Optimal Management of Traumatic Abdominal Wall Hernias Remains Unclear.

High-energy, blunt force trauma to the abdomen results in an abdominal wall injury (AWI) in up to 9% of patients. In 1% of blunt abdominal trauma, they result in a traumatic abdominal wall hernia (TAWH). Optimal management of these injuries remains unclear. Because they are the result of a high-energy mechanism, concomitant serious abdominal organ injuries are common. This has prompted some to advocate that the presence of a TAWH on physical exam mandates exploratory laparotomy. However, delayed repairs have better outcomes and nontherapeutic celiotomy should be avoided. Similarly debated is the expanding use of minimally invasive techniques and the use of mesh for hernia repairs. Overall, the presence of a TAWH is likely not an absolute indication for emergency surgery. Rather, it is an indicator of high-energy impact and associated with a high rate of visceral injury. These patients require a close observation for clinical decline and development of typical indicators for laparotomy.

Multi-System Inflammatory Syndrome Presenting as Non-Specific Colitis: A Medical Diagnosis with a Surgical Presentation.

A 20-year-old woman with previous COVID-19 diagnosis presented with abdominal pain and colitis on CT scan. She was admitted in septic shock, with etiology of colitis unclear. After resuscitation, antibiotics, and steroids, she clinically deteriorated. Worsening Clostridioides difficile infection was most likely and she was taken to the operating room. Intraoperatively, only a segment of transverse colon appeared abnormal on gross and endoscopic evaluation. Total colectomy was deferred in favor of segmental resection. Given her unusual disease pattern and recent COVID-19 infection, diagnosis of MIS-C was considered. Steroids were continued and treatment broadened to include heparin and IVIG. The patient returned to the operating room for planned reexploration, endoscopy, and end colostomy. On hospital day three, the patient had an acute mental status change. Computed tomography demonstrated acute cerebral edema with brainstem herniation. The family chose comfort-care measures. Final pathology from the transverse colon demonstrated COVID-19-associated vasculitis.

Contemporary management and outcomes of penetrating colon injuries: Validation of the 2020 AAST Colon Organ Injury Scale.

INTRODUCTION: The American Association for the Surgery of Trauma Colon Organ Injury Scale (OIS) was updated in 2020 to include a separate OIS for penetrating colon injuries and included imaging criteria. In this multicenter study, we describe the contemporary management and outcomes of penetrating colon injuries and hypothesize that the 2020 OIS system correlates with operative management, complications, and outcomes. METHODS: This was a retrospective study of patients presenting to 12 Level 1 trauma centers between 2016 and 2020 with penetrating colon injuries and Abbreviated Injury Scale score of <3 in other body regions. We assessed the association of the new OIS with surgical management and clinical outcomes and the association of OIS imaging criteria with operative criteria. Bivariate analysis was done with χ 2 , analysis of variance, and Kruskal-Wallis, where appropriate. Multivariable models were constructed in a stepwise selection fashion. RESULTS: We identified 573 patients with penetrating colon injuries. Patients were young and predominantly male; 79% suffered a gunshot injury, 11% had a grade V destructive injury, 19% required ≥6 U of transfusion, 24% had an Injury Severity Score of >15, and 42% had moderate-to-large contamination. Higher OIS was independently associated with a lower likelihood of primary repair, higher likelihood of resection with anastomosis and/or diversion, need for damage-control laparotomy, and higher incidence of abscess, wound infection, extra-abdominal infections, acute kidney injury, and lung injury. Damage control was independently associated with diversion and intra-abdominal and extra-abdominal infections. Preoperative imaging in 152 (27%) cases had a low correlation with operative findings ( κ coefficient, 0.13). CONCLUSION: This is the largest study to date of penetrating colon injuries and the first multicenter validation of the new OIS specific to these injuries. While imaging criteria alone lacked strong predictive value, operative American Association for the Surgery of Trauma OIS colon grade strongly predicted type of interventions and outcomes, supporting use of this grading scale for research and clinical practice. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.
