Trauma laparoscopy and the six w's: Why, where, who, when, what, and how?

Indocyanine green fluorescence-guided laparoscopic central pancreatectomy for complete pancreatic transection trauma: a rare case and literature review

Background

Pancreatic trauma is a rare solid organ injury. Conservative treatment is often indicated in patients with no pancreatic duct injury, while patients with high-grade pancreatic damage most often require surgical intervention. Laparoscopic central pancreatectomy (LCP) is a parenchyma-sparing approach and can prevent endocrine and exocrine insufficiency after pancreatic resection. Indocyanine green (ICG) fluoroscopy can help the surgeon assess the blood supply of the target organ.

Case presentation

The case we describe here is a 33-year-old male patient who was transferred to our hospital due to blunt abdominal trauma caused by a car accident. The patient was hemodynamically stable on admission and was diagnosed with isolated pancreatic trauma by a multidisciplinary team that included radiologists, emergency physicians, and pancreatic surgeons. The patient then underwent emergency laparoscopic central pancreatectomy, during which we used ICG fluoroscopy to assess the blood perfusion of the damaged pancreas to determine the extent of resection. The patient developed a biochemical fistula (grade A pancreatic fistula) after surgery, and no other intervention was performed except for continuous drainage. The patient was discharged on postoperative day 13. At the 3-month follow-up, the patient did not present any clinical manifestations of pancreatic endocrine and exocrine insufficiency.

Conclusion

To the best of our knowledge, there have been no reports of ICG-guided emergency LCP for blunt abdominal trauma. In selected patients, emergency LCP is feasible and should be supported by a multidisciplinary team and performed by an experienced pancreatic surgeon with advanced laparoscopic skills.

Role of laparoscopic surgery in managing hemodynamically stable abdominal trauma patients: a single level I trauma center, propensity score matching study

BACKGROUND

The role of laparoscopy in the treatment and diagnosis of penetrating thoraco-abdominal injury has been established. However, there is no clear consensus on the role of laparoscopy in blunt injury due to numerous reasons, such as concerns of missed injury and technical problems in treating various abdominal organs. This study aimed to determine the feasibility of laparoscopy and evaluate its safety in managing blunt and penetrating abdominal trauma.

METHODS

The medical records and Korean Trauma Data Base (KTDB) of patients who underwent abdominal surgery from January 2018 to December 2022 at a single level I center were collected. Patients were classified into a laparoscopy group and a laparotomy group. The laparoscopy groups were matched 1:1 with the laparotomy group by using propensity score matching (PSM). Patient demographics, injured organ and its grade, operative procedure, and postoperative outcomes were evaluated and compared between the two groups.

RESULTS

After propensity score matching, 128 patients were included. There was no significant imbalance in demographics between the two groups except sex. Injured organ and its grade showed no significant differences between the two groups except for the incidence of omentum. Small bowel and mesenteric repair were performed most often in both groups. Splenectomy, pancreatic surgery, duodenectomy, and liver resection were performed exclusively in the laparotomy group. Severe postoperative complication rate (3% vs. 20%: p = 0.004), length of stay in ICU (3.3 ± 3.2 days vs. 4.6 ± 3.7; p = 0.046), and operation time (93.9 ± 47.7 min vs. 112.8 ± 57.7; p = 0.046) were significantly lower in the laparoscopy group. The conversion rate was about 16%. There was no missed injury.

CONCLUSIONS

In hemodynamically stable abdominal trauma patients who sustained penetrating or blunt injury, laparoscopy is feasible and safe as a diagnostic and therapeutic modality in selected cohort of abdominal trauma.

Nationwide Trends in Utilization of Minimally Invasive Techniques for Blunt Abdominal Trauma

BACKGROUND

Despite increasing use of minimally invasive surgical (MIS) techniques for trauma, limited large-scale studies have evaluated trends, outcomes, and resource utilization at centers that utilize MIS modalities for blunt abdominal trauma.

METHODS

Operative adult admissions after blunt assault, falls, or vehicular collisions were tabulated from the 2016-2020 National Inpatient Sample. Patients who received diagnostic laparoscopy or other laparoscopic and robotic intervention were classified as MIS. Institutions with at least one MIS trauma operation in a year were defined as an MIS Performing Institution (MPI; rest: non-MPI). The primary endpoint was mortality, with secondary outcomes of reoperation, complication, postoperative length of stay (LOS), and hospitalization costs. Mixed regression models were used to determine the association of MPI status on the outcomes of interest.

