In patients with chronic gastrointestinal ischemia, it is better to place a stent with a plastic outer layer than a metal stent with a chicken wire structure. This is evident from a study by Dutch researchers that was published in The Lancet Gastroenterology & Hepatology.
In the Netherlands, 1,600 people are diagnosed every year with chronic gastrointestinal ischemia, often caused by calcification of intestinal arteries. This causes chronic oxygen deficiency in the intestines and severe abdominal pain. The treatment consists of placing a stent in the narrowed arteries. With the metal stents with an open ‘chicken wire’ structure that are used, the vessel wall can grow into the stent, causing a new narrowing. That problem is prevented by a plastic covering on the stent.
The Dutch Mesenteric Ischemia Study Group conducted a study led by Prof. Dr. Marco Bruno (Erasmus MC) among 94 patients with chronic gastrointestinal ischemia in 6 hospitals. They were randomized to a metal stent or a stent with a plastic covering. After 2 years, the blood vessel with a metal stent became seriously narrowed again in more than 50% of the participants, while this was the case in less than 20% with the covered stent. The researchers hope that their results will lead to more widespread use of the covered stent and to adjustments in treatment guidelines.
