目的：为灌肠术、Ｘ 光气钡造影、内镜检查等提供大肠的形态学基础。方法：３０ 具成人形态正常的大肠，分段测量大肠的长度、周径，按圆柱体积公式ｖ ＝ １／４πｃ２ｌ 和圆锥体体积公式ｖ ＝ １／１２πｃ２ｌ 分别计算出结肠和盲肠的体积；用浸水法测量游离大肠的体积。结果：大肠长１２６ ．９ ±２７ ．４ ｃｍ（ 盲肠、结肠、直肠盆内段分别为４３ ．６ ±１ ．５ ｃｍ ，１１３ ．３ ±２５ ．０ ｃｍ ，９ ．２ ±３ ．３ ｃｍ） 。微积分法和浸水法得出的大肠体积分别为８５０ ．１±４１１ ．２２ ｍＬ，７５６ ．６ ±９１ ．９ ｍＬ。结论：本文的结果可为临床灌肠术、气钡造影及内镜检查提供参考依据。
OBJECTIVE: To provide the morphological basis of large intestine for enema surgery, X-ray barium imaging, endoscopy and so on. Methods: 30 adult large intestine, the length of the large intestine measured, the circumference, according to the cylinder volume formula v = 1 / 4πc2l and cone volume formula v = 1 / 12πc2l were calculated colon and cecal volume; with water immersion Method to measure the volume of free colon. Results: Large intestine 126. 9 ± 27. 4 cm (cecum, colon, rectum, pelvic segments were 43.6 ± 1.5 cm, 113.3 ± 25.0 cm, 9.2 ± 3.3 cm). Calculus and water immersion method derived colorectal volume were 850. 1 ± 411. 22 mL, 756. 6 ± 91. 9 mL. Conclusion: The results of this paper can provide reference for clinical enema, barium barium and endoscopy.
