Laparoscopy for Trauma and the Changes in its Use From 1990 to 2016: A Current Systematic Review and Meta-Analysis

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.

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.

The Role of Diagnostic Laparoscopy in the Evaluation of Abdominal Trauma Patients: A Trauma Quality Improvement Program Study

PURPOSE

We aimed to identify factors related to delayed intervention in abdominal trauma patients who underwent diagnostic laparoscopy using a nationwide databank.

METHODS

From 2017 to 2019, abdominal trauma patients who underwent diagnostic laparoscopy were retrospectively evaluated using the Trauma Quality Improvement Program. Patients who underwent delayed interventions after a primary diagnostic laparoscopy were compared with those who did not. Factors associated with poor outcomes that are usually correlated with overlooked injuries and delayed interventions were also analyzed.

RESULTS

Of the 5221 studied patients, 4682 (89.7%) underwent inspection without any intervention. Only 48 (0.9%) patients underwent delayed interventions after primary laparoscopy. Compared with patients receiving immediate interventions during primary diagnostic laparoscopy, patients receiving delayed interventions were more likely to have small intestine injuries (58.3% vs. 28.3%, p < 0.001). Among patients with hollow viscus injuries, a significantly higher probability of overlooked injuries that required delayed intervention was observed in patients with small intestine injuries (small intestine injury: 16.8%; gastric injury: 2.5%; large intestine injury: 5.2%). However, delayed small intestine repair did not significantly affect the risk of surgical site infection (SSI) (p = 0.249), acute kidney injury (AKI) (p = 0.998), or hospital length of stay (LOS) (p = 0.053). In contrast, significantly positive relationships between delayed large intestine repair and poor outcomes were observed (SSI, odds ratio = 19.544, p = 0.021; AKI, odds ratio = 27.368, p < 0.001; LOS, β = 13.541, p < 0.001).

CONCLUSIONS

Most examinations and interventions (near 90%) were successful during primary laparoscopy for abdominal trauma patients. Small intestine injuries were easily overlooked. Delayed small intestine repair-related poor outcomes were not observed.

The role of laparoscopy in closed abdominal injury

Objective

To investigate the effect of laparoscopy on the diagnosis and treatment of closed abdominal injury.

Methods

A total of 26 patients with closed abdominal injury admitted to our hospital from January 2016 to January 2019 were searched. All patients were treated by laparoscopy. All patient reports were made with the informed consent of the patients.

Results

All patients were diagnosed clearly during operation. Among them, there were 3 cases of gastric perforation, 2 cases of liver rupture, 13 cases of spleen rupture, 3 cases of small intestine rupture, 1 case of liver round ligament laceration, 2 cases of small mesenteric vascular laceration, 1 case of colon liver mesenteric laceration, and 1 case of retroperitoneal hematoma. Of the 26 patients in this group, 23 (88.5%) completed laparoscopically or laparoscopically assisted; 5 cases (19.3%) only performed laparoscopic exploration without special treatment, and 3 cases (11.5%) switched to laparotomy. The blood loss was 50-2000 ml (mean 500 ml), and the operative time was 60-180min (mean 128min). The length of hospital stay was 3-21 d (mean 9 d). There were no complications or deaths related to laparoscopy in the whole group. Conclusion Laparoscopic technique has the advantages of less trauma, high diagnosis rate and fast recovery. It can also be used for surgical treatment in the diagnosis and treatment of closed abdominal injury, so as to achieve the purpose of comprehensive diagnosis and treatment. The limitations of laparoscopy should also be noted.

Utilization of deep neuromuscular blockade combined with reduced abdominal pressure in laparoscopic radical gastrectomy for gastric cancer: An academic perspective

BACKGROUND

Few studies have examined the specific efficacy of deep neuromuscular blockade (NMB) combined with pneumoperitoneal pressure reduction in laparoscopic radical gastrectomy (LRG) in the elderly.

AIM

To investigate the application effect of deep neuromuscular blockade (NMB) combined with reduced pneumoperitoneum pressure in LRG for gastric cancer (GC) in elderly patients and its influence on inflammation.

