    Introduction Ostriches typically avoid humans in the wild, since they correctly assess humans as potential predators, and, if approached, often run away. However, ostriches may turn aggressive rather than run when threatened, especially when cornered, and may also attack when they feel the need to defend their offspring or territories. Presentation of case A 71-year-old male patient presented with intra abdominal injury sustained from being kicked in the abdominal wall by an ostrich. During laparotomy, were found free peritoneal effusion and perforation of the small intestine. Discussion The clinical history and physical examination are extremely important for diagnostic and therapeutic decision making. CT-scan is the most accurate exam for making diagnosis. Surgery is the treatment of choice, and is always indicated when there is injury to the hollow viscera. In general it is possible to suture the defect. Conclusion In cases of blunt abdominal trauma by animals is necessary to have a low threshold of suspicion for acute abdomen. PMID:25685344

    INTRODUCTION Traumatic abdominal wall hernia (TAWH) and traumatic abdominal aortic injury (TAAI) are two uncommon complications secondary to blunt trauma. In both TAWH and TAAI, reported cases are often associated with poly-trauma. TAWH may be initially missed if more pressing issues are identified during the patient's primary survey. TAAI may be an incidental finding on imaging or, if severe, a cause of an acute abdomen and hemodynamic abnormality. PRESENTATION OF CASE A 54-year-old white male suffered a TAWH and TAAI (pseudoaneurysm) due to severe blunt trauma. TAWH was apparent on physical exam and the TAAI was suspected on computed tomography (CT). The patient's TAWH was managed with a series of abdominal explorations and the TAAI was repaired with endovascular stenting. DISCUSSION TAWH and TAAI are commonly due to severe blunt trauma from motor vehicle collisions. Diagnosis is made through physical exam, imaging studies, or surgical exploration. A variety of surgical techniques achieve technical success. CONCLUSION The patient with blunt trauma to the abdomen is at risk for TAWH and TAAI, which are often associated with other injuries. Investigations should include thorough clinical exam through secondary survey and radiologic imaging in the hemodynamically normal patient. PMID:25437685

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

    Pneumobilia denotes an abnormal connection between the gastrointestinal and the biliary tracts. In the absence of surgically created anastomosis between the bowel and the bile duct, the common causes for pneumobilia are gallstone obstruction, endoscopic interventions or emphysematous cholecystitis. We present the case of a young male with traumatic pneumobilia with gastric perforation and a tear in the mesentery of the small gut following penetrating trauma in the form of stab in the abdomen.

  5. Lateral Abdominal Wall Reconstruction

    Lateral abdominal wall (LAW) defects can manifest as a flank hernias, myofascial laxity/bulges, or full-thickness defects. These defects are quite different from those in the anterior abdominal wall defects and the complexity and limited surgical options make repairing the LAW a challenge for the reconstructive surgeon. LAW reconstruction requires an understanding of the anatomy, physiologic forces, and the impact of deinnervation injury to design and perform successful reconstructions of hernia, bulge, and full-thickness defects. Reconstructive strategies must be tailored to address the inguinal ligament, retroperitoneum, chest wall, and diaphragm. Operative technique must focus on stabilization of the LAW to nonyielding points of fixation at the anatomic borders of the LAW far beyond the musculofascial borders of the defect itself. Thus, hernias, bulges, and full-thickness defects are approached in a similar fashion. Mesh reinforcement is uniformly required in lateral abdominal wall reconstruction. Inlay mesh placement with overlying myofascial coverage is preferred as a first-line option as is the case in anterior abdominal wall reconstruction. However, interposition bridging repairs are often performed as the surrounding myofascial tissue precludes a dual layered closure. The decision to place bioprosthetic or prosthetic mesh depends on surgeon preference, patient comorbidities, and clinical factors of the repair. Regardless of mesh type, the overlying soft tissue must provide stable cutaneous coverage and obliteration of dead space. In cases where the fasciocutaneous flaps surrounding the defect are inadequate for closure, regional pedicled flaps or free flaps are recruited to achieve stable soft tissue coverage. PMID:23372458

