Full text: M Halland et al Clinical Gastroenterol Hepatol 2018; 16: 1549-1555 provide an excellent review and practical recommendations for rumination syndrome.
The article describes the high prevalence which is ~0.8-0.9% of adults and ~5% of children. Some populations like patients with eating disorders and fibromyalgia have even higher rates.
Other key points:
- Long delay in diagnosis: patients “visit an average of 5 physicians over 2.7 to 4.9 years before being diagnosed correctly”
- The diagnosis is a clinical based on Rome IV criteria, though most patients undergo an esophagogastroduodenoscopy or barium study to rule out other disorders
- Best Practice Advice 1: Clinicians strongly should consider rumination syndrome in patients who report consistent postprandial regurgitation. Such patients often are labeled as having refractory gastroesophageal reflux or vomiting.
- Best Practice Advice 2: Presence of nocturnal regurgitation, dysphagia, nausea, or symptoms occurring in the absence of meals does not exclude rumination syndrome, but makes the presence of it less likely.
- Best Practice Advice 3: Clinicians should diagnose rumination syndrome primarily on the basis of Rome IV criteria after an appropriate medical work-up.
- Best Practice Advice 4: Diaphragmatic breathing with or without biofeedback is the first-line therapy in all cases of rumination syndrome.
- Best Practice Advice 5: Instructions for effective diaphragmatic breathing can be given by speech therapists, psychologists, gastroenterologists, and other health practitioners familiar with the technique.
- This article gives instructions on this technique: “Diaphragmatic breathing can be learned easily by putting a hand on the chest and on the abdomen during respiration, and only allowing the hand on the abdomen to move out with inspiration while the chest remains in position (Figure 3). We instruct patients to take breaths by protruding the abdomen while keeping the chest as stationary as possible. Each inhalation or exhalation should be slow and complete, aiming for 6 to 8 respirations per minute. We recommend diaphragmatic breathing for 15 minutes after each meal, or longer if the sensation of impending rumination remains. The technique also should be practiced in the absence of meals to become expert at the technique. Uncontrolled studies and case series have reported resolution or improvement in rumination symptoms after diaphragmatic breathing in 20%–66% of patients. Figure 3: The patient slowly inhales through the nose while protruding the abdomen and keeping the chest stationary. (B) The patient slowly exhales via the mouth and allows the abdomen to retract.”
- Best Practice Advice 6: Objective testing for rumination syndrome with postprandial high-resolution esophageal impedance manometry can be used to support the diagnosis, but expertise and lack of standardized protocols are current limitations.
- Best Practice Advice 7: Baclofen, at a dose of 10 mg 3 times daily, is a reasonable next step in refractory [adult] patients.
My take: This is a useful review article. Rumination needs to be considered particularly in patients with regurgitation, often labelled vomiting by families, that happens quickly after meals.