RESULTS

Throughout the study period, the proportion of MIS operations and MPI significantly increased from 22.6 to 29.8% and 45.9 to 58.8%, respectively. Of an estimated 77,480 patients, 66.7% underwent care at MPI. After adjustment, MPI status was not associated with increased odds of mortality (adjusted odds ratio [AOR] 1.09, 95% confidence interval [CI] [.96,1.24]), reoperation (AOR 1.02, CI [.87,1.19]), or any of the tabulated complications. There was additionally no difference in adjusted LOS (β-.18, CI [-.85, +.49]) or costs (β+$1600, CI [-1600, +4800]), between MPI and non-MPI.

DISCUSSION

The use of MIS operations in blunt abdominal trauma has significantly increased, with performing centers experiencing no difference in mortality or resource utilization. Prospectively collected data on outcomes following MIS trauma surgery is necessary to elucidate appropriate applications.

To the point: Utility of laparoscopy for operative management of stabbing abdominal trauma

BACKGROUND

Algorithms for managing penetrating abdominal trauma are conflicting or vague regarding the role of laparoscopy. We hypothesized that laparoscopy is underutilized among hemodynamically stable patients with abdominal stab wounds.

METHODS

Trauma Quality Improvement Program data (2016-2019) were used to identify stable (SBP ≥110 and GCS ≥13) patients ≥16yrs with stab wounds and an abdominal procedure within 24hr of admission. Patients with a non-abdominal AIS ≥3 or missing outcome information were excluded. Patients were analyzed based on index procedure approach: open, therapeutic laparoscopy (LAP), or LAP-conversion to open (LCO). Center, clinical characteristics and outcomes were compared according to surgical approach and abdominal AIS using non-parametric analysis.

RESULTS

5984 patients met inclusion criteria with 7 ​% and 8 ​% receiving therapeutic LAP and LCO, respectively. The conversion rate for patients initially treated with LAP was 54 ​%. Compared to conversion or open, therapeutic LAP patients had better outcomes including shorter ICU and hospital stays and less infection complications, but were younger and less injured. Assessing by abdominal AIS eliminated ISS differences, meanwhile LAP patients still had shorter hospital stays. At time of admission, 45 ​% of open patients met criteria for initial LAP opportunity as indicated by comparable clinical presentation as therapeutic laparoscopy patients.

CONCLUSIONS

In hemodynamically stable patients, laparoscopy remains infrequently utilized despite its increasing inclusion in current guidelines. Additional opportunity exists for therapeutic laparoscopy in trauma, which appears to be a viable alternative to open surgery for select injuries from abdominal stab wounds.

The Role of Minimally Invasive Surgeries in Trauma

This article delves into the role of minimally invasive surgeries in trauma, specifically laparoscopy and video-assisted thoracic surgery (VATS). It discusses the benefits of laparoscopy over traditional laparotomy, including its accuracy in detecting peritoneal violation and intraperitoneal injuries caused by penetrating trauma. The article also explores the use of laparoscopy as an adjunct to nonoperative management of abdominal injuries and in cases of blunt trauma with unclear abdominal injuries. Furthermore, it highlights the benefits of VATS in diagnosing and treating thoracic injuries, such as traumatic diaphragmatic injuries, retained hematomas, and persistent pneumothorax.

Cesena guidelines: WSES consensus statement on laparoscopic-first approach to general surgery emergencies and abdominal trauma

BACKGROUND

Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma.

METHODS

This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement.

RESULTS

A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma.

CONCLUSIONS

The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Development and Validation of a Novel Hollow Viscus Injury Prediction Score for Abdominal Seatbelt Sign: A Pacific Coast Surgical Association Multicenter Study

BACKGROUND

High-quality CT can exclude hollow viscus injury (HVI) in patients with abdominal seatbelt sign (SBS) but performs poorly at identifying HVI. Delay in diagnosis of HVI has significant consequences necessitating timely identification.

STUDY DESIGN

This multicenter, prospective observational study conducted at 9 trauma centers between August 2020 and October 2021 included adult trauma patients with abdominal SBS who underwent abdominal CT before surgery. HVI was determined intraoperatively and physiologic, examination, laboratory, and imaging findings were collected. Least absolute shrinkage and selection operator- and probit regression-selected predictor variables and coefficients were used to assign integer points for the HVI score. Validation was performed by comparing the area under receiver operating curves (AUROC).

