Since the clinical phenomena presented by incomplete or partially obstructive lesions in this tube are referable, rather to the nature and location of the lesion than to obstruction, these affections will not be studied in this paper.
Complete obstruction to the passage of the contents of the intestinal canal is generally characterized clinically by the symptom-complex of an acute affection. The causative lesion, however, may be of acute (sudden) or chronic (slow) development. In accordance with the underlying clinically recognizable etiologic factor, the different varieties of acute intestinal obstruction (ileus) may be classified as (1) dynamic ileus and (2) mechanical obstruction.
