Epidemiology and associated factors of irritable bowel syndrome in an Andean community from Peru.

INTRODUCTION: Irritable bowel syndrome (IBS) is a chronic functional bowel condition with an average world prevalence of 11.2%. Is associated with multiple factors as female sex, young age, stress, anxiety and depression which can have a negative impact on quality of life. IBS in Peru is not investigated at all specially in the Andean region. The objective of this study is to determine the prevalence and associated factors of IBS in an Andean community from Peru using the Rome IV criteria. MATERIALS AND METHODS: Cross-sectional study in a rural community dedicated to livestock and agriculture in Peru at 3,235 meters above sea level. Questionnaires provided by the Rome Foundation as the Rome IV - Diagnostic questionnaire for adults, Irritable Bowel Syndrome - Symptom Severity Scale and Bristol stool scale were used. RESULTS: 130 residents met the inclusion criteria. 46.9% were males with an average age of 54 years old. 11.54% presented red flags and were not included in the analysis. 13.1% were diagnosed with IBS and 52.9% presented constipation as predominant bowel pattern. 52.9% presented a mild course of the disease. In the chi-square analysis, factors as depression, anxiety, female sex, younger age, liquefied petroleum gas exposure for cooking and education achievement were statistically significant associated to IBS. In the logistic regression analysis, anxiety was the unique independent predictor factor with an OR of 9.6 (95% IC: 1.78-51.82). CONCLUSION: IBS is a prevalent condition in the Andean region and should be managed as a public health issue to improve quality of life.

[Comparison of the prevalence of Helicobacter pylori infection in dyspeptic patients between two institutional centers of different socio-economic strata during 2017-2018]. / Comparación de prevalencia de infección por Helicobacter pylori en pacientes con dispepsia entre dos instituciones de diferentes estratos socioeconómicos en el periodo 2017-2018.

Helicobacter pylori (Hp) infection is associated with multiple digestive problems from gastroduodenal ulcers to gastric adenocarcinoma and/or MALT lymphoma. Peru is considered a place of high prevalence of Hp. In the world, significant differences have been described in the prevalence of Hp infection associated with the socioeconomic characteristics of the population. OBJECTIVE: To compare the prevalence of Hp infection in dyspeptic patients between 2 institutional centers of different socio-economic strata during 2017-2018. MATERIALS AND METHODS: A sample of 633 patients with dyspepsia was collected retrospectively and randomly, without previous endoscopic study, or a history of Hp eradication therapy that came to the gastroenterology services of the Hospital Cayetano Heredia (HCH) in San Martin de Porres, and of the Anglo American Clinic (CAA) in San Isidro, during the period of June 2017 - July 2018 (CAA: 300 and HCH: 333). Proceeding then to review the clinical history, endoscopy report and pathological anatomy of each of them, for further statistical analysis using the SPSS program. RESULTS: A prevalence of Hp was found in the HCH of 54.1%, while in the CAA it was only 29.3% (p < 0.05), this relationship being maintained in the different age groups. Likewise, the prevalence of intestinal metaplasia (MI) in the total of patients with dyspepsia in the HCH was 33.9% (MI + in Hp + was 34.4%) and in the CAA the presence of MI without considering the Hp status was only 6.7% (MI + in HP + was 6.8%) (p < 0.05). Finally, the presence of gastric atrophy in the HCH was 26.7% and in the CAA it was 1.3% (p < 0.05). CONCLUSION: There is a clear relationship between the low socioeconomic stratum and the presence of Hp, gastric atrophy and intestinal metaplasia (the latter relationship remaining independent of Hp status).

[Independent risk factors for severity and mortality in lower gastrointestinal bleeding]. / Hemorragia digestiva baja, factores predictores de severidad y mortalidad en un hospital p úblico de Lima.

In lower gastrointestinal bleeding (LGIB), it is very important to stratify the risk of LGIB for a proper management. OBJECTIVE: Identity the independent risk factors to mortality and severity (require critical care, prolonged hospitalization, reebleding, re hospitalization, politrasfusion, surgery for bleeding control) in LGIB. MATERIALS AND METHODS: It is an analytic prospective cohort study, performed between June 2016 and April 2018 in a tertiary care hospital. Independent factors were determined using binomial logistic regression. RESULTS: A total of 98 patients were included, of which 13 patients (13,3%) died, and 56 (57,1%) met severity criteria. The independent risk factor for mortality was Glasgow scale under 15, and for severe bleeding were: Systolic blood pressure under 100 mm Hg, albumin lower than 2,8 g/dL. CONCLUSIONS: The frequency of mortality and severe LGIB is high in our population, the principal risk factors were systolic blood pressure under than 100 mm Hg, Glasgow score lower than 15, albumin lower than 2,8 g/dL. Identifying these associated factors would improve the management of LGB in the emergency room.

