摘要
目的 通过大网膜包裹胰腺后缝合胰腺残端术式的动物模型寻找一种能有效降低术后胰漏率且简单实用的新方法.方法 行胰腺远端切除术后,将50只新西兰兔用随机数字表法分为对照组(25只)和实验组(25只)2组,对照组为单纯应用5-0 Prolene线U型锁边缝合胰腺残端;实验组为先将大网膜包裹胰腺一圈后,使其紧贴于胰腺表面,再缝合胰腺残端.测量和观察术后第1、3、5、7天血淀粉酶、白细胞计数、C反应蛋白、体质量、术中失血量、嗜睡和厌食发生率.2周后将动物处死检查,胰腺残端行石蜡切片病理学实验组检查.结果 实验组兔子的胰漏率8.0%(2/25)明显比对照组低36.0%(9/25)(P<0.05);实验组术后第1、3、5、7天淀粉酶值分别为(175 ±30) U/L、(150±31) U/L、(142±26) U/L、(141±28) U/L,对照组术后第1、3、5、7天淀粉酶值分别为(174 ±30)U/L、(151±31) U/L、(141±26)U/L、(142±28)U/L,差异均无统计学意义(均P>0.05).实验组和对照组术后第1、3、5、7天白细胞计数分别为(10.1±2.2)×109/L、(8.3±2.5)×109/L、(7.9±2.3)×109/L、(7.5±2.6)×109/L和(10.2±2.2)×109/L、(8.4±2.5)×109/L、(7.8 ±2.3)×109/L、(7.4±2.6)×109/L;,实验组和对照组术后第1、3、5、7C反应蛋白数值分别为(10.1±1.6) mg/L、(26.3 ± 5.5) mg/L、(18.6±1.2) mg/L、(16.4±1.2)mg/L和(10.3±1.6)mg/L、(26.5±5.5)mg/L、(18.8±1.2)mg/L、(16.6±1.2) mg/L,差异均无统计学意义.实验组兔子的手术时间(61±11)min明显比对照组(53±11)min长(P<0.05),但试验组和对照组兔子的体质量、术中出血量、嗜睡和厌食发生率分别为(2.76±0.31) kg、(6.00±1.00) mL、4.0% (4/25) 、8.0%(2/25)和(2.82±0.22)kg、(5.86±0.90)ml、16.0%(4/25)、24.0%(6/25),差异均无统计学意义(均P>0.05).病理学显示实验组
Objective To analyze animal models of pancreas stump surgical suture after omental wrapping of the pancreas.Methods After distal pancreatic resection,50 rabbits were randomly divided into two groups:the control group underwent the simple use of 5-0 Prolene suture line U-catcher pancreatic stump; the experimental group,after the first lap omental wrapping of the pancreas close to the surface of the pancreas,was stumped and then sutured.After 1,3,5,7 days peritoneal drainage,amylase values,C-reactionprotein values,weight,blood loss,lethargy and anorexia incidences were measured.After two weeks,the animals were sacrificed and examined for pancreatic stump line paraffin pathology.Results The leak rate of pancreas was 8.0% (2/25),significantly lower than 36.0% (9/25) (P 〈 0.05) ; amylase values in both groups were (175 ± 30) U/L,(150 ± 31) U/L,(142± 26) U/L,(141 ± 28) U/Land (174±30)U/L,(151±31)U/L,(141 ±26)U/L,(141±28)U/L and the difference was not statistically significant.White blood cell counts was (10.1 ± 2.2) × 109/L vs (8.3±2.5) ×109/L,(7.9±2.3) ×109/L vs (7.5±2.6) ×109/L and (10.2 ± 2.2) ×109/L vs (8.4±2.5) × 109/L,(7.8 ± 2.3) × 109/L vs (7.4 ± 2.6) × 109/L.C-reactive protein value was (10.1 ± 1.6) mg/L vs (26.3±5.5) mg/L,(18.6 ± 1.2) mg/Lvs (16.4 ± 1.2) mg/Land (10.3 ± 1.6) mg/Lvs (26.5 ± 5.5) mg/L,(18.8 ± 1.2) mg/L vs (16.6 ± 1.2) mg/L; the difference was not statistically significant.In experimental group,operative time (61 ± 11) min was significantly longer than that in the control group (53 ± 11)min longer (P 〈 0.05),but in both groups,weight,blood loss,lethargy and anorexia incidence showed no differences [(2.76 ± 0.31) kg,(6.00 ±1.00)ml,4.0%(4/25),8.0%(2/25),(2.82 ±0.22)kg,(5.86±0.90)ml,16.0% (4/25),24.0% (6/25)](all P 〉 0.05).Pathology showed that in the experimental group,pancreatic stump edge had thick
