RESUMO

Primary anorectal melanoma is a rare malignant melanocytic neoplasm; its principal manifestation is rectal bleeding. It has an ominous prognosis with a five-year survival rate of 10%. The case of a 56-year-old woman with rectal bleeding and the sensation of a rectal mass is presented. A polypoid lesion, resected transanally, was documented in the distal rectum during the colonoscopy. The histological study confirmed a primary anorectal melanoma.


El melanoma anorrectal primario es una neoplasia melanocítica maligna poco frecuente, su principal manifestación es el sangrado rectal. Tiene un pronóstico ominoso con una tasa de sobrevida del 10% a 5 años. Se presenta el caso de una mujer de 56 años con rectorragia y sensación de masa rectal. Durante la colonoscopia se documentó una lesión polipoide en el recto distal, que se resecó por vía transanal. El estudio histológico confirmó la presencia de un melanoma anorrectal primario.

RESUMO

Traditionally, the initiation of enteral nutrition after a percutaneous endoscopic gastrostomy (PEG) is performed between 12 and 24 hours. Different research suggests that early initiation might be a safe option. Our aim was to determine whether starting enteral nutrition 4 hours after performing PEG is a safe practice in terms of risk of intolerance, complications, or death, compared to starting it at 12 hours. We carried out a prospective, randomized, multicenter study in third and fourth level institutions in Bogotá and Cundinamarca, between June 2020 and May 2022, 117 patients were included who were randomized into 2 groups, group A with early nutrition initiation (4 hours), and standard group B (12 hours). The most frequent mechanism of dysphagia was cerebrovascular disease (43%), followed by complications of COVID19 infection (26%). There were no statistically significant differences between the groups evaluated regarding the percentage of intolerance to nutrition, RR = 0.93 (CI 0.30-2.90), there were also no differences in terms of postoperative complications, (RR) = 0.34 (CI 0.09-1.16), and no differences were found in mortality between the evaluated groups, (RR) = 1.12 (CI 0.59-2.15). In conclusion, early initiation of nutrition through the gastrostomy, 4 hours after performing the PEG, is a safe behavior that is not related to greater intolerance to nutrition, complications, or death, compared to later initiation.

RESUMO

Obesity is a global epidemic. According to the World Health Organization (WHO), it is an abnormal or excessive accumulation of fat that can harm health. Its incidence is increasing alarmingly in developing countries. It is also a significant risk factor for developing chronic diseases such as type 2 diabetes mellitus, arterial hypertension, coronary disease, non-alcoholic fatty liver disease, and musculoskeletal disorders such as osteoarthritis. Furthermore, associations have been found between obesity and the development of prostate, liver, gallbladder, kidney, colon, endometrial, breast, and ovarian cancer. Bariatric and metabolic surgery is the most effective treatment for morbid obesity and its comorbidities. This surgery can reduce general mortality by 40% at ten years due to cardiovascular outcomes, diabetes, or cancer and improve metabolic diseases such as type 2 diabetes.


La obesidad es una epidemia global, según la Organización Mundial de la Salud (OMS) se define como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud, su incidencia está aumentando de forma alarmante en los países en desarrollo. Asimismo, es un factor de riesgo importante para el desarrollo de enfermedades crónicas como la diabetes mellitus tipo 2, hipertensión arterial, enfermedad coronaria, enfermedad del hígado graso no alcohólico y trastornos musculoesqueléticos como la osteoartritis; además, se han encontrado asociaciones entre la obesidad y el desarrollo del cáncer de próstata, hígado, vesícula biliar, riñón, colon, endometrio, mama y ovarios. La cirugía bariátrica y metabólica es el tratamiento más eficaz para la obesidad mórbida y sus comorbilidades, esta cirugía puede reducir la mortalidad general en un 40% a los diez años por desenlaces cardiovasculares, diabetes o cáncer, como también mejorar enfermedades metabólicas como la diabetes tipo 2.

