Biological Optimization Versus Standard Care in Post-POEM Achalasia Patients (BIO-POEM) (BIO-POEM 1)

May 27, 2026 updated by: Mohan Ramchandani, Asian Institute of Gastroenterology, India

Randomized Controlled Trial of Structured Biological Optimization Versus Standard Care With Embedded Prospective Registry in Post-POEM Achalasia Cardia Patients.

This study aims to evaluate whether a structured biological optimization program can improve reflux symptoms and overall recovery in patients with achalasia cardia who previously underwent Peroral Endoscopic Myotomy (POEM). Although POEM is highly effective for relieving swallowing difficulty, many patients develop gastroesophageal reflux disease (GERD) after the procedure and remain dependent on long-term acid suppressive medications such as proton pump inhibitors (PPIs).

The BIO-POEM study will compare structured biological optimization with standard post-POEM care in patients with objectively confirmed pathological reflux after POEM. The intervention includes reflux-oriented dietary counseling, micronutrient assessment and correction, Helicobacter pylori testing and eradication when indicated, lifestyle optimization, and structured review and tapering of PPI/PCAB therapy.

The study includes two components:

A randomized controlled trial enrolling post-POEM patients with objectively confirmed reflux.

A parallel prospective observational registry enrolling symptomatic post-POEM patients who are unable to undergo reflux testing or who remain symptomatic despite low acid exposure.

The primary objective is to determine whether structured biological optimization reduces GERD symptom burden at 12 months compared with standard care. Secondary objectives include evaluation of dyspepsia symptoms, nutritional recovery, quality of life, reduction in PPI dependence, and exploratory assessment of gut microbiome changes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Structured Biological Optimization
Participants in this arm will receive a structured, protocol-driven biological optimization program in addition to standard post-POEM follow-up. The intervention includes reflux-oriented dietary counseling, lifestyle modification, micronutrient assessment and correction (including vitamin D, B12, iron, calcium, and pre-albumin where deficient), Helicobacter pylori testing and eradication where indicated, and a structured, stepwise de-escalation of proton pump inhibitor (PPI) or potassium-competitive acid blocker (PCAB) therapy based on clinical response and physician assessment.
A structured, protocol-driven multimodal intervention designed to optimize post-POEM recovery in patients with achalasia cardia. The intervention includes individualized reflux-oriented dietary counseling (meal timing, portion control, and trigger food modification), lifestyle optimization (sleep hygiene, weight management, and physical activity guidance), systematic evaluation and correction of micronutrient deficiencies (including vitamin D, vitamin B12, iron, calcium, magnesium, and pre-albumin where indicated), Helicobacter pylori testing with eradication therapy when positive, and a structured, stepwise protocol for proton pump inhibitor (PPI) or potassium-competitive acid blocker (PCAB) de-escalation guided by symptoms and clinical assessment. The intervention is delivered as a standardized care pathway integrated into routine post-POEM follow-up.

  • BIO-POEM Intervention
  • Post-POEM Biological Optimization Protocol
  • Structured Post-POEM Optimization Program BIO-POEM Care Pathway
Active Comparator: Standard Post-POEM Care
Participants in this arm will receive routine post-POEM care as practiced at the study center. Management will be symptom-driven and may include proton pump inhibitor (PPI) or PCAB therapy as clinically indicated. No structured dietary, micronutrient, or deprescribing protocol will be applied beyond standard clinical practice. Follow-up assessments and outcome evaluations will be performed in the same manner as the intervention arm.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) Score From Baseline to 12 Months
Time Frame: Baseline and 12 months

The primary outcome is the change in Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score from baseline to 12 months after randomization in post-POEM patients with objectively confirmed pathological reflux.

The GERD-HRQL questionnaire is a validated reflux-specific symptom assessment scale with total scores ranging from 0 to 50, where higher scores indicate worse reflux symptoms and poorer reflux-related quality of life.
