Identifying patients with complicated diverticulitis, is it that complicated?

Objectives: Discriminating simple from complicated diverticulitis solely on clinical bases is challenging. The aim of this study was to identify clinical predictive factor for the need for invasive treatment for patients presenting with acute diverticulitis in the emergency room. Material and Methods: The records of all patients, who were discharged from a university hospital between January 2010 and March 2018 with "diverticulitis" diagnosis, were reviewed. Data collected included clinical features, whether this was a first or recurrent episode, WBC, and Hinchey score. Patients were divided into conservative and invasive treatment groups. Groups were compared by age, sex, BMI, fever, WBC and CT findings. Hinchey score groups were also compared by age, sex, BMI, fever, WBC. Results: A total of 809 patients were included. Mean age was 60.6 years, with 10% below 40 years. Most patients were treated conservatively (95.9%) while only 4.1% were treated invasively. WBC at presentation was significantly higher in those who required invasive treatment in comparison with the conservative group (13.72 vs. 11.46K/uL, p= 0.024). A statistically significant higher WBC was found among patients with a higher Hinchey score (13.16 vs 11.69, p <0.005). No difference between the groups was found in terms of age, sex, fever or BMI. Conclusion: This study showed that patients who present with acute diverticulitis and an elevated WBC are prone to a more severe disease and a higher Hinchey score. Prudence should be taken with these patients, and CT scan is warranted as there is a greater chance that invasive treatment will be required.

Immediate Pneumothorax Diagnosis by Surgical Residents Using Portable Ultrasound.

OBJECTIVE: Feasibility of diagnosis of pneumothorax using handheld ultrasound by non-radiologists shows inconsistent results. The aim of this study is to evaluate the feasibility and accuracy of portable ultrasound for immediate diagnosis of pneumothorax by general surgery residents who underwent short training. METHODS: Patients who presented to the emergency department of a university hospital with suspected pneumothorax between 10/2018 and 12/2019 were included in the study. Patients underwent ultrasound in 2 points of each hemithorax. Sensitivity and specificity for pneumothorax diagnosis by ultrasound and physical examination were calculated and compared with chest computed tomography (CT). Patients in whom a chest tube was placed prior to ultrasound examination and those who did not undergo a CT scan were excluded from the study. RESULTS: A total of 85 patients met the inclusion criteria. Mean age was 40.7 ± 20.2 years. Pneumothorax was found among 46 patients (54%) per chest CT, and of these, 21 (46%) underwent chest tube placement following imaging. Ultrasound showed the highest sensitivity and specificity (95.6% [95% confidence interval {CI} 85.16% to 99.47%] and 97.44% [95% CI 86.40% to 99.67%], respectively). Chest x-ray had the lowest sensitivity (47.8% [95% CI 32.89% to 63.05%]) for pneumothorax detection. Physical examination showed a moderate sensitivity and specificity (82.6% [95% CI 68.58% to 92.18%] and 77.89% [95% CI 60.67% to 88.87%], respectively) for the diagnosis of pneumothorax. CONCLUSIONS: We found high accuracy rates of 2-point ultrasound in immediate pneumothorax diagnosis when performed by surgical residents who underwent a short ultrasound training. This is a fast and repeatable test, and has the potential for successful implementation in prehospital and military scenarios as well, minimizing unnecessary chest tube placements.

Clinical significance of rib fractures' anatomical patterns.

OBJECTIVES: Rib fractures are common and carry significant morbidity. Chest CT provides an accurate mapping of the fractures. The aim of this study is to propose an anatomical classification of rib fractures, and assess their relation to complication development. METHOD: The records of all blunt trauma patients between January 1st 2014 and December 31st 2017 at a university hospital were retrospectively reviewed. Wounded who were hospitalized with rib fractures (two and more) as the primary injury were included in the study. Based on the chest CT scans, the cohort was divided into five groups: upper ribs (1-4) fractures, anterior, lateral and posterior middle ribs (4-7) fractures, and lower ribs (9-12) fractures. Data regarding demographics, complications (pneumothorax, hemothorax, chest drains, pulmonary contusion atelectasis, pneumonia, respiratory failure and death), intensive care admission and hospital stay were collected. RESULTS: A total of 102 wounded were included in the study, with a mean age of 46.3 years. The mean number of fractured ribs per person was 3.82±1.68, and 46 wounded had displaced fractures. Rib fracture distribution was: upper ribs - 13.7%, anterior middle ribs - 28.5%, lateral middle ribs fractures - 27.5%, posterior middle ribs - 14.7%, lower ribs fractures - 15.7%. Wounded sustaining lateral middle ribs fractures had the highest complications rates in relation to any other fracture location group, with 25% respiratory failure rate. CONCLUSIONS: Lateral middle ribs fractures are associated with a higher complication rate and may require closer oabservation.

