Background: Emergency surgical repair is the standard approach to the management of an incarcerated abdominal wall hernia (IAWH). In cases of very high-risk patients, manual closed reduction (MCR) of IAWH may prevent the need for emergency surgery.

Objectives: To evaluate the safety, success rate, and complications of MCR in the management of IAWH conducted in an emergency department.

Methods: The data of all patients who underwent MCR between 2012 and 2018 were retrospectively collected. Patient demographics, presenting symptoms, clinical parameters, and management during the hospitalization were retrieved from the medical charts.

Results: Overall, 548 patients underwent MCR during the study period. The success rate was 25.4% (139 patients). One patient had a complication that required a laparotomy 2 days after his discharge. A recurrent incarceration occurred in 23%, 60% of them underwent successful repeated MCR and the others underwent emergency surgery. Six patients (1.4%) had a bowel perforation after a failed MCR.

Conclusions: MCR can be performed safely in the emergency department and should be consider as an option to treat IAWH, especially in high operative risk patients

Background: Extra peritoneal packing (EPP) is a quick and highly effective method to control pelvic hemorrhage.

Objectives: To determine whether EPP can be as safely and efficiently performed in the emergency department (ED) as in the operating room (OR).

Methods: Retrospective study of 29 patients who underwent EPP in the ED or OR in two trauma centers in Israel 2008–2018.

Results: Our study included 29 patients, 13 in the ED-EPP group and 16 in the OR-EPP group. The mean injury severity score (ISS) was 34.9 ± 11.8. Following EPP, hemodynamic stability was successfully achieved in 25 of 29 patients (86.2%). A raise in the mean arterial pressure (MAP) with a median of 25 mmHg (mean 30.0 ± 27.5, P < 0.001) was documented. All patients who did not achieve hemodynamic stability after EPP had multiple sources of bleeding or fatal head injury and eventually succumbed. Patients who underwent EPP in the ED showed higher change in MAP (P = 0.0458). The overall mortality rate was 27.5% (8/29) with no difference between the OR and ED-EPP. No differences were found between ED and OR-EPP in the amount of transfused blood products, surgical site infections, and length of stay in the hospital. However, patients who underwent ED-EPP were more prone to develop deep vein thrombosis (DVT): 50% (5/10) vs. 9% (1/11) in ED and OR-EPP groups respectively (P = 0.038).

Conclusions: EPP is equally effective when performed in the ED or OR with similar surgical site infection rates but higher incidence of DVT

Background: The novel coronavirus disease (COVID-19) pandemic changed medical environments worldwide.

Objectives: To evaluate the impact of the COVID-19 pandemic on trauma-related visits to the emergency department (ED).

Methods: A single tertiary center retrospective study was conducted that compared ED attendance of patients with injury-related morbidity between March 2020 (COVID-19 outbreak) and pre-COVID-19 periods: February 2020 and the same 2 months in 2018 and 2019.

Results: Overall, 6513 patients were included in the study. During the COVID-19 outbreak, the daily number of patients visiting the ED for acute trauma declined by 40% compared to the average in previous months (P < 0.01). A strong negative correlation was found between the number of trauma-related ED visits and the log number of confirmed cases of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Israel (Pearson's r = -0.63, P < 0.01). In the COVID-19 period there was a significant change in the proportion of elderly patients (7% increase, P = 0.002), admissions ratio (12% increase, P < 0.001), and patients brought by emergency medical services (10% increase, P < 0.001). The number of motor vehicle accident related injury declined by 45% (P < 0.01).

Conclusions: A significant reduction in the number of trauma patients presenting to the ED occurred during the COVID-19 pandemic, yet trauma-related admissions were on the rise

Background: As part of the effort to control the coronavirus disease-19 (COVID-19) outbreak, strict emergency measures, including prolonged national curfews, have been imposed. Even in countries where healthcare systems still functioned, patients avoided visiting emergency departments (EDs) because of fears of exposure to COVID-19.

