Rare as hen抯 teeth: laparoscopic management of primary pelvic hydatid cyst

Hydatid disease is a zoonotic parasitic disease most frequently caused by echinococcus granulose Primary peritoneal hydatidosisis very rare. We report a case of primary hydatid disease of the intraperitoneal pelvic space.A 22-year-old male patient presented with a history of abdominal pain since 5 months. Abdominal examination revealed a smooth, firm, mildly tender, non-mobile lump in suprapubic region, on digital rectal examination, a smooth spherical mass was felt anteriorly and laterally outside the rectal wall, rectal mucosa was normal. All routine investigations including liver function tests were within normal limits Computed tomography scan of the whole abdomen showed giant cyst of 10� cm with multiple well-defined cysts in rectovesical pouch.Diagnostic laparoscopy was performed. The liver, spleen, mesentery, omentum was found to be normal. A large tense hydatid cyst was noted in the pelvic cavity.Partial peri-cystectomy with endo-cystectomy was performed. Postoperative period was uneventful and patient was discharged on 4th postoperative day.Primary intra-abdominal but extra-peritoneal localization has been reported in only 0.2-2% cases making it a very rare entity.The treatment of choice for pelvic hydatid cyst is principally a careful surgical excision. Here with minimum invasive technique this case was operated and results were excellent

Application and prospect of Bayesian spatio-temporal model in the study of hydatid disease / 中华地方病学杂志

With the development of computer technology and the abundance of spatio-temporal data, Bayesian spatio-temporal model (BSTM) has been developed rapidly, and wildly used by academics to investigate the spatial epidemiological feature of infectious diseases. Hydatid disease is a global natural focus disease that seriously endangers human health. Its epidemic process is complex and affected by many factors. BSTM provides a new method for study of hydatid disease. By modeling, we can not only analyze the influencing factors of hydatid disease, but also can predict the epidemic trend and make the disease distribution map, which is of great significance to public health decisionmaking. Based on a comprehensive review of the literatures, this paper expounds the principles, types and application status of BSTM in hydatid disease.

Intramuscular hydatid cyst in the lower extremity: report of three cases

Abstract Hydatid cysts are rarely detected in the muscle tissue, even in endemic countries. Echinococcus granulosis is the most common causative agent, whereas Echinococcus alveolaris is rare. Three patients, two females and one male, with primary echinococcosis of the skeletal muscles are described in this report. Mean patient age was 33.3 ± 14.6 years. The disease occurred as soft tissue masses in all three patients, and no hydatid foci were detected elsewhere in the patients. Skeletal muscle echinococcosis should be considered in the differential diagnosis of limb masses, especially in endemic countries.

Unusual hydatid cysts: cardiac and pelvic-ilio femoral hydatid cyst case reports and literature review

Abstract Introduction: Hydatid cyst is a parasitic disease caused by Echinococcus granulosus, most commonly seen in the liver and lungs. The hydatid cyst is rarely seen in the heart and iliofemoral region, representing less than 2% of all cases. In this article, we report our cases of hydatid cysts in unusual loci. Methods: Between 2015 and 2018, 6 rare cases of hydatid cysts were diagnosed at the Cardiovascular Surgery Department of Harran University. Four of these patients had cardiac localization and two patients had their cysts located in the iliofemoral region, extending to the pelvic zone. All patients were female. Three patients had no other organ involvement. One patient with cardiac hydatid cyst underwent normothermic cardiopulmonary bypass + total pericystectomy + Cooley-like aneurysmectomy. Total pericystectomy was performed in three other patients with intrathoracic locus by normothermic cardiopulmonary bypass. Two patients who were referred to our clinic with palpable iliofemoral mass were evaluated with appropriate imaging methods and diagnosed accordingly. Multiple iliofemoral cysts were managed with pericystectomy and drainage by a single incision made over the inguinal ligament. Conclusion: Hydatid cyst disease can develop in cardiac chambers and inguinal region with or without hepatic or pneumatic involvement. Normothermic cardiopulmonary bypass can be safely used in patients with cardiac hydatid cysts, and capitonnage similar to ventricular aneurysm repair in patients with a widely involved cystic lesion can be very useful for the protection of ventricular functions.

Primary hydatid cyst of the pterygomandibular region: an unusual cyst, location and case report

Hydatid disease is a zoonotic infection in humans. The disease is endemic in some parts of the world, including Africa, Australia, and Asia, where cattle grazing is common; the disease is spread by an enteric route following the consumption of food contaminated with the eggs of the parasite. Failure to identify this parasite results in delayed diagnosis and increased morbidity to the patient. Upon diagnosis, every possible step should be taken, both surgical and medical, to prevent anaphylactic reactions from the cystic fluid. Postsurgical long-term follow up along with periodical ultrasonography of the liver and computed tomography scan of the abdomen is essential to rule out possible recurrence.

