COLICS THROUGH INTESTINAL OCCLUSION. 169 



between aneurism and colics. Anacker ^ and Ziirn^ admit the possi- 

 bility of thrombotic or embolic colics, but they disagree with Bol- 

 linger in reference to their frequency. Roll,^ on the contrary, would 

 like to extend this pathogeny of colic to all cases where abdominal 

 pains appear suddenly and without precise apparent cause, making, 

 however, certain restrictions, and in this he is supported by the 

 Munich professor. In our opinion the existence of thrombo- 

 embolic colic cannot be the subject of doubt ; we even believe these 

 accidents to be quite frequent, but we think that Bollinger has 

 gone too far in incriminatiug the thrombi of intestinal arteries as 

 the cause of half the fatal cases of colic, and in considering as 

 being of a thrombo-embolic nature any colic appearing suddenly 

 and without appreciable cause. 



Colics through Intestinal Occlusion. 



Under this title we classify colics due to any kind of obstacle 

 hindering the circulation of intestinal matters. Looking at the 

 causes producing them, we can admit the following varieties : 



1. Colics due to the accumulation and hardening of alimentary 

 or excremeutitious matter in the caecum, the colon, and the rectum 

 (coprostasis) ; 



2. Colics provoked by gastric or intestinal calculi ; 



3. Colics determined by changes of relation of the intestine ; 



4. Colics of invagination ; 



5. Colics produced by neoformations which diminish the calibre 

 of the intestine ; 



6. Colics due to constriction of the intestine ; 



7. Colics provoked by the dilatation or paralysis of the intestine. 



1. COLICS DUE TO THE ACCUMULATION AND HARDENING OF 

 ALIMENTARY OR EXCREMENTITIOUS MATTER IN THE CJECUM, 

 THE COLON, AND THE RECTUM (cOPROSTASIS) : COLICS OF 

 CONSTIPATION. 



Etiology. The causes of these colics have been mentioned in 

 the article on General Colics. We must mainly look for them in 

 the diet — for instance, in cases of ingestion of a large quantity of
