IN THIS article, based on the observations that I have been able to make on the 50 patients with strangulated hernia that came under my care during the past few years, an attempt is made to describe the morbid anatomic evolution of a strangulated hernia. Of these 50 cases, 12 cases are illustrated, as each one of these depicts a phenomenon of certain pathologic significance. An analysis of the important findings, not involving biochemical or bacteriologic investigations, is also included in the article.
The anatomic changes that are brought about as a result of the constriction which gradually leads on to strangulation affect (1) the mesentery, (2) the blood vessels in the mesentery and in the bowel wall and (3) the wall of the intestine itself.
From the observations based on the changes that take place in these three fundamental regions, an attempt is made to illustrate the morbid anatomic
