89

Results

The en-bloc resection rate was 100%. The rate of DPPB after CSP was 0%, however, DPPB after conversion to HSP occurred in 1 case (33.3% (1/3)).

Baseline Characteristics

The total number of patients was 89, with a mean age of 70.5 years. In all, 15 patients were receiving antithrombotic therapy

Participant flow

During the study period, 89 consecutive patients were prospectively enrolled.

Adverse events

There was no case of perforation. The rate of immediate bleeding during CSP was 28.9% (33/114), and all cases of immediate bleeding could be adequately controlled by hemostasis clipping.
The rate of DPPB after CSP was 0%; however, DPPB after conversion to HSP occurred in 1 case (33.3% (1/3)).

Outcome measures

The primary outcome measure was the incidence of bleeding (DPPB and immediate bleeding).The rate of DPPB after CSP was 0%. The rate of immediate bleeding during CSP was 28.9%.
