If you ask me the work of Shintaro Kago follows an identical pattern; somewhat stylish yet profoundly revolting artwork combined with surreal plotlines and bland characters.
If you for some reason liked Abstraction (from Kasutoro Shiki), then make sure to check out Fetus Collection (from Kijin Gahou), or vice versa. They're both utterly tasteless stories with impossibly crude characters and explicit depictions of love and sex.
Genesis (from Kasutoro Shiki) and Fetus Collection (from Kijin Gahou) are Shintaro Kago manga for people who find things like religion and the abortion morality debate laughable, and appreciate the bizarre and grotesque.
Two short absurdist gag manga that take an experimental approach to presentation. Both subvert manga's traditional paneling (i.e.- panels become 3-D, or branch out non-linearly), and the actual story often takes a backseat to this experimentation.
