Síndrome post-colecistectomía: análisis de una cohorte prospectiva / Post-cholecystectomy syndrome: Descriptive analysis of a prospective cohort

Introducción. El síndrome post-colecistectomía fue descrito hace más de 70 años y se define como la presencia de síntomas gastrointestinales que pueden persistir después de la colecistectomía o aparecer como nuevos síntomas. Este síndrome, poco conocido, puede manifestarse desde pocos meses hasta varios años luego de la cirugía y ocurre entre 5 % y 40 % de los pacientes. Método. Estudio de cohorte prospectiva, que incluyó pacientes a quienes se les realizó colecistectomía laparoscópica en tres unidades quirúrgicas de Bogotá, D.C., Colombia, durante un período de ocho meses, con seguimientos periódicos durante dos años. El síndrome post-colecistectomía se definió como la presencia de al menos un síntoma gastrointestinal a partir del primer mes de la cirugía. Resultados. Se incluyeron 380 pacientes de los cuales 183 (48,2 %) desarrollaron el síndrome. La edad tuvo diferencia estadísticamente significativa entre aquellos que lo desarrollaron y los que no (p=0,024). La diarrea fue el único síntoma preoperatorio asociado al desarrollo del síndrome. El síndrome post-colecistectomía se encontró en el 42,1 % de los pacientes al primer mes de seguimiento y en el 17,4 % al segundo año. Conclusiones. El síndrome post-colecistectomía ocurre en un porcentaje importante de pacientes. En concordancia con la literatura, se encontró que la diarrea prequirúrgica es un factor de riesgo independiente para el desarrollo del síndrome. Se recomienda un adecuado seguimiento de los pacientes después de una colecistectomía

Introduction. Post-cholecystectomy syndrome (PCS) was described more than 70 years ago and is defined as the presence of gastrointestinal (GI) symptoms that may persist after cholecystectomy or can present as new symptoms. This little-known syndrome can appear from a few months to several years after surgery and occurs between 5% and 40% of patients. Method. Prospective cohort study, which included patients who underwent laparoscopic cholecystectomy in three surgical units in Bogotá, Colombia, during a period of eight months, with periodic follow-up for two years. PCS was defined as the presence of at least one GI symptom from the first month after surgery. Results. Three-hundred and eighty patients were included, of which 183 (48.2%) developed the syndrome. Age had a statistically significant difference between those who developed PCS and those who did not (p=0.024). Diarrhea was the only preoperative symptom associated with the development of PCS. Post-cholecystectomy syndrome was found in 42.1% at the first month of follow-up and in 17.4% at the second year. Conclusions. Post-cholecystectomy syndrome occurs in a significant percentage of patients. Consistent with the literature, preoperative diarrhea was found to be an independent risk factor for the development of the syndrome. Adequate follow-up of patients after cholecystectomy is recommended

Pancreatitis aguda: Puntos clave. Revisión argumentativa de la literatura / Acute pancreatitis: Key points. Argumentative review of the literature

Introducción. La pancreatitis aguda es una condición gastrointestinal común que se asocia a una importante morbimortalidad. Se estima que su incidencia es de 34 por cada 100.000 habitantes, afecta principalmente a adultos a partir de la sexta década de la vida y en nuestra región es debida en la mayoría de los casos a cálculos biliares. Métodos. Se hizo una revisión de los aspectos fundamentales de esta patología, común y potencialmente mortal. Resultados. El diagnóstico requiere del hallazgo de manifestaciones clínicas, aumento de las enzimas pancreáticas en suero y, en ocasiones, el uso de imágenes diagnósticas. Se puede clasificar en leve, moderada y severa, lo cual es fundamental para determinar la necesidad de tratamiento y vigilancia en una unidad de cuidados intensivos. Conclusión. En la actualidad los pilares de manejo de la pancreatitis aguda son la terapia temprana con líquidos, tratamiento del dolor, inicio precoz de la vía oral y resolución del factor etiológico desencadenante. En presencia de complicaciones o un curso severo de enfermedad, pueden requerirse manejo antibiótico e intervenciones invasivas

