n-dimensional lattice paths which do not touch the hyperplanes x(i)-x(i+1)=-1, i=1,2,...,(n-1) and x(n)-x(1)=-1-K are enumerated by MacMahon's major index and variations of the major index. A formula involving determinants is obtained. For n=2 we also present a formula for counting these lattice paths simultaneously by major and descents.
