ABSTRACT

Abstract Tumours of the appendix are rare and tend to be diagnosed incidentally, in cases of acute appendicitis. For some authors, appendiceal neuroendocrine tumours (ANETs) are the most frequent neoplasm of the appendix, observed in 0.3% to 0.9% of cases acute appendicitis. The present is a unicentric retrospective study conducted between January 2005 and March 2017. Out of a total of 3,007 surgeries for appendiceal pathologies performed in the adult population at the hospital where the present study was conducted, there were 70 (2.33%) malignant cases, 20 (28.6%) of which were ANETs. The patients had a median age of 44 years (range: 18 to 85 years), and were predominantly women (there were 1.9 times more women than men). In 16 cases (80%), a simple appendicectomy was performed (1 patient was submitted to a right hemicolectomy later). The cases of ANETs had a good prognosis in our series: 85% of the patients are either alive today or were alive after 5 years of follow-up. Despite the fact that ANETs are described as the most frequent tumor of the appendix, this was not confirmed in our series, in which they only represented 28.6% of the cases; adenocarcinoma was the most frequent tumor (65.7%) among our sample.


Resumo Tumores do apêndice são raros, e tendem a ser diagnosticados de forma incidental, em casos de apendicite aguda. Para alguns autores, tumores neuroendócrinos do apêndice (TNEAs) são as neoplasias mais frequentes do apêndice, e são observados em 0,3 a 0,9% de todos os casos agudos de apendicite. Este é um estudo monocêntrico e retrospectivo realizado entre janeiro de 2005 e março de 2017. Entre umtotal de 3.007 cirurgias para patologias do apêndice realizadas na população adulta no hospital em que o estudo foi conduzido, houve 70 (2,33%) casos de malignidade, 20 (28,6%) dos quais eram TNEAs. Os pacientes tinham uma idade média de 44 anos (gama: 18-85 anos), e eram predominantemente mulheres (havia 1,9 vezes mais mulheres do que homens). Em 16 casos (80%), realizou-se uma simples apendicectomia (1 paciente foi submetido a uma hemicolectomia direita mais tarde). Os casos de TNEAs tiveram um bom prognóstico em nossa série: 85% dos pacientes estão vivos hoje, ou estavam após um seguimento de 5 anos. Apesar de os TNEAs serem descritos como os tumores mais frequentes do apêndice, isso não foi confirmado nesta série, na qual eles representaram apenas 28,6% dos casos; adenocarcinoma foi o tumor mais frequente (65,7%) emnossa amostra.

ABSTRACT

Resumen Balantidium coli es el único miembro de la familia Balantidiidae capaz de producir infección en seres humanos. Presentamos un caso en un hombre de 43 años que ingresa para corrección quirúrgica de hernia ventral durante la cual se realizó apendicetomía profiláctica. En el estudio histopatológico se observó apéndice cecal con arquitectura conservada, sin la presencia de apendicitis ni periapendicitis. En la luz se reconocieron estructuras grandes (aproximado de 50 μm) redondas con citoplasma amplio con vacuolas grandes, cilias periféricas y núcleos densos, los cuales correspondieron a trofozoitos de Balantidium coli.


Abstract Balantidium coli is the only member of the Balantidiiae family capable of infecting human beings. We present one in a 43 years-old male admitted for a surgical co rrection of an incisional hernia with prophylactic appendicectomy. Histopathological findings reported the cecal appendix within normal architecture, appendicitis and peri-appendicitis free. At the lumen big, rounded shape structures (aprox. 50 mm) were visible with broad cytoplasm, big vacuoles, peripheral cilia and dense nucleus, corresponding to Balantidium coli trophozoites.

