Pankreas Kistik Neoplazileri ve Cerrahi Yaklaşım
Özet
Pankreas kistik neoplazileri (PKN), gelişmiş radyolojik yöntemlerin kullanımıyla daha sık saptanan ve tüm pankreas kistlerinin %15-20’sini oluşturan lezyonlardır. En sık karşılaşılan tipleri Seröz Kistik Neoplaziler (SKN), Müsinöz Kistik Neoplaziler (MKN) ve İntraduktal Papiller Müsinöz Neoplazilerdir (İPMN). Genellikle tesadüfen saptanan bu tümörlerin ayırıcı tanısı, tedavi protokollerinin belirlenmesinde kritik öneme sahiptir. SKN’ler çoğunlukla iyi huylu bir profil çizerken ve asemptomatik olgularda cerrahi gerektirmezken; MKN ve İPMN’ler premalign veya malign özellik taşımaktadır. Cerrahi yaklaşım, lezyonların malign transformasyonundan önce rezeke edilmesini amaçlar. Bu kapsamda kitle lokalizasyonuna göre dalak koruyucu distal pankreatektomi, segmental rezeksiyon veya Whipple prosedürü gibi onkolojik rezeksiyonlar uygulanır. Cerrahi kararlarında Sendai ve Fukuoka kılavuzları yol gösterici olup, invaziv süreç başlamadan yapılan müdahaleler mükemmel sağkalım sonuçları sunmaktadır. Bu nedenle premalign kistlerin yönetimi, pankreas cerrahisinde deneyimli merkezlerde kişiselleştirilmiş protokollerle yapılmalıdır.
Pancreatic cystic neoplasms (PCNs) are increasingly detected due to advanced radiologic imaging, accounting for 15-20% of all pancreatic cystic lesions. The most common types include Serous Cystic Neoplasms (SCNs), Mucinous Cystic Neoplasms (MCNs), and Intraductal Papillary Mucinous Neoplasms (IPMNs). Differential diagnosis of these often incidentally discovered tumors is crucial for determining management strategies. While SCNs generally exhibit a benign profile and require conservative management in asymptomatic patients, MCNs and IPMNs carry significant premalignant or malignant potential. Surgical treatment aims at timely resection of premalignant lesions before malignant transformation occurs. Depending on anatomical localization, standard oncological resections such as spleen-preserving distal pancreatectomy, segmental resection, or the Whipple procedure are performed. International guidelines, including Sendai and Fukuoka criteria, guide surgical decision-making, and resection prior to invasive disease yields excellent survival rates. Consequently, managing these premalignant cysts requires personalized protocols in high-volume pancreas surgery centers.
