Can a lap band be removed and replaced with sleeve at the same time during surgery?

Hello, it is possible after clearing the needed pre operative evaluations. Such as endoscopic studies, bloodwork and evaluations from other departments to clear the paien for a Comvertion surgery, here, the doctor removes the band and do the VGS in the same operating time.

Absolutely yes!  I do this all the time.  The band can be removed and revised to any other bariatric procedure including the gastric sleeve.  Consult with an experienced bariatric surgeon to discuss your options.  

Sometimes you can - other times you are unable to do that. If the lap-band has resulted in a dilated upper pouch sometimes the surgeon will need to allow the stomach to get better and come back later to be safe.
