title: [Variants of the suspensory muscle of the duodenum (Treitz's ligament) and the anatomical basis for its effective dissection in duodenal stasis].
abstract: Depending on peculiarities of the duodenum fixation to the posterior abdominal wall, normal (normoduodenum), dolichoduodenum and duodenoptosis variants are distinguished. The m. suspensoris duodeni (ligament of Treits) in each variant has its peculiarities. At the normoduodenum and dolichoduodenum, the ligament of Treitz contains a considerable amount of striated muscle tissue. At the duodenoptosis--it consists of a loose fibrous connective tissue with single smooth (non-striated) muscle fibers. As demonstrate anatomical experiments for dissection of the normal ligament of Treitz and of its two variants, dissection of the ligament of Treitz at duodenoptosis eliminates essential anatomical prerequisites of duodenostasis.
