Polypectomy-associated bleeding is the most frequent complication of colorectal polypectomy.
An 82-year-old woman underwent polypectomy after an endoloop was placed in a pedunculated polyp in the sigmoid colon. However, the endoloop dislodged, causing massive bleeding from the stem surface. Furthermore, the bleeding vessel could not be identified because of the narrow resection surface and the presence of thrombus and hemorrhage. Therefore, several clips were removed, and polypectomy was performed again on the resection stem to open the resection surface wider and identify the bleeding vessels. Finally, the responsible arterial vessel appeared, leading to complete hemostasis.
The additional stem resection may be a novel method for detecting uncontrolled bleeding after polypectomy for colorectal pedunculated polyps.
息肉切除术后出血是结直肠息肉切除术最常见的并发症。
一名82岁女性在乙状结肠带蒂息肉放置圈套器后接受了息肉切除术。然而，圈套器脱落，导致息肉蒂表面大量出血。此外，由于切除表面狭窄以及存在血栓和出血，无法识别出血血管。因此，移除了几个夹子，并再次对切除蒂进行息肉切除术，以更宽地打开切除表面并识别出血血管。最后，责任动脉血管出现，实现了完全止血。
额外的蒂切除可能是一种检测结直肠带蒂息肉息肉切除术后无法控制出血的新方法。