METHODS

Totally 103 elderly patients with GC treated in our hospital between January 2020 and January 2022 were retrospectively analyzed. Among them, 45 patients treated with surgery based on deep NMB and conventional pneumoperitoneum pressure were assigned to the control group, while the rest of the 58 patients who underwent surgery based on deep NMB and reduced pneumoperitoneum pressure were assigned to the observation group. The two groups were compared in the changes of the Leiden-surgical rating scale score, serum tumor necrosis fact-α (TNF-α) and interleukin 6 (IL-6) before and after therapy. The visual analogue scale (VAS) was adopted for evaluating the shoulder pain of patients at 8 h, 24 h and 48 h after the operation. The driving pressure of the two groups at different time points was also compared. Additionally, the operation time, pneumoperitoneum time, infusion volume, blood loss, extubation time after surgery, residence time in the resuscitation room, TOF% = 90% time and post-anesthetic recovery room (PACU) stay time were all recorded, and adverse PACU-associated respiratory events were also recorded. The postoperative hospitalization time and postoperative expenses of the two groups were counted and compared.

RESULTS

No significant difference was found between the two groups at the time of skin incision, 60 minutes since the operation and abdominal closure after surgery (P > 0.05). The observation group exhibited significantly lower VAS scores than the control group at 24 and 48h after surgery (P < 0.05). Additionally, the observation group had significantly lower driving pressure than the control group at 5 min and 60 min after the establishment of pneumoperitoneum (P < 0.05). Additionally, the two groups were similar in terms of the operation time, pneumoperitoneum time, infusion volume, blood loss, extubation time after surgery, residence time in the resuscitation room and TOF% = 90% time (P > 0.05), and the observation group showed significantly lower TNF-α and IL-6 Levels than the control group at 24 h after therapy (P < 0.05). Moreover, the incidence of adverse events was not significantly different between the two groups (P > 0.05), and the observation group experienced significantly less hospitalization time and postoperative expenses than the control group (P < 0.05).

CONCLUSION

Deep NMB combined with reduced pneumoperitoneum pressure can decrease the VAS score of shoulder pain and inflammatory reaction, without hindering the surgical vision and increasing adverse PACU-associated respiratory events, and can thus shorten the hospitalization time and treatment cost for patient.

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.

Application of a highly simulated and adaptable training system in the laparoscopic training course for surgical residents: Experience from a high-volume teaching hospital in China

Objective

To explore the effectiveness, feasibility, and training effect of a highly simulated and adaptable laparoscopic training system in the advanced integrated two-stage laparoscopic simulation training course for surgical residents.

Methods

This study prospectively took the surgical residents who received the advanced integrated two-stage laparoscopic simulation training course in our hospital from December 2019 to December 2021 as the research objects. In the stage one course, the trainees are randomly distributed into the dry simulation system group and Darwin laparoscopic training system group. The subjective assessment results of the trainees from the two groups are collected by questionnaires, and the simulation assessment results of the two groups are evaluated in a unified, objective, and standardized assessment form. The pre-course and post-course questionnaires were used to evaluate the feasibility and effectiveness of the Darwin system in the stage two course.

Results

A total of 62 trainees completed the stage one and stage two courses. In the stage one course, the trainees were randomly distributed into the dry simulation trainer group (N = 19) and the Darwin group (N = 43). The results of the subjective assessment questionnaire showed that compared with the dry simulator group, the students in the Darwin group had higher subjective scores (P < 0.05). The objective assessment results for the 3 modules of "One Track Transfer", "One Tunnel Pass" and "High and Low Pillars" in the Darwin group were significantly better than those in the dry simulator group (P < 0.05). The trainees who received the stage two course completed the questionnaires before and after the course. The results showed that compared with pre-course evaluation, "basic theoretical knowledge of laparoscopy", "basic skills of laparoscopy", "laparoscopic suture technique" and "camera-holding technique" were significantly improved after training (P < 0.05).

Conclusion

The highly simulated and adaptable laparoscopic training system is effective and feasible in the advanced integrated two-stage laparoscopic simulation training course for surgical residents.

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.

Predictors of Clinical Outcomes Following Laparoscopic Colectomy for Traumatic Injury

BACKGROUND

Laparoscopic colectomy following traumatic injury has been increasingly utilized, but open resection remains the standard of care. Therefore, identifying appropriate candidates for laparoscopy is critically important. This study's purpose was to identify predictors of clinical outcomes in patients undergoing laparoscopic colectomy following traumatic injury.

