Objective: To evaluate the therapeutic success of endoscopic therapy with N-butyl-2-cyanoacrylate and to determine the re- bleeding and mortality rates.

Materials And Methods: Prospective analytical observational study of 47 cases of patients with gastric varices who were treated with N-butyl-2-cyanoacrylate, using a 1: 1 mixture with lipiodol between 2013 and 2017 in a level III public hospital in Lima - Peru.

[Porphyria cutanea tarda as extrahepatic manifestation of chronic hepatitis C: a case report].

The present case is a 56 year old male who present hyperpigmented and hypopigmented scars in both hands, associated with the presence of milia cysts. It was studied the metabolism of porphyrins and skin biopsy of the lesions which were compatible with porphyria cutanea tarda. In the initial laboratory, elevated transaminases values were found and subsequently identified chronic infection of hepatitis C virus.

[Validation of the rapid urease test for the detection of Helicobacter pylori in a Peruvian hospital].

Objective: To validate a rapid urease test (RUT) in Cayetano Heredia Hospital (HCH) in Lima, Peru.

Materials And Methods: This is a prospective observational study that included 181 patients over 18 years old with dyspeptic symptoms. All of them underwent upper gastrointestinal endoscopy at the Department of Gastroenterology at HCH.

[Venous tromboembolism in a patient with Crohn disease with ileal stenosis].

Inflammatory bowel disease is associated with extraintestinal manifestations. Among these manifestations is the venous tromboembolism which presents a risk three times more than that presented in general population. We report the case of a 61-year-old male with a history of abdominal pain, chronic diarrhea and fever, with leukocytosis, and fecal samples containing leukocytes, partial ileal stenosis with multiple ulcers in the enteroscopy, with histologic findings compatible with Crohn's disease.

[Association between ulcerative colitis and primary esclerosing cholangitis].

Ulcerative Colitis (UC) is associated to Primary Sclerosing Cholangitis (PSC) in 80% of cases, and this association is more common than the one with Crohn’s disease. Nevertheless, the prevalence of PSC in patients with UC is only 2.9% in Latin America.

[Comparison between Glascow-Blatchford, Rockall and AIMS65 scores in patients with upper gastrointestinal bleeding in a hospital in Lima, Peru].

Objective: Identify the best score that predicts each variable outcome (mortality, rebleeding and need for transfusion for more than 2 red blood cells pack) in patients with upper gastrointestinal bleeding until 30 days of the event. Material y methods: Patients included were those over 18 years, who had upper gastrointestinal bleeding between January 2014 to June 2015 in a general hospital of third level. The data was analyzed by the area under the curve ROC (Receiver Operating Characteristic).

[AIMS65 score validation for upper gastrointestinal bleeding in the National Hospital Cayetano Heredia].

Objective: To validate the score AIMS65 in patients with upper gastrointestinal bleeding, in terms of mortality and rebleeding a 30-day event.

Material And Methods: Patients included were those with higher age to 18 years attending the Hospital Nacional Cayetano Heredia during the period May 2013 to December 2014, by upper gastrointestinal bleeding. Data were analyzed using ROC curve (Receiver Operating Characteristic) and the area was obtained under the curve (AUC) to properly qualify the score AIMS65.

[Validation of the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding in a third level general hospital].

Objective: To validate the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding, in terms of mortality and recurrent bleeding at 30 days follow-up.

Material And Methods: Patients older than 60 year-old, with non variceal upper gastrointestinal bleeding demonstrated by endoscopy, who were attended in a third level general hospital from June 2009 to June 2013, were included. Data was analyzed with the ROC (Receiver Operating Characteristic) curve.
