RESUMO
BACKGROUND: The purpose of this study is to report the prevalence of acute kidney injury (AKI) after trauma in our center, describe the risk factors associated with AKI, and determine whether these risk factors help avoid AKI. MATERIALS AND METHODS: We retrospectively analyzed the data which were prospectively collected from a single center trauma registry from January 2017 to December 2018. Patients who were <16 years of age, patients with burns, and patients with chronic kidney disease were excluded from the present study. AKI was defined according to the risk, injury, failure, loss of the kidney function, and end-stage kidney disease (RIFLE) classification from serum creatinine alone. A logistic regression analysis was performed to identify prehospital and early hospital risk factors for AKI. RESULTS: There were 806 trauma patients recorded in the database. One hundred thirty cases were excluded based on the abovementioned exclusion criteria. Six hundred seventy-six patients were included in the analysis. The prevalence of AKI in the overall population was 14.5% including 10.5% of patients with stage R, 3.0% of patients with stage I and 1.0% with stage F. The incidence of AKI increased to 36.3%, 12.1% and 3.3% in the subgroup of patients with hemorrhagic shock. The multivariate analysis revealed that the minimum prehospital systolic blood pressure and arterial lactate level were independent predictors of AKI. The model showed good discrimination with an area under the receiver operating characteristic curve (AUC-ROC) of 0.867 and 0.852 in the prediction of AKI stage I or F. The cutoff values were ≤126 mmHg and ≥2.5 mmol/L, respectively. CONCLUSION: These parameters showed good performance in the early prediction of AKI after trauma. They are associated with the early onset of AKI after trauma and may be an early predictor of the effects of treatment to prevent AKI.

PURPOSE: Open abdominal management (OAM) is being adopted increasingly frequently in nontrauma patients. This study assessed the effectiveness of OAM in nontrauma older adults. METHODS: We retrospectively reviewed all adults who underwent nontrauma emergency laparotomy requiring postoperative intensive care unit (ICU) management between September 2012 and August 2017 at our hospital. Patients ≥ 80 years old, who underwent OAM, were compared with those < 80 years old. The primary outcome was the 90-day mortality. Secondary outcomes were the 30-day mortality, unplanned relaparotomy, and the ICU length of stay (LOS). RESULTS: The OAM group comprised 58 patients, including 27 who were ≥ 80 years old. The patients ≥ 80 years old in the OAM group had a significantly higher 90-day mortality rate (33% vs. 10%; p = 0.027) than those < 80 years old. There were no significant differences in the 30-day mortality rate, patients' unplanned relaparotomy rate, or ICU LOS between the patients ≥ 80 years old and those < 80 in the OAM group. CONCLUSIONS: Older adults who underwent OAM had a significantly higher mortality rate than younger patients. However, the OAM strategy for older nontrauma patients may still be useful and reasonable considering the severe condition of these patients.

Background: The utility of resuscitative endovascular balloon occlusion of the aorta (REBOA) in children remains unclear. Case Presentation: An 11-year-old patient with liver trauma with massive extravasation was transported to a local hospital, where an emergency trauma surgery was unavailable. Following the placement of REBOA as a bridge to hemostasis, she was transferred to our hospital by a firefighting helicopter with balloon occlusion. Immediately, she underwent damage control laparotomy and transcatheter arterial embolization. She was subsequently discharged from the hospital 6 months after the accident without complications. Conclusion: REBOA as a bridge to hemostasis may be useful for pediatric patients.
RESUMO
Colorectal perforation with systemic peritonitis requires prompt surgical attention, and damage control surgery (DCS) is performed in patients with severe injuries. This study aimed to retrospectively investigate the efficacy of DCS in patients with colonic perforation. Materials and Methods: From January 2013 to December 2019, 131 patients with colorectal perforation underwent emergency surgery at our hospital. Among these, 95 patients required postoperative intensive care unit management and were included in this study; of these patients, 29 (31%) underwent DCS, and 66 (69%) underwent primary abdominal closure (PC). Results: Patients who underwent DCS had significantly higher Acute Physiology and Chronic Health Evaluation II (23.9 [19.5-29.5] vs. 17.6 [13.7-22]; P<0.0001) and Sequential Organ Failure Assessment (SOFA) (9 [7-11] vs. 6 [3-8]; P<0.0001) scores than did those who underwent PC. The initial operation time was significantly shorter for DCS than for PC (99 [68-112] vs. 146 [118-171]; P<0.0001). The 30-day mortality and colostomy rates were not significantly different between the two groups. Conclusions: The results suggest that DCS is useful in the management of acute generalized peritonitis caused by colorectal perforation.
RESUMO
PURPOSE: The rate of surgical site infection (SSI) after surgery for secondary peritonitis is very high. This study investigated the relationship between intraoperative procedures of emergency surgery for nonappendiceal perforation peritonitis and deep incisional or organ-space SSI. METHODS: This prospective, two-center observational study included patients aged ≥ 20 years who underwent emergency surgery for perforation peritonitis between April 2017 and March 2020. We compared patients with deep incisional or organ-space SSI (Group S) to patients without SSIs or with superficial incisional SSIs (Group C). Thereafter, we evaluated the association between intraoperative technical variables and deep incisional or organ-space SSI using a multivariate logistic regression model. All multivariate analyses were adjusted for potentially relevant risk factors (e.g., age, body mass index, diabetes, smoking habit, and National Nosocomial Infection Surveillance risk index). RESULTS: Of the 75 participants, 14 were in Group S and 61 were in Group C. The use of a wound protector device was significantly associated with decreased odds of deep incisional or organ-space SSI (adjusted odds ratios [AOR], 0.017; 95% confidence intervals [CI] 0.0014-0.19, p = 0.0011). A 1000 ml increase in intra-abdominal lavage with normal saline was significantly associated with increased odds of deep incisional or organ-space SSI (AOR: 1.28, 95% CI 1.02-1.61, p = 0.033). CONCLUSION: Wound protector devices should be used in emergency surgery for nonappendiceal perforation peritonitis. Excessive intra-abdominal lavage with normal saline for peritonitis may have unsatisfactory benefits and increases the incidence of deep incisional or organ-space SSI.

