Hybrid transvaginal cholecystectomy: a novel approach

Natural Orifice Transluminal Endoscopic Surgery (NOTES) allows cholecystectomy to be performed by means of a flexible scope introduced through the stomach, rectus, bladder, or vagina. However, available endoscopes have several limitations if used in the peritoneal cavity. The hybrid technique reported overcomes these limitations by using conventional 5-mm laparoscopic instruments through the umbilical scar and transabdominal sutures for retraction. After creating the pneumoperitoneum with a Veress needle, a 5-mm port is introduced into the umbilicus followed by a 5-mm, 30 degrees scope. A culdotomy then is performed under direct and laparoscopic views. The flexible endoscope is inserted into the pelvis through the vagina and advanced to expose the gallbladder. Three or more transabdominal sutures are placed through the gallbladder wall for retraction. Cholecystectomy then is performed using conventional 5-mm laparoscopic instruments through the 5-mm umbilical port. Finally, stay sutures are removed and the specimen is retrieved through the vagina. Six patients successfully have undergone this new procedure. In our opinion this hybrid approach increases safety, overcomes the limitation of the current instrumentation, and maintains most of the advantages of Natural Orifice Transluminal Endoscopic Surgery.