RESULTS

Analysis included 473 in the development set and 203 in the validation set. The HVI score includes initial systolic blood pressure <110 mmHg, abdominal tenderness, guarding, and select abdominal CT findings. The derivation set has an AUROC of 0.96, and the validation set has an AUROC of 0.91. The HVI score ranges from 0 to 17 with score 0 to 5 having an HVI risk of 0.03% to 5.36%, 6 to 9 having a risk of 10.65% to 44.1%, and 10 to 17 having a risk of 58.59% to 99.72%.

CONCLUSIONS

This multicenter study developed and validated a novel HVI score incorporating readily available physiologic, examination, and CT findings to risk stratify patients with an abdominal SBS. The HVI score can be used to guide decisions regarding management of a patient with an abdominal SBS and suspected HVI.

Introduction of Laparoscopy in an Urban High-Volume Sub-Saharan Trauma Centre

INTRODUCTION

Trauma is a major disease burden in low and middle-income countries like South Africa. Abdominal trauma is one of the leading reasons for emergency surgery. The standard of care for these patients is a laparotomy. In selected trauma patients, laparoscopy has both diagnostic and therapeutic usage. The trauma burden and the number of cases seen in a busy trauma unit make laparoscopy challenging.

AIM

We wanted to describe our journey with laparoscopy in the management of abdominal trauma in a busy urban trauma unit in Johannesburg, South Africa.

METHODS

We reviewed all trauma patients who underwent diagnostic laparoscopy (DL) or therapeutic laparoscopy (TL) between 01 January 2017 and 31 October 2020 for blunt and penetrating abdominal trauma. The demographic data, indications for laparoscopy, injuries identified, procedures performed, intraoperative laparoscopic complications, conversion to laparotomy, morbidity, and mortality were evaluated.

RESULTS

A total of 54 patients who had laparoscopy were included in the study. The median age was 29 years (IQR 25-25). Most injuries were penetrating 85.2% (n = 46/54) and 14.8% blunt trauma. Most patients were males, 94.4% (n = 51/54). Indications for laparoscopy included diaphragm evaluation (40.7%), pneumoperitoneum for evaluation of potential bowel injury (16.7%), free fluid with no evidence of solid organ injury (12.9%) and colostomy (5.5%). There were 8 (14.8%) cases converted to laparotomy. There were no missed injuries or mortality in the study group.

CONCLUSION

Laparoscopy in selected trauma patients is safe even in a busy trauma unit. It is associated with less morbidity and shortened hospital length of stay.

The role of laparoscopic splenectomy in traumatic splenic injury: a narrative review

INTRODUCTION

Splenic injuries are one of the commonest occurrences in abdominal trauma. Nonoperative management (NOM) is the treatment of choice in hemodynamically stable patients with low grade injuries in the absence of vascular injury on CT; however, in some cases, NOM can fail and surgery is required. Traditionally, splenectomy is performed via laparotomy but, recently, the use of laparoscopy is rapidly increasing because the numerous advantages it offers for selected trauma patients.

EVIDENCE ACQUISITION

A systematic review of the literature was performed through Medline for papers on the laparoscopic splenectomy (LS) in trauma patients, published from January 2006 to July 2022. The inclusion criteria were the study population consisted of hemodynamically stable adult patients treated with LS, as primary treatment or in case of complication or failure of NOM. The data extracted included gender, patient age, type of trauma, ISS, indication for LS and if LS was performed primary or secondary to NOM. The considered outcomes were operative time, length of stay, morbidity and mortality.

EVIDENCE SYNTHESIS

Eight papers were considered suitable for the study and all the articles were retrospective studies and only one of them was multicentered. A total of 202 patients were included in the study and all of these suffered splenic trauma and all patients were hemodynamically stable or responding to fluid resuscitation. Trauma mechanism was blunt in 92.9% of cases and penetrating in 7%. Twenty-one patients underwent LS after failure of angioembolization. Operative time of LS was reported in 6 papers and the mean was 130.7 mins. Length of stay was reported in 7 papers and the mean was 8.12 days. Overall morbidity was 7.7% and the postoperative mortality was cited in 6 articles with an overall percentage of 2.5%.

CONCLUSIONS

Laparoscopy should be considered a valid alternative to open surgery, in hemodynamically stable patients and when performed by an experienced surgeon, such as the minimally invasive trauma surgeon.

Characteristics of Laparoscopic Surgery for Trauma Patients and Risks of Conversion to Open Laparotomy

BACKGROUND

The discussion is ongoing about appropriate indications for laparoscopic surgery in trauma patients. As timing and risks of conversion to laparotomy remain unclear, we aimed to elucidate characteristics of and risks for conversion following laparoscopic surgery, using a nationwide database.

