NCT04287647

Brief Summary

This is a prospective sham study to investigate the role of transpyloric stenting with lumen apposing metal stent (LAMS) as a predictor for clinical response to gastric per-oral endoscopic pyloromyotomy (GPOEM) for refractory gastroparesis. The study hypothesizes that clinical improvement with transpyloric stenting in patients with refractory gastroparesis is a predictor of subsequent clinical success of GPOEM.

Outcome Measures

Primary Outcomes (1)

  • Clinical response will be assessed by the gastroparesis cardinal symptom index (GCSI) scores

    GCSI assessment is based off an average of 16 questions that are scored from 0-5, with higher scores indicating a worse clinical outcome.

    1-2 years

Secondary Outcomes (6)

  • Age

    1-2 years

  • Weight

    1-2 years

  • Height

    1-2 years

  • BMI

  • Adverse events

  • +1 more secondary outcomes

Study Arms (2)

Transpyloric stent

ACTIVE COMPARATOR

In this group, patient's will be randomized to receive a transpyloric stent for treatment of refractory gastroparesis. They will be blinded for one month after stent placement as to whether they received a stent or sham.

Device: Transpyloric stent

Sham

SHAM COMPARATOR

In this group, patient's will be randomized to sham for treatment of refractory gastroparesis. They will be blinded for one month after stent placement as to whether they received a stent or sham.

Other: Sham

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients greater than 18 years of age with gastroparesis refractory to standard medical therapy (lifestyle and diet modifications, prokinetics) or contraindication to standard therapies (e.g. allergies to prokinetic agents)
  • Patients with diabetic, idiopathic or post-surgical gastroparesis
  • Patients with confirmed diagnosis of gastroparesis via gastric emptying study (abnormal gastric emptying will be defined as ≥10 % residual activity at 4 h on a standardized nuclear medicine TC-99 m sulfur colloid solid-phase gastric emptying study)

You may not qualify if:

  • Patients with prior history of gastroenteric anastomosis or any GI surgeries with pyloric involvement
  • Patients with gastroesophageal malignancy
  • Patients who are unable to tolerate upper endoscopy secondary to cardiopulmonary instability or other contraindications to endoscopy
  • Patients with cirrhosis
  • Patients who are pregnant or breastfeeding
  • Patients with uncorrectable coagulopathy defined by INR \>1.5 or platelets \<50
