Manejo complicaciones biliares de la cirugía del quiste hidatídico hepático / Management of biliary complications of liver hydatid cyst surgery

Resumen La complicación más frecuente del quiste hidatídico hepático es la fístula biliar externa. El diagnóstico pre e intraoperatorio es esencial en el tratamiento. En dicha evaluación se describen factores predictivos que hacen sospechar las comunicaciones cistobiliares. En presencia de estas, es posible realizar estudios adicionales para su diagnóstico. La filtración y la fístula biliar son las complicaciones postoperatorias más frecuentes y las principales causas de morbimortalidad. Sus tasas pueden disminuirse siguiendo con acuciosidad los factores predictivos y el adecuado manejo de la fístula biliar postoperatoria.

The most frequent complication of hepatic hydatid cyst is the external biliary fistula. Pre and intraoperative diagnosis is essential in treatment. This evaluation describes predictive factors that make cystobiliary communications suspicious. In the presence of these it is possible to carry out additional studies for its diagnosis. Filtration and biliary fistula are the most frequent postoperative complications and the main causes of morbidity and mortality. Their rates can be decreased by acutely following the predictive factors and proper management of postoperative biliary fistula.

A rare location of primary extrahepatic hydatid cyst in the soft tissue

Hydatid cyst or cystic echinococcosis in human is rare disease caused by tapeworm Echinococcus granulosa. Hydatid cyst of soft tissue is a rare condition and we had a case of large hydatid cyst in lumbar region. This is a case of 48 years old female presented to us during October 2018 with a large diffuse swelling over the left lumbar region which was gradually grown over the last 2 years without pain. The diagnosis of hydatid cyst was not sure even in CT scan but it was in our differential diagnosis. It is confirmed during surgery after seen the multiple cyst removed from the large cystic lesion. No recurrence even after 15 months of follow up. Presence of hydatid cyst in soft tissue is usually rare and its diagnosis is not expected clinically when it presents as a soft tissue swelling. We need to confirm it during surgery or by presence of typical germinal membrane under microscope.

A clinical study for preoperative prediction of cyst-biliary communications in hepatic hydatid cyst disease

Background: Cyst-biliary communication with hepatic hydatid cyst disease is responsible for postoperative bile leakage after surgical management. This study aims to detect various predictors of cyst-biliary communication and their predictive accuracy.Methods: This study was done in the patients of hydatid cysts who underwent surgical management for hydatid disease of the liver. Various factors were studied and their accuracy for preoperative prediction of cyst-biliary communication analyzed.Results: There were 38 (22 males, 16 females) patients with hepatic hydatid cysts with a mean age of 38.7±15.4 years. Cyst-biliary communications were detected in 12 patients (31.6%). Independent strong predictors were tenderness in right hypochondrium (p=0.035), total leucocyte count (TLC)>12,000/mm3 (p=0.0017),  eosinophil count >5 × 108/l (p=0.0086), red blood cell distribution width (RDW) >15% (p=0.014), segment IV,V,VII involvement and cyst size >10 cms (p=0.01) on multivariate analysis.Conclusions: Cyst-biliary communication is more common in patients presenting with tenderness in right hypochondrium, large cyst size, location in the central segments of liver close to biliary confluence, and with high values of TLC, Eosinophil count and RDW. The predictors demonstrated in this study should allow the likelihood of cyst-biliary communication to be determined preoperatively and, thus, indicate the need for additional procedures during operations to prevent the complications of biliary leakage.

Early and late outcomes of surgery of non-complicated liver hydatid / Resultados precoces y tardíos de la cirugía de la hidatidosis hepática no complicada

Hepatic echinococcosis (HE) is a prevalent health problem, and there is limited published information regarding HE surgery. On the other hand, postoperative morbidity (POM) has not varied significantly. The aim of this study was to describe early and late outcomes in terms of POM of a series of patients with non-complicated liver hydatid cysts (NLHC) treated surgically. Prospective cohort. We included patients undergoing surgery for NLHC in the Hospital Regional and Clínica in Temuco, between 2000 and 2015. The main outcome variable was the development of early and late POM. Other variables of interest were hospital stay, mortality and recurrence. Surgical techniques used were total or subtotal pericystectomy and liver resection. Percentages, measures of central tendency and dispersion, and incidence were calculated. We studied 136 patients with a median age of 41 years and 60.3 % female The median ultrasound diameter of the cysts was 15.0 cm. The median surgical time was 95 minutes. The incidence of POM was 9.6 %, 92.3 % of whose cases were Grade I or II Dindo & Clavien. The aetiology was 5.9 % and 3.7 % medical complications of surgical complications. There was no mortality and with a median follow up of 115 months, recurrence was observed in one patient, representing an incidence of 0.7 %. POM was determined in a cohort of patients with NLHC throughout an extended follow-up period, and the incidence and gravity of POM is smaller and of lower gravity than those previously published.

