Non-operative management for abdominal solidorgan injuries: A literature review

Epidemiological profile of patients undergoing non-operative management of solid organ injury and associated factors with mortality

INTRODUCTION

Trauma primarily affects the economically active population, causing social and economic impact. The non-operative management of solid organ injuries aims to preserve organ function, reducing the morbidity and mortality associated with surgical interventions. The aim of study was to demonstrate the epidemiological profile of patients undergoing non-operative management in a trauma hospital and to evaluate factors associated with mortality in these patients.

METHODS

This is a historical cohort of patients undergoing non-operative management for solid organ injuries at a Brazilian trauma reference hospital between 2018 and 2022. Included were patients with blunt and penetrating trauma, analyzing epidemiological characteristics, blood transfusion, and association with the need for surgical intervention.

RESULTS

A total of 365 patients were included in the study. Three hundred and forty-three patients were discharged (93.97%), and the success rate of non-operative treatment was 84.6%. There was an association between mortality and the following associated injuries: hemothorax, sternal fracture, aortic dissection, and traumatic brain injury. There was an association between the need for transfusion and surgical intervention. Thirty-eight patients required some form of surgical intervention.

CONCLUSION

The profile of patients undergoing non-operative treatment consists of young men who are victims of blunt trauma. Non-operative treatment is safe and has a high success rate.

Evaluation of management of CT scan proved solid organ injury in blunt injury abdomen-a prospective study

BACKGROUND

Trauma especially road traffic injury is one of the major health-related issues throughout the world, especially in developing countries like India (Mattox 2022). Solid organ injury is the most common cause of morbidity and mortality in patients with blunt abdominal trauma. The non-operative management (NOM) is being consistently followed for hemodynamically stable patients with respect to solid organ injuries. This study aims to provide an evidence base for management modalities of solid organ injuries in blunt abdominal trauma.

AIM

The aim of this study is to evaluate the effectiveness of various treatment modalities for solid organ injury in blunt abdominal trauma.

OBJECTIVES

Evaluating the characteristics of blunt abdominal injury with respect to age and gender; distribution, mode of injury, most common organ injured, and severity of injury; effect of delay in getting treatment on the management outcome for patients with solid organ injury; evaluating the various modalities of treatment of CT-proven solid organ injury; incidence of complications in different modes of treatment.

METHODS

All patients aged more than 18 years and suffering from CT-proven solid organ injury secondary to blunt abdominal trauma between February 2021 and September 2022 were included in this prospective observational study. Sixty-five patients were enrolled in the study after meeting the inclusion criteria. Details such as age, gender, mechanism of injury, the time between injury to first hospital contact, presenting complaints, organ and grade of injury, Revised Trauma Score (RTS), Trauma Score and Injury Severity Score (TRISS), management, and outcomes were collected using self-designed pro forma and analyzed. Different modalities of treatment were evaluated and patients undergoing operative and non-operative management were compared. Patients in whom non-operative management failed were compared with patients with successful non-operative management.

RESULTS

The mean age of patients involved were 36.8 years with a male:female ratio of 7.125:1 and the most common age group affected being between 21 and 30 years. The most common mode of injury was noted to be road traffic accidents (72.3%). The most common presenting complaints were abdominal pain (64.6%) followed by chest pain (29.2%) and vomiting (13.8%). There was no significant relationship between latent period and type of intervention or failure of non-operative management. FAST positivity rate was noted to be 92.3%. Chronic alcoholism and bronchial asthma were significant predictors for patients undergoing upfront surgery (p = 0.003 and 0.006 respectively). The presence of pelvic and spine injury was statistically significant for predicting mortality in polytrauma patients (p = 0.003). Concurrent adrenal injury was found in 24.6% of patients but was not related to failure of non-operative management or mortality. RTS significantly predicts the multitude of organ involvement (p = 0.015). The liver was the most common organ injured (60%) followed by the spleen (52.3%) and the kidney (20%). The liver and the spleen (9.2%) were noted to be the most common organ combination involved. No specific organ or organ injury combination was noted to predict failure of non-operative management or mortality. But the multitude of organ involvement was statistically significant for predicting patients undergoing upfront surgery (p = 0.011). Out of 65 patients enrolled in the study, 7 patients (10.8%) underwent immediate surgery, and 58 patients (89.2%) underwent non-operative management. Among the 68 chosen for non-operative management, 6 patients (9.2%) failed non-operative management and 52 patients (80%) had success of non-operative management. A significant drop in hemoglobin (83.3%) on day 1 (66.6%) was seen to be the commonest reason for failure of non-operative management. The spleen was noted to be the most commonly involved organ intra-operatively (61.5%) followed by the liver (30.8%). Concordance between pre-operative and intra-operative grading of organ injuries was highest for liver and kidney injuries (100%) and lowest for pancreatic injuries (0%). Requirement of blood transfusion and liver injuries were significant factors for failure of non-operative management (p = 0.012 and 0.045 respectively). The presence of pancreatic leak was significant between the non-operated patients and patients operated upfront (p = 0.003). Mortality was noted to be 10.8% (7 patients) in our study.