Percutaneous cholecystostomy in the management of high-risk patients presenting with acute cholecystitis: Timing and outcome at a single institution.

BACKGROUND: Cholecystectomy is the standard of care in acute cholecystitis (AC). Percutaneous cholecystostomy (PC) is an effective alternative for high-risk surgical cases. METHODS: A retrospective analysis is presented of AC patients treated with PC drainage at a single tertiary institution over a 21 month period, assessing outcome and complications. RESULTS: Of 119 patients, 103 had clinical improvement after PC insertion. There were 7 peri-procedural deaths (5.9%), all in elderly high-risk cases. Overall, 56/103 cases (54%) were definitively managed with PC drainage with 41 patients (40%) undergoing an elective cholecystectomy (75% performed laparoscopically). The timing of PC insertion did not affect AC resolution or drain-related complications, although more patients underwent an elective cholecystectomy if PC placement was delayed (>24 h after admission). CONCLUSIONS: In AC, drainage by a PC catheter is a safe and effective procedure. It may be used either as a bridge to elective cholecystectomy or in selected cases as definitive therapy.

Ethical and Surgical Dilemmas in Patients with Neglected Surgical Diseases Visiting a Field Hospital in a Zone of Recent Disaster.

OBJECT: The massive typhoon Haiyan (Yolanda) ripped across the central Philippines on November 8, 2013, and damaged infrastructure including hospitals. The Israeli Defense Forces field hospital was directed by the Philippine authorities to Bogo City in the northern part of the island of Cebu, to assist the damaged local hospital. Hundreds of patients with neglected diseases sought for medical treatment which was merely out of reach for them. Our ethical dilemmas were whether to intervene, when the treatment we could offer was not the best possible. METHODS: Each patient had an electronic medical record that included diagnosis, management and aftercare instructions. We retrospectively reviewed all charts of patients. RESULTS: Over 200 patients presented with neglected chronic diseases (tuberculosis, goiter, hypertension and diabetes). We limited our intervention to extreme values of glucose and blood pressure. We had started anti-tuberculosis medications, hoping that the patients will have an option to continue treatment. We examined 85 patients with a presumed diagnosis of malignancy. Without histopathology and advanced imaging modality, we performed palliative operations on three patients. Eighteen patients presented with inguinal hernia. We performed pure tissue repair on seven patients with large symptomatic hernias. We examined 12 children with cleft lip/palate and transferred two of them to Israel. We operated on one child with bilateral club feet. Out of 37 patients with pterygium, our ophthalmologist repaired the nine patients with the most severe vision disturbance. CONCLUSION: Medical delegations to disaster areas should prepare a plan and appropriate measures to deal with non-urgent diseases.

Glasgow Coma Scale Score in Survivors of Explosion With Possible Traumatic Brain Injury in Need of Neurosurgical Intervention.

Importance: Head injury following explosions is common. Rapid identification of patients with severe traumatic brain injury (TBI) in need of neurosurgical intervention is complicated in a situation where multiple casualties are admitted following an explosion. Objective: To evaluate whether Glasgow Coma Scale (GCS) score or the Simplified Motor Score at presentation would identify patients with severe TBI in need of neurosurgical intervention. Design, Setting, and Participants: Analysis of clinical data recorded in the Israel National Trauma Registry of 1081 patients treated following terrorist bombings in the civilian setting between 1998 and 2005. Primary analysis of the data was conducted in 2009, and analysis was completed in 2015. Main Outcomes and Measures: Proportion of patients with TBI in need of neurosurgical intervention per GCS score or Simplified Motor Score. Results: Of 1081 patients (median age, 29 years [range, 0-90 years]; 38.9% women), 198 (18.3%) were diagnosed as having TBI (48 mild and 150 severe). Severe TBI was diagnosed in 48 of 877 patients (5%) with a GCS score of 15 and in 99 of 171 patients (58%) with GCS scores of 3 to 14 (P < .001). In 65 patients with abnormal GCS (38%), no head injury was recorded. Nine of 877 patients (1%) with a GCS score of 15 were in need of a neurosurgical operation, and fewer than 51 of the 171 patients (30%) with GCS scores of 3 to 14 had a neurosurgical operation (P < .001). No difference was found between the proportion of patients in need of neurosurgery with GCS scores of 3 to 8 and those with GCS scores of 9 to 14 (30% vs 27%; P = .83). When the Simplified Motor Score and GCS were compared with respect to their ability to identify patients in need of neurosurgical interventions, no difference was found between the 2 scores. Conclusions and Relevance: Following an explosion in the civilian setting, 65 patients (38%) with GCS scores of 3 to 14 did not experience severe TBI. The proportion of patients with severe TBI and severe TBI in need of a neurosurgical intervention were similar in patients presenting with GCS scores of 3 to 8 and GCS scores of 9 to 14. In this study, GCS and Simplified Motor Score did not help identify patients with severe TBI in need of a neurosurgical intervention.

