PURPOSE: In this study, we sought to determine the outcome of patients
with ischemic colitis, comparing patients with segmental disease with
those with total colonic ischemia. METHODS: Patients with the diagnos
is of ischemic colitis over the past six years were selected and revie
wed for demographics, presenting symptoms, diagnosis, and treatment. R
ESULTS: Forty-three consecutive patients with ischemic colitis were id
entified and were grouped into those with segmental ischemic colitis a
nd total colonic ischemia. Mean age was 68.8 years; 28 of 43 patients
(65 percent) were males. Diagnosis was established by colonoscopy in 3
1 of 43 patients (72 percent), whereas in the remainder, diagnosis was
made in the operating room. Ischemic colitis developed in the hospita
l in 17 of 43 patients (40 percent) during admission for an unrelated
illness. In 6 of 43 (14 percent) of these patients, ischemic colitis d
eveloped following surgery. Thirty-one of 43 patients (72 percent) wer
e found to have segmental colitis, 11 of 31 patients (35 percent) were
successfully managed nonoperatively. Segmental colitis was present in
31 of 43 patients (72 percent), and 12 of 31 (35 percent) of these pa
tients were successfully managed nonoperatively. In the patients with
segmental colitis who required surgery, the 30-day mortality rate was
22 percent. Among 12 of 17 patients (71 percent) with segmental ischem
ia treated by resection and stoma, 9 of 12 (75 percent) underwent even
tual stoma closure. All 12 patients with total colonic ischemia requir
ed surgery, and 9 of 12 patients (75 percent) died. CONCLUSION: Ischem
ic colitis occurs commonly during an unrelated hospital admission and
following previous surgery. Most patients treated by resection and sto
ma undergo stoma closure. Total colonic ischemia carries a worse progn
osis than segmental colonic ischemia.
