【摘要】：目的盆腔放射病(pelvic radiation disease,PRD)为放疗后盆腔内多器官、多部位损伤,患者在病变小肠切除术后存在便频、便失禁等症状。直肠在盆腔放疗中是最易受放射性损伤的部位,目前针对PRD患者肛管直肠功能的研究尚不充分。文中主要了解宫颈癌伴慢性PRD患者的肛管直肠功能,并为PRD的治疗及预后判断提供依据。方法收集2014年1月至2015年1月期间南京军区南京总医院普通外科住院患者,分别纳入需行小肠切除术的宫颈癌伴PRD患者及健康对照者。健康对照者来自门诊体检人群。在排除了高血压、糖尿病等全身性疾病及便秘、盆底失迟缓等消化系统疾病后分别入PRD组(n=20)和对照组(n=20),根据年龄进行配对。所有受试者均完成肠镜、肛门测压。根据肠镜结果评估放射性直肠黏膜损伤程度,比较2组间肛管直肠测压结果。结果研究所纳入的所有研究对象均无直肠狭窄、梗阻。PRD组的肛管静息压为(47.23±9.08)mm Hg,与对照组[(58.25±9.24)mm Hg]比较,差异有统计学意义(P0.05);肛管最大收缩压PRD组为(75.92±30.15)mm Hg,与对照组[(146.50±18.76)mm Hg]比较,差异有统计学意义(P0.01);肛管舒张压PRD组为(23.30±12.49)mm Hg,与对照组[(39.10±9.99)mm Hg]比较,差异有统计学意义(P0.01);直肠排便压PRD组为(22.85±16,69)mm Hg,与对照组[(50.90±9.14)mm Hg]比较,差异有统计学意义(P0.01);直肠最大耐受量PRD组为(112.85±51.34)m L,与对照组[(173.50±48.15)m L]比较,差异有统计学意义(P0.01);2组在直肠初始阈值(P=0.416),直肠排便感觉阈值(P=0.161);括约肌功能长度(P=0.313)方面差异均无统计学意义。结论宫颈癌伴PRD患者因放疗致其肛门内外括约肌功能受损,直肠最大耐受容量减少。肠道手术前需评估其肛管直肠的神经与肌肉功能,以制定合适的手术方案,从而最大程度改善PRD患者术后的生活质量。
[Abstract]:Objective pelvic radiation sickness (pelvic radiation disease,PRD) is a multiple organ and multiple site injury in the pelvis after radiotherapy. The patients have frequent stool and incontinence after resection of the diseased small intestine. Rectum is the most vulnerable site of radiation injury in pelvic radiotherapy. At present, the study of anorectal function in patients with PRD is not sufficient. In this paper, we mainly investigate the anorectal function of patients with cervical cancer with chronic PRD, and provide the basis for the treatment and prognosis of PRD. Methods from January 2014 to January 2015, the inpatients in general surgery of Nanjing General Hospital of Nanjing military region were included in cervical cancer with PRD and healthy controls. The healthy control group came from the outpatient medical examination population. After excluding hypertension, diabetes mellitus and other digestive system diseases such as constipation and pelvic floor retardation, PRD group (n 鈮，
