A Collis gastroplasty is a
surgical procedure performed when the surgeon desires to create a
Nissen fundoplication
A Nissen fundoplication, or laparoscopic Nissen fundoplication when performed via laparoscopic surgery, is a surgical procedure to treat gastroesophageal reflux disease (GERD) and hiatal hernia. In GERD, it is usually performed when medical thera ...

into the esophagus.
In fact, gastroplasty can be used when the length of the intra-abdominal esophagus is short and for anti-reflux action such as Nissen fundoplication, it is necessary to increase the intra-abdominal length of the esophagus.
At this time, part of the upper part of the stomach is separated by a stepper, i.e. the stapler fires longitudinally along the esophagus and increases the length of the stomach inside the abdomen.
At this time, a tongue is created from the stomach that can be easily rotated on the new esophagus and all kinds of fundoplication operations such as Nissen fundoplication can be done easily.
It was devised by John Leigh Collis (1911–2003), a British cardiothoracic surgeon, in 1957.
