研究目的: |
本研究通过在小肠减压状态下行滋养型口服营养补充,应用HE染色、IHC、16S rRNA测序、ELISA法等观察肠屏障、肠道微生物群、术后肠功能恢复、感染性并发症和住院时间等指标,系统评估小肠减压状态下给予滋养性口服营养补充对临床结局的影响。 |

Objectives of Study: |
This study systematically evaluated the effects of trophic oral nutritional supplementation (ONS) during small bowel decompression on clinical outcomes. By administering trophic ONS in the decompressed state, we observed multiple indicators—including intestinal barrier function, gut microbiota, postoperative bowel function recovery, infectious complications, and length of hospital stay—using H&E staining, immunohistochemistry (IHC), 16S rRNA sequencing, and enzyme-linked immunosorbent assay (ELISA). |

随机方法(请说明由何人用什么方法产生随机序列): |
随机分配序列由一名不参与患者招募和干预实施的独立统计人员使用 SPSS 27.0 软件生成。采用区组随机化方法,区组长度设为 4,按 1:1 比例将受试者分配至干预组或对照组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The random allocation sequence was generated by an independent statistician who was not involved in patient recruitment or intervention delivery, using SPSS software (version 27.0; IBM Corp., Armonk, NY, USA). Block randomization with a block size of 4 was employed to assign participants to either the intervention group or the control group in a 1:1 ratio. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据采集采用纸质病例记录表与电子数据采集系统相结合的方式。研究团队依据方案设计标准CRF,由培训合格的研究人员实时填写。所有CRF数据经核查后,由两名数据管理员独立双份录入至ResMan电子数据采集平台。系统设有自动逻辑核查程序,数据管理过程中产生的质疑由研究者在线答复确认。全部数据操作过程均由系统稽查轨迹完整记录。数据清理完成后锁定数据库,导出标准化数据集供统计分析使用。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data were collected using a combination of paper Case Report Forms (CRFs) and an Electronic Data Capture (EDC) system. Standardized CRFs were designed based on the study protocol and completed in real time by trained research personnel. Following source data verification, data were independently double-entered into the ResMan EDC platform by two data managers. The system incorporated automated logic checks, and queries raised during data management were resolved online by the investigators. All data operations were documented with a complete audit trail. After data cleaning, the database was locked, and a standardized dataset was exported for statistical analysis. |
