Ruptura de quiste hidatídico hepático hacia cavidad torácica por trauma tóraco-abdominal. Dificultades en el diagnóstico / Rupture of a hepatic hydatid cyst towards the chest cavity after an abdominal-chest trauma. Difficulties in the diagnosis

RESUMEN La equinococosis es una infección zoonótica causada por el cestodo del género Echinococcus, endémica en muchas regiones del Perú. Los quistes hidatídicos habitualmente se ubican en el hígado y pulmón, siendo infrecuente tanto su localización en otros órganos como la hidatidosis múltiple. La mayoría de ellos son asintomáticos y de hallazgo incidental, aunque también pueden ocurrir complicaciones, como su ruptura espontánea o traumática que tiene una mínima incidencia (3-17%), siendo insólito que se dé hacia el tórax. Se presenta el caso de un paciente con ruptura de quistes hidatídicos hepáticos hacia la cavidad pleural, por traumatismo tóraco-abdominal, que al constituir una presentación excepcional de la patología originó dificultades en su reconocimiento inicial teniéndose como diagnóstico diferencial un hemotórax masivo. Este finalmente fue superado por la revisión de imágenes tomográficas con las que se concluyó una hidatidosis hepática complicada.

SUMMARY Cystic hydatidosis is a zoonotic infection caused by the cestode Echinococcus, which is endemic in many regions of Peru. Hydatid cysts are usually located in the liver and lungs, locations elsewhere are rare as well as multiple hydatidosis. Most of the hydatid cysts are asymptomatic and are found incidentally. Rare complications may arise such as spontaneous or traumatic rupture (3-17%), it is very infrequent that the hydatid cyst rupture towards the chest wall. We present a case of a patient who suffered the rupture of hepatic cysts into the pleural cavity after an abdominal-chest trauma, the rarity of this event made the identification of the problem more difficult to be confused with massive hemothorax. Careful review of the CT-Scan images allowed to reach the correct diagnsosis.

Application value of Revolution CT combining three-dimensional visualization technique in precision resection of hepatic alveolar echinococcosis / 中国血吸虫病防治杂志

Objective To explore the application value of Revolution CT combining three -dimensional visualization technique in the precision resection of hepatic alveolar echinococcosis. Methods Totally 12 patients with surgical treatment and pathologically confirmed hepatic alveolar echinococcosis in Qinghai Provincial People’s Hospital were retrospectively analyzed. All the patients underwent the Revolution CT plain and enhancement scan before surgery, and the 0.625 millimeter scan data were obtained. The DICOM format data were imported into MI-3DVS for three-dimensional reconstruction, simulated cutting, volume measurement, and surgical planning. Results The data of 12 patients were reconstructed successfully, and the sizes and locations of the lesions as well as the hepatic vascular systems were clearly displayed. The liver volume, hydatid volume, simulated resection volume, and residual liver ratio were measured accurately. The average whole liver volume and the lesion volume of the 11 surgical treated patients were (2 429.8 ± 335.9) mL and (919.6 ± 262.8) mL respectively. The average actually removed volume was highly associated with the average simulated resection volume (r = 0.979, P < 0.01). Conclusion Revolution CT combining three-dimensional visualization technique can achieve accurate diagnosis as well as optimal surgical planning before operation, which is of great value for the precision resection of difficult hepatic alveolar echinococcosis.

Surgical treatment strategy for complex hepatic echinococcosis: a review / 中国血吸虫病防治杂志

The hepatic echinococcosis is an anthropozoonosis and caused by the larva of Echinococcus. The main pathogenic type of Echinococcus in China is E. granulosus and E. multilocularis, which cause cystic echinococcosis and alveolar echinococcosis respectively. At present, the treatment of hepatic echinococcosis has made great progress, but there are still some difficulties in the treatment of complex echinococcosis, especially of the cases existing one or more complications, and the focus of infection encroaching the hepatic portal, important vessels and bile vessel. This paper based on the literature reports and clinical experiences in recent years, puts forward the surgical treatment strategy for complex hepatic echinococcosis.

