Objective To understand the tegumentary tissues around the anastomats after the Lobectomy surgeries by thoracoscope and to differentiate with recurrences and metastases of lung cancers. Methods A total of 43 patients who accepted Lobectomy surgeries in our hospital from October, 2016 to October,2017 were chosen, and accepted CT scans within one month after Lobectomy surgeries. Observe if there were tegumentary tissues appearing around the anastomats. The patients with tegumentary tissues accepted CT scans in the 3rd month and the 6th month respectively after the Lobectomy surgeries. Observe the sizes, forms, positions of the tegumentary tissues, and the absorption of them. Results There were 14 cases appearing tegumentary tissues, and the percentage was 32.6%.The anastomats were in the tegumentary tissues in 10 cases, and at the edge of tegumentary tissues in 4 cases. The tegumentary tissues in the whole 14 cases were absorbed in different degrees. Among them, 9 cases were absorbed completely, and five cases were absorbed partially. Conclusion To understand the occurrence rate of tegumentary tissues after the Lobectomy surgeries by thoracoscope, the features of them, and to observe the absorption situation, was helpful to differentiate with recurrences and metastases of lung cancers.