Objective: To describe the effects of the COVID-19 outbreak on admissions of surgical patients from the ED and characteristics of urgent operations performed.

Methods: A prospective registry study comparing all patients admitted for acute surgical and trauma care between 15 March and 14 April 2020 (COVID-19) with patients admitted in the parallel time a year previously (control) was conducted.

Results: The combined cohort included 606 patients. There were 25% fewer admissions during the COVID-19 period (P < 0.0001). The COVID-19 cohort had a longer time interval from onset of symptoms (P < 0.001) and presented in a worse clinical condition as expressed by accelerated heart rate (P = 0.023), leukocyte count disturbances (P = 0.005), higher creatinine, and CRP levels (P < 0.001) compared with the control cohort. More COVID-19 patients required urgent surgery (P = 0.03) and length of ED stay was longer (P = 0.003).

Conclusions: During the COVID-19 epidemic, fewer patients presented to the ED requiring acute surgical care. Those who did, often did so in a delayed fashion and in worse clinical condition. More patients required urgent surgical interventions compared to the control period. Governments and healthcare systems should emphasize to the public not to delay seeking medical attention, even in times of crises

Background: Surgery is considered the mainstay of treatment for esophageal carcinoma. Transhiatal esophagectomy with cervical esophagogastric anastomosis is considered relatively safe with an oncological outcome comparable to that using the transthoracic approach.

Objectives: To review the results of the first 100 transhiatal esophagectomies performed in a single Israeli center.

Methods: The records of all patients who had undergone transhiatal esophagectomy during the period 2003–2009 were reviewed. The study group comprised the first 100 patients. All patients who had undergone colon or small bowel transposition were excluded. Indications for surgery included esophageal cancer, caustic injury and achalasia.

Results: The median follow-up period was 19.5 months. The anastomotic leakage rate was 15% and all were managed successfully with local wound care. The benign stricture rate was 10% and all were managed successfully with endoscopic balloon dilation. Anastomotic leakage was found to be a risk factor for stricture formation. Overall survival was 54%. Response to neoadjuvant therapy was associated with a favorable prognosis.

Conclusions: Transhiatal esophagectomy is a relatively safe approach with adequate oncological results, as long as it is performed in a high volume center.

Background: The role of endoscopic ultrasound in evaluating the response of esophageal cancer to neoadjuvant chemotherapy is controversial.

Objectives: To evaluate the accuracy of EUS[1] in restaging patients who underwent NAC[2].

Methods: The disease stage of patients with esophageal cancer was established by means of the TNM classification system. The initial staging was determined by chest and abdominal computed tomography and EUS. Patients who needed NAC underwent a preoperative regimen consisting of cisplatin and fluouracil. Upon completion of the chemotherapy, patients were restaged and then underwent esophagectomy. The results of the EUS staging were compared with the results of the surgical pathology staging. This comparison was done in two groups of patients: the study group (all patients who received NAC) and the control group (all patients who underwent primary esophagectomy without NAC).

Results: NAC was conducted in 20 patients with initial stage IIB and III carcinoma of the esophagus (study group). Post-chemotherapy EUS accurately predicted the surgical pathology stage in 6 patients (30%). Pathological down-staging was noted in 8 patients (40%). However, the EUS was able to observe it in only 2 patients (25%). The accuracy of EUS in determining the T status alone was 80%. The accuracy for N status alone was 35%. In 65% of examinations the EUS either overestimated (35%) or underestimated (30%) the N status. Thirteen patients with initial stage I-IIA underwent primary esophagectomy after the initial staging (control group). EUS accurately predicted the surgical pathology disease stage in 11 patients (85%).

Conclusions: EUS is an accurate modality for initial staging of esophageal carcinoma. However, it is not a reliable tool for restaging esophageal cancer after NAC and it cannot predict response to chemotherapy.
