Laparoscopic cholecystectomy is done "retrograde"

Release Date: 2020-06-29




An animal experiment project, "Experimental Study of snake-assisted Single-cavity soft endoscope for pure NOTES retrograde cholecystectomy in a pig model", completed by Professor Liu Bingrong2, director of The First Affiliated Hospital of Zhengzhou University, was recently published in the international journal of Surgical Endoscopy.

In the evaluation of the reviewers, this research achievement has opened up a micro innovative way of endoscopic retrograde cholecystectomy.


Natural endoscopy surgery (NOTES) is a minimally invasive surgical method that USES flexible endoscopy to enter the body through the natural cavities of the mouth, esophagus, stomach, colorectal, vagina and bladder to carry out endoscopic diagnosis and treatment, which is more favored by doctors and patients than traditional laparotomy and laparoscopic surgery.

In NOTES cholecystectomy, however, abdominal adipose tissue blocks the gallbladder triangle, creating an approach "blind area" that makes it difficult to locate gallbladder ducts and arteries.

Inspired by the open surgery and the retrograde or "bottom first" approach of complex laparoscopic cholecystectomy, Liu and his team members kept innovating and finally successfully completed the complete endoscopic NOTES cholecystectomy through repeated exploration in large experimental animals.

Its specific technology route is: 15 cm away from the vaginal opening experimental animals, anterior wall with HOOK knife cut anterior wall after vaginal vault, into the abdominal cavity after the uplink find liver, gallbladder and liver visible edge is closely linked, along the connection with needle aperture after injection of saline, with the help of a HOOK knife cut along the cracks, change into IT further stripping knife the gallbladder, and the snare to pull into the abdominal cavity after, fully exposed the gallbladder, and then gradually free;

Strip along the gallbladder bed to the neck of the gallbladder, clamp both ends of the gallbladder neck with 2 hemostatic clips, then switch HOOK knife to cut off the neck of the gallbladder.

Finally, the excised gallbladder is removed via the vagina along with the snares.

The whole operation should take no more than two hours.
