    Background
    

    The present study describes and compares the rate of complications in hospital length of stay (LOS), recurrences and long-term survival between pneumonectomies and bronchial sleeves in our center's experience.

    This is a descriptive, retrospective study. All patients who underwent bronchial SL or PN for NSCLC in our center between 2011 and 2017 were included. Individual clinical report was done, other indications for surgery were excluded. General demographics, preoperative lung function, histology and postoperative complications were included. Oncologic follow-up was done to detect recurrence and death. The statistical program used was SPSS.

    From of 87 patients registered, 47 had bronchial sleeve resection (54,02%) and 40 pneumonectomy (45.97%). The average age: SL 63.7, PN 61,7 years. Males were predominate in both groups (SL 83%, PN 75%). The average size tumoral were: SL 4,8 cm, PN 7,5 cm, p=0.46). Histological type predominant was C. squamous: SL 57,44%, PN 60%, p=0,46). The average LOS was higher SL than PN (2,37 and 6,37 respectively). Upper SL were most frequent: LSD 23 cases, LSI 17 cases, left pneumonectomies were the most accomplished.

    25 patients had postoperative complications: SL 17 (68%), PN 8 (32%). The most frequent complications were persistent air leak (SL 6 cases, PN 0 cases, p=0.09) and cardiac arrhythmias. (SL 3 cases, PN 4 cases p=0.09)

    No case of local recurrence was found after both techniques and 8 cases of regional recurrences (SL 6, PN 2, p=0,81).

    No differences in terms of overall survival were detected when both techniques were compared (median survival in months, p=0.35).

    More postoperative complications were found in SL group with equal postoperative mortality, this is mostly because persistent air leak and bronchial stenosis, this could explain increase of LOS.

    There are no local recurrences in any groups, this could mean that both techniques are oncologically equivalent. Our definition of regional recurrences as tumor involving the ipsilateral lung might again explain the higher incidence in SL.

    There are no statistically differences in terms of OS in both techniques. However, long-term survival tendency appears to be in favor of SL specially after 5 years. This might be related to non oncologic late complications related to pneumonectomy.

    In conclusion, we consider SL as a feasible and secure technique with a reasonable incidence of inherent complications and equal oncological results.
