Background/Aims: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been accepted as a reliable tool indiagnosing and staging intra-abdominal tumors. In this study, we aimed to investigate the performance of EUS-FNA in theevaluation of liver masses and its impact on patient management and procedure-related complications retrospectively. Methods: Data of patients who underwent EUS-FNA biopsies due to liver masses between November 2017 and July 2018 wereretrieved retrospectively. Biopsies were performed using 22-G needles. The demographics, EUS-FNA results, sensitivity andspecificity of the procedure, negative predictive value, positive predictive value, and specimen sufficiency rates were assessed. Results: A total of 25 patients (10 females) were included in the study. The mean age was 62.73±15.2 years. The mean size of themasses was 34.50±16.04 mm. The technical success rate was 88%. During the EUS-FNA procedure, each patient had only one passwith 94.45% of aspirate sufficiency rate and 86.3% of biopsy sufficiency rate. The diagnostic accuracy rate was 86.3%. There were nocomplications. Conclusions: For the evaluation of liver masses, EUS-FNA using a 22-G needle with even one pass had high aspiration and biopsysuccess rates accompanied with high diagnostic accuracy rates.

Background/Aims: Altered anatomy is a challenge in endoscopic retrograde cholangiopancreatography (ERCP) for patients withBillroth II anastomosis. In this study, we investigated the overall success and role of endoscopist experience. Methods: Data of patients who underwent ERCP between 2014 and 2018 after a previous Billroth II operation were retrievedretrospectively from 2 tertiary ERCP centers. The procedures were performed by 2 endoscopists with different levels of experience. Clinical success was defined as extraction of the stone, placement of a stent through a malignant stricture, and clinical and laboratoryimprovements in patients. Results: Seventy-five patients were included. The technical success rate was 83% for the experienced endoscopist and 75% for theinexperienced endoscopist (p=0.46). The mean (±standard deviation) procedure time was 23.8±5.7 min for the experienced endoscopistand 40.68±6.07 min for the inexperienced endoscopist (p<0.001). In total, 3 perforations (4%) were found. The rate of afferent loopperforation was 6.25% (1/16) for the inexperienced endoscopist and 0% (0/59) for the experienced endoscopist (p=0.053). Conclusions: ERCP in patients who had undergone Billroth II gastrectomy was time consuming for the inexperienced endoscopistwho should beware of the unique adverse events related to ERCP in patients with altered anatomy.

Background/Aims: In this study we aimed to determine the rate of concordance of endoscopic ultrasonography (EUS)-guided fine needle aspiration (FNA) diagnosis with the final diagnosis obtained by surgery or endoscopic resection and follow-up in upper gastrointestinal subepithelial lesions. Methods: We retrospectively studied patients with subepithelial lesions who underwent EUS at our center from 2007 to 2011. Results: We had a final diagnosis in 67 patients (mean age±SD, 51.23±12.48 years, 34.3% [23] female, 65.6% [44] male). EUS-FNA was performed in all of the patients. On-site pathology was not performed. In nine of the patients, the obtained material which was obtained was insufficient. The cytologic examination was benign in 31 and malignant in 27 of the patients. Based on the final diagnosis, the EUS-FNA had a sensitivity of 96%, a specificity of 100%, and a diagnostic yield of 85%. Conclusions: The diagnostic yield of EUS-FNA, in the absence of the on-site cytopathologist, is feasible for the diagnosis of subepithelial lesions of the upper gastrointestinal system.

Aim: Although preoperative chemoradiatherapy (CRT) has proven its benefits in terms of decreased toxicity, there is still a considerable amount of cases that do not receive postoperative CRT. Oncologists at different geographic locations still need to know the long-term effects of this treatment in order to manage patients successfully. The current paper reports on long-term quality of life (QOL) and late side effects after adjuvant CRT in rectal cancer patients from 5 centers in Anatolia. Methods: Rectal cancer patients treated with postoperative CRT with minimum 1-year follow-up and were in complete remission, were evaluated according to RTOG and LENT-SOMA scales. They were also asked to complete Turkish version of EORTC QLQ-C30 questionnaire and the CR-38 module. Each center participated with the required clinical data. Results: Two hundred and thirty patients with median age of 55 years participated and completed the study. Median follow-up time was 5 years. All patients received RT concomitant with chemotherapy. Common parameters that both increased functional health scales and yielded better symptom scores were long term interval after treatment and sphincter-saving surgery. In addition, surgery type and follow-up time were determined to be predictors of QOL scores and late toxicity grade. Conclusion: Postoperative CRT was found to have a great impact on the long term QOL and side effects in rectal cancer survivors. The factors that adversely affect these are abdominoperineal resection and shorter interval. The findings may encourage life-long follow-up and cooperation with patients, which should be mentioned during the initial counseling.

Purpose: Alteration in oxygen saturation is a side effect of the dye used in sentinel lymph node biopsy. The object of this study was to determine the possible effects of methylene blue on the oxygen saturation in patients undergoing sentinel lymph node biopsy. Methods: The complete peroperative records of 148 patients who underwent sentinel lymph node biopsy with intraparenchymal injection of methylene blue were reviewed. The data reviewed included the preinjection pulse oximeter saturation readings and the postinjection values until the readings returned to the preoperative levels in the postanesthesia care unit. Results: The pulse oximetry values were recorded preoperatively, after intubation and, at 15, 30, 45, and 60 minutes of the operation. The results showed that methylene blue did not cause any significant changes in oxygen saturation levels. Conclusion: We suggest that methylene blue might be preferable for the patients with concomitant disease, and for whom close monitoring of their oxygen saturation is required.
