神经移植重建面神经在腮腺癌根治术中的应用

目的：探讨腮腺深叶癌切除面神经后，即刻功能性修复的临床效果。方法：对1984年1月至2005年10月间收治的11例腮腺癌患者，术中采用将肿瘤连同腮腺及面神经切除，同时行颈丛神经移植重建面神经的治疗方法。结果：术后面神经功能均完全恢复，所有患者术后6个月复诊，见患者静态时面部对称，动态时口角轻度偏斜，术后一年两侧面部完全对称，睁、闭眼及提口角功能基本恢复正常。结论：腮腺癌根治术中采用颈丛神经移植能有效地恢复面神经的功能，既达到肿瘤切除的彻底性，又符合功能外科的发展要求，是一种比较理想的手术方法。     

不同疗法对肌筋膜疼痛病人的自主神经功能的影响

目的：本研究的目的是观察注射疗法及复合小针刀疗法治疗肌筋膜疼痛综合征对自主神经系统功能的影响。方法：选择40例诊断明确的肌筋膜疼痛病人，随机分为两组，每组20例。Ⅰ组：采用注射疗法治疗；IS组：采用注射疗法加小针刀治疗。观察两组病人治疗前后心率变异（HRV）的频域变化，低频LF、超低频LLF、高频HF、低高频比LF／HF及心率变异指数HR-Ⅵ；用视觉模拟评分法（VAS）评定治疗前后疗效并随访观察其远期疗效。结果：①HRV频域指标组内比较：LF、LLF、HF以及HRVI治疗前舆治疗后1min比较有显着性差异（P〈0．05），与5min、10min比较有非常显着性差异（P〈0．01）。LF／HF治疗前与治疗后5min、10min比较有显着性差异（P〈0．05）。组间治疗后1、5、10min，两两比较无显着性差异。②组间比较：病人治疗后临床症状、VAS评分均较治疗前降低．治疗前后IS组有非常显着性差异（P〈0．01）。两组VAS降低率有非常显着性差异（P〈0．01）。③回访病例中，两组治疗有效率比较有显着性差异（P〈0．05）。结论：注射疗法以及复合小针刀疗法均可有效改善肌筋膜疼痛病人的自主神经功能，其机制可能是通过调节、稳定自主神经系统功能达到缓解疼痛。注射疗法复合小针刀疗法的远期疗效优于单纯注射疗法。

Double congenital bronchoesophageal fistulae in an adult

We report adult congenital bronchoesophageal fistula with both symptomatic fistula and asymptomatic one. A 56-year-old woman with a history of cough after drinking fluids was diagnosed as bronchoesophageal fistula by upper gastrointestinal series that showed a diverticulum in the middle portion of the esophagus with a fistula between the esophagus and right lower lung. Esophagoscopy revealed an orifice of the fistula located 27 cm from the incisors. Computed tomography showed chronic inflammatory change with bronchiectasis in the S6 segment of the right lung. The patient underwent video assisted thoracic surgery that identified two fistulae without missing a symptomatic one, and both were successfully resected. The fistulae were lined by squamous epithelium and smooth muscle without evidence of malignancy, infection or chronic inflammation that were histologically compatible with congenital fistulae.

保留盆腔植物神经对老年男性患者术后性功能及排尿功能的影响

目的:探讨保留盆腔植物神经的直肠癌手术对老年男性患者性功能及排尿功能的影响。方法:1999~2005年因直肠癌手术的170例老年男性患者分为PANP组(含规范的TME手术方法)和非PANP(TME规范情况不详),对两组术后性功能、排尿功能和局部复发率进行回顾性总结、比较。结果:PANP组性功能与排尿功能明显优于非PANP组,但统计学无显著差异(P<0.05)。而PANP组局部复发率低于非PANP组(P>0.05)。结论:老年直肠癌患者应重视性功能和排尿功能的保护。

