RESUMO

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a grading system for emergency general surgery (EGS) conditions. We sought to validate the AAST EGS grades for patients undergoing urgent/emergent colorectal resection. METHODS: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included. Baseline demographics, comorbidity severity as defined by Charlson comorbidity index (CCI), procedure type, and AAST grade were prospectively collected. Outcomes included length of stay (LOS) in-hospital mortality, and surgical complications (superficial/deep/organ-space surgical site infection, anastomotic leak, stoma complication, fascial dehiscence, and need for further intervention). Multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication or mortality. RESULTS: There were 367 patients, with a mean (± SD) age of 62 ± 15 years. 39% were women. The median interquartile range (IQR) CCI was 4 (2-6). Overall, the pathologies encompassed the following AAST EGS grades: I (17, 5%), II (54, 15%), III (115, 31%), IV (95, 26%), and V (86, 23%). Management included laparoscopic (24, 7%), open (319, 87%), and laparoscopy converted to laparotomy (24, 6%). Higher AAST grade was associated with laparotomy (P = .01). The median LOS was 13 days (8-22). At least 1 surgical complication occurred in 33% of patients and the mortality rate was 14%. Development of at least 1 surgical complication, need for unplanned intervention, mortality, and increased LOS were associated with increasing AAST severity grade. On multivariable analysis, factors predictive of in-hospital mortality included AAST organ grade, CCI, and preoperative vasopressor use (odds ratio (OR) 1.9, 1.6, 3.1, respectively). The American Association for the Surgery of Trauma emergency general surgery grade was also associated with the development of at least 1 surgical complication (OR 2.5), while CCI, preoperative vasopressor use, respiratory failure, and pneumoperitoneum were not. CONCLUSION: The American Association for the Surgery of Trauma emergency general surgery grading systems display construct validity for mortality and surgical complications after urgent/emergent colorectal resection. These results support incorporation of AAST EGS grades for quality benchmarking and surgical outcomes research.

RESUMO

BACKGROUND: Viscoelastic tests including thromboelastography (TEG) and rotational thromboelastometry (ROTEM) are being used in patients with severe hemorrhage at trauma centers to guide resuscitation. Several recent studies demonstrated hypercoagulability in female trauma patients that was associated with a survival advantage. The objective of our study was to elucidate the effects of gender differences in TEG/ROTEM values on survival in trauma patients with severe hemorrhage. METHODS: A retrospective review of consecutive adult patients receiving massive transfusion protocol (MTP) at 7 Level I trauma centers was performed from 2013 to 2018. Data were stratified by gender and then further examined by TEG or ROTEM parameters. Results were analyzed using univariate and multi-variate analyses. RESULTS: A total of 1565 patients were included with 70.9% male gender (n = 1110/1565). Female trauma patients were older than male patients (43.5 ± .9 vs 41.1 ± .6 years, P = .01). On TEG, females had longer reaction times (6.1 ± .9 min vs 4.8 ± .2 min, P = .03), increased alpha angle (68.6 ± .8 vs 65.7 ± .4, P < .001), and higher maximum amplitude (59.8 ± .8 vs 56.3 ± .4, P < .001). On ROTEM, females had significantly longer clot time (99.2 ± 13.7 vs 75.1 ± 2.6 sec, P = .09) and clot formation time (153.6 ± 10.6 sec vs 106.9 ± 3.8 sec, P < .001). When comparing by gender, no difference for in-hospital mortality was found for patients in the TEG or ROTEM group (P > .05). Multivariate analysis showed no survival difference for female patients (OR 1.11, 95% CI .83-1.50, P = .48). CONCLUSIONS: Although a difference between male and females was found on TEG/ROTEM for certain clotting parameters, no difference in mortality was observed. Prospective multi-institutional studies are needed.

RESUMO

BACKGROUND: In the United States, the third leading cause of a large bowel obstruction (LBO) is colonic volvulus with torsion occurring most commonly in the sigmoid and the cecum. Transverse colonic volvulus (TCV) is exceedingly rare and specific involvement of the splenic flexure (SFV) is even less common. The present analysis was undertaken to interrogate current trends in presentation, management, and outcomes of TCV. METHODS: In the present report, the world literature was reviewed for the past 90 years (1932 to 2021). We conducted a systematic review to identify all cases of TCV following the PRISMA guidelines. RESULTS: We identified 317 cases of TCV. This included SFV (n = 75), TCV in pediatric patients (n = 63), TCV in pregnant patients (n = 8), and TCV associated with other pathology such as Chilaiditi's syndrome (n = 11). Compared to sigmoid and cecal volvulus, TCV was rare (.94%). It affected slightly more women (54%) than men, commonly in their third decade of life (37.7 ± 23.8). The clinical presentation and diagnostic imaging were consistent with LBO. Compared to sigmoid volvulus, there was a limited role for conservative management and colonoscopic decompression was less effective. The most common operation was segmental resection (25%). Mortality was (20%) commonly because of cardiopulmonary complications and affected more women (63%). The average age of this cohort was 55.7±24.6 years old. DISCUSSION: Our review showed that TCV is an uncommon surgical entity. The diagnosis is likely to be made at laparotomy. Prompt recognition is paramount in preventing ischemia necrosis and perforation. Compared to sigmoid and cecal volvulus, the mortality for TCV remains high.