RESUMO

Tradicionalmente, el inicio de nutrición enteral, luego de una gastrostomía endoscópica percutánea (GEP) se realiza entre 12 a 24 horas. Diferentes investigaciones sugieren que iniciarla más temprano podría ser una opción segura. El objetivo es determinar si el inicio de nutrición enteral a las 4 horas después de realizar GEP es una conducta segura en cuanto al riesgo de intolerancia, complicaciones o muerte, comparado con iniciarla a las 12 horas. Realizamos un estudio prospectivo, aleatorizado, multicéntrico en instituciones de tercer y cuarto nivel de Bogotá y Cundinamarca, entre junio de 2020 y mayo de 2022, se incluyeron 117 pacientes que fueron aleatorizados en 2 grupos, el grupo A de inicio temprano de nutrición (4 horas), y el grupo B de inicio estándar (12 horas). El mecanismo más frecuente de disfagia fue la enfermedad cerebrovascular (43%), seguido por complicaciones de infección por COVID-19 (26%). No hubo diferencias estadísticamente significativas entre los grupos evaluados respecto al porcentaje de intolerancia a la nutrición, RR = 0,93 (IC 0,30-2,90), tampoco hubo diferencias en términos de complicaciones posoperatorias, (RR) = 0,34 (IC 0,09-1,16), y no se encontraron diferencias en la mortalidad entre los grupos evaluados, (RR) = 1,12 (IC 0,59 - 2,15). En conclusión, el inicio de nutrición a través de la gastrostomía de forma temprana, 4 horas después de la realización de la GEP es una conducta segura que no se relaciona con una mayor intolerancia a la nutrición, complicaciones o muerte, en comparación con un inicio más tardío.

RESUMO

Introduction: gastrointestinal involvement in COVID-19 occurs in approximately 20% of patients and may include nausea, vomiting, abdominal pain, diarrhea or abnormal liver function tests. In our country, the characteristics of gastrointestinal involvement in COVID-19 patients have not been studied. Objectives: to determine the prevalence of gastrointestinal and liver involvement in patients with COVID-19 treated at two hospitals in Bogotá, Colombia. To determine the association between COVID-19 gastrointestinal involvement and length of hospital stay, severity and mortality. Design and methodology: a cross-sectional study carried out at two hospitals in a hospital subnetwork in Bogotá, Colombia from February 2020 to March 2021. Results: a total of 1,176 patients with a positive reverse transcription polymerase chain reaction (RT-PCR) were included. Gastrointestinal manifestations occurred in 50% (95%CI 47-52%), with the most frequent being diarrhea in 18.4%, odynophagia in 17.6%, anorexia in 14.7% and abdominal pain in 8.8%. An association was found between diarrhea during hospitalization and prolonged hospitalization (OR 1.93 95%CI 1.19-3.13), and between gastrointestinal bleeding on admission and death (OR 3.13, 95%CI 1.1-9.1), among others. Abnormal liver function tests occurred in 46% (95%CI 43-49%) and were more frequent in patients with severe disease and those who died. Conclusions: the prevalence of gastrointestinal manifestations in patients with COVID-19 was 50%. Diarrhea was associated with a longer hospital stay, and gastrointestinal bleeding was associated with respiratory failure and death. Forty-six percent of patients had abnormal liver function tests, with elevated transaminases being the most frequent. Elevated aspartate transaminase (AST) on admission was associated with greater mortality. (Acta Med Colomb 2022; 48. DOI:https://doi.org/10.36104/amc.2023.2729).

RESUMO

Abstract Background: Helicobacter pylori (H. pylori) affects 50% of the human population. The efficacy of the usual treatments has decreased due to increased antibiotic resistance, except for that of amoxicillin, tetracycline, furazolidone and bismuth. Recently, there has been a new interest in dual therapy with high-dose proton pump inhibitors (PPI) and amoxicillin as initial and rescue treatment. There are no studies on this topic in our setting. Objective: to determine the efficacy of dual therapy with high-dose IPP and amoxicillin for eradicating H. pylori. Materials and methods: this was a quasi-experimental study carried out from December 2019 to July 2020 in people over the age of 18 with histologically confirmed H. pylori. All received 40 mg of esomeprazole half an hour before breakfast, lunch and dinner, plus 1 gram of oral amoxicillin every eight hours for 14 days. Eradication was determined by fecal antigens (OnSiteTM H. pylori Biotech Inc.) after four weeks of treatment. Results: 108 patients with an average age of 67 years were included, 70% of whom were women. Eradication per protocol (PP) and intention to treat (ITT) was 86% (95%CI 79.4-92.5%) for both. In previously treated patients (26%) the efficacy was 85.7% (95%CI 71.8-99.5%). Adverse events were mild in 31%, especially nausea (16%) and abdominal distension (14%). Treatment was not suspended in any patient. Conclusion: Dual therapy is effective, easy to administer, and has few adverse effects. It would be a good option in our setting as initial or rescue therapy. Larger studies are needed to confirm our results. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.2091).

