Portal hypertension (PHT) is defined as an increase in pressure at the level of the portal vein above 5 mmHg, the most common cause being liver cirrhosis. Among the presinusoidal intrahepatic causes of PHT with portal venular involvement, what was traditionally known as idiopathic non-cirrhotic portal hypertension (NCIH) is described, with the requirements of excluding those patients who did not present PHT, as well as those with the presence of liver cirrhosis and thrombosis. portal venous vein (PVT). Currently, the diagnostic criteria for this entity have been reconsidered, and its name, being known as porto-sinusoidal vascular disease (PSVD), also does not exclude patients with PHT or the presence of underlying liver disease. Liver biopsy continues to be the gold standard for diagnosis. The clinical manifestations are derived from PHT and the management is similar to the complications that occur in patients with liver cirrhosis. The case of a male patient is presented who presents with symptoms of digestive bleeding, with findings of esophageal varices in upper endoscopy in addition to a study of viral, autoimmune liver disease and negative deposits, with a conclusive liver biopsy of porto-sinusoidal vascular disease.

Introduction: Endoscopy plays a fundamental role in inflammatory bowel disease (IBD), and becomes essential in diagnosis, treatment monitoring, and detection and management of complications.

Materials and methods: The Pan American Crohn's and Colitis Organization (PANCCO) and the Inter-American Society of Endoscopy (SIED) appointed 22 Latin American experts in IBD to develop a consensus study using the modified Delphi method, based on the best available evidence. A working group of 22 members from 9 countries identified 15 topics and formulated 98 statements, who participated in 2 rounds of voting. It was defined as agreement of ≥80% of experts for each statement.

Results: After the voting of all the statements, 8 statements were obtained that did not reach 80% consensus among the participants, so the questions were reconsidered in the Coordinating Committee of the consensus with the participation of the expert reviewers of these questions and 7 final statements were voted again by all the experts in a second round and 1 was eliminated with consensus. After two rounds of voting, the experts reached consensus with literature review with the best available evidence, the most important issues were developed with scientific evidence supporting each of the statements around the topic of endoscopy in IBD.

Conclusions: Consensus statements were developed and based on the best available evidence about endoscopy in inflammatory bowel disease.

Introduction: The EndoFLIP (for its acronym in English: endoluminal functional luminal probe) is a system that measures in real time the compliance index of the gastroesophageal junction and secondary esophageal peristalsis, based on the principle of impedance planimetry. Although this technology is relatively new and its diagnostic usefulness is still being evaluated, its use in clinical practice is increasingly recognized, fundamentally in those patients where there is no conclusive manometric diagnosis of esophageal motor pathology, mainly esophagogastric junction outflow obstruction and achalasia.

Objective: The aim of the present study is to describe the experience with EndoFLIP at the San Ignacio University Hospital in Bogotá, Colombia.

Material and methods: Descriptive observational case series study, which included patients over 18 years of age who had undergone EndoFLIP at the San Ignacio University Hospital from 2021 to 2022, either in-hospital or outpatient, with a clear indication of performance of the study, previously discussed in the multidisciplinary Gastroenterology Board.

Results: A total of 27 patients with an average age of 55 years were included in the study, of which 20 were women (74%) and 7 men (26%). The most frequent indication of the study was an inconclusive diagnosis of outflow tract obstruction identified in high-resolution esophageal manometry according to Chicago 4.0 criteria (14 patients), followed by hypercontractile esophagus (4 patients) and ineffective esophageal motility (3 patients). When evaluating the contractile response, it was found that 9 patients with an inconclusive diagnosis of outflow tract obstruction had a normal response, 3 absent and one altered; and in the patients with an inconclusive diagnosis of achalasia, one of them had a borderline contractile response and two had no response. All patients with a previous diagnosis of absent contractility had an equally absent contractile response in EndoFLIP.

Conclusion: Endoluminal functional luminal imaging is a technique that evaluates biomechanical properties such as distensibility, volume, pressure and even diameters of sphincter regions such as the gastroesophageal junction, pylorus and anus. Its usefulness has been highlighted for several indications, the most important being manometrically inconclusive diagnoses of esophageal motor disorders such as achalasia and outflow tract obstruction, pathologies that have a significant impact on the quality of life of patients and whose diagnosis is essential to be able to provide the best treatment option.

Celiac disease (CD) is an autoimmune malabsorption syndrome that presents with intolerance to gluten (gliadin), a protein found in wheat. The most common symptoms are diarrhea, steatorrhea, weight loss, weakness, vitamin and mineral deficiency. The probability of developing complicated CD is relatively low, among its main manifestations we have refractory sprue, T-cell lymphoma and ulcerative jejunitis (UY) of which a few cases develop gastrointestinal bleeding. Furthermore, we present the case of a 51-year-old patient who developed intestinal hemorrhage due to complicated CD, where upper digestive video endoscopy (VEDA), video colonoscopy (VCC), capsule endoscopy (CE) and biopsy of the jejunum and ileum were performed confirming the diagnosis of CD along with ulcerative jejunoileitis.

