Abdominal trauma, one of the leading causes of death under the age of 45, can be broadly classified into blunt and penetrating trauma, based on the mechanism of injury. Blunt abdominal trauma usually results from motor vehicle collisions, fall from heights, assaults, and sports and is more common than penetrating abdominal trauma, which is usually seen in firearm injuries and stab wounds. In both blunt and penetrating abdominal trauma, an optimized imaging approach is mandatory to exclude life-threatening injuries. Easy availability of the portable ultrasound in the emergency department and trauma bay makes it one of the most commonly used screening imaging modalities in the abdominal trauma, especially to exclude hemoperitoneum. Evaluation of the visceral and vascular injuries in a hemodynamically stable patient, however, warrants intravenous contrast-enhanced multidetector computed tomography scan. Dual-energy computed tomography with its postprocessing applications such as iodine selective imaging and virtual monoenergetic imaging can reliably depict the conspicuity of traumatic solid and hollow visceral and vascular injuries.

BACKGROUND Lightweight portable ultrasound is widely available, especially in inaccessible geographical areas. It demonstrates effectiveness and diagnosis improvement even in field conditions but no precise information about protocols, acquisition time, image interpretation, and the relevance in changing medical conduct exists. The COVID-19 pandemic implied many severe cases and the rapid construction of field hospitals with massive general practitioner (GP) recruitment. OBJECTIVE This prospective and descriptive study aimed to evaluate the feasibility of telemedicine guidance using a standardized multi-organ sonographic assessment protocol in untrained GPs during a COVID-19 emergency in a field hospital. METHODS Eleven COVID-19 in-patients presenting life-threatening complications, attended by local staff who spontaneously requested on-time teleconsultation, were enrolled. All untrained doctors successfully positioned the transducer and obtained key images guided by a remote doctor via telemedicine, with remote interpretation of the findings. RESULTS Only four (36%) general practitioners obtained the appropriate key heart image on the left parasternal long axis window, and three (27%) had an image interpreted remotely on-time. The evaluation time ranged from seven to 42 minutes, with a mean of 22.7 + 12. CONCLUSIONS Telemedicine is effective in guiding GPs to perform portable ultrasound in life-threatening situations, showing effectiveness in conducting decisions.

ABSTRACT Introduction With blunt and penetrating trauma to the chest, warfighters and civilians frequently suffer from punctured lung (pneumothorax) and/or bleeding into the pleural space (hemothorax). Optimal management of this condition requires the rapid placement of a chest tube to evacuate as much of the blood and air as possible. Incomplete drainage of blood leading to retained hemothorax may be the result of the final tube tip position not being in contact with the blood collections. To address this problem, we sought to develop a “steerable” chest tube that could be accurately placed or repositioned into a specific desired position in the pleural space to assure optimal drainage. An integrated infusion cannula was added for the instillation of anticoagulants to maintain tube patency, thrombolytics for clot lysis, and analgesics for pain control if required. Materials and Methods A triple-lumen tube was designed to provide a channel for a pull-wire which was wound around an axle integrated into a small proximal handle and controlled by a ratcheted thumbwheel. Tension on the wire creates an arc on the tube that allows for positioning. In vitro testing focused on the relationship between the tension on the pull-wire and the resultant arc. Two adult cadavers and two anesthetized pigs were used to study the feasibility of accurate tube placement. After a brief training session, providers were asked to place tubes inferiorly along the diaphragm where blood was anticipated to accumulate or at the apex of the lung for pneumothorax. Success was determined with fluoroscopic images and was judged as a tube tip lying in the targeted position. Results The design was prototyped with an extruded polyvinyl chloride multilumen tube and a 3D printed tensioning handle. In vitro studies showed that one turn of the thumbwheel created 70° to 90° of arc of the tube. Cadaver and animal studies showed consistent success in the desired placement of the tube at or near the lateral diaphragm or in the apex. Attempts were also successful by surgical residents with minimal training. Conclusions Initial preliminary studies on a novel steerable chest tube have demonstrated the ability to appropriately position the tube in a desired location. The addition of an extendable cannula will allow for safe clot lysis or maintained tube patency. Additional studies are planned to confirm the benefit of this device in preventing retained hemothorax.

Background: Traumatic arterio-enteric fistula is predominantly seen after penetrating trauma with only 21 reported cases documented in the past 25 years. They may present in an acute or delayed manner with upper or lower gastrointestinal bleed. A detailed clinical examination with requisite imaging can help in detecting such injuries. Case Description: Case 1: A 20-year-old gentleman, presented with penetrating stab injury to the gluteal region with bleeding per rectum. Imaging revealed evidence of injury to the inferior rectal artery which was found to be communicating with the extraperitoneal portion of the rectum. He was managed with a combination of endovascular and open surgery with a successful outcome. Case 2: A 29-year-old gentleman, presented in a delayed manner 2 weeks after a gunshot wound to the gluteal region, which was managed operatively in another hospital. He developed a massive lower gastrointestinal bleed 2 weeks after presentation. Imaging revealed evidence of a pseudoaneurysm of the inferior gluteal artery which had a fistulous communication with the gastrointestinal tract leading to bleeding. It was managed by endovascular techniques successfully. Conclusion: Arterio-enteric fistulas following trauma are rare phenomena and they need a high index of suspicion for diagnosis. Once diagnosed, they can be managed based on their location and patient physiology by interventional techniques, surgery, or a combination of the two.

AbstractThe liver is the second most commonly involved solid organ (after spleen) to be injured in blunt abdominal trauma, but liver injury is the most common cause of death in such trauma. In patients with significant blunt abdominal injury, the liver is involved approximately 35 to 45% of the time. Its large size also makes it a vulnerable organ, commonly injured in penetrating trauma. Other than its position and size, the liver is surrounded by fragile parenchyma and its location under the diaphragm makes it vulnerable to shear forces during deceleration injuries. The liver is also a vascular organ made of large, thin-walled vessels with high blood flow. In severe hepatic trauma, hemorrhage is a common complication and uncontrolled bleeding is usually fatal. In fact, in patients with severe abdominal trauma, liver injury is the primary cause of death. This article reviews the clinical presentation of patients with liver injury, the grading system for such injuries that is most frequently used, and management of the patient with liver trauma.

Background: Clinical staging systems for hidradenitis suppurativa (HS) have poor interrater reliability and may underestimate disease activity. Sonographic staging systems may overcome these challenges, but conventional ultrasound (US) machines are expensive and bulky. Portable (p)US may facilitate the integration of sonography into routine practice. Objectives: To assess the ability of a novel smartphone-linked pUS device to identify key sonographic lesions of HS. Methods: The charts of 16 patients with HS who were assessed with pUS at the outpatient Dermatology and Wound Care Clinics of a university hospital center were retrospectively reviewed. Clinical and sonographic images of the affected areas were examined. The main outcome measures were the number of patients with identifiable sonographic lesions and the number of patients with subclinical lesions detected by pUS. Results: All 3 key sonographic lesions of HS were identifiable with pUS. Sonographic lesions were identified in 10 patients (62.5%). Subclinical lesions were identified in 2 patients (12.5%); in both cases, this affected management decisions. Conclusions: We demonstrate the ability of pUS to identify the key sonographic lesions of HS. pUS is a simple and affordable way to integrate HSUS into clinical and research settings, with clear potential benefits to patients.
