Lumen Apposing Metal Stent Market - Strategic Insights and Forecasts (2026-2031)

The Lumen Apposing Metal Stent (LAMS) market is forecast to grow at a Compound Annual Growth Rate (CAGR) of 5.9%. This growth is expected to increase the market value from USD 3.9 billion in 2026 to USD 5.2 billion in 2031.

LAMS are primarily used to establish stable, direct connections between internal gastrointestinal tract structures, enabling access and drainage of adjacent lumens without open surgery. They are commonly employed for draining pancreatic fluid collections, abscesses, or gallbladder infections, especially in patients unsuitable for conventional surgery. Their design minimizes leakage and stent migration, promoting efficient fluid and tissue drainage.

Market demand for LAMS is significantly driven by the high incidence of acute pancreatitis, with 23%–61% of cases developing pancreatic fluid collections (PFCs). A substantial portion of these PFCs, such as ~18.2% of pseudocysts and ~35.7% of walled-off necrosis cases, require intervention and drainage. This expanding addressable patient population, including a rising trend in pediatric pancreatitis, underpins the market's growth.

Innovation in electrocautery-enhanced delivery systems is significantly impacting LAMS deployment, enabling one-step deployment of stents. This advancement simplifies endoscopic ultrasound-guided drainage procedures for conditions like pancreatic fluid collections. Furthermore, the large internal diameter of LAMS allows for both efficient fluid drainage and the passage of an endoscope for additional therapeutic procedures such as debridement.

Beyond their primary use for pancreatic fluid collections, LAMS are seeing expanding clinical applications, including gallbladder drainage in high-risk surgical patients. The report also indicates various off-label uses for LAMS. This suggests a growing versatility and potential for these stents in a broader range of gastrointestinal conditions.

The future outlook for LAMS is strong, supported by clinical trials demonstrating their effectiveness in promoting drainage and maintaining lumen patency over extended periods. LAMS serve as a minimally invasive means to provide therapeutic connectivity, offering a crucial alternative for patients unable to undergo open surgery. Their continued innovation and expanding clinical applications position them as a vital tool in endoscopic interventions.