RESUMO

In the USA, the third leading cause of a large bowel obstruction in adults is volvulus with torsion occurring commonly in the sigmoid and the cecum. Transverse colonic volvulus is exceedingly rare and specific involvement of the splenic flexure is even more uncommon. In the present report, we discuss a Veteran octogenarian who presented with a long-standing history of constipation, but then developed an acute abdomen from a large bowel obstruction. At laparotomy, he had a double closed loop obstruction with volvulus of the splenic flexure. The colon at the splenic flexure was ischemic with patchy areas of necrosis, but no perforation. He underwent a subtotal colectomy with an ileostomy. This case illustrates the need for prompt intervention of this unusual entity. Current trends in the incidence, management, morbidity and mortality are discussed.

RESUMO

OBJECTIVE: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection. Twenty-one centers enrolled patients for 11 months. Preoperative, intraoperative, and postoperative variables were recorded. χ, Mann-Whitney U test, and multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication/mortality. RESULTS: A total of 439 patients were enrolled (ANST, 184; STM, 255). The median (interquartile range) age was 62 (53-71) years, and the median Charlson Comorbidity Index (CCI) was 4 (1-6). The most common indication for surgery was diverticulitis (28%). Stoma group was older (64 vs. 58 years, p < 0.001), had a higher CCI, and were more likely to be immunosuppressed. Preoperatively, STM patients were more likely to be intubated (57 vs. 15, p < 0.001), on vasopressors (61 vs. 13, p < 0.001), have pneumoperitoneum (131 vs. 41, p < 0.001) or fecal contamination (114 vs. 33, p < 0.001), and had a higher incidence of elevated lactate (149 vs. 67, p < 0.001). Overall mortality was 13%, which was higher in STM patients (18% vs. 8%, p = 0.02). Surgical complications were more common in STM patients (35% vs. 25%, p = 0.02). On multivariable analysis, management with an open abdomen, intraoperative blood transfusion, and larger hospital size were associated with development of a surgical complication, while CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion were independently associated with mortality. CONCLUSION: This study highlights a tendency to perform fecal diversion in patients who are acutely ill at presentation. There is a higher morbidity and mortality rate in STM patients. Independent predictors of mortality include CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion. Following adjustment by clinical factors, method of colon management was not associated with surgical complications or mortality. LEVEL OF EVIDENCE: Therapeutic study, level IV.

RESUMO

BACKGROUND: Trauma centers are receiving increasing numbers of older trauma patients. There is a lack of literature on the outcomes for elderly trauma patients who undergo damage control laparotomy (DCL). We hypothesized that trauma centers with geriatric protocols would have better outcomes in elderly patients after DCL. METHODS: A retrospective chart review of consecutive adult trauma patients with DCL at 8 level 1 trauma centers was conducted from 2012 to 2018. Patients aged 40 or older were included. Age ≥ 55 years was defined as elderly. Demographics, injury information, clinical outcomes, including mortality, and complications were recorded. Univariate and multivariate analyses were performed. RESULTS: A total of 379 patients with DCLs were identified with an average age of 54.8 ± 0.4 years with 39.3% (n = 149/379) of patients aged ≥ 55. Geriatric protocols or a consulting geriatric service was present at 37.5% (n = 3/8) of institutions. Age ≥ 55 was a significant risk factor for in-hospital mortality (OR 2, 95% CI 1.0-4.0, P = .04). Institutions without dedicated geriatric trauma protocols/services had higher overall in-hospital mortality on both univariate (57.9% vs 34.3%, P = .02) and multivariate analyses (OR 2.1, 95% CI 1.3-3.4, P < .001). CONCLUSIONS: Surgical management of older trauma patients remains a challenge. Geriatric protocols or dedicated services were found to be associated with improved outcomes. Future efforts should focus on standardizing the availability of these resources at trauma centers.

