Ascariasis is an intestinal disease caused by Ascaris lumbricoides. Most patients with ascariasis are asymptomatic; however, the presence of many larvae in the bowel can cause gastrointestinal complications, such as intestinal obstruction, obstructive jaundice, cholangitis, cholecystitis, and pancreatitis. Herein, we report a case of ascariasis presenting as hematoma and active bleeding in the sigmoid mesocolon of a 74-year-old man on computed tomography (CT). Sigmoid colon perforation was also detected on follow-up CT. Laparoscopic low anterior resection was performed; there was a large hematoma in the sigmoid mesocolon. Roundworms were microscopically identified in the mesenteric adipose tissue. The clinical and CT findings of this unusual presentation of ascariasis revealed serial complications during parasite migration from the intestinal lumen to the peritoneal cavity.

“…"una causa no sospechada" R.F.S Revista Facultad de Salud Julio-Diciembre de 2015;7(2):57-60 hemorragia digestiva de origen oscuro oculta o manifiesta, siendo la presentación con anemia ferropenica y sangre oculta en heces la más frecuente, e inusualmente con sangrado evidente, donde se ha requerido la realización de varios procedimientos endoscópicos para llegar al diagnóstico [16][17][18][19][20][21][22] . Lo que plantea el interrogante si a estos pacientes que se presentan por primera vez con sangrado gastrointestinal y evaluación endoscópica estándar negativa deben ser desparasitados profilácticamente en zonas donde la prevalencia de parasitismo intestinal es alta, como nuestro país, antes de presentar un nuevo episodio de sangrado y requerir la realización de más procedimientos endoscópicos para determinar la etiología, como ocurrió en nuestra paciente.…”

La hemorragia digestiva de origen oscuro se presenta en el 5 -10% del sangrado intestinal, con persistencia o recurrencia en el 50%, de los casos. Es ocasionado por varías etiologías, generando un desafío diagnóstico que requiere la realización de varios procedimientos endoscópicos. Entre las causas inusuales se encuentran las parasitosis intestinales por nematodos, siendo prevalentes en zonas tropicales y países en vía de desarrollo. Presentamos el caso de una paciente con hemorragia digestiva de origen oscuro manifiesto recurrente desencadenado por Ascaris lumbricoides, quien requirió varias hospitalizaciones, soporte transfusional y realización de un set de procedimientos endoscópicos previo al diagnóstico etiológico y posterior tratamiento planteando la necesidad de conocer la real costo efectividad de la desparasitación profiláctica en todo paciente con hemorragia intestinal y primera evaluación endoscópica estándar negativa, teniendo en cuenta la alta prevalencia de nematodos en nuestro país.

Background and study aim: Helminthic and protozoal infestation of the alimentary tract is endemic in tropical and subtropical areas and also occur in temperate zones. The aim of this study was to evaluate the frequency and characterization of parasites detected during upper digestive endoscopic procedures. Patients and methods: Retrospective analysis of the records of patients exposed to upper endoscopic procedures in the endoscopy units, Tropical Medicine Department, Zagazig University Hospitals, Egypt in a 5 year period extending from January 2007 to January 2012. A total of 4925 cases were included; 4708 cases for gastrodudenoscopy (EGDS) and 217 cases for endoscopic-retrogradecholangio-pancreatography (ERCP). All cases were reviewed as regard age, sex, residence, indications for endoscopy and endoscopic features. Cases with parasitic infestations were characterized regarding the mentioned variables. Results: A total of 8 cases with parasitic infestations were described. Six cases detected by EGDS and 2 cases by ERCP. Five cases were Ancylostoma duodenale , one case Ascaris lumbricoides, one case Strongyloides stercoralis and one case Fasciola hepatica. Most cases were presented with anemia and persistent epigastric pain. Seven cases were associated with duodenitis on endoscopic examination. Conclusion: Parasites are not common findings during upper digestive endoscopic procedures, and should be suspected in patients with anemia and persistent epigastric pain.
