This video demonstrate Laparoscopic Fundoplication Surgery for GERD. A Nissen fundoplication, or laparoscopic Nissen fundoplication when performed via laparoscopic surgery, is a surgical procedure to treat gastroesophageal reflux disease and hiatal hernia. The fundoplication operation is usually carried out using keyhole surgery (laparoscopy). The surgeon uses a telescope, with a miniature video camera mounted on it, inserted through a small incision (cut) to see inside the abdomen. Carbon dioxide gas is used to inflate the abdomen to create space in which the surgeon can operate using specialised instruments that are also passed through other smaller incisions (cuts) in the abdomen. The operation itself has two parts. Firstly the surgeon will examine the diaphragm to check the size of the opening around the oesophagus. If it too loose, the surgeon will tighten this. The second part of the operation involves wrapping the upper part of the stomach (fundus) around the base of the oesophagus and loosely stitching it in place. This tightens the sphincter enough to reduce reflux but not so tight as to affect swallowing.
