Simultaneous operation for right pulmonary and liver echinococcosis

Area of Science:

• Medical Parasitology
• Thoracic Surgery
• Hepatobiliary Surgery

Background:

• Hydatidosis is a parasitic disease caused by Echinococcus granulosus.
• Pulmonary hydatid cysts are common, but simultaneous liver involvement is less frequent.
• Right lung hydatidosis presents unique diagnostic and surgical considerations due to diaphragmatic proximity.

Purpose of the Study:

• To evaluate the diagnostic methods and surgical outcomes of patients with simultaneous pulmonary and liver hydatid cysts.
• To determine the feasibility of treating concomitant cysts via a single surgical approach.
• To highlight the importance of screening for liver involvement in right lung hydatidosis.

Main Methods:

• Retrospective review of 156 patients referred for pulmonary hydatid cyst between 1977-1987.
• Analysis of diagnostic modalities including radiography, ultrasound, computed tomography, and intraoperative findings.
• Surgical intervention via thoracotomy or thoracolaparotomy for cyst removal.

Main Results:

• Nine patients (5.8%) presented with simultaneous right lung and liver hydatid cysts.
• Diagnostic accuracy was high with imaging techniques (radiography, ultrasound, CT).
• All nine patients underwent successful surgical removal with satisfactory postoperative courses and no recurrence, even without antiparasitic medication.

Conclusions:

• Preoperative screening for subdiaphragmatic liver cysts is crucial in patients with right lung hydatidosis.
• Concomitant liver and lung hydatid cysts can be effectively managed through a single thoracotomy.
• This approach minimizes surgical morbidity and ensures complete parasite eradication.
