研究目的:

通过回顾性分析初次膝关节置换术患者的临床资料,明确术后便秘的发生情况,筛选出可能导致术后便秘的危险因素,为临床制定针对性的预防和干预措施、降低术后便秘发生率、改善患者术后生活质量提供循证医学依据。  

Objectives of Study:

By retrospectively analyzing the clinical data of patients who underwent primary knee arthroplasty, this study aims to clarify the incidence of postoperative constipation, identify the potential risk factors that may lead to postoperative constipation, and provide evidence-based medical support for formulating targeted clinical prevention and intervention measures, reducing the incidence of postoperative constipation, and improving patients' postoperative quality of life.

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)在研究期间于浙江医院接受单侧初次人工膝关节置换术(包括全膝关节置换术或单髁膝关节置换术); (2)拥有完整的电子病历数据,包括基线人口统计学信息、围手术期记录(如手术详情、用药情况)及术后结局指标(如排便频率、症状记录)。

Inclusion criteria

(1) Underwent primary unilateral PKA (either TKA or UKA) at Zhejiang Hospital during the study period; (2) Had complete EMR data, including baseline demographic information, perioperative records (e.g., surgical details, medication use), and postoperative outcomes (e.g., defecation frequency, symptom documentation).

排除标准:

(1)术前 6 个月内有慢性便秘病史(依据罗马 IV 标准定义:反复出现便秘症状≥3 个月,且症状起始时间距诊断≥6 个月); (2)既往患有严重胃肠道疾病,包括肠梗阻、炎症性肠病(克罗恩病或溃疡性结肠炎)或胃肠道恶性肿瘤(以排除已存在的胃肠道功能障碍作为混杂因素); (3)术后出现严重并发症(如人工关节感染、感染性休克、急性心肌梗死或脑卒中),因为这些疾病及其治疗手段(如血管加压药)会独立影响胃肠动力; (4)存在认知障碍(如阿尔茨海默病、卒中后认知功能障碍)或精神疾病(如精神分裂症、双相情感障碍),导致无法可靠报告排便症状; (5)合并终末期恶性肿瘤或预期生存期<3 个月。

Exclusion criteria:

(1) They had a history of chronic constipation within 6 months before surgery, defined by the Rome IV criteria (recurrent constipation symptoms for >=3 months, with onset >=6 months before diagnosis) ; (2) They had preexisting severe GI diseases, including intestinal obstruction, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), or GI malignancy (to eliminate preexisting GI dysfunction as a confounder); (3) They developed severe postoperative complications (e.g., prosthetic joint infection, septic shock, acute myocardial infarction, or stroke), as these conditions and their treatments (e.g., vasopressors) independently affect GI motility; (4) They had cognitive impairment (e.g., Alzheimer’s disease, post-stroke cognitive deficit) or psychiatric disorders (e.g., schizophrenia, bipolar disorder) that prevented reliable reporting of defecation symptoms; (5) Merge with end-stage malignant tumors or expected survival of less than 3 months.
