Pankreatitte Minimal İnvaziv Tedaviler
Özet
Akut pankreatit, lokal komplikasyonlara ve inflamatuar süreçlere yol açabilen, interstisyel ödematöz ve nekrotizan olmak üzere iki tipe ayrılan klinik bir tablodur. Hastaların yaklaşık %5-10'unda görülen nekrotizan pankreatit, yüksek mortalite riski taşımakta ve multidisipliner bir yaklaşım gerektirmektedir. Geleneksel olarak uygulanan erken cerrahi nekrozektomi yöntemleri yüksek komplikasyon ve ölüm oranlarıyla (%11-39) ilişkilendirildiğinden, günümüzde daha az invaziv teknikler ön plana çıkmıştır. Bu kapsamda geliştirilen ve altın standart olarak kabul edilen "step-up" yaklaşımı, sepsisi kontrol altına almak adına öncelikle perkütan veya endoskopik drenaj uygulanmasını, klinik iyileşme sağlanamadığı durumlarda ise minimal invaziv retroperitoneal nekrozektomiye (VARD) geçilmesini öngörmektedir. PANTER çalışması, step-up modelinin açık cerrahiye kıyasla yoğun bakım ihtiyacını, fıtık riskini, yeni diyabet gelişimini ve tedavi maliyetlerini önemli ölçüde azalttığını ortaya koymuştur. Ek olarak, perkütan drenajın tek başına vakaların yaklaşık %35-47'sinde başarı sağladığı, endoskopik transgastrik yaklaşımların ise yüksek kavite rezolüsyonu sunduğu saptanmıştır. Sonuç olarak, akut pankreatit yönetiminde erken cerrahi debridmanlardan kaçınılması, endikasyon halinde müdahalelerin en az 4 hafta ertelenmesi ve minimal invaziv basamaklı protokollerin tercih edilmesi güncel literatürün temel tavsiyesidir.
Acute pancreatitis is an inflammatory process classified into interstitial edematous and necrotizing types, which can lead to significant local complications. Necrotizing pancreatitis, affecting 5-10% of patients, carries a substantial risk of mortality and demands a highly coordinated, multidisciplinary treatment strategy. Traditional early open surgical necrosectomy has historically been linked to high complication and mortality rates ranging from 11% to 39%, leading to a major paradigm shift toward less invasive options. The current gold standard, known as the "step-up approach," prioritizes controlling the source of infection through initial percutaneous or endoscopic drainage, reserving minimal invasive retroperitoneal necrosectomy (VARD) only if clinical improvement is not achieved. The landmark PANTER trial demonstrated that this step-up model significantly reduces ICU admissions, incisional hernias, new-onset diabetes, and overall treatment costs compared to open debridement. Research indicates that percutaneous catheter drainage alone achieves definitive success in 35-47% of cases, while endoscopic transgastric drainage offers excellent cavity resolution. Ultimately, contemporary medical guidelines strongly recommend avoiding early surgical debridement, delaying mandatory interventions for at least 4 weeks, and utilizing progressive, minimally invasive step-up protocols to optimize patient outcomes.
