Combined Endoscopic Robotic Surgery for Complex Colon Polyps.

BACKGROUND: Combined endoscopic robotic surgery is a surgical technique that modifies traditional endoscopic laparoscopic surgery with robotic assistance to aid in the removal of complex colonic polyps. This technique has been described in the literature but lacks patient follow-up data. OBJECTIVE: This study aimed to evaluate the safety and outcomes of combined endoscopic robotic surgery. DESIGN: A retrospective review of a prospective database. SETTING: East Jefferson General Hospital, Metairie, Louisiana. PATIENTS: Ninety-three consecutive patients who underwent combined endoscopic robotic surgery from March 2018 to October 2021 were included in the study. MAIN OUTCOME MEASURES: Operative time, intraoperative complication, 30-day postoperative complication, hospital length of stay, and follow-up pathology report results were the main outcome measures. RESULTS: Combined endoscopic robotic surgery was completed in 88 of 93 participants (95%). Among the 88 participants who completed combined endoscopic robotic surgery, the average age was 66 years (SD = 10), BMI was 28.8 kg/m 2 (SD = 6), and history of previous abdominal surgeries was 1 (SD = 1). Median operative time was 72 minutes (range, 31-184 minutes) and polyp size was 40 mm (range, 5-180 mm). The most common polyp locations were the cecum, ascending colon, and transverse colon (31%, 28%, 25%). Pathology mainly demonstrated tubular adenoma (76%). Data on 40 patients who underwent follow-up colonoscopy were available. The average follow-up time was 7 months (range, 3-22 months). One patient (2.5%) had polyp recurrence at the resection site. LIMITATIONS: Limitations for our study include a lack of randomization and follow-up rate to assess for recurrence. The low compliance rate may be due to procedure cancelations/difficulty scheduling because of changing coronavirus disease 2019 guidelines. CONCLUSIONS: Compared to literature-reported statistics for its laparoscopic counterpart, combined endoscopic robotic surgery was associated with decreased operation times and resection site polyp recurrence.

Combined endoscopic robotic surgery for complex colonic polyp resection: case series.

BACKGROUND: The study objective was to evaluate combined endoscopic and robotic surgery, a novel surgical technique modifying traditional combined endoscopic laparoscopic surgery through robotic assistance, and characterize a series of patients who underwent the modified operative technique. METHODS: A retrospective case series was performed. The first thirty-seven consecutive patients who underwent combined endoscopic robotic surgery by a single colorectal surgeon from March 2018 to October 2019 were included. Main outcome measures included operative time, intra-operative complication, 30-day post-operative complication, and hospital length of stay. RESULTS: Combined endoscopic and robotic surgery was performed in 37 cases, 32 (86.5%) of which saw the technique through to completion. Median operative room time was 73 min (range 31-184 min). No intraoperative complications occurred and 2 (6.3%) experienced 30-day post-operative complications. Median hospital length of stay was 1.1 days (range 0.2-2.0 days). Median polyp size was 35 mm (range 20-130 mm). Polyps were resected from the following locations: cecum (37.5%), ascending colon (28.1%), transverse colon (21.9%), descending colon (3.1%), sigmoid colon (6.3%), and rectum (3.1%). Pathology demonstrated 77.4% tubular adenoma, 12.9% sessile serrated adenoma, 6.5% dysplasia, and 3.2% signet cell adenocarcinoma. CONCLUSION: Combined endoscopic robotic surgery was associated with decreased operative time, complication rates, and hospital length of stay compared to literature-reported statistics for combined endoscopic laparoscopic surgery. Increased confidence with 3-dimensional visualization and intracorporeal suturing using combined endoscopic and robotic surgery was noted. Additional studies are needed to further define the role of robotics in combined endoscopic surgery.

Resuscitative endovascular balloon occlusion of the aorta in the patient with obesity.

