ABSTRACT
Background: Cystic echinococcosis is a zoonosis caused by the parasite Echinococcus granulosus. The disease rarely occurs in Norway, but constitutes a significant global health issue. Case presentation: A man in his forties presented with right-sided flank pain. CT scan of thorax and abdomen revealed a 10 cm cystic lesion in the liver, suggestive of cystic echinococcosis. Serological test for specific antibodies was positive. Before transfer to a tertiary centre for liver surgery, he developed a cough. Repeated CT scan of thorax and abdomen showed perforation of the liver cyst through the diaphragm and into the right lung. He underwent a thoracolaparotomy and en bloc resection of liver segments 5, 7, 8, adjacent part of the diaphragm, and right lower and middle lung lobe. Interpretation: With increasing immigration, we believe it is imperative for healthcare professionals in regions with low prevalence of cystic echinococcosis to consider the possibility of this disease when encountering patients with unexplained liver cysts and relevant exposure.

BACKGROUND: Cystic echinococcosis (CE) is a zoonotic disease with an Africa-wide prevalence of 1.7%. CE is caused by the tapeworm Echinococcus granulosus sensu lato, with the liver being the most commonly affected organ. In South Africa (SA), there is a paucity of data on liver CE demographics and management. OBJECTIVES: To describe the demographics and clinical profile of patients with liver CE in a single tertiary hospital in Eastern Cape Province, SA. METHODS: A 4-year (2019 - 2022) retrospective clinical record review study was conducted on patients presenting with liver CE to the Department of Surgery at Frere Hospital. The demographics, clinical characteristics and management of patients with liver CE are reported. RESULTS: A total of 56 patients diagnosed with and managed for liver CE were included in the study. The mean age of the patients was 37.5 years. Abdominal pain (n=39; 69.6%) was the most common presenting symptom, and a palpable abdominal mass (n=36; 64.3%) was the predominant presenting sign. Most patients had disease confined to the liver (n=35; 62.5%). The right lobe of the liver was most commonly affected (n=38; 67.9%), and most patients had a single liver cyst on imaging (n=32; 57.1%). The majority of the patients (n=36; 64.3%) were managed with surgical partial cystectomy, with a perioperative bile leak being the most common complication. CONCLUSION: In our setting, liver CE contributes to a significant local burden of the disease. The disease often has a nonspecific clinical presentation, necessitating imaging for the diagnosis. We observed good short-term outcomes in patients managed with combined partial cystectomy and medical therapy, although there is a risk of perioperative bile leak.

BACKGROUND Hydatid disease is a common parasitic infection in many areas of Asia, South America, and Africa. It can affect any organ, most commonly the liver. The hydatid is often asymptomatic and the diagnosis is made when complications arise. The most common complication of this disease is opening in the bile ducts, which is a life-threatening condition causing serious acute cholangitis. We report a case of acute cholangitis caused by hydatid cyst rupture into the right bile duct. CASE REPORT A 33-year-old woman, with no medical or surgical history, presented to our Emergency Department with abdominal pain, jaundice, and fever for 3 days prior to admission. The patient was hemodynamically stable. In the examination, we noticed right upper-quadrant tenderness with guarding, icterus sclera, and negative Murphy sign. A CT scan showed a liver hydatid cyst of the 4th and 8th of segments, with intrahepatic and extrahepatic biliary duct dilation. The cyst communicated with the right hepatic bile duct via a large fistula. A diagnosis of acute cholangitis was made and she underwent conservative treatment with external drainage of the pericystic cavity through the biliary duct. The postoperative course was uncomplicated and she was discharged 15 days later. CONCLUSIONS The surgical approach to hepatic hydatid must be customized based on the specific characteristics of the cyst and associated complications. Acute hydatid cholangitis is a rare but serious complication of a hydatid cyst, which requires early diagnosis and adequate surgical management.