BACKGROUND: The efficacies of fresh frozen plasma and coagulation factor transfusion have been widely evaluated in trauma-induced coagulopathy management during the acute post-injury phase. However, the efficacy of red blood cell transfusion has not been adequately investigated in patients with severe trauma, and the optimal hemoglobin target level during the acute post-injury and resuscitation phases remains unclear. Therefore, this study aimed to examine whether a restrictive transfusion strategy was clinically non-inferior to a liberal transfusion strategy during the acute post-injury phase. METHODS: This cluster-randomized, crossover, non-inferiority multicenter trial was conducted at 22 tertiary emergency medical institutions in Japan and included adult patients with severe trauma at risk of major bleeding. The institutions were allocated a restrictive or liberal transfusion strategy (target hemoglobin levels: 7-9 or 10-12 g/dL, respectively). The strategies were applied to patients immediately after arrival at the emergency department. The primary outcome was 28-day survival after arrival at the emergency department. Secondary outcomes included transfusion volume, complication rates, and event-free days. The non-inferiority margin was set at 3%. RESULTS: The 28-day survival rates of patients in the restrictive (n = 216) and liberal (n = 195) strategy groups were 92.1% and 91.3%, respectively. The adjusted odds ratio for 28-day survival in the restrictive versus liberal strategy group was 1.02 (95% confidence interval: 0.49-2.13). Significant non-inferiority was not observed. Transfusion volumes and hemoglobin levels were lower in the restrictive strategy group than in the liberal strategy group. No between-group differences were noted in complication rates or event-free days. CONCLUSIONS: Although non-inferiority of the restrictive versus liberal transfusion strategy for 28-day survival was not statistically significant, the mortality and complication rates were similar between the groups. The restrictive transfusion strategy results in a lower transfusion volume. TRIAL REGISTRATION NUMBER: umin.ac.jp/ctr: UMIN000034405, registration date: 8 October 2018.
RESUMO
We report the case of a patient for whom surgical hemostasis of gastrointestinal bleeding due to a splenic artery pseudoaneurysm, which developed due to gastric ulcer penetration, was achieved with resuscitative endovascular balloon occlusion of the aorta without ischemia of organs including the spleen.
RESUMO
BACKGROUND: Acute kidney injury (AKI) after trauma is a major complication independently associated with a prolonged hospital stay and increased mortality. We previously reported that the prehospital systolic blood pressure (SBP) and early hospital arterial lactate level, along with specific cut-off values, show good performance in the early prediction of AKI using AUC-ROC [1]. The purpose of this study was to prospectively validate whether or not these parameters are predictive of newly occurring AKI after trauma. METHODS: This was a prospective review of trauma patients who were admitted to a single trauma center from January to December 2019. Patients who were <16 years old, who had burns, and who had chronic kidney disease were excluded. AKI was defined according to the Risk, Injury, Failure, Loss of the kidney function, and End-stage kidney disease (RIFLE) classification based on serum creatinine alone. Patients with a low prehospital SBP (≤126 mmHg) and high lactate levels (≥2.5 mmol/L) were defined as the high-risk group, and other patients were defined as the low-risk group. RESULTS: A total of 489 trauma patients were admitted to our center, of whom 403 were eligible for the study. The high-risk group consisted of 38 patients, and the low-risk group consisted of 365 patients. The incidence of severe AKI in Stage Injury and Failure was significantly higher in the high-risk group (5 patients, 13.2%) than in the low-risk group (7 patients, 1.9%), with an odds ratio of 7.75 and 95% confidence interval of 2.33-25.77. CONCLUSIONS: These predictors showed good performance in the early prediction of severe AKI after trauma. Early prediction of the high-risk groups for severe AKI after trauma prompting early treatment may help improve the prognosis of trauma patients.

