The rumination syndrome: clinical and manometric profile, therapy, and long-term outcome

The aims of this study were to investigate the diagnostic studies necessary to identify rumination syndrome and the long-term therapeutic outcomes of patients with rumination syndrome. Sixteen patients with rumination were evaluated between 1989 and 1995. Esophageal motility, gastric emptying, upper gastrointestinal motility, and electrogastrography of all patients were reviewed; follow-up information about their current status was available from 10 of the 16 patients. Duration of symptoms was 77.2 months and the mean age was 28.5 years at the time of diagnosis. Esophageal and upper gastrointestinal motility, gastric emptying, and electrogastrographic studies were all normal. Mean lower esophageal pressure was 12.7 mm Hg and three of the 16 patients had a decreased pressure of less than 6 mm Hg. Ten patients were followed for a mean duration of 31.2 months. Five of 10 patients used biofeedback and relaxation techniques and reported subjective improvement. Our results indicate that rumination syndrome is often confused with a gastric motility disorder and diagnosis is possible if one is aware of this condition. Although there is not a definitive management protocol for this condition, reassurance and education of the patient and the family are crucial first steps followed by behavioral and relaxation programs.