A Case Of Primary Pulmonary Echinococcosis Presenting As Left Sided Gross Pleural Effusion

Invasion of the human lungs by the larvae of the dog tapeworm Echinococcus granulosus (pulmonary cystic echinococcosis, PCE) is an incapacitating disease, frequently found across a wide geographic area, CE is endemic in many parts of the world, particularly the Mediterranean countries, Central Asia including the Tibetan Plateau, Northern and Eastern Africa, Australia, and South America. [1] Global burden of the human AE is approximately 18,235 new cases per annum with the majority (91%) occurring in China. [2] We report a case of 17–year–old girl student who presented with complaints of left sided pleuritic chest pain, fever and dyspnoea. X–ray chest PA view revealed gross pleural effusion on left side that was exudative in nature and did not respond to antibiotics and anti–tuberculous therapy. HRCT chest revealed large loculated cystic lesion showing calcification in left upper lobe parenchymal region suggestive of ruptured hydatid cyst. IgG antibody for E granulosus was positive. Ultrasound scan of abdomen and pelvis were within normal limits. A diagnosis of Primary pulmonary echinococcosis was made. She was treated successfully with Albendazole 400 mg bid for 21 days; six such cycles 14 days apart

Hidatidosis cerebral: comunicación de seis casos pediátricos / Cerebral hydatid disease: report of six pediatric cases

Hydatid disease is a parasitic infection whose etiologic agent is Echinococcus granulosus. Human is an accidental intermediate host and the most common site is the liver. The brain involvement is unusual and up to 75% of cases are described in the pediatric population. We present six children with cerebral hydatid disease admitted to the Pediatric Hospital J.P. Garrahan. All had neurological involvement on admission. The images showed single cystic lesion in the brain. They did not present involvement in other organs. Serology was negative in all cases. Medical and surgical treatment in all cases. The clinical outcome was favorable without sequelae in five of them and one had a residual paresis right faciobrachiocrural. This infection should be considered in the differential diagnosis of cystic tumor lesions of the central nervous system.

Objective To report the integrated progress of the hydatid disease information management system,and to pro-vide the reference for further system improvements by analysis of results on simulation test feedback. Methods The work of in-stitutional code matching by collecting fundamental and integrated information of the system in epidemic areas of hydatid disease was carried out,and professional control agencies were selected to carry out the simulation test. Results The results of agen-cies code matching at stage indicated the average completion rate was 94.30% on administrative agencies,69.94% on registered professional agencies and 56.40% on professional institutions matching related to hydatid disease prevention and control imple-ments in seven provinces(autonomous regions)and Xinjiang Production and Construction Corps. Meanwhile,the response rate of open-ended proposals was 93.33% on fifteen feedbacks,and the statistics showed 21.43% believed the system was low fluen-cy,64.29% considered the system was inconvenience for data inputs and 42.86% considered it would be improved on system sta-tistics functions,of which 27.78% were provincial users,22.22% were the city users and 50.00% were the county users. Con-clusion The hydatid disease prevention information management system meets the fundamental needs of the majority agencies in hyperendemic areas of echinococcosis,it needs to develop the further test with more agencies joining after the work of the in-stitutional code matching completion and the system service improvement in the next stage.

Application of ERCP in treatment for biliary complications of hepatic hydatid disease / 中国内镜杂志

Objective To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) in treatment for biliary complications of hepatic hydatid disease. Methods From October 2010 to October 2016 , 27 patients who were admitted for hepatic hydatid disease underwent therapeutic ERCP pre- or post-operation, then we retrospectively analyzed the clinical manifestations, laboratory tests, imaging examinations, ERCP methods and therapeutic effects in perioperative period of ERCP. Results All the 27 patients who underwent ERCP pre-or post-operations because of biliary complications of hepatic hydatid disease obtained good treatment effect. There were some reasons for ERCP, 12 cases for acute suppurative cholangitis and obstructive jaundice caused by intrabiliary rupture and 7 for severe jaundice compress by large hepatic hydatid cyst, whereas 6 cases for biliary fistula and 2 for biliary stricture after operation. 6 indexes including white blood cell count (WBC), aspertate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) were significantly different between 24 hours pre- and 48 hours post- ERCP (P < 0.05), all the patients were improved after operation. Conclusion ERCP which is performed at pre- or post- operation may be an effective treatment for biliary complications of hepatic hydatid disease such as acute suppurative cholangitis, biliary fistula and stricture.