RESUMO

Abstract Introduction: gastroesophageal reflux disease (GERD) affects one out of eight people in Colombia. Its characteristic symptoms are heartburn and reflux. The cornerstone of treatment is proton pump inhibitors (PPIs), with a clinical response in 58-80% of patients. Of those who do not respond, 75-90% have a superimposed functional disorder and could be treated by adding visceral neuromodulators. Objective: to evaluate the impact of optimizing the treatment of patients with GERD when there is no response to esomeprazole (ESO). Materials and methods: a prospective study in patients with no clinical response (more than two reflux episodes per week) who were treated with 40 mg of ESO half an hour before breakfast along with the recommendation to lose weight if BMI >25, stop smoking and manage stress; and, finally, increasing the ESO dose to 40 mg on an empty stomach and before dinner. When all of this was done and symptoms persisted, 12.5 mg of amitriptyline were added at night. The response was evaluated every 12 weeks. Results: a total of 529 patients were eligible and 149 met the inclusion criteria. With treatment optimization, 111 patients had a clinical response without using amitriptyline (74.5%; 95%CI 67.2 81.4). Amitriptyline was added in 22 patients (14.8%), 15 of whom responded (68.2%; 95%CI 47.04-89.32%). Eight patients experienced drowsiness (53.3%). A relationship was found between PPI treatment compliance and clinical response (p<0.0001). Conclusions: in patients with GERD, PPI treatment optimization improves 74.5% (95%CI 67.2 81.4) of the patients, and adding amitriptyline for those who do not improve achieves improvement in 68.2% of those who did not improve with two doses of ESO. Sequential management achieved a cumulative improvement in symptom control in 85% (95%CI 78.6-90.4) of the patients. (Acta Med Colomb 2021; 46. DOI: https://doi.org/10.36104/amc.2021.2041).


Resumen Introducción: la enfermedad por reflujo gastroesofágico (ERGE) afecta a una de cada ocho personas en Colombia. Sus síntomas característicos son pirosis y regurgitación. La piedra angular del tratamiento son los inhibidores de bomba de protones (IBP) con respuesta clínica en 58-80%. En quienes no responden 75-90% tienen un trastorno funcional superpuesto y se podrían tratar adicionando neuromoduladores viscerales. Objetivo: evaluar el impacto que tiene optimizar el tratamiento en pacientes con ERGE cuando no hay respuesta a esomeprazol (ESO). Material y métodos: estudio prospectivo en pacientes sin respuesta clínica (más de dos episodios de reflujo por semana) tratados con ESO 40 mg media hora antes del desayuno y simultáneamente recomendaciones para bajar de peso si IMC >25, dejar de fumar y controlar el estrés, y finalmente aumentado la dosis de ESO a 40 mg en ayunas y antes de la cena. Cuando se cumplió todo lo anterior y persistían los síntomas, se adicionó amitriptilina 12.5 mg por la noche. Cada 12 semanas se evaluaba la respuesta. Resultados: hubo 529 pacientes elegibles y 149 cumplieron los criterios de inclusión. Optimizando el tratamiento 111 pacientes tuvieron respuesta clínica sin la utilización de amitriptilina (74.5%; IC95% 67.2-81.4). En 22 se adicionó amitriptilina (14.8%) y de estos respondieron 15 pacientes, 68.2% (IC95% 47.04-89.32%). En ocho pacientes hubo somnolencia (53.3%). Se encontró relación entre el cumplimiento del tratamiento con IBP y la respuesta clínica (p<0.0001). Conclusiones: en pacientes con ERGE la optimización del tratamiento con IBP mejora el 74.5% (IC95% 67.2-81.4) de los pacientes y la adición de amitriptilina a quienes no mejoran, logra mejorar el 68.2% de quienes no mejoraban con dos dosis de ESO. Con el manejo secuencial se logró mejoría acumulativa en el control de los síntomas de 85% (IC95% 78.6-90.4) de los pacientes. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.2041).

