[Recommendations based on the management of patients with Crohn disease in the Peruvian context. Position paper of the Association for the Study of the Intestine (ASPEIN)]. / Recomendaciones basadas en el manejo de pacientes con diagnóstico de enfermedad de Crohn en el contexto peruano. Documento de posición de la Asociación Peruana para el Estudio del Intestino (ASPEIN).

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract whose etiology is unknown, which can transmurally affect any segment of the intestine and/or the perineal region. Worldwide, the incidence of inflammatory bowel disease has increased in recent decades, and the same upward trend can be seen in South America. At national level, there are no official data, however, the increase in the number of publications in the last 20 years confirms this upward trend. Crohn's disease is a forgotten disease and does not have implemented clinical guidelines based on evidence that contribute to clinicians in decision making. In this sense, the Peruvian Association for the Study of the Intestine considers the preparation of this document relevant and timely. clinical contextualized for Peru.

[Severe gastroparesia associated with the use of GLP-1 receptor agonists for weight loss]. / Gastroparesia severa asociada al uso de agonistas del receptor GLP-1 para bajar de peso.

Initially developed as medications for diabetes mellitus, GLP-1 agonists have gained much popularity in the treatment of obesity and weight loss. The present case describes a 69-year-old woman with a history of peptic ulcer and use of NSAIDs, who presented with abdominal pain and oral intolerance refractory to conventional management, for which an upper digestive endoscopy was performed, diagnosing severe gastroparesis. Asking more about the story, revealed surreptitious use of semaglutide. She continued with supportive therapy and the symptoms resolved spontaneously. The present case report aims to warn of the potential risks of the use of GLP-1 analogues in the context of endoscopy with sedation.

Gastroparesia severa asociada al uso de agonistas del receptor GLP-1 para bajar de peso / Severe gastroparesia associated with the use of GLP-1 receptor agonists for weight loss

RESUMEN Inicialmente desarrollados como medicamentos para la diabetes mellitus, los agonistas GLP-1 han ganado mucha popularidad en el tratamiento de la obesidad y la pérdida de peso. El presente caso describe a una mujer de 69 años con antecedente de úlcera péptica y consumo de AINES, quien cursó con dolor abdominal e intolerancia oral refractaria al manejo convencional, por lo que se realizó una endoscopía digestiva alta, diagnosticándose gastroparesia severa. Al ampliar la anamnesis, se reveló el uso subrepticio de semaglutida. Se continuó con terapia de soporte y los síntomas remitieron espontáneamente. El presente reporte de caso tiene como objetivo advertir los riesgos potenciales del uso de análogos de GLP-1 en el contexto de una endoscopía con sedación.

[Diphyllobotrium Spp. as a cause of chronic diarrhea diagnosed only by colonoscopy or capsule endoscopy]. / Diphyllobotrium Spp. como causa de diarrea crónica diagnosticada solo por colonoscopia o c ápsula endoscópica.

We present two patients with chronic diarrhea, with multiple negative studies, both had in common vitamin B12 deficiency. Both patients had multiple studies of parasites in negative stool. Only after colonoscopy in the first case and capsule endoscopy in the second case, it was possible to diagnose the adult forms of Diphyllobotrium spp. After treatment, both patients completely resolved their symptoms.

Diphyllobotrium Spp. como causa de diarrea crónica diagnosticada solo por colonoscopia o cápsula endoscópica

Se presentan dos pacientes con diarrea crónica, con múltiples estudios negativos, y que tenían en común la deficiencia de vitamina B12. Ambos pacientes tenían estudios repetitivos de parásitos en heces negativos. Sólo al realizarse colonoscopía en el primer caso y la cápsula endoscópica en el segundo, se pudo diagnosticar formas adultas de Diphyllobotrium spp. Luego del tratamiento antiparasitario, ambos pacientes remitieron completamente sus síntomas.

[Single balloon enteroscopy in the management of small bowel pathology. Experience of the Small Bowel Unit - British American Hospital from December 2012 to December 2018]. / Enteroscopia asistida por balón simple en el manejo de la patología del intestino delgado. Experiencia de la Unidad de Intestino Delgado de la Clínica Anglo Americana durante el periodo de diciembre del 2012 a diciembre del 2018.

