We are so fortunate that endoscopic surgery was developed. Many surgeries for exploration and repair are now done easily and with less risk than when these procedures had to be performed with regular surgery that was invasive to the body.
When someone has a problem with biliary sphincterotomy, a surgeon can use endoscopic surgery. A few small cuts are needed so the surgeon can see through the camera and use small instruments to take out the biliary blockage, is a whole lot better than full fledged surgery. And the recovery time is much shorter. Hats off to the medical researchers!
