Background Roughly 5% of patients with blunt abdominal trauma (BAT) have a blunt bowel and/or mesenteric injury (BBMI). Determining the need for operative management in these patients can be challenging when hemodynamically stable. Single center studies have proposed scoring systems based on CT findings to guide management. Our study aimed to determine the predictability of abdominopelvic CT scan (CT A/P) findings in conjunction with clinical exam to determine the necessity of operative intervention for BBMI. Methods Patients presenting from 2017 to 2022 to the University of South Alabama Level 1 Trauma Center after motor vehicle collision were retrospectively reviewed. Patients with CT findings suggestive of BBMI were further analyzed, noting CT findings, Glasgow coma scale (GCS), shock index, abdominal exam, operative or nonoperative management, and intraoperative intervention. Results 1098 patients with BAT underwent CT A/P. 139 patients had ≥1 finding suggestive of BBMI. 38 patients underwent surgical exploration and 30 had surgically confirmed BBMI. 27 patients required intervention for BBMI. Univariate analysis indicated that pneumoperitoneum ( p < 0.0001), active extravasation of contrast ( p = 0.0001), hemoperitoneum without solid organ injury (SOI) ( p < 0.0001), peritonitis ( p < 0.0001), and mesenteric stranding( p < 0.05) were significantly associated with intervention. Conclusion In total, 30 patients had surgically confirmed BBMI. Active extravasation, pneumoperitoneum, hemoperitoneum without SOI, mesenteric stranding, and peritonitis were significant indicators of BBMI requiring intervention. CT and clinical findings cannot reliably predict the need for surgical intervention without ≥1 of these findings. Initial nonoperative management with serial clinical exams should be strongly considered to reduce incidence of nontherapeutic laparotomies.
