UNASSIGNED: Seat belt syndrome (SBS) is a rare condition described as injuries sustained due to thoracic, abdominal, and pelvic compression in the context of traffic accidents. These injuries can range from minor skin abrasions to large lesions of internal organs and spinal cord involvement. Traumatic abdominal wall hernias (TAWH) are one of the injuries that can be associated.
METHODS: A 21-year-old male suffered a severe injury, resulting in complete transection of all abdominal wall musculature due to SBS, with associated visceral injury. Emergency surgery included intestinal and sigmoid colon resection, along with cava vein repair. After a prolonged recovery, a second-stage surgery for abdominal wall reconstruction was planned. Prehabilitation involved botulinum toxin and pneumoperitoneum, with surgical planning utilizing CT scan and 3D reconstruction. The second-stage surgery included transversus abdominis release and placement of double mesh.
UNASSIGNED: Managing traumatic abdominal wall hernias in polytrauma patients necessitates emergent surgery for vital injuries, while reconstructive surgery timing is crucial, with patient preparation being essential. Surgical planning, including 3D reconstructions, enhances accuracy, and safety, with repair technique selection depending on anatomical features. Given our patient\'s athletic background and preoperative vascular CT findings, flapless reconstructive surgery was chosen to mitigate vascular risks.
CONCLUSIONS: The therapeutic approach to traumatic abdominal wall injuries should be individualized to each patient, with a focus on addressing vital injuries first and considering abdominal wall reconstruction surgery at a subsequent stage. Utilizing CT scan with 3D reconstruction can be a valuable tool for preoperative planning in cases involving significant abdominal wall defects.

A rare case of an ascending colon injury and ileal perforation in a 34-year-old male patient due to blunt abdominal trauma caused by a road traffic accident is reported in this study. This paper reports the clinical and imaging findings of seat belt syndrome. The seat belt syndrome primarily involves soft tissue injury; however, lacerations of the colon, small intestine, and mesentery have rarely been reported in the literature. However intestinal injuries, including bowel perforation and mesenteric injuries due to seat belt syndrome, must not be underestimated because they usually require emergency laparotomy because of accompanying peritonitis and hemorrhaging, and can be lethal if left untreated. Therefore, when an ascending mesocolon hematoma and free gas in the peritoneal cavity are present, gastrointestinal perforation due to seat belt syndrome should be suspected. In this case, gastrointestinal perforation was suspected based on the computed tomography findings, and emergency surgery was performed; the patient\'s course was uneventful without any postoperative complications. Early diagnosis and management are essential to prevent associated morbidity and mortality.

UNASSIGNED: Seat belt syndrome is associated with multiple visceral injuries and vertebral burst fractures. Small Intestinal perforations are seen in 5-15 % of blunt abdominal trauma. In our case, we will report a case that presented small intestinal perforation and thoracic vertebral fracture caused by a different mechanism.
METHODS: Previously healthy 48-year-old male presented to the emergency department following falling from 15 feats height. He was a paraplegic with a sensory level at T12. He did not have a clinical feature of spinal shock. He was complaining of epigastric and central abdominal pain and tenderness and was diagnosed to have a proximal Jejunal perforation associated with an unstable fracture of T12 causing spinal compression. Open intestinal repair followed by a posterior spinal exploration and pedicle screw fixation done.
UNASSIGNED: Violent injury due to different mechanisms can have similar injuries to Seat belt syndrome. Ultrasonography is used to detect pneumoperitoneum, but the Contrast study is the gold standard to detect visceral injuries. The surgical approach to visceral injury depends on the patient\'s condition. But the laparoscopic approach has a more favorable postoperative outcome than open access.
CONCLUSIONS: Intestinal perforations associated with the neurological deficit are difficult to identify in an initial clinical assessment. Thoracolumbar fractures can associate with small bowel injuries during high-velocity trauma. Early identification and repair of the intestinal injury are important to prevent devastating complications and to improve neurological recovery after spinal surgery.

