Efficacy of endoscopic high-frequency electrocoagulation with a snare device combined with APC in the treatment of flat colorectal polyps sized 0.5-1.0 cm
Objective To explore the effect of high-frequency electrocoagulation with a snare device combined with argon plasma coagulation(APC)in the treatment of flat polyps of the colon and rectum sized 0.5-1.0 cm.Methods A total of 100 patients(163 polyps)with colorectal polyps sized 0.5-1.0 cm were divided into an experimental group(50 cases,83 polyps)and a control group(50 cases,80 polyps)according to different surgical method.The experimental group received endoscopic high-frequency electrocoagulation with a snare device combined with APC treatment,while the control group received endoscopic high-frequency electrocoagulation with a snare device.The one-time resection rate of polyps,complications,and the recurrence rate during the 1-year follow-up of the two groups were compared.Results In the experimental group,80 polyps were excised once with high-frequency electrocoagulation with a snare device combined with APC,and the stumps were further coagulated with argon ions until the surface of the polyps turned white.In the control group,65 polyps were excised once with high-frequency electrocoagulation with a snare device,and the stumps were excised with biopsy forceps or thermal biopsy forceps.The one-time resection rate of polyps in the experimental group was 96.39%,which was higher than 81.25%in the control group,and the difference was statistically significant(P<0.05).In the experimental group,2 patients had a small amount of bleeding due to the deep wound after electrocoagulation resection of broad-based polyps,and the wound was clamped with titanium clips,and there were no complications such as delayed hemorrhage and perforation;3 patients had postoperative abdominal distension and discomfort,which were completely relieved after 1 d of bed rest.In the control group,there were no complications such as bleeding and perforation,and 2 patients had abdominal distension and discomfort after surgery,which was completely relieved after 1 d of bed rest.There was no significant difference in complication rate between the two groups(P>0.05).The recurrence rate within 1 year after surgery in the experimental group was 0,which was lower than 14.00%in the control group,and the difference was statistically significant(P<0.05).Conclusion In the treatment of flat colorectal polyps sized 0.5-1.0 cm,endoscopic high-frequency electrocoagulation with a snare device combined with APC can effectively improve the complete resection rate,without significantly increasing complications,and has a low recurrence rate,which is worthy of clinical promotion and application.