METHODS

The National Trauma Databank was queried for patients undergoing laparoscopic colectomy within 48 hours of admission between 2007 and 2015. Patient, injury, and management characteristics were abstracted. Multivariable regression analyses adjusted for baseline characteristics and identified significant predictors of clinical outcomes.

RESULTS

A total of 581 patients satisfied inclusion criteria. The median age was 31 years, 465 (80%) were male, and 321 (55%) sustained penetrating injuries. An ostomy was created in 143 (25%) cases. Multivariable logistic regression showed that significant predictors of mortality included a falling mechanism (odds ratio [OR] 104.917, P = .002), admission tachycardia (OR 5.823, P = .001), admission hypotension (OR 26.089, P < .001), and multi-system injuries like head (OR 1.587, P = .008) and thoracic (OR 1.627, P = .001) injuries. Significant predictors of unplanned reoperation included transverse (OR 7.657, P = .033) and left (OR 17.155, P = .014) colon resections, obesity (OR 24.407, P = .016), and chronic respiratory disease (OR 32.963, P = .018). Ostomy creation was significantly associated with neither mortality nor unplanned reoperation.

CONCLUSION

These data suggest that readily identifiable preoperative characteristics are significantly associated with differences in clinical outcomes. Additional research is required to determine if varying treatment based on these qualities can improve outcomes.

Efficacy and Safety of Laparoscopy for Mild and Moderate Pediatric Abdominal Trauma: A Systematic Review and Meta-Analysis

In this systematic review and meta-analysis, we aimed to investigate the efficacy and safety of laparoscopy for pediatric patients with abdominal trauma. Relevant articles were obtained by searching the MEDLINE PubMed, EMBASE, and Cochrane databases until 7 December 2021. Meta-analyses were performed using odds ratio (OR) for binary outcomes, standardized mean differences (SMDs) for continuous outcome measures, and overall proportion for single proportional outcomes. Nine studies examining 12,492 patients were included in our meta-analysis. Our meta-analysis showed younger age (SMD −0.47, 95% confidence interval (CI) −0.52 to −0.42), lower injury severity score (SMD −0.62, 95% CI −0.67 to −0.57), shorter hospital stay (SMD −0.55, 95% CI −0.60 to −0.50), less complications (OR 0.375, 95% CI 0.309 to 0.455), and lower mortality rate (OR 0.055, 95% CI 0.0.28 to 0.109) in the laparoscopy group compared to the laparotomy group. The majority of patients were able to avoid laparotomy (0.816, 95% CI 0.800 to 0.833). There were no missed injuries during the laparoscopic procedures in seven eligible studies. Laparoscopy for stable pediatric patients showed favorable outcomes in terms of morbidity and mortality. There were no missed injuries, and laparotomy could be avoided for the majority of patients.

Open versus laparoscopic repair of traumatic diaphragmatic injury: A nationwide propensity-matched analysis

INTRODUCTION

Minimally invasive surgical techniques have become routinely applied in the evaluation and treatment of patients with isolated traumatic diaphragmatic injuries (TDI). However, there remains a paucity of data that compares the laparoscopic repair to the open repair approach. The aim of our study is to examine patient outcomes between TDI patients managed laparoscopically versus those managed using open repair.

METHODS

Adult (age ≥18 years) trauma patients presenting with TDI that required surgical repair were identified in the Trauma Quality Improvement Program database 2017. Patients were excluded if they underwent any other surgical procedure of the abdomen or chest. Patients were then stratified into 2 groups based on the surgical approach: laparoscopic repair of the diaphragm versus open repair. Propensity-score matching in a 1:2 ratio was performed. Primary outcome measures were in-hospital major complications and length of stay (LOS). Secondary outcome measure was in-hospital mortality.

RESULTS

A total of 177 adult trauma patients who had a laparoscopic repair of their isolated diaphragmatic injury were matched to 354 patients who had an open repair. Mean age was 35 ± 16 years, 78% were male, and mean BMI was 27 ± 7 kg/m². 67 percent of the patients had penetrating injuries, and the median ISS was 17 [9-21]. CT imaging was done in 67% of the patients, with 71% presenting with left-sided injury and 21% having visceral herniation. Conversion from laparoscopic to open was reported in 7.3% of the cases. Patients with a laparoscopic repair had significantly lower rates of major complications (5.6 versus 14.4%; P<0.001), shorter hospital LOS (6 [3-9] versus 9 [5-13] days; P<0.001) and ICU LOS (3 [2-7] versus 5 [2-10] days; P<0.001). No difference was found in rates of in-hospital mortality (0.6 versuss 2.0%; P = 0.129) between the 2 groups.

