The "dent"...? Are you speaking about the top of the stomach (where leaks mostly occur), or (most likely), the lower part that attaches to the small intestine...? Sounds like she may have a stricture.
Strictures--usually at the pylorus--the junction of the stomach and first part of the small intestine (duodenum)--is usually due to too small a bougie causing the surgeon to make that area where the stomach empties into the small bowel too narrow. Sounds like they may try to dilate the narrowed junction. Strictures are usually less complicated to fix than "leaks."
Try to stay calm.
