Abstract: Objective To investigate the clinical efficacy of endoscopic resection of small colorectal polyps with thermal biopsy forceps. Methods A total of 390 patients with colorectal polyps treated during Jan. 2015 and May 2017 were selected, with 929 micro-polyps(diameter 1-10 mm)involved. The patients were divided into 2 groups according to different methods of polypectomy: thermal biopsy forceps group(n=183, 562 polyps), and argon plasma coagulation group(n=137, 367 polyps). The clinical efficacy of the 2 groups were compared. Results In the thermal biopsy forceps group, the removal rate of polyps ≤6 mm was 100%, and the effective rate for polyps <10 mm was 97.5%. In contrast, in the argon plasma coagulation group, the effective rate for polyps <10 mm was 86.6%. No perforation developed in either group. In the thermal biopsy forceps group, bleeding occurred in 1 case and slight abdominal pain in 2 cases. The incidence of postoperative complications was 1.6%. In the argon plasma coagulation group, bleeding occurred in 3 cases and abdominal pain in 5 cases. The incidence of postoperative complications was 5.8%. Conclusion Compared with traditional argon plasma coagulation, endoscopic thermal biopsy forceps is simple and effective for the resection of colorectal polyps ≤6 mm. It is worthy of wide clinical application.
