Assess the incidence and severity of internal hernia and bowel obstruction at one year in a U.S. population following use of the MagDI System to create side-to-side duodeno-ileal anastomoses.
Small bowel obstruction (SBO) following various abdominal and pelvic surgeries (0.4% - 13.9% at 5 years post-surgery) across obese and non-obese patients has been well studied in the scientific literature and found to be primarily due to intraperitoneal adhesions, with surgical technique (open surgery versus laparoscopic) cited as a key risk factor as reported in a retrospective population-based registry in Sweden (n=108,141). SBO incidence was reported as 3.2% for those undergoing bariatric surgery (n=1,896).
Given the MagDI System premarket clinical study (GTM-001) was conducted outside the U.S., FDA requires one post-market surveillance study to assess and characterize the incidence and severity of internal hernia and bowel obstruction in the U.S. intended use population treated with MagDI System. This study will be conducted through an observational patient registry and compare registry data to the premarket MagDI System clinical study data (GTM-001) and scientific literature. This post-market Registry Study was also a condition of the MagDI System FDA 510(k) clearances K242086 and K243359.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
1. Participant does not provide to be enrolled and followed in the registry.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
