Some Special Master's Programs have linkages in which they have spots reserved for people who do well in their porgram... but doing well is not the same as merely completing the program. The closest thing I know of to what you've described is Ohio State's MEDPATH- and that's for URMs/disadvantaged background only. Also, you have to have applied to Ohio State once, not gotten in, and then be recommended MEDPATH.
Also, the MCAT must always been taken for linkage programs- at least, as far as I know.
Bottom line: there are very, very few back entrances to med school, anymore.