INTRODUCTION: Alveolar echinococcosis is an endemic parasitic disease prevalent in certain cold regions of the Northern Hemisphere, including Eastern France, Switzerland, Germany, Canada, and the United States. Widely underdiagnosed, it is associated with infection by Echinococcus multilocularis, a small tapeworm belonging to the cestode class, capable of causing multi-systemic involvement, particularly in elderly or immunocompromised patients. CASE REPORT: We present the case of an 82-year-old patient, immunocompromised due to prolonged corticosteroid therapy and treatment with dupilumab. She was referred to our department for a diagnostic assessment of atypical hepatic and pulmonary lesions, initially suspected of tuberculosis or an IgG4-related disease. The hypothesis of alveolar echinococcosis caused by E. multilocularis was eventually considered based on a set of arguments, further confirmed by molecular diagnosis. We discuss the role of dupilumab in the systemic evolution and atypical presentation of the disease, through the induction of a specific immunosuppression. CONCLUSION: Alveolar echinococcosis should be systematically considered in case of systemic disease with prominent hepatic and pulmonary involvement, especially in immunocompromised patients.

BACKGROUND: Alveolar Echinococcosis (AE) is a malignant zoonotic disease caused by Echinococcus multilocularis infection. Considering whether the lesion is accompanied by vascular invasion (VI) is crucial for treatment strategies. A cost-effective and convenient clinical diagnostic method is urgently needed to supplement current techniques. Consequently, we detected soluble CD155 (sCD155) as a potential biomarker for diagnosing VI in hepatic alveolar echinococcosis (HAE). METHODS: Blood samples were from 42 AE patients and 49 healthy controls (HCs). Based on the computed tomography (CT) and contrast-enhanced CT, AE patients were further categorized into HAE with VI (VIAE; 27 cases) and HAE without VI (NVAE; 15 cases). The sCD155 concentration was measured by an enzyme-linked immunosorbent assay (ELISA). Correlations between sCD155 expression levels and clinicopathological features of AE patients were analyzed using SPSS and GraphPad Prism software. RESULTS: The sCD155 concentrations in AE patients were significantly higher than in HCs. The serum sCD155 level significantly differed between the VIAE and NVAE groups. The univariate analysis showed that VI of AE was significantly correlated with the sCD155 level when the sCD155 was greater than 11 ng/mL. After adjusting for potential confounding factors, the multivariable analysis showed that sCD155 had an independent effect on VI of HAE. The receiver operating characteristic (ROC) curve showed that sCD155 could differentially diagnose VI of HAE at the cut-off value of 11.08 ng/mL with an area under the curve (AUC) value of 0.75. The sensitivity and specificity were 74.07 % and 66.67 %, respectively; the positive and negative predictive values were 74.07 % and 60.00 %, respectively. CONCLUSION: The sCD155 could be a VI biomarker for HAE. Elevated sCD155 levels are indicative of an increased likelihood of concomitant VI in HAE patients, necessitating a thorough evaluation of vascular impairment and the formulation of individualized management strategies.

BACKGROUND Hepatic hydatid cyst disease, caused by the parasite Echinococcus granulosus, is endemic in certain rural areas of the world, but not in most of East Asia outside Mainland China. In Taiwan, only one autochthonous case has been reported over the past 40 years. We present the case of an urban 91-year-old female patient without international travel history for more than 40 years. CASE REPORT The 91-year-old woman who used a wheelchair came to the Emergency Department reporting melena for 2 days and 1 episode of coffee-grounds vomitus. Epigastric tenderness was present. An incidental finding of elevated liver enzymes along with the clinical picture prompted further survey. Computed tomography revealed a 14×10×12 cm homogeneous cystic lesion in the right hepatic lobe with a partially calcified wall. On sonograms, a similar lesion was found, and the pathognomic "water-lily" sign was visualized along with the isoechoic-to-hypoechoic internal septa, fulfilling the diagnosis despite the patient's refusal to undergo magnetic resonance imaging studies and invasive definite diagnostic procedures. Although anthelmintic chemotherapy and invasive therapeutic measures were also refused, her symptoms improved and was not recurrent under supportive measures. However, the cyst was still present 12 months after discharge. CONCLUSIONS The case highlights that in areas with few cases of hepatic hydatid disease, the accurate diagnosis could be missed in patients without a significant epidemiological history. However, once imaging findings, especially those that are pathognomic, are appropriately interpreted on at least 2 imaging modalities, such cases could be diagnosed without further definitive studies.