    Handlebar hernias are abdominal wall hernias resulting from direct trauma to the anterior abdominal wall. They usually result at weak anatomic locations of the abdominal wall. Such traumatic hernias are rare, requiring a high index of suspicion for a clinical diagnosis. We report the case of a handlebar hernia resulting from an injury sustained during a vehicular injury, and discuss the management of such injuries. PMID:19568493

    Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall. An anorectal malformation consisting of a recto-vestibular fistula was also identified, and chest X-ray showed dextrocardia. The suggested treatment is repair of the defect before 1 year of age. Given that the anomalies described may accompany lateral abdominal wall hernia, it is important to diagnose and treat the associated defects.

    Blunt abdominal traumas are uncommonly encountered despite their high prevalence, and injuries to the organ like duodenum are relatively uncommon (occurring in only 3%-5% of abdominal injuries) because of its retroperitoneal location. Duodenal injury combined with gastric perforation from a single abdominal trauma impact is rarely heard. The aim of this case report is to present a rare case of blunt abdominal trauma with combined gastric and duodenal injuries. PMID:25738037

    Over the past twenty years, nonoperative management has increasingly been recommended for the care of patients with blunt abdominal trauma. Emergency laparotomy remains the rule in patients with hemodynamic instability or in those with peritonitis due to intestinal perforation. Surgical treatment of liver and splenic lesions tends to be more conservative. After assessment of the lesions by computed tomography, nonoperative management in intensive care unit is allowed in the majority of patients. PMID:9208689

    A 35-year-old man was delivered to the emergency room complaining of right flank pain because of blunt abdominal trauma sustained while playing baseball. Enhanced computed tomography (CT) revealed a right adrenal mass and fluid collection around the mass. We diagnosed the mass as pheochromocytoma by endocrinological examination and radioisotopical imaging test. After absorption of the hematoma three months after the injury, laparoscopic right adrenalectomy was performed. He had an uncomplicated postoperative course without supplementation of catecholamine. Pathological findings were compatible with pheochromocytoma. Eight months after the operation, he had no evidence of recurrence.

    Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended. PMID:26698210

    Traumatic abdominal wall hernia (TAWH) is a rare clinical entity in terms of aetiology. It occurs following a blunt abdominal injury with energy high enough to cause disruption of the musculoaponeurotic layer but not the elastic skin layer. It is often associated with underlying intra-abdominal injuries, which can be diagnosed either clinically or radiologically. We report a case of TAWH in a young man with associated large bowel transection, which remained undiagnosed in the preoperative period owing to its masked features. He was managed surgically, with no recurrence to date. Considering the high volume of blunt abdominal trauma cases that present to the accident and emergency department, only few cases of TAWH have been reported in the literature. Confusion still exists regarding the timing and mode of management of this condition. PMID:27241601

    The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

    Abdominal wall reconstruction is a complex and challenging surgical undertaking. While permanent prosthetic mesh is considered the gold standard for minimizing hernia recurrence, placement of synthetic mesh is sometimes imprudent due to contamination or risk of infection. Acellular dermal matrices (ADM) offer an exciting biologic alternative. This article provides a historical perspective on the evolution of complex ventral hernia repair leading up to and including the placement of ADM, an explanation of the biology of ADM as it relates to ventral hernia repair, and a description of the current indications, techniques, benefits, and shortcomings of its use in the abdominal wall.

