The epidemic of morbid obesity has increased bariatric procedures performed.
Trend analyses provide important information that may impact individual practices.
Dr Mohammad Jamal and colleagues from Iowa evaluated bariatric surgery trends in the US.
Patient data from 137 surgeons were examined from 1987 to 2004 of 41,860 patients using Cochran-Armitage Trend test and Generalized Linear Model.
The research team found that over an 18-year period, surgeon preference for combined restrictive-malabsorptive procedures increased from 33% to 94%.
However, the team noted that simple gastric restriction decreased correspondingly.
|Cases per surgeon increased by 71%|
|American Journal of Surgery|
Surgeons per worksite doubled and cases per surgeon increased 71%.
The researchers observed that laparoscopic procedures increased to 24%.
The percentage of males, mean operative age, and initial body mass index increased significantly.
The research team noted that postoperative hospital stay decreased from 5 to 4 days.
The most common procedure in 2004 was Roux-en-Y gastric bypass in 59% of patients.
Dr Jamal's team concludes, “Bariatric surgery patients are now older and heavier, length of stay is shorter, and the laparoscopic approach is more frequent.”
“From 1987 to 2004, the general trend shows a clear preference for combined restrictive-malabsorptive operations.”
