Project description:Wilkie's Syndrome is a very rare disease caused by reduction of aorto-mesenteric space with consequent duodenum compression. It can combine with left renal vein stenosis which, when symptomatic, is known as "Nutcracker Syndrome". We describe a clinical onset case with epigastric pain without vomiting in a normal weight patient. 28-year-old woman who came to our observation for intense epigastric pain after a weight loss of 14 kg in 4 months. Multidetector Computed Tomography and Ultrasound revealed gastric and duodenal overdistension with hydro-air levels, severe duodenum stenosis, and left renal vein compression. Wilkie's Syndrome is common in anorexic individuals suffering from recurrent postprandial vomiting, onset with severe epigastric pain, without vomiting, is quite unusual. High-calorie diet must be first therapeutic approach, in case of failure treatment of first choice should be endovascular stenting and, only in selected cases, surgical treatment should be used because it is very invasive and burdened with numerous complications. Failure to diagnose this disease can expose patients to serious health risks.

Project description:Background: Acute mesenteric ischaemia (AMI) is a surgical emergency which has an associated high mortality. The mainstay of active treatment includes early surgical intervention, with resection of non-viable bowel, and revascularisation of the ischaemic bowel where possible. Due to the physiological insult of AMI however, perioperative care often involves critical care and the use of vasoactive agents to optimise end organ perfusion. A number of these vasoactive agents are currently available with varied mechanism of action and effects on splanchnic blood flow. However, specific guidance on which is the optimal vasoactive drug to use in these settings is limited. This systematic review aimed to evaluate the current evidence comparing vasoactive drugs in AMI. Methods: A systematic search of Ovid Medline, Ovid Embase, Cochrane CENTRAL and the Cochrane Database of Systematic Review was performed on the 5th of November 2020 to identify randomised clinical trials comparing different vasoactive agents in AMI on outcomes including mortality. The search was performed through the Royal College of Surgeons of England (RCSEng) search support library. Results were analysed using the Rayyan platform, and independently screened by four investigators. Results: 614 distinct papers were identified. After screening, there were no randomised clinical trials meeting the inclusion criteria. Conclusions: This review identifies a gap in literature, and therefore recommends an investigation into current practice and clinician preference in relation to vasoactive agents in AMI. Multicentre randomised controlled trials comparing these medications on clinical outcomes will therefore be required to address this question.

Project description:The current study presents a mesenteric mesenchymal tumor case, with unusual features in diagnostic imaging and histology. A 16-year-old male was admitted to the hospital with abdominal pain. Computed tomography (CT) revealed an abdominal mass, 2 cm in diameter. The results of contrast-enhanced CT, magnetic resonance imaging and 18F-fluorodeoxyglucose positron emission tomography indicated no specific features suggestive of its histology. Two arteries branching from the superior mesenteric artery were observed feeding the hypervascular tumor. After endoscopic and other laboratory findings revealed no additional lesions, the lesion was diagnosed as a primary mesenteric tumor. As the possibility of malignancy and future bleeding from this tumor could not be ruled out, a resection of the tumor was performed. During the surgery, the tumor, which was well circumscribed and hypervascular, was located in the mesentery of the jejunum. The resected tumor did not exhibit typical histological characteristics, and was labeled as 'myxoid smooth muscle neoplasm of uncertain biologic potential'. At 2 years after surgery, the patient remained well without evidence of recurrence. As primary mesenteric tumors are rare, particularly in young patients, it is considered important that this type of unusual tumor be included in the differential diagnosis for mesenteric tumors.

Project description:BackgroundThe mesenteric artery calcium score (MACS) identifies patients with possible chronic mesenteric ischaemia (CMI) using standard computed tomography (CT) imaging. The MACS does not necessitate a dedicated computed tomography angiography (CTA) which is required for evaluation of mesenteric artery patency. This study aimed to test the use of a symptom and MACS based score chart to facilitate the selection of patients with a low probability of CMI, in whom further diagnostic workup can be omitted, and to validate the CTA-based score chart proposed by van Dijk et al. which guides treatment decisions in patients with suspected CMI.MethodsThis retrospective study included consecutive patients with suspected CMI. The Agatston definition was used to calculate the MACS. Multivariable logistic regression analysis was used to create a MACS score chart, which was applied in all patients to determine its discriminative ability. The score chart by van Dijk et al. was validated in this independent external patient series.ResultsHundred-ninety-two patients were included, of whom 49 had CMI. The MACS score chart composed of the variables weight loss, postprandial abdominal pain, history of cardiovascular disease, and MACS, showed an excellent discriminative ability (area under the curve [AUC] 0.87). CMI risks were 2.1% in the low-risk group (0-4 points) and 39.1% in the increased risk group (5-10 points); sensitivity (97.8%) and negative predictive value (NPV; 97.9%) were high. The CTA-based score chart by van Dijk et al. showed an excellent discriminative ability (AUC 0.89).ConclusionThe MACS score chart shows promise for early risk stratification of patients with suspected CMI based on a near-perfect NPV. It is complementary to the CTA-based score chart by van Dijk et al., which showed excellent external validity and is well suited to guide subsequent (invasive) treatment decisions in patients with suspected CMI.

