Chyloperitoneum after Abdominal Aortic Aneurysmectomy: Report of a Case

腹主動脈瘤切除後併發乳糜腹:病例報告

摘要


雖然腹部主動脈與乳糜池的解剖位置非常接近,腹部主動脈術後所造成的乳糜腹卻非常少見。一般認爲,在進行腹部主動脈手術時,或多或少都會造成後腹腔淋巴系統之損傷,甚至會破壞乳糜池。但在手術後禁食的期間,乳糜的流量將大爲減少,這使得受到破壞的淋巴管可藉機癒合修復,因此臨床上就較少術後乳糜腹的病例。我們在此報告一位67歲男性糖尿病患,因罹患菌病性腹主動脈瘤(mycotic aortic aneurysm)而接受主動脈瘤切除合併人工血管置換術。病人在術後五日開始進食,進食後,産生腹脹及大量乳糜樣腹水自引流管排出的現象,經檢驗確定流出腹水爲乳糜。我們給予並指導病人食用低脂高蛋白質及高中鏈脂肪酸含量之飲食。改變飲食之後,乳糜樣腹水即明顯減少。在手術5個月後,我們將患者身上所有引流管拔除,同時恢復其正常飲食。其後在門診追蹤期間,該病患無腹脹或其他任何不適之症狀,成功地治愈了腹部主動脈手術引起之乳糜腹。目前認爲,因手術引起之乳糜腹水,其治療方法以保守治療爲優先選擇:給予病人食用低脂高蛋白質及高中鏈脂肪酸含量之飲食,有時尚須合併短暫之全靜脈營養。大部分的患者在接受保守治療後都能痊癒。若保守治療無法解決乳糜腹水之現象及症狀,可考慮手術結紮淋巴瘻管或置放腹腔-靜脈引流管。

The anatomical relationship between the aorta and cisterna chili is close, but chyloperitoneum seldom causes a problem after abdominal aortic surgery. The treatment includes operative and conservative methods. We present a 67-year-old male patient, who underwent abdominal aortic aneurysmectomy and reconstruction with a bifurcated graft because of the infected aortic aneurysm. The operation was complicated with chyloperitoneum, but conservative management with low-fat, high- protein and medium-chain triglyceride diet proved successful 5 months after the operation. The patient did not receive total parenteral nutrition or reoperation, and was able to tolerate normal ordinary diet during the follow-up period.
