内镜专用直接测量尺的设计及临床应用价值

The design and value of clinical application of the dedicated and direct measuring scale for the endoscope

目的评价自行研制的内镜专用直接测量尺的临床应用价值。方法选择2010年7月至2011年9月山东省枣庄市市中区人民医院经病理和内镜确诊的患者64例,其中晚期食管癌20例,食管溃疡2例,胃溃疡11例,胃石2例,十二指肠球部溃疡14例,结肠息肉15例。常规内镜检查发现病灶,先目测估计病灶直径大小;然后采用自行研制的内镜专用直接测量尺,经内镜活检管道插入,刻度尺紧贴病灶,内镜下直视直接测量病灶直径大小。内镜下目测和内镜专用直接测量尺测量病灶直径比较采用配对t检验。结果 20例晚期食管癌、11例胃溃疡、14例十二指肠球部溃疡、15例结肠息肉患者内镜下目测病灶直径分别为(0.5±0.3)、(0.8±0.2)、(0.6±0.4)、(0.4±0.3)cm,均小于内镜专用直接测量尺测得的(0.7±0.2)、(1.0±0.2)、(0.9±0.2)、(0.5±0.2)cm,且差异均有统计学意义(t=7.646,5.860,9.050,2.956;均P<0.01)。2例食管溃疡与2例胃石患者组病灶内镜下目测病灶直径分别为(0.7±0.1)、(3.9±1.2)cm,与内镜专用直接测量尺测得的(1.0±0.2)、(4.4±1.0)cm比较差异无统计学意义(t=3.000,5.000;均P>0.05)。结论内镜专用直接测量尺设计合理,使用方便。直接测量比目测估计更精确、更客观,更有利于疾病治疗前后的对比分析。

Objective To evaluate the value of clinical application of die dedicated and direct measuring scale for the endoscope which is designed by ourself. Methods Sixty-four patients who were diagnosed by pathology and endoscopy in Zaozhuang City Center District People＇s Hospital in Shandong Province from July 2010 to September 2011 were chosed. Twenty cases were advanced esophageal cancer, 2 cases were esophageal ulcer, 11 eases were gastric ulcer, 2 cases were gastrolith, 14 eases were duodenal ulcer, 15 cases were polyp of colon. The lesions were found by routine endoscopy, estimating the diameters of the lesions by visual observation, then inserting through the endoscopic biopsy pipe using the dedicated and direct measuring scale for the endoscope, closing to the lesion and measuring the diameters of lesions with endoscopy directly. The differences of diameters of lesions betweem estimated by visual observation and measured by dedicated and direct measuring scale for the endoscope were analyzed by paired t test. Results The diameters of lesions which were estimated by visual observation for 20 cases of advanced esophageal cancer, 11 cases of gastric ulcer, 14 cases of duodenal ulcer, 15 cases of colonic polyps were （0.5 ±0.3 ）, （0.8±0.2）, （0.6±0.4）, （0.4±0.3） em. They were all less than the diameters （0.7±0.2）, （1.0±0.2）, （0.9±0. 2）, （0. 5 ±0. 2） cm which were measured by the dedicated and direct measuring scale for the endoscope. The differences had statistically significant （ t = 7. 646, 5. 860, 9. 050, 2. 956, all P 〈0.01 ）. The diameters of lesions which were estimated by visual observation for 2 cases of esophageal ulcers and the 2 cases of gastrolith were （ 0.7 ± 0.1 ）, （ 3.9± 1.2 ） cm. Compared with the diameters （ 1.0 ± 0.2 ）, （4.4 ±1.0） cm which were measured by the dedicated and direct measuring scale for the endoscope, the differences had no statistically significant （ t = 3. 000, 5. 000, both P 〉 0.05 ）. Conclusions The dedicated and direct measuring scale for the endoscope has a reasonable design and is convenient to use. The direct measurement is more accurate, more objective and more conducive to comparative analysis before and after treatment than the visual estimation.
