Giant Hydatid Cyst with Diaphragmatic, Pericardial, and Hepatic Involvement: Use of Extracorporeal Circulation for Major Liver Resection: A Case Report and Literature Review

Hepato-thoracic cystic echinococcosis transit. Clinical features, postoperative complications and hospital mortality. A systematic review

BACKGROUND

Hepato-thoracic hydatid transit (HTT) is an evolutionary complication of hepatic cystic echinococcosis. This study aimed to report the available evidence regarding postoperative complications (POC) and hospital mortality (HM).

METHODS

Systematic review. Studies related to HTT were included. Searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS.

PRIMARY OUTCOMES

POC and HM.

SECONDARY OUTCOMES

publication date, origin and designs, number of patients, cyst type, hospital stance, treatments; and methodological quality (MQ) of studies applying MInCir-T and MInCir-Pr2 scales. Descriptive statistics, weighted means (WM) and their comparison using least squares logistic regression, and meta-analysis of prevalence of POC and HM were applied.

RESULTS

604 studies were retrieved (101 met selection criteria, representing 1020 patients). WM age: 42.6 years, 58.3 % male. Reports are mainly from Spain (19.8 %) and Turkey (17.8 %). With a WM of 18.3 days of hospital stance, it was verified 28.9 % of POC, 12.6 % needed re-interventions, and 9.7 % died. MQ of studies: 9.1 ± 1.9 (MInCir-T) and 13.2 ± 2.9 (MInCir-Pr2). Comparing the behavior of variables in two periods (1983-2002 vs. 2003-2024), statistically significant differences were observed in POC, HM, and reinterventions.

CONCLUSION

HTT is associated with high POC, and significant HM, despite the passage of time.

Pericardial hydatid cyst: A comprehensive case report on diagnosis and multidisciplinary intervention in a young patient

Pericardial hydatid cysts, although rare, present unique diagnostic challenges and require a multidisciplinary approach for effective management. This parasitic infection, caused by Echinococcus granulosus larvae, typically affects the liver and lungs but can manifest in the pericardium, leading to potentially life-threatening complications if untreated. The 22-year-old female's escalating dyspnea posed diagnostic challenges despite inconclusive echocardiography. Employing a multidisciplinary strategy, including preoperative albendazole therapy and surgical excision, effectively managed the condition. This case highlights the intricate diagnostic nature of pericardial hydatid cysts, emphasizing the importance of heightened clinical awareness, especially in endemic regions. The detailed clinical trajectory, imaging methodologies, and therapeutic interventions contribute significant insights to the medical community. The study aims to deepen comprehension and guide clinicians in refined diagnostic and treatment approaches for pericardial hydatid cysts, ultimately improving patient outcomes. It underscores the imperative for continued research in this niche to enhance medical understanding and optimize clinical practices.

A Very Rare Cause of Dyspnea in a Child: A Hydatid Cyst From Echinococcus

Hydatid cyst is a human parasitic disease caused by echinococcus granulosus that affects mainly the liver or the lungs but may be found in any organ, including the heart in up to 2% of the cases. Humans are infected as accidental hosts by contaminated vegetables or water and by contact with saliva from infected animals. Although cardiac echinococcosis can be fatal, it is rare and often asymptomatic in the early stage. We present the case of a young boy living on a farm who suffered from mild exertional dyspnea. He suffered from pulmonary and cardiac echinococcosis and was treated surgically through median sternotomy to prevent potential cystic rupture.

Zoonotic Transmission of Hepatic Hydatid Cyst from Domestic Dogs: A Case Report from an Urban-Marginal Area in Ecuador

BACKGROUND Hepatic hydatidosis, or echinococcosis, is a zoonosis with worldwide prevalence and is potentially lethal in humans. This report presents a case of hydatidosis in a 40-year-old woman that was associated with a zoonotic transmission of Echinococcus granulosus from domestic dogs in an urban-marginal area of the city of Guayaquil, Ecuador. This report shows how early diagnosis and awareness favored the correct treatment of the disease. CASE REPORT A 40-year-old woman from the aforementioned sector presented the following symptoms: malaise, pain in the upper right hypochondrium, palpable mass, jaundice, and fever. Next, the patient's fecal samples were analyzed by direct coproparasitic methods, flotation, and sedimentation with centrifugation using saline solution, whereby the presence of Entamoeba histolytica eggs was determined. Likewise, she underwent an ultrasound, in which hepatic hydatid cysts were observed. Subsequently, the cysts were treated and surgically removed, and parasitic forms of E. granulosus were identified. Later, coproparasitic analysis of her 2 domestic dogs for coproantigen ELISA were performed, by which the presence of this cestode was also identified and confirmed. CONCLUSIONS Hydatidosis is a zoonosis that can affect the population, especially in endemic areas of developed and underdeveloped countries. In this case, hepatic hydatidosis was identified in a 40-year-old woman. Additionally, the presence of E. granulosus eggs was determined in the fecal matter of her dogs, which indicated that the patient's relatives and other people around them were exposed to this zoonosis.
