Comparison between pulmonary and hepatopulmonary hydatidosis

Area of Science:

• Parasitic diseases
• Thoracic surgery
• Hepatobiliary surgery

Background:

• Hydatidosis is a parasitic infection caused by Echinococcus tapeworms.
• Pulmonary hydatidosis (PH) is common, but co-occurrence with liver cysts (hepatopulmonary hydatidosis, HPH) requires distinct consideration.
• Understanding differences in clinical presentation and surgical management between SPH and HPH is crucial for optimal patient outcomes.

Purpose of the Study:

• To compare clinical features and surgical approaches in patients with single pulmonary hydatidosis (SPH) versus hepatopulmonary hydatidosis (HPH).
• To identify demographic and radiological differences between SPH and HPH.
• To evaluate surgical outcomes and complications in both groups.

Main Methods:

• Retrospective review of 141 patients who underwent surgery for pulmonary hydatidosis between 1991 and 2001.
• Patients were categorized into HPH (n=49) with concomitant liver cysts and SPH (n=92).
• Comparison of clinical, radiological, and surgical data, including postoperative outcomes.

Main Results:

• HPH was more prevalent in females and patients over 40 years old.
• HPH cases showed a higher tendency for multiple and bilateral pulmonary cysts compared to SPH.
• Surgical approaches for concomitant liver cysts included thoracophrenotomy and sternophrenotomy; no significant differences in complications or hospital stay were observed between HPH and SPH groups.

Conclusions:

• Pulmonary hydatidosis patients should be screened for multi-organ involvement, particularly liver cysts.
• HPH, more common in older females, presents with distinct cyst characteristics (bilateral, multiple pulmonary cysts) and may warrant different surgical strategies.
• Considering HPH as a distinct entity is recommended due to potential complexities in management and prolonged recovery.