Introduction. Acute pancreatitis is a common gastrointestinal condition that is associated with significant morbidity and mortality. It is estimated that its incidence is 34 per 100,000 inhabitants, it mainly affects adults from the sixth decade of life, and in our region, most of the cases are secondary to gallbladder stones. Methods. We present a review of the fundamental aspects of this disease, common and potentially fatal. Results. Diagnosis requires finding clinical manifestations, increased serum pancreatic enzymes, and sometimes the use of diagnostic imaging. It can be classified as mild, moderate and severe, which is essential to determine the need for treatment and monitoring in an intensive care unit. Conclusion. Currently, the pillars of management of acute pancreatitis are early fluid therapy, pain management, early oral food intake, and resolution of the etiology. In the presence of complications or a severe course of the disease, antibiotic management and invasive interventions may be required

Causa rara de dolor abdominal recurrente; coexistencia del síndrome de Wilkie y el síndrome del cascanueces / A rare cause of recurrent abdominal pain; the coexistence of Wilkie's syndrome and nutcracker syndrome

El síndrome del cascanueces es un síndrome que presenta síntomas clínicos como hematuria, proteinuria ortostática, congestión pélvica, varicocele del lado izquierdo, hipertensión y dolor en fosa renal. Estos síntomas se producen por la compresión de la vena renal izquierda entre la aorta y la arteria mesentérica superior. En el síndrome de Wilkie, la tercera porción del duodeno está comprimida entre la arteria mesentérica superior y la aorta abdominal, lo que provoca diversos síntomas gastrointestinales. La coexistencia de estos dos síndromes constituye una afección rara y se incluye como casos clínicos en la bibliografía. En este artículo, se presentan los resultados clínicos y radiológicos de un paciente de 17 años que presentaba dolor abdominal recurrente debido al síndrome de Wilkie, acompañado del síndrome del cascanueces que le provocaba proteinuria, por lo que el paciente fue derivado a los consultorios externos de reumatología pediátrica con un diagnóstico preliminar de fiebre mediterránea familiar.

Nutcracker syndrome is a syndrome that has clinical symptoms such as hematuria, orthostatic proteinuria, pelvic congestion, left-sided varicocele, hypertension, and flank pain. These symptoms occur because of the compression of the left renal vein between the aorta and the superior mesenteric artery. In Wilkie's syndrome, the third part of the duodenum is compressed between the superior mesenteric artery and the abdominal aorta, causing various gastrointestinal symptoms. The coexistence of these two syndromes is a rare condition and is included as case reports in the literature. This article presents the clinical and radiological results of a 17-year-old male patient who had recurrent abdominal pain due to Wilkie's syndrome, which was accompanied by nutcracker syndrome that caused proteinuria, and for this reason, the patient was referred to the Pediatric Rheumatology outpatient clinic with a preliminary diagnosis of familial Mediterranean fever.

Hidatidosis esplénica gigante primaria en una gestante: reporte de caso / Primary giant splenic hydatid disease in a pregnant woman: case report

La hidatidosis es considerada en la actualidad como un problema de salud pública en el Perú. Es una infección parasitaria trasmitida por la ingesta de huevos de Echinococcus granulosus y los órganos más comprometidos son el hígado y los pulmones, siendo rara la afectación del bazo. Presentamos el caso de una gestante joven con dolor abdominal y sensación de masa en hipocondrio izquierdo. El estudio ecográfico reveló imagen quística multitabicada en hemiabdomen izquierdo, con feto viable. Se le realizó cesárea, seguido de laparotomía exploratoria y se halló una tumoración gigante de bazo que, según el estudio anatomopatológico corresponde a una hidatidosis esplénica multiquística. Asimismo, como complicación fetal ocurrió restricción del crecimiento intrauterino. La paciente evolucionó favorablemente sin recurrencia de focos hidatídicos, mientras que el neonato mostró un patrón de crecimiento adecuado.

Hydatidosis is currently considered a public health problem in Peru. It is a parasitic infection transmitted by the ingestion of eggs of Echinococcus granulosus. The most involved organs are the liver and lungs, with spleen involvement being rare. We present the case of a young pregnant woman with abdominal pain and a sensation of mass in the left hypochondrium. The ultrasound study revealed a multiloculated cystic image in the left hemiabdomen, and a viable fetus. She underwent cesarean section, followed by exploratory laparotomy, which revealed a giant spleen tumor that, according to the anatomopathological study, corresponded to multicystic splenic hydatid disease. Likewise, intrauterine growth restriction was found as a fetal complication. The patient progressed favorably without recurrence of hydatid foci and the neonate had an adequate growth pattern.

