Does the risk of recanalization increase if a person chooses an open-ended vasectomy (which closes only testicular end of the vas deferens)?

The risk of recanalization may increase if: a person chooses an open-ended vasectomy, which closes only one end of the vas deferens

Four methods of vas occlusion that appear to be consistently reliable with regard to contraceptive and occlusive effectiveness were identified: (1) MC with FI and without the use of ligatures or clips on the vas; (2) MC without FI and without the use of ligatures or clips on the vas; (3) open ended vasectomy leaving the testicular end unoccluded while using MC of the abdominal end of the vas with FI; and (4) the Marie Stopes International method of vasectomy with extended non-divisional electrocautery of the vas.
The first link does not give any sources for their claim, and the second link (a review published in 2012) mentions that the evidence is limited. I'm hoping that since 2012 the medical literature has improved on it. Does the risk of recanalization increase if a person chooses an open-ended vasectomy (which closes only one end, namely the testicular end, of the vas deferens)?
