Microsievert Wide-Volume Versus Spiral Computed Tomography Using an Automatic Exposure Control System in the Diagnosis of Foreign Body Aspiration in Children.

BACKGROUND: Foreign body aspiration (FBA) in childhood is a life-threatening condition that necessitates prompt management to prevent devastating complications. Different imaging methods are used in the diagnosis of FBA. OBJECTIVE: The aim of this study was to compare the diagnostic value and dose of microsievert wide-volume computed tomography (µSv-WV-CT) with multidetector computed tomography using an automatic exposure control system (MDCT-AEC) in children with FBA. MATERIAL AND METHODS: In this single-center cross-sectional study, 102 cases diagnosed with FBA between September 2013 and September 2021 were retrospectively evaluated. The patients were divided into 2 groups according to the diagnostic modality used: group A, µSv-WV-CT (2016-2021) and group B, MDCT-AEC (2013-2021). The diagnostic performance and radiation dose of the 2 groups were statistically compared. RESULTS: The diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) of the 2 groups was similar. The mean effective radiation dose of group A was 34.89 ± 0.01 µSv, which was significantly lower than that of group B (179.75 ± 114.88 µSv) ( P < 0.001). CONCLUSION: In children with suspected FBA, µSv-WV-CT at a lower radiation dose had similar diagnostic performance to MDCT-AEC.

Minimally invasive Ivor-Lewis esophagectomy for esophageal cancer.

Background: In this study, we present our minimally invasive Ivor-Lewis esophagectomy technique and survival rates of this technique. Methods: Between September 2013 and December 2020, a total of 140 patients (56 males, 84 females; mean age: 55.5±10.3 years; range, 32 to 76 years) who underwent minimally invasive Ivor- Lewis esophagectomy for esophageal cancer were retrospectively analyzed. Preoperative patient data, oncological and surgical outcomes, pathological results, and complications were recorded. Results: Primary diagnosis was esophageal cancer in all cases. Minimally invasive Ivor-Lewis esophagectomy was carried out in all of the cases included in the study. Neoadjuvant chemoradiotherapy was administrated in 97 (69.3%) of the cases. The mean duration of surgery was 261.7±30.6 (range, 195 to 330) min. The mean amount of intraoperative blood loss was 115.1±190.7 (range, 10 to 800) mL. In 60 (42.9%) of the cases, complications occurred in intraoperative and early-late postoperative periods. The anastomotic leak rate was 7.1% and the pulmonary complication rate was 22.1% in postoperative complications. The mean hospital stay length was 10.6±8.4 (range, 5-59) days and hospital mortality rate was 2.1%. The median follow-up duration was 37 (range, 2-74) months and the three- and five-year overall survival rates were 61.8% and 54.6%, respectively. Conclusion: Minimally invasive Ivor-Lewis esophagectomy can be used safely with low mortality and long-time survival rates in esophageal cancer.
