Review
Dilatation of the gut occurs in response to either mechanical obstruction or aperistalsis. The hallmark features are symptoms of bowel obstruction with vomiting, constipation, abdominal pain and distension. This review will primarily deal with the non-mechanical causes of gut dilatation, both intestinal and colonic, and differentiate between acute and chronic presentations.

Gastrointestinal syndromes preceding a diagnosis of Parkinson's disease: testing Braak's hypothesis using a nationwide database for comparison with Alzheimer's disease and cerebrovascular diseases.
OBJECTIVE
Braak's hypothesis states that Parkinson's disease (PD) originates in the gastrointestinal (GI) tract, and similar associations have been established for Alzheimer's disease (AD) and cerebrovascular diseases (CVD). We aimed to determine the incidence of GI syndromes and interventions preceding PD compared with negative controls (NCs), AD and CVD.
DESIGN
We performed a combined case-control and cohort study using TriNetX, a US based nationwide medical record network. Firstly, we compared subjects with new onset idiopathic PD with matched NCs and patients with contemporary diagnoses of AD and CVD, to investigate preceding GI syndromes, appendectomy and vagotomy. Secondly, we compared cohorts with these exposures to matched NCs for the development of PD, AD and CVD within 5 years.
RESULTS
We identified 24 624 PD patients in the case-control analysis and matched 18 cohorts with each exposure to their NCs. Gastroparesis, dysphagia, irritable bowel syndrome (IBS) without diarrhoea and constipation showed specific associations with PD (vs NCs, AD and CVD) in both the case-control (odds ratios (ORs) vs NCs 4.64, 3.58, 3.53 and 3.32, respectively, all p<0.0001) and cohort analyses (relative risks (RRs) vs NCs 2.43, 2.27, 1.17 and 2.38, respectively, all p<0.05). While functional dyspepsia, IBS with diarrhoea, diarrhoea and faecal incontinence were not PD specific, IBS with constipation and intestinal pseudo-obstruction showed PD specificity in the case-control (OR 4.11) and cohort analysis (RR 1.84), respectively. Appendectomy decreased the risk of PD in the cohort analysis (RR 0.48). Neither inflammatory bowel disease nor vagotomy were associated with PD.
CONCLUSION
Dysphagia, gastroparesis, IBS without diarrhoea and constipation might specifically predict Parkinson's disease.

Review
Gastrointestinal tract involvement in systemic sclerosis concerns more than 90% of patients but is of heterogeneous clinical expression. It can involve the entire intestinal tract and be responsible for multifactorial malnutrition, which is frequent in this disease. It is a major source of deterioration in the quality of life and can even be life-threatening. Management is complex and multidisciplinary, ranging from simple hygienic and dietary measures, to specialized endoscopic or surgical interventional procedures, also including medical treatments, particularly proton pump inhibitors and prokinetics, with potential side effects. Ongoing research for new diagnostic and therapeutic tools promises to improve the management and prognosis of these patients.

Review
Gastrointestinal complications after cardiac surgery are relatively rare entities but carry a high mortality. We identified over 70 articles written since 2010 using the PubMed database. We included 40 in our review. The most common complications include paralytic ileus, gastrointestinal bleeding, and bowel ischemia. Patients who undergo cardiac procedures are at risk for poor perfusion of the gastrointestinal tract and, thus, at risk for resulting complications. Risk factors for these complications include peri-operative use of vasopressors, prolonged operative time, and the time of cardiopulmonary bypass. Presentation of gastrointestinal complications tends to differ as patients after open heart surgery can remain intubated, and exams can be limited. Early recognition and aggressive therapy are paramount. We aim to provide a review that will help the reader get familiar with the most common gastrointestinal complications that can negatively affect outcomes after cardiac surgery.

Review
Large bowel obstruction is a serious event that occurs in approximately 25% of all intestinal obstructions. It is attributed to either benign, malignant, functional (pseudo-obstruction), or mechanical conditions. Benign etiologies of colonic obstructions include colon volvulus, anastomotic strictures, radiation injury, ischemia, inflammatory processes such as Crohn's disease, diverticulitis, bezoars, and intussusception.

Review
Visceral myopathy is a rare, life-threatening disease linked to identified genetic mutations in 60% of cases. Mostly due to the dearth of knowledge regarding its pathogenesis, effective treatments are lacking. The disease is most commonly diagnosed in children with recurrent or persistent disabling episodes of functional intestinal obstruction, which can be life threatening, often requiring long-term parenteral or specialized enteral nutritional support. Although these interventions are undisputedly life-saving as they allow affected individuals to avoid malnutrition and related complications, they also seriously compromise their quality of life and can carry the risk of sepsis and thrombosis. Animal models for visceral myopathy, which could be crucial for advancing the scientific knowledge of this condition, are scarce. Clearly, a collaborative network is needed to develop research plans to clarify genotype-phenotype correlations and unravel molecular mechanisms to provide targeted therapeutic strategies. This paper represents a summary report of the first 'European Forum on Visceral Myopathy'. This forum was attended by an international interdisciplinary working group that met to better understand visceral myopathy and foster interaction among scientists actively involved in the field and clinicians who specialize in care of people with visceral myopathy.

We present the case of a 72-year-old woman with a history of right radical mastectomy due to the Phyllodes Tumor. Two months later, she went to the emergency room for intestinal occlusion. Analytically, she had anemia and thrombocytopenia. The abdominal tomography noticed signs of occlusion of the small bowell and injury of 5cm at the pericaecal level. Urgent exploratory laparotomy was performed and objectified distal ileum attached to the cecum with signs of irreversible ischemia, so an ileocaecal resection was performed with ileo-colonic anastomosis. In the postoperative period she presented paralytic ileus and paraneoplastic syndrome with bicytopenia refractory to corticosteroid treatment. To rule out abdominal complications, abdominal tomography was performed on the 5th day post-op that confirmed the integrity of the anastomosis and absence of signs of mechanical occlusion. The patient's evolution was unfavorable, went on to exitus on the 14th day. The anatomopathological study diagnosed metastasis of malignant Phyllodes Tumor at the ileal level.

Review
Hirschsprung disease (HSCR) and its associated disorders (AD-HSCR) often result in severe hypoperistalsis caused by enteric neuropathy, mesenchymopathy, and myopathy. Notably, HSCR involving the small intestine, isolated hypoganglionosis, chronic idiopathic intestinal pseudo-obstruction, and megacystis-microcolon-intestinal hypoperistalsis syndrome carry a poor prognosis. Ultimately, small-bowel transplantation (SBTx) is necessary for refractory cases, but it is highly invasive and outcomes are less than optimal, despite advances in surgical techniques and management. Thus, regenerative therapy has come to light as a potential form of treatment involving regeneration of the enteric nervous system, mesenchyme, and smooth muscle in affected areas. We review the cutting-edge regenerative therapeutic approaches for managing HSCR and AD-HSCR, including the use of enteric nervous system progenitor cells, embryonic stem cells, induced pluripotent stem cells, and mesenchymal stem cells as cell sources, the recipient intestine's microenvironment, and transplantation methods. Perspectives on the future of these treatments are also discussed.