Treatment efficacy and safety of ultrasound-guided puncture combined with surgical resection for liquefied cavitary hepatic alveolar echinococcosis / 中华肝胆外科杂志

Objective To study the safety and efficacy of ultrasound-guided puncture combined with surgical resection for liquefied cavitary hepatic alveolar echinococcosis (HAE).Methods A retrospective study was conducted on 17 patients who had liquefied cavitary HAE and were treated at the Affiliated Hospital of Qinghai University from January 2014 to August 2016.Ten patients were treated with ultrasound-guided puncture combined with surgical resection (the case group),and 7 patients were treated with resection (the control group).The basic characteristics,operation time,blood loss during operation,preoperative and postoperative laboratory tests and complications were compared between the 2 groups.Results There were no significant differences between the 2 groups in basic characteristics,such as age,gender,and lesion diameter (P ＞ 0.05).The operation time and blood loss during operation showed significant differences between the 2 groups,(308.0 ± 23.0) min (389.0 ± 95.7) min and (1 360.0 ± 182.9) ml vs.(1 607.1 ± 205.0) ml,respectively (all P ＜ 0.05).The prothrombin time (PT) after day 3 of operation and alanine aminotransferase level after day 5 of operation showed significant differences between the 2 groups,(13.8 ±0.9) s vs.(15.5 ±1.7) s and (81.9 ±20.9) U/L vs.(108.1 ±29.5) U/L,respectively (all P ＜ 0.05).There was no significant difference in postoperative complications between the 2 groups.Conclusions Ultrasound-guided puncture combined with surgical resection shortened the operation time,reduced blood loss and avoided serious complications after surgery.This treatment is efficacious and safe for liquefied cavitary HAE.

"Double ""T"" tube drainage in hepatic echinococcosis which ruptured into the common bile duct" / 中华肝胆外科杂志

Objective To investigate the double T tube drainage method in the treatment of hepatic echinococcosis which ruptured into the common bile duct.Methods A retrospective study was conducted on 86 patients who were treated surgically for hepatic echinococcosis which had ruptured into the common bile duct at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to December 2014.The average postoperative hospitalization,postoperative complications (residual cavity bile leakage and residual cavity effusion,residual cavity infection) and biliary complications of biliary tract infection were analyzed.Results Significant differences were found on the postoperative residual cavity complications in group A:(2,7.1％) when compared with Group B:(9,15.5 ％),and also on the postoperative hospitalization between the double T tube drainage group [group A:(7.1 ± 1.3) d] and the traditional T type tube decompression group [B group:(8.2 ± 1.5) d] (P ＜ 0.05).Conclusions The doubleT tube drainage in the treatment of hepatic echinococcosis which had ruptured into the common bile duct was simple,safe and effective.This treatment could completely cure residual cavity bile leakage,and it had the advantage of avoiding occurrence of common bile duct related complications caused by the traditional suture method for bile leakage.

Primary Giant Splenic and Hepatic Echinococcal Cysts Treated by Laparoscopy

Cystic echinococcosis is a zoonosis caused by the larval stage of Echinococcus granulosus. Liver and lungs are the most commonly affected organs whereas splenic infection is rare and its primary involvement occurs in less than 2% of cases. We report a case of primary giant splenic and hepatic hydatid cyst in a 28-year-old woman who was admitted for upper right quadrant pain. The abdominal ultrasonography and computed tomography showed two cystic tumors with hydatid features in liver and spleen. Total splenectomy was performed for the splenic cyst and partial pericystectomy with drainage for the liver cyst using a laparoscopic approach. One drain was kept in place for two months due to a biliary leak of about 20 ml/day and removed afterward. The patient was discharged on postoperative day 7. Laparoscopic approach for patients with concomitant splenic and hepatic hydatidosis is a safe and effective option.

Control programme for cystic echinococcosis in Uruguay

Cystic echinococcosis is a highly endemic parasitic zoonosis that is present in the Southern Cone countries of America. For several decades, various prevention and control programmes have been implemented in different countries and regions, with varying results. In Uruguay, a new control programme was implemented in 2006 that employed new strategies for canine diagnosis and treatment, dog population control, diagnosis in humans, epidemiological surveillance, and health education, including community participation. The control programme in Uruguay addresses the control and surveillance of the disease from a holistic perspective based on Primary Health Care, which has strengthened the community’s participation in developing and coordinating activities in an interdisciplinary manner. Similarly, the control programme that is currently implemented is based on a risk-focused approach. The surveillance and control measures were focused on small villages and extremely poor urban areas. In this study, the strategies used and the results obtained from 2008-2013 are analysed and discussed.