ABSTRACT

Introducción: El mucocele es una dilatación apendicular por secreción mucosa secundaria a la obstrucción de la luz, su incidencia estimada es de 0,2-0,3 por ciento de todas las apendicectomías realizadas y el 8-10 por ciento de todos los tumores apendiculares. Objetivo: Presentar un caso inusual de cirugía de urgencia, con dolor abdominal en fosa ilíaca derecha, sugestivo de apendicitis aguda operado en el servicio de urgencia. Caso clínico: Paciente femenina de 32 años de edad, que consulta por dolor abdominal en fosa ilíaca derecha asociado a náuseas, con dolor a la palpación en dicha zona, defensa muscular y dolor a la descompresión brusca del abdomen, fue intervenida quirúrgicamente con el diagnóstico presuntivo apendicitis aguda. Se encuentra durante videolaparoscopia al apéndice cecal aumentado de tamaño, sin compromiso de su base, por lo cual se decide realizar laparotomía y apendicectomía convencional. La paciente fue egresada a las 48 horas de operada con evolución favorable y pendiente de resultado anatomopatológico, el cual informó mucocele apendicular. Conclusiones: El mucocele apendicular es una entidad poco frecuente, que predomina en el sexo femenino y edades entre 50 y 60 años. El tratamiento de elección es el quirúrgico(AU)

ABSTRACT

Resumen La tuberculosis gastrointestinal es una manifestación extrapulmonar poco frecuente, correspondiendo al 3% de los casos y que compromete principalmente la región ileocecal; la afectación apendicular es poco frecuente. La apendicitis tuberculosa se puede presentar como un cuadro agudo indistinguible de las otras causas de apendicitis y el diagnóstico generalmente se hace por el hallazgo histopatológico, lo que retrasa el tratamiento y puede llevar a complicaciones. El período posparto es de riesgo de una reactivación de una tuberculosis, debido a cambios en el sistema inmunológico que se manifiestan como un síndrome de reconstitución inmune. Se presenta el caso de una paciente puérpera que ingresa por un choque séptico secundario a una apendicitis perforada. La histopatología demostró una inflamación granulomatosa crónica, con posterior confirmación por biología molecular de una tuberculosis pulmonar.


Abstract Gastrointestinal tuberculosis is a rare extrapulmonary manifestation, it represents 3% of cases and mainly involves the ileocecal region; appendiceal involvement is rare. Tuberculous appendicitis can present as an acute condition indistinguishable from other causes of appendicitis and the diagnosis is generally made by histopathological finding, which delays treatment and can lead to complications. The postpartum period is at risk of a reactivation of tuberculosis, due to changes in the immune system that manifests as an immune reconstitution syndrome. We present the case of a postpartum patient admitted for septic shock secondary to perforated appendicitis, the pathology reported chronic granulomatous inflammation and subsequent confirmation by molecular technique of pulmonary tuberculosis.

ABSTRACT

Resumen Presentamos el caso de una paciente de 83 años sin antecedentes de importancia, a quien se le realizó una colonoscopia de tamización 3 h antes del inicio de la sintomatología. La paciente consultó al servicio de urgencias por presentar dolor en la fosa ilíaca derecha de 12 h de evolución. En efecto, durante el examen físico, se encontró un dolor localizado en la fosa ilíaca derecha. Ante la sospecha de una complicación relacionada con la colonoscopia, se ordenó una tomografía de abdomen, la cual mostró signos tomográficos de apendicitis. Se realizó entonces una apendicetomía por laparoscopia, sin complicaciones, pero se evidenció un apéndice cecal perforado.


Abstract We present the case of an 83-year-old patient who had no significant medical history. A screening colonoscopy had been performed three 3 hours before onset of pain in the right iliac fossa. Twelve hours later, the patient to the emergency department. Physicians suspected that the pain was a complication related to colonoscopy and ordered an abdominal CT scan which showed tomographic signs of appendicitis. A laparoscopic appendectomy was performed and removed a perforated cecal appendix without complications.

