Acupuncture and electroacupuncture for cyclic vomiting syndrome with tachygastria in an adult: A case report.

Abstract

Rationale: Cyclic vomiting syndrome (CVS) is characterized by recurrent episodes of acute vomiting lasting <1 week, occurring independently and chronically. Management typically involves lifestyle interventions, supportive care, and preventative medication. In rare cases, CVS persists for decades in adults, requiring a multidisciplinary approach to improve symptoms and quality of life.

Patient concerns: A 30-year-old male patient presented with a 7-year history of recurrent nausea and vomiting, which initially began in 2017. The episodes occurred without identifiable triggers such as alcohol or overeating, increasing in frequency from once every 4 months to 2 months. He expressed fear of severe deterioration, impacting his ability to eat freely, work, and enjoy his hobbies.

Diagnoses: He was diagnosed with CVS based on the Rome criteria. Cutaneous electrogastrography showed postprandial power decrease and tachygastria.

Interventions: Regular acupuncture treatments, including electroacupuncture at ST36 with 3 Hz, were administered twice a week for 3 weeks, followed by weekly sessions for 5 additional weeks.

Outcomes: Over 11 treatment sessions across 8 weeks, no nausea or vomiting was observed. The visual analog scale (VAS) score for subjective gastrointestinal discomfort decreased from 67 to 0 after 4 weeks. The Nausea Severity Scale (NSS) score dropped from 14 to 0 after 4 weeks. The Functional Dyspepsia-related QoL score decreased from 16 to 0 after 8 weeks. The Nepean Dyspepsia Index-Korean version decreased from 80 to 8 after 8 weeks. Furthermore, the patient expressed high satisfaction with the treatment, and no adverse events were observed.

Lessons: Acupuncture offers a significant and safe approach to relieving symptoms and enhancing the quality of life for patients with nausea and vomiting. Although this is a single case report, the findings suggest that acupuncture can improve treatment compliance and manage symptoms in adults with CVS. Further research, including clinical trials, is required to confirm these findings and understand the underlying mechanisms.
