Bipolar Plasma Kinetic Vaporization Resection in the Management of Benign Anastomotic Stricture after Rectal Cancer Surgery: A Report of 12 Cases

Abstract Background: Postoperative anastomotic stricture is a common complication after kinds of rectal cancer surgery, especially in low anterior resection and anal retention patients. Currently, various of treatments including anal expansion, endoscopic dilation and also surgery are applied with different efficacy and safety. Besides, bipolar plasma kinetic vaporization resection is a technique used to be applied for benign prostatic hyperplasia with minimally invasion and high safety. To the best of my knowledge, it had not been reported to be applied for narrow scars after rectal surgery.Methods: To analysis retrospectively the clinical data of 12 patients who suffered anastomotic strictures after rectal cancer surgery in the First Hospital of Jilin University from Feb 2015 to December 2017. Result：All of them were successfully treated by the technique of once bipolar plasma kinetic vaporization resection in 8 cases, twice in 3 cases, and more times in 1 cases without occurrence of additional complications. Conclusions: Demonstrated by these limited cases, bipolar plasma kinetic vaporization resection would be applied as an alternative method in the treatment of postoperative anastomotic strictures due to its advantages as well as its effectiveness and safety.
