研究者发现采用新的方法使手术切口比通常方法减少一半, 切除病变甲状腺效果一样好。 根据一项发表在在6月刊喉镜“Laryngoscope”杂志上的研究结果表明, 甲状腺切除术有望改进, 可以采用创伤更小, 既安全, 又使病人伤口恢复快, 容貌更佳的方式进行。

研究者对在2003 年9月和2004 年5月之间, 在美国佐治亚医疗中心退伍军人事务医疗中心医疗学院(奥古斯塔)所进行的44 名病人癌变或良性甲状腺切除术结果进行观察比较后所得出的结论。

这是一种非常简便而直接的手术, 对熟练的外科大夫很容易掌握。手术运用多种技术手段,减少头颈部的切口:从原来的3-4英寸减少到1-2英寸。新法照样可以切除部分或全部桃子般大的甲状腺体。

Dr. David J Terris, Porubsky 是该中心耳鼻喉科学MCG 部门的教授和系主任,头脖部手术专家和论文主要作者。他介绍说 "我们先用自动牵开器让甲状腺体曝露, 然后我们借用刚好可伸进小切口的显微放大镜和腹腔镜等其他器械 使随后的手术能通过影像屏幕进行, Dr. Terris说 由于手术切口小,他可以在手术当天就送病人回家。

通常要触及和切除甲状腺, 多数耳鼻喉医师(otolaryngologists)会在病人颈基部做水平切口, 也就是业内称为"横向子宫颈领"切开法, 移开肌肉和周边解剖组织于甲状腺旁。 这种方法,对部分有早先手术或有高度肿大的甲状腺患者依然是最佳的选择。

但Dr. Terris 认为:在研究中的多数患者- 44 名患者中的65% -可以受益于更小, 更直接的方法。 他注意到, 尽管通过更小的空间(切口)施行手术会使工作量和手术时间大约增加20-30%, 但那不是他的患者所担心的事。

最小创伤性的切除法包括更小的切口, 必要的血管绑扎, 然后以所谓Sofferman 技术-切开带状肌肉- 直接触及甲状腺。 外科医生使用插入的微型摄象机和内窥镜进行手术。 切除完后, 先修复带状肌肉, 再用医疗粘胶封闭切口。 由于这样的手术组织创伤减少, 使手术后创口引流也大为减少。 患者也许在手术当天回家或在医院度过一夜即可, 与以往手术需要至少二到三天的医院逗留观察明显方便和节省开资。 事实上没有一个经过最小创伤切除法的患者需要再通过经典手术做善后处理, 只有一位患者在切口处出现较厚的伤疤。

"这一方法真是太好了," Dr. Terris说: "它给我们怎么处理这些患者的手法带来完全是革命性的改变。 更重要的事是, 我们通常在年轻妇女中做这样的切除术。 她们最关心术后对她们外表形象的变化。"女性比男性更容易患良性甲状腺结节和甲状腺癌; 44 名被调查的患者就有31位是妇女, Dr. Terris 认为 女性患者的现实需求促使他探索创伤性更小的手术改进。"Dr. Terris 和他的同事在论文中还强调:”这种方法是对现代内分泌外科医生实践的改良和适宜的补充。”,

New approach to thyroid surgery reduces incision size

An incision about half the length used for traditional surgery works just as well in removing diseased thyroids, researchers have found.

This minimally invasive approach is safe, likely speeds wound healing and has a superior cosmetic result, according to findings published in the June issue of Laryngoscope.
The study looked at 44 patients with cancerous or benign thyroid disease who had surgery between September 2003 and May 2004 at Medical College of Georgia Medical Center or the Veterans Affairs Medical Center in Augusta.
"This is a very straightforward approach in skilled hands that allows us to use smaller incisions while still safely identifying important structures in the area, which are the nerves to the voice box and the parathyroid glands," says Dr. David J. Terris, Porubsky Professor and chair of the MCG Department of Otolaryngology - Head and Neck Surgery and lead author on the study.
This approach incorporates various techniques to reduce the typical incision size across the base of the neck - from about three to four inches to one to two inches - while still enabling removal of all or part of the peach-sized gland that controls metabolism. Growths on this gland can cause jitters and weight loss.

"We use retractors to get exposure and use telescopes and other laparoscopic instruments that can fit through a small incision then we work off the video screen," says Dr. Terris. "I send many patients home the day of surgery because it's so much less invasive."
To access the thyroid, most otolaryngologists make a horizontal incision at the base of neck, called a transverse cervical collar incision, move the muscles and dissect out the thyroid. This approach remains the best option for some patients who have had previous surgery or have an extremely enlarged thyroid.
But most patients - 65 percent of the 44 patients in the study - likely can benefit from a smaller, more direct approach, Dr. Terris says. He notes that working through the smaller space increases surgery time about 20-30 percent, but that has not been a deterrent for his patients.

The minimally invasive approach includes a smaller incision, ligating blood vessels as needed, then cutting through the strap muscles - called the Sofferman technique - to directly access the thyroid. Surgeons use tiny video cameras and endoscopes to work through the incision. Afterward, the strap muscles are repaired and the incision closed with medical-grade glue. Reduced tissue trauma means less chance of postoperative drainage from the site. Patients may go home the same day or spend one night in the hospital compared to two to three days with the older technique.
None of the patients selected for the minimally invasive approach had to be converted to conventional thyroidectomy. One of the minimally invasive patients developed a mildly thick scar that responded to treatment.

"It works great," says Dr. Terris. "It's really revolutionized how we manage these patients. The biggest thing is that we are doing this typically on young women. They tend to care the most about what their incision is going to look like." Women are more likely than men to develop nodules and thyroid cancer; 31 of the 44 study patients were women, Dr. Terris says. That reality helped inspire his pursuit of less invasive options. "This approach is evolving but is an appropriate addition to the practice of the modern endocrine surgeon," Dr. Terris and his colleagues write.

这种手术我们医院也开展了,现将内窥镜辅助下甲状腺手术的内容拿出来与大家一起分享
内镜甲状腺手术在国际上最早做的是Gagner M 1996 (France)人甲状旁腺手术 和 人单侧甲状腺叶切除术 CSG Hiischer 1997 (France)GHC Yeung 1997 (HongKong) 。

翻译得很好,但业内应该没有"横向子宫颈领"这种说法,因为这里说的是头颈不是宫颈。