CONCLUSION

Laparoscopic repair of traumatic diaphragmatic injury was associated with decreased morbidity and a shorter hospital course, with a low conversion rate to open repair. Future studies remain necessary to further explore the long-term outcomes of patients with such injury.

Impact of laparoscopy on the perioperative outcome of penetrating abdominal trauma management during the post revolution period

BACKGROUND

Penetrating abdominal trauma (PAT) poses a significant challenge to trauma surgeons. Laparotomy is still the most popular procedure for managing PAT but has high morbidity and mortality rates. Presently, laparoscopy aims to provide equal or superior visualization compared to open approaches but with less morbidity, postoperative discomfort, and recovery time. The aim of this research is to assess the impact of laparoscopy on the management of PAT.

METHODS

This was a retrospective observational study carried out at the Emergency Hospital of Mansoura University/Egypt and at King Faisal Medical Complex, Taif/KSA from September 2014 to September 2018. All hemodynamically stable patients with PAT who were managed by laparoscopy were included in this study. Data extracted for analysis included demographic information, criteria of abdominal stabs, type of management, and perioperative outcome.

RESULTS

Forty patients were recruited in this research and the male-to-female ratio was 5.6:1. The mean age of the patients was 31.4 ± 12.318 years. During the laparoscopic procedure, no peritoneal penetration was observed in 4 patients (negative laparoscopy), while peritoneal penetration was observed in the remaining 36 patients. No visceral injuries were noted in 2 patients of the 36 patients with peritoneal penetration, while the remaining 34 patients had intra-abdominal injuries.

CONCLUSION

Laparoscopy performed on hemodynamically stable trauma patients was found to be safe and technically feasible. It also reduced negative and non-therapeutic laparotomies and offered paramount therapeutic and diagnostic advantages for traumatic diaphragmatic injuries.

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.

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.

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.

New insights in diagnostic laparoscopy

The basic concept of Diagnostic Laparoscopy (DL) is old but not old-fashioned. – Before the rise of tomography and ultrasound there was just the direct look into the abdomen and onto the affected organ available. As open surgery comes along with trauma, blood loss and infection, every effort have been made to improve the access strategies. Finally, due to innovation in optics, video technology and computer science, the look into the abdomen through a “keyhole” is a standard procedure today. – In this review we give an overview of history, implications and cost-effectiveness of DL, attempting an extrapolation of its future role.

Injury Characteristics and Outcomes of Patients With Inflammatory Bowel Disease After Trauma: A Propensity Score Matched Analysis

BACKGROUND

The clinical course of patients with inflammatory bowel disease (IBD) after trauma is largely unknown. We sought to compare the clinical course of patients with IBD to those without.

METHODS

We conducted a retrospective case-control study of adult patients admitted to a level-1 trauma center from January 1, 2008, through October 1, 2015. Seventy-five patients with IBD were identified. Cases were matched to controls by age, sex, injury severity, and mechanism using 4:1 propensity score-matching analysis. Injury characteristics, clinical course, and infectious and noninfectious complications were compared using bivariate and multivariate analysis.

RESULTS

Participants had a mean age of 56 years and mean injury severity score of 15. Of the 75 cases, 44% had ulcerative colitis, 44% had Crohn's disease, and 12% had undetermined type. More cases were on an immunosuppressant (19% vs 2%, P < 0.01) or steroids (8% vs 2%, P = 0.02) on admission compared with controls. More cases had prior abdominal surgery (P = 0.01). Cases had fewer brain injuries (P = 0.02) and higher admission Glasgow Coma Scale (P < 0.01) but required more neurosurgical intervention (P = 0.03). Cases required more orthopedic surgeries (P < 0.01) and more pain management consultations (P = 0.04). In multivariable analysis, IBD was associated with increased odds of operative intervention, pain management consultation, venous thromboembolism, and longer hospital stay (P < 0.05). Patients on immunosuppressants had increased odds of requiring surgery (P = 0.04), particularly orthopedic surgery (P < 0.01).

CONCLUSIONS

Baseline factors associated with inflammatory bowel disease may place patients at higher risk for surgery and complications after trauma.