[Use of cyanoacrylate as a treatment of gastric varices in a public hospital in Lima - Peru]. / Uso de cianoacrilato como tratamiento de várices gástricas en un hospitalp úblico nivel III en Lima - Per ú.

OBJECTIVE: To evaluate the therapeutic success of endoscopic therapy with N-butyl-2-cyanoacrylate and to determine the re- bleeding and mortality rates. MATERIALS AND METHODS: Prospective analytical observational study of 47 cases of patients with gastric varices who were treated with N-butyl-2-cyanoacrylate, using a 1: 1 mixture with lipiodol between 2013 and 2017 in a level III public hospital in Lima - Peru. The therapeutic indication was active hemorrhage, primary or secondary prophylaxis. RESULTS: Of the 47 patients, 5 (10.6%) had active hemorrhage, control was obtained in all cases, 24 (51.1%) had stigmas of recent bleeding during endoscopy. Secondary prophylaxis was performed in 16 (34%) patients and primary prophylaxis in 2 (4.7%). 59.6% required a single session with a total volume of cyanoacrylate (ml / patient) of 1.28 ± 0.44. The endoscopic finding was GOV-2 in 78.7% of the cases, IGV-1 in 12.8% and GOV-1 in 8.5%. Seven patients (14.8%) presented late re- bleeding, with successful new therapy in 6 of them, one dying due to therapy failure. Of the six (12.76%) patients who died in total, 5 (83.3%) were due to other causes. No adverse events related to the therapy were reported. No adverse events were reported. Variceal obturation was observed in 28 (59.5%) patients. CONCLUSIONS: Endoscopic management of gastric varices with cyanoacrylate is a safe and effective treatment, with low recurrence and mortality rates.

[Colonic balantidiasis: report of a fatal case and review of the literature]. / Balantidiasis colónica: reporte de un caso fatal y revisión de la literatura.

Balantidiasis is a zoonosis produced by Balantidium coli, which inhabits the large intestine of the pig and man. Infection is uncommon in humans and mainly affects the colon. It occurs more frequently in developing countries, tropical and subtropical regions. Colonic balantidiasis can occur in most cases asymptomatically and reach in the most severe cases such as dysenteric diarrhea that can be complicated by low digestive bleeding and even perforation. We present the case of a 72-year-old man, from the Peruvian highlands, who was a farmer and breeder of swine and sheep, who came for 3 months of illness, initially characterized by liquid stools with bloodless mucus, abdominal pain, nausea, vomiting and in the last month of illness he presents dysenteric diarrhea. Colonoscopy was performed due to suspicion of infectious colitis, Balantidium coli trophozoites were found in the fresh sample and colonic tissue biopsy. Patient receives treatment with amebicide and antibacterial without clinical improvement, presenting as a complication multiple perforation in the sigmoid colon, treated with resection and terminal colostomy. Finally, the patient died despite receiving medical and surgical treatment.

Clinical and endoscopic findings of patients with cutaneous Kaposi sarcomaand gastrointestinal involvement. Experience in a single center of Lima-Peruin the last 3 years.

INTRODUCTION: Kaposi sarcoma is a low-grade angioproliferative neoplasm strongly associated with infection by herpes virus type 8 (HHV-8). Gastrointestinal (GI) involvement is an infrequent finding, whose clinical and endoscopic characteristics are poorly defined in the literature. OBJECTIVE: The aim of our study was to describe the clinical and endoscopic findings of patients with gastrointestinal Kaposi Sarcoma. MATERIALS AND METHODS: We reviewed all clinical histories, endoscopic and anatomopathologic reports of all patients with cutaneous Kaposi sarcoma (CKS) who came to Cayetano Heredia Gastroenterology Service during the period between August 2015 to October 2018. We included all patients with CKS that had gastrointestinal involvement confirmed with biopsy. RESULTS: We found 50 patients with cutaneous Kaposi sarcoma. Thirteen patients had gastrointestinal Kaposi sarcoma (26%). 53.8% (7/13 cases) were asymptomatic. 92.3% (12/13 cases) had HIV infection. Nine of the twelve HIV+ patients had CD4 count below 200 cells/µl. When Kaposi affects GI tract, the mayority have multiple GI organs affected. Stomach and colon are the most common sites affected. CONCLUSION: Gastrointestinal involvement was presented in 26% of our patients with cutaneos Kaposi sarcoma, a half of them had no GI symptoms. The majority of cases were young male and had HIV in AIDS stage. The mortality in our series was 15.3% at 6 months of follow-up.

[Fulminating ischemic hepatitis induced by severe cardiac dysfunction: case report]. / Hepatitis isquémica fulminante inducida por disfunción cardiaca severa: reporte de caso.

Ischemic Hepatitis is an uncommon entity in daily clinical practice with a prevalence of 0.16 to 0.5% among patients admitted to a critical care unit, associated with an approximate 60% mortality rate. This liver disease is characterized by a rapid and marked increase (more than 20 times the normal value) of the level of transaminases secondary to a severe and persistent hepatic hypoperfusion caused by multiple etiologies, which may be transient when the triggering cause is timely identified and appropiately treated. The case of an elderly adult patient with a clinical, epidemiological and biochemical profile compatible with ischemic hepatitis secondary to severe cardiac dysfunction is presented below.

