The use of water immersion technique during device-assisted (single-balloon) enteroscopy to treat actively bleeding jejunal Dieulafoy's lesion
Dieulafoy’s lesion (DL) is an uncommon but potentially life-threatening condition, which can result in sudden, massive gastrointestinal bleeding. The water immersion technique can be helpful in localizing the source of active bleeding during an endoscopy. Herein, we present a case of gastrointestinal bleeding due to jejunal DL found on a video capsule endoscopy (VCE). We describe the use of the water immersion technique in localization and treatment of actively bleeding DL during single-balloon enteroscopy.Multicenter case series of patients with small-bowel angiodysplasias treated with a small-bowel radiofrequency ablation catheter
GI angiodysplasia is the most common cause of small-bowel bleeding. Argon plasma coagulation (APC) is preferred for ablation because of its availability, ease of use, and perceived safety, but it has limitations. An instrument capable of repeated use through the enteroscope, which covers more area of intestinal mucosa per treatment with low risk of damage to healthy mucosa, and which improves ablation, is desirable. A series of patients treated with a through-the-scope radiofrequency ablation (RFA) catheter is reported.
