Objective: The optimal method for closure of the appendix stump in laparoscopic appendectomy is stil controversial. There have been many defined methods for this aim. Here were trospectively compare the closure of appendix stump with intra corporeal knot tying and hem-o-lok clip. Material and Method: Ninty-two case sunder went to laparoscopic appendectomy in Elazig Medical Park Hospital from January 2013 to June 2014 was retrospectively screened. Age, gender, hospital stay, operation time, whether complicated appendicitis complicated appendicitis, complications and management of complications were noted. Patients were divided into two groups, Group 1 (hem-o-lok clip) and Group 2 (intra corporeal knot tying). Datas were compared between two groups. Results: Ninty-twopatients (43 male/49 female) were screened. Mean age was 35.1 (15-77) years. Mean operation time was 28.8 minutes (20-50), mean hospital stay was 1.25 (0-5) days. Operation time was significantly shorter in group 1 (p<0.001), both in uncomplicated (p<0.001) and complicated (p=0.046) cases. Although hem-o-lok group had a low hospital stay and postoperative complication rate, the difference between two groups was not statistically significant. Conclusion: Hem-o-lok clip is a simple and a safe tool for closure of appendiceal stum with low operation time. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to analyze the predictive value of preoperative laboratory findings in acute appendicitis in geriatric patients aged >65 years., Methods: We enrolled a total of 4121 patients. A retrospective evaluation of the demographic features was made using preoperative laboratory values such as the white blood cell (WBC), neutrophil, and lymphocyte counts; platelet counts; the mean platelet volume and bilirubin values; and postoperative pathological data of the patients from the electronic file system. The neutrophil-to-WBC and neutrophil-to-lymphocyte ratios were calculated. Patients were divided into two groups, as geriatric (≥65 years old, n=140) and non-geriatric (<65 years old, n=3981)., Results: The white blood cell and lymphocyte counts, and the neutrophil-to-WBC ratio, were significantly higher in the non-geriatric group (p<0.001, p=0.013, and p=0.021, respectively). The neutrophil and platelet counts were higher in the non-geriatric group, but this difference was not statistically significant (p=0.073 and p=0.072, respectively). A higher neutrophil-to-lymphocyte ratio was determined in the geriatric group, but the difference was not significant (p=0.176). According to the optimumal cutoff value of 12.11×10 3 /µL for WBC, specificity and sensitivity values of 65.4% and 57.9% were calculated, respectively; the AUC value was 0.632±0.024 (p<0.001). A receiver operating characteristic (ROC) analysis was used to calculate the optimum cutoff values of neutrophil-to-WBC ratio, lymphocyte, and the mean platelet volume, but the diagnostic accuracy of these tests was inadequate with an AUC of <0.6., Conclusion: WBC values >12.11×10 3 /µL were predictive of acute appendicitis in geriatric patients. The other parameters were not predictive, and further studies are required., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (Copyright: © 2019 by Istanbul Northern Anatolian Association of Public Hospitals.)

Purpose: The objective of this study was to preoperatively evaluate blood platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) for their prognostic value in patients with colorectal cancer (CRC)., Methods: We retrospectively reviewed 347 patients who underwent colorectal surgery for CRC in the Istanbul Education and Research Hospital and the Antalya Education and Research Hospital. The prognostic value of preoperative PLR, NLR, and other clinical and laboratory parameters was assessed with univariate and multivariate analysis., Results: Median overall survival (OS) was 61.8 months [95% CI for hazard ratio (HR) 46.24-77.14]. Significant parameters in univariate analysis, which were the preoperative levels of carcinoembryonic antigen (CEA) (p=0.055), albumin (p=0.003), hemoglobin (p=0.012), PLR (p=0.004), and NLR (p=0.054) were assessed by multivariate analysis which showed that only albumin retained its significance (p=0.008). Median OS was 70.1 vs 44.8 months with PLR ? 180 vs PLR > 180 (log rank; p=0.005). Median OS was "Not reached" (NR) vs 43.5 months with NLR ? 3 vs NLR > 3 (log rank; p=0.012)., Conclusions: This study showed that preoperative levels of CEA, albumin, PLR, and NLR have significant prognostic value for patients with CRC.