Hernia vesical inguinoescrotal incarcerada: manejo quirúrgico / Incarcerated inguinoscrotal bladder hernia: surgical management

RESUMEN La hernia vesical es una entidad asociada a la hernia inguinal, con predisposición de lado derecho, en un porcentaje de 0,5 a 3%, hasta 10% en hombres, y a partir de la quinta a séptima década de vida1. La mayoría son pequeñas; la fisiopatología más común es la obstrucción mientras que la hiperplasia prostática es la principal etiología. La presentación clínica es poco específica, y el diagnóstico es en la mayoría de los casos transoperatorio. Se presenta el caso de un paciente de género masculino de 64 años, con antecedente patológico de enfermedad de Parkinson, hernia inguinal izquierda reducible hace 5 años. Acudió a consulta médica por manifestar dolor abdominal de moderada intensidad, más aumento de volumen en región inguinoescrotal izquierda. Al realizar el examen físico se constató una hernia inguinoescrotal izquierda no reducible. Con el diagnóstico de hernia inguinal incarcerada se realizó una exploración quirúrgica, con hallazgos de hernia inguinoescrotal de gran tamaño con contenido vesical y epiplón incarcerado con cambios de coloración. Se realizó entonces la reparación de la hernia. La evolución posoperatoria fue satisfactoria sin complicaciones.

ABSTRACT Bladder hernia is a condition associated with inguinal hernia, usually right-sided, in 0.5 to 3% of the cases and up to 10% in men between the fifth and seventh decade of life. Most hernias are small; the most common pathophysiology is obstruction while prostatic hyperplasia is the main etiology. The clinical presentation is unspecific, and the diagnosis is usually made during surgery. We report the case of a 64-year-old male patient with a history of Parkinson's disease and reducible left inguinal hernia 5 years before, who sought medical advice due to abdominal pain of moderate intensity, with increased volume in the left inguinoscrotal region.On physical examination a diagnosis of left-sided non-reducible inguinoscrotal hernia was made. With the diagnosis of incarcerated inguinal hernia the patient underwent surgical exploration which showed a large inguinoscrotal hernia containing the bladder and incarcerated omentum with color changes. The hernia was repaired, and the patient evolved with favorable outcome.

Pancreatitis aguda asociada a infección por SARS-CoV-2. Apropósito de un caso / Acute pancreatitis associated with SARS-CoV-2 infection. Acase report

El nuevo virus del SARS-CoV-2 y su enfermedadCOVID-19 ha representado un desafío para los clínicos,afectando distintos órganos y sistemas. Aunque la gravedadde la infección viene determinada sobre todo por la apariciónde neumonía grave y dificultad respiratoria aguda, se handescrito otras afectaciones en distintos aparatos y sistemas,como la sintomatología gastrointestinal, pancreática y biliar. Elcompromiso pancreático está poco descrito, con escasos reportesen la literatura a nivel mundial, siendo registrado actualmenteen más de 20 países. En este documento, se presenta un casode pancreatitis aguda donde se destaca la nueva posibilidad deasociación al COVID-19. Se trata de paciente de 17 años, desexo femenino, con antecedente de un puerperio tardío, sinhaber tenido contacto con personas confirmadas o sospechosasde COVID-19, ni viajes al extranjero. En vista de la evolucióntórpida de la paciente, se realiza tomografía axial computarizadade abdomen y pelvis donde se reportan los siguientes hallazgos:liquido peri pancreática, vesícula distendida con liquido perivesicular, liquido libre en fondo de saco e interesas. Al realizarlaparotomía exploradora se evidencia necrosis pancreática conlicuefacción en toda su extensión con esteato necrosis en epiplónmayor. Posterior al tratamiento, la paciente evolucionó afebril,con mejoría de la tolerancia oral, sin dolor abdominal, consintomatología respiratoria leve, sin requerir oxígeno en ningúnmomento, completando un total de 21 días de antibioticoterapiaempírica biasociada(AU)

