Methods: From December 2002 to May 2003, 28 patients with a mean age of 28 years (range from 20 to 45 years) were selected and given video assisted endoscopic thyroidectomy by the breast approach. The subcutaneous space in the breast area and the subplatysmal space in the neck were bluntly dissociated through a 10 mm incision between the nipples, and CO 2 was insufflated at 6 8 kban to create the operative space. Three trocars were inserted in the mammary regions, and dissection of the thyroid and division of the thyroid vessels and parenchyma were performed endoscopically using an ultrasonically activated scalpel. The recurrent laryngeal nerve, the superior laryngeal nerve, and the parathyroid glands were preserved properly. Results: Among the patients, 3 were mass resections, 17 subtotal lobectomies, 2 total lobectomies, and 6 subtotal lobectomies plus contralateral mass resections. The mean operative time was (87.1±26.0) min; the mean estimated blood loss was (47.9±19.6) ml; and the mean postoperative hospital stay was (3.4±0.7) d. The drainage tubes were pulled out at 36 60 h postoperatively. There were no conversions to open surgery or complications. No scars left in the neck, and the patients were satisfied with the postoperative appearance. Conclusion: Video assisted endoscopic thyroidectomy using a breast approach and low pressure subcutaneous CO 2 insufflation is a feasible and safe procedure, which results in satisfactory appearance. We believe that video assisted endoscopic thyroidectomy by such approach will play a role in the future.展开更多

Permanent complications in Group B were significantly higher than those in Group A(1320.6%vs 45.6%,P=0.009).Con- clusion:RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.展开更多
OBJECTIVE To investigate the clinical value in a comparison between intraoperative exposure and non-exposure of the recurrent laryngeal nerve （RLN） of the neck during left neck esophagogastric anastomosis following ...OBJECTIVE To investigate the clinical value in a comparison between intraoperative exposure and non-exposure of the recurrent laryngeal nerve （RLN） of the neck during left neck esophagogastric anastomosis following resection of carcinomas of the middle and inferior-segment esophagus. METHODS From January 2003 to April 2009, 237 patients were selected to undergo resection of esophageal squamous carcinoma via posteroexternal incision of the left chest plus gastroesophageal anastomosis at the left neck incision. The 237 cases were divided into 2 groups： 115 of the total cases were in group A （the study group）, cases of resections with neck RLN exposure. Of the patients in this group, 64 were male and 51 female, with a mean age of 49 ranging from 31 to 73 years. Another 122 cases were in group B （the control group）, cases of resections without neck RLN exposure. In this group, 51 of the patients were male and 71 female, with a mean age of 45 ranging from 33 to 75 years. In the 2 groups, there were 9 cases in total with symptoms induced by RLN injury. RESULTS Hoarseness, choking cough when drinking, and difficult expectoration were found in 1 of the cases （1/115） in group A （0.087%）, while there were 8 cases （8/122） presenting with these symptoms in group B （6.5%）. There is statistical signi.cance in the di.erences of RLN injury between the 2 groups （P 〈 0.05）. CONCLUSION Analysis of study cases of esophageal carcinoma resection with left-neck esophagogastric anastomosis in the 2 groups indicated that the exposure of the RLN in group A resulted in an obviously lower rate of neck RLN injury after the surgery, compared to group B, where the RLN was not exposed. Exposure can lead to the avoidance of complications induced by RLN injury, such as dysarthria and choking cough when eating. As a result, satisfactory expectoration, which would diminish the incidence of pulmonary complications, can be reached allowing the patients to recover as early as possible. The results of our study suggest that the exposure of the RLN during the left -neck esophagogastric anastomosis has signi.cant clinical value, and that this approach can be recommended with con.dence.展开更多

文摘目的评价经喉罩插管和经鼻气管插管两种人工气道模式对靶控输注（target controlled infusion，TCI）异丙酚瑞芬太尼麻醉下大脑皮质功能区手术术中唤醒试验效果的影响。方法择期行大脑皮质功能区手术的患者20例，将致病灶位于语言中枢以及同时位于语言中枢和运动中枢的患者称为喉罩组（I组），将致病灶位于运动中枢的患者称为气管插管组（Ⅱ组）。两组患者的麻醉诱导均采用异丙酚瑞芬太尼TCt，I组至意识消失后行喉罩插管，Ⅱ组待患者进入深睡眠状态后，经鼻气管插管，两组患者的麻醉维持均采用异丙酚瑞芬太尼TCI，按相同的脑电双频指数（BIS）值来调整血药靶浓度。术中行唤醒试验，记录唤醒时间。记录麻醉诱导即刻（T1）、插管后10min（T2）、患者能按指令活动时（T3）的平均动脉压（MAP）、心率（HR）、呼气末二氧化碳分压（P ET CO2）的变化，同时记录两组患者唤醒期间的相关并发症。结果所有患者均完成唤醒试验，唤醒时间分别为（16．9±2．4）min（I组）、（15．7±1．8）min（II组），两组患者唤醒时间差异无统计学意义（P〉0．05）；唤醒期间Ⅱ组恶心、呕吐，高碳酸血症，脑膨胀的发生率（0％）显著低于I组（20％）（P〈0．05）。结论对病灶位于大脑皮质运动中枢的患者，尽量使用TCI异丙酚端芬太尼麻醉下经鼻气管插管的人工通气模式，可以提高术中唤醒试验的效果。
