Objective: To explore the advantages of endoscopy combined with contrast fistulography in the clinical diagnosis and treatment of chronic wound with sinus tract adjacent to body cavity. Methods: Thirty-two patients (14 males and 18 females, aged 17 to 87 years) of chronic wounds with sinus tracts adjacent to body cavity, who underwent endoscopy combined with contrast fistulography (CT or magnetic resonance imaging) for the diagnosis and treatment in the Outpatient Department of Wound Healing Center of our hospital from October 2017 to March 2019, were enrolled in the study. Their diagnosis and treatment results were retrospectively analyzed. The following data were calculated. (1) The incidence rates of sinus wound involving body cavity or fistula. (2) The detection rates of sinus wound involving body cavity detected by routine examination and by endoscopy combined with contrast fistulography. (3) The detection rate of pathological features at deep part of wound by routine examination and by endoscopy combined with contrast fistulography. (4) The proportion of patients who benefited from routine examination and from endoscopy combined with contrast fistulography. Data were processed with paired chi-square test and Fisher's exact probability test. Results: (1) The incidence rate of sinus wound involving body cavity was 43.75% (14/32); the incidence rate of fistula was 0. (2) The detection rate of sinus wound involving body cavity detected by endoscopy combined with contrast fistulography was 43.75% (14/32), which was obviously higher than that by routine examination [12.50% (4/32), χ(2)=32.0, P<0.01]. (3) The detection rate of pathological features at deep part of wound by endoscopy combined with contrast fistulography was 37.50% (12/32), which was obviously higher than that by routine examination (0, P<0.01). (4) The proportion of patients who benefited from endoscopy combined with contrast fistulography was 71.43% (20/28), which was obviously higher than that from routine examination [12.50% (4/32), χ(2)=21.6, P<0.01]. Conclusions: Compared with routine examination, endoscopy combined with contrast fistulography is more accurate in detecting chronic wound with sinus tract adjacent to body cavity. The diagnosis and treatment of chronic wound with sinus tract adjacent to the body cavity can benefit from this joint examination.
目的： 探讨内窥镜联合造影检查在邻近体腔的慢性窦道创面的临床诊疗中的优势。 方法： 选择笔者单位创面修复中心门诊2017年10月—2019年3月收治的32例(男14例、女18例，年龄17～87岁)接受内窥镜联合造影检查(CT或磁共振成像)诊疗的、邻近体腔的慢性窦道创面患者，对其诊疗结果进行回顾性分析。统计以下指标：(1)涉及体腔的窦道创面和瘘管发生率。(2)一般检查和内窥镜联合造影的涉及体腔的窦道创面检出率。(3)一般检查和内窥镜联合造影的创面深部病理特征检出率。(4)一般检查和内窥镜联合造影检查后获益患者比例。对数据行配对χ(2)检验、Fisher确切概率法检验。 结果： (1)本组患者的涉及体腔的窦道创面发生率为43.75%(14/32)，瘘管发生率为0。(2)本组患者内窥镜联合造影的涉及体腔的窦道创面检出率为43.75%(14/32)，明显高于一般检查的12.50%(4/32)，χ(2)＝32.0，P<0.01。(3)本组患者的内窥镜联合造影的创面深部病理特征检出率为37.50%(12/32)，明显高于一般检查的0(P<0.01)。(4)本组患者内窥镜联合造影检查后获益患者比例为71.43%(20/28)，明显高于一般检查后的12.50%(4/32)，χ(2)＝21.6，P<0.01。 结论： 相较一般检查，内窥镜联合造影技术对邻近体腔的慢性窦道创面的检查更为准确，邻近体腔的慢性窦道创面的诊疗可因此技术的支持而获得益处。.
