If you had galebladder removed can one have the Lap Band surgery

You can certainly still have laparoscopic gastric banding surgery with a previous history of gallbladder surgery.  If your gallbladder was done by an open approach that can make your laparoscopic gastric banding a bit more difficult but it can still be done.  The difficulty arises from the scarring that you will have in the right upper segment of your abdomen.  Therefore inorder to perform the surgery we will need to clear the scar in that area, or use an alternative approach from the middle of your abdomen to place the band laparoscopically.   This is a technical point but from your standing it is important to understand that the operation will take longer.  Hope this information helps.

Gallbladder removal is the most common surgical procedure done, and having your gallbladder removed previously is common. The scar tissue is typically minimal, even with the "old fashioned" open type surgery. If you have a gallbladder that has stones in it, and has caused difficulties then the gallbladder can be removed at the time of lap-band surgery

Yes there is no problems to perform the band procedure after your gallbladder was removed. That will be performed laparoscopically and will take less than 1 hour.
