[The 5-5-2 criteria for biliary cannulation and post endoscopic retrograde cholangiopancreatography complications: Experience in a reference hospital, Peru]. / Criterios 5-5-2 de canulación biliar y complicaciones post colangiopancreatografía retrógrada endoscópica: Experiencia en un hospital de referencia, Perú.

The European Society for Gastrointestinal Endoscopy (ESGE) defines "difficult biliary cannulation" by the presence of one or more of the following: more than 5 contacts with the papilla, more than 5 minutes attempting to cannulate, or inadvertent cannulation of the pancreatic duct in 2 or more times (5-5-2 criteria), recommending these cut-off points to perform advanced cannulation techniques in order to reduce the rate of post-ERCP adverse events. Our objective was to evaluate the performance of the 5-5-2 criteria and their association with post-ERCP complications in a reference hospital in Peru. We performed a prospective analytical case-control study and 120 patients who underwent ERCP were enrolled. The case group included 30 patients who met at least one of the 5-5-2 criteria and the control group included 90 patients without any of these criteria. The ERCP- related complications in both groups and their association with each of the 5-5-2 criteria were compared. The ERCP-related complications that occurred were post-ERCP pancreatitis (6.6% in the case group vs. 3.3% in the control group), bleeding (3.3% controls vs. 0% cases) and perforation (1.1% controls vs. 0% cases); no statistically significant differences were observed. The criterion of 2 or more unintended cannulations to the pancreatic duct showed a significant association (OR= 10.29, CI: 1.47-71.98; p= 0.005) with the incidence of post-ERCP pancreatitis. The criteria 5 minutes and 5 attempts were not associated with post-ERCP complications. In conclusion, among 5-5-2 criteria only the unintended cannulation of 2 or more times into the pancreatic duct was associated with an increased risk of post-ERC pancreatitis. The time and number of attempts criteria could be cautiously expanded without increasing the rate of post-ERCP complications.

Criterios 5-5-2 de canulación biliar y complicaciones post colangiopancreatografía retrógrada endoscópica: Experiencia en un hospital de referencia, Perú

La Sociedad Europea de Endoscopia Gastrointestinal (ESGE) define "canulación difícil" como aquella en la que se realizan más de 5 intentos, se exceden 5 minutos, o se produce canulación inadvertida del conducto pancreático 2 o más veces (criterios 5-5-2), recomendando estos puntos de corte para realizar técnicas avanzadas de canulación y disminuir la tasa de eventos adversos post CPRE. Nuestro objetivo fue evaluar el rendimiento de los criterios 5-5-2 y su asociación con complicaciones post CPRE en un hospital de referencia de Perú. Realizamos un estudio analítico prospectivo de casos y controles en el que se incluyó 120 pacientes a los que se realizó CPRE. El grupo casos estuvo formado por 30 pacientes que cumplieron al menos uno de los criterios 5-5-2 y el grupo controles por 90 pacientes sin ninguno de estos criterios. Se comparó el desarrollo de complicaciones en cada grupo y su asociación con cada uno de los criterios 5-5-2. Las complicaciones presentadas fueron: pancreatitis post CPRE (6,6% en el grupo casos vs 3,3% en el grupo controles), sangrado (3,3% controles vs 0% casos) y perforación (1,1% controles vs 0 % casos); sin observar diferencia estadísticamente significativa. El criterio de 2 o más ingresos inadvertidos al conducto pancreático presentó asociación significativa (OR= 10,29, IC: 1,47-71,98; p= 0,005) con el desarrollo de pancreatitis post CPRE. Los criterios 5 minutos y 5 intentos no se asociaron a complicaciones post CPRE. En conclusión, el más relevante de los criterios 5-5-2 fue el ingreso inadvertido al conducto pancreático en 2 o más ocasiones, mostrando asociación por sí solo con pancreatitis post CPRE. Los criterios tiempo y número de intentos podrían ampliarse con cautela sin aumentar la tasa de complicaciones post CPRE.

[Medical and surgical management of moderate-to-severe inflamatory bowel disease]. / Manejo médico quirúrgico de la enfermedad inflamatoria intestinal moderada-severa.

The management of inflammatory bowel disease (IBD) is mainly medical, however, more than 70% of patients with Crohn's disease (CD) and 25% with ulcerative colitis (UC) will require surgery during their lifetime. OBJECTIVE: To evaluate medical, surgical management and evolution in patients with moderate-to-severe IBD. MATERIALS AND METHODS: Observational, descriptive, retrospective study from January 2011 to December 2019 in the Gastroenterology Service of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru. RESULTS: Twenty two patients with IBD, 17 with CD and 5 with UC were included. Male predominance (59%). Emergency surgery was performed in 35.2% and 60% of patients with CD and UC, respectively. Stenosis and toxic megacolon were the most frequent indications. According to the type of surgery, hemicolectomy (41%) and intestinalresection (41%) were the most frequently performed in CD, while in UC it was total colectomy (60%). Among the postoperative complications, dehiscence/fistula and intra-abdominal collections were the most frequently reported in CD; whereas in UC it was surgical site infection and adynamic ileus. After surgery, biologics and 5-ASA associated with immunomodulator were the most used treatment in CD and UC, respectively. Mortality was 17.6% in CD and 60% in UC. CONCLUSIONS: Surgical treatment is an option in the management of moderate-to-severe IBD. Emergency surgery in IBD continues to have a high morbidity and mortality rate.