RESUMO

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are life-threatening surgical emergencies associated with high morbidity and mortality. Fungal NSTIs are considered rare and have been largely understudied. The purpose of this study was to study the impact of fungal NSTIs and antifungal therapy on mortality after NSTIs. METHODS: A retrospective chart review was performed on patients with NSTIs from 2012 to 2018. Patient baseline characteristics, microbiologic data, antimicrobial therapy, and clinical outcomes were collected. Patients were excluded if they had comfort care before excision. The primary outcome measured was in-hospital mortality. RESULTS: A total of 215 patients met study criteria with a fungal species identified in 29 patients (13.5%). The most prevalent fungal organism was Candida tropicalis (n = 11). Fungal NSTIs were more prevalent in patients taking immunosuppressive medications (17.2% versus 3.2%, P = 0.01). A fungal NSTI was significantly associated with in-hospital mortality (odds ratio, 3.13; 95% confidence interval, 1.16-8.40; P = 0.02). Furthermore, fungal NSTI patients had longer lengths of stay (32 d [interquartile range, 16-53] versus 19 d [interquartile range, 11-31], P < 0.01), more likely to require initiation of renal replacement therapy (24.1% versus 8.6%, P = 0.02), and more likely to require mechanical ventilation (64.5% versus 42.0%, P = 0.02). Initiation of antifungals was associated with a significantly lower rate of in-hospital mortality (6.7% versus 57.1%, P = 0.01). CONCLUSIONS: Fungal NSTIs are more common in patients taking immunosuppressive medications and are significantly associated with in-hospital mortality. Antifungal therapy is associated with decreased in-hospital mortality in those with fungal NSTIs. Consideration should be given to adding antifungals in empiric treatment regimens, especially in those taking immunosuppressive medications.

RESUMO

OBJECTIVE: This study aimed to determine the emotional intelligence (EI) of surgical faculty and evaluate its relationship with resident evaluations of faculty behaviors. DESIGN: This study retrospectively collected faculty EI scores as well as general surgery resident evaluations of faculty. Parametric and nonparametric tests were used for statistical analysis. SETTING: The study was conducted at the University of Texas Southwestern in the Department of Surgery in Dallas, Texas. This is an academic, tertiary care center. PARTICIPANTS: Surgical faculty members at a single institution in 2018 completed the Emotional Intelligence Appraisal, a 28-item, electronic assessment with possible scores ranging from zero to 100. Aggregate, anonymous resident evaluations of faculty members were collected from the program director's office. Faculty with fewer than 8 resident evaluations were excluded. RESULTS: In total, 59 faculty members participated (89%). The sample was mostly white (69.2%), male (63.5%), with an average of 47 ± 10 years of age, 12.2 ± 10 years in practice, and 44 ± 24 evaluations per faculty member. The group's mean EI score was 76 ± 7.7. Faculty EI scores were found to have a moderate, positive correlation with resident rotational evaluations of faculty (r(51) = 0.52, p < 0.001). Faculty EI scores did not significantly correlate with resident evaluations of faculty intraoperative behaviors. CONCLUSIONS: The results of this study suggest that a majority of our faculty are competent with regard to EI. Furthermore, faculty EI is an important factor in the clinical learning environment and correlates with resident rotational evaluations of teaching behaviors.

RESUMO

BACKGROUND: Outcomes of appendectomy stratified by type of complicated appendicitis (CA) features are poorly researched, and the evidence to guide operative versus nonoperative management for CA is lacking. This study aimed to determine laparoscopic-to-open conversion risk, postoperative abscess risk, unplanned readmission risk, and length of hospital stay (LOS) associated with appendectomy in patients with perforated appendicitis without abscess (PA) and perforated appendicitis with abscess (PAWA) compared with a control cohort of nonperforated appendicitis (NPA). METHODS: The 2016-2017 National Surgical Quality Improvement Program Appendectomy-targeted database identified 12,537 (76.1%) patients with NPA, 2142 (13.0%) patients with PA, and 1799 (10.9%) patients with PAWA. Chi-squared analysis and analysis of variance were used to compare categorical and continuous variables. Binary logistic and linear regression models were used to compare risk-adjusted outcomes. RESULTS: Compared with NPA, PA and PAWA had higher rates of conversion (0.8% versus 4.9% and 6.5%, respectively; P < 0.001), postoperative abscess requiring intervention (0.6% versus 4.8% and 7.0%, respectively; P < 0.001), readmission (2.8% versus 7.7% and 7.6%, respectively; P < 0.001), and longer median LOS (1 day versus 2 days and 2 days, respectively; P < 0.001). PA and PAWA were associated with increased odds of postoperative abscess (odds ratio [OR]: 7.18, 95% confidence interval [CI]: 5.2-9.8 and OR: 9.94, 95% CI: 7.3-13.5, respectively), readmission (OR: 2.70, 95% CI: 2.1-3.3 and OR: 2.66, 95% CI: 2.2-3.3, respectively), and conversion (OR: 5.51, 95% CI: 4.0-7.5 and OR: 7.43, 95% CI: 5.5-10.1, respectively). PA was associated with an increased LOS of 1.7 days and PAWA with 1.9 days of LOS (95% CI: 1.5-1.8 and 1.7-2.1, respectively). CONCLUSIONS: Individual features of CA were independently associated with outcomes. Further research is needed to determine if surgical management is superior to nonoperative management for CA.

