Although techniques such as traction methods [<span>2</span>] and tapered hoods [<span>3</span>] have been reported, a standardized strategy has not yet been established. Herein, we report successful underwater ESD (UESD) [<span>4</span>] for a colorectal tumor involving the appendiceal orifice using the continuous irrigation method (CIM) [<span>5</span>], which provides improved visualization and facilitates precise mucosal incision and submucosal dissection by generating water pressure (Video S1). A 47-year-old woman underwent colonoscopy following positive fecal occult blood test results. The procedure revealed a flat, isochromatic lesion measuring 35 mm (type 0-IIa) in the cecum (Figure 1a–c). The lesion was suspected to be a sessile serrated lesion (SSL) and extended into the appendiceal orifice (Figure 1d). ESD was planned using a small-caliber tapered conical hood to improve access to the appendiceal orifice. After lesion marking (Figure 2a), mucosal incision began on the appendiceal side. However, bleeding and bubbles obscured the endoscopic view; therefore, CIM was initiated. CIM rapidly cleared the visual field and utilized water pressure to effectively separate the lesion from the appendiceal orifice, facilitating accurate incision (Figure 2b–d). Circumferential incision and subsequent submucosal dissection were successfully completed under stable visualization provided by CIM (Figure 2e–l). The procedure lasted 91 min.</p><p>The pathological diagnosis was SSL. CIM is a simple approach that improves visualization by clearing air bubbles and bleeding during UESD. Additionally, CIM supports mucosal incision and submucosal dissection through the water pressure effect and facilitates hemostasis via temporary compression, thus enabling safe and efficient en bloc resection of lesions involving the appendiceal orifice.</p><p>Takahiro Muramatsu wrote and edited the manuscript.
