Comparison between 64 Slice CT Scanner and a 256 Slice CT scanner in the Diagnosis of Diaphragmatic Hernia Following Blunt Trauma: a Retrospective Study

Abstract

Aim: To compare between 64 slice CT scanner and a 256 slice CT scanner in the diagnosis of Diaphragmatic Hernia following Blunt Trauma

Study design: A retrospective comparative study

Place and Duration: This study was conducted at, Bolan Medical Complex Hospital Quetta Pakistan. from March 2020 to March 2021.

Methodology: All the enrolled patients were divided into two groups and preoperatively evaluated with 256 CT scanners and 64 slices CT scanners. Electronic medical records were used for taking information related to demographics, characteristics of injury, and outcomes. The presence or absence of traumatic diaphragm injuries was confirmed after reviewing the operative reports.

Results: Regarding preoperative CT scan, we observed that 61.6% of cases were already detected with CT scan before operative visualization. No significant difference was observed in terms of injury length between the two groups.  We observed that only 77 (47.1%) of cases were accurately diagnosed with diaphragmatic injury before operative visualization.

Conclusion: Our results concluded that intraoperative diagnosis of traumatic diaphragm injuries is the golden standard for suspected cases of TDI because almost 40% of injuries were not diagnosed preoperatively even with the high-resolution CT.
