Bile-Duct Stone Removal under Direct Transnasal Cholangioscopy Using an Ultraslim Upper Endoscope

The transnasal endoscopic examination using an ultraslim upper endoscope may be more comfortable and less stressful than the peroral approach. Transnasal endoscopic retrograde cholangiopancreatography (ERCP), endoscopic nasobiliary drainage, and direct peroral cholangioscopy using an ultraslim upper endoscope have recently been reported. An 82-year-old woman with a previous history of endoscopic sphincterotomy and stone removal was admitted with acute cholangitis. Instead of conventional ERCP, we performed direct transnasal cholangioscopy (TNC) using an ultraslim upper endoscope for biliary decompression and stone removal because of her unstable vital signs. Direct TNC using an ultraslim upper endoscope may be useful in selected patients with biliary disease.     

计算机辅助导航技术在鼻窦及鼻颅底手术中的应用

目的:探讨计算机辅助导航技术在鼻窦及鼻颅底手术中的应用价值。方法:49例患者(复发性鼻窦炎、鼻息肉25例,鼻腔鼻窦肿瘤9例,脑脊液鼻漏7例,脑膜脑膨出2例,先天性后鼻孔闭锁4例,垂体瘤1例,中颅窝底异物1例)均在计算机辅助导航下行鼻内镜手术。结果:计算机辅助导航术前准备时间为5～13min,平均7min,靶点误差≤1.5mm。49例患者均顺利完成手术,无并发症出现。结论:计算机辅助导航系统有助于术者正确判断鼻窦、颅底及相邻的解剖标志,可提高手术的精确性和安全性,减少术中及术后并发症的发生。     

鼻内镜下上颌骨囊肿开放术

目的:探讨鼻内镜下上颌骨囊肿开放术的有效性和可行性。方法:对13例侵犯上颌窦或鼻腔底的上颌骨囊肿在鼻内镜下行上颌骨囊肿开放术,即行鼻内镜下囊肿下鼻道或鼻腔底开放术,囊肿囊壁被全部或部分切除。结果:随访6～36个月,13例患者未出现面部隆起、鼻塞及鼻腔溢液等症状,囊肿无复发。结论:鼻内镜下上颌骨囊肿开放术适用于侵犯上颌窦或鼻腔底的上颌骨囊肿,较传统手术创伤小,简单高效,受侵牙齿可尽量保存。     

鼻内镜下视神经减压术治疗外伤性视力完全丧失的预后相关因素分析

目的探讨鼻内镜下视神经减压术对外伤性视力完全丧失的疗效,并评估其预后相关因素。方法回顾性分析85例外伤性视力完全丧失患者的临床资料,通过单因素分析和Logistic回归分析来评估其潜在的预后相关因素。结果鼻内镜下视神经减压术后,患者总体视力提高44．7％（38J85）。单因素分析显示：筛窦和（或）蝶窦内积血是视力改善的负性因素。而Logistic回归分析显示：外伤到手术的时间超过3d、筛窦和（或）蝶窦内积血与外伤性视力丧失的预后呈负性相关。结论筛窦和（或）蝶窦内积血、外伤到手术的时间超过3d是外伤性视力丧失视力恢复的危险因素。视力完全丧失的患者伤后3d内如能实施手术,视力可能得以较好改善。     

鼻内窥镜中、下鼻道联合造孔术治疗慢性上颌窦炎疗效观察

目的　观察鼻内窥镜中、下鼻道联合造孔术治疗慢性上颌窦炎的疗效。方法　在作功能性鼻内窥手术治疗 34例慢性上颌窦炎时 ,在下鼻道造孔 ,6mo后随访。结果　 34例慢性上颌窦炎经鼻内窥镜中、下鼻道联合造孔术 6mo后随访 ,其中 2 4例痊愈 (71% ) ,好转 9例 (2 7% ) ,无效 1例 (2 % )。结论　鼻内窥镜中、下鼻道联合造孔术治疗慢性上盒颌窦炎疗效高、痛苦少 ,值得应用。     

Bilateral congenital choanal atresia

Our experience with the diagnosis and management of bilateral choanal atresia is presented. Four patients were treated by endoscopic transnasal approach followed by stenting with portex endotracheal tube for four to six weeks. Meticulous postoperative care particularly stent management is crucial for successful treatment of choanal atresia.
