Öğe Abdominal actinomycosis simulating malignancy of the right colon(Digestive Diseases and Sciences, 2005) Işık, Burak; Aydın, Engin; Söğütlü, Gökhan; Ara, Cengiz; Yılmaz, Sezai; Kırımlıoğlu, VedatActinomycosis is a chronic, suppurative, and granulomatous disease caused by an anaerobic or microaerophilic gram-positive bacterium, Actinomyces israelii, manifesting itself as fistula, sinus, inflammatory pseudotumor, or abscess formation. The cervicofacial region (50 to 65%) accounts for the majority of the cases followed by abdomen (20%) (1–5). Abdominal infection mostly involves the cecal area and can simulate malignant tumor on clinical and radiological examinations (1, 4, 6, 7). The diagnosis is almost always ascertained after surgery and histopathological examination of the specimen. The purpose of this report is to emphasize the possibility of encountering an abdominal mass related to actinomycosis in emergency cases and the benefit of limited surgical procedure.Öğe Abdominal actinomycosis simulating malignancy of the right colon(Digestive Diseases and Sciences, 2005) Işık, Burak; Aydın, Engin; Söğütlü, Gökhan; Ara, Cengiz; Yılmaz, Sezai; Kırımlıoğlu, VedatActinomycosis is a chronic, suppurative, and granulomatous disease caused by an anaerobic or microaerophilic gram-positive bacterium, Actinomyces israelii, manifesting itself as fistula, sinus, inflammatory pseudotumor, or abscess formation.

This study spesifically addressed the problem of emergency ABO-I LTx in critically ill adult patients having acute liver failure or severely decompensated end stage liver disease. Methodology: This series included 16 patients, of which 10 underwent ABO-I LD LTx and 6 patients underwent 7 ABO-I DD LTx. Two patients underwent ABO-compatible LD LT before ABO-I DD LT, because of hepatic artery thrombosis. Multiple sessions of plasmapheresis were used to reduce isoaglutinin titres to 1/16 or below before and after the transplantation. Splenectomy was carried out after the graft reperfusion in the last 7 cases. In the first 9 patients splenic artery ligation was performed. Data were prospectively collected and retrospectively analysed. Results: The follow-up period ranged from 1 to 38 months. The mean follw-up period was 10.37 months. Median age of patients was 50 years (17-63 years). The MELD scores ranged from 17 to 30 (median 22.5). Median survival of patients was 9 months and mean survival was 19.5 months. Hospital mortality consisted of 3 patients (18.7 %). Two patients died due to small for size graft syndrome and cerebrovascular bleeding respectively. Hepatic artery thrombosis developed in 3 patients. Two of them died at postoperative 4th and 9th months. Third patient is stil living with hepatic necrosis problem. Conclusion: ABO-I LTx remains an important and unavoidable therapeutic option in adult patients with acute or acute-on-chronic liver failure awaiting an emergency procedure and in the context of living donor liver transplantation. This option should be offered to all patients in cases of immediate need for an allograft without the possibility to allocate a blood group compatible liver graft.Öğe ABO incompatible liver transplantation in acute and acute on chronic liver failure(Hepatogastroenterology, 2013) Yılmaz, Sezai; Aydın, Cemalettin; Işık, Burak; Kayaalp, Cüneyt; Yılmaz, Mehmet; Ara, Cengiz; Kutlu, Ramazan; Bayındır, Yaşar; Ersan, VeyselAbstract BACKGROUND/AIMS: ABO-incompatible (ABO-I) liver transplantation (LTx) may be mandatory in urgent conditions such as acute liver failure (ALF) or acute-on-chronic liver failure (ACLF) when deceased donor (DD) is unavailable or living donor (LD) selection is limited.

Gereç ve Yöntem: Ocak 1997-Aralık 2000 tarihleri arasında akut taşlı kolesistit nedeniyle ameliyat edilen 28 olgu incelemeye tabi tutuldu. Olguların 19’u kadın 9’u erkek olup en genç hasta 28 ve en yaşlı hasta ise 75 yaşında olmak üzere ortalama yaş 53.5 ±13.7 idi.Beyaz küre, yaş, cinsiyet, alkalen fosfataz ve akut kolesistitin şidetine göre konversiyon oranları karşılaştırıldı. Bulgular: 28 hastanın 10’unda konversiyon (açık kolesistektomi) gerçekleşti (%35.7). Beyaz küre yüksekliği (>18000/uL) ve kolesistitin şiddeti konversiyon için anlamlı olarak bulundu (sırayla p=0.011 ve p=0.0007). Erkek cinsiyet, hastanın yaşının 60’ın üzerinde olması ve alkalen fosfataz yüksekliğinin, konversiyonla ilişkisi ortaya konulamadı (sırayla p=0.677, p=0.432 ve p=0.601). Hiçbir hastada postoperatif major komp likasyon gözlenmezken uzamış ateş ve yara enfeksiyonu gibi minor komplikasyonlar konversiyon grubunda laparoskopi grubuna göre daha fazla gözlendi. Konversiyon grubunda, hastanede kalış ve operasyon süresi anlamlı olarak daha uzundu (Sırayla; p<0.001 ve p=0.021). Sonuç: Akut kolesistitli hastaların coğunda laparaskopik girişimin güvenle yapılabileceği görüşündeyiz. Ancak, hasta seçimi üzerinde durulması gereken konudur ve beyaz küre yüksekliği (>18.000 u/L) ve kolesititin şiddeti konversiyonla ilişkilidir.Öğe Anastomoz kaçaklarının engellenmesinde kullanılmak üzere doğal bileşeni biouyumlu polimerik yapıştırıcıların sentezi ve uygulaması(2013) Ateş, Burhan; Ara, Cengiz; Parlakpınar, Hakan; Köytepe, Süleyman; Vardı, Nigar; Denkbaş, Emir Baki; Yılmaz, Baki[Abstract Not Available]Öğe Bare stent implantation in iatrogenic dissecting pseudoaneurysm of the superior mesenteric artery(Cardiovasc Intervent Radiol, 2007) Kutlu, Ramazan; Ara, Cengiz; Saraç, KayaLatrogenic arterial dissection leading to the development of dissecting pseudoaneurysms of the superior mesenteric artery (SMA) is a rare complication of angiography. Surgical and endovascular treatment options exist for this important condition. We report a case of bare stent implantation in dissecting pseudoaneurysm of the SMA that developed after angiography in a patient with acute mesenteric ischemia. Although it is rarely published, iatrogenic arterial dissection causing pseudoaneurysm can occur after diagnostic and interventional angiography. Bare stent implantation in dissecting pseudoaneurysm of the SMA could be an advantageous endovascular treatment option in selected cases due its to potential preservation of important side branches of the SMA.Öğe Beneficial Effect of Caffeic Acid Phenethyl Ester (CAPE) on Hepatocyte Damage Induced by Bile Duct Ligation: An Electron Microscopic Examination(Taylor & Francis Inc, 2010) Esrefoglu, Mukaddes; Ara, CengizRecently the authors have reported the potent beneficial effect of caffeic acid phenethyl ester (CAPE) on cholestatic oxidative liver injury induced by acute bile ligation in Swiss albino rats. Herein, they report the ultrastructural hepatocellular alterations induced by acute bile duct ligation and the effect of CAPE administration on these alterations. Bile duct ligation resulted in many degenerative changes, such as vacuolization, mitochondrial degeneration, endoplasmic reticulum dilatation, and lysosome accumulation within the cytoplasm of hepatocytes. Mitochondrial degeneration was also observed within the cytoplasm of the cells of biliary ductular epithelium.
