ABSTRACT
Seven cases of esophageal intramural pseudodiverticulosis (EIPD) are presented and compared with 46 cases previously reported. EIPD is mainly a disease of older age with a 3:2 predominance of male patients. The radiologic appearance of EIPD shows great variation in localization and severity of visible changes. Radiologic examination is far more sensitive than endoscopy in diagnosing EIPD. The most effective therapy for EIPD is dilatation of strictures, leading to amelioration or disappearance of symptoms in over 90% of cases. Visible pseudodiverticula may persist after therapy, even in symptom-free patients.

The authors propose a new model to estimate the forces of the intrinsic equilibrium of the segment. Based on the theory of the so-called transient pole, it became possible to describe the momentary movement of an angle relative to its neighbour and to define the way of the intrinsic equilibrium. This transient pole fixes the centre of rotation around which the upper angle moves relative to the lower vertebral body. Normal and pathological cases can be diagnosed at once by use of a special röntgenological appliance in connection with the statistical experience. It becomes possible to calculate the forces and movements acting on a segment.
