How common is nissen fundplication surgery? is it true that one in three surgery in western country is the nissen ?

No, not common: Nissen fundoplication is an anti-reflux procedure for symptomatic and poorly responsive gastroesophageal reflux (gerd). With the use of more potent antacids, such as proton pump inhibitors, the incidence of anti-reflux procedures is actually declining. The peak use was about 32, 000 in the us done in 1999 but down to 24, 000 by 2003. In contrast, over 600, 000 cholecystectomies are done each year.