METHODS

A retrospective observational study was conducted, using Japanese Trauma Data Bank (2004-2018). We included adult trauma patients who underwent laparoscopic surgery as an initial surgical intervention. Conversion to laparotomy was defined as laparotomy at the initial surgery. Patient demographics, mechanism and severity of injury, injured organs, timing of surgery, and clinical outcomes were compared between patients with and without conversion. Risks for conversion were analyzed focusing on indications for laparoscopic surgery, after adjusting patient and institution characteristics.

RESULTS

Among 444 patients eligible for the study, 31 required conversions to laparotomy. The number of laparoscopic surgeries gradually increased over the study period (0.5-4.5% of trauma laparotomy), without changes in conversion rates (5-10%). Patients who underwent conversion had more severe abdominal injuries compared with those who did not (AIS 3 vs 2). While length of hospital stay and in-hospital mortality were comparable, abdominal complications were higher among patients with conversion (12.9 vs. 2.9%), particularly when laparoscopy was performed for peritonitis (OR, 22.08 [5.11-95.39]). A generalized estimating equation model adjusted patient background and identified hemoperitoneum and peritoneal penetration as risks for conversion (OR, 24.07 [7.35-78.75] and 8.26 [1.20- 56.75], respectively).

CONCLUSIONS

Trauma laparoscopy for hemoperitoneum and peritoneal penetration were associated with higher incidence of conversion to open laparotomy.

WSES guidelines on blunt and penetrating bowel injury: diagnosis, investigations, and treatment

The aim of this paper was to review the recent literature to create recommendations for the day-to-day diagnosis and surgical management of small bowel and colon injuries. Where knowledge gaps were identified, expert consensus was pursued during the 8th International Congress of the World Society of Emergency Surgery Annual (September 2021, Edinburgh). This process also aimed to guide future research.

Infectious outcomes after splenectomy for trauma, splenectomy for disease and splenectomy with distal pancreatectomy

Introduction

The spleen provides a unique immune function in its production of opsins directed against encapsulated bacteria. Splenectomy, therefore, increases the risk of infections in patients as well as post-operative complications. This study aims to assess the risk of post-operative complications within 5 years of splenectomy by indication for splenectomy: trauma, disease, or in association with a distal pancreatectomy for pancreatic disease. The relationship between vaccination and infectious outcomes was also investigated.

Methods

This study is a review of splenectomy cases between June 2005 and June 2015 at a single institution. Infection, splenectomy indication, and vaccination history were identified from electronic medical records and lab test confirmations. Data was analyzed using Student’s t test for continuous variables, the Mann–Whitney U test for ordinal variables, and a Chi-square/Fisher exact test for categorical variables.

Results

A total of 106 splenectomy patients were included: 35 traumatic (74% male) and 71 non-traumatic causes (42% male) with no significant difference in age. There were no statistical differences in complications during splenectomy and vaccination administration between the splenectomy indication groups: trauma, disease, and with distal pancreatectomy. There was a statistically significant higher infection rate within 5 years post-splenectomy in the non-traumatic vs traumatic group (42% vs 14.0%, p = 0.0040) with majority gastrointestinal (7/38) and respiratory (5/38) and surgical wound infections (3/38) observed in non-traumatic versus traumatic, respectively.

Conclusion

Results from data analysis show a statistically significant difference in rates of infection within 5 years post-operatively between traumatic versus non-traumatic indications for splenectomies, with the non-traumatic group experiencing a higher rate of infectious outcomes. The non-traumatic group included patients with disease and distal pancreatectomy indications. This suggests that patients who have non-traumatic causes may be at a higher risk of developing infections following splenectomy procedure. Additionally, vaccinations did not appear to have a protective effect.

Laparoscopy in the Evaluation of Blunt Abdominal Injury in Level-I and II Pediatric Trauma Centers

Introduction

An American College of Surgeons (ACS) Level-I (L-I) pediatric trauma center demonstrated successful laparoscopy without conversion to laparotomy in ∼65% of trauma cases. Prior reports have demonstrated differences in outcomes based on ACS level of trauma center. We sought to compare laparoscopy use for blunt abdominal trauma at L-I compared to Level-II (L-II) centers.

Methods

The Pediatric Trauma Quality Improvement Program was queried (2014-2016) for patients ≤16 years old who underwent any abdominal surgery. Bivariate analyses comparing patients undergoing abdominal surgery at ACS L-I and L-II centers were performed.