[Accuracy of ASGE predictors in diagnosis of coledocolithiasis in a public hospital of Lima, Peru]. / Precisión de los predictores de la ASGE en el diagnóstico de coledocolitiasis en un hospital público de Lima, Perú.

BACKGROUND: The predictors proposed by the American Society of Gastrointestinal Endoscopy (ASGE) are commonly used topredict the presence and management of choledocholithiasis. OBJECTIVE: To evaluate the performance and precision of thepredictors of choledocholithiasis proposed by ASGE. MATERIALS AND METHODS: Prospective and longitudinal study performed ata third level hospital during January 2015 to June 2017. All patients with high and intermediate probability of choledocholithiasiswho underwent endoscopic retrograde cholangiopancreatography (ERCP) were included according to the criteria proposedby the ASGE. RESULTS: A total of 246 patients with suspected choledocholithiasis were analyzed. Of the 228 patients withhigh probability criteria 144 (63.2% = performance) had choledocholithiasis in ERCP with an accuracy of 62% (sensitivity:94.1% and specificity: 9.7%). Among the 18 patients with intermediate probability criteria, 9 (50% = performance) hadcholedocholithiasis with an accuracy of 38% (sensitivity: 5.9% and specificity: 90.3%). In the multivariate analysis, the presenceof stone in the bile duct by ultrasonography (OR: 1.937, 95% CI 1.048-3.580, p=0.035) and age 55 and over (OR: 2.121, 95%CI, 1.101-4.088, p=0.025) were the strongest predictors for choledocholithiasis. CONCLUSIONS: The application of the criteriaof the ASGE to predict the probability of choledocholithiasis, in our population has a performance greater than 50%, however,it is necessary to improve these parameters to avoid an unnecessary performance of ERCP.

Antecedentes: Habitualmente se utilizan los predictores propuestos por la Sociedad Americana de Endoscopía Gastrointestinal (ASGE) para predecir la presencia y manejo de coledocolitiasis. Objetivo: Evaluar el rendimiento y precisión de los predictores de coledocolitiasis propuestos por la ASGE. Materiales y métodos: Estudio prospectivo y longitudinal realizado en un hospital de tercer nivel desde enero del 2015 hasta junio del 2017. Se incluyeron a todos los pacientes con probabilidad alta e intermedia de coledocolitiasis y que fueron sometidos a colangiopancreatografía retrógrada endoscópica (CPRE) según los criterios propuestos por la ASGE. Resultados: Se analizó un total de 246 pacientes con sospecha de coledocolitiasis. De los 228 pacientes con criterios de alta probabilidad, 144 (63,2% = rendimiento) tenían coledocolitiasis en la CPRE con una precisión de 62% (sensibilidad: 94,1% y especificidad: 9,7%). Entre los 18 pacientes con criterios de probabilidad intermedia: 9 (50% = rendimiento) tenían coledocolitiasis con una precisión de 38% (sensibilidad: 5,9% y especificidad: 90,3%). En el análisis multivariado la presencia de cálculo en el colédoco por ecografía (OR: 1,937; IC 95% 1,048- 3,580; p=0,035) y la edad mayor de 55 años (OR: 2,121; IC 95% 1,101-4,088; p=0,025) fueron los predictores más fuertes para coledocolitiasis. Conclusiones: La aplicación de los criterios de la ASGE para predecir probabilidad de coledocolitiasis, en nuestra población tiene un rendimiento mayor del 50%; sin embargo, se necesita mejorar estos parámetros para evitar una realización innecesaria de CPRE.

On physical examination, hepatomegaly of 6cm below the right costal margin was detected. CT scan showed multiple liver metastases. An upper endoscopy found multiple hyperpigmented lesions on the second portion of the duodenum. Histology and immunohistochemistry studies concluded it was duodenal melanoma. Skin and ocular examination did not reveal associated neoplastic lesions.

[Gastric hemangioma as a cause of upper gastrointestinal bleeding]. / Hemangioma gástrico como causa de hemorragia digestiva alta.

Gastric hemangioma as a cause of upper gastrointestinal bleeding (UGIB) is a rare event. We present the case of an 83 years old male with a history of abdominal pain, vomiting and melena, along with an 8 Kg weight loss. The upper gastrointestinal endoscopy showed an elevated, ulcerated lesion in the gastric antrum with a visible vessel, for which he receives endoscopic therapy. In the abdominal computed tomography, a contrast enhancing, well-circumscribed mass attached to the gastric wall is observed. Due to the persistence of the UGIB, the patient suffers hemodynamic decompensation and undergoes exploratory laparotomy, where a vascularized mass is found. The pathology report informs a gastric cavernous hemangioma.
