Morphometric variants of the cecal appendix in a living person

Abstract

Introduction: the anthropometry and location of the cecal appendix are inconstant parameters in the human being. The accumulated knowledge is scarce and very limited, mostly coming from studies in cadavers. The objective of the research was determining the biometrical characteristics and anatomical position of the cecal appendix in living persons.
Method: we carried out a prospective, descriptive, observational study, in an universe of 236 surgically treated patients, with a diagnostic of acute appendicitis in the Teaching Surgical Clinical Hospital Celia Sanchez Manduley, in Manzanillo, Granma. The approaching ways were infra umbilical right paramedical laparotomies (58,47 %) and McBurney's laparotomies (41,53 %). In the course of the laparotomy we observed the cecum and the appendixes, carrying out the ectomy by usual technique, half centimeter before its linking point with the cecum, measuring it in an extracorporeal form.
Results: the cecum was located in the right iliac fossa in 184 patients (77,97 %). The appendix was implanted behind the ileo-cecal valve in 239 cases (90,26 %) with a 9,31 cm ± 3,37 average longitude. The most frequent location was the meso-celiac one (40,25 %). The meso-appendix was triangular in 161 cases (68,22 %) and inserted in the medial third in 75,84 %. The appendix irrigation was more frequent through 3 arterial branches (77,97 %).