BACKGROUND: Protective devices such as seat belts and airbags have improved the safety of motor vehicle occupants, but limited data suggest they may be associated with increased blunt bowel (small bowel or colon) injuries (BI). Unfortunately, this risk is unquantified.
METHODS: We analyzed the National Trauma Data Bank (2017-2019) using ICD-10 codes to identify adult motor vehicle occupants with BI who underwent surgical repair. We used logistic regression modeling to compare the risk of undergoing surgical repair for BI after using a protective device.
RESULTS: Of 2,848,592 injured patients, 475,546 (16.7%) were motor vehicle occupants. Only 1.2% (n = 5627/475,546) of patients underwent a bowel repair or resection. Using a seat belt only was associated with an adjusted OR of 2.09 (95% CI 1.91, 2.28) for undergoing a bowel repair/resection when adjusting for Injury Severity Score (ISS) and age. Airbag deployment without a seat belt had an adjusted OR of 1.46 (95% CI 1.31, 1.62), while both devices combined conferred an OR of 3.27 (95% CI 3.02, 3.54). However, using a seat belt was protective against death with an OR of 0.50 (95% CI 0.48, 0.53), adjusted for age, sex, Charlson Comorbidity Score, and ISS.
CONCLUSIONS: Seat belts and airbags are essential public health safety interventions and protect against death in motor vehicle-associated injuries. However, patients involved in MVCs with airbag deployment or while wearing a seat belt are at an increased risk of bowel injury requiring surgery compared to unrestrained patients, despite these events being relatively uncommon.

Seat belt syndrome (SBS) represents all injury profiles associated with seat belt injuries and motor vehicle crashes (MVCs). Seat belt syndrome classically presents with a superficial seat belt sign that may signify deeper intra-abdominal and/or spinal involvement. The amount of force transmitted from the restraint to the passenger ultimately dictates the amount and severity of the injury. We present a unique case of a 59-year-old female involved in a motor vehicle crash with multiple traumatic injuries, including seat belt syndrome, abdominal wall transection, and bowel injuries. She later had reconstruction of her traumatic abdominal wall hernias (TAWHs). Three unique approaches were used in the management of her traumatic abdominal wall hernias: (1) preoperative Botulinum toxin (Botox) injections, (2) operative use of biologic and bioabsorbable meshes in contaminated fields, and (3) postoperative physical therapy and body positioning. The patient did not experience any recurrence of these hernias after her abdominal wall reconstruction and remains alive at the time this case was written. The diagnostic criteria and surgical management of traumatic abdominal wall hernias have yet to be established, and the case presented here provides approaches that should serve as future areas for study.

We report herein our experience with a 10-year-old girl who incurred injuries consistent with seat belt syndrome. The patient was involved in a low-speed motor vehicle accident while restrained in a three-point belt (shoulder and lap belts). She complained of abdominal pain and developed tenderness and abdominal guarding. On admission, enhanced computed tomography (CT) demonstrated a fluid collection in the pelvis and a fractured vertebra in the lumbar spine. The following day, her C-reactive protein and serum amylase levels were elevated and plain CT demonstrated free air in the left side of the abdominal cavity. A ruptured jejunum was detected on laparoscopy. The involved segment of intestine was resected and an end-to-end anastomosis performed. She had an uneventful post-operative course. On post-operative day 14, she was transferred to another facility to undergo therapy for her spinal fracture. After completing conservative therapy, she was discharged 5 weeks after the initial injury.

Intestinal injuries in seat belt syndrome are relatively uncommon but can be potentially lethal due to accompanying peritonitis and hemorrhaging. It can be difficult to identify the exact injury sites of the intestine as multiple areas are often damaged and massive intraperitoneal hemorrhaging may make it challenging to determine causal bleeding points of mesenteric injuries. This study aimed to clarify the incidence and distribution of intestinal injuries in seat belt syndrome.
We retrospectively reviewed the clinical records of 25 patients who underwent laparotomy for suspected intestinal injuries due to seat belt syndrome during a frontal impact. The incidence and distribution of the sites of intestinal injuries, as well as associated injuries, were investigated. Intestinal injuries were divided into bowel and mesenteric injuries. Additionally, bowel injuries were classified into two types: perforation and non-perforation (seromuscular tears/intramural hematomas). Regarding the injured sites, the small intestine was divided into the following three parts: (1) the ligament of Treitz (100-cm distal from the ligament [proximal jejunum]), (2) the ileocecal valve (100-cm proximal from the valve [distal ileum]), and (3) the intermediate area between those two regions (jejunoileal junction).
In total, there were 64 major injuries among 25 patients requiring surgical intervention: 34 bowel injuries (20 perforations and 14 non-perforations) and 30 mesenteric injuries. Significantly more bowel perforations occurred in the small intestine (1 [interquartile range (IQR), 0-1]) than in the large intestine (0 [IQR, 0-0]) (p = 0.003). Similarly, significantly more mesenteric injuries occurred in the small intestine (1 [IQR, 0-1.25]) than in the large intestine (0 [IQR, 0-0]) (p < 0.001). Specific sites of the mesenteric injuries in the small intestine included the jejunoileal junction (0 [IQR, 0-1]) and distal ileum (0 [IQR, 0-1]); the jejunoileal junction was significantly more vulnerable than the proximal jejunum (0 [IQR, 0-0]) (p = 0.015).
In patients with seat belt syndrome, the small intestine was more vulnerable to perforation and mesenteric injury than the large intestine. Additionally, for mesenteric injuries, the jejunoileal junction was more likely to be damaged than the proximal jejunum.