Project description:To investigate CT findings in patients with pathologically proven mesenteric ischaemia post-cardiopulmonary bypass surgery and compare them with the control group of patients without ischaemia.68 patients were identified by a search of local surgical and pathological databases; these patients met the inclusion criteria of a laparotomy within 1 month of a procedure requiring cardiopulmonary bypass and a CT abdomen/pelvis within 1 week of the pathological diagnosis. Two radiologists independently reviewed the studies, evaluating 17 separate findings relating to the bowel, the vasculature or other structures; consensus was subsequently reached. The diagnostic value of CT findings was assessed using logistic regression.52 of 68 patients had pathologically proven ischaemia. Portal venous gas, mesenteric venous gas and small bowel faeces sign all had specificities of >0.94 for ischaemia but low sensitivity (<0.27). Differential mural enhancement had high sensitivity (0.92) but poor specificity (0.50). The combination of pneumatosis, bowel loop dilatation and differential mural enhancement predicted bowel ischaemia with a probability of 98%. The hardest signs to interpret based on poor interreader kappa agreement were bowel wall thinning, mesenteric stranding and differential mural enhancement.A combination of CT signs was predictive of ischaemic bowel; however, the more specific findings lacked sensitivity. If clinical suspicion is high for bowel ischaemia, prompt surgical intervention is warranted, regardless of CT findings.Arterial occlusion was uncommon and venous occlusion was not present, which is supportive of a predominantly non-occlusive aetiology for ischaemia in this patient group.

Project description:We report the case of a 15-year-old female patient suffering from progressive anorexia, weight loss and recurrent abdominal pain, initially diagnosed as anorexia nervosa. She eventually presented with severe malnutrition and acute bowel obstruction, revealing a mass of the transverse colon. A well-differentiated Lieberkühn adenocarcinoma was established by histology. The patient underwent transverse and right colectomy and was treated with adjuvant chemotherapy. Colorectal cancer (CRC) is predominantly a disease of older adults and is extremely rare in children and adolescents. Seldom suspected, it is more likely to be diagnosed at an advanced stage, with unfavourable tumour histology and poor outcome. Young patients diagnosed with CRC should receive genetic counselling regardless of their family history or tumour type. This reports' take-home message is that recurrent and persistent digestive symptoms in the young should alert physicians and lead to further investigations.

Project description:Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overview and repository of the current evidence and multidisciplinary expert agreement on pertinent issues regarding diagnosis and treatment, and provides guidance in the multidisciplinary field of chronic mesenteric ischaemia.

Project description:Background?Stent thrombosis is a serious and potentially life-threatening complication of percutaneous coronary intervention. It often presents dramatically, typically resulting in ST-elevation myocardial infarction which is associated with a high mortality rate. Premature discontinuation of antiplatelet therapy in the initial 30?days after stenting is arguably the most important predictor of stent thrombosis. In some cases, discontinuation of therapy is unintentional, such as in patients with short-bowel length or malabsorption syndromes.Case summary?A 70-year-old man presented to our hospital with stent thrombosis due to non-absorption of antiplatelet agents, 3?days after an elective percutaneous intervention to the right coronary artery. The patient, who had had a laparoscopic high anterior resection due to previous colorectal cancer, had noticed tablets passing whole into his colostomy bag. Repeat balloon angioplasty and stenting were performed and the patient received further antiplatelet therapy in a crushed form.Discussion?Drug absorption in the gastrointestinal tract is altered when a significant length of the gut has been resected. Reduced intestinal luminal transit time and insufficient contact time with intestinal mucosa leads to reduced bioavailability of drugs and increased risk of stent thrombosis. The aetiology of stent thrombosis can be investigated with intravascular imaging techniques and platelet function testing. Management includes using different drug formulations and doses and monitoring the outcomes of therapy. In some cases, it may also be appropriate to involve a gastroenterology team, preferably in the multidisciplinary environment of an intestinal rehabilitation centre.

Project description:BackgroundMyocardial infarction with non-obstructed coronary arteries (MINOCA) syndrome accounts for ∼6-8% of acute coronary syndrome presentations. Historically, MINOCA has been thought of as a benign condition, however, recent evidence suggests that some aetiologies of MINOCA such as cardiomyopathies are associated with significantly higher mortality than other causes such as myocarditis. Therefore, identifying the underlying cause of MINOCA is important in determining patient management and prognosis.Case summaryWe describe the case of a 58-year-old lady with an acute admission with MINOCA syndrome. Cardiac magnetic resonance (CMR) examination on Day 9 demonstrated hypertrophy of the apical segments of the left ventricle (LV), with diffuse mid-wall hyper-enhancement on late gadolinium enhancement (LGE) images. T2-weighted imaging was suggestive of active inflammation in the hypertrophied segments. A repeat CMR scan was performed 3 months later showed normalization of LV wall thickness, LGE and T2 values in the apical segments.DiscussionThis case report highlights the benefits of CMR with oedema-weighted imaging in the acute stages of MINOCA syndrome, as well as the importance of serial imaging in this patient cohort. While baseline imaging raised the possibility of apical hypertrophic cardiomyopathy, resolution of apical hypertrophy on follow-up CMR showed that the patient had acute myocarditis, specifically involving the apical segments.
