Trauma laparotomy after blunt abdominal trauma is conventionally indicated for patients with features of hemodynamic instability and peritonitis to achieve control of hemorrhage and control of spillage. In addition, surgery is clearly indicated for the repair of posttraumatic diaphragmatic injury with herniation. Some other indications for laparotomy have been presented and discussed. Five patients with blunt abdominal injury who underwent laparotomy for nonroutine indications have been presented. These patients were hemodynamically stable and had no overt signs of peritonitis. Three patients had solid organ (spleen, kidney) infarction due to posttraumatic occlusion of the blood supply. One patient had mesenteric tear with internal herniation of bowel loops causing intestinal obstruction. One patient underwent surgery for traumatic abdominal wall hernia. In addition to standard indications for surgery in blunt abdominal trauma, laparotomy may be needed for vascular thrombosis of end arteries supplying solid organs, internal or external herniation through a mesenteric tear or anterior abdominal wall musculature, respectively.

Few studies have investigated risk factors for recurrence of blunt traumatic abdominal wall hernias (TAWH). Twenty trauma centers identified repaired TAWH from January 2012 to December 2018. Logistic regression was used to investigate risk factors for recurrence. TAWH were repaired in 175 patients with 21 (12.0%) known recurrences. No difference was found in location, defect size, or median time to repair between the recurrence and non-recurrence groups. Mesh use was not protective of recurrence. Female sex, injury severity score (ISS), emergency laparotomy (EL), and bowel resection were associated with hernia recurrence. Bowel resection remained significant in a multivariable model. Female sex, ISS, EL, and bowel resection were identified as risk factors for hernia recurrence. Mesh use and time to repair were not associated with recurrence. Surgeons should be mindful of these risk factors but could attempt acute repair in the setting of appropriate physiologic parameters.

Spigelian hernia (SH) is an infrequent aponeurotic defect in Spiegel’s semilunar line. The literature on pediatric SH is scarce. A comprehensive review of the previous literature was conducted. Eligible studies were identified by searching primary medical bibliography databases, and a pooled analysis of published case-level data was performed. Medians and interquartile ranges were used to describe the quantitative variables and proportions for categorical variables. The Kruskal–Wallis, Mann–Whitney U, and Fisher’s exact tests were used to compare group variables. Spearman’s and Pearson’s correlation analyses were used to assess the degree of correlation between variables, while Cramér’s V was applied to evaluate the degree of association among the variables. A p-value < 0.05 (two-tailed) was considered statistically significant. Our search identified 82 publications reporting on 123 patients (106 male, 86.2%), with an age range of 0–21 years. Forty-seven patients (38.2%) had a left-sided SH, fifty-six (45.5%) had a right-sided SH, and thirteen (10.6%) had a bilateral SH. Traumatic SH, mostly from bicycle injuries, accounted for 45 cases (36.6%), while 41 (33.3%) were associated with undescended testis (UDT). In this series of published cases, hernia incarceration/strangulation (I/S) was reported in 15 patients (12.2%), who were significantly younger (p = 0.02). Surgical correction was performed in 95 cases (77.2%), 14 of them laparoscopically, with a 35.7% conversion rate. Eight cases (6.5%) were managed conservatively. Overall, outcomes were favorable. SH is an infrequent pediatric condition that, based on the synthesized literature, predominantly affects males. The published cases suggest two main clinical phenotypes: a congenital form, often linked to ipsilateral UDT, and an acquired form, typically resulting from trauma. Analysis of the reported data indicates a higher risk of incarceration in early childhood. Surgical treatment is the most frequently reported approach with generally favorable outcomes, whereas the evidence for conservative management remains limited. This comprehensive review highlights the dual nature of pediatric SH and underscores the need for a high index of suspicion in relevant clinical scenarios.

Traumatic abdominal wall injuries encompass a broad clinical and radiological spectrum and are identified in approximately 9% of blunt trauma patients. The most severe form of abdominal wall injury—a traumatic abdominal wall hernia—is seen in less than 1.5% of blunt abdominal trauma patients. However, the incidence of concurrent intra-abdominal injuries in these patients is high and can result in significant morbidity and mortality. Although the diagnosis of abdominal wall injuries is typically straight forward on CT, associated injuries may distract the interpreting radiologist in more subtle cases. Thus, it is important for the radiologist to identify abdominal wall injuries and their associated injuries on admission CT, as these injuries typically require surgical correction early in the course of their management. Untreated abdominal wall injuries subject the patient to increased risk of delayed bowel incarceration and strangulation. Therefore, it is important for the radiologist to be knowledgeable of injuries to the abdominal wall and commonly associated injuries to provide optimal patient triage and expedite management.