RESUMO

Resumen Del 20% al 30% de los pacientes con colitis ulcerativa (CU) son sometidos a cirugía, ya sea por intratabilidad, curso fulminante, aparición de displasia o cáncer de colon. La cirugía de elección es la proctocolectomía con reservorio ileoanal. Sin embargo, el 20%-50% de los pacientes presentan reservoritis a 10 años. El diagnóstico se realiza con base en las manifestaciones clínicas, las alteraciones endoscópicas y la histología. Los medicamentos utilizados en el tratamiento de la CU no son tan eficaces en la reservoritis y el tratamiento de primera línea es los antibióticos. Dependiendo de la respuesta inicial y el curso clínico de la entidad, se elegirá el tratamiento posterior. En esta revisión se discuten los aspectos más importantes con respecto a la epidemiología, diagnóstico, patogénesis y tratamiento de la reservoritis.


Abstract Between 20% and 30% of patients with ulcerative colitis (UC) undergo surgery because it is not treatable or because it is associated with a fulminant course, dysplasia, or colon cancer. The surgery of choice is proctocolectomy with ileal-anal pouch. However, 20%-50% of patients present with pouchitis 10 years after surgery. The diagnosis is made based on clinical manifestations, endoscopic alterations, and histology. The drugs used in the treatment of UC are not as effective in pouchitis and the first-line treatment is antibiotics administration. Depending on the initial response and clinical course of the condition, subsequent treatment will be chosen. This review discusses the most important aspects of the epidemiology, diagnosis, pathogenesis, and treatment of pouchitis.

RESUMO

INTRODUCTION: Proton pump inhibitors (PPIs) are a group of drugs that are essential for the treatment of acid-related disorders, such as gastroesophageal reflux (GERD), dyspepsia, gastric ulcers and Helicobacter pylori (H. pylori) infection. PPIs such as omeprazole, esomeprazole, pantoprazole and lansoprazole are metabolized by the CYP2C19 enzyme, which is encoded by a polymorphic gene. Four polymorphisms have an impact on the speed of PPI metabolism: CYP2C19*1/*1 (extensive metabolizers), CYP2C19*2/*2 (intermediate metabolizers), CYP2C19*3/*3 (poor metabolizers) and CYP2C19*17/*17 (ultrarapid metabolizers). Extensive and ultrarapid metabolizers inactivate PPIs quickly, which consequently causes low plasma concentrations of PPIs, while intermediate or poor metabolizers have higher plasma concentrations of PPIs and, therefore, PPIs have greater therapeutic efficacy in individuals with these polymorphisms. OBJECTIVE: To determine the frequency of genetic polymorphisms of the CPY2C19 enzyme in Bogotá, Colombia. METHODS: This observational study was conducted in Bogotá between 2012 and 2015 and was part of a clinical trial (ID: NCT03650543). It included 239 subjects with dyspepsia, H. pylori infection, or GERD symptoms. CYP2C19 genotyping was performed on gastric biopsy samples. Polymorphisms *1, *2, and *3 were analyzed by real-time PCR (Roche®), and PCR-RFLP was used to determine the presence of polymorphism *17. RESULTS: The distribution of different types of PPI metabolizers was as follows: extensive (70.7%), ultrarapid (12.9%), intermediate (8.8%) and poor (0.8%). CONCLUSION: The population studied consisted mainly of extensive and ultrarapid PPI metabolizers. These findings show that it is necessary to increase PPI doses in this group of subjects or to use PPIs that are not metabolized by CYP2C19 (rabeprazole). This is the first Colombian work to identify ultrarapid metabolizers.

RESUMO

Resumen El manejo de la nutrición en pancreatitis aguda ha sido cuestión de debate. Durante muchos años el concepto de reposo pancreático fue generalizado y aceptado en el manejo de la pancreatitis aguda. Actualmente se conoce que la nutrición temprana permite mantener la integridad de la barrera intestinal, que previene la aparición de complicaciones infeccionas y se asocia con una menor estancia hospitalaria, menos complicaciones y un mejor pronóstico. En esta revisión se discuten las principales ventajas de la nutrición temprana en pancreatitis aguda, la seguridad de la misma y la vía de administración.


Abstract Nutrition management in acute pancreatitis has been a matter of debate worldwide. For many years, the concept of pancreatic rest was widespread and accepted to treat acute pancreatitis. However, current knowledge of early nutrition allows maintaining the intestinal barrier's integrity, preventing the occurrence of infectious complications, which is associated with a shorter hospital stay, fewer complications, and better prognosis. This review presents the main advantages of early nutrition in acute pancreatitis, its safety, and the route of administration.

