Objective This experimental study was designed to assess the technical feasibility and benefits of our novel approach for transgastric NOTES (natural orifice translumenal endoscopic surgery) cholecystectomy. Methods Four pigs were subjected to NOTES cholecystectomy by the combined transgastric and transparietal approach using two flexible endoscopes. Under the guidance of a transparietal endoscope inserted through a trocar placed in the right upper abdomen, a gastrotomy was constructed, and a peroral endoscope was advanced into the peritoneal cavity through the gastrotomy and moved on retroflexion toward the gallbladder. Gallbladder excision with ligation of the cystic artery and duct using endoclips was performed using the peroral endoscope. After gastrotomy closure with endoclips inside the stomach, intraperitoneal lavage were carried out using the transparietal endoscope. Results A complete gallbladder excision was carried out without major adverse events in all cases. The gastrotomies were successfully closed using endoclips ( n = 3) or by the omentum‐plug method ( n = 1). Conclusion This approach is technically feasible and makes transgastric NOTES cholecystectomy easier and safer.
