Publication Open Access Prognostic Impact of the Metastatic Lymph Node Ratio on Survival in Gastric Cancer(SPRINGER INDIA, 2016-03) GÜNAL, ÖMER; Attaallah, Wafi; Uprak, Kivilcim; Gunal, Omer; Yegen, CumhurResearch on the prognostic value of lymph node ratio (LNR) in gastric cancer (GC) remains limited and controversial results were obtained. In this study, we aimed to evaluate whether LNR was an independent prognostic factor for gastric carcinoma. A retrospective review of a database of gastric cancer patients was performed to determine the effect of the LNR on the overall survival (OS) and the disease-free survival (DFS). Of the total 135 patients with gastric cancer who underwent resection between March 2012 and December 2013, 44 patients with non metastatic gastric cancer were eligible for analysis. Survival curves were estimated using the Kaplan-Meier method. Cox regression analyses, after adjustments for potential confounders, were used to evaluate the relationship between the LNR and survival. According to the cutoff point 0.37 (37 %), the one-year OS rate for LNR <= 37 % was significantly better than that for LNR > 37 % (91.3 % and 61.9 %, respectively, P = 0.02). The one-year DFS for LNR <= 37 % was significantly better than that for LNR > 37 % (91.3 % and 66.7 %, respectively, P = 0.027). In stratified and multivariate analyses adjusted for age, gender, histology and tumor status, a higher LNR was associated with high pN stage and so associated with worse OS and DFS. Thus, the LNR 37% as a cutoff point was found not to be an independent factor for predicting the one-year OS or DFS in patients with non-metastatic GC. The LNR is a prognostic factor in GC. However, no single cut-off value was determined as an independent prognostic factor.Publication Metadata only PARKİNSON HASTALIĞININ TEDAVİSİNDE SÜREKLİ LEVODOPA- KARBİDOPA BAĞIRSAK JELİ (LCIG) İNFÜZYONU İÇİN PERKÜTAN ENDOSKOPİK TRANSGASTRİK JEJUNOSTOMİ (PEG-J) TÜPÜ TAKILMASI TEKNİĞİ VE TEK MERKEZ SONUÇLARIMIZ(2021-10-30) AKMERCAN, TAYFUN; UPRAK, TEVFİK KIVILCIM; COŞKUN, MÜMİN; GÜNAL, ÖMER; GÜNAL, DİLEK; AKMERCAN T., UPRAK T.

K. , ERDİM A., Karatas S. A. , GÜNAL Ö.; Marmara Üniversitesi, Tıp Fakültesi, Cerrahi Tıp Bilimleri BölümüReduced excess weight loss (EWL) or regain is a worrying problem after metabolic surgery. Factors attainable from the resected specimen that can predict this outcome are investigated. We retrospectively analyzed 64 patients who had undergone laparoscopic sleeve gastrectomy. We collected demographic data, preoperative gastric emptying measurements, volume, expansion capacity, and 6-dimensional measurements of sleeve gastrectomy specimens. Correlations between EWL, body mass index levels, and gastric specimen measurements related to gastric remnant dimensions were also scrutinized. We found a significant correlation between the gastric specimen and remnant gastric volume, the resection line length in the gastric specimen, and 12th-month EWL%. Antrum expansibility was significantly increased in patients with weight regain. There was also a negative correlation between weight loss and age at postoperative first and third years. Sleeve resection line measurement and resected antrum diameter measurements can be used to predict weight loss, especially in the first year postoperatively.Publication Open Access Letter to the editor-radiographic measurement of gastric remnant volume after laparoscopic sleeve gastrectomy: Assessment of reproducibility and correlation with weight loss(2022-07-01) UPRAK, TEVFİK KIVILCIM; GÜNAL, ÖMER; Ergenc M., UPRAK T.

K., COŞKUN M., UĞURLU M. Ü., GÜNAL Ö., CİNGİ A., YEGEN Ş. C.Objective: In obesity surgery, laparoscopic sleeve gastrectomy (LSG) is a frequently applied method. However, there are certain complications. Leakage is one of the most serious complications after surgery, causing postoperative morbidity and sometimes mortality. There is no consensus about management of leaks after LSG. In our study, we aimed to present our experience on the management of LSG leaks. Patients and Methods: Patients who underwent LSG between 2010-2017 in a tertiary university hospital were analyzed retrospectively. Demographic characteristics, endoscopic and surgical interventions, morbidity, and mortality rates of patients diagnosed with LSG leak were analyzed from prospectively recorded data. Results: Leak was observed in 11 (2.15%) of a total of 510 LSG patients. Six (54%) patients were diagnosed as acute and 5 were early leaks. Stent was applied to most of the patients (72%) with or without surgical exploration. The average length of stay in hospital was 21 days. Mortality was observed in 2 patients. Conclusions: Consequently, leakage after LSG is a complication that requires multimodal therapy. Surgical treatment combined with endoscopic intervention may increase success.
