ABSTRACT
Objective To investigate the value of ultrasound locates the appendectomy and guide appendec -tomy incision in small incision appendectomy .Methods According to the digital table ,80 patients with acute appen-dicitis diagnosed by B ultrasound examination , were randomly divided into the observation group , and the control group.Each of the group has 40 cases and use small incision appendectomy .In the observation group , mark corre-sponding appendix root in the abdominal wall surface when use B ultrasound examination ,and mark again in anesthe-sia before surgery.Design of a 2~2.5cm minimal incision according to appendix after anesthesia marker ,distance measurement before and after .The control group did not use B ultrasound localization ,minimal incision by McBurney point or near tenderness point .Between the two groups in operation time ,bleeding volume ,postoperative exhaust time , hospitalization time,complications.Results Ultrasound before and after positioning distance was (1.9 ±0.6)cm,and the preoperative immediate ultrasound localization of appendix and intraoperative exploration results ,and preoperative ultrasound localization in observation group ,the average operation time was better than no ultrasound localization of group(P<0.05).The amount of bleeding volume,postoperative exhaust time,hospitalization time,complications had no obvious difference .Conclusion Preoperative immediate ultrasound can more accurately reflect the position of ap-pendix ,favorable operation in small incision appendectomy is quickly ,shorten the operation time .
