Paraduodenal hernias are rare congenital malformations consisting of incomplete rotation of the midgut, which may lead to intestinal obstruction or simply be detected as an incidental finding at autopsy or laparotomy. We report a case of left paraduodenal hernia diagnosed preoperatively by computed tomography and operated on in an emergency setting for signs of peritoneal irritation. A misdiagnosis had been made when the patient suffered his first attack 6 months earlier and he had been treated for familial Mediterranean fever. We reduced the small bowel loops from the left paraduodenal hernia sac with ligation and transection of the inferior mesenteric vessels. The patient was discharged from hospital on postoperative day 4 after an uneventful recovery.

The distinction between tuberculous peritonitis and peritoneal carcinomatosis is extremely difficult in patients with omental cake appearance on computed tomography and elevated CA-125 level. A 21-year-old female presented with abdominal distention, diarrhea, nausea, fever, weight loss, and night sweats. Serum CA-125 level was 563 U/L (normal range: <35 U/L) and other tumor markers were within normal range. Radiologic studies showed massive ascites, smooth minimal thickening and increased contrast enhancement of peritoneum, omental nodularities, hepatomegaly, and right pleural effusion. No underlying malignancy that could cause this condition was detected clinically and radiologically. Ultrasound-guided omental tru-cut biopsy was performed to exclude carcinomatosis peritonei. Histopathologic examination showed small-medium-sized granulomas with caseous necrosis. Molecular microbiology tests of biopsy specimens confirmed diagnosis of tuberculosis. In conclusion, tuberculous peritonitis should be in differential diagnosis of a patient with ascites, omental nodularities and elevated serum CA-125 levels.

Acute appendicitis is the most common cause of acute abdomen requiring surgery. Although the standard treatment has been surgery, it has been seen in recent years that treatment is possible with antibiotics and non-operative observation. In this study, our aim is to determine whether the computed tomography (CT) findings in patients diagnosed with acute appendicitis can be used for directing treatment. A retrospective analysis was conducted on 138 patients with acute appendicitis who underwent CT between 2015 and 2019. In this study, medical treatment group (n = 60) versus surgical treatment group (n = 78) and successful antibiotic treatment group (n = 23) versus unsuccessful antibiotic treatment group (n = 14) were compared. Appendiceal wall thickness, appendiceal diameter, the severity of mural enhancement, intra-abdominal free fluid, the severity of periappendiceal fat stranding, size of pericecal lymph node, appendicolith, adjacent organ findings, and the CT appendicitis score of groups were compared with Pearson Chi-square and Mann–Whitney U tests. Multivariable logistic regression was used to identify predictors of surgical treatment, expressed as odds ratios (ORs) with 95% CIs. Diagnostic efficacies of appendiceal diameter, the CT appendicitis score, and the developed model were quantified by receiver operating characteristic curves. Appendiceal diameter (P < .001), adjacent organ findings (P = 0.041), the CT appendicitis score (P < .001), the severity of periappendiceal fat stranding (P = .002), appendicolith (P = .001), and intra-abdominal free fluid (P < .001) showed statistically significant differences between the medical and surgical treatment groups. According to the logistic regression test, if the patients are with appendiceal diameter ≥13 mm (OR = 5.1, 95% CI: 1.58-16.50), appendicolith (OR = 4, 95% CI: 1.17-13.63), and intra-abdominal free fluid (OR = 3.04, 95% CI: 1.28-7.20), surgeons should prefer surgical treatment. The area under the curves for the CT appendicitis score, the appendiceal diameter, and the model were 0.742 (95% CI: 0659-0824), 0.699 (95% CI: 0.613-0.786), and 0.745 (95% CI: 0.671-0.819), respectively. As the successful and unsuccessful medical treatment groups were compared, the only significant parameter was the severity of mural enhancement (P = .005). CT findings may be helpful in patients with uncomplicated acute appendicitis whose treatment surgeons are indecisive about. We can recommend surgical treatment in cases with appendix diameter ≥13 mm, intra-abdominal free fluid, appendicolith, high CT appendicitis score, and severe mural enhancement.

Background: Thoracic kyphosis has been increasingly associated with altered intra-abdominal and diaphragmatic dynamics, potentially contributing to gastroesophageal reflux disease (GERD) and hiatal hernia (HH). While previous studies have shown a relationship between spinal deformities and GERD symptoms, these findings have been largely observational, with few morphometric analyses. No prior study has directly quantified the relationship between thoracic curvature and hiatal surface area (HSA) using standardized computed tomography (CT)-based methods. Furthermore, existing studies have typically focused on patients with visible hernias, limiting understanding of early, subclinical anatomical changes. This study addresses this gap by evaluating whether thoracic kyphosis is associated with measurable hiatal enlargement, even in the absence of overt HH. Methods: In this retrospective, single-center study, 100 adult patients (50 with thoracic kyphosis, defined as a Cobb angle of ≥50° and 50 age- and sex-matched controls) underwent multidetector CT (MDCT). Hiatal surface area (HSA) was measured on a standardized oblique axial plane aligned with the diaphragmatic crura. Correlation and multivariable regression analyses were performed to assess relationships between Cobb angle and HSA. Results: The kyphosis group showed significantly larger HSA than controls (5.14 ± 1.31 cm² vs. 3.59 ± 0.74 cm²; p < 0.001). A moderate positive correlation was found between Cobb angle and HSA (r = 0.336, p = 0.017). Multivariable analysis identified the Cobb angle as an independent predictor of HSA (β = 0.028; p = 0.017), while age and sex were not significant predictors. No overt herniation was present in any subject. Conclusions: This is the first CT-based morphometric study to demonstrate that thoracic kyphosis is associated with hiatal enlargement, even in the absence of overt herniation. These findings support the hypothesis that postural spinal deformities may predispose individuals to GERD by structurally remodeling the diaphragmatic hiatus.
