Gastroscopy (1)

1. What is Gastroscopy?

Gastroscopy is the use of endoscope, going into upper digestive system through the patient's mouth, esophagus, into the stomach, duodenum and jejunum. The doctor can observe the internal status in order to carry out the examination, diagnosis and appropriate treatment.

2. What is the function of Gastroscopy?

By the use of endoscope, doctor can check the internal conditions of the upper digestive system (esophagus, stomach, duodenum and jejunum). If necessary, the doctor can perform some treatments as follow:

    Biopsy collection for lab test
    Removal of foreign body
    Varicose veins treatment
    Laser treatment
    Pyloroplasty for Pyloric Stenosis
    Polypectomy
    Inner lining hemostasis


3. Before Gastroscopy, what do I need to prepare and pay attention?

Points to note for patients before gastroscopy:

Sign the consent form for receiving gastroscopy examination or treatment after well understanding with doctor’s explanation.
   
Do not eat within 6 hours before the examination in order to avoid aspiration when inducing vomiting, and provide a clear vision view for gastroscopy.
   
Follow doctor’s instruction for arrangement of taking the chronic illness medication (diabetes, hypertension, or drug allergy).
   
Follow the date, time and place for meeting the appointment of the gastroscopy.

治療複雜腹部主動脈瘤

我們的身體滿布血管，當中最大的要算主動脈，位於人體的胸腔及腹部，不停地隨看心跳擴張收縮，運送血液由心臟到全身各器官。若主動脈壁不正常地擴張便會形成主動脈瘤，較常出現於腹部主動脈。其風險是一旦主動脈瘤破裂，便會大量出血，病人會於短時間內失血致死。

因此，大多數患者會接受微創血管腔内手術醫治腹部主動脈瘤，但一些形狀較複雜的血管瘤未必適合用微創手術而需接受開放式手術，開放式手術創傷性較大，一些身體狀況較差的患者未必能承受。幸而，現時有些鞏固儀器能於微創血管控內手術時使用，令一些本來不能用微創手術又不適合開放式手術的患者受惠。

腹部主動脈瘤患者多為年長人士，男性及有家族史的人患病風險亦較高。現時，醫學界仍未真正了解其成因，但主要與血管退化有關。年齡增長，動脈粥樣硬化及主動脈壁產生過多的溶解酵素等都會令血管壁失去彈性而慢慢擴張，最終血管壁會抵受不住正常血壓而破裂。

大部分腹部主動脈瘤都沒有徵狀，多數於接受超聲波或電腦掃描檢查時偶然發現，若出現腹部及背部痛是則可能是爆破先兆，應立即求醫。


現年60多歲的何先生(化名)曾患有肺癆及接受「心臟通波仔」手術，所以肺功能及整體身體狀況都較差。他於身體檢查時意外發現一個頗大的腹部主動脈瘤，且有爆裂風險。理論上他要盡快接受手術，但由於其血管瘤形狀不能穩固放置支架，故不適合微創手術，他身體狀況又接受不了開刀手術，進退兩難。

幸好在新技術配合下，如今也有辦法。醫生首先在血管内植入支架，即使血管瘤的形状不理想，支架不穩固，但新穎的血管腔內鞏固裝置，就好像螺絲釘般把支架固定於血管壁，何先生於術後3日已出院。