RESUMO

Resumen Objetivo: La enfermedad de Crohn es un trastorno inflamatorio idiopático de etiología desconocida con características genéticas, inmunológicas e influencias del medio ambiente. La incidencia y la prevalencia de la enfermedad de Crohn han aumentado en Colombia. El tratamiento de estos pacientes no es fácil y ha evolucionado en los últimos años; por lo tanto, es necesario desarrollar una guía de práctica clínica en Colombia, orientada al tratamiento de esta compleja enfermedad, para unificar criterios. Materiales y métodos: Esta guía fue desarrollada por un equipo multidisciplinario con apoyo de la Asociación Colombiana de Gastroenterología, el Grupo Cochrane ITS y el Instituto de Investigaciones Clínicas de la Universidad Nacional de Colombia. Se desarrollaron preguntas clínicas relevantes a la entidad y se realizó la búsqueda de guías nacionales e internacionales en bases de datos especializadas. Las guías existentes fueron evaluadas en términos de calidad y aplicabilidad. El Grupo Cochrane realizó la búsqueda sistemática de la literatura. Las tablas de evidencia y recomendaciones fueron realizadas usando la metodología GRADE. Resultados: Se realizó una guía de práctica clínica basada en la evidencia, para el tratamiento tanto médico como quirúrgico de la enfermedad de Crohn en población adulta en Colombia. Se diseñaron algoritmos de manejo teniendo en cuenta la actividad, el comportamiento y la localización de la enfermedad. Conclusiones: Se estableció que una adecuada evaluación clínica, endoscópica e imagenológica, así como una estratificación de riesgo individual son importantes para el manejo, y se especificaron las indicaciones para el adecuado tratamiento tanto médico como quirúrgico de estos pacientes.


Abstract Objective: Crohn's disease is an idiopathic inflammatory disorder of unknown origin, influenced by genetic, immunological, and environmental factors. The incidence and prevalence of Crohn's disease have increased in Colombia. The treatment of these patients is not easy and has improved in recent years. Therefore, it is necessary to develop the Colombian Clinical Practice Guideline to guide the treatment of this complex disease and unify criteria. Materials and methods: The present guideline was carried out by a multidisciplinary team with support from the Asociación Colombiana de Gastroenterología, the Cochrane ITS Team, and the Clinical Research Institute of the Universidad Nacional de Colombia. Clinical questions regarding this disease were developed, and national and international guidelines were searched in specialized databases. The existing guidelines were evaluated in terms of quality and applicability. The Cochrane Group conducted a systematic search of the existing literature. Evidence tables were elaborated, and recommendations were made using the GRADE methodology. Results: An evidence-based clinical practice guideline was developed for the medical and surgical treatment of Crohn's disease in the adult population in Colombia. Treatment algorithms were designed, taking into account the activity, behavior, and location of the disease. Conclusions: It was established that proper clinical, endoscopic, and imaging assessment, as well as individual risk stratification, are important for treatment. Also, the indications for adequate medical and surgical treatment of these patients were specified.

RESUMO

Resumen Introducción: la coledocolitiasis (CLDL) puede ser difícil de diagnosticar. Su importancia radica en sus potenciales complicaciones y en que el tratamiento se realiza mediante colangiopancreatografía retrógrada endoscópica (CPRE), un procedimiento con riesgo de generar complicaciones. Se han propuesto guías para su diagnóstico y la más empleada es la de la ASGE (American Society for Gastrointestinal Endoscopy), cuyo rendimiento no es ideal. Recientemente, se ha publicado la guía británica. Este estudio se realizó para establecer el rendimiento de ambas guías. Materiales y métodos: estudio prospectivo realizado entre agosto 1 de 2017 y julio 31 de 2018. Resultados: se incluyeron 300 pacientes para el análisis. Se realizó una CPRE en 145 pacientes y se confirmó la existencia de CLDL en 124 de ellos (85,5 %). La mediana de aspartato aminotransferasa (AST) y alanina aminotransferasa (ALT) fue mayor en los que tuvieron CLDC (207 mg/dL y 290 mg/dl, respectivamente). Entre tanto, la tasa de complicaciones posteriores a la CPRE fue del 5,5 %. El análisis multivariado no encontró una asociación significativa para alguna variable predictora de CLDL. En pacientes con alta probabilidad, las guías británicas tuvieron una sensibilidad del 65 % y una especificidad del 33 %, mientras que las guías ASGE mostraron una sensibilidad del 74 % y una especificidad del 28 %. En probabilidad intermedia fueron menos eficientes. Conclusiones: los criterios de la ASGE y la BSG (British Society of Gastroenterology) no tienen un buen desempeño en la población estudiada, a fin de discriminar la existencia o no de CLDL. La guía de la ASGE mostró un mejor rendimiento en general que las guías británicas.


