Sigmoid volvulus: mischief from a gravid uterus

Retroversion of Gravid Uterus

On the 20th of February last I was consulted by J. M., a married woman, 38 years of age. She had had seven living children (being delivered of twin girls on one occasion) and three miscarriages, and she calculated that she was about the middle of the fifth month of her tenth pregnancy. The catamenia last appeared in the beginning of October last year, and she first felt the movement of the chil...

Sigmoid colon volvulus in pregnancy: a case report

Background: Sigmoid volvulus is a rare complication in pregnancy. The clinical presentation is similar to that of non-pregnant volvulus, although the symptoms can be masked by the enlarged uterus and physiological changes during pregnancy and it can be challenged and delayed in diagnosis and treatment. Delay in diagnosis can also lead to ischemia, necrosis and perforation of the intestine, whic...

Classification of Sigmoid Volvulus

Management of Sigmoid Volvulus Avoiding Sigmoid Resection

Acute sigmoid volvulus is typically caused by an excessively mobile and redundant segment of colon with a stretched mesenteric pedicle. When this segment twists on its pedicle, the result can be obstruction, ischemia and perforation. A healthy, 18-year-old Caucasian woman presented to the emergency department complaining of cramping abdominal pain, distention, constipation and obstipation for t...

A biomechanical model for the gravid uterus

The biomechanics of the uterus is studied on a mathematical model based on a shell of ellipsoid of revolution. The myometrium is treated as a homogenous, isotropic and incompressible elastic material using continuum approach and large deformation theory as introduced by Fliigge and Chou [1] and Green and Adkins [2]. The governing equations which are nonlinear differential equations of boundary ...
