Item Acute Appendicitis After Diaphragmatic Hernia After Pediatric Liver Transplant(Başkent Üniversitesi, 2011-02) Aktas, Sema; Haberal, Mehmet; Bilezikci, Banu; Coskun, Mehmet; Ozcay, Figen; Karakayali, Hamdi; Sevmis, SinasiMultiple complications in liver transplant have been described in the literature. However, appendicitis and diaphragmatic hernia have rarely been reported after solid-organ transplant. The clinical presentation of appendicitis is similar to that of nontransplant patients, but complications are more frequent, because the majority of the patients did not have leukocytosis. Diaphragmatic hernia can present with a variety of atypical clinical symptoms. In this report, 1 patient who developed a diaphragmatic hernia and appendicitis after liver transplant is presented. A 2-year-old boy with end-stage liver cirrhosis owing to progressive familial intrahepatic cholestasis type-2 received a living-donor liver transplant. The posttransplant course was complicated. The diagnosis of diaphragmatic hernia was confirmed by thoracoabdominal computed tomography, and we decided to proceed with surgical repair. The patient had evidence of perforation, and the appendix was removed. After repositioning the intestine in the abdomen, a chest tube was placed, and the defect repaired with interrupted polypropylene sutures. The patient recovered after surgery without untoward sequelae.Item Acute Gastric Variceal Bleeding During Orthotopic Liver Transplant(Başkent Üniversitesi, 2010-09) Shapiro, David P.; Aniskevich, Stephen; Shine, Timothy S.We present a case of intraoperative gastric variceal bleeding during liver transplant. After an uneventful induction and surgical dissection, our patient developed hemodynamic instability during the anhepatic phase. We believe that an increase in portal pressures, owing to clamping of the portal system, led to spontaneous variceal rupture; however, placement of an oral gastric tube or transesophageal echocardiography probe may have contributed to this also. After intraoperative banding, the patient was stabilized and surgery proceeded uneventfully. The patient had no long-term sequelae. Anesthesiologists involved in the care of patients with end-stage liver disease should be aware of this infrequent intraoperative complication and be prepared to treat it appropriately.Item Alemtuzumab Preconditioning Allows Steroid-calcineurin Inhibitor-free Regimen in Live-donor Kidney Transplant(Başkent Üniversitesi, 2011-10) Refaie, Ayman F.; Ghoneim, Mohamed A.; Kamal, Ahmed I.; Sheashaa, Hussein A.; Ismail, Amani M.; Mahmoud, Khaled M.Objectives: This prospective study was designed to develop a steroid and calcineurin inhibitor-free regimen for kidney transplants using alemtuzumab. Materials and Methods: A single dose of alemtuzumab (30 mg) was given preoperatively. Phase 1: Twenty-one patients were randomized into 2 groups; the tacrolimus (n=11) and the sirolimus groups (n=10). Steroids were given for 5 days. Azathioprine (1 mg/kg) was added when white blood cells ≥ 4000 cells/cm3. Mean follow-up was 48 ± 2.8 and 48.2 ± 1.6 months for the tacrolimus and sirolimus groups. Phase 2: Twenty patients were included and the study design was modified. Tacrolimus was given for 2 months, and was replaced by sirolimus thereafter. The mean follow-up was 28.3 ± 2.1 months. Results: Phase 1: Acute rejection episodes were encountered in 5 patients of the tacrolimus versus 2 cases in the sirolimus group (P = .44). Antibody-mediated rejection was diagnosed in 2 recipients in each group. Four patients were switched from sirolimus to tacrolimus owing to resistant rejection, significant proteinuria, persistent thrombocytopenia, lymphocele, and urinary leakage. One patient was shifted from tacrolimus to sirolimus owing to Kaposi sarcoma. Glomerular filtration rate was significantly higher in the sirolimus group. Currently, 14 patients (8 tacrolimus, and 6 sirolimus) are steroid-free. One patient died from the tacrolimus group owing to fulminant hepatitis. Two grafts were lost in the sirolimus group versus 1 