Vanek jejunal tumor, a rare cause of anemic syndrome. Review of the literature.

Inflammatory fibroid polyps (IPF), also called Vanek tumors, are rare, benign lesions of mesenchymal origin. They can affect both sexes with a majority incidence between 50-70 years.¹² We present the case of a 53-year-old woman with an outpatient clinic due to severe iron deficiency anemia, gastroscopy and colonoscopy without relevant findings.

Assessing inter- and intra-rater agreement of four upper digestive endoscopy visibility scores.

Although various upper digestive endoscopy visibility scores are available, no comparative studies have directly evaluated them to determine the most effective tool. A prospective study was conducted to evaluate the inter- and intra-rater agreement of four upper digestive endoscopy visibility scores. A dataset of 32 videos was randomly selected from a collection of complete endoscopy procedures.

Acute hepatitis secondary to febuxostat.

Febuxostat is a drug from the group of xanthine dehydrogenase inhibitors and is used in the treatment of hyperuricemia and gouty arthritis. However, it is not free of adverse effects, including alteration of liver profile tests. This is why we must pay attention to this type of adverse events in case it is necessary to suspend treatment.

Biliary obstruction secondary to duodenal follicular lymphoma with papillary involvement.

Duodenal-type follicular lymphoma is a clinical variant of follicular lymphoma located in the intestine, presenting as multiple small polyps. The estimated frequency is 1/7000 people and extraduodenal involvement is rare. It predominantly affects middle-aged women, although some cases of young patients have been published in the literature.

Low risk of new dysplastic lesions in an inflammatory bowel disease population study with dye chromoendoscopy.

Rates of new dysplastic lesions or cancer progression after first dye chromoendoscopy in the era of high-definition endoscopy have yet to be determined.  A multicenter, population-based, retrospective cohort study was performed in seven hospitals in Spain. Patients with inflammatory bowel disease and fully resected (R0) dysplastic colon lesions under surveillance with high-definition dye-based chromoendoscopy were sequentially enrolled between February 2011 and June 2017, with a minimum endoscopic follow-up of 36 months.

Endoscopic ultrasound-guided resolution of right hydronephrosis secondary to local compression by an inflammatory pancreatic mass.

We present the case of 67 years-old man with unremarkable medical history. He was admitted to our department for abdominal pain compatible with choledocholithiasis associated with acute cholecystitis. ERCP was performed but direct papillary canulation attempts failed by means of conventional sphincterotome.

Nakamura polyp, an extraordinarily rare finding.

The inflammatory myoglandular or Nakamura polyp is a very rare polyp, with about 100 cases having been described in the literature. It has specific endoscopic and histological characteristics, making its knowledge of it very important for its proper diagnosis. Its differential diagnosis with other types of polyps is of vital importance, both histologically and with respect to its endoscopic follow-up.

Endoscopic ultrasound guided diagnosis of a retroperitoneal extra-gastrointestinal stromal tumor.

GIST tumors are mesenchymal tumors that are usually positive for the CD-117 marker. They present mostly at middle ages of life and although the most frequent locations are the stomach, small intestine and rectum/colon, they can appear in unusual places such as the retroperitoneum. The case that we present reflects the diagnostic process with imaging tests such as echo-endoscopy with puncture, of a retroperitoneal GIST tumor.

Postreperfusion Biopsy as a Predictor of Biliary Complication After Deceased Donor Liver Transplantation. A Retrospective Cohort Study.

Background: Ischemia reperfusion injury (IRI) on postreperfusion biopsies is associated with worse outcomes after liver transplantation, although the influence on biliary complications (BC) remains poorly studied. Therefore, the primary aim of our study was to assess the influence of IRI on the incidence of BC. A secondary aim was to assess the influence of steatosis on biliary complications and determine factors that predictor BC.

Postreperfusion Liver Biopsy as Predictor of Early Graft Dysfunction and Survival After Orthotopic Liver Transplantation.

Background: Postreperfusion liver biopsy (PRB) can assess the degree of ischemia/reperfusion injury (IRI) after orthotopic liver transplantation (OLT). The influence of IRI on graft outcomes and overall survival is controversial.

Aim: To determine the correlation between the severity of IRI in PRB and overall graft and patient survival and, secondarily, to identify factors on PRB that predict poor graft outcomes.

Esophageal hyperkeratosis as an uncommon manifestation of gastroesophageal reflux disease.

We present the case of a 66-year-old woman with intermittent dysphagia and esophageal food impaction. The endoscopic examination showed an upper and middle esophagus with a diffuse circumferential, white, crackleware epithelium. Esophageal biopsies revealed acanthosis and papillomatosis with diffuse hyperkeratosis.

Immunosuppressive Treatment With mTOR Inhibitors for Malignancies After Liver Transplantation: Long-Term Survival Retrospective Analysis.

Background: Immunosuppressive calcineurin inhibitors have been associated with an increased risk of post-transplant malignancies. The mammalian target of rapamycin inhibitors (mTORi) is an alternative immunosuppressive regimen with an antineoplastic effect. The aim of the study was to determine the long-term survival of mTORi-treated recipients with de novo or recurring tumors after liver transplantation (LT).

Hemophagocytic Syndrome as Uncommon Cause of Severe Pancytopenia After Liver Transplantation.

A rare but life-threatening cause of pancytopenia after liver transplantation is hemophagocytic syndrome. We present a 48-year-old woman who underwent liver transplantation and developed a hemophagocytic syndrome secondary to Epstein-Barr virus with a fatal course, despite initial treatment with immunosuppressants. The diagnosis was made based on the bone marrow aspiration, in which macrophages with phagocytic activity were observed, and clinical findings.

Using the internet to evaluate the opinion of patients with inflammatory bowel disease with regard to the available information.

Background And Aims: patients need information for shared decision making. The aims of the study were to ascertain how patients with inflammatory bowel disease (IBD) felt about the information available and the way that their doctors informed them. In addition, how patients used the internet and factors that predicted a positive information evaluation were also assessed.
