Could a gut zapping procedure free diabetics from insulin?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

(Prior laparoscopic sleeve gastrectomy (LSG) will not be an exclusion). 9. History of pancreatitis (acute or chronic). 10. Known diabetic gastroparesis. 11. Persistent anaemia, defined as haemoglobin ≤ 9 g/dL 12. Known active hepatitis or active liver disease. 13. Acute gastrointestinal illness in the previous 7 days. 14. Known history of severe irritable bowel syndrome, radiation enteritis or other inflammatory bowel disease, such as Crohn's disease. 15. Known history of a structural or functional disorder of the esophagus that may impede passage of the device through the gastrointestinal tract or increase risk of esophageal damage during an endoscopic procedure, including moderate-severe (Grade C or D) esophagitis, dysphagia due to achalasia or stricture/stenosis, esophageal varices, esophageal perforation, or any other disorder of the esophagus. 16. Upper gastrointestinal conditions such as active ulcers, polyps, varices, strictures, congenital or acquired duodenal telangiectasia. 17. Current use of anticoagulation therapy (e.g. warfarin) or direct-acting oral anticoagulants (e.g. rivaroxaban, apixaban, edoxaban and dabigatran) that cannot be discontinued for 3-5 days before and 7 days after the procedure. 18. Current use of P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) that cannot be discontinued for 5 days before and 7 days after the procedure. 19. Unable to discontinue non-steroidal anti-inflammatory drugs (NSAIDs) during treatment through 4 weeks following the procedure. Use of acetaminophen and low dose aspirin is allowed. 20. Use of systemic glucocorticoids (excluding topical or ophthalmic application or inhaled forms) for more than 10 consecutive days within 12 weeks prior to the baseline visit. 21. Use of drugs known to affect gastrointestinal motility (e.g. Metoclopramide) 22. Use of weight loss medications such as Sibutramine (e.g. Meridia), Orlistat (e.g. Xenical), Phentermine or over-the-counter weight loss medications (prescription medication) 23. Significant cardiovascular disease, including known history of valvular disease, or myocardial infarction, heart failure, transient ischemic attack, or stroke within 6 months prior to the Screening Visit. 24. Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2. 25. Uncontrolled thyroid disease 26. Mean of 3 separate blood pressure measurements \>180 mmHg (systolic) or \>100 mmHg (diastolic). 27. Estimated glomerular filtration rate (eGFR) ≤ 45 ml/min/1.73m2 (estimated by MDRD). 28. Known immunocompromised status, including but not limited to individuals who have undergone organ transplantation, chemotherapy, or radiotherapy within the past 12 months, who have clinically significant leukopenia, who are positive for the human immunodeficiency virus (HIV) or whose immune status makes the participant a poor candidate for clinical trial participation in the opinion of the investigator. 29. Active illicit substance abuse or alcoholism (\>2 drinks/day regularly) 30. Active malignancy within the last 5 years (excluding non-melanoma skin cancers) 31. Active systemic infection 32. Women who are currently breastfeeding. 33. Pregnancy or wish to get pregnant in the next year. 34. Participating in another ongoing clinical trial of an investigational drug or device. 35. Any other mental or physical condition which, in the opinion of the study investigator, makes the participant a poor candidate for clinical trial participation. 36. Critically ill or has a life expectancy \< 3 years. 37. Use of heart pacemaker or other electronic device implants 38. General contraindications to deep or conscious sedation, general anesthesia, high risk as determined by anesthesiologist (e.g., ASA score 4 or higher), or contraindications to upper GI endoscopy.