e new SARS-CoV-2 virus and its diseaseCOVID-19 have posed a challenge to clinicians, affectingdifferent organs and systems. Although the severity of theinfection is mainly determined by the occurrence of severepneumonia and acute respiratory distress, other involvementin different organs and systems has been described, suchas gastrointestinal, pancreatic and biliary symptomatology.Pancreatic involvement is poorly described, with few reportsin the literature worldwide, being currently registered in morethan 20 countries. In this paper, a case of acute pancreatitisis presented, highlighting the new possibility of associationto COVID-19. e patient is 17 years old, female, with ahistory of a late puerperium, without having had contact withpeople confirmed or suspected of having COVID-19, or travel abroad. In view of the patient's torpid evolution, a computedaxial tomography of the abdomen and pelvis was performed,where the following findings were reported: peri pancreaticfluid, distended gallbladder with peri vesicular fluid, free fluid inthe cul-de-sac and interstitium. On performing an exploratorylaparotomy, pancreatic necrosis with liquefaction in all itsextension with steato necrosis in the greater omentum wasevidenced. Aer treatment, the patient evolved afebrile, withimproved oral tolerance, without abdominal pain, with mildrespiratory symptoms, without requiring oxygen at any time,completing a total of 21 days of empirical antibiotic therapy(AU)

Hernia obturatriz: Aspectos clínicos, imagenológicos y tratamiento / Obturator hernia: Clinical, imaging and treatment aspects

Introducción. Debido a la rareza de la hernia obturatriz y la imposibilidad para desarrollar estudios controlados de alto grado de evidencia, la mayoría de la literatura al respecto proviene de reportes de casos. Lo anterior, aunado al poco conocimiento del área anatómica de presentación y el cuadro clínico, la convierte en la hernia con mayor mortalidad. Métodos. Se realizó una búsqueda de la literatura en las principales bases de datos, ilustrado con pacientes manejados en el Servicio de Cirugía general de la Clínica Santa María de Sincelejo, Colombia. Discusión. La hernia obturatriz se puede descubrir en mujeres ancianas con antecedentes de cirugía abdominal o multiparidad. El signo de Howship­Romberg, que se presenta en la mitad de los pacientes, puede acompañarse de dolor abdominal en hipogastrio, vómitos y distensión progresiva. La radiografía de abdomen simple muestra tardíamente niveles hidroaéreos con ausencia de gas en ampolla rectal, pero como es poco específica para demostrar el sitio de obstrucción, es preferible la Tomografía computarizada. Conclusión. La hernia obturatriz requiere alto índice de sospecha, que ayude a la detección temprana e intervención quirúrgica inmediata, para evitar las complicaciones.

Introduction. Due to the rarity of the obturator hernia and the impossibility to develop controlled studies with a high degree of evidence, most of the reference in the literature comes from case reports. This, coupled with little knowledge of the anatomical area of presentation and clinical picture, makes it the hernia with the highest mortality. Methods. A literature search was carried out in the main databases, illustrated with patients managed in the General Surgery Service of the Clínica Santa María de Sincelejo. Discussion. Obturator hernia can be discovered in elderly women with a history of abdominal surgery or multiparity. The Howship ­ Romberg sign occurs in half of the patients, it can be associated with lower abdominal pain, vomiting, and progressive distension. Plain abdominal X-ray shows delayed air-fluid levels with absence of gas in the rectal ampulla, but since it is not very specific to demonstrate the site of obstruction, computed axial tomography is preferable. Conclusion. Obturator hernia requires a high index of suspicion, which helps early detection and immediate surgical intervention, to avoid complications.

Colitis eosinofílica asociada a enfermedad inflamatoria intestinal / Eosinophilic colitis associated with inflammatory bowel disease

INTRODUCCIÓN: La colitis eosinofílica y la colitis de la enfermedad inflamatoria intestinal, son dos entidades que pueden compartir similares características clínicas, endoscópicas y terapéuticas pero diferentes criterios diagnósticos. OBJETIVOS: Describir el caso clínico de un niño preescolar con antecedente de alergia alimentaria, de hospitalizaciones y uso de antibióticos por varias ocasiones, que evoluciona con diarrea crónica intermitente. CASO CLÍNICO: Se trata de un paciente masculino, de 3 años 5 meses, con antecedente de alergia alimentaria con cuadro crónico de dolor abdominal, diarrea y retraso en el crecimiento. Se realiza abordaje de diarrea crónica. RESULTADOS: Con hallazgos clínicos de enfermedad inflamatoria intestinal y descripción histopatológica de colitis eosinofílica, se considera la asociación entre estas dos patologías sin dejar la posibilidad de que esta última se trate de una fase inicial de enfermedad inflamatoria intestinal. CONCLUSIONES: El tratamiento de pacientes con colitis eosinofílica complicada es similar a la enfermedad inflamatoria intestinal, se requiere seguimiento clínico, endoscópico e histopatológico de pacientes con colitis eosinofílica a largo plazo.