Background: The detection of true localization of the tumour are crucial to driving the proper treatment algorithm in distally-located colorectal cancers (CRCs). The performance of four methods; colonoscopy, computed tomography (CT), magnetic resonance imaging (MRI), and fluoro-deoxy-glucose-positron emission tomography scan (FDG/PET-CT), were evaluated to identify the localizations of distal colorectal malignancies according to the rectum, sigmoid colon and recto- sigmoid junction (RSJ)., Materials and Methods: Medical records of patients who underwent colorectal surgery for tumours located on the sigmoid colon, RSJ, or rectum were reviewed retrospectively., Methods: In total, 156 patients were included in the study. In terms of overall accuracy, colonoscopy, CT, MRI and FDG/PET-CT had similar accuracy rates, with 74%, 67%, 75%, and 74%, respectively. Colonoscopy was relatively less sensitive for rectosigmoid tumours (33%), while CT was less sensitive for rectal tumours (26%). MRI was less specific for tumours located on the rectum (33%)., Conclusions: It is crucial to correctly identify the location of distal colorectal tumours in order to plan accurate treatment strategies. Preoperative modalities, including colonoscopy, CT, MRI, and FDG/PET-CT, do not provide excellent accuracy for tumours of the distal colorectal tumours. To increase the success of these modalities; combined use could be more successful., Key Words: Colonoscopy, Computed tomography Distal colorectal cancer, Magnetic resonance imaging.

Addiction to synthetic cannabinoids (SCs) is a growing social and health problem worldwide. Chronic use of SCs may cause adverse effects in the gastrointestinal system. We describe a very rare case of acute gastric dilatation (AGD) and hepatic portal venous gas (HPVG), with findings of acute abdomen resulting from chronic use of a SC, Bonzai. AGD and HPVG were detected by computerized tomography examination. Patchy mucosal ischemia was seen in endoscopic examination. Despite the findings of an acute abdomen, a non-surgical approach with nasogastric decompression, antibiotic therapy, and close radiologic and endoscopic follow-up was preferred in the presented case. Clinical and radiologic findings decreased dramatically on the first day, and endoscopic findings gradually disappeared over 7 d. In conclusion, this case shows that chronic use of a SC may cause AGD and accompanying HPVG, which can be managed non-surgically despite the findings of acute abdomen.

Background/aims: Hepatic bleeding following abdominal trauma is a serious problem. The implementation of various materials and techniques have been attempted to prevent bleeding but a standard method is indefinite., Methodology: Hepatic resection model was performed on rats. The efficacy of hemostasis with Polidocanol and Tetradecyl Sulfate has been evaluated through the comparison of perioperative bleeding amount and preoperative and postoperative hematocrit levels in the 24th hour. Also, histopathologic changes on parenchyma have been compared at a microscopic level., Results: Preoperative and postoperative hematocrit differences were 5.50 +/- 0.59 in Polidocanol group and 10 +/- 1.30 in Tetradecyl Sulfate group (MW: 2, p < 0.001). Perioperative bleeding amounts were: 1.50 +/- 0.20 mL in the Polidocanol group, 3.50 +/- 0.15 mL in the Tetradecyl Sulfate group and 7.50 +/- 0.41 mL in the Control Group. Upon comparison of perioperative bleeding amounts: the Control Group values were very high in comparison to the Polidocanol group (p < 0.001) and the Tetradecyl Sulfate group values were higher than those of the Polidocanol group (p < 0.05)., Conclusions: Local sclerosing agents, especially Polidocanol, appear to be an effective alternative method in hemostasis of hepatic bleeding.
