Coronavirus disease 2019 (COVID-19) has been shown to affect outcomes among surgical patients. We hypothesized that COVID-19 would be linked to higher mortality and longer length of stay of trauma patients regardless of the injury severity score (ISS).We performed a retrospective analysis of trauma registries from two level 1 trauma centers (suburban and urban) from March 1, 2019, to June 30, 2019, and March 1, 2020, to June 30, 2020, comparing baseline characteristics and cumulative adverse events. Data collected included ISS, demographics, and comorbidities. The primary outcome was time from hospitalization to in-hospital death. Outcomes during the height of the first New York COVID-19 wave were also compared with the same time frame in the prior year. Kaplan-Meier method with log-rank test and Cox proportional hazard models were used to compare outcomes.There were 1180 trauma patients admitted during the study period from March 2020 to June 2020. Of these, 596 were never tested for COVID-19 and were excluded from the analysis. A total of 148 COVID+ patients and 436 COVID- patients composed the 2020 cohort for analysis. Compared with the 2019 cohort, the 2020 cohort was older with more associated comorbidities, more adverse events, but lower ISS. Higher rates of historical hypertension, diabetes, neurologic events, and coagulopathy were found among COVID+ patients compared with COVID- patients. D-dimer and ferritin were unreliable indicators of COVID-19 severity; however, C-reactive protein levels were higher in COVID+ relative to COVID- patients. Patients who were COVID+ had a lower median ISS compared with COVID- patients, and COVID+ patients had higher rates of mortality and longer length of stay.COVID+ trauma patients admitted to our two level 1 trauma centers had increased morbidity and mortality compared with admitted COVID- trauma patients despite age and lower ISS. C-reactive protein may play a role in monitoring COVID-19 activity in trauma patients. A better understanding of the physiological impact of COVID-19 on injured patients warrants further investigation.

Introduction This study was conducted to assess the diagnostic accuracy of three-dimensional computed tomography (3D-CT) in detection of cervical spine injuries in symptomatic post-trauma patients using multiplanar computed tomography (MP-CT) as reference standard. Approach This cross-sectional study was conducted at Aga Khan University from July 2016 to January 2017. Patients were included using a non-probability, consecutive sampling. MP-CT and 3D- CT images were obtained and evaluated by a senior radiologist to identify cervical spine injuries. Results 205 patients were included in the study. For fractures, 3D-CT images had sensitivity of 71%, specificity of 100%, positive predictive value (PPV) of 100%, negative predictive value (NPV) of 96.8% and diagnostic accuracy of 97%. For dislocations, 3D-CT reported sensitivity of 83.34%, specificity of 100%, positive predictive value of 100% and negative predictive value of 99.5% and diagnostic accuracy of 99.5%. Conclusion 3D-CT has good diagnostic accuracy for injuries of the cervical spine but must be reviewed simultaneously with multiplanar CT images.

Introduction Many patients admitted to hospitals with acute trauma have positive serum blood alcohol levels. Published associations between alcohol use, injury patterns, and outcomes are inconsistent. We sought to further delineate the impact of alcohol use and alcohol withdrawal on hospital outcomes amongst acute trauma patients. Methods We performed a retrospective analysis of adult trauma patients hospitalized at a suburban level 1 trauma center between January 2015 and September 2019 with a blood alcohol level measurement and/or classification as alcohol withdrawal syndrome (AWS). Patients were separated into three groups: BAL ≤10 mg/dL, BAL >10 mg/dL, and alcohol withdrawal syndrome (AWS). Results Overall, 3896 patients met study criteria with 75.6% BAL ≤10, 23.2% BAL >10, and 1.2% AWS. The median age was significantly different (BAL ≤ 10: 59 years, BAL > 10: 44 years, AWS: 53.5 years). Alcohol withdrawal was experienced by patients with BAL ≤10 and BAL >10. While injury severity and mortality were similar across all 3 groups, AWS patients experienced significantly longer hospital and ICU lengths of stay, unplanned ICU admission, need for mechanical ventilation, and higher rates of complications. Patients with AWS had high rates of acute neuropsychiatric symptoms, complicating their management. Conclusions Except for mortality, AWS patients experienced worse outcomes. The complex nature of alcohol withdrawal cases, including the possibility of developing AWS despite a negative BAL on admission, emphasizes the need for early assessment for alcohol withdrawal risk factors and input from specialists.