ABSTRACT

Background: Surgeons sometimes perform appendectomies during abdominopelvic surgeries for surgical conditions unrelated to the appendix. A retrospective study of the histopathological diagnoses of incidental appendectomy specimens was performed to see the value of this practice. Materials and Methods: Records of incidentally resected appendices submitted to the Histopathology Department of the University of Benin Teaching Hospital from January 2005 to December 2014 were reviewed retrospectively. Results: A total of 129 histopathological reports of incidental appendectomy were retrospectively reviewed; 67 (51.9%) of the patients were male and 62 (48.1%) were female, giving a male­female ratio of about 1.1:1. Fifty­four cases (41.9%) had histologically normal appendices, while 75 cases (58.1%) had various histopathologically demonstrable lesions ranging from acute appendicitis (the most frequent with 27%) to neoplasia (one case of mucinous adenocarcinoma). Conclusion: Significant pathology can be uncovered on histopathological examination of the clinically normal appendix. Incidental appendectomy is thus a useful procedure

ABSTRACT

ABSTRACT A 34-years-old pregnant woman admitted in the emergency unit complaining about worsening right iliac fossa pain for 2 days. Acute appendicitis was the suspected diagnosis. Laboratory exams were ordered and results were within normal limits for infectious and inflammatory aspects. Ultrasound scan revealed a pregnancy in course without alterations and a thickness of the appendix wall without inflammatory signs in the surrounding tissue. Because the suspicion of acute appendicitis remained, a magnetic resonance was done and confirmed the diagnosis of a cecal appendix lipomatosis.


RESUMO Paciente de 34 anos, do sexo feminino, grávida, chega ao pronto-socorro com queixa de dor na fossa ilíaca direita piorando nos últimos 2 dias com suspeita de apendicite aguda. Foram solicitados exames laboratoriais, que estavam dentro dos limites de normalidade para aspectos infecciosos e inflamatórios. Exame de imagem também foi solicitado, sendo a ultrassonografia o método de escolha, que revelou gravidez em curso sem alterações e espessura da parede do apêndice sem sinais inflamatórios. Ainda com suspeita de apendicite aguda, foi realizada ressonância magnética, confirmando a hipótese de lipomatose do apêndice cecal.

ABSTRACT

Objetivo: relatar o caso de uma paciente submetida a cirurgia de derivação urinária utilizando o princípio de Mitrofanoff com a técnica de Yang-Monti. Caso clínico: paciente, feminino, 26 anos, apresentou- -se com queixas de dor para realização de sondagem vesical por sequela de bexiga neurogênica subsequente a ressecção prévia de tumor medular. Após falha medicamentosa, decidiu-se pela urostomia a fim de formar um conduto cateterizável no abdome, seguindo o princípio de Mitrofanoff. Durante o ato cirúrgico, houve aposição do apêndice cecal na cúpula da bexiga objetivando anastomosar sua extremidade distal na cicatriz umbilical. Entretanto, devido à sua falta de comprimento, optou-se por alongar o conduto com um segmento intestinal remodelado pela técnica de Yang-Monti. Comentários: o princípio de Mitrofanoff com a técnica de Yang-Monti, utilizando segmentos intestinais remodelados devido à incompatibilidade do apêndice cecal, demonstrou-se segura e efetiva para o tratamento da incontinência urinária.


Objective: To report the case of a patient submitted to a urinary diversion surgery using the Mitrofanoff principle with the Yang-Monti technique. Clinical case: A 26-years-old patient presented with complaints of pain for bladder catheterization due to a neurogenic bladder sequel after previous spinal tumor resection. After drug-therapy failure, urostomy was decided to form a catheterizable conduit in the abdomen, using the Mitrofanoff principle. During the surgical procedure, the appendix of the cecal was affixed to the dome of the bladder in order to anastomosis its distal part to the umbilical scar. However, due to its lack of length, it was decided to lengthen the conduit with an intestinal segment remodeled by the Yang-Monti technique. Comments: The Mitrofanoff principle associated to the Yang-Monti technique using remodeled intestinal segments, due to the incompatibility of the cecal appendix, proved to be a safe and effective procedure for the treatment of urinary incontinence.

