JF may be more effective for the removal of DCPs because of their larger size. Aim To evaluate the histological quality and adequacy of DCPs resected using JF compared with HBF. Methods One hundred and seventy-nine patients with 237 DCPs were included in this study. DCPs were removed using either JP or HBF. Results The tissue architecture was good in 29.9 % of the HBF group, in comparison with 90 % of the JF group (p \ 0.001). No cautery damage or crash artifact was observed in 93.3 % of JF group and in 8.5 % of HBF group (p \ 0.001). Moreover, there were statistically significant differences between the groups with regard to the high level of cautery damage or crush artifact (p \ 0.001). The overall diagnostic quality of the specimens removed using JF was significantly better than that of the specimens removed by HBF (96 vs. 80 %, respectively, p \ 0.001). There were statistically significant inverse associations between cautery damage or crush artifact and overall diagnostic quality of HBF and JF (r =-0.373, p \ 0.001; r =-0.382, p \ 0.001, respectively). Surgical margins were determined as negative in 87.5 % of the JF group and in 76.1 % of the HBF group (p = 0.022). A total of 80.8 % of the JF specimens and 30.8 % of the HBF specimens were well evaluated for two lateral and deep surgical margins (p \ 0.001). Conclusion JF was superior to HBF for histopathological interpretation and eradication of DCPs. Keywords Cold forceps polypectomy Á Diminutive colorectal polyp Á Hot biopsy forceps electrocauterization Á Jumbo forceps Introduction Most polyps detected during colonoscopy are 1–5 mm in size (diminutive) [1]. Although the prevalence of cancer in diminutive lesions has been reported to be very low, the majority are adenomatous and have malignant potential, and polypectomy at the time of colonoscopy can reduce the incidence and mortality from colorectal cancers [2, 3].