Dengue is a common infectious disease in tropical areas such as Peru. This virus can cause underreported and potentially fatal complications such as acute liver failure. We report the case of a 7-year-old boy who presented with fever, headache, and abdominal pain. On ultrasound, we found hepatomegaly and labs severe thrombocytopenia and elevated transaminases. During hospitalization he was diagnosed with severe dengue and developed acute liver failure, kidney injury, and encephalopathy. Although intensive care management and assisted ventilation, he developed multiple organ dysfunctions with fluid refractoriness and capillary leak. Acute liver failure secondary to severe dengue is a rare complication with an unfavorable outcome.

Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder, characterized by changes of the intestinal habit associated with abdominal pain. This study analyzed factors associated with this pathology during the COVID-19 pandemic, and it was seen that the impact of IBS was higher in young women who had ongoing studies in the medical field.

Objectives: Determine the prevalence of IBS in medical students and explore the associated factors with the increase of its symptoms, through the use of digital tools.

Materials and methods: Descriptive observational study with exploration of associations, with non-probabilistic sampling, until reaching the minimum sample of 110 participants with a confidence interval of 95%, finally having a total sample of 131 students, distributed in 3 proportional and representative subgroups of the last 3 years of study of the medical career from a university from Lima, Peru. The inclusion criteria were students of both sexes and legal age, who gave their consent to participate and did not have risk factors for GI disease. Once the study was approved, the link of a validated virtual questionnaire was shared through the institutional email. To explore the associated factors, the Chi-square test was used with a statistical significance of p < 0.05.

Results: Responses were obtained from 195 students; 64 (32.82%) of them had at least one exclusion criteria, finally having a sample size of 131; 64 (48.85%) were women, and 52 (39.69%) were from 7th year. Using the Rome IV criteria, 23 participants were classified as having IBS, which indicates a prevalence of 17.56%, 14 (60.87%) of them were women and 10 (43.48%) were from the 7th year (last year of study of the medical career in Peru). It was observed that 1 in 3 students (32.06%) had chronic abdominal pain, and 1 in 2 (53.44%) reported having a history of Major Depression or Generalized Anxiety Disorder. Of the total, 51 (38.93%) had a history of having a positive COVID-19 test result. Regarding the associated factors, a significant association was only found between IBS and the diarrhea type, classified according to the Bristol Scale.

Conclusions: The prevalence of IBS in medical students was 17.56%, the highest compared with studies in the general population and in medical students using Rome IV criteria. Of the associated factors, the clinical presentation of diarrhea, according to the Bristol scale, was associated with IBS.

Hepatic hydrothorax is a transudative pleural effusion in patients with cirrhosis. A 56-year-old cirrhotic patient presented with dyspnea and desaturation; his chest images showed a right pleural effusion. Another 66-year-old woman with cirrhosis, developed during her hospitalization acute respiratory failure, and her chest X- ray showed left pleural effusion. Initially, both patients were prescribed a dietary sodium restriction and diuretics. Nevertheless, they didn't have a good response so a chest tube was placed, and an octreotide infusion partially reduced the volume of the pleural drainage allowing a pleurodesis. We report two cases of refractory hepatic hydrothorax with multiple treatments including octreotide and pleurodesis.

Objective: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB).

Materials and methods: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a random-effects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach.

Results: Eight full-text RCTs and two RCT abstracts were included (n=1513). We did not find differences in rebleeding (RR, 0.78; 95% CI, 0.53-1.14, moderate QoE), surgery (RR, 0.58; 95% CI, 0.29-1.15, moderate QoE), mortality (RR, 0.89; 95% CI, 0.46-1.71, moderate QoE) or NUBT (MD, -0.01 units; 95% CI, -0.3 to 0.28, low QoE) between second-look and single endoscopy. Sensitivity analyses had similar results to the main analyses.

Conclusions: Routine second-look endoscopy was not more efficacious than single endoscopy in patients with PUB.

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract whose etiology is unknown, which can transmurally affect any segment of the intestine and/or the perineal region. Worldwide, the incidence of inflammatory bowel disease has increased in recent decades, and the same upward trend can be seen in South America. At national level, there are no official data, however, the increase in the number of publications in the last 20 years confirms this upward trend. Crohn's disease is a forgotten disease and does not have implemented clinical guidelines based on evidence that contribute to clinicians in decision making. In this sense, the Peruvian Association for the Study of the Intestine considers the preparation of this document relevant and timely. clinical contextualized for Peru.

Malignant peripheral nerve sheath tumors are frequently associated with neurofibromatosis type 1. They are usually located in the extremities or in the axial area. Its visceral location is very rare and its hepatic origin is infrequent. They tend to be aggressive with a poor response to chemotherapy and radiotherapy, so surgical management is the best treatment option. We present the case of a young man with neurofibromatosis type 1, who presented with hemoperitoneum as a complication of a malignant tumor of the peripheral nerve sheath located in the liver.
