I am not aware of a specific connection between gall bladder surgery and rapid gastric emptying, however that doesn't mean that they cannot be connected.
Sphincter of Oddi (SO) dysfunction is an uncommon side effect following a gall bladder operation. A SO manometry can be performed to confirm the diagnosis, and if present, a referral to a surgeon can be considered to discuss whether a sphincterotomy can be performed.
A more investigational option would be injection of Botulinum toxin into the Sphincter of Oddi.
Regarding the rapid gastric emptying, you can consider an upper endoscopy to see if the anatomy of the upper GI tract is causing your symptoms.
These options can be discussed with your personal physician.
