Adherence
Percutaneous CT-guided cryovagotomy reduces hunger and caloric intake, leading to statistically significant weight loss and BMI reduction in patients with Class I or II obesity over 6 months.
This procedure targets the vagus nerve to reduce hunger signals. In a small pilot study, it led to an average weight loss of about 5 kg over 6 months in obese patients, largely by reducing their daily calorie intake by about 610 calories. It is not a magic bullet but a tool to help manage appetite.
LimitedSupportsLOW confidence
Ninety-five percent of patients reported decreased appetite following the procedure, and reductions in mean absolute weight and BMI were observed at all time points. ... mean caloric intake decreased over the same period.
Why this rating
Pilot trial, single-arm, open-label, small sample size (n=20), short duration (6 months), no control group.
