case_images: a Ultrasound showing bowel wall thickening of the ascending colon (arrow). b Abdominal computed tomography (CT) showing bowel wall thickening and increased CT value of panniculitis of the ascending colon (red arrowhead). c Follow-up CT after 2 weeks showing improvement in bowel wall thickening and an increased CT value of panniculitis of the ascending colon (yellow arrowhead).

case_images: Abdominal ultrasound and computed tomography (CT) revealed bowel wall thickening in the ascending colon, indicating panniculitis (shown in Fig. 1a, b). A follow-up CT performed 2 weeks after admission revealed not only an improvement in the thickness of the panniculitis in the ascending colon but also a reduction in previously elevated CT values (shown in Fig. 1c).
case_images: a-c First colonoscopy of polypectomy; mucosal defects were irrigated with a water jet to reduce oozing, and the resection site was sutured with endoscopic clips.

case_images: Post-resection mucosal defects were irrigated with tap water, and the resection site was secured with endoscopic clips (shown in Fig. 2).
case_images: Colonoscopy was performed 6 days after admission. a Ulcers at the site of cold snare polypectomy (CSP) with bowel wall thickening of the ascending colon. Black deposits are caused by the carbon in uremic drugs. b, c Excretion of pus was observed after application of biopsy forceps. d, e Follow-up colonoscopy 1 month after admission showing improvement of the ascending colon wall.

case_images: This is likely due to the phlegmonous colitis (shown in Fig. 3a-c). We further performed a follow-up colonoscopy 1 month after admission, which showed improvement in the ascending colon wall (shown in Fig. 3d, e).