CONCLUSION

Solid organ injury in blunt abdominal trauma is an important cause of morbidity and mortality. RTS was noted to be a good predictor for solid organ injury in blunt abdominal trauma. Pancreatic injuries are notorious for being under-staged on CT findings; hence, the need arises for multimodality imaging for suspected pancreatic injuries. Non-operative management is a successful modality of treatment for majority of patients suffering from multiple solid organ injuries in blunt abdominal trauma provided serial close monitoring of patient's clinical signs and hemoglobin is instituted along with the presence of an emergency surgery team.

Pediatric Blunt Splenic Trauma: Disparities in Management and Outcomes

INTRODUCTION

While nonoperative management has become widely accepted, whether nonoperative management of blunt splenic trauma is standardized across pediatric trauma centers and different racial groups warrants further investigation. Using the National Trauma Database, the purpose of this study was to quantify the differences in the management of pediatric splenic trauma across different pediatric trauma centers, with respect to injury severity, race, ethnicity, and insurance.

METHODS

Patients under 20 y of age with blunt splenic trauma reported to the 2018 and 2019 National Trauma Data Bank were identified. Primary outcomes were splenectomy, embolization, transfusion, mortality, injury severity score (ISS), and length of hospital stay (LOS) and length of intensive care unit stay. Continuous data and categorical data were analyzed using ANOVA and Chi-squared test, respectively. Nearest 1:1 neighbor matching was performed between minority patients and White patients. P < 0.05 for all comparative analyses was considered statistically significant.

RESULTS

Of the total cohort (n = 1919), 70.3% identified as White, while 21.6% identified as Black or Hispanic. The mortality rate was 0.3%. Among different race categories, the frequency of spleen embolization (P = 0.99), splenectomy (P = 0.99), blood transfusion (P = 1), and mortality (P = 1), were not significantly different. After controlling for ISS and age with propensity score matching, the mean hospital LOS remained significantly higher in minority patients, with a mean of 5.44 d compared to 4.72 d (P = 0.05). Mean length of intensive care unit stay was not significantly different after propensity matching, with a mean of 1.79 d and 1.56 spent in the ICU for minority and White patients respectively (P = 0.17). While propensity score matching preserved statistical significance, the ISS for the minority group remained 1.12 times higher than the ISS of the Caucasian group. There was no statistically significant difference among races with respect to different payment methods and insurance status, although Black and Hispanic patients were proportionally underinsured.

CONCLUSIONS

While minority patients had a relatively higher number of operative interventions and longer hospital and ICU stays, after propensity score matching, mean ISS remained higher in the minority group. Our findings suggest that injury severity is likely to influence the difference in LOS between the two groups. Furthermore, our data highlight how nonoperative management is not standardized across pediatric trauma centers.

A systematic review assessing incorporation of prophylactic splenic artery embolisation (pSAE) into trauma guidelines for the management of high-grade splenic injury

BACKGROUND

Splenic artery embolisation (SAE) has become a vital strategy in the modern landscape of multidisciplinary trauma care, improving splenic salvage rates in patients with high-grade injury. However, due to a lack of prospective data there remains contention amongst stakeholders as to whether SAE should be performed at the time of presentation (prophylactic or pSAE), or whether patients should be observed, and SAE only used only if a patient re-bleeds. This systematic review aimed to assess published practice management guidelines which recommend pSAE, stratified according to their quality.

