ARTICLE HIGHLIGHTS
Research background

Rumination syndrome (RS) is a relatively common yet underdiagnosed condition.

Research motivation

There is no consensus on how to treat patients diagnosed with runination syndrome.

Research objectives

Our objectives are to systematically review the literature on the efficacy of treatment options for adults with RS.

Research methods

We conducted a systematic review according to PRISMA guidelines. We searched Medline (1946 to February 2019), EMBASE (1947 to February 2019), PsycINFO (1806 to February 2019) and Cochrane central register of controlled trials for articles discussing treatment options for adult patients (> 18 years) with RS. All relevant articles were accessed in full text. We extracted data on study designs, patient profiles, duration of symptoms, follow up periods, date, diagnostic criteria, interventions and outcomes. Risk of bias assessment was carried out independently by 3 reviewers via Cochrane Risk of Bias tool and Newcastle Ottawa Scale for RCTs and Cohort studies respectively.

Research results

12 articles were identified. The strongest evidence pointed towards diaphragmatic breathing (DB), and less so for baclofen. A total of 254 patients were included in the analysis.

Research conclusions

DB has the strongest evidence for efficacy in adults with RS.

Research perspectives

The quality of the evidence is still weak. More research needs to be done in this field.
