Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Endoscopic per-oral pyloromyotomy (POP)
Participants will undergo Endoscopic per-oral pyloromyotomy (POP).
|
Per-oral pyloromyotomy (POP), alternatively knows as gastric per-oral endoscopic myotomy (G-POEM), accomplishes longitudinal division of the pylorus using an endoscope.
This procedure involves utilizing endoscopic electrosurgical knife to make an incision in the gastric mucosa and develop a submucosal tunnel to visualize the pyloric ring.
The pyloric ring is divided longitudinally, and the mucosotomy incision is sealed with endoscopic clips.
|
Sham Comparator: Sham / Control Arm
Participants will undergo a diagnostic esophagogastroduodenoscopy (EGD) without pyloric disruption.
Following the 12-week blinded trial period, these participants will be unblinded and offered Endoscopic per-oral pyloromyotomy (POP) if they remain symptomatic.
|
Per-oral pyloromyotomy (POP), alternatively knows as gastric per-oral endoscopic myotomy (G-POEM), accomplishes longitudinal division of the pylorus using an endoscope.
This procedure involves utilizing endoscopic electrosurgical knife to make an incision in the gastric mucosa and develop a submucosal tunnel to visualize the pyloric ring.
The pyloric ring is divided longitudinally, and the mucosotomy incision is sealed with endoscopic clips.
While under general anesthesia, a standard gastroscope is introduced and a diagnostic upper endoscopy is performed.
The operator talks through the procedure steps as if completing POP.
The gastroscope is withdrawn and the patient is extubated.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Gastroparesis Cardinal Symptom Index (GCSI)
Time Frame: Baseline, 12 weeks post-procedure
|
Change in Gastroparesis Cardinal Symptom Index (GCSI) at Baseline to 12 weeks post-procedure.
Possible scores range from 0 (None) to 5 (Very Severe).

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Gastric Emptying
Time Frame: Baseline, 12 weeks post-procedure
|
Change in gastric emptying as measured by a standardized 4-hour solid scintigraphic gastric emptying study at Baseline to 12 weeks post-procedure
|
Baseline, 12 weeks post-procedure
|
36-Item Short Form; Quality of Life Survey
Time Frame: Baseline,12 weeks post-procedure
|
Change in 36-Item Short Form Survey (SF-36) score from Baseline to 12 weeks post-procedure.
The weighted sums of responses to questions in the survey produce eight separate scales which are scored from 0-100, with zero indication maximum disability and one hundred indicating no disability in that domain.