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.

Cystic echinococcosis (CE) is a worldwide helminthic zoonosis causing serious disease in humans. The WHO Informal Working Group on Echinococcosis recommends a stage-specific treatment approach of hepatic CE that facilitates the decision on what therapy option is most appropriate. Percutaneous aspiration, instillation of a scolicide, e.g., ethanol or hypertonic saline, and subsequent re-aspiration (PAIR) have been advocated for treating medium-size unilocular WHO-stage CE1 cysts. PAIR can pose a risk of toxic cholangitis because of spillage of ethanol in the case of a cysto-biliary fistula or of life-threatening hypernatriaemia when hypertonic saline is used. The purpose of our study is to develop an alternative, safe, minimally invasive method to treat CE1 cysts, avoiding the use of toxic topic scolicides.We opt for percutaneous drainage (PD) in four patients: the intrahepatic drainage catheter is placed under CT-fluoroscopy, intracystic fluid is aspirated, and the viability of intracystic echinococcal protoscolices is assessed microscopically. Oral praziquantel (PZQ) is added to albendazole (ABZ) instead of using topical scolicidals.Protoscolices degenerate within 5 to 10 days after PZQ co-medication at a cumulative dosage of 250 to 335 mg/kg, and the cysts collapse. The cysts degenerate, and no sign of spillage nor relapse is observed in the follow-up time of up to 24 months post-intervention.In conclusion, PD combined with oral PZQ under ABZ coverage is preferable to PAIR in patients with unilocular echinococcal cysts.

BACKGROUND: The organ most commonly invaded in echinococcosis is the liver; the lungs, brain, kidneys, heart, and spleen are rarely invaded, and multi-organ involvement in echinococcosis is even rarer. No studies have reported renal invasion after liver transplantation for hepatic alveolar echinococcosis. CASE PRESENTATION: We report here a case of renal invasion 2 years after allogeneic liver transplantation in a 53-year-old female patient with hepatic alveolar echinococcosis combined with lung metastases. At the time of the first consultation, the lesion had been found to involve the second hepatic hilum combined with lung metastases, but the patient requested conservative treatment, and the lesion was not controlled by taking albendazole for 3 years. After discussion in the treatment group, it was decided to use allogeneic liver transplantation and lung segmental resection for surgical treatment, after which the patient was put on long-term oral immunosuppression. She was hospitalized 2 years later for low back pain and diagnosed with renal alveolar echinococcosis. Due to significant compression and left-sided renal insufficiency, the final option was to remove the diseased kidney. It is worth mentioning that signs of unexplained urinary tract infection were present throughout the course of treatment. CONCLUSION: This study suggests that extra attention should be paid to the presence of cryptogenic lesions in patients with hepatic alveolar echinococcosis who already have definite metastatic lesions. Immunosuppressive drugs after liver transplantation in patients with hepatic echinococcosis may cause occult lesions to develop into active ones. In clinical practice, particular attention should be paid to patients with hepatic alveolar echinococcosis with long-term concomitant signs of unexplained urinary tract infections, which may be a precursor clinical feature of cryptogenic renal alveolar echinococcosis.

