Chylothorax is defined as abnormal accumulation of lymphatic fluid in the pleural space. Chylothorax is a rare case and generally occurs after thoracic and cardiac procedures. Chylothorax causes respiratory and nutritional problems and a significant mortality rate. Good knowledge of the underlying pathophysiology enables early diagnosis and prevention of the chronic complications related to immunodeficiency and malnutrition. Octreotide is a long-acting somatostatin analog that can reduce lymphatic fluid production and has been used as a new strategy in the treatment of chylothorax. In gastrointestinal tract, somatostatin and octreotide act on somatostatin receptors to reduce intestinal blood flow by vasoconstriction of the splanchnic vessels; decrease gastrointestinal motility; and inhibit gastric, pancreatic, and biliary secretions, thus reducing intestinal fat absorption and lymphatic flow in the thoracic duct. Octreotide is generally considered to be safe, with only occasional side effects. The side effects of octreotide are mainly related to its vasoconstrictive and antisecretory actions. The general consensus is for conservative management with octreotide to be instituted for 1 week before consideration of surgery. In case of either high flow rate chylothorax, especially after oesophageal surgery, or failure of conservative treatment with octreotide, operation is indicated.

Şilotoraksın tedavisinde oktreotidin kullanımı

Öz

Şilotoraks plevral aralıkta lenfatik sıvının anormal birikimi olarak tanımlanır. Şilotoraks nadir bir durumdur ve genellikle torasik veya kardiyak işlemler sonrası ortaya çıkar. Şilotoraks solunumsal ve nütrisyonel problemlere ve anlamlı mortaliteye neden olur. Alttaki patofizyolojinin iyi bilinmesi erken tanıyı sağlar ve immün yetmezlik ve malnütrisyona bağlı kronik komplikasyonları önler. Octreotid lenfatik sıvı üretimini azaltan uzun etkili bir somatostatin analoğudur. Şilotoraks tedavisinde yeni bir yöntem olarak kullanılmaktadır. Gastrointestinal sistemde somatostatin ve octreotid, somatostatin reseptörleri üzerinden active olarak splenik damarların vazokonstrüksiyonu ile intestinal kan akımını azaltır. Ayrıca gastrointestinal motiliteyi, gastrik, pankreatik ve bilier sekresyonları azaltarak intestinal yağ emilimini azaltır ve sonuçta duktus torasikusta lenfatik akım azalır. Octreotid genel olarak güvenli kullanıma ve nadiren yan etkiye sahiptir. Octreotidin yan etkileri temel olarak vazokonstriktif ve sekresyonları inhibe edici etkisine bağlıdır. Genel konsensus cerrahiden önce bir hafta octreotid ile konservatif yaklaşımdır. Özellikle özefagus cerrahisi sonrası, şilotoraksın yüksek akımına sahip olduğu veya octreotid ile konservatif tedavinin yetersiz olduğu vakalarda operasyon endikedir.
