INTESTINAL STRANGULATIONS . BY ADVENTITIOUS 



BANDS. 



Result of circumscribed peritonitis. Extends from one part of abdominal 

 wall to another, around or between intestines, on omentum, or adhesion of 

 omentum to inguinal ring. In cattle tubercular products strangulate bowels. 

 Symptoms : the colic of obstruction, rectal exploration. Treatment : lapar- 

 otomy, removal of constricting band. 



Adventitious fibrous bands in the abdomen are the result of a 

 pre-existing peritonitis of a circumscribed area. The fibrinous 

 exudate thrown out on the parietal peritoneum is detached in its 

 median part but remains adherent at the ends, and when organized 

 into tense resistant white fibrous ti.ssue remains as a trap to en- 

 tangle and strangulate the intestinal folds. In other cases they 

 form on or between intestines or other viscera which are for the 

 moment torpid and inactive, and contracting as they become 

 organized, they bind these together and hamper their movements, 

 and endanger the integrity of all movable viscera in the vicinity. 

 Again they form on the omentum and threaten the integrity of 

 the bowels by strangulation. The omentum protruding at castra- 

 tion becomes adherent to the inguinal ring and forms a dangerous 

 band. 



In cattle the growth of peritoneal tubercle often binds the small 

 intestines together in an inextricable tangle leading to consider- 

 able compression, and obstruction without a complete stenosis. 



Symptoms. These vary with the organ constricted, but they 

 are usually those of a more or less perfect obstruction of some 

 portion of the intestine small or large, which has pas.sed over or 

 under the constricting band and fails to return, often undergoing 

 a torsion which renders its imprisonment still more .secure. The 

 author has found the double colon fatally constricted in this way, 

 and Leblanc furnishes a similar case. Cases are on record of the 

 binding of the duodenum to the right lobe of the liver by a strong 

 fibrous band, of the binding of the double colon to the right flank 

 and in another case to the floor of the abdomen, and of the ileum 

 to the meso-rectum and in another ca.se to the left flank. These 

 give rise sooner or later to obstruction of these viscera or, to in-
