Abdominal pain is one of the most common reasons for admission to the emergency department in the geriatric population. The aim of this study was to investigate the diseases frequently detected in elderly patients diagnosed with acute abdomen in the emergency department, the imaging methods used in the diagnostic processes of these diseases, and the prognosis of the patients. In all, 175 patients who visited the emergency department due to abdominal pain and were hospitalized with a diagnosis of acute abdomen were evaluated. The patients were categorized into seven groups according to their diagnosis as biliary diseases, pancreatitis, appendicitis, gastrointestinal system perforation, ileus, mesenteric ischemia, and atypical causes. The mean age of the patients was 76.3±7.7 years (range 65–93), and 96 (54.9%) were women. The most common causes of acute abdomen were biliary diseases and pancreatitis. Ultrasonography (88.6%) was the most frequently preferred imaging method in the emergency department, and it was most frequently used for biliary diseases. Notably, 20 (11.4%) patients were treated in the intensive care unit, and 9 (5.1%) patients died. The most common causes of acute abdomen in the geriatric population were biliary diseases and pancreatitis, and ultrasonography imaging was the most common choice for the diagnosis of these diseases. In elderly patients with abdominal pain, rapid and accurate diagnosis and selection of the correct imaging method are extremely important.

Aim: To investigate the changes in liver stiffness and immune-inflammatory markers associated with obesity and the degree of hepatic steatosis in obese children and adolescents. Methods: A total of 76 obese children and adolescents aged 6–18 years, with body mass index percentiles >95th, were included in the study. Patients with metabolic syndrome, diabetes mellitus, and chronic liver disease were excluded. A control group of 44 patients of healthy and normal-weight children was included. Laboratory values from the past month were analyzed using patient records. Shear wave elastography and ultrasound examinations were performed on a single device by the same experienced radiologist. Results: The systemic immuneinflammation index and pan-immune inflammation values were significantly higher in obese patients with hepatic steatosis compared to obese patients without hepatic steatosis (p <0.001). Liver stiffness values were significantly higher in steatotic patients compared to nonsteatotic patients (p <0.001). A significant difference was observed between hepatic steatosis grades in terms of immune-inflammation index and pan-immune inflammation value values (p <0.001). There was a strong, positive, statistically significant correlation between liver stiffness and immune-inflammation index and pan-immune inflammation value (p <0.05). Conclusions: Immune-inflammatory biomarkers and shear wave elastography may provide valuable insights into the diagnosis and follow-up of inflammation and fibrosis in the evaluation of hepatic steatosis in obese children and adolescents.

Background: The distinction between complicated and uncomplicated appendicitis is very important for the selection of the treatment method. Purpose: To investigate the sensitivity and specificity of computed tomography (CT) in differentiating between complicated and uncomplicated appendicitis to demonstrate that false negativity in differentiating these cases can be reduced when CT findings are incorporated into the clinical evaluation of patients. Material and Methods: All patients aged ≥18 years who underwent appendectomy at Malatya Training and Research Hospital in 2020 and 2021 were retrospectively screened. Of them, 283 patients were included in the study who had undergone CT before the operation. Patients with appendicitis were divided into two groups: complicated and uncomplicated, according to the results of their pathology tests. Demographic data, laboratory results, and CT images of the patients were evaluated. Results: The patients with complicated appendicitis had a significantly higher mean age ( P<0.001). The most common CT findings in patients with complicated appendicitis were moderate or severe peri-appendiceal fat stranding (PFS) and appendix wall enhancement defect (AWD). The findings with the highest sensitivity were PFS (77.9%) and AWD (69.4%). Although abscess, phlegmon, and peri-appendiceal air had the highest specificity (100%), these findings were the ones with the lowest sensitivity. According to the scoring system was developed for the differential diagnosis, CT had a sensitivity of 83.3% and a specificity of 79.2%. Conclusion: Based on the sensitivity and specificity values measured for CT according to the findings of our study, the scoring system may be useful for the differential diagnosis of complicated appendicitis.

(1) Background: In our study, we aimed to determine the accuracy rates of imaging methods for sigmoid, rectosigmoid colon, and rectum cancer. (2) Methods: Patients with tumors located in the rectosigmoid colon, sigmoid colon, and rectum who were operated on were included. Upon admission, we examined the patients’ first diagnostic colonoscopies and their preoperative repeat control colonoscopies and computed tomography (CT) report. (3) Results: In this study, 23 patients (57.5%) were male. The overall accuracy rates were 80.0% (32/40) in colonoscopy, 65.0% (26/40) in preoperative CT, and 87.5% (35/40) in retro CT, and the differences among the examination methods were statistically significant (p = 0.049). The sensitivity levels decreased to 50.0% for colonoscopy and preoperative CT and 75.0% for retro CT in rectosigmoid colon tumors. In rectal tumors, the sensitivity levels were 75.0% in colonoscopy, 60.0% in preoperative CT, and 80.0% in retro CT. In two patients, the tumor location was given incorrectly, and postoperative pathological evaluations indicated T3N0 tumors; the initially planned treatment was thus changed to include radiotherapy in addition to chemotherapy in the postoperative period because the tumor was located in the middle rectum. (4) Conclusions: Accuracy in tumor localization in sigmoid, rectosigmoid, and rectum tumors still needs to be improved, which could be accomplished with prospective studies. CT evaluations for cancer localization in this patient group should be re-evaluated by a radiologist.
