It is associated with infectious, neoplastic, traumatic processes, or foreign bodies. We report a case of DCF secondary to the migration of a metallic wire from the duodenum to the inferior vena cava (IVC), accompanied by extensive venous thrombosis. A 48-year-old male with no relevant medical history presented with fever and nonspecific abdominal pain. He was admitted with an initial diagnosis of acute dengue in the context of an ongoing epidemic. Computed tomography revealed a linear metallic foreign body crossing the second portion of the duodenum, penetrating the visceral wall, and lodging within the lumen of the IVC, with air inside and extensive venous thrombosis. Upper digestive video endoscopy (EGD) was performed, with successful extraction of the foreign body. The patient received intravenous antibiotic therapy for 10 days and oral anticoagulation for 6 months. Clinical evolution was favorable, and the patient recovered without complications. DCF due to a foreign body is extremely rare. Endoscopic management can be successful in selected cases, avoiding invasive surgical procedures.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 4","pages":"419-421"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145967164","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}

Endoscopic resection of colorectal polyps has been shown to reduce the incidence and mortality of CRC. Underwater endoscopic mucosal resection (UEMR) has emerged as a safe and effective technique for the management of non-pedunculated polyps.Objectives: To evaluate the efficacy and safety of UEMR for non-pedunculated colorectal polyps larger than 10 mm in a high-complexity hospital in Lima, Peru.Materials and methods: Observational, retrospective, and descriptive study of patients aged ≥18 years who underwent UEMR between January and December 2023. En bloc resection, R0 resection, recurrence, and complication rates were analyzed. Clinical, endoscopic, and histopathological data were collected.Results: A total of 119 UEMRs were performed in 91 patients, with a median age of 72 years. 60.5% of lesions were located in the right colon, and most measured between 10-19 mm. The en bloc resection rate was 80%, and the R0 resection rate was 78%. The complication rate was 15%, including one perforation and two delayed bleeding events. Most complications occurred in the right colon. Recurrence was 3.1%, observed only in piecemeal resections. Histopathological findings included low-grade (47.9%) and high-grade (28.6%) adenomas, as well as 7 carcinomas (5.8%).Conclusions: UEMR is an effective and safe technique for the treatment of non-pedunculated colorectal polyps larger than 10 mm, particularly for lesions ≤20 mm. Its advantages include a high en bloc resection rate, low complication risk, and low cost.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 3","pages":"265-272"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145507695","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}

There were no characteristic symptoms in the positive versus negative- group. The most relevant endoscopic findings in the positive group were a high frequency of antral nodular gastritis (72.1% vs. 9.8%, p<0.001) and a lower prevalence of endoscopic esophagitis (13.1% vs. 23.6%, p<0.001).

It is classified into lymphocytic colitis (LC) and collagenous colitis (CC). Its incidence has increased in developed countries, but data from Latin America remain limited. We present the case of a 65-year-old woman with fibromyalgia and recent use of duloxetine, who presented with chronic diarrhea. Colonoscopy revealed edematous mucosa with loss of vascular transparency, deep furrows with a cobblestone-like appearance, and an open dot-like surface pattern. Histopathological analysis confirmed a diagnosis of LC. After discontinuing duloxetine, the diarrhea resolved spontaneously without the need for corticosteroids. Although MC has traditionally been described as presenting with a normal-appearing colonic mucosa, studies have reported subtle and nonspecific findings such as edema, erythema, and vascular pattern abnormalities. Detection of these findings can be improved through the use of virtual chromoendoscopy and high-definition equipment. Recognizing these patterns may enhance biopsy targeting and increase the detection of this condition, especially in the evaluation of chronic diarrhea. However, endoscopic findings must be differentiated from other conditions, such as inflammatory bowel disease or ischemic colitis.","PeriodicalId":35807,"journal":{"name":"Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru","volume":"45 3","pages":"307-311"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145507500","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}

Advanced therapies, such as infliximab (IFX), have improved disease outcomes. However, the role of body mass index (BMI) in influencing IFX serum concentrations and treatment response remains unclear.Objective: This study aimed to evaluate the association between BMI and IFX serum concentrations during different disease activity phases.Materials and methods: This cross-sectional observational report categorized patients into eutrophic (BMI < 24.9kg/m²) and overweight/obese (BMI ≥ 25 kg/m²) groups. Serum IFX concentrations were measured, and disease activity was assessed using clinical, laboratory, endoscopic, and/or radiologic criteria.Results: The analysis included 102 patients (80 with CD, 22 with UC). The median serum IFX concentration in eutrophic CD patients was 3.84 μg/mL (1.66-8.82), while in overweight/obese patients was 6.00 μg/mL (1.90-10.34), with no significant difference (p=0.353). Among the 22 patients with UC, the median serum IFX concentration in eutrophic patients was 6.28μg/mL (0.860-13.66), compared to 4.23 μg/mL (2.33-12.91) in overweight/obese patients, with no significant difference (p = 0.920).

Dual therapy can achieve higher eradication rates than standard triple therapy, and the factors associated with lower eradication rates have not been fully studied. The objective of our study was to evaluate the H. pylori eradication rate and its associated factors using dual therapy versus standard triple therapy.Materials and methods: This retrospective cohort study included 1,506 patients with H. pylori infection who received dual therapy or standard triple therapy. Eradication was confirmed with urea breath test. Chi-square (χ) test was used to analyze categorical variables, and relative risk (RR) was used to assess associations between eradication rates and clinical variables.Results: Eradication was higher with dual therapy, with 84.58% (384/454) versus 73.86% (777/1052) with standard triple therapy (p<0.001). The overall eradication rate with esomeprazole was 82.13% (648/789), followed by lansoprazole at 73.70% (213/289) and pantoprazole at 70.09% (300/428) (p<0.001).