METHODS

The study was registered and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Medline, PubMed, Cochrane, Embase, and Google Scholar were searched by the study authors. Identified guidelines were graded according to the Appraisal of Guidelines Research and Evaluation II (AGREE-II) instrument.

RESULTS

Database and internet searches identified 1006 results. After applying exclusion criteria, 28 guidelines were included. The use of pSAE was recommended in 15 guidelines (54%). This included 6 out of 9 guidelines that were high quality (66.7%), 4 out of 9 guidelines that were moderate quality (44.4%), and 3 out of 10 (30%) guidelines that were low quality, p = 0.275.

CONCLUSIONS

This systematic review showed that recommendation of pSAE is more common in guidelines which are of high quality. However, there is vast heterogeneity of recommended practice guidelines, likely based on individual trauma systems rather than the available evidence. This reflects biases with interpretation of data and lack of multidisciplinary system inputs, including from interventional radiologists.

Conservative management of multi-trauma induced peritonitis: Experience, outcomes, and indications

BACKGROUND

The concept of mandatory laparotomy in treating traumatic peritonitis has been increasingly questioned recently.

AIM

To summarize and share the experience of conservative treatment of patients with multi-trauma induced peritonitis.

METHODS

A retrospective review was performed on patients with multiple injury induced traumatic peritonitis.

RESULTS

A total of 184 patients with multiple injury induced traumatic peritonitis were reviewed. 46 of them underwent conservative treatment. None of the 46 patients with conservative treatment switched to surgical treatment, and all of them were cured and discharged after successful conservative treatment. No significant abnormal findings were observed at regular follow-up after discharge.

CONCLUSION

Conservative management is safe, effective, feasible, and beneficial in hemodynamically stable patients with traumatic peritonitis if there is no definite evidence of severe abdominal visceral organ injury.

Non-Operative Management of Polytraumatized Patients: Body Imaging beyond CT

In the transition from the operative to the conservative approach for the polytraumatized patients who undergo blunt trauma, diagnostic imaging has assumed a pivotal role, currently offering various opportunities, particularly in the follow-up of these patients. The choice of the most suitable imaging method in this setting mainly depends on the injury complications we are looking for, the patient conditions (mobilization, cooperation, medications, allergies and age), the biological invasiveness, and the availability of each imaging method. Computed Tomography (CT) represents the “standard” imaging technique in the polytraumatized patient due to the high diagnostic performance when a correct imaging protocol is adopted, despite suffering from invasiveness due to radiation dose and intravenous contrast agent administration. Ultrasound (US) is a readily available technology, cheap, bedside performable and integrable with intravenous contrast agent (Contrast enhanced US—CEUS) to enhance the diagnostic performance, but it may suffer particularly from limited panoramicity and operator dependance. Magnetic Resonance (MR), until now, has been adopted in specific contexts, such as biliopancreatic injuries, but in recent experiences, it showed a great potential in the follow-up of polytraumatized patients; however, its availability may be limited in some context, and there are specific contraindications, such as as claustrophobia and the presence non-MR compatible devices. In this article, the role of each imaging method in the body-imaging follow-up of adult polytraumatized patients will be reviewed, enhancing the value of integrated imaging, as shown in several cases from our experience.

Successful non-operative management of multiple intra-abdominal solid organ injury after blunt abdominal trauma: a case report

Injuries to the solid abdominal viscera are common after blunt trauma. The success of non-operative management of these injuries has led to recent extensions of this approach to managing higher-grade, more complicated injuries that are typically treated operatively. We reported a 19-year-old male who presented with abdominal pain and gross hematuria during the late hours due to a motor vehicle accident. Abdominal computed tomography scan revealed moderate hemoperitoneum, extensively devascularized spleen with laceration extending into the hilum, multiple tears in the left kidney extended to the hilum, and large perinephric hematoma suggestive of Grade V injuries (shattered spleen and left kidney). We managed the patient non-operatively until he improved and became ready for discharge from the hospital in stable good health status. In conclusion, this case brings to light a unique instance where severe grade multiple solid organ injury was successfully managed with a conservative approach.
