    Description

    An 80-year-old woman with type 2 diabetes and hypertension was admitted to hospital with lethargy and confusion. A collateral history revealed she suffered from chronic constipation and had not opened her bowels ‘for a few days’. On examination, she was in urinary retention. A catheter was inserted and she was started on treatment for a urinary tract infection.

    Subsequently, the patient became tachycardic and hypotensive. Abdominal examination revealed generalised tenderness and hard faecal matter per rectum. Blood tests showed raised inflammatory markers with C reactive protein of 298 mg/L and a white cell count of 18.3×109/L.

    CT of the abdomen and pelvis showed marked rectosigmoid faecal impaction, compression of the urinary bladder (figure 1) and inflammatory changes in the wall of the rectum and lower sigmoid, consistent with a diagnosis of stercoral colitis (figures 2 and 3). The patient was treated with enemas and intravenous antibiotics; despite this, she continued to deteriorate and, given the high operative risk, was deemed unsuitable for surgery and subsequently died.

    Stercoral colitis is an uncommon but important complication of chronic constipation. A faecaloma forms, causing distension of the colonic lumen, which decreases the blood supply to the area,1 causing a colitis that can progress to ulceration and perforation. A CT scan often shows the classical appearance of a thickened rectum impacted with faeces, dilation of the sigmoid colon and fat stranding of the adjacent bowel.2

    Management involves prevention of constipation, decompression of the rectum and surgical intervention in those with signs of perforation.3

    Learning points

    • Stercoral colitis is an uncommon and often fatal complication of chronic constipation.

    • It should be considered in all patients who present with abdominal pain and chronic constipation, and especially in the elderly and those with urinary retention.

    • CT scan is the modality of choice for diagnosis, and prompt surgical assessment with decompression of the bowel can avoid peritonitis and colonic perforation.
