You can have the gas and rumbling for a while, especially if the abdomen was involved. If Gas-X doesn't help, maybe call doctor? Gas can also be deceptively painful.

This was the sympton along with pain, that sent me to surgery, and its continuing. I'm worried a lot now

It is very frustrating when the thing you set out to get fixed doesn't go away.

various medications/anesthetic drugs used, including but not limited to isoflorane or other gas anesthetic, atropine to reduce secretions and maintain heart rate, narcotics for pain, and other anti-emetics (anti-vomiting) meds.

Check with your physician if it persists, but as I mentioned before light exercise (walking) within the range of what has been recommended by your post-surgery healthcare team can help a lot. So, too can probiotics--even high-quality active culture yogurt. Plain has more advantages because high-sugar yogurt tends to feed the bad bacteria (and yeast) already in your gut rather than the "good kind" in the culture that you'd like to preserve for gut health and improved immune function.

Hang in there. I think you will likely see steady improvement. If not, of course, have them consider other possibilities and work-ups, but the odds are on your side. Try to keep the stress in check as it is working against you.

Ty so much. So hoping this constant gas would have stopped

It might take some time for the gas they pump in to absorb and work out of your body. I had gallbladder surgery in 2018. I was able to take it easy after the surgery. The dr. prescribed an opiate, but ibuprofen and Tylenol did a better job.
Some pain after surgery is usual. If you have concerns, be sure to talk to the dr. who suggested surgery.
Hope you feel much better soon!

They removed an organ. Other stuff inside may be settling & seeking it's new level.
Plus, as someone else noted, the gasses used for laparoscopy could cause some of this.
I'd give it a full week before I got pessimistic.