Ethical and clinical dilemmas in patients with head and neck tumors visiting a field hospital in the Philippines.

OBJECTIVE: To describe clinical and ethical dilemmas in patients presenting with head and neck (H&N) tumors to a field hospital in the "subacute" period following a typhoon. METHODS: We retrospectively reviewed charts of H&N patients presenting to an integrated Israeli-Filipino medical facility, which was operated more than 11 days. RESULTS: Of the 1,844 adult patients examined, 85 (5 percent) presented with H&N tumors. Of those, 70 (82 percent) were females, with a mean age of 43 ± 15 years. Thyroid neoplasms were the most common tumors (68, 80 percent). Despite limited resources, we contributed to the workup and treatment of several patients. To better illustrate our dilemmas, we present four key patients, in whom we favored diagnostic/therapeutic interventions in two, and opted to defer any intervention in two. CONCLUSIONS: In a relief mission, despite the lack of clinical and pathological staging and questionable continuity of care, surgical interventions can be considered for therapeutic, palliative, and diagnostic purposes.

Evacuation of wounded with intracranial injury to a hospital without neurosurgical service versus primary evacuation to a level I trauma centre.

BACKGROUND: Several studies have shown that delay in neurosurgical intervention worsens the neurologic outcome. However, rapid evacuation of wounded sustaining intracranial injury (ICI) to the nearest hospital may have some advantages, as the nearest hospital ER may be a better environment to prevent a secondary brain injury than the ambulance. Also, evacuation to a referral centre of all the wounded suspected in the field to have ICI will result in high rates of over triage. In order to create a factual basis for triage and resource utilization of wounded with possible ICI, we measured the delay in neurosurgical intervention of wounded with ICI that were evacuated to a hospital without neurosurgery service, the Western Galilee Hospital (WGH), Naharia, Israel, and its impact on morbidity and mortality. METHODS AND MATERIALS: A retrospective case-control study was conducted for a period of 29 months. The study population included wounded over the age of two years, sustaining blunt ICI as diagnosed by CT scan that were evacuated to the WGH and later transferred to a level 1 trauma centre, Rambam Health Care Campus (RHCC), Haifa. Wounded were included only if the abbreviated injury score (AIS) of any other body system did not exceed 2. A control group of 29 wounded (one per month) was matched by random selection of wounded who met the inclusion criteria, primarily evacuated to RHCC and underwent neurosurgical intervention. Demographic data, anatomical characteristics of the injury, physiological parameters of injury severity, treatment at the ER, the schedules of neurosurgical interventions, ICU and hospital stay and discharge destination were recorded. Comparison between the groups was performed by Chi-square test for nominal variables, Fisher's exact test for 2×2 contingency tables, and Student's t test for numeric variables. The statistical significance was set at 5% (p<0.05). RESULTS: 162 wounded that were evacuated to WGH and later transferred to RHCC were included in the study. 31(19.1%) of them required invasive neurosurgical intervention. The wounded that needed neurosurgical intervention were transferred earlier: 165.7 (SD 61.1) min on average from arrival to WGH to arrival RHCC, compared to 217.8 (SD 152.9) min for those who did not need any intervention (p<0.005). The demographic variables, injury characteristics, physiological parameters and ER treatment of the wounded that underwent neurosurgical intervention were similar whether the wounded were transferred from WGH or arrived directly to RHCC. The time passed until neurosurgical intervention, was significantly shorter for wounded admitted directly to RHCC: 2h and 13.9 min (133.9 (SD 71.9)min) on average from admission to intervention compared to 4h and 47.6 min (287.6 (SD 107.5)min) on average from WGH admission to neurosurgical intervention (p<0.001). Lengths of ICU stay and hospital stay were similar in both groups. Two patients from each group died. 12 wounded admitted directly to RHCC group and 8 wounded transferred from WGH were discharged to a neurological rehabilitation. CONCLUSIONS: Only a minority of wounded with an intracranial bleeding require neurosurgical intervention, but primary evacuation of these wounded to a hospital with no neurosurgery service results in an unacceptable delay in neurosurgical intervention. In this study, we did not find that this delay had an influence on prognosis, but a larger sample and a prolonged follow up are probably needed. A faster neurosurgical intervention can be achieved by a direct evacuation from the field to a level 1 trauma centre, or by expedition of the transfer process.