Despite the growth of minimally invasive surgery (MIS) in many specialties, open colon surgery is still routinely performed. The purpose of this study was to compare outcomes and costs between open colon and minimally invasive colon resections.We analyzed outcomes between January 1, 2016 and December31, 2018 using the Vizient® clinical database. Demographics, hospital length of stay, readmissions, complications, mortality, and costs were compared between patients undergoing elective open and minimally invasive colon resections. For bivariate analysis, Wilcoxon rank-sum test was used for continuous variables and χA total of 88,405 elective colon resections (open: 56,599; minimally invasive: 31,806) were reviewed. A significantly larger proportion of patients undergoing minimally invasive surgery were obese (body mass index30) compared to those undergoing open surgery (71.4% vs. 59.6%; p 0.0001). As compared to minimally invasive colectomy, open colectomy patients had: a longer median length of stay [median (range): 7 (4-13) days vs. 4 (3 - 6) days, p 0.0001], higher 30-day readmission rate [n = 8557 (15.1%) vs. 2815 (8.9%), p 0.0001], higher mortality [n = 2590 (4.4%) vs. 107 (0.34%), p 0.0001], and a higher total direct cost [median (range): $13,582 (9041-23,094) vs. $9013 (6748 - 12,649), p 0.0001]. Multivariable models confirmed these findings.Minimally invasive colon surgery has clear benefits in terms of length of stay, readmission rate, mortality and cost, and the routine use of open colon resection should be revaluated.

Background: Isosulfan blue dye, or Lymphazurin, is commonly used for sentinel lymph node biopsy during operative procedures for patients with breast cancer. Allergic reactions to Lymphazurin have been reported, ranging from mild dermatologic reactions to severe anaphylaxis. Case Series: We report 2 patients who experienced allergic reaction to Lymphazurin while admitted to our service. We also conducted a literature search for similar cases using national databases. Included studies were limited to retrospective studies, case series, or case reports. Patient characteristics, reaction observed, and hospital course were extracted. Of the patients we report, both had grade 3 anaphylactic reactions requiring vasopressors to achieve hemodynamic stability. One patient required intensive care unit monitoring for 18 hours, and the other required overnight monitoring in the postanesthesia care unit. The literature revealed 29 studies reporting 108 patients with confirmed allergic reactions to Lymphazurin. Including the 2 patients in this series (total study n=110), most reactions were grade 3 (57/110, 51.8%), followed by grade 1 (40/110, 36.4%) and grade 2 (13/110, 11.8%). Among the patients who had individual hospital course reported (n=34), 23 patients required admission to the surgical intensive care unit. Of studies that reported cancellation or progression of surgery after the reaction, the surgical procedure was canceled for 12 of 26 patients (46.1%). Conclusion: Although severe anaphylactic reactions are more commonly reported, mild reactions occur more frequently but are likely underreported. Although no fatalities were reported in the cases included in this review, anaphylactic reactions to Lymphazurin pose significant risks. Operating room personnel should be familiar with potential reactions to recognize and treat them early.

During the COVID pandemic, elective global surgical missions were temporarily halted for the safety of patients and travelling healthcare providers. We discuss our experience during our first surgical mission amidst the pandemic. We report a safe and successful treatment of the patients, detailing our precautionary steps and outcomes.Retrospective manual chart review and data collection of patients' charts was conducted after IRB approval. We entail our experience and safety steps followed during screening, operating and postoperative care to minimize exposure and improve outcomes during a surgical mission in an outpatient setting during the pandemic. The surgical mission was from February 8 to February 12, 2022.A total of 60 patients who were screened. 33 patients underwent surgical intervention. One patient required postoperative hospitalization for a biliary duct leak. No patient or healthcare provider tested positive for COVID at the end of the mission. The average age of patients was 46.9 years. The average operative time was 116 min, and all patients had local nerve blocks. It included 45 health work providers.It is safe to perform outpatient international surgery during the pandemic while following pre-selected precautions.