graft in the tacrolimus group. Phase 2: Five patients developed successfully treated borderline changes with no antibody-mediated rejection. Mean serum creatinine was 114.9 ± 17.7 µmol/L. Currently, 17 patients are steroid-free and 15 of them are calcineurin inhibitor-free as well. In this phase, only 1 patient died with a functioning graft. Conclusions: This clinical trial provides a good insight into a potentially effective steroid and calcineurin inhibitor-free protocol with the use of alemtuzumab induction in combination with sirolimus.Item Analysis of Right Lobe Living-Liver Donor Complications: A Single Center Experience(Başkent Üniversitesi, 2011-02) Yaprak, Onur; Tokat, Yaman; Yuzer, Yildiray; Tabendeh, Babek; Demirbas, B. Tolga; Dayangac, MuratObjectives: Living-donor liver transplant provides an alternative source of organ to patients with end-stage liver disease. This study sought to determine and classify the donor morbidities after right lobe donor hepatectomy in a single center. Materials and Methods: One-hundred eighty-one right lobe living-donor hepatectomy were performed in our center between January 2004 and December 2009. Of the 181 donors, 104 donors were men and 77 donors were women. Mean age of the donors was 38 years (range, 18-63 years). The mean follow-up was 33.3 months (range, 3-66 months). Complications after the operation were stratified according to the Clavien classification. Results: Eighty-one complications occurred in 73 of the 181 donors (40.3%). The most common complication was wound infection, which was seen in 14 of 181 donors (7.7%). Biliary complications were seen in 4.4% of donors. There was no postoperative mortality. Also, grade 4 complications, which are life-threatening, did not occur. Blood transfusion were not required during the operation. The incidence of reoperation was 1.6% in all donors. Conclusions: Living-donor liver transplant ensures a new graft to patients with end-stage liver disease. Donor morbidity is one of the realities of the donor hepatectomy procedure. Because the donors are healthy individuals, the aim of the process must be to eliminate the donor mortality while decreasing the complication rates.Item Aspergillus Fumigatus Spondylodiskitis in Renal Transplant Patient: Voriconazole Experience(Başkent Üniversitesi, 2011-08) Ersoy, Alparslan; Ener, Beyza; Akalin, Halis; Oruc Koc, Aysegul; Dizdar, Oguzhan SitkiThe incidence of invasive aspergillosis has increased after solid organ transplant. However, aspergillus osteomyelitis in vertebrae is rare. We report a case of aspergillus spondylodiskitis after pulmonary aspergillosis in a renal transplant recipient. He was treated by antifungal therapy and surgical intervention. The transplantist should be alert for a diagnosis of aspergillus spondylodiskitis in recipients who developed back pain after aspergillosis infection in other sites.Item Bellek(2022) Başkent ÜniversitesiItem Bellek(2017) Başkent ÜniversitesiItem Bellek(2015) Başkent ÜniversitesiItem Bellek(2012) Başkent ÜniversitesiItem Bellek(2013) Başkent ÜniversitesiItem Bellek(2011) Başkent ÜniversitesiItem Bellek(2024) Başkent ÜniversitesiItem Bellek(2019) Başkent ÜniversitesiItem Bellek(2018) Başkent ÜniversitesiItem Bellek(2014) Başkent ÜniversitesiItem Bellek(2023) Başkent ÜniversitesiItem Bellek(2016) Başkent ÜniversitesiItem Bilateral Transversus Abdominis Plane Block for Managing Pain After a Pancreas Transplant(Başkent Üniversitesi, 2011-08) Aniskevich, Stephen; Torp, Klaus D.; Clendenen, Steven R.The authors report the first clinical application of a bilateral transversus abdominis plane block for treating pain after a pancreas transplant. In this case, a 36-year-old chronic opioid user presented postoperatively with severe incisional pain following a pancreas transplant. The pain was not ameliorated with opioids and was successfully treated with the administration of bilateral transversus abdominis plane blocks with 0.5% ropivicaine. Pain relief lasted for 6 hours.Item Bülten(2017) Başkent ÜniversitesiItem Bülten(2023) Başkent Üniversitesi