Do pre-hospital trauma alert criteria predict the severity of injury and a need for an emergent surgical intervention?

OBJECTIVE: Efficient triage may have a major influence on mortality and morbidity as well as financial consequences. A continuous effort to improve this decision making process and update the trauma alert criteria is being made. However, criteria for determining the evacuation priority are not well developed. We performed a prospective study to evaluate which pre-hospital parameters identify major trauma victims with an emphasis on a need for emergent surgical procedures. METHODS: A prospective cohort included 601 patients admitted to a level one trauma centre over a three months period. The pre-hospital trauma alert criteria were recorded and set as independent variables. All major surgical procedures were graded in real time as: emergent, urgent, or not urgent. The ISS was calculated after completion of all the diagnostic workup. Patients were classified as major trauma victims if their calculated ISS was 16 or greater, and those needed an urgent intervention or intensive care. The relative risks (RR) for major trauma and a need for an emergent operation were calculated. RESULTS: 243 (40%) patients were classified as having a major trauma. 39 (6.5%) patients required an emergent operative intervention: 24 for an active bleeding, 5 for a pericardial tamponade and 10 for an imminent cerebral herniation. Paramedic judgement and a penetrating injury to the trunk were the most common causes for over triage. However, a penetrating injury to the trunk had been the only clue that the victim needed an emergent operation in five cases. 128 patients had a pre-hospital Glasgow coma score (GCS) ≤ 12. Altered mental status was the most common and a significant predictor of both major trauma (RR of 3.00 with a 95% confidence interval (CI) of 1.98-4.53) and a need for an emergent operation (RR, 95% CI: 4.43, 2.28-8.58). Also, a systolic blood pressure ≤ 90 mmHg was highly associated with an emergent operation (RR, 95% CI: 11.69, 5.85-23.36). CONCLUSION: For determining the evacuation priority, we suggest a triage system based on three major criteria: mental status, hypotension and a penetrating injury to the trunk. Overall, the set of trauma alert criteria system can be further simplified and enable better utilisation of resources.

Triage in mass-casualty events: the Haitian experience.

INTRODUCTION: Mass-casualty triage is implemented when available resources are insufficient to meet the needs of all patients in a disaster situation. The basic principle is to do the maximum good for the most casualties with the least amount of resources. There are limited data to support the applicability of this principle in massive disasters such as the January 2010 earthquake in Haiti, in which the number of patients seeking medical attention overwhelmed the local resources. OBJECTIVE: To analyze the application of a triage system developed for use in a mass-casualty setting with limited resources. The system was designed to admit only those patients who had medical conditions requiring urgent treatment that were within the capabilities of the hospital and had a good chance of survival after discharge. Priority was given to those whose treatment could be administered within a short hospital stay. METHOD: A retrospective, observational review of computerized registration forms of Haitian earthquake victims who sought medical care at a 72-bed field hospital within four to 14 days after the event. An analysis of the efficacy of the triage protocol that was used followed, using length of hospital stay to measure consumption of resources. RESULTS: A total of 1,111 patients were triaged for treatment in the field hospital within 14 days of the earthquake. The median length of stay for all patients for whom data was available was 16 hours (mean = 29.7 hours). The majority of patients (n = 620, 65%) were discharged within 24 hours. Two hundred five patients underwent surgery and were discharged within a median of 39 hours (mean = 52.6 hours); of these, 124 (62%) were discharged within 48 hours. The total mortality of the treated patients was 1.5% (n = 17). CONCLUSIONS: Currently accepted triage principles for the most part are appropriate for efficiently providing medical care in a disaster area with extremely limited resources, but require extensive adaptation to local conditions.

Hard times call for creative solutions: medical improvisations at the Israel Defense Forces Field Hospital in Haiti.

Mass disaster medicine is characterized by the need to manage limited resources that are far inadequate to meet the population's demands. Under these hectic conditions, lack of specific medical equipment is expected and requires improvisation using available items. We describe the innovative use of medical improvisations at the Israel Defense Forces field hospital, working in the earthquake zone, Port-au-Prince, Haiti, on January 2010. Creative solutions were found to several problems in a variety of medical fields: blood transfusion, debridement and coverage of complex wounds, self-production of orthopedic hardware, surgical exposure, and managing maxillofacial injuries. We hope that the methods described will help to inspire medical teams working in disaster regions.

Early disaster response in Haiti: the Israeli field hospital experience.

