Abstract
Background:

Current endoscopic methods in the control of acute nonvariceal bleeding have a small but clinically significant failure rate. The role of over-the-scope clips (OTSCs) as the first treatment has not been defined.

Objective:

To compare OTSCs with standard endoscopic hemostatic treatments in the control of bleeding from nonvariceal upper gastrointestinal causes.

Design:

A multicenter, randomized controlled trial. (ClinicalTrials.gov: NCT03216395)

Setting:

University teaching hospitals in Hong Kong, China, and Australia.

Patients:

190 adult patients with active bleeding or a nonbleeding visible vessel from a nonvariceal cause on upper gastrointestinal endoscopy.

Intervention:

Standard hemostatic treatment (n = 97) or OTSC (n = 93).

Measurements:

The primary outcome was 30-day probability of further bleeds. Other outcomes included failure to control bleeding after assigned endoscopic treatment, recurrent bleeding after initial hemostasis, further intervention, blood transfusion, and hospitalization.

Results:

The 30-day probability of further bleeding in the standard treatment and OTSC groups was 14.6% (14 of 97) and 3.2% (3 of 93), respectively (risk difference, 11.4 percentage points [95% CI, 3.3 to 20.0 percentage points]; P = 0.006). Failure to control bleeding after assigned endoscopic treatment in the standard treatment and OTSC groups was 6 versus 1 (risk difference, 5.1 percentage points [CI, 0.7 to 11.8 percentage points]), respectively, and 30-day recurrent bleeding was 8 versus 2 (risk difference, 6.6 percentage points [CI, −0.3 to 14.4 percentage points]), respectively. The need for further interventions was 8 versus 2, respectively. Thirty-day mortality was 4 versus 2, respectively. In a post hoc analysis with a composite end point of failure to successfully apply assigned treatment and further bleeds, the event rate was 15 of 97 (15.6%) and 6 of 93 (6.5%) in the standard and OTSC groups, respectively (risk difference, 9.1 percentage points [CI, 0.004 to 18.3 percentage points]).

Limitation:

Clinicians were not blinded to treatment and the option of crossover treatment.

Conclusion:

Over-the-scope clips, as an initial treatment, may be better than standard treatment in reducing the risk for further bleeding from nonvariceal upper gastrointestinal causes that are amenable to OTSC placement.
