Mather Hospital performs New York State’s first magnetic duodenal ileostomy (MagDI™) procedure for weight loss
Northwell Health's Mather Hospital announced on Wednesday that it has successfully performed New York State’s first magnetic duodenal ileostomy (MagDI™) procedure, marking a significant advancement in minimally invasive bariatric and gastrointestinal surgery. This revolutionary technique, which uses magnets to create an intestinal connection without cutting, stitching, or stapling, was performed on a patient experiencing acid reflux and insufficient weight loss after a previous sleeve gastrectomy. Northwell's Mather Hospital is also among the first in the Eastern United States to offer this cutting-edge treatment.

The MagDI procedure represents a remarkable leap forward in surgical innovation,” said Arif Ahmad, MD, FACS, director of bariatric and robotic surgery at Northwell’s Mather Hospital. “By eliminating the need for incisions, sutures, or staples at the joint, we’ve significantly advanced patient safety and comfort. The result is a minimally invasive approach that virtually removes the risk of bleeding or leakage, ushering in a new era for gastrointestinal surgery.
Long-Term Data on ESG Show Durable Weight Loss at 10 Years
A decade-long study from Weill Cornell Medicine shows that endoscopic sleeve gastroplasty (ESG) delivers sustained long-term weight loss without the need for weight-loss medications. Among 110 patients who only had ESG, the average total body weight loss (TBWL) at 10 years was 10.5%, with over half maintaining at least 5% TBWL.