INTRODUCTION: Eosinophilic colitis and inflammatory bowel disease colitis are two entities that may share similar clinical, endoscopic and therapeutic features but different diagnostic criteria. OBJECTIVES: To describe the clinical case of a preschool child with a history of food allergy, hospitalizations and use of antibiotics for several occasions, who evolves with chronic intermittent diarrhea. CLINICAL CASE: This is a male patient, 3 years 5 months old, with a history of food allergy with chronic abdominal pain, diarrhea and growth retardation. Chronic diarrhea was approached. RESULTS: With clinical findings of inflammatory bowel disease and histopathological description of eosinophilic colitis, the association between these two pathologies is considered without leaving the possibility that the latter is an initial phase of inflammatory bowel disease. CONCLUSIONS: The treatment of patients with complicated eosinophilic colitis is similar to inflammatory bowel disease, clinical, endoscopic and histopathological follow-up of patients with eosinophilic colitis is required in the long term.

Adenocarcinoma de apéndice, un diagnóstico diferencial en pacientes con dolor abdominal. Reporte de caso / Adenocarcinoma of the Appendix, a Differential Diagnosis in Patients with Abdominal Pain. Case Report / Adenocarcinoma do apêndice, diagnóstico diferencial em pacientes com dor abdominal. Relato de caso

Introducción. El dolor abdominal agudo es una causa frecuente de consulta en los servicios de urgencias. Su incidencia es alrededor del 5%, de los cuales el 10%- 25% de los pacientes requieren tratamiento quirúrgico. Las neoplasias apendiculares primarias son infrecuentes, actualmente representan 1% de las neoplasias malignas de origen gastrointestinal. Existe un predominio en mujeres y se debe sospechar en pacientes con factores de riesgo. El objetivo es entender la importancia del diagnóstico oportuno en el abordaje del paciente con dolor abdominal agudo. Presentación del caso. Mujer con cuadro clínico de 5 días de dolor abdominal, con hallazgo en tomografía de abdomen de marcada dilatación quística del apéndice cecal con calcificaciones lineales y nodulares en la pared y su interior. Intraoperariamente, se realizó hemicolectomía derecha con resultado histológico de neoplasia mucinosa del apéndice (adenoma serrado) con pérdida de la muscularis mucosae, catalogándolo como adenocarcinoma de bajo grado. Discusión. Los tumores apendiculares representan el 1% de las neoplasias malignas de origen gastrointestinal, son un hallazgo incidental (0.7-1.4%) en los procedimientos de apendicectomía. El diagnóstico es histopatológico y el pronóstico se relaciona con la clasificación. Es importante conocer, identificar y sospechar esta patología dada su infrecuencia, con lo cual se puede mejorar el pronóstico en los pacientes. Conclusión. Los tumores apendiculares son infrecuentes, los cuales deben ser incluidos en el grupo de patologías causantes de dolor abdominal agudo.

Introduction. Acute abdominal pain is a frequent cause of consultation to emergency services. Its incidence is about 5%, of which 10%-25% of patients require surgical treatment. Primary appendiceal neoplasms are infrequent. They currently represent 1% of malignant neoplasms of gastrointestinal origin. They are predominant in women and must be suspected in patients with risk factors. The objective is to understand the importance of timely diagnosis in approaching patients with acute abdominal pain. Case report. A woman with clinical condition of 5 days of abdominal pain. Marked cystic dilation of the cecal appendix with linear and nodular calcifications on its wall and interior found in a tomography of the abdomen. Intraoperatively, a right hemicolectomy was performed with a histological result of mucinous neoplasm of the appendix (serrated adenoma) with loss of the muscularis mucosae, classifying it as a low grade adenocarcinoma. Discussion. Appendiceal tumors represent 1% of malignant neoplasms of gastrointestinal origin, with an incidental finding (0.7-1.4%) in appendectomy procedures. The diagnosis is histopathological, and prognosis is related to its classification. It is important to know, identify and suspect this pathology due to its infrequency, which can improve the patient's prognosis. Conclusion. Appendiceal tumors are infrequent and should be included in the group of pathologies that cause acute abdominal pain.