ABSTRACT

PURPOSE: Appendiceal tumoral lesions can occur as benign, malignant, or borderline disease. Determination of the extent of surgery through accurate diagnosis is important in these tumoral lesions. In this study, we assessed the accuracy of preoperative CT and identified the factors affecting diagnosis.METHODS: Patients diagnosed or strongly suspected from July 2016 to June 2019 with appendiceal mucocele or mucinous neoplasm using abdominal CT were included in the study. All the patients underwent single-incision laparoscopic cecectomy with the margin of cecum secured at least 2 cm from the appendiceal base. To compare blood test results and CT findings, the patients were divided into a mucinous and a nonmucinous group according to pathology.RESULTS: The total number of patients included in this study was 54 and biopsy confirmed appendiceal mucinous neoplasms in 39 of them. With CT, the accuracy of diagnosis was 89.7%. The mean age of the mucinous group was greater than that of the nonmucinous group (P = 0.035). CT showed that the maximum diameter of appendiceal tumor in the mucinous group was greater than that in the nonmucinous group (P < 0.001). Calcification was found only in the appendix of patients in the mucinous group (P = 0.012). Multivariate analysis revealed that lager tumor diameter was a factor of diagnosis for appendiceal mucinous neoplasm.CONCLUSION: The accuracy of preoperative diagnosis of appendiceal mucinous neoplasms in this study was 89.7%. Blood test results did not provide differential diagnosis, and the larger the diameter of appendiceal tumor on CT, the more accurate the diagnosis.

ABSTRACT

Abstract Introduction Crohn's Disease is a chronic and idiopathic inflammatory process with transmural invasion that can affect the entire gastrointestinal tract. The etiopathogenesis of this pathology is not fully understood and studies have been carried out to understand the influence of different kind of factors on its development, including appendectomy. This monograph aims to address the possible existence of a link between appendectomy and Crohn's Disease, and the possible causes and clinical consequences of this association. Methods This monograph was based on the research of original scientific articles in MEDLINE database via PubMed, restricted to articles in Portuguese and English during the period between 1991 and 2017. Results Appendectomy seems positively associated with the development of Crohn's Disease, especially in the first years of surgery, regardless of whether or not there is inflammation of the appendix. In fact, the appendix plays important roles in gastrointestinal integrity, acting in the development of an adequate immune response, maintaining and regulating the intestinal flora. Conclusion The appendix is important for intestinal homeostasis, preventing the development of certain pathologies. Its resection, regardless of whether or not there is an inflammation after surgery, increases the risk of Crohn's Disease and worsens the prognosis of this pathology, so appendectomy should be avoided in the absence of appendicitis.


Resumo Introdução A Doença de Crohn é um processo inflamatório crónico e idiopático com atingimento transmural que pode afetar todo o trato gastrointestinal. A etiopatogenia desta patologia não está completamente esclarecida pelo que se tem vindo a realizar estudos para perceber a influência de diferentes fatores no seu desenvolvimento, entre os quais a apendicectomia. Esta monografia visa abordar a existência de uma possível relação entre apendicectomia e Doença de Crohn e as possíveis causas e consequências clínicas desta associação. Métodos Esta monografia foi elaborada com base em artigos científicos originais pesquisados na base de dados MEDLINE via PubMed, com restrição a artigos em português e inglês com limite temporal de 1991 a 2017. Resultados A apendicectomia parece associar-se positivamente ao desenvolvimento da Doença de Crohn, principalmente nos primeiros anos após a cirurgia, independentemente de haver ou não inflamação do apêndice. De facto, o apêndice desempenha importantes funções na integridade gastrointestinal, com influência no desenvolvimento de uma resposta imunológica adequada e na manutenção e regulação da flora intestinal. Conclusão O apêndice é importante na homeostasia intestinal, prevenido o desenvolvimento de determinadas patologias. A sua ressecção, independentemente do facto de haver ou não inflamação aquando da cirurgia, aumenta o risco de Doença de Crohn e piora o prognóstico desta patologia, pelo que a apendicectomia deve ser evitada na ausência da doença.