Expression of follicular helper T cells in peripheral blood of patients with hepatic echinococcosis / 中国血吸虫病防治杂志

Objective To detect the expression of follicuLar helper T cells (Tfh) and interleukin-21 (IL-21) in the peripheral blood of patients with hepatic echinococcosis and healthy controls, so as to explore the associations of Tfh and IL-21 expression with the progression of hepatic echinococcosis. Methods Fifty cases of hepatic echinococcosis and healthy controls were collected from Qinghai Provincial People's Hospital, respectively. Flow cytometry was used to detect the expression of Tfh cells in the peripheral blood of hepatic echinococcosis patients and healthy controls, and enzyme-linked immunosorbent assay (ELISA) was used to detect serum IL-21 expression in hepatic echinococcosis patients and healthy controls. The correlation between Tfh cell expression and serum IL-21 level was examined in the patients with hepatic echinococcosis. Results Flow cytometry detected a higher percentage of CD4+CXCR5+ T cells (18.49% ± 5.67% vs. 16.18% ± 4.04%, P < 0.05), CD4+CXCR5+PD-1+ T cells (4.94% ± 1.91% vs. 2.29% ± 0.79%, P < 0.05) and CD4+CXCR5+ICOS+PD-1+ T cells (30.93% ± 24.10% vs. 21.07% ± 14.25%, P < 0.05) in hepatic echinococcosis patients than in healthy controls, and no significant difference was seen in the percentage of CD4+CRCR5+ICOS+ T cells between the patients and controls (0.29% ± 0.32% vs. 0.25% ± 0.31%, P > 0.05) . The serum IL-21 level was significantly higher in the patients with hepatic echinococcosis than in healthy controls ([ 293.35 ± 2 03.65) pg/mL vs. (192.72 ± 70.09) pg/mL, P < 0.05]; however, there was no correlation between the Tfh cell expression and serum IL-21 level in patients with hepatic echinococcosis (P > 0.05). Conclusion The expression of peripheral blood Tfh cells and serum IL-21 is elevated in patients with hepatic echinococcosis, and Tfh cells and IL-21 may contribute to the progression of hepatic echinococcosis.

Surgical alternatives used in the treatment of liver hydatid cyst: a systematized approach based on evidence (an overview) / Alternativas quirúrgicas utilizadas en el tratamiento del quiste hidatídico hepático: revisión global de la evidencia

Echinococcosis is an endemic zoonosis in the south of Chile; we therefore have occasion to treat a large number of patients, particularly in the liver. Hepatic echinococcosis (HE) has its own morbidity and mortality due to evolutionary complications, to which the risk of complications related to the surgical procedures is added, the morbidity which has been reported up to 80 %. This is associated with a history of previous surgeries for HE, evolutionary complications of the cyst, the need for additional procedures such as the treatment of the disease in other simultaneous locations, etc. Moreover, reported mortality is up to 10 %, a situation that remains unchanged despite technological and therapeutic advances. The surgical treatment of HE can be divided into four phases: isolation of the surgical area, evacuation of the cyst, treatment of the complications of the cyst and treatment of the residual cavity. HE surgical procedures can be classified as conservative (marsupialization, cystostomy, Posadas technique and cystojejunostomy) and radical (pericystectomy and hepatic resections). Finally, the role of laparoscopic surgery, which is still under evaluation, is also worthy of note. The aim of this article is to present a general evidence-based overview of some surgical aspects of interest in the treatment of HE. In this article issues of the different surgical options utilized for HE treatment and their results are discussed, based on published evidence.

La equinococosis es una zoonosis endémica en el sur de Chile; por lo tanto, tenemos la oportunidad de tratar un gran número de pacientes, particularmente en el hígado. La equinococosis hepática (EH) tiene su propia morbilidad y mortalidad debido a complicaciones evolutivas, a lo que se añade el riesgo de complicaciones relacionadas con los procedimientos quirúrgicos. Se ha informado una morbilidad hasta del 80 %. Esto se asocia con antecedentes de cirugías previas para EH, complicaciones evolutivas del quiste, la necesidad de procedimientos adicionales, tales como el tratamiento de la enfermedad en otros lugares en forma simultánea, etc. Por otra parte, la mortalidad reportada alcanza el 10 %, una situación que se mantiene sin cambios a pesar de los avances tecnológicos y terapéuticos. El tratamiento quirúrgico de la EH se puede dividir en cuatro fases: aislamiento de la zona quirúrgica, evacuación del quiste, tratamiento de las complicaciones del quiste y tratamiento de la cavidad residual. Los procedimientos quirúrgicos de la EH se pueden clasificar en conservador (marsupialización, cistostomía, técnica y cistoyeyunostomía de Posadas) y radical (periquistectomía y resecciones hepáticas). Por último, el papel de la cirugía laparoscópica, que todavía está en proceso de evaluación, también es digno de mención. El objetivo de este artículo es presentar una visión general basada en la evidencia de algunos aspectos quirúrgicos de interés en el tratamiento de la EH. Se discuten los temas desde las diferentes opciones quirúrgicas utilizadas para el tratamiento de la EH y sus resultados, sobre la base de la evidencia publicada.

