Clip closure is effective for large (≥ 20 mm) nonpedunculated polyps in the proximal colon. The cost-effectiveness analysis by Albeniz et al. found that selective clipping of polyps at a minimum risk (>13% in the United States, >10% in Spain) is worthwhile clipping. Although such model is theoretically sound, clinical practice should be primarily guided by efficacy data. Moreover, the analysis is very sensitive to the high price of clips, which is likely to reduce in the foreseeable future.
夹闭对于近端结肠中较大（≥ 20mm）无蒂息肉是有效的。Albeniz 等人的成本效益分析发现，对最小风险（美国＞13%，西班牙＞10%）的息肉进行选择性夹闭是值得的。尽管这种模型在理论上是合理的，但临床实践应主要以疗效数据为指导。此外，该分析对夹闭器的高昂价格非常敏感，而夹闭器的价格很可能在可预见的未来降低。