ABSTRACT

Presentamos el caso de una paciente en edad reproductiva con dolor abdominal crónico y antecedente de endometriosis pelviana. Los estudios por imágenes muestran masa en topografía apendicular. Se decidió exploración laparoscópica programada y se realizó la resección del tumor apendicular. La anatomía patológica mostró endometriosis del apéndice cecal. Posteriormente se realiza una revisión bibliográfica de esta patología y se hacen consideraciones sobre su frecuencia, presentación clínica, hallazgos intraoperatorios, forma de estudio y posibilidades terapéuticas.


We report the case of a female patient in childbearing age with chronic pain and a history of pelvic endometriosis. The image tests showed the presence of a mass at the level of the cecal appendix. The patient underwent a scheduled diagnostic laparoscopy and the appendiceal tumor was resected. The pathological examination revealed appendiceal endometriosis. We performed a review of the literature and made considerations about its prevalence, clinical presentation, interoperative findings, diagnostic tests and therapeutic management.

ABSTRACT

La presencia del apéndice cecal en el saco de una hernia inguinal se denomina hernia de Amyand1,2. Su incidencia varía ‒según distintos autores‒ del 0,13% al 1,7%. Es una rara patología que se diagnostica intraoperatoriamente, ya que su diagnóstico preoperatorio es excepcional. No obstante, en citas bibliográficas se han descripto pocos casos de diagnóstico intraoperatorio, por lo que es importante tener la sospecha clínica en hernias incarceradas de cara al diagnóstico diferencial y a valorar la solicitud de estudios diagnóstico. Su tratamiento es la apendicectomía o reducción del apéndice cecal a la cavidad abdominal asociada a herniorrafia o hernioplastia³.


Amyand’s hernia is defined as an inguinal hernia containing the vermiform appendix1,2. This rare condition, with an incidence between 0.13% and 1.7%, is diagnosed during surgery, as the preoperative diagnosis is exceptional. Few cases of intraoperative diagnosis have been described in the literature. The diagnosis should be suspected in cases of incarcerated hernias so as to order the specific tests. The surgical management includes appendectomy or appendix reduction to the abdominal cavity associated to mesh repair or primary hernia repair without mesh³.

ABSTRACT

ABSTRACT Aim: The purpose of this review was to present and discuss the anatomical variations and congenital abnormalities of the vermiform appendix and mesoappendix reported in recent years, and their associations with acute appendicitis and other associated pathologies. Methods: The search was carried out in the following databases: PubMed, Science Direct, and SciELO. Results: Thirty-seven studies were included in this review. Among the abnormalities of the vermiform appendix identified are agenesis and duplicity, and anatomical variations were related to length and positioning. Appendicular duplicity was a more frequent abnormality, mainly Type B2, associated with acute appendicitis, followed by agenesis, Type III. The first case of agenesis associated with acute appendicitis and volvulus-type duplicity of the appendix was identified. The most frequent position was retrocecal in adults and pelvic in children. In the mesoappendix, anatomical variations in its positioning, shape, absence, and length were identified. Conclusion: This review sought to present and discuss the anatomical variations and congenital abnormalities of the vermiform appendix and mesoappendix reported in recent years, and their associations with acute appendicitis and other associated pathologies, contributing to aid in clinical diagnosis and surgical interventions in patients with suspected acute appendicitis.


