INTRODUCTION: Hydatid cyst (HC) of lung is a frequently encountered entity in Pakistan. The clinical and radiological manifestations of HC in lung depend on the integrity of the cyst. Patients may remain asymptomatic for years in cases of simple HC or may present with a wide variety of complications when it ruptures. The aim of this study was to compare management outcomes in simple and complex HCs. METHODS: This prospective, observational study was conducted from February 2019 until May 2020. Patients were divided into two groups: simple HC (Group A) and complex HC (Group B). Preoperative complications, surgical procedures, postoperative complications, duration of hospital stay, duration of chest tube placement and need for readmission were noted and compared between the two groups. All data was processed through the Statistical Package for the Social Sciences (SPSS) Statistics version 22 (IBM Corp., Armonk, NY). RESULTS: Sixty-two patients were included out of which Group A had 28 (45.2%) patients and Group B had 34 (54.8%) patients. There were 39 (62.9%) males and 23 (37.1%) females. The mean age was 31.11 ± 11.02 years. Preoperative complications in Group B included empyema seen in 10 (28.5%) patients, rupture of cyst into bronchus in 8 (23.5%), biliopleural fistula in 4 (11.7%), hydropneumothorax in 2 (5.8%), bronchopleural fistula in 1 (2.9%), airway compromise in 1 (2.9%) and pneumonia in 1 (2.9%) patient. Group B required longer days of chest tube placement, longer intensive care unit stay and longer hospital stay (p<0.001). The frequency of postoperative intervention was more in group B (p<0.05), therefore requiring readmission. CONCLUSION: Surgery has favorable outcomes in the management of HC of lung. Complications associated with complex HC not only requires preoperative intervention like chest tubes but can also lead to life-threatening complications. There is also a frequent need for additional procedures during surgery in cases with complex HC along with greater risk of postoperative complications. All these are associated with prolonged hospital stay, readmissions and greater morbidity. Hence, early diagnosis and referral is needed to avoid these preventable complications associated with cyst rupture.