The value of terminal lleum intubation during colonoscopy

Abstract It is uncertain whether terminal ileum intubation should be performed routinely during colonoscopy, as there is uncertainty regarding its diagnostic value. The aim of the present study is to assess the diagnostic yield of terminal ileum intubation during colonoscopy according to indications for colonoscopy. This is a cross-sectional study in which the results of 294 total colonoscopy procedures were reviewed; ileal intubation was performed in 269 (91.49%) patients. The indications for colonoscopy, the results of ileoscopy, and the histopathological results of ileal biopsies were evaluated. A total of 54 (20%) out of 269 patients who had successful intubation into the terminal ileumshowed macroscopic abnormalities on the terminal ileum. Biopsies were positive in 4 out of 54 (7.4%); all were of Crohn disease. Two were erosions (9.5%.) and 2 were ulcers (18.8%). The two erosions were presented as abdominal pain, abdominal pain and alternating bowel motion. Those with ulcers were presented with diarrhea and perianal disease. Conclusions Considering the low diagnostic yield of ileal intubation during colonoscopy, the decision to performileoscopy or not during colonoscopy needs to bemade on a case-by-case basis. However, routine ileal intubation, brief attempts should be considered despite low diagnostic yield. (AU)

Can fecal calprotectin reflect your colonic status?

Background: Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce these long-standing complications, IBD patients are in a continuous need for early diagnosis1. Markers, such as erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP), fecal calprotectin (FC) have been widely used as noninvasive parameters for IBD monitoring. We aimed, in this current study, to evaluate the value of fecal calprotectin and other noninvasive biomarkers in predicting abnormal histologic findings in patients undergoing colonoscopy.in addition to determine the cutoff value which predict IBD2. Methods: The present prospective study included 160 patients with complaint of colicky abdominal pain with frequent diarrhea associated with mucous and infrequent bleeding per rectum for more than 6 months. They presented partial improvement with medication and recurrence once stopping the treatment These patients had been recently diagnosed with IBD at many primary healthcare centers covering the areas of the Kafrelsheikh and Zagazik governorate in the North of Egyptian Nile delta. After complete history, clinical examination, and laboratory investigation, they were referred to the IBD clinic at Kafrelsheikh University Hospital for assessment and ileocolonoscopy with biopsies. Results: There was a wide spectrum of age of the studied patients, with mean age 40.12±7.88 (minimum 18 and maximum 56 years). Regarding gender, males represented 87.5% of the studied patients. Forty percent of the patients with colonic manifestation were smokers, 57% preferred a spicy diet, and the majority had low educational level (77.5%). Forty percent had obvious blood in stool, 55% had occult blood, and raised ESR CRP occurred in 32.5% and 50%, respectively. Fecal calprotectin cutoff was>159, with sensitivity 92.8% and specificity 97.5%. Conclusions: Biomarkers (FC, ESR, CRP) can be used as noninvasive parameters for the early diagnosis and prediction of organic colonic disease. Fecal calprotectin in the IBD group revealed significant area under the curve (AUC) values and cutoff> 159, with sensitivity 92.8% and specificity 97.5%. (AU)

Case Report of a Metastatic Biliary Tract Neoplasm as an Unusual Cause of Appendicitis / Reporte de caso de neoplasia biliar metastásica como causa inusual de apendicitis

Abstract Introduction: We describe the case of a patient with appendiceal metastasis as the first manifestation of a cholangiocarcinoma. Main symptoms: Abdominal pain, jaundice, hyporexia, and choluria. Methods and results: We documented an appendiceal plastron histologically compatible with metastatic appendiceal adenocarcinoma, common hepatic duct stricture, and a suspected cholangiocarcinoma, later corroborated by endoscopic retrograde cholangiopancreatography. Conclusions: Metastatic appendiceal tumors are an infrequent and poorly studied manifestation, whereas those secondary to bile duct neoplasia have rarely been reported in the literature.

Resumen Introducción: se describe el caso de una paciente con una metástasis apendicular como primera manifestación encontrada de un colangiocarcinoma. Síntomas principales: expresado con dolor abdominal, ictericia, hiporexia y coluria. Métodos y resultados: se documentó un plastrón apendicular histológicamente compatible con adenocarcinoma apendicular metastásico, estrechez del conducto hepático común, con alta sospecha de colangiocarcinoma, corroborado luego con la realización de una colangiopancreatografía retrógrada endoscópica. Conclusiones: los tumores apendiculares metastásicos son una presentación infrecuente y poco estudiada, donde los secundarios a neoplasia de vía biliar se han reportados de forma muy escasa en la literatura.

