Bipolar probe coagulation (BICAP) was evaluated and compared with conventional cold biopsy (CBx) as a potential therapeutic modality for eradication of diminutive colonic polyps (DPs). Seventy-seven and 79 DPs were treated with BICAP and CBx, respectively. Twenty-one percent of the BICAP and 29% of the CBx (p greater than 0.05) group had residual polypoid tissue detected at flexible sigmoidoscopy 3 weeks after treatment. Because of incomplete polyp removal, CBx and BICAP coagulation cannot be recommended as definitive therapies for DPs. Neoplasia was present in 22% of DPs located less than 60 cm from the anus, 73% of proximally located small polyps, and 32% of all DPs. Despite apparent eradication at the time of treatment, the incidence of residual polypoid tissue would suggest the need for critical evaluation of other modalities used to eradicate or remove DPs.
对双极探头凝固术（BICAP）进行了评估，并与传统冷活检（CBx）进行比较，将其作为根除微小结肠息肉（DP）的一种潜在治疗方式。分别用BICAP和CBx治疗了77个和79个DP。治疗3周后，在乙状结肠镜检查中，BICAP组有21%、CBx组有29%（p>0.05）检测到残留息肉样组织。由于息肉切除不完全，CBx和BICAP凝固术不能作为DP的确定性治疗方法推荐。距肛门小于60 cm的DP中22%存在肿瘤形成，近端小息肉中73%存在肿瘤形成，所有DP中32%存在肿瘤形成。尽管在治疗时息肉明显被根除，但残留息肉样组织的发生率表明需要对用于根除或切除DP的其他方式进行严格评估。
