Endoscopic transgastric pure NOTES cholecystectomy with naso-gallbladder drainage tube placement and injection of a hyaluronic acid mixture (with Video)

摘要

Endoscopic transgastric pure natural orifice translumenal endoscopic surgery (NOTES) cholecystectomy is a difficult procedure, and most human female cases are performed as hybrid NOTES, using a transvaginal route. We tried a transgastric pure NOTES procedure without laparoscopic procedure in an animal study after placing an endoscopic naso-gallbladder drainage (ENGBD) tube and injecting a hyaluronic acid (HA) mixture.
