Abstract:
Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) in the treatment of rectal laterally spreading tumors (LSTs) .Methods:The clinical data of 20 patients with LSTs ,who were admitted in Jiangyin Tradi‐tional Chinese Medicine Hospital from September 2012 to September 2014 ,were retrospectively analyzed .According to the su‐perficial morphology of rectal mucosa ,the subtypes of LSTs were determined by endoscopy .Tumor size and morphological characteristics ,pathological features and operation time of ESD were counted .Furthermore ,postoperative complications and recurrence were followed up and statistically analyzed .Results:There were 8 (40% ) cases of LST granular type and 12 (60% ) cases of LST nongranular type .There were 18 cases of adenomas associated with low grade neoplasia and 2 (10% ) cases of high grade intraepithelial neoplasia .There were 7 cases of tubulovillous adenoma and 13 cases of tubular adenoma .The mean diameter of lesions was (33 .9 ± 11 .5) mm .The enbloc resection rate was 100% and the average time of ESD operations was (40 ± 15) min .The postoperative bleeding rate was 10% (2/20) and no perforation occurred .The mean follow‐up period was 12 .6 months ,during which no recurrence was found .Conclusions:With high enbloc resection rate and low complication rate ,ESD is a safe and efficacious treatment for rectal LSTs ,especially for the lesions larger than 2 cm which have higher potential of malignancy .
