[Effectiveness and safety of intragastric balloon for treatment of morbid obesity].
OBJECTIVE
To evaluate the effectiveness and safety of intragastric balloon (IGB) for the treatment of obese Chinese.


METHODS
IGB was placed into the stomachs of 48 Chinese patients in Hong Kong, 13 males and 35 females; aged 39 +/- 9 (18 - 65), with the mean baseline body weight (BW) of 106 +/- 26 kg and mean body mass index (BMI) of (40 +/- 9) kg/m(2), 34 (70.8%) with coexistent obesity-related morbidities, who failed to respond to other weight reducing treatment, via routine gastroscopy under intravenous conscious sedation. Restricted balanced diet with 1200 kcal/day and exercise of 150 minutes/week were prescribed after the balloon placement. The IGB was removed endoscopically after at most 180 days. Follow-up was conducted once a week during the first month and then once a month.


RESULTS
The median hospital stay and treatment duration were 1 (IQR 1:2.25) day and 174 (IQR 166:181) days respectively. The BW, BMI, and waist circumference were significantly decreased after the IGB placement (all P < 0.01) with the mean BW loss of (13 +/- 7) kg, mean BMI loss of (5 +/- 3) kg/m(2), mean excessive body weight loss of (45 +/- 36)%, and mean waist circumference loss of (12 +/- 8) cm. 66.7% of the patients were satisfied with the treatment. No serious complication related to IGB was noted.


CONCLUSIONS
IGB is a safe and effective device that achieves moderate weight loss in obese Chinese.
