Background And Aims:
Endoscopic hand-suturing (EHS) provides secure intraluminal mucosal closure and should decrease the risk of adverse events after gastric endoscopic submucosal dissection (ESD). We prospectively investigated the feasibility and safety of EHS after gastric ESD, particularly for preventing post-ESD bleeding.
Methods:
Patients scheduled for gastric ESD at 3 institutions were prospectively recruited. Just after ESD, the mucosal defect was closed by EHS. The primary outcome was endoscopic assessment of adequately sustained closure of the defect on postoperative day 3. Endoscopy was performed to assess maintenance of the closure for the primary outcome. During postoperative weeks 3 to 4, patients were interviewed as outpatients about any occurrence of delayed bleeding.
Results:
Data from 30 patients (15 each who did or did not take antithrombotic agents) were analyzed. Mucosal closure by EHS was completed in 29 of 30 cases (97%) and was well maintained on postoperative day 3 in 25 cases (84%). Emergency endoscopy was required for major postoperative bleeding in 3 cases (10%), including 1 in which suturing had been incomplete. Excluding 1 patient with a remnant stomach, the other 24 with sustained closure had no bleeding, regardless of whether they did or did not take antithrombotic agents (0/11 and 0/13, respectively). No serious adverse events occurred during EHS.
Conclusions:
Results show that EHS is feasible and safe with favorable outcomes. Provided that mucosal suturing is successfully completed and sustained, post-ESD bleeding can be decreased even in patients undergoing antithrombotic therapy. (Clinical trial registration number: UMIN 000033988.).
