Carmen Elena Fuenmayor, Carlos Gainza, Maryori García, Richard Zambrano, Gledys Torres, Yohanys Hernández, Anna García
Pneumatosis cystoides intestinalis is a rare condition in which multiple gas-filled cysts are found within the wall of the gastrointestinal tract either in the subserosa or submucosa. Its pathogenesis is uncertain and several pathogenic mechanisms have been proposed to explain its origin. The case of a male patient of 46 years with previous diagnosis of pneumatosis cystic intestinalis, who consulted for abdominal pain, vomiting and fever (39 °C) is presented. By the time of admission ther were signs of peritoneal irritation...

REVIEW
Geoffrey Burnstock
Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling...

PURPOSE: To investigate the pattern of referral of patients with superior mesenteric artery embolism (SMAE) and its effect on outcomes, and to evaluate the risk factors for bowel infarction. MATERIALS AND METHODS: This retrospective study included 66 consecutive patients diagnosed with acute SMAE between January 2001 and June 2016. Appropriate diagnosis by the referring physician was defined if the referral letter indicated that acute mesenteric ischemia was suspected or had been diagnosed at the referral center...

Vitamin B12 deficiency is a common cause of megaloblastic anemia, various neuropsychiatric symptoms, and other clinical manifestations. Screening average-risk adults for vitamin B12 deficiency is not recommended. Screening may be warranted in patients with one or more risk factors, such as gastric or small intestine resections, inflammatory bowel disease, use of metformin for more than four months, use of proton pump inhibitors or histamine H2 blockers for more than 12 months, vegans or strict vegetarians, and adults older than 75 years...

REVIEW
Augusto Lauro, Ignazio R Marino, Kishore R Iyer
Pre-emptive transplantation is a well-established practice for certain types of end-organ failure such as in the use of kidney transplantation. For irreversible intestinal failure, total parenteral nutrition (TPN) remains the gold standard, due to the suboptimal long-term results of intestinal transplantation. As such, the only role for pre-emptive transplantation, if at all, will be for patients identified to be at high risk of complications and mortality while on definitive long-term TPN. In these patients, the timing of early listing and transplantation could become life-saving, taking into account that mortality on the waiting list is still the highest for intestinal candidates...

BACKGROUND: Gastrointestinal carcinoid tumours, despite their low malignant potential, frequently metastasize to the liver. While liver resection improves survival and provides symptomatic relief, multifocal bilobar disease complicates surgical management. METHOD: All patients with carcinoid liver secondaries managed by resection from 1990-2015 were identified from a prospective departmental database. Demographic data, operative management, morbidity using the Accordion classification and mortality were analysed...

A Vyas, G Goel
Diaphragmatic rupture is a common occurrence following a major chest trauma and is most commonly associated with road-traffic accidents. Here we report a case of delayed presentation of a 40-year-old man with a ruptured diaphragm with obstruction and bowel infarction, three and a half year following a blunt trauma to chest. This case illustrates how the diagnosis and aggressive management of ruptured diaphragm can be central to life saving and demonstrates the importance of early intervention in cases with features suggestive of compromise of bowel vascularity...

OBJECTIVE: The prognosis of acute superior mesenteric venous thrombosis (SMVT) remains obscure. We aimed to investigate the treatment outcomes and possible risk factors for bowel infarction in these patients. METHODS: We retrospectively included 66 patients with acute SMVT between January 2002 and June 2016. Each patient underwent contrast-enhanced computed tomography as part of the initial diagnosis. The standard protocol for management included a nonsurgical approach with early anticoagulation and selective exploration...

The number of permanent colostomies carried out in the United Kingdom is approximately 6400 per year1. Stomal prolapse is a known complication of colostomy formation. We presented the first case of small bowel herniation into a healthy stomal prolapse with subsequent ischaemia of the herniated bowel in a 102-year-old patient. This rare sequela of a relatively common stomal complication highlights an important consideration when faced with a large prolapse presenting acutely. It also raises an important discussion point for the management of our ever-ageing patient population...

The surgical evaluation of haemorrhagic infarcted intestine and the decision for or against bowel resection require a lot of experience and are subjective. The aim of this prospective, clinical study was to examine the correlation between oxygen saturation and small intestinal wall (IW) thickness, using two objective methods. In 22 colicky horses, the blood flow, oxygen saturation and relative amount of haemoglobin were measured intraoperatively via laser Doppler and white light spectroscopy (O2C, oxygen to see, LEA Medizintechnik) at six measuring points (MPs) in small and large intestines...

PURPOSE: Acute mesenteric ischemia (AMI) is a life-threatening disease that leads to bowel infarction and death. The optimal management of AMI remains controversial. The present meta-analysis aimed to estimate the prognostic impact of surgical (SG) versus endovascular or hybrid intervention (EV) as the first-line treatment for acute arterial occlusive mesenteric ischemia and to assess whether endovascular strategy was actually effective in reducing bowel resection. METHODS: MEDLINE, Scopus and the Cochrane Library databases were searched...

BACKGROUND & AIMS: Therapeutic anticoagulation is the standard treatment in patients with acute non-cirrhotic portal vein thrombosis (PVT). In critically ill patients, anticoagulation only may not suffice to achive rapid and stable recanalization. This study evaluates efficacy and safety of transjugular interventional therapy in acute non-cirrhotic PVT. METHODS: This retrospective study includes 17 consecutive patients with acute noncirrhotic, non-malignant PVT...

Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

Henoch-Schönlein purpura is the most common childhood vasculitis, but may also affect adults. This article reviews the literature since 2011 on advances in diagnosis, clinical disease manifestations, pathophysiology and treatment of Henoch-Schönlein purpura. The clinical manifestations are thought to arise from IgA depositions in blood vessel walls in the affected organs, mostly skin, gastrointestinal tract, joints and kidneys. Corticosteroids may be effective in rapid resolution of renal manifestations and treating joint and abdominal pain, but they are not proven effective for treating organ manifestations and complications, such as glomerulonephritis, bowel infarction or intussusception...

BACKGROUND: Feeding jejunostomy has increasingly become a standard adjunctive procedure during major esophago-gastric resections. They provide nutritional support during the post-operative period as required. However, significant early complications have been reported, most notably small bowel necrosis. Literature reports have been restricted to case reports or series. This study aims to determine the frequency of this complication in a cohort of patients undergoing esophago-gastric resection, and identify any difference in the risk of this complication between patients undergoing esophagectomy and gastrectomy...

BACKGROUND: An abdominal aortic aneurysm (AAA) (pathological enlargement of the aorta) is a condition that can occur as a person ages. It is most commonly seen in men older than 65 years of age. Progressive aneurysm enlargement can lead to rupture and massive internal bleeding, which is fatal unless timely repair can be achieved. Despite improvements in perioperative care, mortality remains high (approximately 50%) after conventional open surgical repair. Endovascular aneurysm repair (EVAR), a minimally invasive technique, has been shown to reduce early morbidity and mortality as compared to conventional open surgery for planned AAA repair...
