Bu grupta mezenterik- omental kistler, enterik duplikasyonkistleri, meckel divertikülü/ omfalomezenterik duktus kistinden oluşmaktadır. Etyopatogenez,histopatoloji ve klinik özellikleri önemli ölçüde farklılık göstermektedir. Neoplastikkitleler ile ayırt etmede tanı zorluğuna neden olmaktadırlar. Bu çalışmada intrabdominalgastrointestinal sistem kaynaklı konjenital benign kistik lezyonların klinik, histopatolojiközellikleri ve ayırıcı tanıları birlikte incelenmiştir.Gereç ve Yöntem: Tıbbi Patoloji Anabilim Dalı arşivi taranarak mide, ince-kalınbarsak, mezenterik-omentumdan köken alan intrabdominal konjenital kistikkitleler çalışmaya alınmıştır. Bulgular: Nonneoplastik kistik 55 olgu retrospektifolarak incelendi. Yaş, cinsiyet, kliniksemptom, yerleşim yeri, histopatolojik bulgularına göre olgulardeğerlendirildi. En sık meckel divertikülü/ omfalomezenterik duktus kisti (n:34)mevcuttu. Daha sonra olguların görülme sıklığı sırasıyla; mezenterik-omentalkistleri (n:15) ve duplikasyon kistlerine (n:6) rastlandı. En sık görülen bulguabdominal kitle ve ağrıydı.Sonuç: Kistlerin kökeni ne olursa olsun spesifiktiplendirme, lezyonların histopatolojik olarak değerlendirmesiyle ( epitelesahip olup olmayışı, epitelin tipi) konmaktadır. Gastrointestinal sistemyerleşimli kistler ile ilgili en önemli sorun, bazen bu kistlerin neoplastiknitelik taşıyan kitlelerden veya parazite bağlı kistlerden ayırtedilememesidir. Fizik muayenede düzgün sınırlı kitle palpe edilen vegörüntüleme yöntemleriyle intraabdominal kistik kitle saptanan, karın ağrısıile başvuran hastalarda ayırıcı tanıda farklı gelişimsel nitelikler taşıyankistik kitleler göz önünde bulundurulmalıdır.

Inthis group, mesenteric-omental cysts, enteric duplication cysts, meckeldiverticulum / omphalomesenteric duct cyst. The etiopathogenesis,histopathology and clinical features differ significantly. They causediagnostic difficulties in differentiating with neoplastic masses. In thisstudy, the clinical, histopathological and differential diagnoses of thecongenital benign cystic lesions of the intrabdominal gastrointestinal tractwere investigated.Materialsand Methods: The archives of the Department of Medical Pathologywere reviewed and intrabdominal congenital cystic masses originating from thestomach, small-large intestine and mesenteric-omentum were included in thestudy.Result:Nonneoplastic cystic cases were retrospectively evaluated. Patients were evaluatedaccording to age, gender, clinical symptoms, location and histopathologicalfindings. The most common meckel diverticulum / omphalomesenteric duct cyst(n:34) was present. Then, the incidence of the cases were as follows;mesenteric-omental cysts (n:15) and duplication cysts (n:6). The most commonfinding was abdominal mass and pain.Conclusion:Specifically, regardless of the origin of cysts, specific typing is indicatedby histopathological evaluation of lesions (epithelium, type of epithelium).The most important problem with cysts located in the gastrointestinal tract isthat these cysts cannot be differentiated from neoplastic masses or parasites.In physical examination, cystic masses with different developmentalcharacteristics should be considered in the differential diagnosis of patientswith abdominal pain and intraabdominal cystic mass with palpated mass.
