Background and Objectives: Traumatic duodenal injury is a rare disease with limited evidence. We aimed to evaluate the risk factors for postoperative leakage and outcomes of pyloric exclusion after duodenal grade 2 and 3 injury. Materials and Methods: We reviewed a prospectively collected trauma database for the period January 2004–December 2020. Patients with grade 2 and 3 traumatic duodenal injury were included. To identify the risk factors for postoperative leakage, we used a stepwise multivariable logistic regression model and a least absolute shrinkage and selection operator (LASSO) logistic model. We constructed a receiver operator characteristic (ROC) curve to predict risk factors for postoperative leakage. Results: During the 17-year period, 179,887 trauma patients were admitted to a regional trauma center in Korea. Of these patients, 74 (0.04%) had duodenal injuries. A total of 49 consecutive patients had grade 2 and 3 traumatic duodenal injuries and underwent laparotomy. The incidence of postoperative leakage was 32.6% (16/49). Overall mortality was 18.4% (9/49). A stepwise multivariable logistic regression and LASSO logistic regression model showed that time from injury to initial operation was the sole statistically significant risk factor. The ROC curve at the optimal threshold of 15.77 h showed the following: area under ROC curve, 0.782; sensitivity, 68.8%; specificity, 87.9%; positive predictive value, 73.3%; and negative predictive value, 85.3%. There was no significant difference in outcomes between primary repair alone and pyloric exclusion. Conclusions: Time from injury to initial operation may be the sole significant risk factor for postoperative duodenal leakage. Pyloric exclusion may not be able to prevent postoperative leakage.
Objective: The ion shift index (ISI), which considers extracellular fluid ions such as phosphate, calcium, and magnesium, represents the ion shift following ischemia; concentrations of these ions are maintained within narrow normal ranges by adenosine triphosphate-dependent homeostasis. The ISI is defined as follows: {potassium (mmol/L-1) + phosphate (mmol/L-1) + Mg (mmol/L-1)}/calcium (mmol/L-1). This study investigated the possibility of predicting the 30-day survival rate of patients who underwent traumatic damage control laparotomy by comparing ISI and other laboratory findings, as well as the initial Trauma and Injury Severity Score (TRISS) and shock indices. Methods: Among the 134 patients who underwent damage control surgery between November 2012 and December 2021, 115 patients were enrolled in this study. Data regarding injury mechanism, age, sex, laboratory findings, vital signs, Glasgow Coma Scale score, Injury Severity Score, Abbreviated Injury Scale score, blood component transfusion, type of surgery, postoperative laboratory outcomes, morbidity, mortality rates, fluids administered, and volume of transfusions were collected and analyzed. Results: In univariate analysis, the odds ratio of the initial ISI was 2.875 (95% confidence interval, 1.52–5.43; P = 0.04), which showed a higher correlation with mortality compared with other indices. The receiver operating characteristic (ROC) curve and area under the ROC curve (AUC) were derived from different multivariable logistic regression models. The initial ISI had high sensitivity and specificity in predicting patient mortality (AUC, 0.7378). In addition, in the model combining the initial ISI, crystalloids, and TRISS, the AUC showed a high value (AUC, 0.8227). Conclusion: The ISI evaluated using electrolytes immediately after admission in patients undergoing traumatic damage control surgery may be a predictor of patient mortality.
Background In patients with blunt injury due to abdominal trauma, the common cause for laparotomy is damage to the small bowel and mesentery. Recently, postoperative early enteral nutrition (EEN) has been recommended for abdominal surgery. However, EEN in patients with blunt bowel and/or mesenteric injury (BBMI) has not been established. Therefore, this study aimed to identify the factors that affect early postoperative small bowel obstruction (EPSBO) and the date of tolerance to solid food and defecation (SF + D) after surgery in patients with BBMI. Methods We retrospectively reviewed patients who underwent laparotomy for BBMI at a single regional trauma center between January 2013 and July 2021. A total of 257 patients were included to analyze the factors associated with enteral nutrition tolerance in patients with EPSBO and the postoperative day of tolerance to SF + D. Results The incidence of EPSBO in patients with BBMI was affected by male sex, small bowel organ injury scale (OIS) score, mesentery OIS score, amount of crystalloid, blood transfusion, and postoperative drain removal date. The higher the mesentery OIS score, the higher was the EPSBO incidence, whereas the small bowel OIS did not increase the incidence of EPSBO. The amount of crystalloid infused within 24 h; the amount of packed red blood cells, fresh frozen plasma, and platelet concentrate transfused; the time of drain removal; Injury Severity Score; and extremity abbreviated injury scale (AIS) score were correlated with the day of tolerance to SF + D. Multivariate analysis between the EPSBO and non-EPSBO groups identified mesentery and small bowel OIS scores as the factors related to EPSBO. Conclusion Mesenteric injury has a greater impact on EPSBO than small bowel injury. Further research is needed to determine whether the mesentery OIS score should be considered during EEN in patients with BBMI. The amount of crystalloid infused and transfused blood components within 24 h, time of drain removal, injury severity score, and extremity AIS score are related to the postoperative day on which patients can tolerate SF + D.
An isolated injury of the gallbladder after low-energy blunt abdominal trauma is rare. Here we report the case of a patient with biliary peritonitis caused by an impacted gallstone in the cystic plate after a simple slip-and-fall injury on the road.
The therapeutic approach for colon injury has changed continuously with the evolution of management strategies for trauma patients. In general, immediate laparotomy can be considered in hemodynamically unstable patients with positive findings on extended focused assessment with sonography for trauma. However, in the case of hemodynamically stable patients, an additional evaluation like computed tomography (CT) is required. Surgical treatment is often required if prominent mesenteric extravasation, free fluid, bowel infarction, and/or colon wall perforation are observed. However, immediate intervention in hemodynamically stable patients without indications for surgical treatment remains questionable. Three patients with colon and mesocolon injuries caused by blunt trauma were treated by nonoperative management. At the time of admission, they were alert and their vital signs were stable. Colon and mesocolon injuries, large hematoma, colon wall edema, and/ or ischemia were revealed on CT. However, no prominent mesenteric extravasation, free fluid, bowel infarction, and/or colon wall perforation were observed. In two cases, conservative treatment was performed without worsening abdominal pain or laboratory tests. Follow-up CT showed improvement without additional treatment. In the third case, follow-up CT and percutaneous drainage were performed in considering the persistent left abdominal discomfort, fever, and elevated inflammatory markers of the patient. After that, outpatient CT showed improvement of the hematoma. In conclusion, nonoperative management can be considered as a therapeutic option for mesocolon and colon injuries caused by blunt trauma of selected cases, despite the presence of large hematoma and ischemia, if there are no clear indications for immediate intervention.
