Caecum (typhlon) with ascending colon and part of transverse colon considered as a chamber: Superior colic ventriculus (holotyphlon)

Summary

Having shown, in man, and in comparative animal types, the area which may be called that of the Superior Colic Ventriculus (Holotyphlon) it is evident that the Physiology and the Pathology of this portion of the alimentary canal is a very important matter ; (to surgeons, dealing with the “acute abdomen,” less immediate interest in previous conditions is possible).

A better handling of the colon, however, before acute or chronic lesion develop may become possible, especially if we are directed to the area as a definite region of slower progress. The study of faeces as a routine affair is still not common. Also, in acute respiratory conditions the colon demands attention. (12)

Disturbances lower in the alimentary tract cause reflex changes higher (Edward Martin). Constipation, obstipation and various excretory functions are probably concerned with difficulties in this region. Those who have seen animals (horses or oxen) became paralyzed from improper feeding, know as well as all veterinarians do, what this nerve collapse implies. In man, from childhood to old age, extreme conditions develop. Because a classical tradition denominates the large intestine (colon) as a simple entity, we have omitted to discriminate among its actual physiologic subdivisions, as we might. (7)

This note, resulting from over a thousand careful dissections, could be followed by considerable detail, known it is true to all of us, but as yet quite in its infancy as to medical application ; in conditions of colon complicating other ailments, especially.
