乙状结肠

Figure 20: Transverse CT image in a 57-year-old woman with diverticulitis of sigmoid colon shows wall thickening in sigmoid colon and scattered diverticula.

图为一例57岁老年女性乙状结肠憩室炎患者，图像显示乙状结肠壁增厚并散在憩室。

Met hod 124 patients with UC were radomly assigned to treatment group giving drugs through sigmoidoscope and contrast group giving enemas.

用随机对照方法对 12 4例溃疡性直肠乙状结肠炎患者分为治疗组 6 4例与对照组 6 0例，治疗组给予乙状结肠直视下给药，对照组给予局部灌肠治疗，疗程 4周。

Methods: A population-based multicenter randomized trial comparing 3 strategies was used:(1) biennial immunologic fecal occult blood test,(2)"once only" sigmoidoscopy, and (3)"once only" colonoscopy.

一项对人群的多中心随机试验比较3种方法：(1) 2年一次的免疫学大便潜血检查，(2)一次乙状结肠镜检查，和(3)一次乙状结肠镜检查。

This neoplasm was located in the sigmoid colon, just out of reach of digital examination, but easily visualized with sigmoidoscopy .

此肿瘤位于乙状结肠，直肠指诊摸不到，但是乙状结肠镜检查很容易发现。

Methods:60 cases with low rectal and anus carcinoma who underwent laparoscopic Miles operation were divided into two groups.The experimental group (30 cases) received extraperitoneal sigmoidostomy while the control group (30 cases) received traditional intraperitoneal procedure.Postoperative complications caused by sigmoidostomy and defecation function in these two groups were compared.

将接受腹腔镜Miles术的60例低位直肠癌、肛管癌患者分为两组，实验组30例行腹膜外乙状结肠造口术，对照组30例行传统的腹膜内乙状结肠造口术，比较两组患者的造口并发症和排便功能。

Sigmoid mesocolon hernias account for 6% of all internal hernias (1 3) and are divided into three categories (45): intersigmoid hernia, trans mesosigmoid hernia, and intermesosigmoid hernia.

乙状结肠系膜疝占所有腹内疝的6%，可以分为3类：乙状结肠间疝；经乙状结肠系膜疝和乙状结肠系膜间疝。

The sigmoid mesocolon is a peritoneal fold attaching the sigmoid colon to the pelvic wall. The apex is divided near the left common iliac artery and serves as a potential site for an internal hernia.

乙状结肠系膜是固定乙状结肠到骨盆壁的腹膜皱襞，其尖端在接近左侧髂总动脉处分叉，成为潜在的腹内疝的部位。

Our aim in this observational, prospective, noncontrolled studywas to detect, in 29 patients who underwent abdominal aorticaneurysm surgery, correlations between the incidence ofpostoperative organ failure and intraoperative changes in arterialand portal blood lactate; changes in intramucosal sigmoid pH; differences between sigmoid PCO2 and arterial PCO2 ( CO2);and hemoglobin.

我们在这个观察性、前瞻性、非对照研究中的目的是探求29例腹主动脉瘤手术后患者器官衰竭发生率与术中动脉和门静脉乳酸变化、乙状结肠粘膜内 pH变化、乙状结肠粘膜 PCO2和动脉 PCO2差值（ΔCO2）以及血红蛋白的关系。

METHODS: We measured levels of blood hydroperoxides as an indexof oxidative injury of cellular components, as well as plasmaferric-reducing ability as an index of total antioxidant potential,during sigmoidectomy under four conditions: open sigmoidectomywith sevoflurane anesthesia, laparoscopic sigmoidectomy withsevoflurane anesthesia, open sigmoidectomy with propofol anesthesia,and laparoscopic sigmoidectomy with propofol anesthesia.

在四种不同麻醉方法下乙状结肠切除术中，测定血液中的过氧化氢水平作为细胞氧化损伤的指标，以及血浆铁还原能力作为总抗氧化潜力的指标：七氟醚麻醉开腹乙状结肠切除术，七氟醚麻醉腹腔镜下乙状结肠切除术，异丙酚麻醉开腹乙状结肠切除术，异丙酚麻醉腹腔镜下乙状结肠切除术。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
