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

Area of Science:

• Thoracic Surgery
• Surgical Techniques
• Pulmonary Medicine

Background:

• Capitonnage methods for lung hydatid cysts can cause lung parenchyma disfigurement and long-term atelectasis.
• Comparing complication differences between interrupted suture and purse-string suture capitonnage is crucial for optimizing surgical outcomes.

Purpose of the Study:

• To investigate and compare complication rates associated with two distinct capitonnage techniques: interrupted suture versus purse-string suture.
• To evaluate the impact of these techniques on postoperative outcomes, including atelectasis, bronchopleural fistula, and hospitalization duration.

Main Methods:

• Retrospective analysis of 100 patients who underwent hydatid cyst surgery with capitonnage between 2007 and 2020.
• Group I: 76 patients (purse-string capitonnage).
• Group II: 24 patients (interrupted capitonnage).
• Comparison of preoperative and postoperative findings, focusing on complication incidence and hospitalization length.

Main Results:

• Lower complication rates (8.3%) were observed in the interrupted capitonnage group (Group II) compared to the purse-string group (Group I) (21.1%), though not statistically significant (P=0.23).
• No bronchopleural fistula or prolonged air leak occurred in Group II, whereas Group I experienced one bronchopleural fistula and two prolonged air leaks.
• Atelectasis was less frequent in Group II (8.3%) than in Group I (15.8%) (P=0.53).
• Hospitalization duration was significantly shorter in Group II (5.3 ± 2.1 days) compared to Group I (7.3 ± 2.7 days) (P < 0.01).

Conclusions:

• Interrupted capitonnage may lead to a shorter hospital stay compared to purse-string capitonnage.
• The interrupted suture technique shows potential for better preservation of lung parenchymal anatomy.
• This study provides initial evidence supporting interrupted capitonnage for improved postoperative recovery in hydatid cyst surgery.
