release to achieve surgical decompression of the celiac plexus by division of the MAL. This article describes our experience with this entity, focusing on symptom presentation, diagnostic challenges, and management, including long-term follow-up in four cases. Full article
