Diet differences depending on type of surgery

Are there any major diet differences for those having an open RNY v/s the other types of bariatric surgery? I read about some people dumping on sugar, but somebody posted that they can eat hershey's kisses in moderation. I wondered if there was a difference in what you could tolerate depending on the type of surgery?
