Abstract
From 1986 to 1996, 20 bronchoplastic operations were carried out in patients with lung cancer. In 8 of these, pulmonary arterioplasty (PA-plasty group) was performed, and in other 12 it was not (no PA-plasty group). One patient of PA-plasty group was in p-stage I, 3 in p-stage II, 3 in p-stage IIIA, and 1 in p-stage IIIB. Eight patients of no PA-plasty group were in p-stage I, 1 in p-stage II, and 3 in p-stage IIIA. Bronchoplasty was performed using sleeve resection, and PA-plasty was performed using sleeve resection in 2 patients, and using partial resection in 6 patients. In all cases bronchial and arterial wrapping was not employed. There were no significant differences in intraoperative blood loss or operating time between the two groups. Postoperative complications without troubles of the anastomotic sites occurred in 50 % of the PA-plasty group. But there was no operative or hospital death in either group. The 5-year survival rate of PA-plasty group was 68.5%, and that of no PA-plasty 61.7%. There was no significant difference between the two in the survival rates. Though utmost care must be exercised in the postoperative management of combined bronchoplastic and pulmonary arterioplastic surgery, it is a useful operation to enhance curability as cancer surgery and preserve pulmonary function. It was considered that wrapping for the anastomotic sites was not neccessary.
