Septa in the appendix: a previously undescribed condition
Abstract:
A previously undescribed condition of the appendix, consisting of complete and incomplete septa is reported in 25 cases. The abnormality occurred in persons younger than 30 years. In all cases the lesion was found to be associated with acute appendicitis. Possible factors discussed with respect to aetiology and pathogenesis are: a congenital abnormality similar to intestinal atresia; post-inflammatory fusion of ulcerated, swollen mucosal folds; ischaemia caused by thrombosed vessels; mucosal folding in the process of expulsion of appendiceal contents.