BACKGROUND: Palpation of anatomic landmarks is difficult in patients with obesity, which could increase difficulty of achieving femoral access and resuscitative endovascular balloon occlusion of the aorta (REBOA) placement. The primary aim of this study was to examine the association between obesity and successful REBOA placement. We hypothesized that higher body mass index (BMI) would decrease first-attempt success and increase time to successful aortic occlusion (AO). METHODS: A review of the Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery (AORTA) registry was performed on patients who underwent REBOA placement with initiation systolic blood pressure >0 mm Hg from years 2013-2022. Patients were excluded if they received cardiopulmonary resuscitation on arrival, underwent open AO, or missing data entries for variables of interest. Body mass index categorization was as follows: non-obese (<30), class I (30-34.9), class II (35-39.9), and class III (40+) obesity. Patients were also stratified by access technique, including use of palpation or ultrasound guidance. RESULTS: Inclusion criteria were met by 410 patients. On binary analysis, no primary outcomes of interest, including rate of success, time to placement, or mortality, were significantly impacted by BMI. Among BMI subgroups, there was no statistical difference in injury severity, admission systolic blood pressure (SBP), or augmented SBP. At initiation of aortic occlusion, patients with class II and class III obesity had higher median SBP compared with non- and class I obese patients (p = 0.03). Body mass index subgroup did not impact likelihood of first-attempt success or conversion to open procedure. When stratified by access technique, there was no difference in success rates, time to success or mortality between groups. CONCLUSION: Body habitus did not impact success of REBOA placement, time to successful AO, or mortality. Further, ultrasound guidance was not superior to landmark palpation for arterial access. Following traumatic injury without hemodynamic collapse, obesity should not deter providers from considering REBOA placement.

Every minute matters: Improving outcomes for penetrating trauma through prehospital advanced resuscitative care.

INTRODUCTION: Prehospital resuscitation with blood products is gaining popularity for patients with traumatic hemorrhage. The MEDEVAC trial demonstrated a survival benefit exclusively among patients who received blood or plasma within 15 minutes of air medical evacuation. In fast-paced urban EMS systems with a high incidence of penetrating trauma, mortality data based on the timing to first blood administration is scarce. We hypothesize a survival benefit in patients with severe hemorrhage when blood is administered within the first 15 minutes of EMS patient contact. METHODS: This was a retrospective analysis of a prospective database of prehospital blood (PHB) administration between 2021 and 2023 in an urban EMS system facing increasing rates of gun violence. PHB patients were compared to trauma registry controls from an era before prehospital blood utilization (2016-2019). Included were patients with penetrating injury and SBP ≤ 90 mmHg at initial EMS evaluation that received at least one unit of blood product after injury. Excluded were isolated head trauma or prehospital cardiac arrest. Time to initiation of blood administration before and after PHB implementation and in-hospital mortality were the primary variables of interest. RESULTS: A total of 143 patients (PHB = 61, controls = 82) were included for analysis. Median age was 34 years with no difference in demographics. Median scene and transport intervals were longer in the PHB cohort, with a 5-minute increase in total prehospital time. Time to administration of first unit of blood was significantly lower in the PHB vs. control group (8 min vs 27 min; p < 0.01). In-hospital mortality was lower in the PHB vs. control group (7% vs 29%; p < 0.01). When controlling for patient age, NISS, tachycardia on EMS evaluation, and total prehospital time interval, multivariate regression revealed an independent increase in mortality by 11% with each minute delay to blood administration following injury (OR 1.11, 95%CI 1.04-1.19). CONCLUSION: Compared to patients with penetrating trauma and hypotension who first received blood after hospital arrival, resuscitation with blood products was started 19 minutes earlier after initiation of a PHB program despite a 5-minute increase in prehospital time. A survival for early PHB use was demonstrated, with an 11% mortality increase for each minute delay to blood administration. Interventions such as PHB may improve patient outcomes by helping capture opportunities to improve trauma resuscitation closer to the point of injury. LEVEL OF EVIDENCE: Prospective, Level IV.

Faster refill in an urban emergency medical services system saves lives: A prospective preliminary evaluation of a prehospital advanced resuscitative care bundle.

