Liver autotransplantation and atrial reconstruction on a patient with multiorgan alveolar echinococcosis: a case report.

BACKGROUND: Alveolar echinococcosis (AE) primarily affects the liver and potentially spreads to other organs. Managing recurrent AE poses significant challenges, especially when it involves critical structures and multiple major organs. CASE PRESENTATION: We present a case of a 59-year-old female with recurrent AE affecting the liver, heart, and lungs following two previous hepatectomies, the hepatic lesions persisted, adhering to major veins, and imaging revealed additional diaphragmatic, cardiac, and pulmonary involvement. The ex vivo liver resection and autotransplantation (ELRA), first in human combined with right atrium (RA) reconstruction were performed utilizing cardiopulmonary bypass, and repairs of the pericardium and diaphragm. This approach aimed to offer a potentially curative solution for lesions previously considered inoperable without requiring a donor organ or immunosuppressants. The patient encountered multiple serious complications, including atrial fibrillation, deteriorated liver function, severe pulmonary infection, respiratory failure, and acute kidney injury (AKI). These complications necessitated intensive intraoperative and postoperative care, emphasizing the need for a comprehensive management strategy in such complicated high-risk surgeries. CONCLUSIONS: The multidisciplinary collaboration in this case proved effective and yielded significant therapeutic outcomes for a rare case of advanced hepatic, cardiac, and pulmonary AE. The combined approach of ELRA and RA reconstruction under extracorporeal circulation demonstrated distinct advantages of ELRA in treating complex HAE. Meanwhile, assessing diaphragm function during the perioperative period, especially in patients at high risk of developing pulmonary complications and undergoing diaphragmectomy is vital to promote optimal postoperative recovery. For multi-resistant infection, it is imperative to take all possible measures to mitigate the risk of AKI if vancomycin administration is deemed necessary.

An unexpected case of an adnexal hydatid cyst in a pregnant woman: a case report.

BACKGROUND: Cystic echinococcosis, also known as hydatid disease, is a chronic and endemic illness caused by infection with a parasite called Echinococcus granulosus. In Romania, this disease has an incidence rate of 5.6 per 100,000 individuals, which is the highest in the Dobrogea region. The liver is the most affected site, accounting for 68.8% of cases, followed by the lungs at 17.2%. While cases of hydatid disease in the genital organs are rare, occurring at an incidence rate of only 0.5%, it is worth noting that cases of this disease in pregnancy worldwide are also rare, occurring at an incidence rate of 1 in 20,000 to 1 in 30,000 pregnancies. CASE REPORT: A 15-year-old Eastern-European woman who was 12 weeks pregnant presented to the emergency room with acute pelvic pain, dysuria, and frequent urination. Her laboratory tests showed that she had a urinary tract infection, and pelvic ultrasound revealed that she had a mass on her right adnexa. Despite receiving treatment, her symptoms did not improve, and she had to undergo surgery to remove the mass, which turned out to be a hydatic cyst. She also had to undergo a cesarean section to deliver her baby owing to fetal distress during labor. CONCLUSIONS: This medical case report provides a detailed description of a pelvic hydatid cyst that was discovered during pregnancy. What makes this case particularly noteworthy is the cyst's unusual location-it was found at the level of the right broad ligament of the uterus. Despite the complexity of the situation, the patient was able to receive effective treatment and the cyst was successfully managed with great outcomes for both the patient and the newborn. We hope that this report serves as a valuable example of how medical professionals can navigate challenging cases and provide optimal care for their patients.

Spleen-preserving surgery for splenic hydatid cyst: a case report.

Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

Cardiac cystic echinococcosis-A systematic review and analysis of the literature.

