    Abstract A 48-year-old female with complaints of gastrointestinal symptoms such as abdominal pain, fatigue, vomiting, nausea, and weight loss was diagnosed with neuroendocrine tumor after removal of a 2 mm lesion from the stomach with endoscopic biopsy. Her magnetic resonance imaging that was performed due to on-going symptoms showed multiple linear hypointense lesions in the liver. Positron emission tomography/computed tomography (PET/CT) scan was performed for differential diagnosis, which showed high fluorodeoxyglucose (FDG) uptake in these lesions. Clinical and laboratory findings revealed the final diagnosis as Fasciola hepatica. The imaging features of this case is presented to aid in differentiating this infectious disease from malignancy and avoid misdiagnosis on FDG-PET/CT.

    Abstract INTRODUCTION[|]The incidence of gastric polyps (GPs) greatly differs according to study populations and was found to be 0.33%–6.7% in various studies. The majority of GPs are composed of hyperplastic polyps (HPs), fundic gland polyps (FGPs), and adenomatous polyps (APs). Although APs have a high risk of malignant potential, sporadic FGPs have no malignant potential. Conversely, HPs have a low risk of malignant potential. It is not sufficient to perform a biopsy to identify the polyp type and the presence of dysplasia; thus, some polyps may require multiple biopsies or total excision.[¤]METHODS[|]This retrospective study included patients with GPs or polypoid lesions found on esophagogastroscopy with polyp or malignant histology on biopsy at Ankara Numune Training and Research Hospital Endoscopy Unit between 2005 and 2011.[¤]RESULTS[|]In a series of 56.300 upper endoscopies, 192 patients (0.34%) were found to have GPs. Among the patients, 51 (26.6%) were men and 151 (73.4%) were women. The average age of the patients was 61.9+-13.3 (14–90) years. The frequency of HPs, APs, and FGPs were 88%, 2.6%, and 1.6%, respectively. The size of the polyps was ≤1 cm in 137 (70%) patients. One polyp was determined in 141 (73.4%) patients. The most common localizations of polyps were the antrum and corpus. Endoscopic snare polypectomy was performed in 64 patients. One bleeding episode was observed, which required endoscopic treatment after ESP.[¤]DISCUSSION AND CONCLUSION[|]In our study, the GP frequency was low (0.34%), whereas the frequency of HP maybe high due to the high frequency of Helicobacter pylori (HPy) infection in our country. The frequency of FGP is probably low due to the high frequency of HPy infection and the short-term use of proton-pump inhibitors.[¤]

    Abstract Due to differences in prognosis and management, it is important to subclassify esophageal carcinoma. Esophageal lymphoepithelioma-like carcinoma (LELC) is extremely rare, with only a few cases reported to date. Review of the literature revealed case reports describing lesions with similar histology. We present a 69-year-old man with a giant pedunculated-polypoid lesion of the esophagus shrinking the lumen. Endoscopic excision of the tumor was performed and final histopathological diagnosis was confirmed to be LELC. In contrast to a previous case with a more aggressive course and a recurrent lesion, our patient died of his disease within 8 months of diagnosis. Here we discuss the endoscopic and radiologic findings of the case and a review of the literature.

    Abstract Objective: In the present study, we aim to investigate general and endoscopic findings of the patients who were hospitalized in our clinic because of upper gastrointestinal system bleeding (UGSB). Methods: The files of 403 patients who applied to our clinic between January 2014 and December 2014 with UGSB diagnosis were scanned retrospectively. The de­mographic, laboratorial and endoscopic findings of the patients were examined. Results: The average age of 403 patients were 61.12±17.1 (min. 17- max. 96) and while 263 of these patients were male (65.3(%), 140 of them were female (34.7%). Of all, 234 patients had an additional disease. The most fre­quently observed diseases were hypertension, diabetes mellitus and coronary artery. 259 (64.3%) of the patients used to take at least one drug and 212 (52.6%) of the patients used to get non-steroid anti-inflammatory drugs and/or aspirin. The most common reasons of UGSB were duodenal ulcer in 158 patients (39.2%), stomach ulcer in 97 patients (24%), erosive gastroduodenitis in 66 patients (16.3%) and esophageal varices in 38 patients (9.4%). Unfortunately, 18 of the patients died. Conclusion: The most common reason of UGSB is duo­denal ulcer bleeding. In spite of the technological devel­opment nowadays, it is a disease which has mortality.

    Abstract Introduction. The use of prognostic models for cirrhotic patients admitted to the medical intensive care unit (ICU) is of great importance, since they provide an objective evaluation for a group of patients with high mortality rates and high resource utilization.Objective. To evaluate the validity and to compare the prognostic predictive value of the CTP, MELD, SOFA and APACHE II scoring systems in cirrhotic patients admitted to the ICU, the CTP and MELD models being exclusive for patients with liver disease.Material and methods. Commonly used predictors of mortality such as age, sex, CTP, MELD, APACHE II and SOFA were evaluated, and their prognostic value was investigated.Results. A total of 201 patients were included in this study. Patients who survived had mean CTP score of 9.5 ± 2.4, MELD score 18.1 ± 7.1, APACHE II score of 13.4 ± 4.8 and SOFA score of 4.2 ± 2.6, compared to respective scores of 11.4 ± 2.8, 28.0 ± 11.2, 24.6 ± 10.4 and 8.7 ± 4.0 in patients who died. The difference between groups was statistically significant for each of one of the scoring systems (p < 0.001).Conclusion. In this study, SOFA was found to be the most powerful predictor of prognosis for cirrhotic patients admitted to the ICU. This was followed by APACHE II, MELD and CTP models, in descending order of strength (AUROC values of 0.847, 0.821, 0.790 and 0.724, respectively).

    Abstract Objective: Foreign body ingestion is an important public health problem. We pointed to this subject and aimed to determine the effectiveness of flexible endoscopic procedure in this study. Methods: We evaluated retrospectively fifty children having foreign body in their upper gastrointestinal system, who underwent flexible endoscopic procedure. Results: Of the patients, mean age was 5.5 ± 4 years old (range: 0.5-16 years), 64% was female. Ingested foreign bodies were coin (58%), pin (10%), battery (6%), nail (6%), necklace (6%), safety pin (4%) and sewing pin, wire hairclip, ring, button and chicken skin. In endoscopic procedure, foreign bodies were seen in upper esophagus (32%), middle esophagus (26%), lower esophagus (8%), stomach (18%), bulbus (4%) and second part of duodenum (8%), but were not seen in 4% of the cases. While 94% of foreign bodies were endoscopically removed, 6% of them were pushed to stomach with gastroscope from esophagus and left for spontaneous passage. Any important complication was developed. Conclusion: Flexible endoscopic procedure is an effective and safe method for removal of gastrointestinal system foreign bodies in children.
