Prospective study reveals that cine-MRI assessment of small bowel motility distinguishes pseudo-obstruction from megacolon, aiding critical surgical decision-making.
Background/Aims: Chronic intestinal pseudo-obstruction (CIPO), characterized by dilated small or large intestine on CT, has a high postoperative recurrence rate. In contrast, focal hypoganglionosis with adult-onset megacolon (FHAM) generally shows a good postoperative prognosis. This study aims to evaluate the utility of cine-MRI in differentiating between these 2 diseases by assessing small bowel (SB) motility and its correlation with clinical outcomes. Methods: The clinical features and outcomes of 41 prospectively enrolled patients suspected of having CIPO who underwent cine-MRI were reviewed. Multi-slice cine-MRI was conducted. Results: = 0.020) than in those with normal SB motility. Conclusions: Cine-MRI is useful in assessing SB motility that cannot be detected on CT. Its usefulness extends to aiding surgical decision-making, particularly in differentiating between FHAM and CIPO.