Chronic Hydatid Cyst in Malaysia: A Rare Occurence

Hydatid cysts are not endemic in Malaysia and are rarely seen. We hereby report a case of hydatid cyst of the liver in a 55-year-old Chinese-Australian lady who presented with a calcified liver cyst and negative hydatid serology. A liver segmentectomy was performed and revealed a well-circumscribed, calcified liver cyst containing only creamy whitish material without the typical daughter cyst. A histological examination revealed different layers of the cyst wall and the presence of loose, calcified scolices without a daughter cyst. The case highlights the importance of considering hydatid cyst in the differential diagnosis of liver cyst even in non-endemic areas, as the ease of travelling and migration allows the condition to be seen outside the endemic region.

Long-term outcomes of intraoperative and perioperative albendazole treatment in hepatic hydatidosis: single center experience

PURPOSE: The aim of this study was to evaluate long-term outcome of the intraoperative and perioperative albendazole (ALB) treatment on the recurrence and/or secondary hydatidosis. METHODS: One hundred and one patients with hepatic hydatidosis were treated intraoperatively and perioperatively with ALB, in addition to surgery. Perioperative ALB treatment was given in a dose of 12-15 mg/kg/day. The ALB treatment was started 13.27 +/- 14.34 days before the surgery, and it was continued for 4.39 +/- 3.11 months postoperatively. A total of 1.7 microg/mL of ALB solution was used as a protoscolidal agent. The follow-up period was 134.55 +/- 51.56 months. RESULTS: Four patients died, with only one death was secondary to hydatid disease (cerebral eccinococcus). There was only one recurrence (1%) of hepatic hydatidosis. Early and late morbidity rates were 8.91% and 7.92%, respectively. CONCLUSION: Our results suggest that intraoperative and perioperative ALB is effective for the prevention of hepatic hydatidosis recurrence and/or secondary hydatidosis.

Hidatidosis poliquística autóctona en dos pacientes Yanomami en el Alto Orinoco, Amazonas, Venezuela / Polycystic hydatid disease in two patients indigenous Yanomami in the Upper Orinoco, Amazonas, Venezuela

La infección por Echinococcus sp. es hipoendémica en Venezuela. Sólo cuatro casos de hidatidosis autóctona por E. vogeli han sido reportados, tres de ellos en la región de la Guayana venezolana. En Febrero del año 2009 se realizó el diagnóstico clínico-sero-epidemiológico de hidatidosis poliquística en una paciente femenina de la etnia Yanomami, procedente de Parima B, Alto Orinoco, en la Amazonía venezolana. Se resolvió con tratamiento médico y quirúrgico por laparoscopia y se evidenció en el quiste la presencia de ganchos rostelares compatibles con E. vogeli. En Abril del 2009 en una segunda paciente Yanomami de igual procedencia, se le diagnosticó hidatidosis por E. vogeli siendo operada exitosamente por cirugía laparoscópica asistida por robot. Dos casos humanos en una misma población y la presencia de factores de riesgo como la tenencia de perros domésticos y la comunicación por informantes indígenas del hallazgo de quistes en hígados de animales de cacería (Cuniculus paca o lapa y Dasyprocta sp. o picure), hacen pensar en transmisión activa en la cuenca del Alto Orinoco y en zonas selváticas de la Guayana venezolana. El presente, es el primer registro de casos de hidatidosis poliquística en indígenas de la etnia Yanomami.

Infection by Echinococcus sp. is hypoendemic in Venezuela. Only four cases of autochthonous E. vogeli hydatidosis have been reported, including three in the Venezuelan region of Guayana. In February 2009, based on epidemiological data, signs and symptoms and serological tests, a female patient of the Yanomami ethnic group, was diagnosed with a polycystic hydatid disease in Parima B, Alto Orinoco, in the Venezuelan Amazon. Rostellar hooks compatible with E. vogeli were found in the cyst. It was resolved with medical and surgical treatment by laparoscopy. A second Yanomami patient from the same location was diagnosed with E. vogeli hydatidosis in April 2009, being successfully operated with robot-assisted laparoscopy. Two human cases in the same population and the presence of risk factors such as domestic dog ownership and findings of cysts in livers of hunted animals (such as Cuniculus and Dasyprocta sp.) reported by indigenous informants, suggest active transmission in the Upper Orinoco basin and forested areas of the Venezuelan Guayana. These are the first reported cases of polycystic hydatid disease of the Yanomami ethnic group.
