研究设计:

横断面 

Study design:

Cross-sectional 

研究目的:

1.明确经腹超声评估胃肠镜检查前患者胃内液体量的临床可行性与准确性,为胃排空状态评估提供客观量化依据。 2.基于经腹超声检测结果,探索不同人群(如不同年龄、基础疾病状态、清肠剂使用情况等)胃肠镜检查的最佳时机。  

Objectives of Study:

1. To clarify the clinical feasibility and accuracy of transabdominal ultrasound in assessing gastric fluid volume in patients before gastrointestinal endoscopy, and to provide an objective and quantitative basis for evaluating gastric emptying status. 2. Based on transabdominal ultrasound findings, to explore the optimal timing of gastrointestinal endoscopy in different populations (e.g., different ages, underlying diseases, laxative use, etc.).

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.拟在本院行普通胃肠镜检查的门诊患者; 2.年龄18-80周岁; 3.自愿遵守研究方案,签署知情同意书 4.能够配合完成经腹超声检查及相关资料收集。

Inclusion criteria

1. Outpatients scheduled to undergo routine gastrointestinal endoscopy at our hospital; 2. Aged 18–80 years; 3. Voluntarily comply with the study protocol and sign the informed consent form; 4. Able to cooperate in completing transabdominal ultrasound and relevant data collection.

排除标准:

1. 有经腹超声检查禁忌证者(如严重肥胖、腹部手术史导致腹腔粘连、胃肠道穿孔、大量腹水等); 2. 胃排空功能严重异常者(如胃瘫、幽门梗阻等); 3. 严重肝肾功能不全、凝血功能障碍、精神疾病无法配合者; 4. 妊娠或哺乳期女性; 5. 近1周内有消化道出血、剧烈呕吐、腹痛等急性病症者; 6. 拒绝参与本研究或无法完成随访者。

Exclusion criteria:

1. Patients with contraindications to transabdominal ultrasound (e.g., severe obesity, abdominal adhesions due to prior abdominal surgery, gastrointestinal perforation, massive ascites, etc.); 2. Patients with severely impaired gastric emptying (e.g., gastroparesis, pyloric obstruction, etc.); 3.Patients with severe hepatic or renal insufficiency, coagulation disorders, or psychiatric disorders precluding cooperation; 4. Pregnant or lactating women; 5. Patients with acute conditions within the past week, such as gastrointestinal bleeding, severe vomiting, or abdominal pain; 6. Patients who refuse to participate in the study or are unable to complete follow-up.
