Clinical evaluation of endoscopic submucosal dissection with improved snare for colorectal polyps and submucosal tumors
摘要
Abstract
Objective To evaluate the therapeutic effectiveness and safety of endoscopic submucosal dissection (ESD) with improved snare for colorectal polyps and submucosal tumors.Methods The clinical data such as clinical pathological characteristics, en bloc resection rate, curative resection rate, complications and follow-up results of 20 patients with colorectal polyps or submucosal tumors, who were treated by ESD, were retrospectively analyzed.Results 20 patients (total 24 lesions) with colorectal polyps or submucosal tumors were performed ESD operation successfully, in which 16 cases (total 20 lesions) were treated by ESD with improved snare (the trial group), 4 cases were treated by ESD with HOOK knife (the control group).The surgical success rate was 100.0% (24/24), the en blot resection rate was 100.0% (24/24). The mean polyps diameter in the trial group was (2.4 ± 0.9) cm (1.2~4.0 cm), while that in the control group was (2.2 ± 0.6) cm (1.5~3.0 cm). The mean procedure time in the trial group was (83.3 ± 23.9) min (45.0~120.0 min), while the control group was (66.2 ± 15.4) min (45.0~80.0 min), compared with the control group, the trial group need more times to complete the operation. The postoperative pathology as follows: 15 cases were adenoma (including 3 cases of adenoma with partial gland high-grade intraepithelial neoplasia), 1 case was hyperplastic polyp, 1 case was high-grade intraepithelial neoplasia, 2 cases were neuroendocrine tumor (total 4 lesions) 1 case was stromal tumor. Except for 1 case of stromal tumor from the muscularis propria was taken full thickness resection, no patient appeared complications such as hemorrhage, perforation, infection. No patient need intraoperative and postoperative surgical treatment.Conclusion Improved snare can be used to endoscopic submucosal dissection for large colorectal polyps and submucosal tumors safely and effectively, expanded the use and indications of snare in endoscopic resection, but need more times to completed the operation.关键词