Results

970 patients underwent abdominal surgery with 14% using laparoscopy. Level-I centers had an increased rate of laparoscopy (15.6% vs 9.7%, P = .019 ); however they had a lower mean Injury Severity Score (16.2 vs 18.5, P = .002) compared to L-II centers. Level-I and L-II centers had similar length of stay ventilator days, and SSIs (all P > .05).

Conclusion

While use of laparoscopy for pediatric trauma remains low, there was increased use at L-I compared to L-II centers with no difference in LOS or SSIs. Future studies are needed to elucidate which pediatric trauma patients benefit from laparoscopic surgery.

Abdominal Self-Stabbing: An Uncommon Type of Sharp Abdominal Trauma

Abdominal self-stabbing, a type of sharp abdominal trauma, is a rare form of attempted suicide. Such cases are not commonly seen in the emergency department, but a prompt and well-reasoned decision is essential in the management of these patients. We report a case of a SI-ASW and a literature review to show the management of the aforementioned condition.

Atraumatic Splenic Rupture in a SARS-CoV-2 Patient: Case Report and Review of Literature

Splenic rupture in the absence of trauma or previously diagnosed disease is rare. Due to the delay of diagnosis and treatment, this is a potentially life-threatening condition. We report a case of atraumatic splenic rupture in a SARS-CoV-2 patient. This report is of particular interest as it first identifies SARS-CoV-2 infection as a possible cause of spontaneous rupture of the spleen. A 46-year-old Caucasian woman presented at the emergency department pale and sweaty, complaining of syncopal episodes, tachycardia, hypotension, diarrhea, intense abdominal pain, diffuse arthromyalgia, and fever from the day before. RT-PCR was positive for SARS-CoV-2 infection. CT scan demonstrated extensive hemoperitoneum due to rupture of the splenic capsule. The patient required an emergency open splenectomy because of an unresponsive hemorrhagic shock. At the end of the surgery, the patient was relocated to a COVID-19 dedicated facility. COVID-19 is a new disease of which all manifestations are not yet known. Inpatients affected by SARS-CoV-2 infection with abdominal pain and spontaneous splenic rupture should be considered to avoid a delayed diagnosis.

The Efficacy and Safety of Laparoscopy for Blunt Abdominal Trauma: A Systematic Review and Meta-Analysis

The efficacy and safety of laparoscopy for blunt trauma remain controversial. This systemic review and meta-analysis aimed to evaluate the usefulness of laparoscopy in blunt trauma. The PubMed, EMBASE, and Cochrane databases were searched up to 23 February 2021. Meta-analyses were performed using odds ratios (ORs), standardized mean differences (SMDs), and overall proportions. Overall, 19 studies with a total of 1520 patients were included. All patients were hemodynamically stable. In the laparoscopy group, meta-analysis showed lesser blood loss (SMD −0.28, 95% confidence interval (CI) −0.51 to −0.05, I² = 62%) and shorter hospital stay (SMD −0.67, 95% CI −0.90 to −0.43, I² = 47%) compared with the laparotomy group. Pooled prevalence of missed injury (0.003 (95% CI 0 to 0.023), I² = 0%), nontherapeutic laparotomy (0.004 (95% CI 0.001 to 0.026), I² = 0%), and mortality (0.021 (95% CI 0.010 to 0.043), I² = 0%) were very low in blunt trauma. In subgroup analysis, recently published studies (2011–present) showed lesser conversion rate (0.115 (95% CI 0.067 to 0.190) vs. 0.391 (95% CI 0.247 to 0.556), test for subgroup difference: p < 0.01). This meta-analysis suggests that laparoscopy is a safe and feasible option in hemodynamic stable patients with blunt abdominal trauma.

Evaluation of Lung Contusion, Associated Injuries, and Outcome in a Major Trauma Center in Shiraz, Southern Iran

Objective

Blunt chest trauma as one of the most common injuries in trauma cases can cause significant morbidity and mortality. The purpose of this study was to determine the clinical course of traumatic injuries with an initial diagnosis of a pulmonary contusion in patients.

Method

In this retrospective study, we evaluated the demographic and clinical features of patients who were referred to a major trauma center in southern Iran. In our study, patients were enrolled with the diagnosis of pulmonary contusion. All included patients were above 16 years of age, with an initial CT scan in favor of pulmonary contusion, while patients not being hospitalized for more than 48 hours were excluded from the study.

Results

Among the 434 patients included in our study, 366 (84%) were male and the mean age was 41.17 (SD = 17.89). Among them, the majority (80.4%) had right side lung contusion and 47 patients (10.8%) had right rib fracture. The most common injuries were head and neck injury (56.9%) and limbs (30%). In 25% of cases, pulmonary contusion was associated with pneumothorax and 15.8% with hemothorax. Also, 49.6% of patients were transferred to the ICU. The mortality rate in our study was 15.2% (n = 66).

