Introduction and Aims: Capsule endoscopy is part of the diagnostic approach to patients with suspected small bowel bleeding and data on its clinical impact are still limited in developing countries. The primary aim of the present study was to determine its impact on subsequent diagnostic and therapeutic decisions., Material and Methods: A retrospective study was conducted that included all the patients that underwent capsule endoscopy with the PillCam™ SB 3 Capsule system due to suspected small bowel bleeding treated at the Hospital Universitario Fundación Valle del Lili between January 2011 and December 2020., Results: A total of 158 patients met the inclusion criteria. Mean patient age was 63 years (interquartile range [IQR], 52-74), 53.6% of the patients were women, and high blood pressure was the most frequent comorbidity (43.7%). The main indication was overt bleeding (58.2%). Of all the capsule endoscopies carried out, 63.9% showed lesions that were potentially responsible for bleeding. Medical or surgical treatment was indicated in 63.3% of the case total. Rebleeding at 6 months occurred in 15 patients and there were 2 deaths due to gastrointestinal bleeding at 6 months., Conclusions: Capsule endoscopy has a high impact on patients with suspected small bowel bleeding, with respect to clinical decision-making, as well as rebleeding, hospitalization, and mortality outcomes. The positivity rate of lesions potentially responsible for bleeding was similar to that reported in developed countries., (Copyright © 2023 Asociación Mexicana de Gastroenterología.

An observation study, which analyzed cases and controls, was realized with 1850 adults subjected to upper digestive endoscopy, who were sent to the Endocentro Ltda. Medical center in Bogota, Colombia, due to diverse symptoms, and who had not received previous treatment with antibiotics, antibacterial medication or medication that altered gastric secretion. Chronic follicular gastritis was found in 8.4% (102 patients), 73 women and 29 men, with an average age of 33.5 years. Inflammation activity was detected in 99% and H. pylori in 98% of the patients. The controlled group was made up of 1100 patients with other kinds of chronic gastritis different from follicular gastritis. With these 1100 patients, 698 women and 412 men, with an average age of 48.3 years, inflammatory activity was found in 72.1% and H. pylori in 63.3%. In the feminine gender, a minimum risk increase was determined, without presenting changes in chronic follicular gastritis of statistical significance OR = 1.48 (95% IC 0.93-2.41). In the young patients who were less than 35 years old and in those infected by H. pylori, a higher risk for follicular gastritis changes was observed OR = 7.57 (95% IC 4.82-11,97) and OR =28.94 (95% IC 7.72-243.23) respectively. A greater inflammatory activity was observed in patients with chronic follicular gastritis, OR = 38.96 (95% IC 6.76-1558.64). [ABSTRACT FROM AUTHOR]

Introduction: The small bowel capsule endoscopy (SBCE) has revolutionised the study of small bowel diseases. The objective of this study is to determine the indications, findings and diagnostic yield of SBCE in a national registry., Patients and Methods: An observational, analytical cross-sectional study was carried out, analysing the SBCE records at seven centres in the country, where different variables were collected., Results: 1,883 SBCEs were evaluated. The average age was 55.4 years (5.6-94.2). The most frequent indications were suspicion of small bowel bleeding (SBB) (64.4%), study of Crohn's disease (15.2%) and chronic diarrhoea (11.2%). 54.3% were prepared with laxatives. The most frequent lesions found were erosions/ulcers (31.6%), angioectasias (25.7%) and parasitosis (2.7%). The diagnostic yield (P1+P2, Saurin classification) of SBCE in SBB was 60.6%, being higher in overt SBB (66.0%) compared to occult SBB (56.0%) (P=.003). The studies with better preparation showed higher detection of lesions (93.8% vs. 89.4%) (OR=1.8, CI: 95%: 1.2-2.6; P=.004). The SBCE complication rate was 3.1%, with complete SB visualisation at 96.6% and SB retention rate of 0.7%. 81.5% of SBCEs were performed on an outpatient basis, and presented a greater complete SB visualisation than hospital ones (97.1% vs. 94.3%) (OR=2.1, CI: 95%, 1.2-3.5; P=.008)., Conclusions: The indications, findings and diagnostic performance of SBCEs in Colombia are similar to those reported in the literature, with a high percentage of complete studies and a low rate of complications., (Copyright © 2020 Elsevier España, S.L.U.