Siendo una equinococosis hepática (EH) un problema de salud prevalente, la información publicada respecto a la cirugía de EH no es abundante. Por otro lado, la morbilidad postoperatoria (MPO) no ha variado de forma muy significativa.

Estudio de cohorte prospectiva. Se incluyeron pacientes sometidos a cirugía para QHHN en el Hospital Regional y Clínica en Temuco, entre 2000 y 2015. La variable resultado principal fue desarrollo de MPO temprana y tardía. Otras variables de interés fueron estancia hospitalaria, mortalidad y recurrencia. Las técnicas quirúrgicas utilizadas fueron periquistectomía total o subtotal y resección hepática. Se calcularon porcentajes, medidas de tendencia central y dispersión, e incidencia. Se estudiaron 136 pacientes con una mediana de edad de 41 años; 60,3 % de los cuales son mujeres. La mediana del diámetro de los quistes y del tiempo quirúrgico fue de 15,0 cm y 95 min. Respectivamente. La incidencia de MPO fue 9,6 %, de los cuales 92,3 % fueron Grado I o II de Dindo y Clavien. La etiología fue: 5,9 % de complicaciones médicas y 3,7 % de complicaciones quirúrgicas. No hubo mortalidad; y con una mediana de seguimiento de 115 meses, se determinó una incidencia de recidiva de 0,7 % (1 paciente, en el período estudiado). Se describe la MPO de una cohorte de pacientes con QHHN. La morbilidad observada es inferior a la publicada y de bajo nivel de gravedad.

Cholangiohydatidosis: an Infrequent Cause of Obstructive Jaundice and Acute Cholangitis

ABSTRACT Background. One of the evolutionary complications of hepatic echinococcosis (HE) is cholangiohydatidosis, a rare cause of obstructive jaundice and cholangitis. The aim of this study was to describe the results of surgical treatment on a group of patients with cholangiohydatidosis and secondary cholangitis in terms of post-operative morbidity (POM). Material and method. Case series of patients operated on for cholangiohydatidosis and cholangitis in the Department at Surgery of the Universidad de La Frontera and the Clínica Mayor in Temuco, Chile between 2004 and 2014. The minimum follow-up time was six months. The principal outcome variable was the development of POM. Other variables of interest were age, sex, cyst diameter, hematocrit, leukocytes, total bilirubin, alkaline phosphatase and transaminases, type of surgery, existence of concomitant evolutionary complications in the cyst, length of hospital stay, need for surgical re-intervention and mortality. Descriptive statistics were calculated. Results. A total of 20 patients were studied characterized by a median age of 53 years, 50.0% female and 20.0% having two or more cysts with a mean diameter of 13.3 ± 6.3 cm. A median hospital stay of six days and follow-up of 34 months was recorded. POM was 30.0%, re-intervention rate was 10.0% and mortality rate was 5.0%. Conclusion. Cholangiohydatidosis is a rare cause of obstructive jaundice and cholangitis associated with significant rates of POM and mortality.(AU)

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.

Morbilidad postoperatoria en pacientes con hidatidosis hepática complicada / Post surgery morbidity in patients with complicated hepatic hydatidosis

