Aims To evaluate the use 3D endoscopic visualization system to perform endoscopic sleeve
gastroplasty
Methods Patients consecutively operated from September to November 2021 with a 3D-HD endoscopic
visualization system (MDTK MonoStereo; Taiwan) were prospectively collected. Patients'
demographic data, preoperative anthropometrics data; operative time, number of sutures
made, intraoperative and postoperative complications, and follow-up data were prospectively
recorded and retrospectively reviewed. Additionally, a questionnaire was completed
by the endoscopist evaluating the subjective impression of visualization and handling
Results Seven patients (age 27 to 52 years old, 3 male) underwent endoscopic sleeve gastroplasty
using 3D-HD endoscopic visualization system. Mean preoperative body mass index was
33kg/m2, mean operative time was 52 minutes with a mean of 5 sutures (4–7) used. No
30-day complications were reported and patients lost 8% total body weight loss after
1 month. The endoscopist reported better visualization, better depth perception and
no nausea with the 3D visualization system.
Conclusions 3D-HD endoscopic visualization system seems to provide potential advantages in endoscopic
sleeve gastroplasty. This initial experience is promising but must be confirmed by
larger series.
