Aralysis of 355 patients with non-suturing peritoneum in preventing purulent infection of incisional wound of appendicitis

Abstract

Objective To explore the effect of mon-suturing peritoneum in perforating purulent infection of incisional wound of appendicitis. Methods 907 patients suffered purulent perforating and gangrenous appendicitis were divided randomly into two groups:the non-suturing group of 355 patients and the control group of 552 patients.Of the non-suturing group,peritoneum was not sutured when his/her abdominal cavity was closed.It was just on the contrary to the control group.Then examined whether eoncotic rythrogenic or tender incision occurred,or whether purulent secretion flowed outside from the operative incision.These items below were also been recorded carefully:the average number of days when the temperature was abnormal,the grades of healing of incision and the average hospital stay. Results In the non-suturing group,21(5.9%)patients suffered postoperative infection,the number of days of abnormal temperature was(3.8 ± 1)d on average,and the average hospital stay was(7.5 ± 1)d;in the control group,119(21.6%)patients suffered postoperative infection,the number of days of abnormal temperature was(4.3 ± 1)d on average,and the average hospital stay was(12.9 ± 1)d.First rate healing of incision in the non-suturing group was far higher than that in the control group(P＜0.05). Conclusion Non-suturing peritoneum could help internal drainage peritoneum,which was an efficient way to guard against the postoperative infection.And non-suturing was also of great significance to reduce the average number of days of abnormal temperature and hospital stay.Meanwhile,the probability of ankylenteron and incisional hernia was not increased.
