SR Print(0) ID 1105490200 T1 Appendix T2 CURRENT Diagnosis & Treatment: Surgery, 14e YR 2015 FD 2015 PB McGraw-Hill Education PP New York, NY SN 9780071792110 LK accessmedicine.mhmedical.com/content.aspx?aid=1105490200 RD 2024/03/28 AB In infants, the appendix is a conical diverticulum at the apex of the cecum, but with differential growth and distention of the cecum, the appendix ultimately arises on the left and dorsally approximately 2.5 cm below the ileocecal valve. The taeniae of the colon converge at the base of the appendix, an arrangement that helps in locating this structure at operation. The appendix is freely mobile in the majority and is fixed retrocecally in 16% of adults.