Abstract Introduction: Choledocholithiasis (CDL) may be difficult to diagnose. The relevance of making a timely diagnosis lies in its potential negative effects and the fact that treatment requires performing endoscopic retrograde cholangiopancreatography (ERCP), which is a procedure with a high risk of complications. Several guidelines have been proposed for its diagnosis, including the ASGE Guidelines, which are the most widely used although they do not have an ideal performance, and the guidelines recently published by the BSG. The objective of this study was to compare the performance of both guidelines. Materials and methods: Prospective study carried out between August 1, 2017, and July 31, 2018. Results: 300 patients were included for analysis. 145 underwent ERCP and choledocholithiasis was confirmed in 124 of them (85.5%). Median AST and ALT levels were higher in patients with choledocholithiasis (207 mg/dL and 290 mg/dL). The rate of post-ERCP complications was 5.5%. Multivariate analysis found no significant association for any predictor of CDL. Regarding the "high probability" score, the BSG guidelines had sensitivity of 65% and specificity of 33%, while the ASGE guidelines had sensitivity of 74% and specificity of 28%. Both guidelines were less efficient for "intermediate probability". Conclusions: The ASGE and BSG criteria do not perform well in the population studied to determine whether they had CDL. The ASGE guidelines had a better overall performance than the BSG guidelines.

RESUMO

Resumen Introducción: la coledocolitiasis (CDL) afecta al 10 % de los pacientes con cálculos en la vesícula biliar. La obstrucción del colédoco se asocia a pancreatitis, colangitis y ruptura del colédoco. Clásicamente, la obstrucción biliar es considerada cuando se aumentan la fosfatasa alcalina, la γ-glutamil-transpeptidasa (GGTP) y las bilirrubinas. En la última década, se ha encontrado que hasta un 10 % de los pacientes con CDL presentan elevaciones de las aminotransferasas. En Latinoamérica, no se ha estudiado esta alteración. El objetivo del presente trabajo fue determinar la prevalencia de la elevación de transaminasas y su evolución. Metodología: estudio de casos y controles. Se determinó la alanina aminotransferasa (ALT) al ingreso, a las 48 h y a las 72 h. Si la ecografía era normal, se realizó una colangiorresonancia o una ecoendoscopia, así como una colangiopancreatografía retrógrada endoscópica (CPRE) cuando fue necesario. Resultados: se incluyeron 72 pacientes con CDL (casos) y 128 con colecistitis, sin CDL (controles). En los casos, el 83 % tuvo un aumento de ALT, mientras que el 56,9 % presentó una elevación de 2-9 veces, el 16 %, de 10-20 veces, y el 8,3 % mostró una elevación >20 veces. En contraste, a las 48 h, las ALT descendieron al 30 % y a las 72 h al 56 %. Entre tanto, en los controles hubo un aumento de ALT en el 27,3 %, mientras que en el 15,6 % se observó una elevación de 2-9 veces, en el 7,8 %, de 10-20 veces, y >20 veces en el 2,9 %. La combinación de cólico biliar y la elevación de ALT tuvo un valor predictivo positivo (VPP) para CDL del 72 %, así como un valor predictivo negativo (VPN) del 87,7 %. Conclusión: cuando hay un cólico biliar y una elevación de ALT es imperativo descartar una CDL, y si la ecografía es normal, es necesario realizar una colangiorresonancia o una ecoendoscopia biliopancreática.