    Abstract A liposarcoma is the most common type of soft tissue sarcoma, and most liposarcomas are malignant. The extremities are the most common site for liposarcomas. There are 5 histologic types of liposarcoma, as follows: well differentiated; myxoid; round cell; pleomorphic; and dedifferentiated. Myxoid liposarcomas (MLSs) represent a subgroup of liposarcomas. There has been no report of MLSs in the abdominal wall. We report a rare case of a MLS of a 43-year-old male who presented with tensile force on the abdominal wall. Computed tomography (CT) found a tumor in abdominal wall. There was no other abnormal symptom and the laboratory testing was also unusual. At last, the tumor was successfully excised, which was diagnosed MLSs in pathology. Following standard principles, after complete excision, the patient received radiotherapy. The patient was followed up for 8 month and no disease recurrence was identified. MLSs are rarely seen in the clinic, irrespective of the presenting signs, but also based on histologic features. The aim of this report was to present the differential diagnosis of an abdominal wall mass, and to remind us of MLSs. PMID:25526446

    Trauma is a leading cause of morbidity and mortality in childhood, and blunt trauma accounts for 80-90 % of abdominal injuries. The mechanism of trauma is quite similar to that of the adults, but there are important physiologic differences between children and adults in this field, such as the smaller blood vessels and the high vasoconstrictive response, leading to the spreading of a non-operative management. The early imaging of children undergoing a low-energy trauma can be performed by CEUS, a valuable diagnostic tool to demonstrate solid organ injuries with almost the same sensitivity of CT scans; nevertheless, as for as urinary tract injuries, MDCT remains still the technique of choice, because of its high sensitivity and accuracy, helping to discriminate between an intra-peritoneal form a retroperitoneal urinary leakage, requiring two different managements. The liver is the most common organ injured in blunt abdominal trauma followed by the spleen. Renal, pancreatic, and bowel injuries are quite rare. In this review we present various imaging findings of blunt abdominal trauma in children.

    Chest radiographs frequently underestimate the severity and extent of chest trauma and, in some cases, fail to detect the presence of injury. CT is more sensitive than chest radiography in the detection of pulmonary, pleural, and osseous abnormalities in the patient who has chest trauma. With the advent of multidetector CT (MDCT), high-quality multiplanar reformations are obtained easily and add to the diagnostic capabilities of MDCT. This article reviews the radiographic and CT findings of chest wall, pleural, and pulmonary injuries that are seen in the patient who has experienced blunt thoracic trauma.

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    Solitary fibrous tumors (SFTs) are uncommon neoplasms of mesenchymal origin that usually arise from the pleura. SFTs of the abdominal wall are extremely rare, and only 12 cases have been reported in the English language literature. This report presents a new case of SFT of the abdominal wall in a 74-year-old female. Positron emission tomography demonstrated the heterogeneous 18F-fluorodeoxyglucose uptake of the tumor (the maximum standardized uptake value was 2.8). Histologically, the mitotic count was 1 to 2/10 high-power fields. The patient is alive without recurrence at 10 months after undergoing a surgical excision. We discuss the clinicopathological features and differential diagnosis and present a review of the pertinent literature.

    After abdominal trauma, the lung is susceptible to secondary injury caused by acute neutrophil (PMN) sequestration and alveolar capillary membrane disruption. Adenosine is an endogenous anti-inflammatory metabolite that decreases PMN activation. AICAR ([5-amino-1-[beta-D-ribofuranosyl]imidazole-4-carboxamide]riboside) is the prototype of a novel class of anti-inflammatory drugs that increase endogenous adenosine. After trauma, AICAR administration has been shown to decrease secondary lung injury in models of hemorrhagic shock with delayed lipopolysaccharide challenge and pulmonary contusion. However, early suppression of PMN activation could worsen outcomes after penetrating abdominal trauma. We hypothesized that, after penetrating abdominal trauma, the ideal resuscitation strategy would involve early, short-lived suppression of PMN activation to minimize secondary lung injury, followed by later enhancement of PMN chemotaxis and phagocytosis [using granulocyte colony-stimulating factor (G-CSF)] to lessen late septic complications. G-CSF has not been shown to potentiate PMN mediated pulmonary reperfusion injury. Swine were subjected to cecal ligation/incision and hemorrhagic shock (trauma), followed by resuscitation with shed blood, crystalloid, and either G-CSF, a combination of G-CSF and AICAR, or 0.9% normal saline. At 72 h, bronchoalveolar lavage (BAL) leukocyte counts and protein concentration were determined, and lung tissue analysed for myeloperoxidase (MPO, a measure of PMN infiltration) and microscopic pathology. Analysis of BALs revealed a significant increase protein concentrations and in white blood cell and PMN infiltration (P< 0.05) following trauma. These acute changes were not exacerbated by G-CSF, but were reversed by combined AICAR + G-CSF, which implicates a physiologic role for adenosine. This suggests that combination therapy may have beneficial effects on the lung after trauma.