BACKGROUND: Endocystectomy is a conservative surgical approach to managing cystic echinococcosis. Bile leakage is the main complication of this technique. The aim of this study was to evaluate the factors associated with bile leakage and to assess the outcomes and cost efficiency of strategies used to treat bile leakage. METHODOLOGY/PRINCIPAL FINDINGS: Patients who underwent endocystectomy between 2005 and 2020 were included. The preoperative characteristics, intra- and postoperative outcomes, hospital costs, and cost efficiency (the Diagnosis-Related Group reimbursement minus the overall cost) were evaluated prospectively. A total of eighty patients with 142 cysts were included. Postoperative complications occurred in 17 patients (21%), including 11 patients with bile leakage (type A: 1, type B: 6 and type C: 4 patients, total 13%). Bile leakage was more frequent in patients with preoperative MRI signs of cysto-biliary fistulas or intraoperative visible cysto-biliary fistulas (p = 0.03 and p = 0.04, respectively) and in patients with cysts larger than 8 cm (p = 0.03). Patients with bile leakage who underwent reoperation (type C) had significantly shorter hospital stays (9 vs. 16 days, p<0.01) and better cost efficiency than those who received radiologic or endocscopic interventions (2,072 vs. -2,097 p = 0.01). No mortality was observed, and recurrence was seen in two patients. CONCLUSIONS/SIGNIFICANCE: Endocystectomy is a safe and efficient technique. Preoperative and intraoperative cysto-biliary fistulas and a cyst diameter larger than 8 cm are correlated to postoperative bile leakage. Early operative management of bile leakage reduces hospital stay and improves cost efficiency compared with radiologic or endoscopic treatments.

PURPOSE OF REVIEW: The aim of our review is to summarize specific clinical, diagnostic and treatment aspects of pulmonary cystic echinococcosis. The lung is the organ second most affected by cystic echinococcosis with approximately a quarter of cystic echinococcosis cysts. Most cysts are in the liver. Apart from the watch and wait approach for selected inactive cysts [cystic echinococcosis CE4, CE5], the well established WHO cystic echinococcosis cyst classification-based treatment of hepatic cystic echinococcosis cannot be applied to pulmonary cystic echinococcosis cysts. Some standard interventions can even be harmful when applied to pulmonary cystic echinococcosis cysts. RECENT FINDINGS: Cystic echinococcosis is one of the neglected tropical diseases (NTDs). Development of new diagnostics and treatment modalities is hampered by low investment into research and is accordingly slow. SUMMARY: Surgery is the mainstay of treatment for pulmonary cystic echinococcosis cysts. Parenchyma-sparing surgical techniques should be used whenever possible. Albendazole induces decay of the parasitic cyst membrane, opening of cystobronchial fistulas and cyst complications, which can be life threatening. It is strongly recommended to seek advice from expert centres, including differential diagnoses, treatment and a long-term management plan.

OBJECTIVE: Alveolar echinococcosis (AE) is a parasitic liver disease with infiltrative growth similar to solid organ malignancies. Major vascular damage is frequent and often remains untreated until catastrophic events precipitate. Detailed clinical and radiological assessment is required to guide individualised treatment decisions. Standardised radiological reporting templates of malignancies with profiles resembling AE are candidates for adaptation. Our objectives are to describe vascular pathology in AE and establish a framework for structured evaluation as the basis for treatment decisions and monitoring. DESIGN: Retrospective case series. RESULTS: 69 patients (37.1%) had vascular involvement: portal vein (PV) 24.7%, hepatic vein (HV) 22.6% inferior vena cava (IVC) 13.4%. Significant stenosis/occlusion of vessels was present in 15.1% of PV, in 13.4% of HV and in 7.5% of IVC involvement. Vascular pathology needing specific treatment or monitoring was present in 8.6% of patients. The most frequent clinical presentation was high grade IVC stenosis or occlusion which was seen in 11 patients of the cohort. CONCLUSION: Advanced AE requires early multidisciplinary assessment to prevent progressive impairment of liver function due to vascular damage. The focus at first presentation is on complete evaluation of vascular (and biliary) involvement. The focus in non-resectable AE is on prevention of vascular (and biliary) complications while suppressing growth of AE lesions by benzimidazole treatment to improve the quality of life of patients. We developed a framework for standardised vascular assessment and follow-up of patients with AE to recognise and treat complications early.

