Background and Objectives Recently, the use of the potassium‐titanyl‐phosphate (KTP) laser with a wavelength of 532 nm, which is half the wavelength of the neodymium:yttrium‐aluminum‐garnet (Nd:YAG) laser, has been expanding in many fields, since this laser offers hemostasis and vaporization with minimal coagulation of the underlying structures. The purpose of this study was to determine the usefulness of the KTP laser in limited lung resection done for pulmonary nodular lesions. Study Design/Patients and Methods We used the KTP laser to manage 10 partial resections (Group 1) and 16 segmentectomies (Group 2). The variables that were used to compare the two methods of resection included intra‐operative blood loss, mean drainage time, and post‐operative morbidity. Results The mean intra‐operative blood loss was smaller in Group 1 (152.8 ± 65.0 cc, P = 0.002) than in Group 2 (341.9 ± 178.6 cc). Mean drainage time was shorter in Group 1 (1.8 ± 1.0 days, P = 0.0141) than in Group 2 (3.6 ± 2.9 days). The results of both groups with respect to hemostatic and healing effects were satisfactory. On histopathologic evaluation, the KTP laser‐irradiated field tissue alteration consisted of two layers with a depth up to 2 mm. Conclusions The results of this study suggest that the KTP laser has the potential to become a useful and reliable tool for limited lung resection. Lasers Surg.