Objetive: To describe our experience with single balloon enteroscopy in the management of small bowel disease in British American Hospital, Lima - Perú. MATERIAL AND METHODS: Descriptive and prospective study. We include all patients that come to perform a single balloon enteroscopy in small bowel unit of British American Hospital within December 2012 to December 2018. RESULTS: We performed 80 procedures of single balloon enteroscopy, 49 were done by oral approach, 31 by rectal approach. Mean age were 60.78 years-old (20 - 88 years). 48 patients (60%) were male. The mean insertion time for oral approach was 80 minutes (55-141 minutes), and for rectal approach was 110 minutes (55-180 minutes). The main indication for single balloon enteroscopy was obscure gastrointestinal bleeding. 6 enteroscopies were performed in patients with altered surgical anatomy (7.5%). 70 of 80 procedures (87.5%) were performed with gastroenterology-administered sedation, using midazolam, pethidine and propofol, without any respiratory or hemodinamic complication. Diagnostics achieved by single balloon enteroscopy were small bowel angiodysplasias (20%), yeyuno ileal ulcers (17.5%) and small bowel neoplasia (7.5%). Paralytic ileus was the most common complication of single balloon enteroscopy, 2 cases, and both cases were associated after no using carbon dioxide insufflation during procedure. CONCLUSION: Obscure gastrointestinal bleeding was the main indication for single balloon enteroscopy. Diagnostics achieved by single balloon enteroscopy were small bowel angiodysplasias (20%), yeyuno ileal ulcers (17.5%) and small bowel neoplasia (7.5%). Paralytic ileus was the most common complication of single balloon enteroscopy, 2 cases, and both cases were associated after no using carbon dioxide insufflation during procedure.

Objetivo: Describir la experiencia en el uso de la enteroscopia asistida por balón simple para el diagnóstico y manejo de la patología del intestino delgado en pacientes con anatomía normal y alterada por cirugía en la Clínica Anglo Americana. Material y método: El presente es un estudio descriptivo - retrospectivo que incluye a todos los pacientes que acudieron a la Unidad de Intestino Delgado de la Clínica Anglo Americana, para realizarse una enteroscopia asistida por balón durante el periodo comprendido entre diciembre del 2012 a diciembre del 2018. Resultados: Se realizaron 80 procedimientos de enteroscopia asistida por balón simple, 49 fueron realizados por via anterógrada y 31 por vía retrógrada. La edad promedio fue 60,78 años (20 a 88 años). 48 pacientes (60%) eran varones. El tiempo de inserción media fue 80 minutos para la vía anterógrada (55 - 141 minutos) y 110 minutos para la vía retrógrada (55 -180 minutos). La principal indicación para realizar la enteroscopia por balón simple fue hemorragia digestiva oscura, 45 casos (56,25%). Se realizaron 6 estudios de enteroscopias asistida por balón en pacientes con anatomía alterada (7,5%). Setenta de los ochenta procedimientos (87,5%) fueron realizados con sedación administrada por enfermería supervisada por gastroenterólogo en base a midazolam, petidina y propofol, no se presentó ninguna complicación respiratoria o hemodinámica. Los diagnósticos obtenidos más frecuentes por enteroscopia fueron: angiodisplasias de intestino delgado (20%), úlceras yeyuno ileales (17,5%) y neoplasias a nivel del intestino delgado (7,5%). La complicación que se presentó con más frecuencia posterior a la enteroscopia fue el íleo paralítico, 2 casos, y se asoció a no utilizar insuflación con dióxido de carbono durante el procedimiento. Conclusiones: La hemorragia digestiva oscura fue la principal indicación para realizar una enteroscopia asistida por balón simple. Los diagnósticos más frecuentes fueron angiodisplasias, úlceras yeyuno ileales y neoplasias a nivel del intestino delgado. La complicación más frecuente fue el íleo paralítico y se asoció a no utilizar insuflación con dióxido de carbono durante el procedimiento.