    The aim of this study is to determine the magnitude of change in spleen volume on CT in subjects sustaining blunt abdominal trauma without hemorrhage relative to patients without disease and how the spleen volumes are distributed. Sixty-seven subjects with blunt abdominal trauma and 101 control subjects were included in this retrospective single-center, IRB-approved, and HIPAA-compliant study. Patients with an injured spleen were excluded. Using a semiautomatic segmentation program, two readers computed spleen volumes from CT. Spleen volume distribution in male and female trauma and control cohorts were compared nonparametrically. Spleen volume plotted against height, weight, and age were analyzed by linear regression. The number of females and males are, respectively, 35 and 32 in trauma subjects and 69 and 32 among controls. Female trauma patients (49.6 years) were older than males (39.8 years) (p = 0.02). Distributions of spleen volume were not normal, skewed above their means, requiring a nonparametric comparison. Spleen volumes in trauma patients were smaller than those in controls with medians of 230 vs 294 mL in males(p < 0.006) and 163 vs 191 mL in females(p < 0.04). Spleen volume correlated positively with weight in females and with height in male controls, and negatively with age in male controls (p < 0.01). Variation in reproducibility and repeatability was acceptable at 1.5 and 4.9 %, respectively. Reader variation was 1.7 and 4.6 % for readers 1 and 2, respectively. The mean spleen volume in controls was 245 mL, the largest ever reported. Spleen volume decreases in response to blunt abdominal trauma. Spleen volumes are not normally distributed. Our population has the largest spleen volume reported in the literature, perhaps a consequence of the obesity epidemic. PMID:27166964

    2016-01-01

    Background: A new closure technique is introduced, which uses strips of macroporous polypropylene mesh as a suture for closure of abdominal wall defects due to failures of standard sutures and difficulties with planar meshes. Methods: Strips of macroporous polypropylene mesh of 2 cm width were passed through the abdominal wall and tied as simple interrupted sutures. The surgical technique and surgical outcomes are presented. Results: One hundred and seven patients underwent a mesh sutured abdominal wall closure. Seventy-six patients had preoperative hernias, and the mean hernia width by CT scan for those with scans was 9.1 cm. Forty-nine surgical fields were clean-contaminated, contaminated, or dirty. Five patients had infections within the first 30 days. Only one knot was removed as an office procedure. Mean follow-up at 234 days revealed 4 recurrent hernias. Conclusions: Mesh sutured repairs reliably appose tissue under tension using concepts of force distribution and resistance to suture pull-through. The technique reduces the amount of foreign material required in comparison to sheet meshes, and avoids the shortcomings of monofilament sutures. Mesh sutured closures seem to be tolerant of bacterial contamination with low hernia recurrence rates and have replaced our routine use of mesh sheets and bioprosthetic grafts. PMID:27757361

    Hepatic echinococcosis is endemic in Israel, with about 90 new cases diagnosed each year. Although many are asymptomatic for years, 40% develop complications. We describe a man of 37 and women aged 22 and 35, respectively, in whom rupture of an echinococcal cyst followed minimal, blunt abdominal trauma. In each patient the rupture led to complications consisting of massive intra-abdominal bleeding in 1, diffuse peritonitis in another and cystocutaneous fistula with ureteral obstruction due to reactive retroperitoneal fibrosis in the third. All 3 underwent surgery to resolve the immediate complication, with no mortality. A striking feature was the disproportion between the stormy clinical presentation and the relatively innocent nature of the trauma. In only 1 of our cases was the correct preoperative diagnosis made, which in this condition depends primarily on a high index of suspicion.

