Objective To evaluate the efficacy and safety of high-frequency electric dissection for colorectal cysts.Methods The personal information,clinical data,operation methods and postoperative complications of patients who were diagnosed as having colorectal cysts and underwent high-frequency electric dissection in Nanfang hospital and Zhujiang Hospital of Southern Medical University between January 1st,2005 and July 1st,2015 were analysed.All patients enrolled in the study were followed up to obtain their resuits of colonoscopy.Results A total of 63 patients were enrolled into our study,9 lesions located in the ileocecus,17 in the ascending colon,19 in the transverse colon,10 in the descending colon,7 in the sigmoid colon and 1 in the rectum.The maximum diameter of the cysts was 20.2+7.5 mm (5-40 mm).All patients underwent high-frequency electric dissection to remove the cysts completely or part of the cyst wall for drainage.Hemorrhage occurred in only one patient and bleeding stopped after being clipped by Titanium clip.Forty-five patients were followed up and there were no delayed complications or recurrence during a postoperative follow-up of 24.1 + 14.3 months (6-87 months).Conclusion High-frequency electric dissection is a safe and effective procedure for the treatment of colorectal cysts.
