Anastomosis leakage is a major complication of rectal surgery. The aim of this study was to identify risk factors for anastomotic leakage after low anterior resection (LAR) in rectal cancer patients and study its impact on long-term prognosis and disease-free survival and overall survival in rectal cancer patients. Consecutive patients who underwent rectal(More)
Fistula is a representative devastating complication in Crohn's patients due to refractory to conventional therapy and high recurrence. In our phase I clinical trial, adipose tissue-derived stem cells (ASCs) demonstrated their safety and therapeutic potential for healing fistulae associated with Crohn's disease. This study was carried out to evaluate the(More)
Because palpating colonic tumors during laparoscopy is impossible, the precise location of a tumor must be identified before operation. The aim of this study was to evaluate the accuracy of various diagnostic methods that are used to localize colorectal tumors and to propose an adequate localization protocol for laparoscopic colorectal surgery. A total of(More)
Approximately 20% of patients with colorectal cancer are initially diagnosed with stage IV. The majority has non-curative metastases, and their chances of survival are pitiful. This study evaluated the prognostic factors of survival and the access to the effective treatment in accordance with patients. We retrospectively analyzed 503 patients for(More)
Performing a restaging work-up with magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG PET/CT) can provide information about the effects that are related to preoperative concurrent chemoradiotherapy (CCRT). The purpose of the present study was to investigate the accuracy of MRI and 18F-FDG(More)
BACKGROUND/AIMS Anatomical hepatectomy for small hepatocellular carcinomas (HCCs) is widely preferred but evidence concerning its benefits is inadequate. The aim of this study was to determine whether patient outcome is influenced by the method used to treat small single HCCs. METHODOLOGY An analysis was performed on 168 patients who underwent curative(More)
Liver recipients who have antibodies to hepatitis B core antigen (anti-HBc) or received an anti-HBc positive liver graft are at risk of acquiring de novo hepatitis B infection so a life long prophylaxis is required. A post-transplant vaccination against hepatitis B virus (HBV) can offer a better alternative than either hepatitis B hyperimmune globulin(More)
BACKGROUND The development of living donor liver transplantation has stimulated discussion about the expansion of tumor burden limits for patients with hepatocellular carcinoma (HCC). Although serum alphafetoprotein (AFP) level is an important predictor of tumor recurrence, it is not included in the existing selection criteria for HCC in transplantation. (More)
A previous phase II clinical trial of adipose-derived stem cell (ASC) therapy for fistulae associated with Crohn's disease, a devastating condition with a high recurrence rate, demonstrated safety and therapeutic potential with a 1-year sustained response. In the present study, 41 of the 43 phase II trial patients were followed for an additional year,(More)
BACKGROUND Several surgical and non-surgical therapeutic modalities have been used for the treatment of hepatocellular carcinoma (HCC). There have been several studies comparing hepatic resection (HR) and percutaneous ethanol injection (PEI) for the treatment of HCC. However, there is still disagreement about the best treatment modality. METHODS From 130(More)
