A case of colonic fecal impaction caused by excessive dietary fiber intake that was endoscopically treated with intra-fecal injection of a bowel-cleansing agent

This is the authors' abstract. We don't add key points for this paper.

Background and Aim: A 75-year-old man who had eaten half a head of chopped raw cabbage (approximately 600 g) daily was suffering from the left lower pain, abdominal fullness, and constipation. He was diagnosed with colonic ileus and obstructive colitis due to a fecal impaction in the sigmoid-descending junction. During colonoscopy, a tapered catheter was repeatedly inserted into the impacted feces to inject a bowel-cleansing agent. Finally, the feces were broken to be fragmented enough to path the endoscope through. After the procedure, his symptoms were immediately relieved. Relevance for Patients: Excessive dietary fiber intake can induce fecal ileus. Endoscopic treatment with intra-fecal injection of a bowel-cleansing agent is useful and worth attempting for disimpaction of feces.