Introduction: Hepatic echinococcosis (HE) surgery is common in southern's Chile hospitals; however, related publications are scarce and with conflicting results, especially with regard to postoperative morbidity (POM), due to the diversity in it severity. The aim of this study is to determine POM in patients undergoing surgery for complicated HE (CHE). Material and Methods: Case series part of a prospective cohort. Patients undergoing surgery for CHH in hospitals Hernán Henríquez Aravena hospital and Clínica Mayor of Temuco, between 2000 and 2012 were included. The main outcome variable was development of POM using the Clavien scale. Other variables of interest were hospital stay, mortality and recurrence. Descriptive statistics were applied and incidence of POM was determined. Results: 73 patients with a median age of 41 years and 58.9% female were studied. The median ultrasound diameter cysts were 15.0 cm. The average surgical time was 125.4 ± 26.3 min. The surgical procedure used most often was the pericystectomy (84.9%); and 84.9% of cases was performed concomitantly some other surgical procedure. The incidence of POM was 19.2%, 78.6% of whose cases were Grade I or II Clavien. The aetiology was 10.9% of medical complications and 8.2% of surgical complications. 1.4% of mortality was recorded; and with a median follow up of 97 months, no recurrence was verified. Conclusions: POM in a cohort of patients with CHE is lower than the published and low severity. Subgroups with higher POM were: patients with coexistence of more than one complication, those with colangiohydatidosis and patients with liver abscess of hydatid origin.

Introducción: La cirugía de la hidatidosis hepática (HH) es habitual en hospitales del sur de Chile; sin embargo, las publicaciones relacionadas son escasas y sus resultados disímiles, en especial respecto de la morbilidad postoperatoria (MPO), debido a la diversidad en la gravedad. El objetivo de este estudio es determinar la incidencia de MPO en pacientes intervenidos quirúrgicamente por HH complicada. Material y Método: Serie de casos, parte de una cohorte prospectiva. Se incluyeron pacientes intervenidos quirúrgicamente por HH complicada, en el hospital Hernán Henríquez Aravena y en la Clínica Mayor de Temuco, entre 2000 y 2012. La variable resultado principal fue desarrollo de MPO aplicando la escala de Clavien. Otras variables de interés fueron estancia hospitalaria, mortalidad y recurrencia. Se aplicó estadística descriptiva y, se determinó incidencia de MPO. Resultados: 73 pacientes, con mediana de edad de 41 años (16 a 84 años); 58,9% de género femenino. La mediana del diámetro ultrasonográfico de los quistes fue de 15,0 cm. El tiempo quirúrgico promedio fue de 125,4 ± 26,3 min. El procedimiento quirúrgico utilizado con mayor frecuencia fue periquistectomía (84,9%); y en 84,9% de los casos se realizó de forma concomitante algún otro procedimiento quirúrgico. La incidencia de MPO fue 19,2% (10,9% de tratamiento médico y 8,2% de tratamiento quirúrgico); 78,6% de cuyos casos eran Grado I o II de Clavien. Se registró 1,4% de mortalidad; y con una mediana de seguimiento de 97 meses, no se verificó recurrencia. Conclusiones: La incidencia de MPO en pacientes con HH complicada es inferior a la publicada y de bajo nivel de gravedad. Los subgrupos de complicaciones evolutivas con mayor MPO fueron la co-existencia de más de una complicación, la colangiohidatidosis y el absceso hepático de origen hidatídico.

Laparoscopic partial cystectomy for the treatment of hepatic hydatid cysts.

Background: The laparoscopic approach for the treatment of hepatic hydatid cysts is increasingly gaining importance. The aim of this study was to report a series of 27 patients with hepatic hydatid cyst managed with laparoscopic partial cystectomy. Methods: A retrospective review of patients treated at a university clinic for hepatic hydatid cysts from March 2010 to May 2014 was performed. Operative time, blood loss, length of hospital stay, post-operative complications, and early follow-up outcomes were evaluated. Results: Laparoscopic surgical intervention was performed on 27 patients (17 females and 10 males)who were diagnosed with hydatid cysts by ultrasonography and computed tomography (CT). Except 3 of the cysts, were located in the right lobe of the liver. No mortality was noted during the study. Two surgical site infections were observed and no abscesses developed in the cystic cavity. Recurrence was not noted during the mean follow-up Period of 22 months. Conclusion: Laparoscopic partial cystectomy is a safe and effective method for the treatment of hepatic hydatid cyst.

Hepatic hydatid cyst: a non-surgical approach / Cisto hidático hepático: abordagem não cirúrgica

Echinococcosis/hydatidosis is common in societies where agriculture and livestock are frequent, and represents a public health problem. The therapeutic management depends on the cyst's characteristics, the patient, and surgical contraindications. Endoscopic retrograde cholangiopancreatography is a valuable tool in the diagnosis and treatment of complicated hepatic hydatid disease. Ultrasonography is a useful diagnostic, therapeutic and follow-up tool. The authors report a case of a 56 years old patient who was diagnosed with a hepatic hydatid cyst in the IVa/VIII segments, describe the therapeutic options and 50 months of disease-free follow-up.

