Aim of the Study: To develop and introduce into clinical practice a method of staged treatment of villous tumors of the colon based on using the combination of diathermocoagulation and high-intensity laser radiation.

Materials and Methods: The patients were divided into 2 groups. The first (control) group included 80 patients and were treated only with using of endoscopic loop and electricity energy. The second (examined) group consisted of 52 patients. Their treatment included combination of two methods: endoscopic excision with an endoscopic loop and laser vaporization of the tumor base. The patients of both control and examined groups had villous tumors with size from 1.5 to 8 - 9 cm in diameter. In some cases, the base of the tumor occupied up to half of the intestinal lumen, the length reached 8 - 9 cm. Depending on the size of the tumor removal was performed in one stage or in several steps (multistage). In 32 cases tumors excision were performed by its fragmentation during one procedure, in 20 cases the tumors were removed in several stages.

Results. In the control group of patients, tumors up to 2 - 3 cm in diameter in most cases were removed during one procedure. The lesions larger than 3 cm were removed during one or more procedures at the first hospitalization. The relapse rate in this group was 30%. Laser vaporization was used in patients of the examined group. The method was used to vaporize the base of the tumor after endoscopic electroresection of its exophytic part. Relapse of the disease in the second group was observed in 5% of patients.

Conclusion: The use of diathermocoagulation (loop excision of the tumor) and high-intensity laser radiation of various wavelengths can reduce the relapse rate of the disease from 30 to 5%, making this intervention the operation of choice in the treatment of large villous adenomas of the colon.
