The sleeve gastrectomy technique is dependent on the size of the bougie and the surgeon's technical skills. Standardization of the sleeve gastrectomy technique may potentially minimize the volume inconsistency and improve outcomes. A volume and pressure-sensitive gastric calibration tube may create a standard sleeve size and minimize interoperator variation. The objective of preliminary testing was to establish the variability of sleeve gastrectomy size in gastric explants, and to compare that with the variability of sleeve gastrectomy size when performed with a volume and pressure-sensitive gastric calibration tube. Three operators performed six sleeve gastrectomies each on commercially processed porcine gastric explants, half with a 40 Fr bougie, and a half with a pressure-sensing and volume-controllable gastric calibration tube prototype. The resulting sleeves were evaluated using standard statistical methods. The pressure-sensitive gastric calibration tube demonstrated superior consistency to a standard 40 Fr bougie by common measures of variation. However, further investigation is warranted to characterize the significance of this difference.
袖状胃切除术技术依赖于探条的大小和外科医生的技术技能。袖状胃切除术技术的标准化可能会最小化体积的不一致性并改善结果。一种容积和压力敏感的胃校准管可以创建标准的袖套大小并最大程度地减少操作人员之间的差异。初步测试的目的是确定胃标本中袖状胃切除术大小的可变性，并将其与使用容积和压力敏感的胃校准管进行袖状胃切除术时的可变性进行比较。三个术者在商业加工的猪胃标本上分别进行了六次袖状胃切除术，一半使用 40Fr 探条，一半使用压力感应和容积可控的胃校准管原型。使用标准统计方法评估所得的袖套。通过常见的变异度测量方法，压力感应胃校准管比标准的 40Fr 探条具有更好的一致性。然而，需要进一步研究来描述这种差异的意义。
