    The Relationship Between Hyperplastic Gastric Polyps And Helicobacter Pylori
    (Duzce Univ, 2021) Erdal, Harun; Sakin, Yusuf Serdar; Cetin, Mehmet Fuat; Celik, Bulent; Onmez, Attila; Uygun, Ahmet; Gulsen, Mustafa
    Objective: Helicobacter pylori (H. pylori) is a gram-negative bacterium. It is urease positive, mobile, microaerophilic, and spiral-shaped, and it settles in the stomach and the proximal duodenum. It is associated with chronic gastritis, stomach ulcers, duodenal ulcers, stomach cancer, and MALT lymphoma. It can also cause premalignant lesions, such as metaplasia and gastric atrophy. Although several studies are investigating the correlation between H. pylori and hyperplastic polyps (HPs) of the stomach, uncertainty in this regard continues. Methods: Data from 5378 patients who underwent esophagogastroduodenoscopy at the Department of Gastroenterology, Gulhane Training and Research Hospital, University Of Health Sciences between October 2016 and March 2019 were retrospectively analyzed, and patients with gastric polyps were evaluated for polyp pathologies and normal mucosa biopsies. Results: Sixty-one stomach polyps were detected in 49 patients after the retrospective analysis of the data between October 2016 and March 2019. Of the polyps found, 36 were hyperplastic (73%). There was no statistically significant difference between HPs and the presence of H. pylori, age, gender, anatomical location of polyps in the stomach, size, number, presence of metaplasia, or atrophy. The mean age was statistically lower in H. pylori-positive cases. Conclusions: No correlation was observed between HPs and the presence of H. pylori. There is a need for more extensive, multi-centered, and prospective studies evaluating the relationship between HPs and H. pylori.

    Residual Gastric Volume Relationship and Weight Loss After Laparoscopic Sleeve Gastrectomy
    (Springer, 2020) Dogan, Sami; Onmez, Attila; Cetin, Mehmet Fuat; Ozaydin, Ismet; Pehlivan, Mevlut
    Background Laparoscopic sleeve gastrectomy (LSG) has become a popular procedure for treating obesity. Excessive residual gastric volume (RGV) may be one cause of insufficient weight loss following this surgery. The purpose of this study was to investigate the relationship between weight loss and the RGV measured during surgery over a 2-year follow-up period. Methods All patients undergoing LSG at our university surgery department were included in this prospective observational study. During the operation, the pylorus was grasped with a laparoscopic clamp, and saline solution dyed with methylene blue was introduced using an intraluminal glass-tipped injector when the residual stomach became fully visible. The amount of fluid given when the remaining gastric tissue ceased expanding was noted. The patients were divided into three groups depending on the volume of the residual gastric tissue. Percentages of excess weight loss (EWL%) were also evaluated 6, 12, and 24 months after the LSG. Results Sixty-two patients (50 females and 12 males) with a mean age of 36 (17-56) years were included in the study. There was no significant difference between the preoperative and postoperative body mass index values (p = 0.407 and p = 0.337, respectively) or between the preoperative and postoperative weight (p = 0.081 and p = 0.517, respectively) among the groups. A comparison of the participants' weight losses and EWL% values after 6, 12, and 24 months of follow-up revealed no significant difference among the groups at any time point (p > 0.005). Conclusion Greater weight loss was observed as the RGV decreased over the 24-month follow-up period. However, that weight loss was not statistically significant.

    Unpredictable Event during EUS-Guided Hepaticojejunostomy
    (Duzce Univ, Fac Medicine, 2023) Sirin, Abdullatif; Cetin, Mehmet Fuat; Tokmak, Salih
    Endoscopic ultrasound (EUS)-guided biliary drainage is a therapeutic alternative method in patients with cholestasis where the ampulla of Vater cannot be reached because several reasons. An unfortunate complication during EUS-guided biliary drainage was presented in this report. A 53 -year -old male patient presented with jaundice and pruritus. He had a history of total gastrectomy due to gastric cancer. An abdominal tomography scan detected a tumoral mass in the common bile duct due to the recurrence of gastric cancer. We decided to perform EUS-guided hepaticojejunostomy because biliary drainage cannot be obtained by conventional methods and percutaneous drainage impairs patient comfort. A double pigtail plastic stent was placed from the jejunum into the segment -3 bile duct towards the hilus. After that echoduodenoscope was removed to the outside gently. We noticed that the stent was stuck in the echoduedonoscope elevator. We reached into the bile duct again and placed a doublepigtail plastic stent successfully.
