Menetrier's disease represents a low prevalence clinical entity, characterized by complexity in its diagnosis, particularly due to the need to exclude its potential association with gastric cancer. In this context, we present the clinical case of a 54-year-old male with nonspecific gastrointestinal symptoms and hypoalbuminemia. During the upper endoscopy procedure, a noticeable thickening of gastric folds was observed, associated with multiple polypoid lesions in the stomach, predominantly in the fundus and body. Since the patient did not show improvement in symptoms and given the inability to rule out gastric cancer, total gastrectomy was chosen as the treatment. Surgical specimen and histology confirmed the presence of Menetrier's disease.

An adequate approach to refractory gastroesophageal reflux disease (rGERD) is essential for achieving therapeutic success. From the precise definition of rGERD to the detailed characterization of its phenotypes, it will pave the way for the customization of optimal therapy for each patient. In this narrative literature review, the aim is to provide an updated synthesis of the utility of various diagnostic tools and explore the wide range of therapeutic options, both medical and invasive, available for this condition.

After bariatric surgery one of the most common complications is dysphagia. The etiology of this disease has not been fully elucidated but it is known that it may be due to structural changes due to surgery. This case describes a 65-year-old female with early and severe onset of dysphagia following laparoscopic sleeve gastrectomy. The patient's final diagnosis was postobesity surgery esophageal dysfunction and laparoscopic proximal gastrectomy with esophagojejunal Roux-en-Y anastomosis was performed. Physicians should be aware of this condition in order to offer early diagnosis and treatment.

Obesity has become a growing global epidemic, demanding effective solutions for its management. Bariatric-metabolic surgery is currently the best therapeutic option for patients with morbid obesity and associated comorbidities. This review article addresses the importance of endoscopy in the preoperative and postoperative evaluation, as well as in the detection and management of complications associated with bariatric surgery.

Latin America presents a high prevalence of Helicobacter pylori(Hp) infection. Between1996-2003, the prevalence in Santiago, Chile, was 70%; recent studies indicate a decreasein this infection. Updating the frequency of Hp is crucial due to its associated health impact.

Objective: Our objective was to describe the trend in Hp infection in patients undergoingambulatory esophagogastroduodenoscopy (EGD) in a Chilean population.

Materials and methods: A retrospective observational study was conducted on patients over 18 years old who attended a first EGD with a rapid urease test between 2010-2020. Time trendswere described through time series analysis. A Poisson model was constructed to estimatethe risk of infection, adjusted for age and gender.

Results: 11,355 patients were included[66.9% females; mean age 52 years; Hp 41.6%]. Male gender presented a higher frequencyof Hp infection [RR 1.13; (95% CI: 1.08-1.18)].Hp frequency infection decreased significantlyfrom 45.1% in 2010 to 29% in 2020, with a 36% lower probability of Hp infection in 2020 compared to 2010 [RR 0.64;(95% CI: 0.55-0.74)]. A progressive decline in Hp infectiontrend was projected, reaching values close to 25% by year 2025.

Conclusion: A significantreduction in Hpinfection was observed between 2010-2020. This decrease could be explained by the implementation of public health policies in the last decade associated with socio-sanitary changes.

Wilkie syndrome is a rare pathology that generates intestinal obstruction due to a decrease of the aortomesenteric angle compromising the third portion of the duodenum. We describe a case of an 18-year-old female patient, diagnosed with Wilkie syndrome, with clinical symptoms of intestinal obstruction and weight loss. The diagnosis was made with abdominal CT. Wilkie syndrome is a rare pathology, which becomes a diagnostic challenge because it presents a similar picture to other more common pathologies. We recommend that it should be suspected in the presence of duodenal obstruction.

Acute gastric variceal bleeding is a life-threatening condition that could be effectively treated with endoscopic cyanoacrylate injection diluted with lipiodol. The mixture acts as a tissue adhesive that polymerizes when in contact with blood in a gastric varix. This work reports a patient that presented to the emergency department with upper gastrointestinal bleeding due to acute variceal bleeding, who developed systemic embolization following cyanoacrylate injection therapy. This complication culminated in cerebral, splenic and renal infarctions with a fatal outcome. Systemic embolization is a very rare, but the most severe complication associated with endoscopic cyanoacrylate injection and should be considered in patients undergoing this treatment.

Objective: Determine the sensitivity and specificity of the ESBP for diagnosis in patients with intermediate risk of choledocholithiasis, referred to the specialized surgical Gastroenterology center of Unión de Cirujanos SAS - Oncologists of the West Zentria group - Manizales - Colombia between March 01, 2020 to January 31, 2022.

Materials and methods: Retrospective cross-sectional study in patients with intermediate risk for choledocholithiasis. The diagnostic performance of ESBP was calculated and confirmed with ERCP. Negative ESBPs were followed up by telephone.

Results: 752 cases with ESBP were analyzed, of which 43.2% (n=325) were positive and 56.8% (n=427) were negative. ERCP was performed in positive cases who accepted the procedure (n=317); 73.5% (n:233) were positive for choledocholithiasis, 25.8% (n=82) tumors and 0.6% (n=2) biliary roundworms. Patients with positive ESBP underwent ERCP. S= 98.3% (95% CI: 95.7-99.5) was obtained; E= 88.1% (95% CI: 79.2-94.1); PPV = 95.8% (95% CI: 92.4-98.0); NPV = 94.9% (95% CI: 87.4-98.7). The AUC of ESBP was 0.9319 (95% CI 0.8961-0.967).

Conclusion: In patients with intermediate risk for choledocholithiasis, ESBP is a useful diagnostic option in the study of pancreatic pathologies, extrahepatic biliary tree, and the identification of biliary microlithiasis; Therefore, it also allows us to complement it with a therapeutic intervention such as ERCP in a single time.

Introduction: Treatment of functional disorders of the anorectal unit should focus on the underlying cause. Biofeedback therapy is a functional retraining of the pelvic floor that has proven useful in the treatment of constipation associated with dyssynergia and in the management of fecal incontinence. This study describes the first experiences with this form of biofeedback therapy in Colombia.

Objective: Describe our experience with biofeedback therapy in the gastrointestinal neurophysiology unit.

Materials and methods: This historical cohort included patients with an indication for biofeedback therapy for constipation or fecal incontinence in the gastrointestinal neurophysiology unit during the data collection period. The response to therapy is described by comparing manometricfindings before and after 10 biofeedback sessions.

Results: 21 patients were included(71.4% women, the average age was 68, 9 with constipation and 12 with fecal incontinence.Among the patients with constipation there was a significant improvement in 71.4% of those who had rectal hyposensitivity and in 57.1% of those with dyssynergia. Biofeedback therapysignificantly increased the balloon expulsion rate (11.1 vs. 66.7%, p=0.02). In patients with fecal incontinence, there was improvement in 50% of those who had anal hypotonia and in 80% of those who had anal hyposensitivity.

Conclusions: This study demonstrates that biofeedback therapy has a favorable impact on a high number of patients with constipationand fecal incontinence; in our center, the response is similar to that of the world literature.
