Clinical, Morphological, and Immunohistochemical Justification of Surgery for Chronic Appendicitis in Children.

Chronic appendicitis (CA) is a diagnosis characterized by long-standing right lower quadrant pain. We analyzed clinical, morphological, and immunohistochemical studies of the appendix to confirm the adequacy of surgery for CA in children . We carried out comparative studies of clinical presentations and results of morphological and immunohistochemical studies of remote appendicitis in 55 children with chronic recurrent lower quadrant pain (CRLQP).