Disseminated Abdominal Echinococcosis: Case Report / Equinococosis abdominal diseminada: reporte de caso

Abstract We describe a case of disseminated abdominal hydatid disease in a 21-year-old man who presented with clinical symptoms of persistent abdominal pain after abscess drainage post-appendectomy. The images showed multiple cystic lesions in the peritoneum, liver, and spleen. Due to pain exacerbation, the patient was taken to laparotomy. Multiple cystic lesions scattered throughout the abdominal cavity were observed, which were diagnosed by histopathology as multiple cystic lesions due to peritoneal and abdominal echinococcosis.

Resumen Se realiza la descripción de un caso de hidatidosis abdominal diseminada de un hombre de 21 años, quien consultó por cuadro clínico de dolor abdominal persistente después de un drenaje de absceso luego de una apendicetomía. Las imágenes mostraron múltiples lesiones quísticas en peritoneo, hígado y bazo. Por exacerbación del dolor, el paciente se lleva a laparotomía, donde se evidenciaron múltiples lesiones quísticas diseminadas en toda la cavidad abdominal, que se diagnosticaron a la histopatología como lesiones quísticas múltiples por equinococosis peritoneal y abdominal.

High prevalence of functional dyspepsia in nonalcoholic fatty liver disease: a cross-sectional study

Abstract BACKGROUND: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE: To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. DESIGN AND SETTING: Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. METHODS: We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. RESULTS: Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. CONCLUSION: FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

Abdominal pain in the female patient: A case of concurrent acute appendicitis and infected ovarian cyst

Background: Abdominal pain is a common presentation in women of child bearing age. It has a broad diagnosis that includes disorders of the gastrointestinal, gynaecological, vascular, urogenital, and pulmonary systems. It may be caused by infections, inflammatory, anatomic or neoplastic processes. Its management varies by aetiology, and accurate diagnosis is key to avoiding inappropriate treatment. In some rare instances, acute appendicitis has been shown to occur simultaneously with a variety of gynaecologic diseases, which can add to the diagnostic dilemma. Method: We report a case of concurrent acute appendicitis and infected ovarian cyst in a 49 year old P6+4A6 who presented with recurrent abdominal pain for 4 years duration. Result: She had oophorectomy and appendicectomy. She did well post operatively and was discharged to outpatient department after stitches removal. Conclusion: Abdominal pain, being from various aetiology in women of child bearing age, detail history, thorough physical examination, and necessary imaging investigations need to be done to avoid misdiagnosis and inappropriate treatment.

Comparison on the clinical characteristics of patients with Takotsubo syndrome from China and from Europe/North America / 中华心血管病杂志

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05). (3) Symptoms: chest pain (52.8% (86/163)), chest tightness (35.0% (57/163)), shortness of breath (33.1% (54/163)), dizziness (16.0% (26/163)), sweating (15.3% (25/163)), palpitations (12.3% (20/163)), syncope (9.2% (15/163)) abdominal pain/diarrhea (8.6% (14/163)), hypotension (7.4% (12/163)), and fatigue (1.2% (2/163)) were illustrated in sequence. Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01). (6) Treatment and prognosis:the applied drugs in China were listed in order as following, β-blockers (41.1% (67/163)), antiplatelet agents (37.4%(61/163)), ACEI/ARB (36.2%(59/163)), anticoagulants (27.0%(44/163)), diuretics (19.6% (32/163)), etc. Compared with Europe/North America, the ratio of antiplatelet agents, anticoagulants, statins, diuretics, and nitrates use was higher in China (P<0.05), while the use of oxygen therapy and IABP was similar (P>0.05). The hospital mortality in China was 5.5% (9/163), during 1-year follow-up the recurrence rate was 3.7% (6/163) and the mortality was 0. The prognosis was similar with that in Europe/North America. Conclusions: Compared with TTS cases in Europe/North America, TTS cases in China also occur usually in middle-aged and elderly women, most of whom have mental/physical triggers and typical imaging manifestations, followed by a low hospital mortality rate and recurrence rate.
