ABSTRACT

Background: The frequency of appendicular presence of Enterobius vermicularis varies from 0.2 to 41.8 percent. It is generally a pathological finding. The luminal obstruction by the parasite may unveil an acute appendicitis. Aim: To study the frequency of Enterobius vermicularis presence in surgical pieces of appendectomies. Material and Methods: Analysis of surgical pieces of appendectomies processed at the pathology laboratory of a general hospital, between 1993 and 2010. Results: In 21.038 surgical pieces, the presence of Enterobius vermicularis was found in 322 (1.5 percent). Fifty nine percent were women and 71 percent were younger than 18 years. Acute inflammation was confirmed in 71 percent. A history of previous abdominal pain was present in 40 and 70 percent of patients with and without acute inflammation in the surgical piece. Conclusions: In this series, the frequency of Enterobius vermicularis presence in surgical pieces of appendectomy was 1.5 percent.


Introducción: La frecuencia de Enterobius vermicularis (EB) apendicular varía entre 0,2-41,8 por ciento, siendo generalmente su diagnóstico un hallazgo al estudio histopatológico. La obstrución luminal puede desencadenar un cólico apendicular o evolucionar a una apendicitis aguda, siendo por tanto una causa frecuente de apendicectomía. El objetivo del estudio es determinar la prevalencia de EB en piezas quirúrgicas de apendicectomía junto con describir características clínico-morfológicas. Material y Método: Cohorte retrospectiva de pacientes con oxiuriasis apendicular diagnosticados en el Hospital Hernán Henríquez Aravena entre 1993-2010. Se estudiaron variables clínico-morfológicas, utilizándose estadística descriptiva y analítica, aplicando Chi-cuadrado y test exacto de Fisher para variables categóricas y T-student para variables continuas con un IC de 95 por ciento. Resultados: En 21.038 apendicectomías se verificaron EB en 322 casos (1,53 por ciento). El 59 por ciento eran mujeres y 71 por ciento menor de 18 años. Inflamación aguda fue confirmada en 71 por ciento. En casos con inflamación aguda la temperatura rectal y recuento leucocitario promedio fue 380 C y 12.975 mm³ respectivamente, mientras que en casos sin inflamación 37,80 C y 10.984 mm³ (p = N.S). En el grupo apendicectomizado por sospecha de apendicitis el 40 por ciento tenía historia de dolor abdominal previo, mientras que en aquellos sin inflamación aguda asociada el 72 por ciento (p = 0,005). Conclusiones: La prevalencia de EB apendicular fue 1,53 por ciento, afectando fundamentalmente a niños-jóvenes del sexo femenino. La oxiuriasis apendicular representa una causa de dolor abdominal interpretado como apendicitis aguda, sin asociarse a inflamación en el examen anatomopatológico. La historia de dolor abdominal previo resultó una variable útil para discriminar cólico apendicular de apendicitis aguda.

ABSTRACT

Investigou-se a prevalência de infecções parasitárias do apêndice cecal e suas relações com a apendicite. Dos 1.600 apêndices estudados 24 (1,5 por cento) apresentaram infecção parasitária. Enterobius vermicularis foi encontrado em 23 casos (95,8 por cento) e Taenia sp em apenas um (4,2 por cento). Dezesseis pacientes (66,7 por cento) eram menores de 10 anos; 15 eram masculinos e 9 femininos. A análise histopatológica demonstrou inflamação aguda supurativa em 12 casos (50 por cento), eosinofilia em 13 (54,2 por cento) e hiperplasia linfóide em 10 (41,7 por cento). Complicações como peritonite ocorreram em 11 e gangrena em 3 casos. As infecções parasitárias do apêndice são causa pouco freqüente de apendicite aguda em crianças e adolescentes.


From 1,600 surgically removed appendices, 24 (1.5 percent) were found to have helminths. Enterobius vermicularis was observed in 23 of the 24 specimens (95.8 percent) and Taenia sp was detected in only 1 (4.2 percent) case. Sixteen patients (66.7 percent) were less than 10 year-old; 15 patients were male and 9 female. Pathologic analysis disclosed acute neutrophilic inflammation in 12 cases and lymphoid hyperplasia in 10 of the 24 appendices. Gangrenous appendicitis was diagnosed in 3 cases and peritonitis was found in 11 of the 24 infested appendices. Parasitic infection of the appendix is an uncommon cause of acute appendicitis in children and adolescents.

