Our hospital CT scan showed that the appendix was locally thickened and enhanced, chronic fecal appendicitis was suspected, and multiple small lymph nodes were displayed in the ileocecum area ( Figure 1 ).
Large and irregular ulcer that is consistent with ulcerative colitis being seen on the ileocecal valve.

When the colonoscopy reached the ileocecal valve area, the mucosa appeared ulcerated, and the surface was covered with a crypt abscess, showing "ulcerative colitis"-like changes ( Figure 2 ).
The appendiceal orifice is fully exposed with the aid of a transparent cap.

Finally, we reached the appendiceal cavity, in which a copious amount of pus and stones could be seen flowing out during the procedure ( Figure 4 ). Fluoroscopy revealed that the appendiceal lumen was severely dilated after successful cannulation, with a width of 10 mm, length of 8 cm, and an irregular shape ( Figure 5 ).

After clearance of the appendiceal lumen, a pigtail plastic stent with a size of 6 *French widths and 5 cm in length was successfully placed into the appendix cavity.
