Pankreas Cerrahisi Sonrası Pankreatik Fistül Yönetimi
Özet
Postoperatif pankreatik fistül (POPF), pankreas cerrahisi sonrası karşılaşılan en kritik komplikasyonlardan biri olup batın içi abse, sepsis ve masif hemoraji gibi ciddi sonuçlara yol açabilmektedir. Uluslararası Pankreas Cerrahisi Çalışma Grubu (ISGPS) kriterlerine göre POPF, ameliyat sonrası 3. gün veya sonrasında dren amilaz düzeyinin normalin üç katını aşması olarak tanımlanır ve klinik şiddetine göre Biyokimyasal Kaçak, Grade B ve Grade C olarak sınıflandırılır. Yüksek beden kitle indeksi, yumuşak pankreas dokusu ve dar Wirsung kanalı önemli risk faktörleri arasında yer almaktadır. Tedavi yaklaşımı; konservatif yöntemler, perkütan drenaj ve kontrol altına alınamayan durumlarda re-laparotomiye kadar uzanan disiplinler arası bir "adım adım" (step-up) sürecidir. Distal pankreatektomide fistül oranları daha yüksek olsa da anastomoz içermediği için cerrahi revizyon ihtiyacı daha düşüktür; buna karşın santral pankreatektomi iki anastomoz yüzeyi nedeniyle daha risklidir. Sonuç olarak, multidisipliner bir yönetim ve operasyonların yüksek volümlü merkezlerde gerçekleştirilmesi cerrahi başarıyı artırmaktadır.
Postoperative pancreatic fistula (POPF) is one of the most critical complications encountered after pancreatic surgery, potentially leading to severe outcomes such as intra-abdominal abscess, sepsis, and massive hemorrhage. According to the International Study Group of Pancreatic Surgery (ISGPS) criteria, POPF is defined as a drain amylase level exceeding three times the normal limit on or after the third postoperative day and is classified as Biochemical Leak, Grade B, or Grade C based on clinical severity. Significant risk factors include high body mass index, soft pancreatic tissue, and a narrow Wirsung duct. The management approach is an interdisciplinary "step-up" process ranging from conservative methods and percutaneous drainage to re-laparotomy in uncontrollable cases. While fistula rates are higher in distal pancreatectomy, the need for surgical revision is lower as it does not involve an anastomosis; conversely, central pancreatectomy is riskier due to two anastomotic surfaces. Consequently, multidisciplinary management and performing operations in high-volume centers enhance surgical success.
