Many Smokers Who Quit Before Gastric Bypass Surgery Relapse
61.7 percent of those who smoked one year preop smoke at seven years postop
MONDAY, Feb. 24, 2020 (HealthDay News) -- Although most adults who smoke prior to Roux-en-Y gastric bypass (RYGB) quit before surgery, the rate of relapse is high, according to a study published online Feb. 20 in the Annals of Surgery.
Wendy C. King, Ph.D., from the University of Pittsburgh, and colleagues followed 1,770 adults undergoing RYGB between 2006 and 2009 for up to seven years to assess smoking history and change in smoking behavior. Participants self-reported smoking history presurgery and current smoking behavior annually.
The researchers found that 45.2 percent of participants reported a presurgery history of smoking. There was a decrease in the modeled prevalence of current smoking, from 13.7 percent in the year before surgery to 2.2 percent at surgery, followed by an increase to 9.6 and 14 percent at one and seven years postsurgery, respectively. The mean packs/day was 0.60, 0.70, and 0.77 at surgery, one year postsurgery, and seven years postsurgery, respectively. At seven years, smoking was reported by 61.7, 12.3, and 3.8 percent of participants who smoked one year presurgery, those who formerly smoked but quit more than one year presurgery, and those who reported no smoking history, respectively.
"Smoking cessation prior to surgery is strongly recommended to reduce surgical complications," King said in a statement. "But there isn't the same emphasis on maintaining cessation after surgery. Our findings show that there is a need for ongoing support in order to reduce and quickly respond to relapses."
