Pankreas Cerrahisi Sonrası Pankreatik Fistül Yönetimi
Özet
Postoperatif pankreatik fistül (POPF), pankreas cerrahisi sonrasında en sık karşılaşılan ve klinisyenler için en fazla endişe uyandıran majör komplikasyonlardan biridir. Uluslararası Pankreas Cerrahisi Çalışma Grubu (ISGPS) standardizasyonuna göre POPF; Biyokimyasal Kaçak, Evre B ve Evre C olmak üzere üç grupta sınıflandırılır. Yüksek beden kitle indeksi, yumuşak pankreas dokusu ve dar Wirsung kanalı çapı gibi unsurlar bu komplikasyon için temel risk faktörleridir. Klinik seyir, basit bir karın ağrısından batın içi abse, sepsis ve masif kanamalara kadar geniş bir yelpazede değişkenlik gösterebilir. Tanı süreçlerinde bilgisayarlı tomografi ve dren amilaz takibi kritik rol oynar. POPF yönetiminin temelini sıvı-elektrolit dengesinin korunması, erken antibiyotik tedavisi ve enteral/parenteral beslenme desteği gibi konservatif yaklaşımlar oluşturur. Klinik olarak anlamlı fistüllerde, re-laparotomiye kıyasla daha düşük morbidite sunan bilgisayarlı tomografi veya ultrasonografi eşliğinde perkütan drenaj ilk aşamada tercih edilen minimal invaziv yöntemdir. Bu konservatif ve minimal invaziv tedavilerin yetersiz kaldığı, sepsisin geliştiği dirençli olgularda ise cerrahi revizyon, debridman veya total pankreatektomi gibi yüksek mortalite riski taşıyan re-operasyonlar kaçınılmaz hale gelmektedir.
Postoperative pancreatic fistula (POPF) remains one of the most frequent and challenging major complications encountered after pancreatic resections. According to the International Study Group of Pancreatic Surgery (ISGPS) classification, POPF is categorized into Biochemical Leak, Grade B, and Grade C based on clinical severity. High body mass index, soft pancreatic texture, and a small Wirsung duct diameter are identified as the primary risk factors. The clinical manifestation ranges from mild abdominal discomfort to intra-abdominal abscess, severe sepsis, and massive hemorrhage. Computed tomography and drain amylase levels are vital for accurate diagnosis and monitoring. The cornerstone of conservative management includes fluid resuscitation, empirical antibiotic therapy, and nutritional support. For clinically relevant fistulas, minimally invasive percutaneous or endoscopic drainage is preferred over re-laparotomy due to its significantly lower surgical trauma and higher success rates. However, in refractory cases where interventional methods fail and life-threatening sepsis develops, aggressive surgical re-interventions—ranging from operative debridement to total pancreatectomy—are required as a last resort, despite carrying high mortality rates.
