Fecaloma of the sigmoid flexure

Diseases of the Colon & Rectum, 1966
Fecaloma of the distal portion of the colon occurs rarely, but it should be considered in the differential diagnosis of any polypoid type of lesion. Often the diagnosis can be made from the clinical and radiologic features. In the beginning, therapy should be conservative, but surgical removal may be required.

Sinc flexure hinges

Review of Scientific Instruments, 2023
This paper proposes a new type of flexure hinge: the sinc flexure hinge. A theoretical compliance and precision factor model of the sinc flexure hinge is developed based on the transfer matrix method. The finite element simulation is carried out using ANSYS Workbench. The error between the modeling and simulation results obtained is less than 7.0%. The

Fistulas of the sigmoid flexure

Diseases of the Colon & Rectum, 1961
Records of a series of 28 patients with sigmoidal fistulas have been reviewed. Our discussion of the incidence and pathogenesis of sigmoidal fistulas is based on a review of the literature and a study of a collected series of cases. The value of various diagnostic features (symptomatology, physical examination, sigmoidoscopy, roentgenography, urologic ...
