Review
Small intestinal bacterial overgrowth (SIBO) is defined as an increase in the bacterial content of the small intestine above normal values. The presence of SIBO is detected in 33.8% of patients with gastroenterological complaints who underwent a breath test, and is significantly associated with smoking, bloating, abdominal pain, and anemia. Proton pump inhibitor therapy is a significant risk factor for SIBO. The risk of SIBO increases with age and does not depend on gender or race. SIBO complicates the course of a number of diseases and may be of pathogenetic significance in the development of their symptoms. SIBO is significantly associated with functional dyspepsia, irritable bowel syndrome, functional abdominal bloating, functional constipation, functional diarrhea, short bowel syndrome, chronic intestinal pseudo-obstruction, lactase deficiency, diverticular and celiac diseases, ulcerative colitis, Crohn's disease, cirrhosis, metabolic-associated fatty liver disease (MAFLD), primary biliary cholangitis, gastroparesis, pancreatitis, cystic fibrosis, gallstone disease, diabetes, hypothyroidism, hyperlipidemia, acromegaly, multiple sclerosis, autism, Parkinson's disease, systemic sclerosis, spondylarthropathy, fibromyalgia, asthma, heart failure, and other diseases. The development of SIBO is often associated with a slowdown in orocecal transit time that decreases the normal clearance of bacteria from the small intestine. The slowdown of this transit may be due to motor dysfunction of the intestine in diseases of the gut, autonomic diabetic polyneuropathy, and portal hypertension, or a decrease in the motor-stimulating influence of thyroid hormones. In a number of diseases, including cirrhosis, MAFLD, diabetes, and pancreatitis, an association was found between disease severity and the presence of SIBO. Further work on the effect of SIBO eradication on the condition and prognosis of patients with various diseases is required.

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.

Duodenal ulcer perforation, a frequent surgical emergency, needs simple closure with indirect Graham's Omentopexy which is effective with excellent results in majority of cases despite patients' late presentation. The objective of the study was to determine the frequency of postoperative complications of perforated duodenal ulcer, conducted in the Surgery Department, Jinnah Postgraduate Medical Centre, Karachi, from March 20, 2018 to September 20, 2018. The study was a descriptive case series of 108 patients of both genders with perforated duodenal ulcer > 1 week old with ASA score I & II. Patients with trauma and comorbidities were excluded. The patients underwent laparotomy and peritoneal toilet, and after noting the site of perforation indirect Graham's Omentopexy was performed. Complications like duodenal fistula, peritonitis, and paralytic ileus, and patient's death within 10 days of surgery were noted. Age ranged from 18 to 50 years with mean age of 35.027±5.13 years, mean weight 71.120±12.77 kg, mean height 1.541 ±0.09 metres, mean BMI 29.975±4.99 kg/m2, and the mean duration of complaint was 4.194±1.30 weeks. Male predominance in 75 (69.4%) patients. Duodenal fistula was seen in 10 (9.3%) patients, peritonitis 12 (11.1%), paralytic ileus 14 (13%) and mortality was in 11 (10.2%) patients.

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.

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.

Critical illness may disrupt nutritional, protective, immune, and endocrine functions of the gastrointestinal tract, leading to a state of gastrointestinal dysmotility. We aimed to identify factors associated with the occurrence of gastrointestinal dysmotility in critically ill patients. A cross-sectional retrospective study was conducted, using patient files as a source of data. The study included 185 critically ill patients treated in the intensive care unit of the University Clinical Center, Kragujevac, Serbia, from January 1, 2016, to January 1, 2022. Significant risk factors associated with some form of gastrointestinal dysmotility were acute kidney injury (with paralytic ileus, nausea, vomiting, and constipation), recent abdominal surgery (with ileus, nausea, vomiting, and constipation), mechanical ventilation (with ileus, and nausea), age (with ileus and constipation), and use of certain medication such as opioids (with ileus, gastro-esophageal reflux, nausea, vomiting, and constipation), antidepressants (with ileus, nausea, and vomiting), and antidiabetics (with ileus). On the other hand, Charlson comorbidity index had divergent effects, depending on the form of gastrointestinal dysmotility: it increased the risk of gastro-esophageal reflux but protected against ileus, nausea, and vomiting. In clonclusion, recognition of factors associated with gastrointestinal dysmotility should initiate preventative measures and, thus, accelerate the recovery of critically ill.

Digestion and intestinal absorption allow the body to sustain itself and are the emblematic functions of the bowel. On the flip side, functions also arise from its role as an interface with the environment. Indeed, the gut houses microorganisms, collectively known as the gut microbiota, which interact with the host, and is the site of complex immune activities. Its role in human pathology is complex and scientific evidence is progressively elucidating the functions of the gut, especially regarding the pathogenesis of chronic intestinal diseases and inflammatory conditions affecting various organs and systems. This editorial aims to highlight and relate the factors involved in the pathogenesis of intestinal and systemic inflammation.
