Colonoscopic decompression should be used before neostigmine in the treatment of Ogilvie's syndrome.

Although the success rate of neostigmine treatment was significantly lower in our homogeneous groups, no significant decrease was determined in terms of hospital stay, intensive care unit stay, and requirement of colostomy compared with colonoscopic decompression. By comparison, colonoscopic decompression, which was performed by experienced endoscopists as a first-line treatment option, was more effective as an initial therapy and was more effective at avoiding a second treatment modality.