RESUMO

BACKGROUND: While the prevalence of HIV infection in the population is 0.5%, it is higher among trauma patients as are rates of unknown seropositivity. Routine HIV screening for all trauma evaluations was implemented at our urban level I center in 2009. We aimed to evaluate use and results of the program in our trauma population. METHODS: This was a retrospective analysis of all trauma evaluations between July 2015 and February 2018. After passage of legislation rescinding the requirement for consent to perform HIV testing, our trauma service instituted an order set which automatically tested for HIV unless the ordering physician opted out. Patients found to be infected with HIV were to be counseled and referred to specialty care. RESULTS: Of 6175 consecutive trauma evaluations during the study period, 449 (7.3%) patients had been screened within the prior year and were excluded. Of the remaining cohort, 2024 (35.3%) patients were screened with 27 (1.3%) testing positive. Among those testing positive for infection, 100% were male, 77% white, 63% non-Hispanic, and 70% lacked insurance. Twenty-five (92.6%) patients received counseling and 19 were referred to specialty care. Age, gender, race, ethnicity, Injury Severity Score, trauma activation level, and payor type were not significant predictors for positive HIV screen on logistic regression analysis. CONCLUSIONS: Despite a significantly higher rate of HIV in the trauma population, only a third of patients are screened. Such high infection rates justify the existence of this screening program but steps must be taken to increase screening rate. LEVEL OF EVIDENCE: Level 3.

RESUMO

Background: Necrotizing soft tissue infections (NSTI) are a surgical emergency with significant morbidity and mortality rates. It has been thought that NSTIs are best treated in large tertiary centers. However, the effect of transfer has been under-studied. We examined whether transfer status is associated with a higher mortality rate in NSTIs. Methods: We conducted a retrospective review of patients with an International Classification of Disease (ICD) code associated with NSTI seen from 2012-2015 at two tertiary care institutions. Patients transferred to a tertiary center (T-NSTI) were compared with those who were treated initially at a tertiary center (P-NSTI). The primary endpoint was in-hospital death. Results: A total of 138 patients with NSTI met our study criteria, 39 transfer patients (28.0%) and 99 (72.0%) who were treated primarily at our institutions. The mortality rate was significantly higher for T-NSTI patients than P-NSTI patients (35.9% versus 14.1%; p < 0.01) with an adjusted odds ratio of 5.33 (95% confidence interval 1.02-28.30; p = 0.04). The need for hemodialysis was an independent predictor of in-hospital death. Treatment at a Level 1 trauma center and current smoking status were independent protectors???? of in-hospital death. For the transfer patients, the timing of transfer and debridement status were not different in survivors and non-survivors. However, there was a trend toward a lower in-hospital mortality rate if patients were transferred early without prior debridement than in all other transfers (21.4% versus 40.0%; p = 0.21). The in-hospital mortality rate was significantly lower at the Level 1 trauma center than at the non-trauma tertiary center (15.5% versus 34.3%; p = 0.02). Conclusion: Transfer status is an independent predictor of in-hospital death in patients with NSTI. Larger, multi-institutional studies are needed to elucidate further what factors contribute to the higher mortality rate in these patients.

RESUMO

The effects of injecting tumescence containing phenylephrine in pediatric burn patients are unknown, but anecdotally our clinicians note a high incidence of hypertension requiring treatment. This study sought to determine whether tumescence with phenylephrine was associated with hypertension requiring treatment in our pediatric burn patients. This was a retrospective cohort study of pediatric burn patients who underwent tangential excision with split-thickness autografting, excision alone, or autografting alone from 2013 to 2017. Records were reviewed for hypertensive episodes, defined as ≥2 consecutive blood pressure readings that were >2 SD above normal. Published intraoperative age- and sex-adjusted standards were used to define reference values. Parametric and nonparametric tests were used when appropriate. In total, 258 operations were evaluated. Mean patient age was 7.6 ± 5.2 years, and 64.7% were male. Patients were predominately white (69.8%). Overall, there was a 62.8% incidence of hypertension. On univariate logistic regression analysis, duration of operation, estimated blood loss, treated TBSA, and weight-adjusted volume of tumescence were significant predictors of intraoperative hypertension (P < .01). On multivariate analysis, weight-adjusted volume of tumescence alone was significantly associated with the presence of hypertension with an odds ratio of 2.0 (95% confidence interval: 1.33-3.04). Of the 162 operations which exhibited at least one episode of significant hypertension, 128 cases (79%) were treated. Intraoperative administration of phenylephrine-containing tumescence in pediatric burn patients is associated with clinically significant hypertension requiring treatment. This practice should be conducted with caution in pediatric burn operations until its clinical implications are defined.
