Chronic duodenal ileus or obstruction may be divided into several types. It may be idiopathic, or it may result from some abnormality or pathologic condition, including postoperative complications. Idiopathic ileus may be (1) adynamic or paralytic; (2) dynamic, due to excessive muscle contraction, or (3) mechanical.
Clinically, the course may be persistent, intermittent or remittent.
The location of the obstruction may be in any portion of the duodenum. In this study, however, the nonparalytic type of idiopathic ileus is chiefly considered, with the obstruction at the terminal duodenum.
Numerous theories and predisposing factors have been advanced for this condition, with little supporting evidence. However, no reference has been noted in the literature to the association with hyperthyroidism.
The anatomic postmortem observations in one case add unusual interest.