RESUMO Objetivo: O objetivo desta revisão foi apresentar e discutir as variações anatômicas e anomalias congênitas do apêndice vermiforme e mesoapêndice relatados nos últimos anos e suas associações com apendicite aguda e outras patologias associadas. Métodos: A busca foi realizada nas seguintes bases de dados: Pubmed, Science Direct e Scielo. Resultados: Trinta e sete estudos foram incluídos nesta revisão. Entre as anormalidades do apêndice vermiforme identificada estão agenesia e duplicidade e, variações anatômicas relacionadas ao comprimento e posicionamento. A duplicidade apendicular foi a anormalidade mais incidente, principalmente do Tipo B2, associada à apendicite aguda, seguida de agenesia do Tipo III. O primeiro caso de agenesia associada à apendicite aguda e à duplicidade de apêndice do tipo vólvulo foi identificado. A posição mais frequente foi a retrocecal em adultos e a pélvica em crianças. No mesoapêndice, foram identificadas variações anatômicas em seu posicionamento, formato, ausência e comprimento. Conclusão: Esta revisão procurou apresentar e discutir as variações anatômicas e anomalias congênitas do apêndice vermiforme e mesoapêndice relatados nos últimos anos e suas associações com apendicite aguda e outras patologias associadas contribuindo para o auxílio no diagnóstico clínico e intervenções cirúrgicas em pacientes com suspeita apendicite aguda.

ABSTRACT

Introducción: Los tumores neuroendocrinos (TNE) son un grupo de neoplasias que se originan a partir de células enterocromafínicas, especialmente ubicadas en el tubo digestivo. El objetivo del presente estudio es escribir la distribución topográfica, el manejo multidisciplinario y diagnóstico patológico según la OMS de los tumores neuroendocrinos del tubo digestivo. Métodos: El presente es un estudio descriptivo, retrospectivo de los casos con diagnóstico anatomopatológico confirmado de tumor neuroendocrino localizados en el tubo digestivo entre enero del 2011 a diciembre del 2018 en el Instituto Oncológico Nacional del Ecuador- SOLCA de Guayaquil. Se describe topografía y tipo de tratamiento establecido con frecuencias y porcentajes. Resultados: Ingresaron al estudio 21 casos. La localización más frecuente fue el apéndice cecal n = 8 (38 %), en estómago n=4 (19 %), intestino delgado n=3 (14 %). El diagnóstico patológico en estadio G1 (65 %); G2 (24%) y G3 (12%). La primera línea de tratamiento fue la cirugía con intención curativa n=19 (90.5 %) y tratamiento endoscópico n=2 (9.5 %). Los pacientes sometidos a cirugía, n=16/19; (84 %) obtuvieron niveles de resección 0 (R0) y permanecieron en observación clínica, los demás sujetos en el estudio recibieron tratamiento adyuvante con somatostatina sola n=1 (4.8 %) o combinación de somatostatina y radioterapia n=2 (9.5 %). Conclusión: El diagnóstico de tumor neuroendocrino de tubo digestivo es una etiología oncológica poco frecuente. El tratamiento quirúrgico en esta serie de casos está enfocada en una acción curativa de tipo quirúrgico.


Introduction: Neuroendocrine tumors (NETs) are a group of neoplasms that originate from enterochromaffin cells, especially located in the digestive tract. The objective of the present study is to write the topographic distribution, the multidisciplinary management and pathological diagnosis according to the WHO of the neuroendocrine tumors of the digestive tract. Methods: This is a descriptive, retrospective study of the cases with a confirmed anatomopathological diagnosis of neuroendocrine tumor located in the digestive tract between January 2011 to December 2018 at the National Oncology Institute of Ecuador- SOLCA of Guayaquil. The topography and type of treatment established with frequencies and percentages are described. Results: 21 cases were entered into the study. The most frequent location was the cecal appendix n = 8 (38%), stomach n = 4 (19%), small intestine n = 3 (14%). The pathological diagnosis in stage G1 (65%); G2 (24%) and G3 (12%). The first line of treatment was surgery with curative intent n = 19 (90.5%) and endoscopic treatment n = 2 (9.5%). Patients undergoing surgery, n = 16/19; (84%) obtained resection levels 0 (R0) and remained under clinical observation, the other subjects in the study received adjuvant treatment with somatostatin alone n = 1 (4.8%) or combination of somatostatin and radiotherapy n = 2 (9.5%). Conclusion: The diagnosis of neuroendocrine tumor of the digestive tract is a rare oncological etiology. The surgical treatment in this series of cases is focused on a surgical action of a surgical type.