    A surgeon has many options available to aid in the closure of abdominal wall defects in the elective setting. In the emergent setting, active infection or contamination increases the likelihood of infection of permanent prosthetic material and limits the surgical options. In such settings, we have used absorbable mesh (Dexon) as an adjunct to fascial closure until the acute complications resolve. To evaluate the effectiveness of this technique, we reviewed the outcome of such closures in 26 critically ill patients. Between July 1987 and June 1993, 26 patients were identified who had placement of absorbable mesh as part of an emergent laparotomy at a major urban trauma center. Through a retrospective chart review, the incidence of complications and outcome of the closure were tabulated. Seven patients were initially operated on for trauma. Two of the patients had mesh placement at their initial procedure secondary to fascial loss from trauma. The remainder of the patients hd mesh placement during a subsequent laparotomy for complications related to their initial procedure. Indications for these laparotomies included combinations of wound dehiscence, intra-abdominal abscess, anastomotic disruption, and perforation. Mesh placement in patients with intra-abdominal infection created effectively open abdominal wounds that allowed continued abdominal drainage, but required extensive wound care. Despite the absorbable nature of the mesh and often prolonged hospital stay in these ill patients, none of them required reoperation for dehiscence, recurrence of intra-abdominal abscess, or infection of the mesh.(ABSTRACT TRUNCATED AT 250 WORDS)

    Intra-abdominal hypertension (IAH) is an important contributor to early organ dysfunction among patients with trauma and sepsis. However, the impact of increased intra-abdominal pressure (IAP) among pediatric, pregnant, non-septic medical patients, and those with severe acute pancreatitis (SAP), obesity, and burns has been studied less extensively. The aim of this review is to outline the pathophysiologic implications and treatment options for IAH and abdominal compartment syndrome (ACS) for the above patient populations. We searched MEDLINE and PubMed to identify relevant studies. There is an increasing awareness of IAH in general medicine. The incidence of IAH and, to a lesser extent, ACS is high among patients with SAP. IAH should always be suspected and IAP measured routinely. In children, normal IAP in mechanically ventilated patients is approximately 7 ± 3 mm Hg. As an IAP of 10-15 mm Hg has been associated with organ damage in children, an IAP greater than 10 mm Hg should be considered IAH in these patients. Moreover, as ACS may occur in children at an IAP lower than 20 mm Hg, any elevation in IAP higher than 10 mm Hg associated with new organ dysfunction should be considered ACS in children until proven otherwise. Monitor IAP trends and be aware that specific interventions may need to be instituted at lower IAP than the current ACS definitions accommodate. Finally, IAH and ACS can occur both in abdominal trauma and extra-abdominal trauma patients. Early mechanical hemorrhage control and the avoidance of excessive fluid resuscitation are key elements in preventing IAH in trauma patients. IAH and ACS have been associated with many conditions beyond the general ICU patient. In adults and in children, the focus should be on the early recognition of IAH and the prevention of ACS. Patients at risk for IAH should be identified early during their treatment (with a low threshold to initiate IAP monitoring). Appropriate actions should be taken when IAP increases

    A 28-year-old man was admitted to the emergency department with lumbar pain owing to a motorbike accident. On clinical examination, abdominal tenderness, pelvic and left cruris pains were present. Erythrocytes, leucocytes and protein was found to be positive in urine analysis. Abdominal computed tomography with intravenous contrast solution showed contrast enhancement in 80% of right kidney, and 30% of left kidney; some intra-abdominal free fluid was also seen. Conservative management was planned for bilateral renal infarction. Urine output was 1.1 L per day. He was discharged on the seventh day of the hospital stay. The patient had not got any problems on the sixth month follow-up. Urine output is a very important parameter for multiple trauma patients. Any decrease in urine output may not be seen inspite of the presence of bilateral renal damage as in the case of the patient, and this situation does not allow ruling out renal injury completely. Hence, emergency physician should still be careful about the risk of renal injury.

