为何建议进行此手术

本手术为通过开放切口切除手部或腕部肌腱鞘内充满液体的囊袋。您的外科医生提出此建议,很可能是因为您存在持续性疼痛或僵硬,且经抽吸等非手术治疗后未见改善。尽管约 40% 的腕部腱鞘囊肿可在六年内自行缩小,但大多数在针头引流后会复发。手术可显著降低囊肿复发的几率,复发率约为 10%。

该手术采用单一传统切口切除囊袋,以防止其再次充盈。此方法旨在缓解您的疼痛并恢复手部的全部功能。虽然手术会留下瘢痕并伴随一定风险,但当其他治疗失败时,它是防止问题复发的最有效方法。

手术前

请在手术前禁食六小时,并遵照外科医生的建议停用任何抗凝药物。安排专人开车送您回家,并携带一份您目前所有用药的清单。您可能需要进行X光、MRI或血液检查,以确认诊断并评估您的健康状况。您的外科医生将通过一个位于囊肿上方的小切口进行开放手术。该方法可完整切除腱鞘囊肿并充分引流,以降低其复发的可能性。请穿着舒适的衣物,并准备好接受快速的麻醉评估。大多数患者认为这些准备工作简单明了。

手术当天

您将抵达医院,并与您的外科医生和麻醉师会面。在前往手术室之前,他们将评估您的健康状况,并回答您可能有的任何问题。本手术将在全身麻醉下进行。手术期间您将完全处于睡眠状态。部分患者可能还会接受区域神经阻滞以缓解术后疼痛;麻醉师将根据您的具体情况在手术当天决定。

您的外科医生将在需要治疗的区域做一个切口,以切除腱鞘囊肿。随着麻醉效果的消退,您将在复苏室苏醒。您可能会感到困倦或昏沉,医疗团队将密切监测您的状况,直到您准备好回家或返回病房。

手术内容

您的外科医生将在腱鞘囊肿所在位置做一个切口。这是一种开放入路,意味着医生将直接通过这个单一切口进行操作,而不是使用小型的关节镜摄像头。医生将仔细切除囊肿以及任何允许液体从关节或腱鞘渗漏的连接组织。

如果囊肿压迫神经,您的外科医生将轻柔地将神经从周围组织中游离出来,以恢复其功能。医生还可能同时处理任何潜在的关节问题,以帮助预防囊肿复发。一旦囊肿被切除且区域清理完毕,您的外科医生将用缝线缝合切口。

该手术旨在一次性移除充满液体的囊袋并解决问题的根源。手术的确切时长取决于您病例的具体位置和复杂程度。

术后

您将在复苏室苏醒。您的外科医生将管理您的疼痛,以确保您舒适。您的切口处会有敷料覆盖,您可能需要佩戴简单的夹板或支具以提供支撑。这通常作为日间手术进行,因此您预计当天即可回家,尽管偶尔患者可能需要过夜。您必须在最初的24小时内有人陪同。您可以立即轻柔地活动手指和手部。您的外科医生将提供关于在家如何护理伤口的具体指导。

恢复

在开放手术后,您可能会在切口周围感到一些疼痛和肿胀。这是身体愈合过程中的正常现象。您的外科医生可能会建议您抬高患处并使用冰袋来缓解不适。您可能会注意到关节僵硬,这在组织修复期间是预期的。

您需要遵循特定的伤口护理和运动指导。您的外科医生可能会推荐轻柔的锻炼以保持周围肌肉活跃,同时不对修复部位造成压力。您可能会在短期内佩戴夹板或绷带以保护手术部位。随着肿胀消退和活动能力恢复,您可以逐渐恢复日常活动,如进食或书写。一旦您的外科医生允许,并且您能够在不疼痛的情况下握住方向盘,您就知道可以开车了。

您的恢复过程是独特的。有些人会很快感觉好转,而其他人则需要更长时间才能恢复全部力量。您的外科医生和物理治疗师将指导您何时增加活动量。信任您的身体并遵循他们的建议,以确保获得最佳效果。

可能发生的问题

大多数患者恢复良好,但偶尔也会出现并发症。您的外科医生和医疗团队会密切监测您,以便尽早发现任何问题。

您可能会注意到肿块在相同位置复发。这称为复发。即使进行了囊肿切除手术,也可能发生这种情况。如果肿胀再次出现,请告知您的外科医生,以便他们进行检查。

有时,切口周围的区域会变红、发热或非常压痛。您可能会感到剧烈疼痛,且普通止痛药无法缓解。这些迹象可能意味着感染正在发生。如果出现这些变化,请立即致电诊所。

在极少数情况下,您可能会感到手部活动或感觉突然发生变化。您可能会注意到伤口附近出现无力、麻木或奇怪的弹响声。这可能是由于附近的神经或血管受到影响所致。请在下次复诊时立即提出此问题,如果突然发生,请前往急诊科。

本页的并发症表格列出了典型的发生率,如果您需要了解具体情况,可查阅该表格。

何时联系我们

如果您出现发热、切口处红肿加重或渗出,请立即联系我们。若出现突发剧烈疼痛、新发麻木或手部活动障碍,请立即联系您的外科医生。如发现小腿肿胀或呼吸困难,请前往急诊室。这些症状可能提示感染或血栓形成。若出现上述任何情况,您的外科医生希望尽快为您诊治。

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

Section 2 -- Scope.

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable.
