Capitonnage method selection in pulmonary hydatidosis with purse-string or interrupted suture

Disfigurements in the lung parenchyma due to capitonnage methods may lead to long-term atelectasis. The aim of the present study was to examine whether there are any complication differences between the capitonnage applied via interrupted suture or purse-string suture.

Of the total of 120 cases that underwent hydatid cyst surgery during 2007 and 2020, those that were subject to capitonnage were included in the study. The preoperative and postoperative findings were analyzed for 76 cases subject to purse-string capitonnage (Group I) and 24 interrupted capitonnage (Group II).

While the number of cases with complication in Group I was 16 (21.1%), there were only 2 (8.3%) complications in Group II; however, the difference was not statistically significant (P = 0.23). Bronchopleural fistula (n = 1) and prolonged air leak (n = 2) were observed in Group I, there was no bronchopleural fistula or prolonged air leak in Group II. Atelectasis was the most frequently observed complication observed in 12 (15.8%) cases in Group I and 2 (8.3%) cases in Group II (P = 0.53). The duration of hospitalization was lower for the patients in Group II. The number of days was 7.3 ± 2.7 for Group I and 5.3 ± 2.1 for Group II (P < 0.01).

This study is the first to compare whether there are any complication differences between the capitonnage methods via interrupted suture or purse-string suture. The results of the study put forth that the duration of hospitalization is lower in the interrupted capitonnage group. Parenchymal anatomy may be preserved better in interrupted capitonnage method.