ABSTRACT

ABSTRACT Objective: To investigate how symptoms vary according to the appendiceal position in pediatric patients and to demonstrate that the laparoscopic approach is safe and effective in any appendiceal location by comparing each location to another. Methods: The medical records of 1,736 children aged 14 or younger who underwent laparoscopic appendectomy over a period of 14 years were analyzed retrospectively. Patients were divided according to the position of the appendiceal tip into four groups: anterior, pelvic, retrocecal and subhepatic. The Kruskal-Wallis and chi-square tests were used with the Bonferroni correction, with a significant p<0.05. Results: The appendiceal location was anterior in 1,366 cases, retrocecal in 248 cases, pelvic in 66 cases and subhepatic in 56 cases. There were no significant differences between the groups in terms of patient age and gender. Abdominal pain was the only symptom with statistically significant differences between the groups. The rate of perforated appendicitis was higher in the subhepatic and pelvic positions. Intraoperative complications and conversions were not statistically significant. Technical difficulties and operative time were higher in subhepatic position. The rate of postoperative complications was similar between the different locations, except for bowel obstruction, which was higher in pelvic appendicitis. Conclusions: The clinical symptoms of appendicitis hardly ever change with the position of the appendix. The laparoscopic approach is safe and effective, regardless the appendiceal location.


RESUMO Objetivo: Investigar como os sintomas variam de acordo com a posição do apêndice em pacientes pediátricos e demonstrar que a laparoscopia é segura e eficaz em qualquer posição do apêndice, comparando-as. Métodos: Os prontuários de 1.736 pacientes pediátricos com idade ≤14 anos submetidos à apendicectomia laparoscópica em um período de 14 anos foram analisados retrospectivamente. Os pacientes foram divididos de acordo com a posição do apêndice: anterior, pélvica, retrocecal e sub-hepático. Os testes de Kruskal-Wallis e do qui-quadrado foram usados com a correção de Bonferroni, sendo significante p<0,05. Resultados: A posição do apêndice era anterior em 1.366 casos, retrocecal em 248 casos, pélvica em 66 casos e sub-hepática em 56 casos. Não houve diferenças significativas entre os grupos quanto às variáveis idade e sexo. A dor abdominal foi a única variável com diferenças estatisticamente significantes entre os grupos. A taxa de apêndice perfurado foi superior nas posições sub-hepática e pélvica. As complicações intraoperatórias e a taxa de conversão não foram estatisticamente significativas. As dificuldades técnicas e o tempo cirúrgico foram superiores em posição sub-hepática. A taxa de complicações pós-operatórias foi semelhante entre as diferentes posições, exceto a obstrução intestinal, que foi superior em posição pélvica. Conclusões: Os sintomas da apendicite dificilmente variam com a posição do apêndice. A laparoscopia é segura e eficaz, independentemente da posição do apêndice.

ABSTRACT

Resumen La apendicitis aguda es una de las causas quirúrgicas de dolor abdominal más frecuentes en el mundo. Se presenta en diversos grupos etarios y su presentación clínica puede variar de un grupo a otro. Además hay una variedad de patologías crónicas que pueden opacar la sintomatología usual de la enfermedad, entre ellas la diabetes mellitus. En las últimas décadas la incidencia de diabetes mellitus se ha elevado considerablemente por lo que es más común que un paciente diabético padezca de apendicitis. También, el retraso entre el inicio de los síntomas y el diagnóstico de apendicitis, es un factor de riesgo para el desarrollo de apendicitis aguda complicada. Por ende, es importante conocer tanto las complicaciones como el impacto que puede tener la diabetes mellitus sobre la presentación clínica típica de la apendicitis aguda, para de esta manera, realizar un diagnóstico temprano y preciso.