Conclusion

Although recent advances in pulmonary care and ventilator management have been achieved, there is still considerable morbidity and mortality associated with this condition. Therefore, there is a need to provide a national guideline based on native patient information for better management.

Laparoscopic splenectomy as a definitive management option for high-grade traumatic splenic injury when non operative management is not feasible or failed: a 5-year experience from a level one trauma center with minimally invasive surgery expertise

Technique, indications and outcomes of laparoscopic splenectomy in stable trauma patients have not been well described yet. All hemodynamically non-compromised abdominal trauma patients who underwent splenectomy from 1/2013 to 12/2017 at our Level 1 trauma center were included. Demographic and clinical data were collected and analysed with per-protocol and an intention-to-treat comparison between open vs laparoscopic groups. 49 splenectomies were performed (16 laparoscopic, 33 open). Among the laparoscopic group, 81% were successfully completed laparoscopically. Laparoscopy was associated with a higher incidence of concomitant surgical procedures (p 0.016), longer operative times, but a significantly faster return of bowel function and oral diet without reoperations. No significant differences were demonstrated in morbidity, mortality, length of stay, or long-term complications, although laparoscopic had lower surgical site infection (0 vs 21%).The isolated splenic injury sub-analysis included 25 splenectomies,76% (19) open and 24% (6) laparoscopic and confirmed reduction in post-operative morbidity (40 vs 57%), blood transfusion (0 vs 48%), ICU admission (20 vs 57%) and overall LOS (7 vs 9 days) in the laparoscopic group. Laparoscopic splenectomy is a safe and effective technique for hemodynamically stable patients with splenic trauma and may represent an advantageous alternative to open splenectomy in terms of post-operative recovery and morbidity.

The GERtality Score: The Development of a Simple Tool to Help Predict in-Hospital Mortality in Geriatric Trauma Patients

Feasible and predictive scoring systems for severely injured geriatric patients are lacking. Therefore, the aim of this study was to develop a scoring system for the prediction of in-hospital mortality in severely injured geriatric trauma patients. The TraumaRegister DGU^® (TR-DGU) was utilized. European geriatric patients (≥65 years) admitted between 2008 and 2017 were included. Relevant patient variables were implemented in the GERtality score. By conducting a receiver operating characteristic (ROC) analysis, a comparison with the Geriatric Trauma Outcome Score (GTOS) and the Revised Injury Severity Classification II (RISC-II) Score was performed. A total of 58,055 geriatric trauma patients (mean age: 77 years) were included. Univariable analysis led to the following variables: age ≥ 80 years, need for packed red blood cells (PRBC) transfusion prior to intensive care unit (ICU), American Society of Anesthesiologists (ASA) score ≥ 3, Glasgow Coma Scale (GCS) ≤ 13, Abbreviated Injury Scale (AIS) in any body region ≥ 4. The maximum GERtality score was 5 points. A mortality rate of 72.4% was calculated in patients with the maximum GERtality score. Mortality rates of 65.1 and 47.5% were encountered in patients with GERtality scores of 4 and 3 points, respectively. The area under the curve (AUC) of the novel GERtality score was 0.803 (GTOS: 0.784; RISC-II: 0.879). The novel GERtality score is a simple and feasible score that enables an adequate prediction of the probability of mortality in polytraumatized geriatric patients by using only five specific parameters.

Laparoscopic Management of Blunt and Penetrating Abdominal Trauma: A Single-Center Experience and Review of the Literature

Introduction: Trauma is a leading cause of death in young patients. The prevalence of blunt and penetrating trauma varies widely across the globe. Similarly, the global experience with laparoscopy in trauma patients also varies. There is a growing body of evidence to suggest that laparoscopy is feasible in trauma patients. We sought to contribute to these data by reporting our experience with laparoscopic management of blunt and penetrating trauma in a Belgian center. Materials and Methods: We retrospectively collected data on all trauma patients admitted to the Saint-Pierre University Hospital in Brussels, Belgium, over the 4-year period from January 2014 to December 2017. Hospital records for patients subjected to exploratory laparoscopy were retrospectively reviewed, and a descriptive analysis was reported. Results: There were 26 patients at a mean age of 40 years treated with laparoscopic exploration for injuries from blunt trauma (7), stab wounds (14), and gunshot injuries (5). The median interval between the arrival at the emergency unit and diagnostic laparoscopy was 175 minutes (range: 27-1440), and the median duration of operation was 119 minutes (range: 8-300). In all patients who underwent laparoscopy for trauma, there were 27% overall morbidity, no mortality, 11% reoperation rate, 7.4% conversions, and 19% incidence of negative laparoscopy. The median intensive care unit stay was 3 days (range: 0-41), and median total hospital stay was 7 days (range: 2-78). Conclusions: Laparoscopy is a safe, feasible, and effective tool in the surgical armamentarium to treat hemodynamically stable patients with blunt and penetrating abdominal trauma. It allows complete and thorough evaluation of intra-abdominal viscera, reduces the incidence of nontherapeutic operations, and allows therapeutic intervention to repair a variety of injuries. However, it requires appropriate surgeon training and experience with advanced laparoscopic techniques to ensure good outcomes.