Manejo de la hemorragia digestiva alta en pacientes con infección por SARS-CoV-2 en un hospital de Lima, Perú / Management of upper gastrointestinal bleeding in patients with SARS-COV-2 infection in a hospital in Lima-Peru

Resumen Introducción: la pandemia por SARS-CoV-2 ha conllevado la reestructuración de las unidades de endoscopía digestiva en el mundo, lo cual ha limitado los procedimientos endoscópicos y priorizado indicaciones de emergencia como la hemorragia digestiva alta (HDA). No obstante, existe escasa evidencia respecto a su impacto en la evolución y resultados. Objetivo: evaluar el manejo de la HDA en el contexto de la pandemia del coronavirus por SARS-CoV-2. Materiales y métodos: estudio observacional, descriptivo, retrospectivo de marzo a agosto de 2020 en pacientes con diagnóstico de HDA e infección por SARS-CoV-2. Resultados: de 4320 pacientes con infección por SARS-CoV-2, 51 presentaron HDA al ingreso. La mediana de edad fue de 70 años. El 58,8 % era de sexo masculino. El 56,9 % tenía una puntuación de Glasgow-Blatchford (SGB) ≥12. El 21,6 % requirió soporte de oxígeno. Solo 34 pacientes (66,7 %) recibieron tratamiento médico; asimismo, 17 (33,3 %) recibieron tratamiento médico más endoscopia digestiva alta (EDA); de estos, a 6 (35,3 %) se les realizó endoscopia terapéutica. La enfermedad ulcerosa péptica fue el hallazgo más frecuente. Al comparar el tipo de tratamiento recibido, no hubo diferencias significativas entre el número de transfusiones de glóbulos rojos, resangrado, reingreso por HDA, estancia hospitalaria ni mortalidad secundaria a la HDA. La mortalidad global fue del 25,4 % (13 pacientes) y se debió, principalmente, al compromiso respiratorio por SARS-CoV-2. Conclusiones: se observa una reducción en el número de EDA de emergencia por HDA en la pandemia actual, así como un tiempo mayor al estándar para su realización. Más del 80 % de los pacientes que recibieron solo tratamiento médico evolucionaron favorablemente, y solo un tercio de los pacientes a quienes se les realizó una EDA requirió terapéutica endoscópica.

Abstract Introduction: The SARS-CoV-2 pandemic has led to the restructuring of digestive endoscopy units around the world, limiting endoscopic procedures and prioritizing emergency indications such as upper gastrointestinal hemorrhage (UGH). However, there is little evidence regarding its impact on evolution and outcomes. Objective: To evaluate the management of UGH in the context of the SARS-CoV-2 coronavirus pandemic. Materials and methods: Observational, descriptive, retrospective study carried out between March and August 2020 in patients with diagnosis of UGH and SARS-CoV-2 infection. Results: Of 4 320 patients with SARS-CoV-2 infection, 51 had UGH on admission. The median age of the population was 70 years and 58.8% were male. Glasgow-Blatchford Bleeding Score (GBS) of ≥12 was obtained in 56.9%. Oxygen support was required by 21.6%. 34 (66.7%) patients received medical treatment only, while 17 (33.3%) received medical treatment plus upper gastrointestinal endoscopy (UGE), of which 6 (35.3%) underwent therapeutic endoscopy. Peptic ulcer disease was the most frequent finding. When comparing the type of treatment received, there were no significant differences between the number of red blood cell transfusions, rebleeding, re-admission due to UGH, hospital stay, or mortality secondary to UGH. Overall mortality was 25.4% (13 patients), mainly due to respiratory failure due to SARS-CoV-2. Conclusions: A reduction in the number of emergency upper gastrointestinal endoscopies for UGH was observed during the current pandemic, as well as a longer than standard time for their performance. More than 80% of patients who received medical treatment alone evolved favorably and only one third of the patients who underwent UGE required endoscopic therapy.

