目的探讨鼻内镜下经鼻腔直接入路行蝶窦及中颅窝手术的方法. 方法鼻内镜下经较宽大一侧鼻腔将中鼻甲向外推移,鼻腔扩张器扩大视野,直达并开放蝶窦前壁, 鼻内镜与显微镜联合切除病变. 结果 10例孤立性蝶窦炎术后症状消失.6例蝶窦囊肿、脑膜瘤均一次手术切除.32例垂体腺瘤17例全切除,12例次全切除,3例大部分切除,术后补充X刀治疗.48例术后随访6个月～3.5年,平均2.5年,蝶窦囊肿、蝶窦炎、脑膜瘤无复发,3例垂体腺瘤复发,无颅内感染并发症,无鼻腔粘连、鼻出血等鼻腔并发症. 结论鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术损伤小、出血少、手术时间短、效果好.     

EVALUATION OF THE LOOPING FORMATION AND PAIN DURING INSERTION INTO THE CECUM IN COLONOSCOPY

Introduction: One of the causes of pain during insertion of the colonoscope is stretching of the mesenterium by loop formation. The degree of pain differs according to the type of loop formation. Our aims were to study the accuracy of the colonoscopist’s assessment of the presence and type of loop formation and to study the degree of pain in relation to the type of loop by administering the visual analog scale (VAS). Methods: Two hundred and fifty‐seven consecutive patients were enrolled. All procedures were performed by two experienced colonoscopists who were blind to magnetic endoscope imaging view. After the colonoscopy, the colonoscopist was asked to assess the presence and type of loop formation. The degree of pain was assessed using the VAS. Results: The accuracy of estimating N loop, alpha loop, absence of loop formation and U loop was each over 70%. The accuracy of estimating gamma and splenic loop was significantly lower than the accuracy of estimating U loop. Colonoscopy was significantly more painful in women than in men. The degree of pain was significantly higher upon formation of reverse alpha loop and gamma and splenic loop than upon formation of N loop and U loop. Conclusions: Upon formation of reverse alpha loop or gamma and splenic loop, patients experienced more pain and it was difficult for the endoscopists to assess these loops. As women had severe pain compared with men, the use of a pediatric colonoscope or higher dosage of sedation in women should be considered.     

炎性肠梗阻15例诊治体会

目的探讨炎性肠梗阻的诊断和治疗。方法分析15例炎性肠梗阻的临床特点和治疗。结果15例经保守治疗,其中1例因肠扭转缺血损伤严重,出现全身性炎症反应综合征致多脏器衰竭死亡外,其他病例均痊愈,平均治愈时间为12.6d。结论炎症性肠梗阻由无菌性炎症致广泛肠粘连引起,应用小剂量激素减缓炎症反应,抗生素防止肠道菌群易位,经内镜逆行置入肠减压管及营养支持治疗,多数病例可保守治愈。     

鼻内镜下等离子低温射频治疗常年性变应性鼻炎的临床观察

目的探讨鼻内镜下等离子低温射频治疗常年性变应性鼻炎(PAR)的疗效及其优越性。方法在鼻内镜下用等离子低温射频治疗PAR48例,按照海口会议修订的“过敏性鼻炎诊断和疗效评定标准”,用计分法分别评定其疗效。结果该组48例术后随访半年进行评价,其中显效27.1%(13/48),有效58.3%(28/48),无效14.6%(7/48),总有效率为85.4%。疗效评分显示治疗前平均总分为(9.58±1.69)分,治疗后为(5.63±1.15)分(P<0.05)。结论鼻内镜下等离子低温射频烧灼筛前神经终末区域治疗PAR,具有简便、安全等优点,短期效果显著,特别适用于临床上应用抗组胺类药物及鼻内应用糖皮质激素治疗效果不甚理想及由于各种原因不能长期接受抗组胺类药物及鼻内应用糖皮质激素治疗的患者;但长期疗效有待进一步研究。     

老年性白内障手术心电监护

目的：评价老年性白内障超声乳化伴人工晶体植入术心电监护的临床意义。方法：随机选择老年性白内障超声乳化伴人工晶体植入术行心电监护244例（287只眼）。结果：手术中出现血压明显升高，心肌缺血及心律失常者114例，经及时处理后恢复。结论：老年性白内障患者，术中行心电监护对提高手术安全性十分重要。
