[Calcified appendiceal calculi in children (author's transl)].

: Authors present, a series of 73 infantile appendicular interventions, the high incidence of coproliths found in the appendix lumen (30.13%) which contrasts with the number presented by other authors which oscillate between 0.64 and 15%. The radiologic study of the extirpated appendix shows coproliths which has not been visualized in the preintervention-radiologic exploration. Due to this, authors consider convenient the study of the extirpated piece in order to the exact evaluation of the number of coproliths. Microscopic analysis and infrared spectrophotometry show the existence in the composition of the coproliths abundant in-organic material as well as organic acids and hydrocarbons.
