ABSTRACT

Objective To discuss two simulation studies on the closed and open peritoneum in abdomenal operations. Meth-ods We selected 120 domestic female rabbits from animal laboratory of Qi Qi Ha’er Medical College at random and divided them into four groups(according to whether the peritoneum was open or not,the degree of peritoneum defect at the right side of incision and the existence of peritoneum hemorrhagic focus ),with 30 cases in each group. Group Ⅰ no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision; Group Ⅱ no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision,with a hemorrhagic focus at peritoneum defect;Group Ⅲ with peritoneum suture; Group Ⅳwith dense and compact peritoneum suture.And then we analyzed postoperative peritoneum healing progress. Results Observeations of the incision infection by the naked eye were that one case was identified in group Ⅰ,Ⅲ and Ⅳ;and a significant difference of occurrence rate was identified between the fallowing groups groupⅠandⅡ(P
