這次剛好care兩個病患都是要做Fontan TCPC的
一個是DORV+PA+PDA
另一個是TA+ASD(POD)+VSD+PDA
CHD
Fontan手術Total cavopulmonary connection (TCPC)
Fontan本質是一個緩和性(palliative)而非治癒性(curative)的手術。
Indication:
三尖瓣閉鎖(Tricupsid atresia),肺動脈瓣閉鎖(Pulmonary atresia),DORV(Double outlet of right ventricle)
現在的Fontan術式為 Total cavopulmonary connection (TCPC) ,分為兩個階段,分別將上腔靜脈和下腔靜脈接到肺動脈。
上下腔靜脈血壓會升高,血流速度會變慢甚至停滯、逆流,造成淋巴系統和肝水腫(hepatic congestion),進一步引發凝血因子異常和慢性血管(微)栓塞。
使preload減少和afterload增加,長期對剩餘的單一心室產生性質上的改變,如hypertrophy。另外,肺部血流的阻抗也會增加。

GI吳教授查房
Cecum在spine左邊:考慮malrotation嬰兒排便正常:一天兩三次到兩周一次
Rare Case: Jejunum以下全部aganglionic
Congenital aganglionic megacolon (Hirschsprung disease)
Ileus
intestinal obstruction機械性腸阻塞
high-pitch hyperactive bowel sound,典型的腸阻塞可聽到所謂 metallic sound
adynamic ileus(neurogenic ileus; paralytic ileus)無動性腸阻塞(functional disorder)
可能原因
1. Postoperative (by far the most common)
2. Peritonitis
3. Reflex (the retroperitoneal syndrome)
4. Spinal injuries
5. Metabolic disturbances (uremia, diabetic coma, myxoedema and potassium depletion)
6. Ganglion-blocking agents
最重要的發現是腸聲(bowel sound)減少或消失,這是和一般腸阻塞鑑別診斷最好的方法。
Intestinal pseudo obstruction; acute colonic pseudo-obstruction; Ogilvie's syndrome; acute megacolon
absence of any mechanical obstruction
It is a type of megacolon
