概括
在手术前的胆汁排水显著增加了胰腺切除术患者的阳性胆汁培养,但不会增加胰腺瘤风险. 对于这些患者来说,标准的抗生素预防似乎不足.
科学领域:
- 手术瘤学手术瘤学
- 胃肠病学 胃肠病学
- 传染性疾病 传染性疾病
背景情况:
- 胰腺切除术携带高发病率,通常是由于术后感染.
- 阳性胆汁培养,特别是在胆汁排水后,与胰腺瘤严重程度的增加相关.
- 目前的抗生素预防可能不足以对抗胆汁排水中发现的病原体.
研究的目的:
- 在手术前胆汁排水和没有胆汁排水的患者中比较阳性胆汁培养率和抗生素耐药性.
- 评估阳性胆汁培养与术后胰腺囊 (POPF) 风险之间的关联.
主要方法:
- 对接受胰腺二管切除术 (2015-2022) 的患者进行了回顾性单中心研究.
- 在之前有和没有胆汁排水的患者之间对手术内胆汁样本的比较.
- 对微生物学模式,抗生素敏感性和POPF率的分析.
主要成果:
- 阳性胆汁培养在先前排水组 (90.9%) 显著高于没有排水组.
- 多微生物生长很常见 (80%),其中*Klebsiella pneumoniae*和*Enterococcus faecium*是普遍存在的.
- 观察到高抗生素耐药性;85%的排水组显示耐药性.
- 排水组的POPF率为50%,无排水组为21.4%,没有统计学上显著的差异.
结论:
- 在手术前的胆汁排水导致胰腺切除术中胆汁培养的发生率更高.
- 尽管增加了阳性培养,但手术前胆道排水并没有增加胰腺的风险.
- 标准的抗生素预防在这种患者队列中对已识别的微生物特征是不充分的.

Development of Antibiotic Resistance
1.7K
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Acute Pyelonephritis II: Diagnostic Studies and Management
532
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Urine Studies II: Urine Culture and Sensitivity Test
1.6K
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
