Disposable biopsy forceps have recently been introduced into the field of endoscopy. We have analyzed biopsy size and histologic interpretation of samples obtained with the disposable forceps and compared them to those obtained with reusable forceps. In the 18 patients studied, 49 samples were collected with the reusable forceps and 47 samples with the disposable. Biopsy sites included the colorectum in 50%, esophagus in 22%, small bowel in 17%, and stomach in 11% of the patients. We found that statistically smaller samples were collected by the disposable biopsy forceps than by the reusable (2.48 +/- 1.11 mm versus 1.99 +/- 0.55 mm, p = 0.006). The smaller biopsy size with disposable forceps was not clinically important since all but one of 47 specimens were interpreted as adequate for histologic diagnosis. The convenience, potential cost savings, and prevention of the spread of communicable agents afforded by disposable biopsy forceps make them a possible alternative to conventional forceps in some clinical settings.
一次性活检钳最近已被引入内窥镜领域。我们分析了使用一次性活检钳获取的样本的活检大小和组织学解读，并将其与使用可重复使用活检钳获取的样本进行了比较。在研究的18例患者中，使用可重复使用活检钳收集了49个样本，使用一次性活检钳收集了47个样本。活检部位包括50%的患者的结直肠、22%的食管、17%的小肠和11%的胃。我们发现，一次性活检钳收集的样本在统计学上比可重复使用活检钳收集的样本小（2.48±1.11毫米对1.99±0.55毫米，p = 0.006）。一次性活检钳获取的活检样本较小在临床上并不重要，因为47个标本中除一个外均被认为足以进行组织学诊断。一次性活检钳所提供的便利性、潜在的成本节约以及对传染病传播的预防，使其在某些临床环境中成为传统活检钳的一种可能替代方案。
