胰腺手术(包括胰十二指肠切除、胰体尾切除等)后使用奥曲肽是否能够降低腹腔并发症的发生目前仍有一定的争议。本文通过单盲随机对照方法,选择1 993~1 998年多中心2 30例行胰十二指肠切除、胰体尾切除及其扩大手术病例作为研究对象。原发病包括胰腺、壶腹部恶性肿瘤和胰腺、十二指肠良性肿瘤及慢性胰腺炎等。根据术后是否使用奥曲肽将所有病例分为奥曲肽组1 2 2例和对照组(不使用奥曲肽) 1 0 8例,两组患者在性别、年龄、原发病、手术方式等临床资料方面均无统计学差异。奥曲肽使用一般是术后连续8天以上,每天3次,每次1 0 0μg。统计的腹腔… 相似文献

奥曲肽对大鼠胰腺移植缺血再灌注损伤的保护机制 总被引:6,自引:3,他引:3
目的 探讨奥曲肽在胰腺移植缺血再灌注损伤中的作用以及可能机制。方法 应用大鼠全胰十二指肠同种异体移植动物模型,监测再灌注3、6 h血清中一氧化氮(NO)水平和超氧化物歧化酶(SOD)活性的变化,同时对移植胰进行组织学观察和诱导性一氧化氮合酶(iNOS)的免疫组织化学分析,以及应用奥曲肽和硝酸甘油(NTG)后上述指标的变化。结果 再灌注3、6 h血清NO水平、SOD活性分别为(77.13±5.29)、(103.92±11.17)μmol/L和(64.46±7.03)、(56.54±7.82)Nu/ml,与同时点假移植组差异有显著性(P均<0.01),且两指标变化呈显著负相关。应用奥曲肽后能显著降低NO水平,提高SOD活性接近至假移植组水平,与移植组相比差异有显著性(P均<0.01),并明显改善移植组织病变和降低iNOS表达强度。加用NTG后,又能在奥曲肽组基础上部分扭转上述变化,但这种现象仅在再灌注3 h时见到。结论 奥曲肽能显著下调移植胰iNOS的表达,降低血清NO水平并提高SOD活力,从而干扰NO/cGMP途径,减轻组织炎症反应,对再灌注组织起到保护作用。 相似文献

Effect of octreotide acetate on pancreatic exocrine function 总被引:3,自引:0,他引:3
S T Williams E A Woltering T M O'Dorisio W S Fletcher 《American journal of surgery》1989,157(5):459-462
Somatostatin and its analogs have been shown to inhibit both pancreatic endocrine and exocrine function. We hypothesized that octreotide acetate (Sandostatin), a somatostatin analog, decreases the pancreatic flow rate through a peptide-mediated mechanism and alters pancreatic fluid composition by inhibiting carbonic anhydrase action and circulating peptide levels. To test this hypothesis, we collected pancreatic fluid from six patients (four with pancreatic fistulas and two with pancreatic drains after pancreatic resection). Pancreatic fluid volume and chloride, sodium, potassium, amylase, lipase, and bicarbonate levels were measured before and after octreotide acetate therapy. Octreotide acetate reduced pancreatic fluid output by a mean of 75 percent (p less than 0.05), increased chloride concentration by 21 percent (p less than 0.05), and reduced bicarbonate content by 45 percent (p less than 0.05). Sodium levels were unchanged, but the potassium concentration was increased by 14 percent (p less than 0.05). Total amylase and lipase production per 24 hours was decreased by 63 percent and 27 percent, respectively (differences not significant). Somatostatin may be useful in the treatment of established pancreatic fistulas and may be a useful prophylactic tool to prevent postoperative fistula formation. 相似文献

Effects of octreotide acetate on intractable chylothorax after surgery for congenital heart diseases
Kaneko M Hiramatsu T Nishimura Y Iwahashi M Komori S Shibata M Yuzaki M Okamura Y Suzuki H Takeuchi T Shibuta S 《Kyobu geka. The Japanese journal of thoracic surgery》2006,59(7):561-564
We experienced 2 infants in whom octreotide acetate was effective on intractable chylothorax after surgery for congenital heart diseases. They were 8- and 5-month-old. They were diagnosed as having corrected transposition of the great arteries (TGA) and tetralogy of Fallot respectively, and underwent bidirectional Glenn anastomosis and right modified Blalock Taussig shunt. Chylothorax was revealed on the 11th and the 1st postoperative day, and was not improved by any conventional therapy in either case. Then octreotide acetate was infused continuously with 0.1-0.6 micorg/kg/hour for 24 and 7 days. Chylothorax disappeared completely without any complications such as disturbance of blood sugar level or growth retardation. Octreotide acetate was effective and safe even in infants in intractable chylothorax after surgery for congenital heart diseases, as long as used for short period. 相似文献

Objective
To assess the effectiveness of octreotide in preventing postoperative pancreatic fistula. Pancreatic fistula is one of the most common complications after elective pancreatic surgery. Several clinical trials have evaluated the use of octreotide to prevent the development of pancreatic fistula after pancreatic surgery with conflicting recommendations.Methods
We undertook a meta-analysis of 7 identified randomized controlled trials, reporting comparisons between octreotide and a control. The primary outcome was the incidence of postoperative pancreatic fistula, and the secondary outcome was the postoperative mortality.Results
Seven studies, involving 1359 patients, met the inclusion criteria for this review. In these studies, sample sizes ranged from 75 to 252 patients. In total, 679 patients were given octreotide and 680 patients formed the control group. Perioperative octreotide is associated with a significant reduction in the incidence of pancreatic fistula after elective pancreatic surgery, with a relative risk of 0.59 (95% confidence interval 0.41–0.85, p = 0.004). However, this risk reduction was not associated with a significant difference in postoperative mortality (p > 0.05).Conclusions
The review revealed that perioperative octreotide is associated with a significant reduction in the incidence of pancreatic fistula after elective pancreatic surgery. However, this risk reduction was not associated with a significant difference in postoperative mortality; further studies are warranted to confirm the results of this metaanalysis and to define which patient subgroups might benefit the most from prophylactic octreotide administration. 相似文献16.
