    Kolon kanseri ve adrenal lenfoma birlikteliği
    (DergiPark, 2019) Kapan, Metin; İpek, Turgut; Başoğlu, İrfan; Seçkin, Fatih Göksel
    Metastatik kolon kanserinde metastaz yerine ve sayısına göre primer cerrahi ya da neoadjuvant tedavi seçenekler arasındadır. Karaciğer metastazlarında senkron cerrahi ya da iki aşamalı cerrahi yapılabilir. Adrenal metastaz kolorektal kanserde genellikle yaygın hastalık belirtecidir. Bu yazıda ön tanı olarak karaciğer ve adrenal metastazı olan obstrüksiyona neden olmuş inen kolon kanserinde cerrahi sonrası adrenal lenfoma tanısı alan hasta sunulmuştur.

    Omental calcified fibrous tumor with symptoms after COVID-19 infection
    (OXFORD UNIV, 2022) Topcu, Feyza Sonmez; Ipek, Turgut; Kapan, Metin; Yilmaz, Serpil; Ensaroğlu, Fatih
    Calcified fibrous tumor (CFT) is a rare benign tumor of mesenchymal origin. Between 1988 and 2019, a total of 272 CFT cases were reported. CFTs can be seen in all anatomical regions with soft tissue. Histologically, mononuclear inflammatory infiltrates and the presence of psammomatous calcification in dense hyalinized collagen are characteristic features of the tumor. Currently, if the tumor is located in only one focus, surgical removal is recommended. Although CFT is a benign tumor, it may cause complications. Diagnosis is often difficult due to the confusion of tumor findings with many diseases. We present a patient with CFT, whose omental lesions were detected on abdominal computed tomography, and the diagnosis was confirmed by histopathological examination.

    Sequential analysis of single-center experience of living donor kidney transplants with several vascular anastomosis techniques
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2021) Kundaktepe, Berrin Papila; Durgun, Ali Vedat; Göksoy, Ertuğrul; Pekmezci, Salih; Kapan, Metin; Sarıbeyoğlu, Kaya; Velidedeoğlu, Mehmet; Eliçevik, Mehmet
    Background and aim: Vascular variations of grafts are handled with various reconstruction techniques in renal transplantation. We aimed to analyze the effects of these reconstruction techniques and sites on patient/graft outcomes. Materials and methods: Renal transplantation cases at the Transplantation Unit of the General Surgery Department, Istanbul University Cerrahpasa Medical Faculty between January 1st, 2000 and December 31st, 2012 were analyzed retrospectively. Postoperative duplex ultrasound results, urea-creatinine reduction rates, and complications were evaluated. Results: There were 228 living-donor transplantation cases evaluated. For single-renal-artery living-donor transplantations, there were 45 end-to-side external iliac artery, 15 end-to-side internal iliac artery, 152 end-to-end internal iliac artery, and 3 end-to-side common iliac artery anastomoses performed. In cases with double-arteries, 3 had end-to-side external iliac artery anastomoses, and 10 had end to-end internal iliac artery anastomoses. No statistically significant differences were found between reconstruction techniques with regard to complications or urea-creatinine reduction rates. Conclusion: Internal, external, and common iliac arteries can be safely used for anastomoses. The presence of more than one renal artery creates no short or long-term problems when a side-to-side anastomosis is initially performed.