Background Blunt abdominal traumas are often associated with intra-abdominal injuries and pelvic fractures. Traumatic abdominal wall hernias due to disruption of the abdominal wall muscles may be overlooked. Delayed diagnosis can lead to hernia related complications. Case presentation We present two cases of high kinetic trauma with pelvic fractures and acute traumatic abdominal wall herniation. Both of these cases suffered from a delayed diagnosis and needed surgery to treat the symptomatic herniation. Conclusion Clinical reassessment and appropriate medical imaging are mandatory in patients with high kinetic abdominal blunt traumas and associated pelvic fracture, in order to prevent delayed diagnosis and possible complications.

Introduction spigelian hernias are rare anterior abdominal wall hernias, accounting for less than 2% of all hernias. Traumatic spigelian hernias are exceptionally rare and typically result from blunt abdominal trauma. Case presentation We report a case of a 15-year-old male who presented with right lower quadrant abdominal pain following blunt trauma. Imaging revealed a traumatic spigelian hernia with an associated ileal mesenteric defect. The patient underwent exploratory laparotomy and hernia repair with excellent postoperative recovery. Conclusion This case highlights the importance of early recognition and surgical management of traumatic spigelian hernias, particularly when associated with underlying mesenteric defects.

Pediatric traumatic abdominal wall hernias (TAWHs) are rare injuries that result from both low- and high-energy trauma. TAWHs have a wide presentation, ranging from isolated hernias to cases involving severe associated intraabdominal injury. With a limited number of case reports, correct management and prediction of outcome are difficult. This case report describes a 5-year-and-9-month-old girl who developed a TAWH following a 2-m fall onto a stick. Computed tomography of the abdomen was avoided due to the low-energy mechanism, absence of pain, and lack of physical findings beyond a minor abrasion. Serial sonographic evaluation confirmed bowel herniation without evidence of associated intraabdominal injury. After an observational period of 24 hours without complications, the patient was discharged. Ten days later, an uncomplicated elective open herniotomy was performed. Two-month follow-up revealed no additional contacts to the hospital.

BackgroundBlunt impact-induced traumatic abdominal wall hernia (TAWH) is an uncommon pediatric surgical problem classically associated with handlebar injury but increasingly seen with seatbelt use in motor vehicle collisions (MVC). Herein we describe the largest case series of pediatric TAWH to date and review the literature to establish the unique syndromic characteristics of MVC-associated TAWH.MethodsIn this single-institution series, we discuss four pediatric patients, all with seatbelt-associated TAWH after high-speed MVC characterized by full-thickness disruption of the lateral abdominal wall. We then performed a review of the literature to identify additional pediatric MVC-associated TAWH and define the characteristics of patients who sustained this unique injury.ResultsIn addition to the four patients in our case series, five additional pediatric patients presenting with TAWH after restrained MVC were identified in the literature. Of these nine patients, eight (89%) presented with an obvious seatbelt sign (bruising/laceration to the abdominal wall). Six (67%) had associated injuries typical of the seatbelt syndrome, including four spinal flexion injuries (44%) and five bowel injuries requiring repair or resection (56%). Overall, 56% of seatbelt-associated TAWH occurred in children with a BMI percentile > 95%.ConclusionsIn this case series and literature review, we note a high rate of seatbelt syndrome injuries in pediatric patients presenting with TAWH after restrained MVC. Suspicion for TAWH should be high in children presenting with a seatbelt sign and should trigger a low threshold for pursuing additional axial imaging.Level of evidenceLevel IV; case series.

Case presentation: A 24-year-old female presented to the emergency department with diffuse abdominal pain after involvement as a restrained driver in a motor vehicle collision (MVC). Computed tomography of the abdomen revealed a traumatic abdominal wall hernia due to rectus wall rupture with complete bowel herniation.Discussion: A traumatic abdominal wall hernia is a rare complication of blunt abdominal trauma that is typically associated with injury from a motorcycle handlebar but is more commonly seen after a MVC. It is important to consider this diagnosis when evaluating patients with abdominal pain after blunt abdominal trauma from either of these mechanisms.

Traumatic abdominal wall hernia (TAWH) is a rare form of herniation caused by blunt trauma that can lead to intestinal obstruction. This report details a rare case of delayed mechanical ileus resulting from TAWH due to an acetabular fracture. The patient was successfully treated with laparoscopic closure of the peritoneal orifice, followed by orthopaedic repair of the fracture. The presented scenario underlines the importance of timely diagnosis and interdisciplinary collaboration in addressing complex TAWH cases.
