目的 :探讨研究一种新的气管成形吻合术在气管肿瘤外科的应用价值。方法 :对 1例肿瘤的长度 5 8cm的气管中段鳞癌的病例采用右胸后外切口 ,在切断右下肺韧带、环形切开右肺门整圈心包返折、充分游离隆突及左、右总支气管的基础上 ,设计在上下气管斜形断端的一侧行小范围间断缝合 ,使之气管长度适当加长、在此基础上再施行“Z”字成形吻合术。结果 :气管巨大癌肿切除后气管断端直接成形吻合获得一期愈合 ,随访一年 ,情况良好。结论 :对肿瘤巨大的气管癌肿可根据病灶的具体情况 ,灵活设计斜行袖式切除和包括“Z”字成形吻合等多种形式的成形吻合术 ,可取得满意的临床效果 ,并具有推广价值 Objective: To investigate the application of a new tracheal anastomosis in tracheal tumor surgery. Methods: One case of squamous cell carcinoma of the middle trachea with a length of 58cm was treated with right extrathoracotomy, the right lower pulmonary ligament was cut off, On the basis of the right total bronchus, a series of intermittent sutures are designed on the side of the oblique ends of the upper and lower trachea so as to make the length of the trachea longer. On the basis of this, a “Z” shaped anastomosis is performed. Results: The first tracheal anastomosis was achieved by direct anastomosis of the trachea after resection of giant tracheal carcinoma. One year follow-up was in good condition. Conclusion: The huge tracheal cancer of the tumor can be designed according to the specific circumstances of the lesion, and the flexible design of oblique sleeve sleeve resection and the formation of “Z” shaped anastomosis and other forms of anastomosis can achieve satisfactory clinical results, and has the promotion value
