Colorectal ESD can achieve en-bloc resection. However, cecum, hepatic and splenic flexures are difficult locations because of unstable scope maneuvers and narrow working space. In these cases, balloon overtube-guided ESD may confer a better approach, improving the access to the lesion and scope manoeuvres. This overtube has a large outer diameter and enables the use of a therapeutic gastroscope. The procedure can also facilitate traction-assisted techniques allowing a high-rate of en-bloc resections. In addition, large specimens can be easily retrieved through.
结直肠内镜黏膜下剥离术（ESD）可实现整块切除。然而，由于操作空间不稳定和工作空间狭窄，盲肠、肝曲和脾曲是困难部位。在这些情况下，球囊外套管引导下的ESD可能是一种更好的方法，可改善对病变的观察及内镜操作。这种外套管外径较大，可使用治疗性胃镜。该操作还可促进牵引辅助技术的应用，实现高比例的整块切除。此外，大标本可轻松取出。
