FIGURE 1
Computed tomography reveals a pelvic abscess (A; asterisk) around the rectal carcinoma (B; asterisk). Endoscopic ultrasound-guided pelvic abscess drainage (EUS-PAD) planned to avoid the tumor before the carcinoma operation, and the tumor margin is confirmed (C) with esophagogastroduodenoscopy and the clips placed to avoid puncture of the tumor (D). A pelvic abscess confirmed using EUS (E; asterisk).
FIGURE 2.
Schema of the intra-scope channel plastic stent release in endoscopic ultrasound-guided pelvic abscess drainage (EUS-PAD). The patient presented with a pelvic abscess around a rectal carcinoma (a). EUS-PAD was performed using a convex EUS scope to avoid direct puncture of the tumor (b).
FIGURE 3
Fluoroscopic images show that the double-pigtail plastic stent (DPPS) was bent and released (a; arrow). After insertion of the DPPSs, a large amount of purulent material drains into the colon (b).

The intra-scope channel stent release method is as follows: 1) pull the inner sheath out of the double-pigtail plastic stent (DPPS) (c), leave only the guidewire in the DPPS; (d). 2) pull the guidewire until only a soft tip remains within the DPPS (e); push the straight DPPS into the abscess (f), then change the axis of the DPPS (g); and 3) release the DPPS to bend it (h).