PURPOSE: Decision making in management of blunt bowel and mesenteric injury (BBMI) is difficult. This study aimed to identify indicators for laparotomy and appropriate time intervals to surgery. METHODS: We retrospectively reviewed our hospital's trauma registry to identify patients with a diagnosis of BBMI from February 2011 to July 2017. Patients requiring therapeutic surgical treatment (OM group) were compared with those who did not (NOM group). Preoperative risk factors for surgery (with p < 0.1 by univariate analysis) were integrated in a multivariate logistic regression model. In the OM group, we identified relevant factors for time intervals to surgical interventions. RESULTS: Among 2808 trauma patients admitted to our hospital, 83 (3.0%) had bowel and mesenteric injury; 6 patients with penetrating trauma, 2 lethal, untreated cases, and 2 patients who underwent exploratory laparotomy were excluded. Finally, 73 patients (47 males), with a mean Injury Severity Score (ISS) of 23, were included. Results from univariate analysis identified three relevant factors between the OM and NOM groups: ISS score (p = 0.036), hemodynamic instability (p = 0.041), and free air (p = 0.0018). Multivariate analysis revealed one relevant factor, free air (p = 0.0002). Short intervals between hospital admission and intervention were associated with 7-day mortality (p = 0.029), hemodynamic instability (p = 0.0009), focused assessment with sonography for trauma positive (p < 0.0001), and mesenteric extravasation (p = 0.012). CONCLUSIONS: Early surgical intervention is essential in cases of hemodynamically unstable BBMI and bowel perforation with free air; nevertheless, it is associated with high mortality. We suggest that prompt transport along with early intervention could significantly lessen mortality.

PURPOSE: Pancreaticoduodenectomy (PD) following gastrectomy (TG) should be considered challenging even currently although its procedure and clinical value have been being standardized. Short- and long-term outcomes as well as standard reconstruction method following these procedures remain unclear. In order to clarify these issues, we reviewed worldwide English literature and 4 of our own cases of PD for patients with previous TG. METHODS: Clinicopathological variables of 11 cases of PD for patients with previous TG were evaluated. Seven of these 11 were abstracted from a review of worldwide English literature and 4 of 11 were our own cases. RESULTS: 3 cases was reconstructed using Y-limb made in previous TG and afferent loop syndrome (ALS) was observed in 2 of 3, in these cases whereas no cases of ALS were found in cases reconstructed using newly-made Y-limb. In cases where PD was indicated for cancer, early cancer death, defined as death related to cancer recurrence observed within 2 years after PD, was observed in 6 of 9 cases. Notably in cases of pancreatic cancer recurrent cancer was diagnosed within 1year after PD in 5 of 7 cases and 4 of these patients died of pancreatic cancer soon after recurrence. CONCLUSION: In cases of PD following TG, previously-made Y-limb should not be used for reconstruction following PD because of probable cause of previously-made Y-limb for ALS. Long-term outcomes of PD after TG seemed unsatisfactory notably in cases of pancreatic cancer and thus application of PD for patients with previous TG should be carefully decided until reasonable explanation for this dismal outcome is obtained.
RESUMO
We present a case of afferent loop syndrome (ALS) occurring after pancreaticoduodenectomy (PD) in a patient who had previously undergone total gastrectomy (TG), and review the English-language literature concerning reconstruction procedures following PD in patients who had undergone TG. The patient was a 69-year-old man who had undergone TG reconstruction by a Roux-en-Y method at age 58 years. The patient underwent PD for pancreas head adenocarcinoma. A jejunal limb previously made at the prior TG was used for pancreaticojejunostomy and hepaticojejunostomy. Despite normal patency of the hepaticojejunostomy, he suffered from repeated postoperative cholangitis which was brought on by ALS due to shortness of the jejunal limb (15 cm in length). We therefore performed receliotomy in which the hepaticojejunostomy was disconnected and reconstructed using a new Y limb 40-cm in length constructed in a double Roux-en-Y fashion. The refractory cholangitis resolved immediately after the receliotomy and did not recur. Review of the literature revealed the lack of any current consensus for a standard procedure for reconstruction following PD in patients who had previously undergone TG. This issue warrants further attention, particularly given the expected future increase in the number of PDs in patients with a history of gastric cancer.