PURPOSE OF REVIEW: This work aims to provide an update of knowledge on the evolution of inactive cystic echinococcosis (CE) cysts (CE4-CE5) managed by 'watch-and-wait', by means of a scoping review of the literature published after the publication of the WHO-IWGE (Informal Working Group on Echinococcosis) Expert Consensus document in 2010. RECENT FINDINGS: A total of 31 articles were included. Population ultrasound-based studies showed that spontaneously inactivated CE cysts represent 50.2% (95% confidence interval 38.7-61.8) of all detected untreated CE cysts, and that the prevalence of CE4-CE5 cysts tends to increase with age. Four longitudinal population-based studies showed that CE cysts naturally tend to evolve towards inactivation and that spontaneously inactivated cysts reactivate in a minority of cases. This was confirmed by four hospital-based studies, showing that spontaneously inactivated cysts reactivate rarely, while rate of reactivation is higher if inactivity was obtained posttreatment. It was not possible to drive conclusions on any difference in the clinical course of infection in immunocompromised or pregnant patients. SUMMARY: CE cysts tend to evolve spontaneously to inactivation over time. The published literature supports the safety of the watch-and-wait approach for inactive cysts, sparing treatment to a substantial proportion of asymptomatic patients. A regular follow-up with ultrasound of all inactive cysts is required to detect reactivations.

BACKGROUND: Liver hydatid cyst affects approximately 95% of the world's echinococcosis cases. Despite advances in treatment, the recurrence rate remains high and is influenced by several factors that are yet to be determined. The objective of this study was to identify the predictive factors of liver hydatid cyst recurrence following surgery in children and to establish a treatment regimen aimed at preventing this postoperative morbidity. METHODS: A bi-centric retrospective descriptive and analytic study was conducted involving 122 children who underwent surgery for liver hydatid cysts between January 1st, 2009, and December 31st, 2017. All factors that could potentially contribute to recurrence were thoroughly investigated. The data was processed using SPSS.v21, and a significant level of p-value 0.05 was applied. RESULTS: Out of the 122 children, 20 patients experienced cyst recurrence (16.39%). Among them, there were nine girls and eleven boys. The median time of recurrence was 16.5 months. Abdominal ultrasonography demonstrated efficacy in detecting recurrence. Several factors were identified as predictors of postoperative recurrence, including intimate contact of the hydatid cyst with the large vessels (p = 0.031), intraperitoneal effusion (p = 0.042), bile duct dilation (p = 0.032), and postoperative spontaneous discontinuation of medical treatment (p = 0.010). Among these factors, two independent risk factors for recurrence were identified: intimate contact of the hydatid cyst with the large vessels (p = 0.011) and the presence of an intraperitoneal effusion (p = 0.018). CONCLUSION: Our study has identified several predictors of postoperative recurrence, including two previously undocumented risk factors in the literature. Awareness of these risk factors can assist surgeons in implementing preventive measures to avoid the recurrence of hydatid cysts. LEVEL OF EVIDENCE: Prognosis study Level II.

BACKGROUND: Hydatid cyst is an endemic zoonotic infection that annual incidence ranges from <1 to 200 per 100,000 individuals. The most common complication of hepatic hydatid cyst reported is rupture of the cysts, most commonly intrabiliary rupture. Direct rupture to hollow visceral organs is rarely seen. We describe here an unusual cystogastric fistula in a patient with liver hydatid cyst. CASE PRESENTATION: The 55-year-old male patient presented with right upper quadrant abdominal pain. After radiological imaging studies, the diagnose was of hydatid cyst involving the left lateral segment of the liver ruptured into the gastric lumen and resulted in a cystogastric fistula. Gastroscopy revealed that the cyst and its contents protruding from anterior wall to the gastric lumen. Partial pericystectomy and omentopexy were performed and the gastric wall was primarily repaired. There were no complications in the postoperative period and 3-month follow up. CONCLUSION: This case, to our knowledge, is the first reported case of cystogastric fistula surgically treated in a patient with liver hydatid cyst in the literature. Our clinical experience shows that, although it is a benign disease, complicated hydatid cysts should be evaluated in detail preoperatively, and after the detailed diagnostic work-up, surgical therapy might be planned individually for each case.