Laparoscopic splenectomy after trauma: Who, when and how. A systematic review

Importance:

A deep knowledge of the indication for laparoscopic splenectomy (LS) in trauma case can lead trauma surgeon to offer in a wider number of situations a minimally invasive approach to a common injuries.

Objective:

To present and review the advantages and disadvantages of laparoscopic approach for spleen trauma and to identify patient whose can benefit from a minimally invasive approach versus patient that need open surgery to assess the whole severity of trauma.

Evidence Review:

A systematic review was performed according to the PRISMA statement in order to identify articles reporting LS after trauma. A literature search was performed through MEDLINE (through PubMed), Embase and Google Scholar from January 1990 to December 2018. Studies conducted on animals were not considered. All other laparoscopic procedures for spleen trauma were excluded.

Results:

Nineteen articles were included in this study, reporting 212 LS after trauma. The most study includes blunt trauma patient. All LS were performed in haemodynamically stable patient. Post-operative complications were reported in all articles with a median post-operative morbidity rate of 30 patients (14.01%), including 16 (7.5%) post-operative deaths.

Conclusions and Relevance:

This article reports the feasibility and safety of a minimally invasive approach for common trauma injuries which can help non-advanced laparoscopic skill trauma surgeon to develop the best indication to when to adopt this kind of approach.

Laparoscopic surgery for splenic injuries in the era of non-operative management: current status and future perspectives

The spleen is one of the organs most commonly injured by blunt abdominal trauma. It plays an important role in immune response to infections, especially those sustained by encapsulated bacteria. Nonoperative management (NOM), comprising clinical and radiological observation with or without angioembolization, is the treatment of choice for traumatic splenic injury in patients who are hemodynamically stable. However, this strategy carries a risk of failure, especially for high-grade injuries. No clear predictors of failure have been identified, but minimally invasive surgery for splenic injury is gaining popularity. Laparoscopic surgery has been proposed as an alternative to open surgery for hemodynamically stable patients who require surgery, such as after failed NOM. We reviewed research articles on laparoscopic surgery for hemodynamically stable patients with splenic trauma to explore the current knowledge about this topic. After presenting an overview of the treatments for splenic trauma and the immunological function of the spleen, we try to identify the future indications for laparoscopic surgery in the era of NOM.

Is the minimally invasive trauma surgeon the next (r)evolution of trauma surgery? Indications and outcomes of diagnostic and therapeutic trauma laparoscopy in a level 1 trauma centre

The aim of this study was to evaluate the trend in use, feasibility and safety of laparoscopy in a single level 1 European trauma centre. Laparoscopy in abdominal trauma is gaining acceptance as a diagnostic and a therapeutic tool as it reduces surgical invasiveness and may reduce post-operative morbidity. All trauma patients who underwent a laparoscopic procedure between January 2013 and December 2017 were retrospectively analysed. A sub-analysis of isolated abdominal trauma was also performed. There has been a significant increase in the use of this technique in the considered time period. A total of 40 patients were included in the study: 17 diagnostic laparoscopies and overall 32 therapeutic laparoscopies. Conversion rate was 15%. All patients were hemodynamically stable. The majority of patients were younger than 60 years, with an ASA score of I-II and sustained a blunt trauma. Mean ISS score was 17. Colon and diaphragm were the most commonly laparoscopically diagnosed injuries, while splenectomy was the most common operation. The average operating time was 106 min. There were no missed injuries, no SSI, no re-interventions and no mortality related to the surgical procedure. The average length of stay was 14 days. No significant difference was found in the isolated abdominal trauma group. Laparoscopy is an emergent safe and effective technique for both diagnostic and therapeutic purposes in selected stable abdominal penetrating or blunt trauma patients. However, these results need to be put in relation with the level of the centre and the expertise of the surgeon.

