Cecal changes following appendectomy.

The appearance of the cecum was followed from two days to 18 months after appendectomy in a series of 12 patients. The changes were often discrete and well defined. The typical localized deformation of the medial aspect of the cecum due to the invaginated appendiceal stump disappeared in half of the patients while its size was not reduced in the other half of the patients. The localized deformation was rather constant in size and measured approximately 2 X 2 cm.
