Pankreas Cerrahisi Sonrası Biliyer Komplikasyonlar ve Yönetimi
Özet
Pankreatikoduodenektomi (PD), periampuller bölge tümörlerinde temel küratif tedavi yöntemi olsa da postoperatif dönemde ciddi biliyer komplikasyon riskleri barındırmaktadır. Bu çalışma, PD sonrası gelişen safra kaçakları ve hepatikojejunostomi (HJ) darlıkları ile bu süreçlerin yönetimini ele almaktadır. Safra kaçakları genellikle operasyon sonrası ilk hafta içinde dren içeriğinin bilirubin seviyesinin artmasıyla teşhis edilirken, HJ darlıkları daha geç dönemlerde kolanjit ve sarılık gibi semptomlarla ortaya çıkmaktadır. Yapılan araştırmalar, safra kanalı çapının 5 mm’den küçük olmasının hem kaçak hem de darlık gelişimi için kritik bir risk faktörü olduğunu göstermektedir. Günümüzde bu komplikasyonların yönetiminde cerrahi revizyonun yerini büyük ölçüde Perkutan Transhepatik Bilier Drenaj (PTBD) ve balon anjiyoplasti gibi minimal invaziv girişimsel radyolojik yöntemler almıştır. Özellikle HJ darlıklarının çoğunun benign fibrotik darlıklar olduğu ve malign nüks oranının düşük olduğu saptanmıştır. Sonuç olarak, erken teşhis ve girişimsel yöntemlerle sağlanan etkili drenaj, mortalite ve morbidite oranlarını düşürerek hasta yaşam kalitesini artırmaktadır.
Pancreaticoduodenectomy (PD) remains the primary curative treatment for periampullary tumors, yet it carries significant risks of postoperative biliary complications. This study evaluates bile leaks and hepaticojejunostomoy (HJ) strictures following PD, along with their management strategies. Bile leaks are typically diagnosed within the first postoperative week through increased bilirubin levels in drain output, whereas HJ strictures manifest later with symptoms such as cholangitis and jaundice. Research indicates that a bile duct diameter of less than 5 mm is a critical risk factor for both leaks and strictures. Currently, the management of these complications has largely shifted from surgical revision to minimal invasive interventional radiological methods, such as Percutaneous Transhepatic Biliary Drainage (PTBD) and balloon angioplasty. It has been observed that most HJ strictures are benign fibrotic narrowings, with low rates of malignant recurrence. Consequently, early diagnosis and effective drainage provided by interventional procedures reduce mortality and morbidity rates while improving the patient's quality of life.
