急性小肠出血的术中精确定位及对外科治疗的意义

目的 探讨急性小肠出血的术中精确定位方法及对外科治疗的意义.方法 回顾性分析1995年1月至2007年6月间急性小肠出血22例患者的临床资料.22例中5例行介入标记镍铂合金圈定位后手术治疗(A组);5例未行介入标记手术治疗(B组);12例行单纯介入栓塞治疗(C组).观察确诊率、复发出血率、肠管切除长度和手术时间.本组计数资料采用x2检验,计量资料以-x±s表示,采用t检验.结果 A组确诊率100%(5/5),与B组(20%,1/5)相比,差异有统计学意义(x2=6.667,P=0.024);A组肠管切除长度(12±7)am,较B组(108±23)cm短,差异有统计学意义(t=-8.574,P=0.000);A组手术时间(119±12)min较B组(218±45)min短,差异有统计学意义(t=-4.730,P=0.001);A组无复发出血,B组复发出血率为60%(3/5)(x2=4.286,P=0.083),C组复发出血率为67%(8/12),A组与C组相比,差异有统计学意义(x2=6.296,P=0.020).结论 介入标记镍铂合金圈定位法可快速准确定位出血部位,缩短手术时间;术中C型臂X线透视设备动态显像标记物,使手术避免了盲目性,提高了确诊率,降低了复发率,减少了正常肠管的切除长度.

Intraoperative accurate location and its effect on surgical treatment for acute intestinal hemorrhage

Objective To evaluate the clinical significance of intraoperative accurate localization of bleeding slte for acute intestinal hemorrhage. Method Twenty-two patients with acute intestinal hemorrhage,admitted from January 1995 to June 2007,were reviewed retrospectively.GrouD A included 5 patients who were treated with intestinal resection following intervention radiological marking.Group B included 5 patmnts who were treated by intestinal resection without intervention radiological marking.Group C included 12 patients who were treated by interventional embolization.The exact diagnostic rate,the recurrence of hemorrhage,the length of intestine removed and the operative time were calculated and analyzed respectively.Results All the cases in group A were correctly diagnosed.The diagnostic rale of group A was higher than that of group B significantly(x2=6.667,P=0.024).The average length of intestine removed in group A was(12±7)cm shorter than that in group B(108±23)cm significantly (t=-8.574,P=0.000).The procedure lasted(119±12)min in group A shorter than the(218±45)min in group B significantly(t=-4.730,P=0.001).There was no case with recurrent hemorrhage in group A,but the recurrence of hemorrhage was up to 60.0%(x2=4.286,P=0.083)in group B and 66.7%in group C(x3=6.296,P=0.020). Conclusions The treatment outcome after intestinal removal following intervention radiological marking is better than those of non-marking groups.The locating method with alloy coil made of Nickel-Platinum is rapid and accurate.C-arm X ray device helps to find the metal marker hence to give an accurate guide for bowel resection.
