预防胰十二指肠切除术后胰瘘的临床研究

目的：改进胰肠吻合技术并探讨预防胰瘘的术式。方法：16例胰头癌根治切除术后，改进消化道重建方法，术后经胆道T管逆行造影，观察胰肠吻合肠襻的影像特征。结果：16例无胰瘘并发症。术后T管造影显示，快速注药可见胰肠吻合肠襻及吻合口显影。结论：改进胰肠吻合的缝合技巧及减轻胰肠吻合肠襻张力的术式有助于预防胰瘘。

Clinical research on preventing pancreaticojejunal anastomotic leak in pancreatoduodenectomy

Objective:To improve the technique of pancreaticojejunal anastomosis and to study the method of preventing pancreaticojejunal anastomotic leak.Methods:Sixteen patients with carcinoma of pancreatic head underwent radical resection;the methods of reconstructing digestive tract were improved.The character of the loop of pancreaticojejunal anastomosis was observed by retrograde cholangiography.Results:There was no pancreaticojejunal anastomotic leak in 16 patients.Injecting rapidly in retrograde cholangiography,there was the develop of contrast medium in the bowel loop and stoma of pancreaticojejunal anastomosis.Conclusion:Having improved the technique of pancreaticojejunoctomy and relived the tension of loop of pancreaticojejunal anastomosis may lead to preventing pancreatic fistula.
