INTRODUCTION: Gastric cancer (GC) is the first cause of cancer-related death in Chile and 6th in Latin America and the Caribbean (LAC). Helicobacter pylori (H. pylori) is the main gastric carcinogen, and its treatment reduces GC incidence and mortality. Esophageal-gastro-duodenoscopy (EGD) allows for the detection of premalignant conditions and early-stage GC. Mass screening programs for H. pylori infection and screening for premalignant conditions and early-stage GC are not currently implemented in LAC...

Obesity is a multifactorial, chronic, progressive and recurrent disease considered a public health issue worldwide and an important determinant of disability and death. In Spain, its current prevalence in the adult population is about 24% and an estimated prevalence in 2035 of 37%. Obesity increases the probability of several diseases linked to higher mortality such as diabetes, cardiovascular disease, hyperlipidemia, arterial hypertension, non-alcoholic fatty liver disease, several types of cancer, or obstructive sleep apnea...

BACKGROUND: Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) is a novel endoscopic method to palliate malignant gastric outlet obstruction. We aimed to assess whether the use of EUS-GE with a double balloon occluder for malignant gastric outlet obstruction could reduce the need for reintervention within 6 months compared with conventional duodenal stenting. METHODS: The was an international, multicentre, randomised, controlled trial conducted at seven sites in Hong Kong, Belgium, Brazil, India, Italy, and Spain...

Post-colonoscopy colorectal cancer (PCCRC) is a tumor that appears after a normal colonoscopy before the established time for the endoscopic follow up. Its origin reflects the quality of the colonoscopy and the different tumoral biologics between the CRC and the CRCPC. Our aim is to describe the characteristics of the PCCRC in our region, to identify risk factors, to discriminate the potential causes according to the World Endoscopý Organization (WEO) and to determine its impact in the patient's survival...

OBJECTIVE: Coffee ground vomiting is a classical symptom of upper gastrointestinal bleeding. However, the clinical usefulness is limited, due to the low positive predictive value. Our goal is to determine if whether an urgent endoscopy does modify our therapeutic management with a real impact on survival. PATIENTS AND METHODS: It is a retrospective, observational and descriptive study. We selected all patients that underwent a gastroscopy in our center for coffee ground vomiting over the last 4 years (2017-2021)...

INTRODUCTION AND AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is a complex procedure. Clinical guidelines assess competence in ERCP through a defined number of procedures, but multiple factors are involved. Our aim was to analyze the morphology of the papilla of Vater as an independent factor in selective common bile duct cannulation during resident training. MATERIAL AND METHODS: Patients that underwent ERCP were studied consecutively. All ERCPs were begun by a resident in training...

BACKGROUND: The updated Sydney system biopsy protocol (USSBP) standardizes the sampling of gastric biopsies for the detection of preneoplastic conditions (e.g., gastric intestinal metaplasia [GIM]), but the real-world diagnostic yield is not well-described. AIM: To determine whether regular application of USSBP is associated with higher detection of chronic atrophic gastritis (CAG), GIM and autoimmune gastritis (AIG). METHODS: We performed a real-world retrospective study at an academic urban tertiary hospital in Chile...

BACKGROUND AND OBJECTIVE: The development of a high level of competence and technical proficiency is one of the main objectives of any neurosurgical training program. Due to many factors, this progressive skill development can be complex during the residency. Despite its high cost and infrastructure requirements, there is renewed interest regarding the role of anatomy labs. The study and dissection of the human cadaver has been the environment where many surgeons have developed the necessary skills for microneurosurgery...

OBJECTIVE: To characterize pediatric patients undergoing esophagogastroduodenoscopy (EGD) in a high-complexity hospital. PATIENTS AND METHOD: Retrospective study in patients under 14 years of age who underwent EGD at the Hospital San Vicente Fundación de Medellín, between January 2019 and June 2020. The following sociodemographic characteristics were evaluated: age, sex, type of health insurance, place of origin, service where the procedure was indicated, indications for endoscopy, type of care, purpose of the procedure, endoscopic findings, endoscopic intervention, complications associated with the procedure or anesthesia, and relevance of the procedure...

AIMS: The World Endoscopy Organization (WEO) recommends that endoscopy units implement a process to identify postcolonoscopy colorectal cancer (PCCRC). The aims of this study were to assess the 3-year PCCRC rate and to perform root-cause analyses and categorization in accordance with the WEO recommendations. PATIENTS AND METHODS: Cases of colorectal cancers (CRCs) in a tertiary care center were retrospectively included from January 2018 to December 2019. The 3-year and 4-year PCCRC rate were calculated...

Flexible endoscopy (FE) plays a major role in the diagnosis and treatment of gastrointestinal disease. Although its intraoperative use has spread over the years, its use by surgeons is still limited in our setting. FE training opportunities are different among many institutions, specialties, and countries. Intraoperative endoscopy (IOE) presents peculiarities that increase its complexity compared to standard FE. IOE has a positive impact on surgical results, due to increased safety and quality, as well as a reduction in the complications...

OBJECTIVE: to evaluate the association between results from drug-induced sleep endoscopy (DISE) and computed tomography with lateral cephalometry (CTLC) of the pharynx in obstructive sleep apnea (OSA) patients, regarding the same anatomic level, in order to understand if CTLC could replace DISE in selected patients. STUDY DESIGN: cross-sectional. SETTING: Tertiary hospital. METHODS: A total of 71 patients who attended the Sleep Medicine Consultation in the Otorhinolaryngology Department of Hospital CUF Tejo between 1...