    The aim of this study was to investigate features of abdominal earthquake-related crush traumas in comparison with non-earthquake injury. A cross sectional survey was conducted with 51 survivors with abdominal crush injury in the 2008 Sichuan earthquake, and 41 with abdominal non-earthquake injury, undergoing non-enhanced computed tomography (CT) scans, serving as earthquake trauma and control group, respectively. Data were analyzed between groups focusing on CT appearance. We found that injury of abdominal-wall soft tissue and fractures of lumbar vertebrae were more common in earthquake trauma group than in control group (28 vs 13 victims, and 24 vs 9, respectively; all P < 0.05); and fractures were predominantly in transverse process of 1-2 vertebrae among L1-3 vertebrae. Retroperitoneal injury in the kidney occurred more frequently in earthquake trauma group than in control group (29 vs 14 victims, P < 0.05). Abdominal injury in combination with thoracic and pelvic injury occurred more frequently in earthquake trauma group than in control group (43 vs 29 victims, P < 0.05). In conclusion, abdominal earthquake-related crush injury might be characteristic of high incidence in injury of abdominal-wall soft tissue, fractures of lumbar vertebrae in transverse process of 1-2 vertebrae among L1-3 vertebrae, retroperitoneal injury in the kidney, and in combination with injury in the thorax and pelvis.

    Background: Abdominal wall, one of the most commonly transplanted composite tissues, is less researched and lacking animal models. Its clinical necessities were emphasized in multiple case series to reconstruct large abdominal defects. Previous animal models have only studied components of the abdominal wall transplant. We describe findings from a new model that more likely reflect clinical transplantation. Methods: Full-thickness hemiabdominal wall flap was procured from Brown Norway (BN) rats and transplanted to an orthotopic defect on Lewis rats. Three groups were studied: group 1: Lewis to Lewis syngeneic; group 2: BN to Lewis control; and group 3: BN to Lewis with postoperative cyclosporine. Vascular imaging and cross vessel section were performed along with full-thickness abdominal wall. Immune cell profiling with flow cytometry at different time points was studied in all groups. Results: Syngeneic group had no rejection. Control group consistently showed rejection around postoperative day 6. With cyclosporine treatment, however, transplant and recipient tissue integration was observed. Flow cytometry revealed that innate immunity is responsible for the initial inflammatory events following abdominal wall engraftment. Adaptive immunity cells, specifically interferon-γ-producing T helper (Th) 1 and interleukin-17-producing Th17 cells, dramatically and positively correlate with rejection progression of abdominal wall transplants. Conclusions: Technical, histological, and immunological aspects of a new rat model are described. These results give clues to what occurs in human abdominal wall transplantation. In addition, Th1, a proinflammatory cell, was found to be a potential biomarker for allograft rejection. PMID:25289329