Highlights • Hemodynamically stable gunshot wound patients may be managed without retrieval of the bullet. • Nearly 90% of patients with cardiac bullet emboli on initial presentation are hemodynamically stable. • Non-operative management of stable patients includes intensive observation and additional imaging to localize the bullet., Gunshot wounds to the cardiac region usually result in devastating injuries. However, if bullets embolize into the myocardium without significant damage to the organ, optimal evaluation and management remains unclear. We present the case of a hemodynamically stable gunshot wound patient who presented with a bullet to the heart. Sternotomy revealed that the bullet had embolized through the superior vena cava and embedded into the apex of the right ventricle. The patient was managed without retrieval of the bullet and continues to be well despite a retained intracardiac bullet. We discuss cases of bullet embolization to the heart and the emergence of minimally-invasive approaches for management.

An elderly patient aged 70 presented with a level I trauma after being struck by a motor vehicle traveling at unknown speed. The patient was found down and unresponsive by emergency medical services (EMS) with a Glasgow Coma Scale (GCS) score of 3 and was subsequently intubated. An intraosseous (IO) catheter was placed by EMS in the left proximal tibia and fluid resuscitation was started en route. On primary survey, the airway was secured with orotracheal intubation; bilateral breath sounds were auscultated; and correct placement was confirmed with end tidal CO2. Distal pulses were noted with a blood pressure of 135/70 mm Hg and a heart rate of 94 beats/min. The patient’s GCS score improved to 7T (E1V1TM5) in the trauma bay with localization to pain of the bilateral upper extremities. Pupils were 3 mm symmetric and reactive. Secondary survey was significant for bilateral periorbital hematomas and epistaxis, distended abdomen without signs of external trauma, and bilateral knee abrasions. Chest and pelvic X-rays failed to show displaced fractures. The patient was subsequently taken for complete body CT scan. A finding of moderate volume of air in the right ventricle (6 cm widest and 0.8 cm deepest) and main pulmonary …

Background: We sought to assess hernia characteristics and classification through comprehensive review of the literature involving broad ligament herniation. Methods: A literature search via MEDLINE and Embase databases was conducted to identify and select broad ligament herniation studies published between January 1, 2000 and September 30, 2020. Extracted data included previous surgical history, previous obstetric history, diagnostic imaging, herniated organ, hernia classification, and repair performed. The reported data has been compared to a unique case of broad ligament herniation that presented to our institution. Results: A total of 44 articles with 49 cases were identified for the study. Eighteen (36.7%) patients had a history of previous abdominal surgery while 29 (59.2%) had a history of previous childbirth. Type I (51.0%) and Type II (18.4%) defects were most commonly reported with most patients reporting only one defect (85.7%) using the Cilley classification. Twenty-nine patients underwent primary laparoscopic repair of the defect while 19 patients underwent exploratory laparotomy. Conclusions: The analysis of previously reported cases adds to the limited literature on broad ligament hernias and highlights the surgical management of this uncommon pathology. It also highlights the need for a broad differential diagnosis when female patients present with pelvic pain or symptoms of small bowel obstruction. The broad ligament should be fully inspected when mesenteric defects are suspected as multiple defects can be present as evidenced by the attached case study.

