[Application of plasma prostate electrovaporization system in the treatment of rectal cicatricial stenosis].

Objective: To evaluate the feasibility, maneuver and efficacy of plasma prostate electrovaporization system in the treatment of rectal cicatricial stenosis.

Methods: According to similar procedure of transurethral resection prostate(TURP), intrarectal cicatriclectomy was performed with plasma prostate electrovaporization system in 7 patients with rectal low cicatricial stenosis after rectal cancer treatment (5 patients with transabdominal low anterior resection,2 patients with 3-dimension precise radiotherapy) to remove obstruction and dilate enteric cavity.

Results: Seven patients underwent 12 operations, including one operation in 3 patients, two operations in 3 patients, 3 operations in one patient. Resected rectal cicatricial tissue ranged from 5 to 15 g. Mean operation time was 41 min (25 to 40). Operation successful rate was 100% without complications such as perforation, bleeding and infection. All the patients had smooth defecation.

Conclusion: Plasma prostate electrovaporization system is an effective treatment for rectal cicatricial stenosis with tiny trauma.
