Fecal immunochemical test for hemoglobin versus fecal calprotectin to monitor endoscopic activity in inflammatory bowel disease.

Aim: endoscopy identifies inflammatory activity, however, it is an unpleasant test and is not always accessible. The aim of the study was to compare the usefulness of quantitative fecal immunochemical test (FIT) versus fecal calprotectin (FC) to determine endoscopic activity in patients with inflammatory bowel disease (IBD).

Methods: cross-sectional prospective observational study.

Treatment of abdominal fistulas in Crohn's disease and monitoring with abdominal ultrasonography.

Objective: to assess the usefulness of medical treatment to achieve closure of internal fistulas detected on abdominal ultrasound in a series of patients with fistulizing Crohn's disease.

Material And Methods: a retrospective analysis was performed of the medical records of patients with Crohn's disease with a fistula detected on abdominal ultrasound from 2010 to 2018. The study included patients who received medical treatment after the diagnosis of this complication and underwent ultrasonographic monitoring of the therapeutic response.