Seat belts are considered the reason for seat belt syndrome, which mainly occurs during rapid deceleration in motor vehicle accidents. Seat belt syndrome is characterized by contusion of the front torso, intrathoracic or intraabdominal organ injuries, and spinal thoracic or lumbar chance fractures.
This case study presents a 21-year-old female who was injured by a lap-type seat belt and diagnosed with seat belt syndrome after an airplane landing accident. She underwent surgery for lumbar chance fracture and abdominal injury. We discussed the possible harmful effects of lap seat belts in passenger seats on airplanes.
While an airplane is in a flying position, a lap seat belt functions to protect the passenger from any turbulence. However, during the landing or take-off phase, it may not be enough to fully protect the passenger, especially during sudden deceleration accidents, which cause seat belt injuries and head traumas. Therefore the unique design of a double functional passenger seat belt harness, along with a 3- or 4-point buckle protruding from the shoulder, can serve as a more favorable protective measure in limiting the severity of injury a passenger receives. After the plane has taken off, the diagonal seat belt can then be unlocked, leaving the lap seat belt to remain firmly in place and secured.

Seat belt aorta is rare and difficult to manage. The lack of data and follow-up increases the complexity of treating such patients. We aimed to create a decision algorithm by reviewing our current experience and analyzing the presentation and management of our patients.
We performed a descriptive case series based on retrospective analysis of all consecutive patients admitted with the diagnosis of seat belt aorta from 2008 to 2018. Seat belt aorta was defined as any blunt abdominal aortic lesion resulting from a seat belt compression mechanism after a car accident.
Nine consecutive patients were admitted with the diagnosis of seat belt aorta, all of whom developed lesions in the infrarenal aorta. Eight patients were assessed in the acute phase and one patient presented with late-onset symptoms. Associated injuries were present in all acute patients, and seat belt sign and small bowel injury were present in 88%. One patient presented with a small intimal tear and was treated conservatively. All other patients diagnosed with large intimal flaps (seven patients) and pseudoaneurysm (one patient) underwent open repair in five cases and endovascular repair in three cases. In-hospital mortality for the acute cases was 38%, with no mortality seen during follow-up. Two patients submitted to endovascular repair required reinterventions.
Seat belt aorta is a deadly condition, frequently associated with blunt thoracoabdominal trauma with concomitant injuries; the presence of a seat belt sign or lower limb ischemia must lead to a high diagnostic suspicion. Management must take into account the other concomitant injuries. Follow-up is crucial as most patients are young; they may develop complications and subsequently require further intervention.

BACKGROUND: Seat belt marks are seen frequently on occupants after motor vehicle accidents. Over the years, the clinical significance of these marks has changed as restraint systems have evolved. With modern restraint systems, signs of a compromised occupant-restraint relationship are an important and easily identified bedside finding.
OBJECTIVE: We sought to learn to recognize seat belt marks that demonstrate an abnormal occupant-restraint system relationship and to cultivate an understanding of significant soft tissue biomechanical loading associated with marks caused by a compromised occupant-restraint relationship.
CONCLUSIONS: A review of case studies from the literature combined with forensic work demonstrate a strong correlation between significant injury and improper seatbelt use. When evidence of a compromised occupant-restraint relationship exists, incorporating computed tomography angiography and observation may be clinically indicated.
CONCLUSIONS: The recognition of seat belt marks made by a compromised occupant-restraint relationship is an important finding that allows risk stratification of the patient at the bedside. Further investigation with a prospective trial at a trauma center is warranted.