Human cystic echinococcosis (CE) is a parasitic infection caused by the larval stage of the tapeworm Echinococcus granulosus sensu lato, primarily affecting the liver and lungs. Although the heart is affected in only 0.02-2% of all CE cases, a considerable number of cases have been, and continue to be, published. However, due to the rare occurrence of cardiac CE and the resulting lack of clinical trials, knowledge about various aspects of the disease remains limited. To obtain a clearer picture of anatomical, clinical, diagnostic as well as therapeutic aspects of cardiac CE, we systematically reviewed the literature published between 1965 and 2022. The anatomical pattern of the affected cardiac structures follows the extension of the supplying capillary bed. The majority of patients (82.7%) are symptomatic and present with prolonged non-specific symptoms such as dyspnoea, chest pain and palpitations. Acute complications generally derive from cyst rupture, occur in 18.3% of cases and manifest as embolism, pericardial tamponade, or anaphylactic reaction in 83.2%, 17.8% and 10.9% of these cases, respectively. As for CE cysts localized in other organs, the diagnosis of cardiac CE is made by imaging. Serology plays a minor role due to its limited sensitivity. Unlike abdominal CE cysts, cardiac CE cysts are usually resected independent of their stage (active/inactive), because their presence impairs cardiac performance and carries the risk of long-term sequelae. More than 80% of patients are treated with a single surgical intervention. We found a disease-related case fatality rate of 11.1%. Since local recurrence was reported up to 108 months and secondary CE up to 72 months after surgery, patients should be followed up for a minimum of 10 years.

Exploring rare locations of hydatid disease: a retrospective case series.

INTRODUCTION: Hydatid disease, endemic in Mediterranean countries, primarily affects the liver, but can manifest in diverse organs. Non-hepatic and non-pulmonary cysts often pose diagnostic challenges. This study examines patients with hydatid cysts in atypical locations. METHODS AND RESULTS: From 2013 to 2020, our center treated 250 echinococcosis patients, among whom 11 cases (4.4%) with hydatid disease in uncommon sites were retrospectively reviewed. The distribution of unusual cyst locations and their clinical implications are discussed. CONCLUSION: Diagnosing hydatid cysts in uncommon locations is a formidable challenge. Surgeons should always contemplate the prospect of an unconventional cyst location when encountering patients with cystic masses in endemic regions. Failing to consider this possibility could lead to unfavorable outcomes.

Treatment of Cavernous Transformation of Portal Vein Caused by Hepatic Cystic Echinococcosis Using Ex Vivo Liver Resection and Autotransplantation.

BACKGROUND Hepatic cystic echinococcosis (HCE) is a frequently overlooked parasitic liver disease, for which the commonly recommended treatment is radical resection. However, this approach is often associated with severe comorbidities such as HBV/HCV, cirrhosis, and hepatic carcinoma, among others. CASE REPORT In this report, we present a case successfully managed by ex vivo liver resection and autologous liver transplantation (ELRA). In the described case, ex vivo resection was not feasible due to recurrent lesions and infections invading the portal vein, which resulted in portal vein cavernous transformation. CONCLUSIONS Through this paper, we aim to detail the treatment process, showcasing the feasibility and advantages of ELRA. Additionally, we propose a novel approach for the treatment of this disease, while emphasizing the importance of radical resection surgery to prevent long-term complications.

Multiple Cerebral Hydatic Cyst Developed After Operation of Cardiac Hydatic Cyst: A Case Report.

Hydatid cyst is a zoonotic disease and is an important health problem, especially in developing countries. Hydatic cysts are typically observed in the liver and lungs. Cardiac and brain involvement are rare manifestations. Cardiac hydatic cysts are usually located in the left ventricle. Brain involvement is frequently seen as a primary cerebral cyst and is almost always solitary. However, secondary intracerebral cysts are also seen as a result of cardiac cysts rupturing into the left ventricle spontaneously or iatrogenically, and these are usually multiple. Herein, we report a case that has two rare clinical manifestations of hydatid cysts.

Severe Hypernatremia During Hydatid Cyst Surgery: An Anusual Cause Of Acute Abdomen.

Treatment of liver hydatid cysts is still in most cases surgical. To avoid the recurrence of hydatid cysts injection of scolicidal products inside the cystic cavity is an important step in the surgical procedure. Many scolicidal solutions are used. Hypertonic Saline Solution (HSS) is widely used by surgeons; however, there is a risk of hypertonic saline resorption and acute hypernatremia. Iatrogenic hypernatremia can be life-threatening. We report three cases of hypernatremia secondary to HSS injection for hydatid cyst disease treatment. The objective of this study was to discuss the clinical features, and treatment of this rare complication.

Primary hydatid cyst of the spleen: A rare case report and literature review.

