[Gallstone ileus as a cause of mechanical intestinal obstruction: a case report].

Biliary ileus is a mechanical intestinal obstruction characterized by symptoms such as abdominal pain, jaundice and fever. The treatment of choice in these cases is associated with a surgical approach according to the clinical condition of the patient. It is important to study this pathology since its timely diagnosis and treatment are essential to avoid serious complications associated with high morbidity and mortality.

[Faecal microbiota study reveals specific dysbiosis in spondyloarthritis according to subtype, disease activity and treatment].

Colombian experience with the use of tofacitinib in severe acute ulcerative colitis: A case series study.

Introduction: Tofacitinib is indicated in patients with moderate to severe ulcerative colitis (UC); however, given its rapid onset of action, it may constitute an alternative in patients with hospitalized severe acute UC. There are few data on this indication in the literature. The aim of this study was to describe the efficacy and safety of tofacitinib in the management of patients with hospitalized UC, as well as its clinical characteristics and other treatment patterns.

[Health-related quality of life by IBDQ-32 in colombian patients with inflammatory bowel disease in remission: A cross-sectional study].

In Colombia there are no data about perception of quality of life (QoL) in inflammatory bowel disease (IBD). The aim of this study was to determine the perception of QoL by means of the IBDQ-32 questionnaire in patients with IBD from a sample of patients from different referral centers. We carried out a cross-sectional study in adults with IBD in clinical remission, in outpatient follow-up, in 3 institutions in different cities, between June 2022 and November 2022, eligible subjects were identified, information was collected on different dates, about socio-demographic and clinical aspects, and the IBDQ-32 questionnaire was evaluated on one occasion.

Colonoscopy aspiration lavages for mucosal metataxonomic profiling of spondylarthritis-associated gastrointestinal tract alterations.

The study of the GI-tract microbiota of spondylarthritis (SpA) patients has focused on the analysis of feces samples, that picture mostly the luminal microbiota. The aim of this study was to determine the contribution of mucosal and luminal microbiome to the gut dysbiosis in SpA, using colonoscopy aspiration lavages (CAL), a recent alternative for regional studies of the GI-tract. We analyzed 59 CAL (from sigmoid colon and distal ileum), and 41 feces samples, from 32 SpA patients and 7 healthy individuals, using 16S rRNA gene-targeted metataxonomic profiling.

[Experience with digital peroral cholangioscopy using SpyGlass DS in different reference centers in gastroenterology and digestive endoscopy in Colombia: Case series].

SpyGlass DS is a peroral cholangioscopy system, associated with improved image quality and configuration. Currently, there is diversity in its use and little information on its implementation, including clinical outcomes and adverse events. To describe the experience of using SpyGlass DS in several gastroenterology reference centres in Colombia, mentioning efficacy and possible adverse events.

Clinical and therapeutic characterisation of a multicentre cohort of patients with inflammatory bowel disease in Colombia.

Introduction: In Latin America and Colombia there are few studies about the clinical and therapeutic characteristics of patients with inflammatory bowel disease (IBD). The objective of this study is to obtain an approximation to these data from a sample of patients from different reference centres in Colombia.

Patients And Methods: Cross-sectional study in adult and paediatric patients, with IBD, attended ambulatory in 6 institutions in different cities, between 2017 and 2020 information was collected on different dates, about demographic, clinical, and therapeutic aspects.

P062 Chromoendoscopy With Magnification Colonoscopy: Analysis of Mucosa of Colon And Ileum In Patients With Gastrointestinal Symptoms Without IBD.

Background: Digital chromoendoscopy (Narrow Band Imaging By Olympus) or BLI (Blue Light Imaging By Fujifilm), with the magnification endoscope, allows a detailed evaluation of the mucosal surface and its vascular network, which facilitates the diagnosis and monitoring of early lesions. This technique has demonstrated a better detection, which allows optical diagnosis during a colonoscopy examination. Patients with SpA with nonspecific gastrointestinal symptoms, subclinical intestinal inflammation are defined as endoscopic and histologically.

[Endoscopic dilatation in a patient with achalasia during pregnancy: case report and review of the literature].

Achalasia in pregnancy is an infrequent, poorly understood condition and its treatment is not clearly defined. The repercussions on the patients nutritional status are serious and in a pregnant woman have serious implications for the course of gestation, with high risk of intrauterine growth restriction, preterm delivery and even fetal loss; there are symptoms that can be confused with hyperemesis gravidarum delaying the diagnosis. The therapeutic options are medical treatment, endoscopic and surgical interventions; to decide what is the best treatment, we should be taken into account the severity, gestational age and patient conditions.