Abstract Acute Appendicitis is one of the most common surgical causes for abdominal pain in the world. It occurs in a variety of age groups and its clinical presentation vary from one group to another. Additionally, there are several chronic conditions that can blurry the usual symptomatology of the disease, among them diabetes mellitus. In the last decades the incidence of diabetes mellitus has increased considerably, therefore it is more common for a diabetic patient to suffer from appendicitis. Also the delay between the beginning of the symptoms and the diagnosis of appendicitis is a risk factor for the development of complicated acute appendicitis. Thus it is important to know the complications and the impact that diabetes mellitus can have over the clinical presentation of acute appendicitis, thereby an accurate diagnose can be made in the shortest time possible.

ABSTRACT

Los casos de apendicitis aguda debida a cuerpos extraños es una condición muy rara, con una prevalencia de 0,0005 %, en la cual se observa un papel crucial de la obstrucción de la luz apendicular en el inicio de sintomatología. La mayoría de los cuerpos extraños que se ingieren son expulsados sin complicaciones y sin necesidad de intervención quirúrgica, observándose perforaciones en menos del 1 %. Se presenta el caso de un hombre de 25 años de edad con un cuadro clínico de apendicitis aguda que necesitaba de intervención quirúrgica, en la que se halló un cuerpo extraño (gancho 'nodriza'), con perforación proximal apendicular y peritonitis localizada


Cases of acute appendicitis due to foreign bodies are a very rare condition, with a prevalence of 0.0005%, in which an obstruction of the appendiceal lumen is seen as a crucial role in the onset of the symptomatology. The majority of ingested foreign bodies are expelled without complications with no need of surgical intervention; perforations are observed in <1% of cases. We present the case of a 25-year-old man with a clinical acute appendicitis requiring surgical intervention, where a foreign body (safety pin) with proximal appendiceal perforation and localized peritonitis was found

ABSTRACT

Acute appendicitis (AA) is one of the most common causes of acute abdominal pain, which can progress to perforation of the appendix and peritonitis. Recently, AA has been classified into uncomplicated (nonperforated, no phlegmon) or complicated (abscess, perforation, phlegmon) appendicitis, for an appropriate initial treatment. With respect to surgical treatment of AA, laparoscopic surgery has been widely accepted worldwide as a safe and feasible first-line treatment. Over the last decade, non-operative treatment has been proposed as an alternative to surgery in uncomplicated AA, and has also played an important role in the management of complicated AA. AA is also the most common cause for abdominal surgery during pregnancy, though an accurate diagnosis of AA during pregnancy is challenging. In this review, the topics being discussed include: 1) Non-operative management for uncomplicated AA, 2) Management for AA in pregnancy, 3) Management for complicated appendicitis (especially immediate laparoscopic surgery for appendiceal abscess), 4) Appendiceal neoplasms related to complicated AA.

ABSTRACT

Coin batteries are often used in daily life devices and can be easily available. Children can swallow coin batteries, resulting in the need to go to hospital, but this is rare in adults. Adults generally eliminate the swallowed coin battery from the digestive system, unless they have congenital structural abnormalities of the digestive system or complications, such as postoperative stenosis. In this case, a 31-year-old man swallowed three coin batteries, approximately 0.4 cm in diameter emergent endoscopy was unable to find any batteries embedded in the ingested food. An attempt was made to rinse out the batteries by bowel preparation. During the hospital stay, the patient complained of acute abdominal pain and fever. In the abdominal CT scan, impaction of the coin battery into the appendix was confirmed. The patient underwent a laparoscopic appendectomy to prevent appendiceal perforation.