目的研究两种不同脊柱后路减压方法治疗胸腰段骨折脱位合并脊髓损伤的手术治疗效果。方法回顾分析本院1996年3月～2002年6月收治的胸腰段骨折脱位并脊髓损伤患者76例，按不同减压方法将其分为两组：切除一侧或两侧椎板、椎弓根或部分关节突行侧前方环状减压AF内固定者40例，为直接减压组；体位复位结合AF器械矫正复位36例，为间接减压组。统计学分析，两组资料具有可比性。对术后神经功能恢复情况，按ASIA神经功能评定标准进行评定。中晚期并发症，根据是否有腰背痛，下肢根性痛、麻木无力，两便功能障碍进行评定。生活能力按FIM评定。结果两组病例获6个月～5年随访，结果表明，术前脊髓完全性损伤，术后均无恢复；术前脊髓不完全性损伤，术后两组间比较差异无显著性。中晚期并发症发生，直接减压组高于间接减压组；术后生活自理能力，间接减压组好于直接减压组。结论间接减压手术方法治疗胸腰段骨折脱位合并脊髓损伤不失为一种早期治疗的首选方法。     

Anatomical Course of the Superficial Branch of the Radial Nerve and Clinical Significance for Surgical Approaches in the Distal Forearm

Abstract 10 embalmed cadaver forearms and wrists were dissected to determine the anatomical course of the superficial branch of the radial nerve in the distal forearm. The superficial radial nerve bifurcated in two branches at a mean of 54,7 mm proximal to the radial styloid. From the styloid process of the radius, the mean distance to the closest dorsal branch of the superficial radial nerve was 3,5 mm and the mean distance to the closest volar branch was 9,8 mm. The mean distance between the closest branch of the superficial radial nerve and Lister?s tubercle was 16,4 mm. The crossing point between the nerve and the cephalic vein was located at a mean of 54,3 mm proximal to the styloid process. At the level of styloid process the mean distance between the closest dorsal branch of the superficial radial nerve and the first dorsal compartment was 15,2 mm and between the closest volar branch and the first dorsal compartment 4,4 mm. Detailed knowledge of anatomic characteristics of the superficial branch of the radial nerve may help prevent injury during operations and treat traumatic lesions of the nerve. Because of great variations in the course of the superficial radial nerve we could not define an absolute safe zone for surgical procedures on the distal forearm. Iatrogenic lesions of the superficial radial nerve are described complications of percutaneous procedures. Therefore open surgical approaches are recommended. Daniela Klitscher and Lars Peter Müller contributed equally to this work.     

Impact of unilateral interposition sural nerve graft on the recovery of sexual function after radical prostatectomy in Japanese men: A preliminary study

PURPOSE: To determine the effect of an interposition nerve graft on sexual function after radical prostatectomy. METHODS: This study includes 64 patients, without hormonal therapy, who underwent a radical prostatectomy and intraoperative electrophysiological confirmation of cavernous nerve preservation. Twelve patients underwent a unilateral interposition sural nerve graft (UNG) for the resected neurovascular bundle. Twenty-one and 31 patients underwent bilateral nerve-sparing (BNS) and unilateral nerve-sparing (UNS) surgery without a nerve graft, respectively. As the age of patients was significantly younger in the UNG group than in the other groups, age-matched analysis also was conducted. Sexual function, evaluated by a self-administered questionnaire using the University of California Los Angeles-Prostate Cancer Index, was compared statistically among the three groups. RESULTS: In the age-matched analysis, the postoperative sexual function (SXF) score of the UNG group showed an intermediate level of recovery between those of the BNS and UNS groups at 12 months and reached the same level as the score at 12 months of the BNS group at 18 months postoperatively. The difference in the SXF score between the UNG and UNS groups began to appear after 6 months postoperatively and increased steadily with time. However, the background factors, such as the baseline SXF score, the usage rate of phosphodiesterase 5 inhibitors, and the rate of comorbidities were different between the UNG and UNS groups. CONCLUSIONS: The difference of the SXF score between the UNG and UNS groups increased with time after 6 months postoperatively. However, it might be difficult at present to attribute a better recovery of the SXF score to the nerve graft because of the difference in the background factors between the groups.
