[Bronchial Stump Coverage Technique by da Vinci Xi]

da Vinci's greatest attractions are the fine images acquired with a high-resolution 3-dimensional( 3D) endoscope and the precise operation by forceps equipped with an articulated arm. We believed that complicated procedures can benefit from robot-assisted surgery. We have been actively performing collection and sewing of viable tissue using da Vinci Xi for the purpose of preventing bronchial stump fistulas. Of the 44 cases of lobectomy performed by the end of November 2019 using da Vinci Xi, 13 cases underwent bronchial stump covering. The covering procedure was intended for patients with conditions such as diabetes and a history of internal use of steroids. As the dressing, pedicled intercostal muscle was used in 4 cases, and free pericardial fat tissue was used in 9 cases. A good visual field was obtained by appropriately turning the oblique mirror upside down. The smoke emission effect of AirSeal was useful for securing the visual field. The dressing was sutured and fixed using 3-0 or 4-0 Prolene( SH) cut to a length of 10 to 12 cm. The postoperative course was good and bronchial stump fistula did not occur in all cases.
