The study aims to demonstrate the presence of a fibrous or fibromuscular ring structure within the wall of the sacs of @entity169 in @entity1 and its importance in the development of incarceration as a direct cause of this complication. A case series study of 784 @entity1 with unilateral inguinal @entity547 operated on over a period of 9 years (1992-2000) in two teaching hospitals (Mosul, Iraq). All underwent herniotomy. The sacs were examined for the presence of a ring structure, and the excised sacs containing the rings were studied histopathologically. The presence of the @entity547 ( @entity547 ) and its significance in the causation of incarceration was studied. Out of 784 cases, 660 were elective and 124 incarcerated @entity547 . In 56 sacs the @entity547 ( @entity547 ) was present - 36 rings in the elective and 20 rings in the sacs of incarcerated @entity547 . The histopathology of the @entity547 was fibrous or fibromuscular tissue. This ring has its significance in the development of incarceration. @entity547 with the @entity547 are three times more liable to incarceration than those without the ring. Incarcerations of @entity169 in @entity1 are usually caused by the inguinal rings. Another cause for incarceration being studied is a fibrous or fibromuscular ring structure identified within the wall of the hernial sac, causing the incarceration in 5.6% of elective (nonincarcerated) @entity547 and 16% of @entity547 @entity1 . @entity1 with these hernia sac rings are three times more liable to incarceration than others.

A constricting ring structure within the wall of the XXXX in @entity1 and @entity1 and its role in the occurrence of incarceration.