INTRODUCTION: Military experience has demonstrated mortality improvement when advanced resuscitative care (ARC) is provided for trauma patients with severe hemorrhage. The benefits of ARC for trauma in civilian emergency medical services (EMS) systems with short transport intervals are still unknown. We hypothesized that ARC implementation in an urban EMS system would reduce in-hospital mortality. METHODS: This was a prospective analysis of ARC bundle administration between 2021 and 2023 in an urban EMS system with 70,000 annual responses. The ARC bundle consisted of calcium, tranexamic acid, and packed red blood cells via a rapid infuser. Advanced resuscitative care patients were compared with trauma registry controls from 2016 to 2019. Included were patients with a penetrating injury and systolic blood pressure ≤90 mm Hg. Excluded were isolated head trauma or prehospital cardiac arrest. In-hospital mortality was the primary outcome of interest. RESULTS: A total of 210 patients (ARC, 61; controls, 149) met the criteria. The median age was 32 years, with no difference in demographics, initial systolic blood pressure or heart rate recorded by EMS, or New Injury Severity Score between groups. At hospital arrival, ARC patients had lower median heart rate and shock index than controls ( p ≤ 0.03). Fewer patients in the ARC group required prehospital advanced airway placement ( p < 0.001). Twenty-four-hour and total in-hospital mortality were lower in the ARC group ( p ≤ 0.04). Multivariable regression revealed an independent reduction in in-hospital mortality with ARC (odds ratio, 0.19; 95% confidence interval, 0.05-0.68; p = 0.01). CONCLUSION: Early ARC in a fast-paced urban EMS system is achievable and may improve physiologic derangements while decreasing patient mortality. Advanced resuscitative care closer to the point of injury warrants consideration. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

BACKGROUND: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients. MATERIALS AND METHODS: This is a post-hoc analysis of a multicenter, prospective, observational study of adults (18+ years) with penetrating torso and/or proximal extremity injury presenting at 25 urban trauma centers. Tranexamic acid administration in the prehospital setting or within three hours of admission was examined. Participants were propensity matched to compare similarly injured patients. The primary outcome was development of pulmonary complication (ARDS and/or pneumonia). RESULTS: A total of 2382 patients were included, and 206 (8.6%) received TXA. Of the 206, 93 (45%) received TXA prehospital and 113 (55%) received it within three hours of hospital admission. Age, sex, and incidence of massive transfusion did not differ. The TXA group was more severely injured, more frequently presented in shock (SBP < 90 mmHg), developed more pulmonary complications, and had lower survival (P < 0.01 for all). After propensity matching, 410 patients remained (205 in each cohort) with no difference in age, sex, or rate of shock. On logistic regression, increased emergency department heart rate was associated with pulmonary complications. Tranexamic acid was not associated with different rate of pulmonary complications or survival on logistic regression. Survival was not different between the groups on logistic regression or propensity score-matched analysis. CONCLUSIONS: Tranexamic acid administration is not protective against pulmonary complications in penetrating trauma patients.

A CIRCULATION-FIRST APPROACH FOR RESUSCITATION OF TRAUMA PATIENTS WITH HEMORRHAGIC SHOCK.

ABSTRACT: The original guidelines of cardiopulmonary resuscitation focused on the establishment of an airway and rescue breathing before restoration of circulation through cardiopulmonary resuscitation. As a result, the airway-breathing-circulation approach became the central guiding principle of resuscitation. Despite new guidelines by the American Heart Association for a circulation-first approach, Advanced Trauma Life Support guidelines continue to advocate for the airway-breathing-circulation sequence. Although definitive airway management is often necessary for severely injured patients, endotracheal intubation (ETI) before resuscitation in patients with hemorrhagic shock may worsen hypotension and precipitate cardiac arrest. In severely injured patients, a paradigm shift should be considered, which prioritizes restoration of circulation before ETI and positive pressure ventilation while maintaining a focus on basic airway assessment and noninvasive airway interventions. For this patient population, the most reasonable current strategy may be to target a simultaneous resuscitation approach, with immediate efforts to control hemorrhage and provide basic airway interventions while prioritizing volume resuscitation with blood products and deferring ETI until adequate systemic perfusion has been attained. We believe that a circulation-first sequence will improve both survival and neurologic outcomes for a traumatically injured patient and will continue to advocate this approach, as additional clinical evidence is generated to inform how to best tailor circulation-first resuscitation for varied injury patterns and patient populations.