ABSTRACT

To evaluate the appendicitis due to Enterobius vermicularis. Appendices were removed and histopathological examination was carried out. The samples were obtained from patients admitted in Imam khomeini hospital at Ahvaz city, capital of Khouzestan Province, Southwestern part of Iran. 1253 appendices were examined in order to elucidate possible relationship between the incidence of Enterobius vermicularis and the origin of inflammation.Main outcome: Assesment of the appendicitis due to Enterobius vermicularis. Nine out of 1253 cases [0.7%] were infected with Enterobius vermicularis, including 5 female and 4 male at the age of 8-36 years. During the operation in two female cases, ovarian cysts were revealed at the same time. Existence of Enterobius vermicularis in appendicitis can cause the symptom and even inflammation of appendicitis

ABSTRACT

Abstract. There is little evidence regarding the relationship between parasites and acute appendicitis. In order to determine such a relationship, if any, 830 appendectomy specimens were studied. Age, sex, pathological findings and the presence and type of parasites and the type of parasite were analyzed. Parasites were present in 62 cases (7.46%). Ascaris lumbricoides and Trichuris trichiura were the most frequently encountered parasites. These were observed, alone or in combination, in 45 cases (72.5%). Appendix perforation, peritonitis, necrosis and flegmonous appearance, were more frequent in the cases of acute appendicitis without parasitic infestation (p < 0.05). There were no differences between the cases with or without parasitic infestation (p > 0.05) In cases of peritonitis. The low incidence of parasites among the appendectomy specimens and the failure to demonstrate its relationship with all events derived of appendicitis, do not support the hypothesis that parasites are a major cause of appendicitis in pediatric patients.


Resumen. Existe poca evidencia con respecto a la relación entre parásitos y apendicitis aguda. Con el objeto de clarificar dudas, se estudiaron 830 muestras de especimenes apendiculares. Se analizaron la edad, el sexo, los hallazgos histopatológicos, la presencia o no de parásitos y el tipo de parásito presente. Se observaron parásitos en 62 casos (7,46%). Ascaris lumbricoides y Trichuris trichiura fueron los parásitos mas frecuentemente visualizados, solos o en combinación en 45 casos (72,5%). La perforación apendicular, la peritonitis, la necrosis apendicular y las características flegmonosas del apéndice, fueron observados con mayor frecuencia en los casos sin infestación parasitaria (p < 0,05). En los casos de peritonitis, no se observó diferencia significativa entre los casos con o sin infestación parasitaria. La baja frecuencia de la presencia parasitaria en las biopsias estudiadas y la imposibilidad de demostrar una relación entre los parásitos y todas las manifestaciones histopatológicas de la apendicitis aguda, impiden afirmar que los parásitos constituyen una causa importante en la etiopatogénia de la apendicitis aguda en pacientes pediátricos.

ABSTRACT

Introducción. La patogénesis de apendicitis se desencadena por la obstrucción de su luz, generalmente causada por fecalitos. En ocasiones semillas, parásitos y huevos de parásitos son la causa de tal obstrucción. Material y métodos. Se realizó un estudio retrospectivo durante 1991-1995, con el fin de analizar la frecuencia y distribución de parásitos o huevos en las laminillas de muestras de apéndices de pacientes postoperados de apendicitis aguda. Las variables analizadas incluyeron: edad, sexo, cuadro clínico, diagnóstico preoperatorio y postoperatorio, complicaciones y morbilidad que pudiera estar asociada. Resultados. Se analizaron 479 pacientes que presentaron apendicitis aguda. Solamente 36 casos tenían huevos o parásitos intraluminales en las muestras histopatológicas. Los huevos de parásitos más frecuentes fueron Ascaris lumbricoides (17) y Enterobius vermicularis (8), y el parásito más común fue A. lumbricoides en 4 pacientes. El resto de los pacientes presento 2 o más huevos de diferentes parásitos en la luz apendicular: En estos 36 pacientes se asociaron 8 complicaciones: 4 abscesos de pared, 1 absceso pélvico y 3 subclusiones intestinales por A. lumbricoides en el postoperatorio inmediato. Conclusión. La apendicitis aguda asociada a parasitos intraluminales, como causa o en asociación, se presenta en nuestro medio más frecuentemente que lo reportado en la literatura. La distribución más frecuente por edad de esta asociación resultó ser la etapa escolar: Debido a la identificación de A. lumbricoides en el postoperatorio para disminuir complicaciones asociadas

ABSTRACT

In cases of schistosomiasis, the appendix is commonly infested. It is not known if this is a predisposing factor for appendicitis, or a mere coincidental histological finding. Patients and A total of 56 patients [51 males and 5 females] underwent appendectomy for schistosomal appendicitis over a 10-year period at Dammam Central Hospital. The histological slides of 41 of the patients [73.2%] were retrospectively studied. The highest incidence of schistosomal appendicitis was recorded in the 21-40-year age group. Ova were seen in the submucosal layers of all the excised appendices. The most common tissue responses were submucosal fibrosis [92.7%] and eosinophilia [87.8%], followed by the presence of suppurative inflammation [80.5%]. Granulomatous reaction was evident in only 13 cases [31.7%]. A striking feature was atrophy of submucosal lymphoid follicles in 70.7% of the cases. Hyperplasia of lymphoid follicles and serosal granulomas were rare [2.4%]. Similar tissue responses were histologically seen in four normal appendices examined. Appendiceal infestation may predispose to appendicitis in the majority of affected cases, but in others, it may well be a mere coincidental histological finding. However, preoperative knowledge bears no clinical significance and does not alter management