A equinococose/hidatidose é comum em sociedades onde predominam a agricultura e a criação de gado, sendo um problema de saúde pública. As várias opções terapêuticas dependem das caraterísticas do quisto, do doente e da eventual presença de contraindicações cirúrgicas. A colangiopancreatografia retrógrada endoscópica constitui uma válida ferramenta no diagnóstico e tratamento da doença hidática hepática complicada. A ecografia é um instrumento útil no diagnóstico, na terapêutica e seguimento. Os autores apresentam um caso de uma doente de 56 anos a quem foi diagnosticado um quisto hidático hepático nos segmentos IVa/VIII, descrevem as opções terapêuticas e o seguimento de 50 meses livres de doença.

Quince años de experiencia clínica con hidatidosis / Clinical presentation of hydatid disease during 15 years: a case series from Santiago, Chile

Introduction: Hydatidosis is a neglected parasitic disease that is endemic in Chile. We present the clinical experience of a single center in Santiago from 1996 to 2010. Methods: Cases were identified using hospital's database. Clinical and pathological features, treatment and outcomes were retrospectively analyzed. Results: In total, 23 patients were identified requiring 30 surgical interventions. Median age was 40 years old (range 5 to 73), and 76.5% visited or resided in regions of known endemicity in Chile. Abdominal cysts were predominant (78.3%), and most patients were symptomatic (73.9%). Elimination of cyst material by cough was reported in 42.9% of patients with symptomatic thoracic cysts. Eosinophilia was present in 41.2% of patients, and 57.1% had positive serology for hydatidosis. Aill patients underwent surgical treatment, in 60.9% in combination with albendazole treatment. While the majority of liver cysts (88.9%) were treated by complete cyst resection, lung cysts (83.3%) were predominantly treated by cyst resection plus capitonnage. Pathological examination revealed fertile cysts in 24%. Postsurgical morbidity was frequent (37.9%), and 13.3% of the series required readmission for this cause. Near 25% of patients remained in hospital > 14 days, a feature associated with fever during admission (p < 0.05). No recurrence was reported in the fraction of patients that were followed-up for 2 years or more. Conclusions: Our analysis of 23 cases demonstrates that patients were mainly adults suffering from abdominal cysts. Most patients were successfully treated by surgery with or without antiparasitic drugs but complications leading to prolonged hospital stays and readmissions were not infrequent.

Introducción: La hidatidosis es una enfermedad endémica en Chile. Se presenta la experiencia clínica de un hospital en Santiago, desde 1996 al 2010. Métodos: Los casos fueron identificados usando las bases de datos institucionales y se analizaron las características clínicas y patológicas, el tratamiento y la evolución en forma retrospectiva. Resultados: Se identificaron 23 pacientes intervenidos en 30 oportunidades. La mediana de edad fue de 40 años (rango 5 a 73) y 76,5% visitó o residía en zonas endémicas en Chile. Los quistes abdominales fueron predominantes (78,3%) y la mayor parte de los pacientes eran sintomáticos (73,9%). Un 42,9% de aquellos con quistes sintomáticos torácicos reportó eliminación de vesículas con la tos. Un 41,2% presentó eosinofilia y 57,1% tuvo serología positiva para hidatidosis. Todos los pacientes fueron tratados quirúrgicamente, en 60,9% en combinación con albendazol. La mayoría de los quistes hepáticos fueron tratados con cirugía radical (88,9%) y los pulmonares predominantemente con quistostomía y capitonaje (83,3%). Un 24% de los quistes eran fértiles. La morbilidad post-quirúrgica fue frecuente (37,9%) y 13,3% de la serie requirió reingresos por esta causa. Cerca de 25% de los pacientes estuvo hospitalizado por más de 14 días, un fenómeno asociado con la presencia de fiebre por complicación séptica al ingreso (p < 0,05). No se registraron recurrencias en la fracción de pacientes seguidos por más de dos años. Conclusiones: La hidatidosis afecta principalmente a adultos en su cavidad abdominal. Aunque los pacientes fueron tratados exitosamente con cirugía, las complicaciones, estadías prolongadas y reingresos por esta causa no fueron infrecuentes.

