Comparison study colonic polypectomy / Монголын Анагаах Ухаан

ABSTRACT

Introduction@#Colorectal cancer remains one of the critical healthcare challenges nowadays. There are a lot of studies done on colonic polypectomy around the world, and mostly diagnosis with dysplasia change, so we consider to chose to study this topic.@*Aim@#In this study, we aimed to compare the between cold snare polypectomy (CSP) and hot snare polypectomy (HSP) of removing colon polyps. This method helped us to investigate which of the two methods is most prevalent for polypectomy.@*Materials and Method@#The research was carried out using a targeted sampling method from the cases where colonoscopy was performed between 2022 and 2023, based on the Center for Imaging Diagnostics and Pathology of Third General Hospital of Mongolia with a colon polyps less than 5mm in size should be removed using the cold snare method according to the recommendation, and polyps between 5-10 mm should be removed using the hot snare method. After polypectomy, we assessed deep mucosal lesions using the Sydney classification.@*Result@#The average age of the 81 cases included in the study was 57.9 years, and the male-female ratio was 1:1.2.149 cases (75.6%) of slightly elevated type 0-IIa according to the Paris classification, according to the morphological structure revealed by endoscopy, while 79 cases (75.6%) were tubular adenoma according to histological analysis. (38.9%), low grade dysplasia 52 (25.6%) and high grade dysplasia 3 (1.5%) cases are noteworthy. Average polyp was 5-9 mm. Most of polyps removed was left side of colon especially in sigmoid colon. Bleeding rate was higher in hot snare method 11.5%. (1/149, 0.7%, 5/52, 9.6%; P = 0.6). There was no recurrent rate and no perforation in our study. @*Conclusions@#In our study, average size of 5-9 mm were removed and slightly elevated (0-IIa), sessile (0-Is) type of polyps were commonly found in the sigmoid colon. There is a higher risk of bleeding due to mucosal damage in hot snare polypectomy. A combination of hot and cold methods is equally effective for resection of colon pollyps up to 1 cm in size.
