Sleeve Lobectomy: To Wrap or Not to Wrap the Bronchial Anastomosis?

Bronchoplastic procedures have become the reference standard in the lung parenchyma-sparing treatment of centrally located bronchopulmonary tumors. Two schools of thought exist regarding performing a bronchial sleeve resection: those who wrap the anastomosis with a pedicled flap and those who leave the anastomosis unprotected. We performed a study comparing these 2 methods.

This study was a retrospective multicenter observational analysis of 90 consecutive patients undergoing bronchial sleeve resections for neoplastic disease between June 2009 and July 2019. Group A (60 patients) underwent bronchial wrapping and group B (30 patients) did not undergo wrapping.

The only difference between group A, which had 5 patients (8.3%), and group B, which had 10 patients (33.3%), regarding general characteristics was the presence of diabetes (P = .003). There were no differences in surgical, postoperative, and follow-up characteristics. There was no statistically significant difference between groups (group A, 9 patients [15%]; and group B, 6 patients [20%]) in terms of anastomotic complications at 1 year (P = .425). Diabetes was an independent predictive factor for anastomotic complications at 1 year (P = .035). The number of postoperative complications (P < .001) was an independent risk factor for length of hospital stay.

We found no differences between groups in terms of postoperative complications and length of hospital stay, which confirmed previous reports that sleeve resections may be performed safely without bronchial wrapping.
