What side effects are associated with this type of intervention?

Common treatments for gastroparesis, including prokinetic agents like metoclopramide and erythromycin, gastric electrical stimulation, and endoscopic procedures like G-POEM, have various side effects. Metoclopramide can cause tardive dyskinesia, while erythromycin may lead to gastrointestinal disturbances and antibiotic resistance. Gastric electrical stimulation can result in infection, lead migration, and pain at the implantation site. Endoscopic procedures like G-POEM can cause perforation, bleeding, and infection. Transpyloric stenting with LAMS, which keeps the pylorus open to facilitate gastric emptying, may have risks such as stent migration, occlusion, and local irritation or ulceration.

What prior FDA approvals exist?

The FDA has approved several pharmacologic treatments for gastroparesis, including metoclopramide, which is commonly used to increase gastric emptying. Other drugs like domperidone and erythromycin are also used, although they may not have specific FDA approval for gastroparesis. Cisapride was previously used but is now limited due to safety concerns. Procedural interventions such as gastric per-oral endoscopic pyloromyotomy (GPOEM) and transpyloric stenting with lumen apposing metal stent (LAMS) are being studied to facilitate gastric emptying by keeping the pylorus open, offering potential alternatives for patients with refractory symptoms.

What other types of research exist?

Promising novel alternatives to Transpyloric Stenting with LAMS for gastroparesis patients include Gastric Per-Oral Endoscopic Pyloromyotomy (G-POEM), which involves endoscopic cutting of the pyloric muscle to improve gastric emptying, and the use of prokinetic agents like prucalopride and relamorelin, which enhance gastrointestinal motility. Additionally, advancements in gastric electrical stimulation (GES) devices, which deliver electrical pulses to stimulate gastric contractions, are also being explored as potential treatments.

Study Summary

This trial will test whether a metal stent placed across the pylorus predicts success of a later endoscopic pyloromyotomy for patients with refractory gastroparesis.

Who is the study for?

This trial is for adults over 18 with gastroparesis that hasn't improved with standard treatments or those who can't take them due to allergies. It's open to patients with diabetic, idiopathic, or post-surgical forms of the condition confirmed by a gastric emptying study. People can't join if they've had certain GI surgeries, cancer in the stomach area, are unstable for endoscopy procedures, have liver cirrhosis, are pregnant/breastfeeding, or have significant blood clotting issues.Check my eligibility

What is being tested?

The study is testing whether placing a transpyloric stent (a type of tube) across the pylorus (the stomach's exit) predicts success for a later procedure called G-POEM in treating severe gastroparesis. Participants will be randomly assigned to receive either the actual stenting procedure or a sham (fake) procedure as part of this forward-looking research.See study design

What are the potential side effects?

Potential side effects from transpyloric stenting may include discomfort at the stent site, risk of infection, bleeding during placement and possible migration or blockage caused by the stent. The severity and occurrence can vary among individuals.

Other Research

Common treatments for gastroparesis include pharmacologic agents like metoclopramide, which enhances gastric motility by stimulating muscle contractions in the stomach, and erythromycin, which mimics the action of motilin to promote gastric emptying. Endoscopic and surgical interventions, such as gastric per-oral endoscopic pyloromyotomy (G-POEM) and transpyloric stenting with lumen apposing metal stent (LAMS), aim to improve gastric emptying by addressing pyloric dysfunction. These procedures keep the pylorus open, allowing for better passage of stomach contents into the small intestine. This is crucial for gastroparesis patients as it helps alleviate symptoms like nausea, vomiting, and abdominal pain, thereby improving their quality of life.
