Favorable long-term outcomes of repeat endotherapy for small-intestine vascular lesions by double-balloon endoscopy

      GI bleeding secondary to small-intestine vascular lesions (SIVLs) is associated with rebleeding despite initial hemostasis by endotherapy applied at double-balloon endoscopy (DBE).


      To evaluate the long-term outcomes of DBE endotherapy of SIVL (as described by the Yano-Yamamoto classification). The impact of repeat DBE endotherapy for recurrent bleeding also was assessed.


      Retrospective cohort study. The mean (± standard deviation [SD]) follow-up period was 4.9 (± 1.7) years (range 2.4-9.1 years).


      Tertiary-care referral center.


      A total of 43 patients, who underwent 69 sessions of DBE endotherapy of SIVLs.


      DBE endotherapy.

      Main Outcome Measurements

      Frequency of overt rebleeding after the initial DBE endotherapy.


      Overt rebleeding occurred in 16 of 43 patients (37%). Patients with multiple SIVLs showed a significantly higher rate of overt rebleeding than did those with a solitary SIVL (12/23 [52%] vs 4/20 [20%]; P = .017). The trend toward frequency of rebleeding after the first DBE hemostasis appeared to be higher for patients with type 1a SIVLs than for those with type 1b or type 2 lesions: type 1a (8/16, 50%) versus type 1b (5/19, 26%) (P = .12) and type 1a (8/16, 50%) versus type 2 (2/7, 29%) (P = .31), respectively. In 12 of 16 patients (75%) who underwent repeat DBE endotherapy at each episode of overt rebleeding (median 3 times, range 2-6), the frequency of rebleeding decreased significantly after the first year of follow-up, as compared with the remaining 4 patients who did not undergo repeat DBE; mean (± SD) 0.12 (± 0.19) versus 0.52 (± 0.33) times per year per patient (P = .006).


      Single-center, retrospective study.


      Although the presence of multiple SIVLs was associated with rebleeding, repeat DBE endotherapy resulted in an improved long-term outcome in patients with refractory SIVL bleeding.
