Figure 2 Procedures of cap-assisted endoscopic sclerotherapy for internal hemorrhoids and the excision for anal papilla fibroma. A: Internal hemorrhoids with retroflection of the endoscope; B: The anal region under cap-assisted endoscopic view; C: Internal hemorrhoids and anal papilla fibroma under cap-assisted endoscopic view with enough insufflated air; D: The disposable endoscopic long injection needle through operating channel; E: Injection of lauromacrogol into submucosa of internal hemorrhoids with the cap-assisted endoscopic view; F: Injecting of lauromacrogol into submucosa of internal hemorrhoids close to papilla fibroma before dissection; G: Dissection of anal papilla fibroma (confirmed by the followed pathology) after cap-assisted endoscopic sclerotherapy (CAES); H: No bleeding after CAES and dissection of anal papilla lesion before ending all procedures.
