We report a preliminary experience concerning the postoperative assessment of three patients who underwent gracilis neosphincter operation for severe fecal incontinence and were studied by computed tomography and anal endosonography soon after gracilis transposition and later after 6-8 weeks of neuromuscular training. Morphologic assessment was correlated with physiologic testing (manometry). Continence was satisfactorily improved in all patients. Both imaging techniques demonstrated the anatomy of the transposed muscle. Computed tomography also assessed lead placement onto the gracilis nerve root and the completeness of muscle transposition around the anal canal. Anal endosonography provided a more accurate assessment of the relation between the neosphincter and residual external sphincter.

UI MeSH Term Description Entries
D008297 Male Males
D008365 Manometry Measurement of the pressure or tension of liquids or gases with a manometer. Tonometry,Manometries
D009470 Muscle Spindles Skeletal muscle structures that function as the MECHANORECEPTORS responsible for the stretch or myotactic reflex (REFLEX, STRETCH). They are composed of a bundle of encapsulated SKELETAL MUSCLE FIBERS, i.e., the intrafusal fibers (nuclear bag 1 fibers, nuclear bag 2 fibers, and nuclear chain fibers) innervated by SENSORY NEURONS.

D011312 Pressure A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Pressures
D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations
