Treatment of acute nontoxic megacolon during colonoscopy: tube placement versus simple decompression.

The study compares the efficacy of colonoscopic decompression versus decompression and tube placement in the treatment of Ogilvie's syndrome. Nine patients were treated with a single colonoscopic decompression which resulted in four recurrences. In contrast, there were no recurrences observed in 11 patients who underwent decompression and subsequent tube placement (p less than 0.05). There was no morbidity observed from either decompression or tube placement. Tube placement added less than 10 min of additional procedure time to the colonoscopy. The tube utilized in this study was an enteroclysis tube with sideholes cut in the distal 20 cm. The tube was easily inserted over a Teflon-coated flexible guide wire inserted through the colonoscope into the cecum following decompression. This study demonstrates that colonoscopic decompression followed by tube placement is the preferred treatment modality for acute nontoxic megacolon.
