Thoracic vertebrae fracture: Is it an indicator of abdominal injury?

PURPOSE: Traumatic vertebral fracture accounts for 10-15% of trauma related admissions. While the correlation between lumbar vertebral fractures and abdominal injuries is well established, the relationship between thoracic vertebral fractures (TVF) and abdominal injuries is comparatively less well elucidated. Using a large national trauma database, we aimed to examine the incidence and severity of associated abdominal injuries in blunt trauma patients suffering from TVF. METHODS: A retrospective cohort study using the Israeli National Trauma Registry was conducted. Patients with thoracic vertebrae spine fractures following blunt mechanisms of trauma between 1997 and 2018 were examined, comparing the incidence and severity of associated intraabdominal organs injuries with and without TVF. Demographics and outcomes between the two cohorts were compared. RESULTS: From 362,924 blunt trauma patients, 4967 (1.37%) had isolated TVF. Mean age was 49.8 years and 61.9% were males. The most common mechanism of injury was fall following by MVC. The patients with TVF had significantly higher rates of increased ISS score (ISS > 16, 28.45% vs. 10.42%, p < 0.001) and higher mortality rate (3.5% vs. 2%, p < 0.0001). Patients with TVF had 2-3 times more intraabdominal organ injuries (p < 0.001). The most commonly injured organ was spleen (3.28%); followed by liver (2.64%) and kidney (1.47%). An analysis of non-isolated thoracic spine fractures showed same distribution in age, ISS, mechanisms, patterns of intra-abdominal injury, mortality rate and laparotomy rate. CONCLUSION: Clinicians should have an elevated suspicion for intra-abdominal injuries when a thoracic spine fracture is identified, which may necessitate further evaluation.

Should cholangiography be part of the management of every patient with percutaneous cholecystostomy?

INTRODUCTION: Percutaneous cholecystostomy (PCC) is a well-established treatment in patients with high surgical risk and those who failed conservative treatment. However, the role of cholangiography in the management of PCC patients is not clear. In our medical center, cholangiography is routinely performed before discharging patient with PCC. We aimed to evaluate the utility of this test and its effect on the patient's management. METHODS: The study included all patients managed with PCC between 2015 to 2017. The patients were divided to those with positive findings and those with no findings. The two groups were compered in demographical and clinical parameters. RESULTS: 119 patients underwent PCC during the study period. Indication for PCC were comorbidities in 73% and failure of conservative treatment in 27%. Cholangiography was performed in 95 patients. Third of the patients had positive findings in their cholangiography. 13 patients had CBD stones, 14 had obstruction of gallbladder and 6 had bile leak. All positive findings required changed in management. CONCLUSION: PCC is a safe procedure. Cholangiography, should be performed in every patient who was managed by PCC since it might change the management in third of the cases.

Time to surgery: Is it truly crucial in initially stable patients with penetrating injury?

BACKGROUND: Treatment recommendations for patients with penetrating abdominal injury are well established. Trauma victims with clear indications for surgery, should undergo immediate operative intervention without any delay or additional imaging. However, the optimal time for surgery remains unclear. There are some significant advantages in preoperative abdominal CT, including gathering essential information regarding a few difficult to reach anatomical areas, avoiding unnecessary explorations associated with increased morbidity and assessing the existence of extra-abdominal injuries that may have non-expectable impact on initial therapeutic plan. The aim of this study was to determine the impact of "time-to-surgery" on final medical outcomes in patients with penetrating abdominal trauma with normal blood pressure on admission. METHODS: A retrospective cohort study using the Israeli National Trauma Registry was conducted from 2000- 2018. This study included trauma patients with penetrating injuries and a systolic blood pressure of 90mmHg or above on admission. All patients included in the study were divided into three groups according to the time that lapsed from their admission to surgery: half an hour, an hour, and two hours. We assessed the outcome for each patient, including length of hospital stay, need for intensive care and mortality. Statistical analysis was performed using the Chi-square test, ANOVA test. A p-value of less than 0.05 was considered statistically significant. RESULTS: The study included 1,136 penetrating trauma patients. Among these, 78.0% (886) had sustained low-energy penetrating injury (SWPI) and 22.0% (250) had sustained high-energy penetrating injury (FAPI). Males accounted for 93.5% (1,062) of the patients. Mean age was 30.4. About 29% (327) of all the patients underwent surgery within 30 minutes from admission, 42% (475) within 30-60 min, and 29% (334) patients were operated within one to two hours. Patients who underwent surgery within 30 minutes, had worse ISS and GCS scores and were, therefore, more likely to have worse clinical outcomes. No other differences in outcomes were found in patients who were operated upon within 2 hours. CONCLUSIONS: Time to surgery within two hours from admission has no impact on final outcomes in trauma patients with penetrating injury and normal blood pressure on admission.

Should the management approach to the anterior abdominal stab wound be different in patients with self-inflicted abdominal injury?

BACKGROUND: Self-inflicted injury is a leading cause of death worldwide. It is hypothesized that due to instincts for self-preservation, the severity of abdominal injury would be decreased following suicidal self-stabbing in comparison to stab wounds from assault, and therefore a more conservative management might be considered. METHODS: All patients with isolated abdominal stab wound (SW) admitted to 19 Trauma Centers in Israel between the years 1997 and 2018 were included in the study. Patients with self-inflicted abdominal SW (Group I) were compared to victims with abdominal SW following assault (Group II). RESULTS: Group I included 9.4% (314/3324) of patients eligible for this study. Compared to Group II, Group I patients were older (median: 39 years, IQR 28,52 vs. 24 years, IQR 19,33; p<0.001), had more females (28.7% vs 4.9%, p <0.001), had longer length of hospitalization (median: 3 days vs. 2 days; p<0.001), underwent surgery more frequently (55.4% vs. 37.4%; p<0.001), and had higher mortality (2.9% vs. 0.7%; p=0.003). Possible covariates for mortality were examined and following logistic regression, self-inflicted injury remained associated with higher death rates compared to assault (OR 4.027, CI95% 1.380, 11.749; p=0.011). CONCLUSION: In this study, patients with isolated self-inflicted abdominal injuries had higher mortality and more frequently underwent abdominal surgery.
