PURPOSE: This study was designed to determine the value of intravenous
neostigmine in achieving adequate colonic decompression in patients w
ith Ogilvie's syndrome. METHODS: A prospective study was undertaken in
12 consecutive patients (median age, 60 (range, 38-98) years) with co
ntrast enema-proven Ogilvie's syndrome (median duration, four (range,
two-nine) days) RESULTS: Satisfactory clinical decompression of large
bowel distention was attained in II patients, although one required co
lectomy for subsequent recurrence and ischemia. CONCLUSION: These resu
lts support the theory that many cases of Ogilvie's syndrome are the r
esult of excessive large bowel parasympathetic suppression rather than
sympathetic overactivity.
