研究目的:

主要目标: 评估为期14天的术前口服丁酸甘油酯糖浆方案在年龄>=65岁、因原发性结直肠癌接受结直肠手术的成年患者中的耐受性和安全性特征。 次要目标: 1.评估可行性指标(招募情况、依从性、保留率),为未来的III期临床试验提供依据。 2.在拟定的评估计划下,估算该人群中术后谵妄(POD)的发生率和持续时间。 3.探索围手术期血浆丁酸盐、神经标志物和肠道微生物组的变化,以及它们与术后谵妄(POD)和围手术期因素之间的关联。  

Objectives of Study:

Primary Objective: To assess the tolerability and safety profile of a 14 day preoperative oral tributyrin syrup regimen in adults aged >=65 undergoing colorectal surgery for primary colorectal carcinoma. Secondary Objectives 1. To evaluate feasibility metrics (recruitment, adherence, retention) to inform a future phase III trial. 2. To estimate the incidence and duration of POD in this population under the proposed assessment schedule. 3. To explore perioperative changes in plasma butyrate, neuro markers and gut microbiome and their associations with POD and perioperative factors.

纳入标准:

Inclusion criteria

排除标准:

1. 年龄 < 65岁; 2. 无法给予知情同意;或 3. 结直肠手术并非针对原发性结直肠癌进行,或计划在同一手术期间进行其他主要手术;或 4. 已知对丁酸盐有不良反应的患者;或 5. 急诊手术,或从评估到预期手术日期少于15天;或 6. 正在服用益生菌或丁酸盐补充剂的患者。 只要患者被认为有能力为自己的手术提供知情同意,我们将接受其有资格为本试验提供知情同意,因为轻度认知障碍(MCI)很常见且通常处于亚临床状态。事实上,由于丁酸盐对神经炎症的有益作用,这些患者在理论上甚至更有可能从丁酸盐补充中获益。为了尽量减少因本研究样本量较小而导致治疗组间MCI不平衡所产生的混杂效应,随机分组将根据患者是否患有MCI进行分层。咨询时患有谵妄的患者将被排除在外,因为他们被认为没有能力提供知情同意。

Exclusion criteria:

1. Age < 65 years old 2. Unable to give informed consent 3. Colorectal surgery not performed for primary colorectal carcinoma, or additional major procedures planned in the same setting 4. Patients known to have adverse reactions to butyrate 5. Emergency operation or expected date of operation less than 15 days from assessment 6. Patients taking probiotics or butyrate supplements As long as the patients are considered competent to give their own informed consent for surgery, we will accept them to be eligible to give informed consent for this trial because mild MCI is common and often subclinical. In fact, these patients may theoretically be even more likely to derive benefits from butyrate supplementation due to its beneficial effects on neuroinflammation. To minimize confounding effect due to imbalance in MCI between treatment groups due to the small sample size of this study, the randomization will be stratified by whether the patients with and without MCI. Patient with delirium at the time of consultation will be excluded because they are considered incompetent to give informed consent.

随机方法(请说明由何人用什么方法产生随机序列):

在获得知情同意后,受试者将按1:1的比例被随机分配到干预组(丁酸甘油酯糖浆)或安慰剂组(外观和口味相同的糖浆)。随机化和分配隐藏将由REDCap(一个基于网络的安全研究数据平台)进行管理。随机化将按以下因素进行分层:(1)是否需要进行术前肠道准备;(2)患者是否存在既存的认知功能障碍。

Randomization Procedure (please state who generates the random number sequence and by what method):

After obtaining informed consent, the subjects will be randomly assigned in a 1:1 ratio to either the intervention group (glycerol butyrate syrup) or the placebo group (syrup with the same appearance and taste). Randomization and allocation hiding will be managed by REDCap (a web-based security research data platform). Randomization will be stratified based on the following factors: (1) Whether preoperative intestinal preparation is required; (2) Whether the patient has existing cognitive dysfunction.
