One of the most common post-operative deficiencies after bariatric surgery is iron deficiency and one of the important determinants of postoperative iron deficiency is the preoperative condition. In this study, it was aimed to investigate the relationship between iron levels and histopathological findings observed in gastric tissue resected in sleeve gastrectomy. Preoperative and postoperative iron levels were compared with the presence of inflammation, atrophy, Helicobacter pylori, intestinal metaplasia, lymphoid follicles, and lymphoid aggregates observed in patients operated due to morbid obesity. The postoperative serum iron levels and preoperative values were compared and a statistically significant increase was found due to the use of iron-containing preparations after the operation. Among the parameters evaluated, inflammation, atrophy, Helicobacter pylori, intestinal metaplasia, and the presence of lymphoid follicles were not found to be associated with iron levels, but it was noted that the presence of lymphoid aggregate in all cases and male cases was correlated with preoperative low iron levels (p values 0.047 and 0.015 respectively). In this study, which investigated the role of histopathological findings in the prediction of iron deficiency in sleeve gastrectomies, the relationship between preoperative iron levels, which was reported to be predictive for post-operative iron deficiency, and the presence of lymphoid aggregates was revealed. It is thought that other histopathological findings such as the presence of lymphoid follicle and Helicobacter pylori are also important in terms of iron levels but could not be revealed due to the limitations of the study. © 2021 Ondokuz Mayis Universitesi.

INTRODUCTION: One of the most important factors influencing post-transplant success in kidney transplantation is preserving the viability of the organ from removal to transfer into the recipient. AIM: This study aimed to reduce the energy requirement with thiopental doses administered before organ transplantation, and to increase the organ viability by minimizing the tissue damage during the cold ischemia process. MATERIALS AND METHODS: Twenty female Wistar albino rats were divided into two groups: control group (group C), and thiopental group (group T). In group C, a midline incision was performed, and the renal artery was isolated under ketamine and xylazine anesthesia. A standard organ storage solution (cooled to +4°C) was used for kidney perfusion. Nephrectomy was applied, and the removed kidneys were placed into +4°C standard organ storage solution and stored at +4°C for 12 hours. Animals in group T were subjected to the procedures explained above under 85 mg/kg thiopental sodium anesthesia. After 12-hour storage, samples from the kidney tissues were fixed in 10% neutral buffered formalin. Histopathological evaluation and apoptosis detection via TUNEL method were performed. RESULTS: Tubular necrosis was more extensive in group C compared with that in group T and this difference was statistically significant. Similarly, vacuolization was widely observed in group C, and this increase was also statistically significant. For the 'dilatation of Bowman's space' parameter, a significant decrease was observed in group T compared with group C. When the apoptotic index values of both groups were examined, it was seen that they were lower in group T than those in group C. This result was statistically significant. CONCLUSIONS: These data suggest that thiopental provides protection to the kidney tissue during the cold storage process. Thiopental has been shown to decrease the number of apoptotic cells in the kidney tissue when administered to the donor before organ transplantation, increasing the organ viability.