El tratamiento de la enfermedad inflamatoria intestinal (EII) es principalmente médico, sin embargo, más del 70% de pacientes con enfermedad de Crohn (EC) y 25% con colitis ulcerativa (CU) requerirán cirugía. Objetivos: Evaluar el manejo médico- quirúrgico y evolución en pacientes con EII moderada-severa. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo de enero del 2011 a diciembre del 2019 en el Servicio de Gastroenterología del Hospital Nacional Guillermo Almenara Irigoyen, Lima-Perú. Resultados: Se incluyó 22 pacientes con EII, 17 con EC y 5 con CU. El 59% fueron masculinos. Se realizó cirugía de emergencia en el 35,2% y el 60% de los pacientes con EC y CU respectivamente. La estenosis y el megacolon tóxico fueron las indicaciones más frecuentes. Según el tipo de cirugía, la hemicolectomía (41%) y la resección intestinal (41%) fueron las más frecuentemente realizadas en EC, mientras que, en CU fue la colectomía total (60%). Dentro de las complicaciones postquirúrgicas, las dehiscencias/fistulas y colecciones intraabdominales fueron las más frecuentemente reportadas en EC; mientras que, en CU fue la infección del sitio operatorio e íleo adinámico. Luego de cirugía, los biológicos y los 5-ASA asociados a inmunomodulador fueron el tratamiento más utilizados en EC y CU respectivamente. La mortalidad fue del 17,6% en EC y 60% en CU. Conclusiones: El tratamiento quirúrgico es una opción en el manejo de la EII moderada-severa. La cirugía de emergencia en EII continúa presentando una alta morbimortalidad.

[Clinical-pathological characteristics and endoscopic management of colonic sessile serrated lesions in a reference hospital in Lima - Peru]. / Características clínico-patológicas y manejo endoscópico de lesiones serradas sésiles de colon en un hospital de referencia en Lima - Perú.

Colorectal cancer (CRC) is one of the most frequent worldwide. Approximately one third of cases originate from the serrated pathway of carcinogenesis, with colonic sessile serrated lesions (SSL) being the main cause of interval CRC. OBJECTIVE: To evaluate the clinical, endoscopic, histological characteristics and endoscopic management of colonic LSS. MATERIALS AND METHODS: Observational, descriptive, retrospective study from July 2017 to June 2019 in the gastroenterology service of the Guillermo Almenara Irigoyen National Hospital, Lima - Peru. The characteristics of 79 LSS were evaluated, the chi-square statistic was used to analyze the association of clinical and endoscopic variables with the presence of dysplasia; and the size of the lesion with the type of endoscopic resection. RESULTS: In 74 patients, 79 SSL were found, 67 (84.8%) with dysplasia (44 high-grade and 23 low-grade). Average age of 52 years and 44 (59.4%) were males. The location in the right colon (OR=5.09, 95% CI 1.38â€"18.7, p=0.009), the size >10 mm (OR=6.13, 95% CI 1.50â€"24,94, p=0.014) and the â€Å“blurred edges†(OR=5.08, 95% CI 1.17-21.98, p=0.019), are significantly related to the presence of dysplasia. SSL smaller than 20 mm showed statistical association with bloc resection (OR=69.3, 95% CI 7.35-653.9, p <0.001) with respect to the piecemeal resection. CONCLUSIONS: The finding of SSL during colonoscopies is frequent. The location, size and finding of blurred edges are related to the presence of dysplasia. Mucosal endoscopic resection was a safe and effective technique.

Características clínico-patológicas y manejo endoscópico de lesiones serradas sésiles de colon en un hospital de referencia en Lima - Perú / Clinical-pathological characteristics and endoscopic management of colonic sessile serrated lesions in a reference hospital in Lima - Peru

RESUMEN El cáncer colorrectal (CCR) es uno de los más frecuentes a nivel mundial. Aproximadamente un tercio de los casos se originan por la vía serrada de carcinogénesis, siendo las lesiones serradas sésiles (LSS) de colon, una las principales responsables del CCR de intervalo. Objetivo: Evaluar las características clínicas, endoscópicas, histológicas y el manejo endoscópico de las LSS de colon. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo de julio del 2017 a junio del 2019 en el servicio de gastroenterología del Hospital Nacional Guillermo Almenara Irigoyen, Lima - Perú. Se evaluó las características de 79 LSS, se utilizó el estadístico chi-cuadrado para analizar la asociación de variables clínicas y endoscópicas con la presencia de displasia; y el tamaño de la lesión con el tipo de resección endoscópica. Resultados: En 74 pacientes se halló 79 LSS, 67 (84,8%) con displasia (44 de alto grado y 23 de bajo grado). Edad media de 52 años y 44 (59,4%) fueron varones. La localización en colon derecho (OR=5,09, IC 95% 1,38-18,7, p= 0,009), el tamaño >10 mm (OR=6,13/IC 95%/1,50-24,94/ p=0,014) y los "bordes borrosos" (OR=5,08, IC 95% 1,17-21,98, p=0,019), se relacionan de manera significativa con la presencia de displasia. Las LSS menores a 20 mm mostraron asociación estadística con la resección en bloque (OR=69,3, IC 95% 7,35-653,9, p<0,001) respecto a la piecemeal. Conclusiones: El hallazgo de LSS durante colonoscopías es frecuente. La localización, el tamaño y el hallazgo de bordes borrosos se relacionan con la presencia de displasia. La resección endoscópica mucosa fue una técnica segura y efectiva.