Aspectos clínico-quirúrgicos de la hidatidosis hepática, una zoonosis de creciente preocupación / Clinical and surgical aspects of hydatidosis

Hydatidosis is common in Southern Chile and it is usually located in the liver. The complications of surgical procedures for liver hydatidosis, which fluctuate from 11 to 86 percent, are superposed to the own complications of the disease. The frequency of surgical complications is associated with evolutionary complications of the cysts, the need to perform additional procedures to treat the disease in other simultaneous locations and previous surgical interventions for the disease. Operative mortality is lower than 5 percent. The surgical treatment of hydatidosis is divided in four phases: isolation of the surgical zone, cyst evacuation, treatment of cyst complications and treatment of residual cavity. The conservative surgical procedures are marsupialization, cystostomy, Posadas intervention and cystojejunostomy. Surgical procedures involving resection are pericys-tectomy, subtotal cystectomy and liver resections. The role of laparoscopic surgery is still under evaluation.

La hidatidosis es una zoonosis endémica en el sur de Chile, por lo que tenemos la oportunidad de tratar un número importante de pacientes, especialmente hepática, localización más común de esta enfermedad. La hidatidosis hepática (HH) tiene morbilidad y mortalidad propia debido a sus complicaciones evolutivas, a lo que se agrega el riesgo de complicaciones asociados a los procedimientos quirúrgicos, cuya morbilidad se ha reportado entre 11 por ciento y 86 por ciento; la que se ha relacionado con intervenciones previas por HH, complicaciones evolutivas de los quistes, la necesidad de realizar procedimientos adicionales como el tratamiento de la enfermedad en otras localizaciones simultáneas. La mortalidad reportada es inferior al 5 por ciento. Sin embargo, tanto morbilidad como mortalidad persisten altas a pesar de los avances tecnológicos terapéuticos. El tratamiento quirúrgico de la HH 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. Por otro lado, la cirugía de la HH se puede clasificar en procedimientos conservadores (marsupialización, quistostomía, operación de Posadas y quistoyeyunostomía) y resectivos (periquistectomía, quistectomía subtotal y resecciones hepáticas). Por último, cabe señalar el rol de la cirugía laparoscópica, que aún se encuentran en evaluación.

Morbilidad postoperatoria en pacientes con hidatidosis hepática no complicada: utilización de una propuesta de clasificación de complicaciones / Complications after surgery for hepatic hydatidosis: experience in 116 patients

Background: Surgery for hepatic hydatidosis is common in Southern Chile and it is important to know the rates of complications of the procedure. Aim: To report the rates of postoperative complications in patients operated for uncomplicated hepatic hydatidosis. Material and Methods: Prospective study of patients operated for uncomplicated hepatic hydatidosis between 1997 and 2008. The surgical techniques employed were total or partial peri cystectomies, or hepatic resection. Results: One hundred sixteen patients aged 43 +/- 17 years, 60 percent females, were included in the series. Median cyst diameter was 15 cm. Ten patients (8.6 percent) had complications. Three patients had an atelectasis, two had an acute bronchitis, one had a urinary tract infection, two had surgical wound infections, one developed a residual cavity and one had an eventration. During a median follow up of 95 months, no patient died and one had a recurrence of the disease. Conclusions: Surgery for uncomplicated hydatidosis has a low rate of complications.

