S Kurasawa et al. JPGN Reports. 2026; DOI: 10.1002/jpr3.70188. Open Access! Endoscopic ischemic polypectomy for small intestinal polyps in a 7-year-old girl with juvenile polyposis syndrome
Background: “Funayama et al.4 described the technique of endoscopic ischemic polypectomy (EIP) in detail in both pediatric and adult patients with Peutz–Jeghers syndrome (PJS). Subsequently, EIP was reported to be a safe and effective treatment for 269 small intestinal polyps in 22 pediatric PJS cases.5” Here the authors describe the use of this technique for a child with juvenile polyposis syndrome (JPS).
Key findings:
- During a two-hour double-balloon enteroscopy (DBE) for a 7 yo child, “17 pedunculated polyps, all with a visually assessed size range of 7–15 mm, EIP was performed using the “crossed-clip strangulation method,” in which the first hemostatic clip was deployed with the aid of a distal attachment and rotated 90°, followed by placement of a second clip crossing the first at a 90° angle (Figure 1)…Subsequently, anemia and hypoalbuminemia did not recur, and growth was satisfied.”



(A) Pedunculated polyp in the small intestine. (B) The first hemostatic clip was placed on the stalk of the polyp. (C) A second hemostatic clip was placed on the stalk of the polyp at a 90-degree angle to the first clip.
Discussion Points:
- “EIP does not involve electrocautery, eliminating the risk of thermal injury and offering a safer alternative for small bowel lesions.”
- “A limitation of EIP is the inability to retrieve resected polyps…It should only be used for lesions that appear clearly benign.”
- There is a risk of detached polyps migrating into the lower gastrointestinal tract and inducing intussusception. This can be mitigated by managing distal small intestinal polyps first.
My take: EIP appears to be useful for inidividuals with numerous small intestinal polyps.