Abstract Introduction: Choledocolithiasis (CLD) affects 10% of patients with gallstones. Bile duct obstruction is associated with pancreatitis, cholangitis, and rupture of the common bile duct. This condition usually presents with increased alkaline phosphatase, GGTP and bilirubin levels. In the last decade, it has been found that up to 10% of patients with CLD have elevated aminotransferases levels. In Latin America, this alteration has not been studied. The aim of the present work was to determine the prevalence of transaminase elevation and its evolution. Methodology: Case-control study. ALT was measured on admission, at 48 h and at 72 h. If ultrasound was normal, MRCP and/or echo-endoscopy and ERCP were performed, as appropriate. Results: A total of 72 patients with choledocholithiasis (CLD) (cases) and 128 with cholecystitis without choledocholithiasis (controls) were included. Among the cases, 83% had increased ALT levels, which was 2-9 times higher in 56.9%, 10-20 times higher in 16%, and more than 20 times higher in 8.3%. At 48 hours, those levels decreased by 30% and at 72 hours by 56%. In turn, in 27.3% of the controls, ALT was 2-9 times higher in 15.6%, 10-20 times higher in 7.8% and more than 20 times higher in 2.9%. The combination of biliary colic and ALT elevation had a positive predictive value (PPV) for CLD of 72% and a negative predictive value (NPV) of 87.7%. Conclusion: When biliary colic and ALT elevation are reported, it is imperative to rule out choledocholithiasis. If the ultrasound is normal, MRCP and/or biliopancreatic endoscopy should be performed.

RESUMO

INTRODUCCIÓN: El impacto clínico de la elevación de la cabecera de la cama en pacientes con enfermedad por reflujo gastroesofágico es incierto, por inconsistencia y limitaciones metodológicas en estudios previos. PACIENTES Y MÉTODOS: Ensayo clínico controlado aleatorizado unicéntrico simple-ciego cruzado 2x2, en 39 pacientes con enfermedad por reflujo gastroesofágico tratados farmacológicamente. La intervención fue elevar la cabecera de la cama a 20 cm de altura durante 6 semanas y luego a dormir sin inclinación otras 6 semanas, con un lavado de 2 semanas entre períodos. El desenlace primario fue el cambio ≥ 10% de la puntuación RDQ y los desenlaces secundarios fueron el cambio ≥ 10% de la puntuación SF-36, preferencia del paciente y frecuencia de eventos adversos. RESULTADOS: 27 (69,2%) pacientes que utilizaron la intervención cumplieron el desenlace primario, vs. 13 (33,3%) pacientes en el grupo control (RR: 2,08; IC95%: 1,19 - 3,61). No se encontró efecto en la puntuación SF-36 (RR: 1,11; IC95%: 0,47 - 2,60). La preferencia por la intervención fue del 77,1% y la proporción de eventos adversos fue del 54,0%. CONCLUSIÓN: La elevación de la cabecera de la cama redujo los síntomas de reflujo, pero no tuvo efecto en la calidad de vida. Por un balance riesgo-beneficio no óptimo, se requieren estudios adicionales antes de recomendar esta intervención (IBELGA, identificador ClinicalTrials.gov NCT02706938)


BACKGROUND: The clinical impact of head-of-bed elevation in patients with gastro-oesophageal reflux disease is unclear, because of inconsistency and methodological limitations of previous studies. PATIENTS AND METHODS: A randomised single-blind single-centre controlled clinical trial with a 2x2 cross-over design, in 39 pharmacologically treated patients with gastro-oesophageal reflux disease. Active intervention was to use a head-of-bed-elevation of 20cm for 6 weeks and then to sleep without inclination for 6 additional weeks, with a wash-out of 2 weeks between periods. The primary outcome was a change ≥ 10% in RDQ score and secondary outcomes were a change ≥ 10% in SF-36 score, patient preference and frequency of adverse events. RESULTS: 27 (69.2%) patients who used the intervention reached the primary outcome vs 13 (33.3%) patients in the control group (RR: 2.08; 95 CI%: 1.19 - 3.61). No effect was found in SF-36 score (RR: 1.11; 95% CI: 0.47 - 2.60). Preference favouring the intervention was 77.1% and adverse event proportion was 54.0%. CONCLUSION: Head-of-bed elevation improved reflux symptoms but there was no effect on quality of life. The finding of a non-optimal risk-benefit ratio warrants additional studies before this intervention can be recommended (IBELGA, ClinicalTrials.gov identifier NCT02706938)

