Unitarity cuts of enhanced Pomeron diagrams are analyzed in the framework of the Reggeon field theory. Assuming the validity of the Abramovskii-Gribov-Kancheli cutting rules, we derive a complete set of cut nonloop enhanced graphs and observe important cancellations between certain subclasses of the latter. We demonstrate also how the present method can be generalized to take into consideration Pomeron loop contributions.
