Parenchyma Sparing Procedures Is Possible For most Pulmonary Hydatid Disease Without Recurrence and Low Complications

Objective: A retrospective review of 223 patients (242 operations) of pulmonaryhydatid cysts. We analyze and evaluate our experience in the surgical managementof this Moroccan endemic disease and concluded that parenchymasavingmust be always used. Materials and methods: In an 8 year period (2002-2009), 223 patients (242 interventions, 282 pulmonary hydatid cysts) were operatedon in our department. There were 166 males and 57 females with a mean age of 45.7years. The diagnosis was established on the basis of different clinical signs and imagingstudies. Surgical approach consisted of a posterolateral thoracotomy in all cases.Different surgical procedures were performed on the pulmonary lesions accordingto the localization, the size, the complicated or intact cyst and the importance oflung destruction. Results: Parenchyma-saving were done in 217 patients (238 interventions)cases, including cystectomies (189 cysts), pericystectomies (47cysts)with capitonnage of the cavity in 177 cysts. Radical treatment as lobectomies is usedin only 6 cases. Postoperative minors complications occurred in 13 cases (5.4%),including 6 prolonged air leak, 4 pneumonias, one wound infection and two transitoryresidual cavities. There was no postoperative death. All patients were free ofrecurrence of thoracic hydatid disease in a follow-up ranging from 3 to 90 months(mean: 49 months). Conclusion: Hydatid cysts of the lung should be treated beforecomplications. Parenchyma saving is the best procedures for this benign disease;the radical resection must be reserved only for pulmonary destruction.