Peritoneal tuberculosis is difficult to diagnose as it may mimic peritoneal carcinomatosis, which has similar symptomatology. We sought to determine the diagnostic accuracy of computed tomography in differentiating peritoneal tuberculosis versus peritoneal carcinomatosis.The associations of radiological findings in 124 patients with peritoneal carcinomatosis (n = 55) or tuberculosis (n = 69) were determined using Chi-square test. Sensitivity, specificity, positive and negative predictive value, and total diagnostic accuracy of CT imaging, with histopathology as gold standard, was determined. Subgroup analyses to determine these parameters by age (40 years and ≤40 years) and gender (male and female) were performed.Mean age of study population was 44.1 ± 13.2 years with 61 males (49.2%) and 63 females (50.8%). The most common radiological abnormality in both peritoneal carcinomatosis (90.9%) and peritoneal tuberculosis (89.9%) was omental smudging, followed by presence of extraperitoneal mass (81.8%) in carcinomatosis and presence of micro-nodules in tuberculosis (88.4%). The findings significantly different in both the carcinomatosis and tuberculosis groups were high-density ascites, splenic calcification, splenomegaly, lymph node calcifications, micro-nodules, and macro-nodules. The diagnostic accuracy of CT in differentiating peritoneal tuberculosis from peritoneal carcinomatosis was 83.8%; sensitivity and specificity for peritoneal tuberculosis were 88.4% and 78.2%, respectively.The diagnostic accuracy of CT in differentiating peritoneal tuberculosis from peritoneal carcinomatosis revealed an overall diagnostic accuracy of 83.8%. Subgroup analysis revealed that CT may be a more specific diagnostic tool to predict peritoneal tuberculosis in female patients and in those over 40 years old.

Internal hernia is a rare cause of bowel obstruction in patients with no prior surgical history. Laparoscopic repair of a transverse bowel herniation through the foramen of Winslow is the rarest type of internal hernia, with only two case reports published in the literature. In a patient with a history with Crohn’s disease and no prior surgical history, presenting with signs of bowel obstruction, and no inflammatory symptoms, internal hernia should be suspected as one of the causes. Minimally invasive laparoscopic repair is a feasible safe option in those patients, allowing patients to go home the next day postoperatively.

Importance Cardiac tamponade requiring emergent intervention is a possible complication of coronavirus disease 2019 (COVID-19) infection. Favorable clinical outcomes are possible if timely management and drainage are performed unless ventricular failure develops. Observation Cardiac tamponade in COVID-19, based on the limited reported cases, seems to be more common among middle-aged men with observed complications in black and ethnic minorities. Prognosis is worse amongst patients with concomitant ventricular failure. Design and methods This is a case series of three COVID-19 patients complicated by cardiac tamponade, requiring surgical intervention at a single institution in New York. Intervention Pericardial window, Pericardiocentesis. Outcome One patient had recurrence of cardiac tamponade with hemorrhagic component but fully recovered and was discharged home. Two patients developed cardiac tamponade with concomitant biventricular failure, resulting in death. Conclusion and relevance Cardiac tamponade with possible concomitant biventricular failure can develop in COVID-19 patients; incidence seems to be highest at the point of marked inflammatory response. Concomitant ventricular failure seems to be a predictor of poor prognosis.

Morel-Lavallee lesion is a post-traumatic degloving cyst, usually filled with blood, lymph or necrotic tissue, which mostly develops in the area around greater trochanter. Early diagnosis and prompt treatment is essential to prevent further complications, such as compression of surrounding structures. X-rays have limited use and magnetic resonance imaging (MRI) is the modality of choice in diagnosing the lesion. We report a case of a 35-year female presenting with left thigh pain after a fall from motorcycle almost 21/2 years ago. Ultrasound and MRI confirmed the presence of Morel-Lavallee lesion involving the left pelvis and upper thigh. Given the chronicity of lesion and extensive tissue involvement, the patient underwent surgical excision of the lesion with favourable long-term outcomes. In this case report and literature review, we discuss the pathophysiology, clinical presentation, radiological findings and management options for Morel-Lavallee lesion. Key Words: Morel-Lavallee lesion, Post-traumatic cyst, Degloving Injury, Tangential cyst.