Introducción: La cirugía de la hidatidosis hepática (HH) es habitual en hospitales del sur de Chile. El número de publicaciones relacionadas es escasa y los resultados disímiles. Hablar de morbilidad postoperatoria es complejo debido a la diversidad en la gravedad e implicancias para el paciente; basado en ello, Clavien publicó una clasificación basada en la gravedad de la morbilidad postoperatoria. El objetivo de este estudio es reportar la morbilidad postoperatoria en pacientes intervenidos por HH no complicada aplicando la clasificación de Clavien. Material y Método: Estudio de cohorte prospectiva. Se incluyeron pacientes intervenidos quirúrgicamente por HH no complicada, en el Hospital Hernán Henríquez Aravena de Temuco, entre 1997 y 2008. La variable resultado principal fue desarrollo de morbilidad postoperatoria aplicando la escala de Clavien. Otras variables de interés fueron estancia hospitalaria, mortalidad y recurrencia. Las técnicas quirúrgicas empleadas fueron periquistectomía total o subtotal y resección hepática. Se calcularon porcentajes, medidas de tendencia central y dispersión; intervalos de confianza de 95 por ciento e incidencia. Resultados: 116 pacientes, con mediana de edad de 40,5 años; 60,3 por ciento de género femenino. La mediana del diámetro quirúrgico promedio fue de 115,4 +/- 23,2 min. La incidencia de morbilidad fue de 8,6 por ciento; 90 por ciento de los cuales eran Grado I o II de Clavien. La etiología fue 5,2 por ciento de complicaciones médicas y 3,4 por ciento de complicaciones quirúrgicas. No se registró mortalidad. Con una mediana de seguimiento de 95 meses, se verificó recurrencia en 1 paciente, lo que representa una incidencia de 0,9 por ciento. Conclusiones: Se describe la morbilidad postoperatoria de una cohorte de pacientes con HH no complicada con énfasis en la gravedad de esta. La morbilidad observada es inferior a la publicada y de bajo nivel de gravedad.

Peritoneal hydatidosis: A review of seven cases.

Seven cases of peritoneal hydatidosis were reviewed. Of these, one had disseminated primary peritoneal echinococcosis, a rare presentation, whereas the rest were secondary to hepatic or splenic lesions. They were treated with a preoperative course of antihelminthics followed by surgery, which consisted of removal of the peritoneal cysts along with de-roofing and omentoplasty for the hepatic lesions and splenectomy for the splenic hydatid. During follow up, all patients were given a three-month course of albendazole and are doing well.

First Successful Puncture, Aspiration, Injection, and Re-Aspiration of Hydatid Cyst in the Liver Presenting with Anaphylactic Shock in Korea

Hydatid disease is a parasitic infestation caused by the larval form of Echinocococcus. In human, the most commonly affected organs are liver and lung. Most cysts remain clinically silent and are diagnosed incidentally or when complications occur. In Korea, hydatid disease is rare and surgically treated cases have been reported in the Korean literature. However, it is expected to confront this disease sooner or later, because of recent increase in traveling to the endemic area and industrial workers originating from those areas. With this trend, we experienced a case of hydatid cyst of the liver in a male patient from Uzbekistan. This patient was presented with anaphylactic shock combined with hydatid cyst. We successfully treated using ultrasound-guided transhepatic percutaneous drainage [termed puncture, aspiration, injection, and re-aspiration (PAIR)] of the hydatid cyst and concomitant albendazole instead of surgery. In this clinical case report, we describe all the course of the patient and recommend the PAIR as a first choice method for treatment of hepatic hydatid cyst.

Quiste hidatídico hepático a propósito de un caso

Se reporta el caso de paciente femenina de 51 años, con antecedente de contacto con animales domésticos, a la cual se le realizó diagnóstico de quiste hidatídico hepático, en base a estudios de imagen y paraclínicos compatibles por patrón ecográfico, con gran Lesión de Ocupación de Espacio (LOE) quística, multivesicular, de aspecto septado, en lóbulo hepático derecho, eosinofilia moderada y discreta elevación del perfil bioquímico hepático, con Elisa (IgG) para hidatidosis positivo, que manifestó buena respuesta a terapia farmacológica única con benzimidazoles (Albendazol) vía oral, con disminución progresiva de la lesión hasta su total desaparición, sin requerir tratamiento quirúrgico, en seguimiento actual de 13 meses. Se revisa la literatura de la enfermedad y manejo terapéutico de la misma.

We report the case of a 51 years old female patient, with a history of contact with domestic animals, to whom we diagnosed a Hepatic Hydatid Cyst, on the grounds of image studies and laboratory tests compatible with a spaceoccupying lesion, multivesicular cysts, in the right hepatic lobe; moderate eosinophilia, and a discreet elevation of the hepatic biochemical profile, with Elisa (IgG) positive for Hydatid Cyst disease. She showed a good response to single therapy with benzimidazole (Albendazole), given orally, with a progressive diminution of the lesion until its total disappearance, without requiring surgical treatment, at follow up for 13 months. We review the literature relative to this disease and its therapeutic options.
