Reversibility of gastrointestinal motor abnormalities in chronic intestinal pseudo-obstruction.

A 43-year-old man with chronic intestinal pseudo-obstruction is presented. He had undergone two laparotomies in an attempt to eliminate the cause of repeated episodes suggestive of obstruction. Gastrointestinal manometry showed severe abnormalities compatible with the diagnosis of chronic intestinal pseudo-obstruction. Laboratory tests indicated the presence of intestinal malabsorption and villous atrophy. A gluten-free diet accompanied by 10 days of treatment with tetracycline and 2 short periods of treatment with cisapride led to gradual, but apparently complete, resolution of the pseudo-obstructive syndrome. Repeated manometric studies showed progressive normalization of both the fasting and postprandial upper gastrointestinal motor pattern.
