ABSTRACT
From December 2011 to August 2017,56 patients with acute abdomen surgery were treated in Affiliated Zhongshan Hospital of Dalian University.The anatomical structure of ileocecal Treves folds was observed during operation,and 15 samples of Treves folds were taken for histological examination.The mean length of the fold was (5.56±0.18)cm for males and (5.22±0.05)cm for female,the width was (1.82± 0.04) cm for males and (1.78 ± 0.06) cm for females;the thickness was (0.18 ± 0.02) cm.HE and verhoeff staining showed that Treves fold was mainly composed of elastic fiber,collagen fiber and smooth muscle with abundant blood supply.Thirty patients were repaired with their own Treves folds,including the fixation with overlay suture to the stump of appendectomy in 26 cases,repairing for perforation of colonic diverticulum in 3 case,and repairing for perforation of colonic diverticulum in 1 case.There were no complications such as fecal fistula,intestinal obstruction and intussusception after operation.The Treves fold has a constant location,which can be used as a clear sign of ileal terminal.It has abundant blood supply,and is suitable for the repair and reconstruction in ileocecal operation.