Hydatidosis is an endemic disease in certain areas in the world particularly in the Mediterranean, the Middle East, and South America, caused by a cestode known as Echinococcus granulosus. Humans are the accidental intermediate hosts. The liver and the lungs are the most commonly involved organ. If the parasite passes through the pulmonary capillary bed, the hydatid cyst may develop at any site in the body like bone, pancreas, brain, kidney, and orbit. Isolated spleen hydatid cyst is very rare. We hereby report one observation of isolated hydatid cyst of the spleen in a patient living in non-endemic area and without any potential risk.

Gossypiboma mimicking hepatic hydatid cyst after 22 years: a case report.

Gossypiboma is a non-absorbable material that is forgotten during surgery. These are medicolegal pathology that leads to diagnostic confusion from abscess to tumor. We present the case of gossypiboma detected in laparotomy in a 57-year-old male patient who had a history of operation due to a hydatid cyst 22 years ago and was referred to our center due to hydatid recurrence. The case should suggest a history of surgical gossypiboma, especially in asymptomatic patients. In this preventable pathology, the strategy during sur-gery and the careful and proper attitude of the surgical team are the main determinants.

A case of pediatric primary osteolytic extradural and complicated hydatid cyst revealed by a skull vault swelling.

Hydatidosis is a parasitic infestation whose etiological agent is the larva of the cestode Echinococcus granulosus. It is a zoonosis, and the human being behaves as an accidental intermediate host in the parasitic cycle with pediatric predominance. The most frequent clinical presentation is hepatic, followed by pulmonary, with cerebral hydatidosis being extremely rare. Imaging is characteristic, generally dealing with single cystic lesion, usually unilocular and less frequently multilocular, located mainly intraaxially. Extradural hydatid cyst, whether primary or secondary, remains very rare or even exceptional. The primary disease remains extremely rare, and its clinical picture is related to the number, size, and location of the lesions. Infection within these cerebral hydatid cysts remains an extremely rare occurrence, and only few cases were reported previously in the literature. The authors report the nosological review of the clinical, imaging, surgical, and histopathological records of a pediatric primary osteolytic extradural and complicated hydatid cyst in a 5-year-old North African male patient coming from a rural area who presented for progressive onset of a painless left parieto-occipital soft swelling without any neurological disorder with good outcomes after surgery. The authors report this case due the fact that it had not been documented before in the pediatric population and to the success of the specialized treatment.

The trajectory of anti-recEm18 antibody levels determines follow-up after curative resection of hepatic alveolar echinococcosis.

INTRODUCTION: Recurrence after curative resection of hepatic alveolar echinococcosis remains a clinical challenge. The current study tested if assessment of anti-recEm18 allows for postsurgical patient surveillance. METHODS: A retrospective study with patients undergoing liver resection for alveolar echinococcosis (n = 88) at the University Hospital Bern from 2002 to 2020 and at the University Hospital and Medical Center Ulm from 2011 to 2017 was performed. Analysis was directed to determine a potential association of pre- and postoperative values of anti-recEm18 with clinical outcomes. RESULTS: Anti-recEm18 had a linear correlation to the maximum lesion diameter (R2 = 0.558). Three trajectories of anti-recEm18 were identified based on a threshold of 10 AU/ml: "Em18-low" (n = 31), "responders" (n = 53) and "residual disease" (n = 4). The decline of anti-recEm18 in "responders" reached a plateau after 10.9 months at which levels decreased by 90%. The only patient with recurrence in the entire population was also the only patient with a secondary increase of anti-recEm18. CONCLUSION: In patients with preoperative elevated values, anti-recEm18 confirms curative surgery at 12 months follow-up and allows for long-term surveillance.

Early postoperative intra-axial dissemination of a pediatric extradural and complicated hydatid cyst.

Hydatid disease is very common around the Mediterranean basin and endemic in some parts of the world. Cerebral involvement remains rare, represents only about 2% of all hydatid localizations and mainly affects the pediatric population. Extradural hydatid cyst is very rare or even exceptional when it is associated with or followed by intracerebral disseminations. Here, the authors report a new exceptional case of an early multiple intra-axial hydatid dissemination in a 5-year-old North African male patient from a rural area who underwent surgery 3 months after a primary osteolytic extradural and complicated hydatid cyst with good clinical and radiological outcomes.