Cost-Effectiveness of Universal Screening for Blunt Cerebrovascular Injury: A Markov Analysis.

BACKGROUND: Blunt cerebrovascular injury (BCVI) is a significant cause of morbidity and mortality after blunt trauma. Numerous screening strategies exist, although which is used is institution- and physician-dependent. We sought to identify the most cost-effective screening strategy for BCVI, hypothesizing that universal screening would be optimal among the screening strategies studied. STUDY DESIGN: A Markov decision analysis model was used to compare the following screening strategies for identification of BCVI: (1) no screening; (2) Denver criteria; (3) extended Denver criteria; (4) Memphis criteria; and (5) universal screening. The base-case scenario modeled 50-year-old patients with blunt traumatic injury excluding isolated extremity injures. Patients with BCVI detected on imaging were assumed to be treated with antithrombotic therapy, subsequently decreasing risk of stroke and mortality. One-way sensitivity analyses were performed on key model inputs. A single-year horizon was used with an incremental cost-effectiveness ratio threshold of $100,000 per quality-adjusted life-year. RESULTS: The most cost-effective screening strategy for patients with blunt trauma among the strategies analyzed was universal screening. This method resulted in the lowest stroke rate, mortality, and cost, and highest quality-adjusted life-year. An estimated 3,506 strokes would be prevented annually as compared with extended Denver criteria (incremental cost-effectiveness ratio of $71,949 for universal screening vs incremental cost-effectiveness ratio of $12,736 for extended Denver criteria per quality-adjusted life-year gained) if universal screening were implemented in the US. In 1-way sensitivity analyses, universal screening was the optimal strategy when the incidence of BCVI was greater than 6%. CONCLUSIONS: This model suggests universal screening may be the cost-effective strategy for BCVI screening in blunt trauma for certain trauma centers. Trauma centers should develop institutional protocols that take into account individual BCVI rates.

IMPACT OF TIME TO EMERGENCY DEPARTMENT RESUSCITATIVE AORTIC OCCLUSION AFTER NONCOMPRESSIBLE TORSO HEMORRHAGE.

ABSTRACT: Introduction: Time is an essential element in outcomes of trauma patients. The relationship of time to treatment in management of noncompressible torso hemorrhage (NCTH) with resuscitative endovascular balloon occlusion of the aorta (REBOA) or resuscitative thoracotomy (RT) has not been previously described. We hypothesized that shorter times to intervention would reduce mortality. Methods: A review of the Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery registry from 2013 to 2022 was performed to identify patients who underwent emergency department aortic occlusion (AO). Multivariate logistic regression was used to examine the impact of time to treatment on mortality. Results: A total of 1,853 patients (1,245 [67%] RT, 608 [33%] REBOA) were included. Most patients were male (82%) with a median age of 34 years (interquartile range, 30). Median time from injury to admission and admission to successful AO were 31 versus 11 minutes, respectively. Patients who died had shorter median times from injury to successful AO (44 vs. 72 minutes, P < 0.001) and admission to successful AO (10 vs. 22 minutes, P < 0.001). Multivariate logistic regression demonstrated that receiving RT was the strongest predictor of mortality (odds ratio [OR], 6.6; 95% confidence interval [CI], 4.4-9.9; P < 0.001). Time from injury to admission and admission to successful AO were not significant. This finding was consistent in subgroup analysis of RT-only and REBOA-only populations. Conclusions: Despite expedited interventions, time to aortic occlusion did not significantly impact mortality. This may suggest that rapid in-hospital intervention was often insufficient to compensate for severe exsanguination and hypovolemia that had already occurred before emergency department presentation. Selective prehospital advanced resuscitative care closer to the point of injury with "scoop and control" efforts including hemostatic resuscitation warrants special consideration.