Alveolar echinococcosis is a rare but severe parasitic disease and is now in Europe the parasitic infection associated with the most morbidity and mortality. Its prevalence is increasing in Switzerland in both urban and rural areas. Echinococcosis is a differential diagnosis that should be considered when facing a cystic hepatic lesion. Moreover, this parasitic infection is increasing amongst immunocompromised patients, making the diagnosis more complex, because of atypic lesions and a more rapid evolution. At the current time, several treatment options, both surgical and medical, can offer patients a good prognosis and maintain a good quality of life.
L'échinococcose alvéolaire est une parasitose rare mais sévère. En Europe, il s'agit de l'infection parasitaire causant le plus de morbimortalité. Son incidence est en augmentation en Suisse dans les zones urbaines et rurales. L'échinococcose est donc un diagnostic différentiel à évoquer face à une lésion kystique hépatique. En outre, cette infection parasitaire est en augmentation chez les patients immunosupprimés, chez qui le diagnostic est plus complexe en raison de lésions atypiques et d'une évolution plus rapide. À l'heure actuelle, plusieurs modalités de traitements chirurgicaux et médicamenteux permettent d'offrir un bon pronostic aux patients tout en maintenant une bonne qualité de vie.

BACKGROUND: Alveolar echinococcosis (AE) is an endemic parasitic zoonosis in Germany. In most cases, the liver is the primary organ affected. CASE PRESENTATION: A 59-year old female patient presented with increasing exertional dyspnea and unintentional weight loss. A computed tomography (CT) scan showed a left-sided chylous pleural effusion and multiple intrahepatic masses with infiltration of the diaphragm and the pleura. The findings were initially misinterpreted as hepatocellular carcinoma (HCC) with infiltrating growth. Liver biopsy of one of the masses showed no evidence of malignancy, but an amorphous necrosis of unclear origin. HCC was further ruled out by magnetic resonance imaging (MRI). However, MRI findings were highly suspicious for hepatothoracic dissemination and complications due to AE. Typical histologic findings in a repeated and more specific examination of the liver tissue and a positive serology for echinococcosis confirmed the diagnosis of AE. As the hepatic and pulmonary manifestations were considered inoperable in a curative matter, an anti-parasitic treatment with albendazole was initiated. A video-assisted thoracoscopic surgery (VATS) with removal of the chylous effusion as well as a talc pleurodesis was performed to relieve the patient from dyspnea. Two months later, the patient was asymptomatic and a positron emission tomography (PET)-CT-scan with [18 F] fluoro-2-deoxy-d-glucose (FDG) showed a remarkable diminution of the hepatic manifestation. CONCLUSIONS: This case demonstrates a rare presentation of alveolar echinococcosis with a focus on pulmonary symptoms, emphasizing the importance of evaluation for pulmonary involvement in patients with AE and respiratory symptoms.

Hydatidosis (Echinococcosis) is a disease caused by infestation of hydatid cysts in any organ of body but mainly liver (70% of cases). Hydatidosis of salivary glands is rare and necessitate computerized tomography for diagnosis while fine needle aspiration remains controversial procedure. MATERIALS AND METHODS: 6 patients diagnosed with hydatid cysts of parotid glands. These cases were admitted and treated at the maxillofacial surgery Clinic of the "AL-Ramadi" Hospital in Iraq. 5 patients were female and 1 male with age group was between 30 -50 years. The patients complained of painless unilateral swelling in parotid region and who were diagnosed hydatid cysts using CT. All cases were treated by superficial parotidectomy with cystectomy and preservation of facial nerve. RESULTS: All hydatid cysts are CE1- type with no recurrences were reported in any of these cases. The postoperative edema was the most common complication. Other complications were not seen. CONCLUSION: parotid hydatid cyst should be included in differential diagnosis of persistent parotid swelling especially those with history of hepatic hydatid cysts. Computerized tomography is the gold imaging that aid in diagnosis and classification of hydatid cysts. Most cases are CE1 type and Eosinophilia is a sign of concern in some patients. Surgical treatment remains the "gold standard" in therapy.