Complete Resolution of Bilateral Pulmonary Hydatid Cysts with Prolonged Administration of Albendazole: A Rare Occurrence

Hydatid disease is a zoonotic disease caused by Echinococcus species. Echinococcus granulosus is the most common species which is responsible for hydatid disease in the humans who act as accidental intermediate hosts in the life cycle of the parasite. Pre-operative albendazole therapy followed by surgery is the mainstay of treatment for pulmonary and hepatic hydatid cyst at present. Not much data is available to support the sole use of albendazole for complete cure apart from its usage for those patients who have refused surgery or cannot undergo surgery because of any reason. We hereby report the case of a 12 year old female patient who was diagnosed with bilateral pulmonary hydatid cysts that responded well to Albendazole 15mg/kg /day given for a period of nine months with a drug free interval of one week every month. There was complete clinical and radiological resolution of hydatid cyst after the treatment. There has been no recurrence on follow-up of one year.

Evaluation on application of China Disease Prevention and Control Informa-tion System of Hydatid DiseaseⅠCurrent status at the provincial level / 中国血吸虫病防治杂志

Objective To evaluate the application status of China Disease Prevention and Control Information System of Hy?datid Disease,in which questions existed are summarized in order to promote the system update. Methods A questionnaire was designed and distributed to Inner Mongolia,Sichuan,Tibet,Gansu,Qinghai,Ningxia,Xinjiang and Xinjiang Production and Construction Corps to evaluate the application status of China Disease Prevention and Control Information System of Hydatid Disease assistant with telephone. Results The recovery rate of questionnaires was 87.5%. The statistics of closed questions showed that national application rate of the China Disease Prevention and Control Information System of Hydatid Disease was 100%,of which 15.3%were low frequency users,57.1%believed the system was necessary,28.6%considered it was dispens?able,and 14.3%believed that it was totally unnecessary. The statistics of open?ended questions indicated that 6 endemic regions suggested to increase the guidance and training,while 4 endemic regions had opinions on sharing the information of the national infectious disease reporting systems and hydatid disease prevention and control information system,and the opinions on turning monthly report to quarterly report,and increasing statistics and analysis module,and 3 endemic regions deemed that the system had logic errors and defects. Conclusion The problems of the system are mainly focused on the existence of systemic deficien?cies and logic errors,lacking of statistical parameters and corresponding analysis function module,and lacking of the guidance and training,which limits the use of the system. Therefore,these problems should be resolved.

Hydatid cystic disease at unusual sites

Hydatid disease is a zoonotic infection caused by Echinococcus granulosus, which belongs to phylum Platyhelminthes. It is endemic in many parts of the world including India. Though Hydatid disease commonly occurs in liver and lung no organ or tissue is immune in the body. When it presents in unusual sites Hydatid disease often poses a diagnostic challenge. A high index of suspicion, comprehensive radio imaging investigations are often required to evaluate these cases. In the study we have conducted for 4 years, we reported a total no of 7 Hydatid cases that presented at unusual sites. Most common rare presentation in our study was renal hydatid disease, 3 cases; and one each in pancreas, Spleen, peritoneum and pelvis.

The impact of combined laparoscopic and choledochoscopic treatment on biliary leak in hepatic hydatid disease in a high attitude region / 中华肝胆外科杂志

Objective To explore the impact of combined laparoscopic and choledochoscopic treatment on bile leak in hepatic hydatid disease at a high attitude region.Methods The clinical data of 50 patients who underwent combined laparoscopic and choledochoscopic treatment were compared with 50 patients who underwent laparoscopic surgery alone for hepatic hydatid internal capsule excision surgery.Results In the combined laparoscopic and choledochoscopic group,the incidence of biliary fistula after surgery was 15％,the incision infection rate was 13％,the length of hospitalization was (11.6 ± 3.8) days and the postoperative time to take off drain was (14.3 ± 7.9) days.These were significantly better than those in the laparoscopic alone group.The operation time in the former group was (108.2 ± 28.4)min,which was slightly longer than the laparoscopy group.Conclusion The combined laparoscopic and choledochoscopic treatment is a safer therapeutic option in treating hepatic hydatid disease with less trauma,faster recovery and shorter hospital stay than laparoscopic surgery alone in a high attitude region.
