Pankreas Cerrahisi Sonrası Biliyer Komplikasyonlar ve Yönetimi
Özet
Pankreas cerrahisi sonrası gelişen biliyer komplikasyonlar, cerrahi tekniklerdeki ilerlemelere rağmen postoperatif dönemde önemli bir morbidite ve mortalite nedenidir. En sık karşılaşılan komplikasyonlar safra kaçağı, biliyer striktür, kolanjit ve geçici sarılık (akut anastomoz ödemi) olarak öne çıkmaktadır. Yapılan çalışmalarda, hem safra kaçağı hem de striktür gelişimi için en önemli bağımsız risk faktörünün ana safra kanalı çapının 5 mm'den küçük olması gösterilmiştir. Erken dönemde saptanan safra kaçakları çoğunlukla konservatif takip veya perkütan drenaj gibi girişimsel radyoloji yöntemleriyle başarıyla tedavi edilirken; peritonit, septik şok veya yüksek debili kaçak varlığında acil re-operasyon ve anastomoz revizyonu kaçınılmaz olmaktadır. Geç dönem komplikasyonlarından olan biliyer striktür ve kolanjit yönetiminde ise MRCP veya kolanjiyografi ile kesin tanı konulduktan sonra öncelikle perkütan transhepatik biliyer drenaj (PTK), balon dilatasyonu ve stentleme gibi nonoperatif yöntemler tercih edilmektedir. Girişimsel işlemlerin yetersiz kaldığı durumlarda gerilimsiz bir Roux-en-Y hepatikojejunostomi cerrahisi altın standarttır. Sürecin cerrahi, endoskopik ve radyolojik ekiplerce multidisipliner yönetilmesi, hastanede yatış sürelerini ve maliyetleri düşürmede kritik rol oynamaktadır.
Biliary complications following pancreatic surgery remain a major source of postoperative morbidity and mortality despite recent advancements in surgical techniques. The most frequently encountered complications include bile leaks, biliary strictures, cholangitis, and transient jaundice caused by acute anastomotic edema. Clinical data indicates that a main bile duct diameter of less than 5 mm is the primary independent predisposing factor for both leaks and strictures. Early-onset bile leaks are typically managed via conservative monitoring or minimally invasive interventional radiology methods such as percutaneous drainage; however, surgical re-exploration and anastomotic revision are mandatory in patients presenting with peritonitis, septic shock, or high-output drainage. Late complications like biliary strictures and cholangitis require accurate diagnostic imaging via MRCP or cholangiography, with initial treatment prioritizing non-operative interventions including percutaneous transhepatic biliary drainage (PTCD), balloon dilation, and stenting. When these interventional modalities fail to yield successful outcomes, surgical reconstruction with a tension-free Roux-en-Y hepaticojejunostomy stands as the gold standard treatment. Managing these cases through a multidisciplinary approach involving surgical, endoscopic, and radiological teams is crucial to preventing unnecessary procedural repetitions and minimizing prolonged hospitalization and healthcare costs.
