息肉

Each polyp was isualized and resected using both a forward and retroflexed iew.

每个息肉采用前视和倒镜的方法进行了观察和切除。

METHODS Fifteen patients in whom the retroflexion technique was used for polyp remoal were prospectiely identified.

对15例采用倒镜技术进行息肉摘除的患者进行前瞻性研究。

All polyps, except two, were completely resected during the first session, using both the prograde and retroflexion approaches.

除两例外，所有息肉同时采用顺行和倒镜的方法在第一次均完整切除。

We describe the use of retroflexion in the colon as a useful and routine technique using a standard colonoscope for the resection of difficult sessile polyps.

我们描述了通过标准结肠镜采用结肠倒镜方法作为常规有效技术来切除困难的无蒂息肉。

Retroflexion complements the conentional prograde inspection of sessile polyps that are only partially isualized on prograde iew alone.

倒镜法补充了传统的顺行观察法只能部分观察到无蒂息肉。

Retroflexion combined with forward iewing allowed for a better assessment of the size and extent of all the polyps compared with forward iewing alone.

相对于仅采用前视，倒镜联合前视可以更好的评估息肉大小和范围。

All 5 patients of benign polyp were found to have excellent effect after Nd-YAG laser therapy, and so for, there was no recurrence. Two (esophageal cancer 1 and rectal cancer 1) of 19 patients of G-I cancer had excellent results with tumor size reduced over 90% and endoscope could pass through the stenotic area smoothly after Nd-YAG laser treatment. Six (esophageal cancer 2, gastric cancer 4) of them had good results with tumor size reduced 50-90% and patient could take semiliquid food after laser management. Eight patients (esophageal cancer 2, gastric cancer 4, rectal cancer 2) had fair effects with tumor size reduced less than 50%, but the oral intake or stool passage was improved. Three patients (15.8%) refused further endoscopy and laser management because of poor tolerance.

这5例良性息肉经雷射治疗后，肿瘤完全消失且目前无后发现象。19位恶性癌中，经Nd-YAG雷射治疗后，效果极佳（肿瘤大小减少90%以上，内视镜可通过肿瘤狭窄处）者2例（食道癌及直肠癌各1；效果佳（肿瘤大小减少50~90%，且病人可进食半流体食物）者6例（食道癌2，胃癌4）；效果尚可（肿瘤大小减少50%以下，但饮食进步或排便较过去进步）者8例（食道癌2，胃癌4，直肠癌2；3例患者(15.8%)因不能忍受内视镜及雷射治疗之痛苦，拒绝进一步的治疗而失败。

To study the expression of proliferating cell nuclear antigen in human gastric neoplasm and its clinical significance. The expression of PCNA was semiquantitatively analysed immunohistochemically in 10 gastric adenomatous polyp and 94 gastric carcinomas.

为了解增殖细胞核抗原在胃肿瘤中的表达及其临床意义，应用免疫组化技术，对胃肿瘤(胃腺瘤性息肉10例，胃癌94例)组织切片中PCNA含量进行半定量检测。

All 26 polyps were sessile, ranging from 1 to 6 mm in size (mean, 2.5 mm).

这26例息肉都无蒂，大小范围：1至6毫米（平均2.5毫米）。

Objective To investigate the value and safety of endoscopic mucosal resection in elderly patients with large sessile colorectal polyps.

目的 探讨内镜黏膜切除术对老年广基息肉病变的治疗价值及安全性。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