Early management of severe abdominal trauma

OBJECTIVE

To develop French guidelines on the management of patients with severe abdominal trauma.

DESIGN

A consensus committee of 20 experts from the French Society of Anaesthesiology and Critical Care Medicine (Société française d'anesthésie et de réanimation, SFAR), the French Society of Emergency Medicine (Société française de médecine d'urgence, SFMU), the French Society of Urology (Société française d'urologie, SFU) and from the French Association of Surgery (Association française de chirurgie, AFC), the Val-de-Grâce School (École du Val-De-Grâce, EVG) and the Federation for Interventional Radiology (Fédération de radiologie interventionnelle, FRI-SFR) was convened. Declaration of all conflicts of interest (COI) policy by all participants was mandatory throughout the development of the guidelines. The entire guideline process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system for assessment of the available level of evidence with particular emphasis to avoid formulating strong recommendations in the absence of high level. Some recommendations were left ungraded.

METHODS

The guidelines are divided in diagnostic and, therapeutic strategy and early surveillance. All questions were formulated according to Population, Intervention, Comparison, and Outcomes (PICO) format. The panel focused on three questions for diagnostic strategy: (1) What is the diagnostic performance of clinical signs to suggest abdominal injury in trauma patients? (2) Suspecting abdominal trauma, what is the diagnostic performance of prehospital FAST (Focused Abdominal Sonography for Trauma) to rule in abdominal injury and guide the prehospital triage of the patient? and (3) When suspecting abdominal trauma, does carrying out a contrast enhanced thoraco-abdominal CT scan allow identification of abdominal injuries and reduction of mortality? Four questions dealt with therapeutic strategy: (1) After severe abdominal trauma, does immediate laparotomy reduce morbidity and mortality? (2) Does a "damage control surgery" strategy decrease morbidity and mortality in patients with a severe abdominal trauma? (3) Does a laparoscopic approach in patients with abdominal trauma decrease mortality or morbidity? and (4) Does non-operative management of patients with abdominal trauma without bleeding reduce mortality and morbidity? Finally, one question was formulated regarding the early monitoring of these patients: In case of severe abdominal trauma, which kind of initial monitoring does allow to reduce the morbi-mortality? The analysis of the literature and the recommendations were conducted following the GRADE® methodology.

RESULTS

The SFAR/SFMU Guideline panel provided 15 statements on early management of severe abdominal trauma. After three rounds of discussion and various amendments, a strong agreement was reached for 100% of recommendations. Of these recommendations, five have a high level of evidence (Grade 1±), six have a low level of evidence (Grade 2±) and four are expert judgments. Finally, no recommendation was provided for one question.

CONCLUSIONS

Substantial agreement exists among experts regarding many strong recommendations for the best early management of severe abdominal trauma.

"Pop in a scope": attempt to decrease the rate of unnecessary nontherapeutic laparotomies in hemodynamically stable patients with thoracoabdominal penetrating injuries

BACKGROUND

Management of patients with thoracoabdominal penetrating injuries is challenging. Thoracoabdominal penetrating trauma may harbor hollow viscus injuries in both thoracic and abdominal cavities and occult diaphragmatic lesions. While radiological tests show poor diagnostic performance in these situations, evaluation by laparoscopy is highly sensitive and specific. Furthermore, minimally invasive surgery may avoid unnecessary laparotomies, despite concerns regarding complication and missed injury rates. The objective of the present study is to evaluate the diagnostic and therapeutic performance of laparoscopy in stable patients with thoracoabdominal penetrating injuries.

METHODS

Retrospective analysis of hemodynamically stable patients with thoracoabdominal penetrating wounds was managed by laparoscopy. We collected data regarding the profile of the patients, the presence of diaphragmatic injury, perioperative complications, and the conversion rate. Preoperative imaging tests were compared to laparoscopy in terms of diagnostic accuracy.

RESULTS

Thirty-one patients were included, and 26 (84%) were victims of a stab wound. Mean age was 32 years. Ninety-three percent were male. Diaphragmatic lesions were present in 18 patients (58%), and 13 (42%) had associated injuries. There were no missed injuries and no conversions. Radiography and computerized tomography yielded an accuracy of 52% and 75%, respectively.

CONCLUSION

Laparoscopy is a safe diagnostic and therapeutic procedure in stable patients with thoracoabdominal penetrating wound, with low complication rate, and may avoid unnecessary laparotomies. The poor diagnostic performance of preoperative imaging exams supports routine laparoscopic evaluation of the diaphragm to exclude injuries in these patients.