RESUMO

Resumen Introducción: el dolor abdominal crónico es frecuente en consulta externa. El enfoque tradicional es investigar patologías viscerales. El 50 % de esos pacientes finalmente tiene dolor crónico de la pared abdominal (DCPA), generalmente secundario a atrapamiento del nervio cutáneo anterior. Esta entidad se identifica con el signo de Carnett. El tratamiento de elección es infiltrar con lidocaína los puntos dolorosos. Con una postinfiltración hay una mejoría significativa en el 85 %-90 % de los pacientes. Se desconoce la duración de la mejoría postinfiltración. El objetivo de este trabajo es determinar la respuesta sostenida en seguimientos a 1 y 2 años. Materiales y métodos: estudio de cohorte, retrospectivo, realizado en la unidad de gastroenterología de la Clínica Fundadores. Se incluyeron pacientes adultos mayores de 18 años que hubieran recibido tratamiento con inyección local con lidocaína al 2 % sin epinefrina y que hubieran respondido una encuesta telefónica para evaluar la intensidad del dolor en una escala análoga. Resultados: se identificaron 360 elegibles y, finalmente, atendieron la entrevista telefónica 324 pacientes (90 %). El 87 % era de sexo femenino. La edad promedio de la población era de 57 años. En la preinfiltración el dolor promedio era 8,7 puntos. En la postinfiltración los pacientes tuvieron una mejoría con una intensidad promedio de 2,38 (p < 0,05). En el 71 % de los pacientes la intensidad del dolor en el seguimiento hasta 2 años tuvo una intensidad promedio de 1,65 (p < 0,05), que representa una mejoría del 81 % en la intensidad (p = 0,001). La fibromialgia tuvo una asociación positiva con la mejoría sostenida del dolor (p = 0,008). Conclusiones: en los pacientes con DCPA, la infiltración de la pared con anestesia local produce una respuesta sostenida hasta 2 años después del tratamiento.


Abstract Introduction: Chronic abdominal pain is frequently encountered at outpatient clinics where the traditional approach is to investigate visceral pathologies. Fifty percent of these patients are finally found to have abdominal wall pain which is generally secondary to entrapment of the anterior cutaneous nerve. This entity is identified by Carnett's sign. The treatment of choice is to infiltrate the painful points with lidocaine following which there is significant improvement in 85% to 90% of these patients. The duration of post-infiltration improvement is unknown. The objective of this work is to determine sustained response in one and two-year follow-up examinations. Materials and Methods: This is a retrospective cohort study conducted in the gastroenterology unit of the Clínica Fundadores. We included adult patients over 18 years of age who had received local injection treatment with 2% lidocaine without epinephrine and who had answered a telephone survey to assess the intensity of pain on an analogous scale. Results: Of the 360 eligible patients identified, 324 patients (90%) were interviewed by telephone. The average age of those interviewed was 57 years, and 87% were women. The average pain level prior to infiltration was 8.7 points. Following infiltration, the average intensity was 2.38 points (p <0.05). In 71% of patients, average pain intensity at a two year follow-up examination was 1.65 points (p <0.05), an 81% improvement in intensity (p = 0.001). Fibromyalgia had a positive association with sustained improvement in pain (p = 0.008). Conclusions: Infiltration of the abdominal wall with a local anesthetic produces a sustained response for up to two years in patients with chronic abdominal wall pain.

RESUMO

Resumen En pacientes sin una causa clara de sangrado gastrointestinal luego de una endoscopia digestiva alta y baja, la causa se encontrará en el intestino delgado hasta en el 77 % de los casos. Ante el excelente rendimiento diagnóstico de la videocápsula endoscópica (VCE) para el estudio de este segmento del tracto gastrointestinal, surge la duda de si debería ser el método diagnóstico inicial de este grupo de pacientes con posible sangrado del intestino delgado (PSID) o si la realización de una nueva endoscopia alta y baja o algún método alternativo de estudio del intestino delgado debería serlo. En esta revisión se evalúa y evidencia el rendimiento diagnóstico superior y la mayor seguridad de la VCE como abordaje inicial de pacientes con PSID en relación con otros métodos. Sin embargo, se pone en tela de juicio la mejor costo-efectividad de este abordaje en nuestro medio, que en otros ha sido claramente demostrada.


Abstract When neither upper nor lower gastrointestinal endoscopy can find a clear cause of gastrointestinal bleeding, it will eventually be found in the small intestine in up to 77% of cases. Given the excellent diagnostic performance of video capsule endoscopy for studying this segment of the gastrointestinal tract, the question of whether it should become the initial diagnostic method for patients with possible bleeding from the small intestine arises. The alternatives are to perform additional upper and lower endoscopic procedures or to use some alternative method of studying the small intestine. This review documents and evaluates the superior diagnostic performance and greater safety of videocapsule endoscopy as the initial approach for possible bleeding from the small intestine and compares it with other methods. However, the cost-effectiveness of this approach, clearly demonstrated elsewhere, is questioned in our setting.
