气管造口上缘的肉芽组织和瘢痕是长期带管病人十分常见的问题,传统的方法是用杯状钳或通过造口盲目切除肉芽组织及瘢痕。此法常导致出血,切除不完全。然而激光则能在直视和较少出血的情况下,完全切除肉芽组织和瘢痕。作者应用Sharplan 1100CO_2激光配Wolf支气管镜和激光连接器,0.05秒脉冲15W或连续10～15W功率的激光,对12例患者进行治疗。
Granulation tissue and scarring on the upper edge of the tracheostoma are common problems for long-term patients with canalisation. Traditionally, granulation tissue and scars have been blindly removed using calipers or by ostomy. This method often leads to bleeding, incomplete removal. However, the laser can completely remove granulation tissue and scars with direct vision and less bleeding. The authors used Sharplan 1100CO_2 laser with a Wolf bronchoscope and a laser connector to treat 12 patients with a 0.05-second pulsed 15-watt or continuous 10-15-watt laser.
