Aim: To investigate the feasibility and safety of Natural orifice trans-umbilical endoscopic cholecystectomy with a water-jet hybrid-knife in a non-survival porcine model.
Methods: Pure natural orifice transluminal endoscopic surgery (NOTES) cholecystectomy was performed on three non-survival pigs, by transumbilical approach, using a water-jet hybrid-knife. Under general anesthesia, the following steps detailed the procedure: (1) incision of the umbilicus followed by the passage of a double-channel flexible endoscope through an overtube into the peritoneal cavity; (2) establishment of pneumoperitoneum; (3) abdominal exploration; (4) endoscopic cholecystectomy: dissection of the gallbladder performed using water jet equipment, ligation of the cystic artery and duct conducted using nylon loops; and (5) necropsy with macroscopic evaluation.
Objectives: The role of carbon dioxide (CO2) insufflation during endoscopic retrograde cholangiopancreatography (ERCP) is debated. A meta-analysis was performed to evaluate the efficacy and safety of CO2 insufflation for ERCP.
Methods: Searches were conducted in multiple databases composed of Pub-Medline, EMBASE, the Cochrane Library, science citation index expanded, Google scholar, and CNKI China series full-text database.