Blunt Isolated Small Bowel Perforation Intervention: Does a Delay in Management Matter?

Purpose

Blunt small bowel injury is rare, and its timely diagnosis may be difficult. The effects of a delayed intervention on prognosis are unclear. We aimed to determine whether the time to surgical intervention affects outcomes in patients with blunt small bowel perforation.

Methods

The study was performed between March 2010 and December 2018 in adults (age >18 years) who initially underwent computed tomography and small bowel surgery only and survived more than one day postoperatively. They were categorized into three groups based on injury-to-surgery time intervals: ≤8, 8-24, and >24 h; similarly, they were also categorized into two groups of ≤24 and >24 h.

Results

Bowel resection, length of stay (LOS), intensive care unit (ICU) LOS, morbidity, and mortality were analyzed as outcomes in 52 patients. The number of patients in the three groups (≤8, 8-24, and >24 h) based on the time-to-surgery was 33, 13, and 6, respectively. On comparing the three groups, there were no significant differences in LOS (24 [18-35], 21 [10-40], and 28 [20-98] days, respectively; p=0.321), ICU LOS (2 [1-12], 4 [2-26], and 11 [7-14] days; respectively, p=0.153), mortality (3% (n = 1), 15% (n = 2), and 0%, respectively; p=0.291), and morbidity (46% (n = 15), 39% (n = 5), and 50% (n = 3), respectively; p=0.871). However, there was a significant difference between the groups in bowel resection (67% (n = 22), 31% (n = 4), and 83% (n = 5), respectively; p=0.037). Additionally, there was no significant difference in outcomes between the two groups (≤24 and >24 h) with small bowel perforation.

Conclusions

Delay in surgical intervention following blunt abdominal trauma may not affect the outcomes of patients with small bowel injuries, such as LOS, ICU LOS, morbidity, and mortality, except bowel resection.

Intersigmoid Hernia: A Forgotten Diagnosis-A Systematic Review of the Literature over Anatomical, Diagnostic, Surgical, and Medicolegal Aspects

Introduction

Intersigmoid hernia is a hernia of the small bowel into the intersigmoid fossa. It is well known to be a rare condition. Recent reports reveal that the preoperative differentiation of intersigmoid hernias is difficult and the diagnosis is often confirmed during the laparotomic exploration. Due to the vague clinical manifestation in most cases, the surgical treatment is frequently delayed.

Materials and Methods

In this study, we systematically reviewed the literature up to 2019 covering 114 studies and 124 patients with an intersigmoid hernia. The purpose of this work is to improve the understanding of the anatomical aspects, clinical presentation, diagnosis, and treatment of intersigmoid hernia so as to assist the preoperative differentiation of these hernias when presented as acute abdomen in the emergency department.

Results

The diameter of the intersigmoid recess was reported with mean 2.65 cm (range 1-10 cm, SD 1.15 cm) and the length of the incarcerated small intestine was between 3 cm (min) and 150 cm (max): mean 25.25 cm, SD 35.04 cm. The diameter of the sigmoid recess was greater in patients who underwent resection due to strangulation (mean 3.31 cm, SD 1.53 cm) compared to those who underwent only reduction of the hernia (mean 2.35 cm, SD 0.74 cm). The time from onset to operation was less in patients undergoing resection surgery due to throttling (mean 3.03 days, SD 3.01 days) compared to those who underwent only a reduction of hernia incarceration (mean 8.49 days, SD 6.83 days).

Conclusion

Intersigmoid hernia is often a forgotten diagnosis and a clinical challange due to its anatomical characteristics.

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.

"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.

Laparoscopic splenectomy with selective intra-corporeal ligation of splenic hilar vessels for high grade splenic injury - video vignette

A 59-year-old hemodynamically stable female is admitted following a domestic fall with blunt left sided thoraco-abdominal trauma. She lived alone and had multiple comorbidities including hepatitis C virus positive splenomegaly, chronic psychosis with a history of opioid and alcohol abuse. A CT-scan of thorax and abdomen with IV contrast showed left lung contusions and multiple left rib fractures with no pneumothorax, a high grade splenic injury with intra-parenchymal hematoma and small arterial blushes in the superior splenic pole associated with celiac trunk stenosis, mild intra-abdominal free fluid and grade II injury to the left kidney.