The earthquake that struck Haiti in January 2010 caused an estimated 230,000 deaths and injured approximately 250,000 people. The Israel Defense Forces Medical Corps Field Hospital was fully operational on site only 89 hours after the earthquake struck and was capable of providing sophisticated medical care. During the 10 days the hospital was operational, its staff treated 1111 patients, hospitalized 737 patients, and performed 244 operations on 203 patients. The field hospital also served as a referral center for medical teams from other countries that were deployed in the surrounding areas. The key factor that enabled rapid response during the early phase of the disaster from a distance of 6000 miles was a well-prepared and trained medical unit maintained on continuous alert. The prompt deployment of advanced-capability field hospitals is essential in disaster relief, especially in countries with minimal medical infrastructure. The changing medical requirements of people in an earthquake zone dictate that field hospitals be designed to operate with maximum flexibility and versatility regarding triage, staff positioning, treatment priorities, and hospitalization policies. Early coordination with local administrative bodies is indispensable.

Is the FAST exam reliable in severely injured patients?

INTRODUCTION: Highly sensitive and accurate for the detection of injuries requiring intervention in haemodynamically unstable patients, FAST may underestimate intra-abdominal injuries in stable patients with blunt abdominal trauma. Diminished accuracy of ultrasound has been reported in different cohorts of multiple injured patients. We hypothesised that multiple injured patients with a high Injury Severity Score (ISS) will have a decreased accuracy of FAST for the assessment of blunt abdominal trauma. METHODS: Data from the trauma registry of a Level 1 trauma centre were retrospectively reviewed. All haemodynamically stable blunt trauma patients who underwent both FAST and CT scan of abdomen from January 1, 2000 to January 1, 2005 were included in the cohort. All patients were divided into three groups according to their ISS: Group 1 included patients with an ISS from 1 to 14, Group 2 included patients with an ISS from 16 to 24, and Group 3 consisted of patients with ISS>or=25. RESULTS: 3181 patients with blunt abdominal trauma included into the study were divided into the three groups according to the ISS. The mean ISS was 7.9+/-3.97, 19.6+/-2.48 and 41.3+/-11.95 in Groups 1, 2 and 3, respectively. The accuracy of ultrasound was 90.6% in the group of patients with the highest ISS (>or=25) compared with 97.5 and 97.1 for Groups 1 and 2 (p<0.001). Similarly, ultrasound had a significantly lower sensitivity, specificity, PPV and NPV for patients in Group 3 compared with the first two groups (p<0.001). There was a significantly lower sensitivity in Group 2 compared with Group 1 (p<0.001), but no differences in specificity, accuracy, PPV or NPV were demonstrated. CONCLUSION: Patients with high ISS are at increased risk of having ultrasound-occult injuries and have a lower accuracy of their ultrasound examination than patients with low and moderate ISS.

Medical consequences of suicide bombing mass casualty incidents: the impact of explosion setting on injury patterns.

BACKGROUND: The increase in the incidence of suicide bombings on urban civilian populations in the recent years necessitates a better understanding of the related epidemiology in order to improve the outcome of future casualties. OBJECTIVE: To characterise the epidemiology of mass casualty incidents following suicide explosions in relation to the surrounding settings. METHODS: This study presents an analysis of the immediate medical consequences of 12 consecutive multiple casualty incidents (MCI's). Both pre-hospital and in-hospital data was assessed for each event including EMS evacuation times, types of injuries, body regions involved, Emergency Department (ED) triage, ED interventions and surgical procedures performed. RESULTS: The average arrival time of the first ambulance to the scene was 6.8+/-2.3 min. The first "urgent" patient was evacuated in average of 7.6+/-5.3 min later, while the last "urgent" patient was evacuated 27.8+/-7.9 min after the explosion. Explosions that occurred in buses had the worst rates of overall mortality (21.2%). However, those who survived closed space explosions suffered from the highest number of severe and moderate (ISS>8) injuries (22.9%). Casualties in this group underwent the largest number of both Emergency Room and Surgical interventions. Of the three settings, open space explosions resulted in the largest numbers of casualties with the smallest percentage of severe injuries or death. CONCLUSIONS: MCIs resulting from suicide explosions can be classified according to the setting of the event since each group was found to have distinct epidemiological characteristics.

Locking plastic tie--a simple technique for securing a chest tube.

A quick and simple technique for securing a chest tube in the prehospital setting is described. The technique makes use of a plastic tie with a self-locking mechanism that is wrapped around the tube and sutured to the skin. The use of a plastic tie is recommended as a valuable component to chest tube kits for use in the prehospital setting.
