To determine actuarial survival, the Kaplan-Meier method and the log-rank test were used to compare 2 survival curves.Results: A total population of 82 patients was evaluated, of which 46 received adjuvant chemotherapy and 36 perioperative chemotherapy, with the most commonly used regimen being CAPOX and EOX/EOX, respectively. Clinical characteristics did not significantly influence overall survival and only the primary tumor (T) had a statistically significant association, with T4a being more frequent in the perioperative chemotherapy group than in the adjuvant modality group (80.6% vs 47.8%; p=0.002). When comparing both therapeutic modalities, it was evident that patients who received perioperative chemotherapy had a longer survival at 5 years (53.2%), however, this was not statistically significant (p=0.230).Conclusions: Perioperative chemotherapy presented greater survival compared to adjuvant chemotherapy at 12, 36 and 60 months; however, these differences were not statistically significant.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 2","pages":"139-146"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144838066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intestinal ultrasound (IUS) has become a well-established, non-invasive, accurate, and well-tolerated tool to evaluate IBD activity in real time-even during the same medical consultation. Available evidence supports its usefulness in accurately determining inflammatory activity and identifying associated complications. At the time of diagnosis and initiation of treatment, IUS has proven to be the ideal non-invasive study for close monitoring, assessing therapeutic response, and making early treatment adjustments. Multiple systematic reviews and meta-analyses have shown that its diagnostic accuracy is comparable to that of colonoscopy or magnetic resonance imaging. Additionally, IUS allows for therapeutic monitoring and prognosis assessment in a more accessible, non-invasive way, with greater patient adherence compared to other diagnostic modalities. This review article aims to analyze the optimal use of IUS and its current role in the management of patients with IBD.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 2","pages":"155-175"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144838065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vanek's polyp, a rare entity, is characterized by its inflammatory infiltrate and vascular alterations, often leading to confusion with adenomatous lesions. We present the case of a 77-year-old woman with a one-month history of rectal bleeding, requiring hospitalization during one of the episodes. Colonoscopy revealed a pedunculated polyp, which was resected without complications. Histopathological analysis showed a lymphoplasmacytic infiltrate, multiple vessels with fibrinoid necrosis, and no neoplastic atypia. Due to the nonspecific nature of the report, immunohistochemical studies were performed, revealing CD34 positivity in the vessels and vimentin positivity in mesenchymal cells. These findings suggest a differential diagnosis from inflammatory fibroid polyps. Vanek's polyps are uncommon lesions that require accurate diagnosis and appropriate management. Recent trends show an increase in the identification of these polyps, likely due to advancements in diagnostic techniques.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 2","pages":"184-187"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144838068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This characteristic could be the reason why most duodenal diverticula appear in the juxtapapillary region, even including the papilla inside.Objective: The objective of the research was to determine the patients diagnosed with juxtapapillary diverticulum (JD) after endoscopic retrograde cholangiopancreatography (ERCP), who were confused with different previous diagnoses.Materials and methods: Retrospective study with intentional sample, where ERCP was performed on a universe of 12,686 patients who were referred with different previous gastrointestinal pathologies, therefore, they required diagnosis or treatment with this procedure.Results: Of the 12,686 patients who underwent ERCP, between 01/07/2014 and 28/06/2024, a total of 872 (6.9%) presented a confirmatory diagnosis of juxtapapillary diverticulum, a diagnosis that differed partially or totally from the one presented before the procedure.Conclusions: The prevalence detected was one of the highest reported for Latin America. DY is generally asymptomatic, affecting mostly elderly patients, but when it is symptomatic, they present different signs and symptoms, which simulate a wide variety of diagnoses, where the clinical and previous imaging studies do not provide sufficient clues for a correct analysis, therefore, ERCP is the perfect tool for the timely diagnosis and treatment of DY, clearing previous diagnostic doubts.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 2","pages":"147-154"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144838062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case of \"kissing ulcers\" diagnosed through esophagogastroduodenoscopy in a young woman undergoing doxycycline treatment for rosacea. The pathogenesis is linked to drug-specific factors, such as caustic effects, hyperosmolar properties, and prolonged mucosal contact with the medication, in addition to patient-specific risks, including esophageal motility disorders, reduced saliva production, and mid-esophageal anatomical compression. Clinically, patients commonly present with abrupt-onset chest pain, dysphagia, and odynophagia, while endoscopic findings often reveal mucosal erythema, erosions, and specular distribution esophageal ulcers (referred to as \"kissing ulcers\"). Management involves discontinuation of the causative drug, initiation of proton pump inhibitors or sucralfate, and implementation of preventive measures, such as ensuring adequate hydration during medication intake. This condition is generally self-limiting, with symptoms resolving within two weeks, underscoring the importance of prompt diagnosis and treatment to avoid potential complications.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 1","pages":"56-59"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144081069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
