颈丛阻滞、硬膜外阻滞下甲状腺手术应激反应的比较

目的 :比较颈丛阻滞、硬膜外阻滞下甲状腺手术应激反应的大小。方法 :选择ASAⅠ～Ⅱ级 ,女性 ,甲状腺手术患者 30例 ,年龄 2 2～ 5 5岁 ,术前无呼吸、循环和内分泌疾病 ,随机分为颈丛阻滞组 (颈丛组 ) 15例 ,硬膜外阻滞组(硬膜外组 ) 15例 ;颈丛阻滞选用 0 .8%利多卡因和 0 .2 5 %布比卡因混合液 ,以C4一点法行双侧深浅丛阻滞 ;硬膜外阻滞选用 1.3%利多卡因和 0 .15 %丁卡因混合液 ,穿刺点选择C4～ 5或C5～ 6间隙 ,采用侧卧位直入法 ,并向头置管 3cm ;分别测定并记录麻醉前、麻醉后 2 0min、切皮、分上极、切腺体和术毕共六个时点的血糖、血压和心率的变化。结果 :两组病例各时点血糖均逐步上升 ,于分上极、切腺体和术毕血糖值与麻醉前比较有显著性差异 (P <0 .0 1) ;硬膜外组只在分上极时SBP与麻醉前比较有差异外 (P <0 .0 5 ) ,而颈丛组在分上极、切腺体时DBP与麻醉前比较有差异 (P <0 .0 5 ) ,SBP、MAP与麻醉前比较有显著性差异 (P <0 .0 1)。结论 :本研究表明颈丛阻滞、硬膜外阻滞均不能完全抑制甲状腺手术的应激反应 ,在稳定甲状腺手术循环功能方面硬膜外阻滞优于颈丛阻滞     

CT扫描及超声内镜术前评价进展期食管癌

目的比较胸部螺旋CT增强扫描及微探头超声内镜 (MPS)检查在评价进展期食管癌中的价值。方法 :32例进展期食管癌术前行CT扫描和MPS检查并与术后病理学比较。结果 :CT扫描能发现 84 .4 %的食管癌病灶 ,但不能准确诊断癌肿浸润深度 ,诊断纵隔结构受侵准确率 75 % ,发现区域淋巴结转移的敏感性90 .9% ,特异性 81.8% ,对纵隔内远处淋巴结转移诊断准确率 80 %。MPS检查能检出所有病例的进展期食管癌病灶 ,癌肿浸润深度诊断准确率 81.3% ,诊断纵隔结构受侵准确率 5 0 % ,诊断区域淋巴结转移敏感性81.8% ,特异性 72 .7% ,而对纵隔内远处转移的淋巴结均未能探及。结论 :CT扫描在评价进展期食管癌纵隔内结构受侵及远处淋巴结转移的意义较大。而MPS检查在判断癌肿管腔浸润深度的准确率较高。     

手术治疗125例分化性甲状腺癌的5年随访结果分析

目的：探讨甲状腺全切除术在治疗分化性甲状腺癌中的临床应用价值。方法：采用我院1988年1月～2001年5月甲状腺全切除术或甲状腺侧叶切除加峡部切除术治疗分化性甲状腺癌125例,对其手术并发症发生、局部复发、转移情况及术后5年生存率进行回顾性对比分析。结果：甲状腺全切除术术后并发症发生率高于甲状腺侧叶切除加峡部切除术组;局部复发、转移率低于侧叶切除加峡部切除术组;5年生存率两组无显著性差异。结论：甲状腺全切除术是治疗甲状腺癌有效的手术方式,但应掌握手术指征,改进、提高手术技术,减少并发症。     

Endocrine evaluation after endoscopic third ventriculostomy (ETV) in children

Objective Endoscopic third ventriculostomy (ETV) is a standard procedure for the treatment of obstructive hydrocephalus in children. Main part of the procedure is the perforation of the third ventricle floor (tuber cinereum). This structure is part of the hypothalamic–pituitary neuronal network of cerebral endocrine regulation. There are no systematic data available about the endocrine status after ETV in children. Materials and methods We examined 20 children who had undergone ETV. Examination included laboratory tests (adrenocorticotropic hormone, prolactin, insulin-like growth factor 1 [IGF-1], IGF-binding protein 3 [IGFBP-3], fT3, fT4, thyroid-stimulating hormone [TSH], serum osmolarity, electrolytes, glucose, urea, follicle-stimulating hormone [FSH] and luteinizing hormone [LH], and testosterone in selected patients), measurement of weight, height, and head circumference, and physical examination. The study was approved by the Ethics Committee of the Medical Faculty of Kiel University. Results In seven patients, prolactin was moderately elevated. One patient demonstrated a significantly increased prolactin (56.3 ng/ml). In all eight patients, this was the only laboratory value that was out of the normal range; all other parameters were normal. Three other patients showed one abnormal parameter (decrease in FSH and LH, increase in TSH, decrease in IGF-1 and IGFBP-3). In nine patients, weight or height was not within the 3rd to 97th centiles for age. Discussion and conclusion More patients than expected demonstrated endocrine laboratory abnormalities. However, there was no clinical relevance in any of the studied patients. It remains inconclusive whether ETV contributes to the abnormalities of prolactin levels or to other endocrine parameters in pediatric patients. Longitudinal studies are necessary to delineate the effect of ETV on endocrine regulation.

Surgical approach after failed enteryx injection for GERD.

OBJECTIVE: We report on 3 patients who underwent laparoscopic antireflux procedures for persistent symptoms of GERD after biopolymer injection. METHODS: Experienced laparoscopic surgeons completed all 3 procedures laparoscopically. In 2 patients, there was an extramural extravasation of the polymer outside and adherent to the esophageal wall. In these patients, a partial posterior fundoplication was used. The third patient, who had the polymer material deposits removed preoperatively by endoscopic mucosal resection, underwent a Nissen fundoplication. RESULTS: Postoperative recovery was uneventful in all cases. At follow-up of 6 to 12 months, all patients were symptom free, off medical therapy, and experiencing no dysphagia. CONCLUSION: Surgical therapy for patients after failed biopolymer injection is safe and effective. The choice of surgery may depend on whether the polymer mass can be removed preoperatively.
