Gastrointestinal (GI) motility problems are common complications in critical care patients. GI problems contribute to an increased risk of morbidity and mortality. Toxic megacolon (TM) is a type of acquired megacolon categorized as a medical emergency and includes severe inflammation affecting all layers of the colon wall. The high incidence of GI complications in critically ill patients requires the critical care nurse to provide close monitoring of patients at risk and an acute awareness of the causation, signs and symptoms, and treatment of various GI motility disorders, including gastroparesis, ileus, and TM.

Hypermobility spectrum disorders (HSD) and hypermobility Ehlers-Danlos syndrome (hEDS) are frequently associated with gastrointestinal symptoms, although the underlying mechanisms remain unclear. This study aimed to compare antroduodenal motility in patients with and without HSD/hEDS. We included 239 patients (50 HSD/hEDS and 189 non-HSD/hEDS) with gastrointestinal symptoms undergoing antroduodenal manometry (ADM).

Background: Alpha-thalassemia X-linked intellectual disability (ATR-X) syndrome, is a rare genetic disorder, caused by mutations in the ATRX gene. Clinical manifestations include typical facial dysmorphisms, mild-to-severe intellectual disability, hypotonia, genital anomalies, significant gastrointestinal (GI) complications, such as abdominal distension, chronic constipation, feeding difficulties, gastroesophageal reflux, and mild-to-moderate anemia secondary to alpha-thalassemia.
Case Presentation: We report a patient with ATR-X syndrome suffering from gastrointestinal dysmotility and highlight the beneficial effects of pyridostigmine.

Background: Many patients diagnosed with gastro-oesophageal reflux disease (GERD) have persistent symptoms despite proton pump inhibitor (PPI) therapy.
Aims: The aim of this consensus is to provide evidence-based statements to guide clinicians caring for patients with refractory reflux-like symptoms (rRLS) or refractory GERD.
Methods: This consensus was developed by the International Working Group for the Classification of Oesophagitis.
