Your daughter had laparoscopic gall bladder surgery presumably for gall stones 9 months ago. It appears that she had injury to the bile duct resulting in bile leak. This subsequently required open tube drainage of the bile. If the drainage tube has been removed and she is not running a fever nor jaundiced, then probably things will settle down.
She has put on 60 lbs after the operation. Massive weight gain is never normal and could be due to a sedentary life style. Vomiting can occur after alcohol ingestion. However, she may require an upper gastro-intestinal endoscopy if vomiting persists.
She may also have an abdominal ultrasound to rule out intra-abdominal collections of bile.
