激光指示光引导鼻内镜下手术治疗外伤性鼻泪管阻塞伴泪囊移位

目的 观察通过激光指示光引导定位泪囊，行鼻内镜下泪囊鼻腔吻合手术治疗泪囊移位的方法。方法 对12例（12眼）经CT、MRI或泪囊造影后证实泪骨、鼻骨、或上颌骨鼻突骨折造成鼻泪管阻塞和泪囊移位，在局麻下激光指示光针于上或下泪小管进入泪囊，鼻内镜光源反复打开和关闭以观察指示光最靠近骨窗的最佳位置，切开相应鼻黏膜，做骨窗，然后顺势扩大鼻黏膜和骨窗口，准确找到泪囊后放入泪囊鼻腔引流支架。结果 12眼外伤性鼻泪管阻塞伴泪囊移位采用上述方法均顺利完成泪囊鼻腔吻合手术，术中大大减少了手术探查寻找泪囊带来的鼻黏膜和骨组织过多的损伤，术中患者痛苦少，术后恢复快，鼻腔换药次数减少。结论 激光指示光引导行鼻内镜下泪囊鼻腔吻合手术其定位准确，操作简单，组织损伤少，手术时间短。     

内镜下置入幽门支架治疗进展期胃窦癌胃出口梗阻疗效观察

背景：胃出口梗阻（GOO）是进展期胃癌的常见并发症，此类患者手术切除机会较低，生存期短，生活质量差。目的：评价内镜下置入幽门支架对进展期胃窦癌合并GOO的姑息治疗作用。方法：2012年1月～2013年5月宝山区中西医结合医院32例表现为不能进食或进食后呕吐，经上消化道造影证实存在G00并接受内镜下置入幽门支架治疗的进展期胃窦癌患者纳入研究。治疗前后以GOO记分系统（GOOSS）和焦虑自评量表（SAS）、抑郁自评量表（SDS）评价患者的梗阻情况和心理状态，观察术后并发症发生情况。结果：32例患者均成功置入支架且膨胀良好，术后1周和4周GOOSS评分较术前明显增高，SAS、SDS评分较术前明显降低，差异均有统计学意义（P〈0．05）。1例患者发生支架移位，2例发生支架阻塞，未见穿孔和明显出血病例。结论：对于不能手术的进展期胃窦癌合并G00，内镜下置入幽门支架是一种微创、安全、有效的姑息治疗方法，可缓解梗阻症状，改善患者的焦虑、抑郁倾向。

Colorectal Stenting for Malignant and Benign Disease: Outcomes in Colorectal Stenting

INTRODUCTION: Self-expanding metal stents are now an established treatment for malignant colonic obstruction. Favorable outcomes have been reported both for cancer palliation and treatment of acute obstruction as a bridge to surgery. However, little data exists regarding the use of stents for benign colonic obstruction.METHODS: All cases of colonic stent insertion occurring between December 1996 to October 2002 were reviewed. During the study period, 36 patients with malignant obstruction and 6 patients with benign obstructive disease underwent placement of self-expandable stents using a combined endoscopic and fluoroscopic technique.RESULTS: Stent placement was successful in 36 of 42 patients (86 percent). Complications occurred in 16 of 36 patients (44 percent): migration (n = 7), reobstruction (n = 5), perforation (n = 2), fistula formation (n = 1), and stent fracture (n = 1). Stent placement was successful in 100 percent of patients with benign strictures but poststent migration was frequent (2/6).CONCLUSIONS: Stent insertion provided an effective outcome in patients with malignant colonic obstruction as a palliative and preoperative therapy. Although a relatively high migration rate was observed in patients with benign strictures, stenting was still effective in providing luminal patency (median follow-up, 7.5 months). Stenting should be considered as a first-line treatment for malignant strictures and as a potential therapy for selected benign strictures.
