What is the most accurate method for the treatment of diminutive colonic polyps?: Standard versus jumbo forceps polypectomy

Abstract

Different methods such as standard, hot, and jumbo forceps are used in endoscopic treatment of diminutive colon polyps. In the current study, it was aimed to compare efficacy and safety of standard and jumbo forceps polypectomy methods in treatment of diminutive colon polyps of ≤5 mm. Polyps with ≤5 mm which were excised during colonoscopy by using standard or jumbo forceps were evaluated. Standard and jumbo forceps polypectomy methods were randomly performed in 212 consecutive patients with diminutive colorectal polyp. One-bite polypectomy and complete resection rates were also determined among polypectomy methods. Results of 161 standard forceps polypectomy and 102 jumbo forceps polypectomy were retrospectively evaluated. Both one-bite polypectomy and complete resection rates were significantly higher in the jumbo forceps polypectomy group than the standard forceps polypectomy group (P < 0.001). In the subgroup analysis performed according to polyp sizes, complete resection rate among polyps with 3-mm diameter was determined as 100%. However, numbers of bites in 4-mm and 5-mm polyps were higher in the standard forceps polypectomy group, and complete resection rate was lower than in the jumbo forceps polypectomy group (P < 0.001). Both endoscopic treatment methods may be employed in treatment of diminutive colon polyps with ≤5 mm. However, jumbo forceps polypectomy is a more effective treatment method in 4- to 5-mm polyps with high one-bite polypectomy and complete resection rate.
