Large Anastomosis
It could explain being able to eat more and being hungry but it wouldn't explain weight gain with compliance. You may have a metabolic issue. If you are considering revisions I would look into a revision to a DS. It is a complicated revision and it isn't done by a lot of surgeons. You can check out the revision board and also dsfacts.com.

No, it wouldn't make you gain weight if you're eating small meals and things low in calories. The reason it sometimes leads to weight gain is because it causes food to leave the pouch quickly so you get hungry again fast and then overeat. If you aren't eating too much, a large stoma would not cause weight gain.

What Kelly said. The only thing an enlarged stoma changes is how fast the food leaves your pouch. If you are still watching your portion sizes and making healthy food choices, it would not lead to weight gain. Also, are you drinking when you eat? That can also lead to eating too much.
How far out are you? If you are at the point where you have lost most of the caloric malabsorption, you may have to adjust your food intake to accommodate for this. (Edited: I see that you are 4 years out... so you should already have lost your caloric malabsorption... but how long has the weight gain been going on? If it has been going on slowly for 2 years, this might still be a contributing factor.)
There are a couple of procedures that can reduce the stoma, but they all have a very low success rate so most insurance won't cover them.