    The pregnant abdominal trauma patient presents a unique diagnostic challenge. This study aimed to evaluate the accuracy of abdominal sonography for the detection of clinically important injuries in pregnant abdominal trauma patients. A retrospective review was performed of a trauma center database from 2001 to 2011. Medical records were reviewed to determine initial abdominal imaging test results and clinical course. Sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for detection of traumatic injury were calculated. Of 19,128 patients with suspected abdominal trauma, 385 (2 %) were pregnant. Of these, 372 (97 %) received ultrasound as the initial abdominal imaging test. All 13 pregnant patients who did not receive ultrasound received abdominal CT. Seven pregnant patients underwent both ultrasound and CT. Seven ultrasound examinations were positive, leading to one therapeutic Cesarean section and one laparotomy. One ultrasound was considered false positive (no injury was seen on subsequent CT). There were 365 negative ultrasound examinations. Of these, 364 were true negative (no abdominal injury subsequently found). One ultrasound was considered false negative (a large fetal subchorionic hemorrhage seen on subsequent dedicated obstetrical ultrasound). Sensitivity and positive predictive value were 85.7 %. Specificity and negative predictive value were 99.7 %. Abdominal sonography is an effective and sufficient imaging examination in pregnant abdominal trauma patients. When performed as part of the initial assessment using an abbreviated trauma protocol with brief modifications for pregnancy, ultrasound minimizes diagnostic delay, obviates radiation risk, and provides high sensitivity for injury in the pregnant population.

    Traumatic abdominal wall hernia (TAWH) from high speed mechanism is a unique finding in adult trauma, and exceedingly rare in pediatrics. The majority of reports are of low-speed "handlebar" hernias associated with direct injury by bicycle handlebars. We report a series of three pediatric patients in motor vehicle collisions (MVC) who experienced TAWH by lap-belt and associated intra-abdominal injuries necessitating immediate operative intervention. Different operative approaches were used in each case to manage the varying types of disruptions. This adds to the pediatric literature the largest series of its kind.

    Baseline ultrasound is essential in the early assessment of patients with a huge haemoperitoneum undergoing an immediate abdominal surgery; nevertheless, even with a highly experienced operator, it is not sufficient to exclude parenchymal injuries. More recently, a new ultrasound technique using second generation contrast agents, named contrast-enhanced ultrasound (CEUS) has been developed. This technique allows all the vascular phase to be performed in real time, increasing ultrasound capability to detect parenchymal injuries, enhancing some qualitative findings, such as lesion extension, margins and its relationship with capsule and vessels. CEUS has been demonstrated to be almost as sensitive as contrast-enhanced CT in the detection of traumatic injuries in patients with low-energy isolated abdominal trauma, with levels of sensitivity and specificity up to 95%. Several studies demonstrated its ability to detect lesions occurring in the liver, spleen, pancreas and kidneys and also to recognize active bleeding as hyperechoic bands appearing as round or oval spots of variable size. Its role seems to be really relevant in paediatric patients, thus avoiding a routine exposure to ionizing radiation. Nevertheless, CEUS is strongly operator dependent, and it has some limitations, such as the cost of contrast media, lack of panoramicity, the difficulty to explore some deep regions and the poor ability to detect injuries to the urinary tract. On the other hand, it is timesaving, and it has several advantages, such as its portability, the safety of contrast agent, the lack to ionizing radiation exposure and therefore its repeatability, which allows follow-up of those traumas managed conservatively, especially in cases of fertile females and paediatric patients.

    The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity. PMID:27293982

    Surgeons occasionally encounter a patient with a gastric cancer invading an adjacent organ, such as the pancreas, liver, or transverse colon. Although there is no established guideline for treatment of invasive gastric cancer, combined resection with radical gastrectomy is conventionally performed for curative purposes. We recently treated a patient with a large gastric cancer invading the abdominal wall, which was initially diagnosed as a simple abdominal wall abscess. Computed tomography showed that an abscess had formed adjacent to the greater curvature of the stomach. During surgery, we made an incision on the abdominal wall to drain the abscess, and performed curative total gastrectomy with partial excision of the involved abdominal wall. The patient received intensive treatment and wound management postoperatively with no surgery-related adverse events. However, the patient could not receive adjuvant chemotherapy and expired on the 82nd postoperative day. PMID:26468420

    Ultrasonography (US) is becoming increasingly utilized in the United States for the evaluation of blunt abdominal trauma (BAT). The objective of this study was to assess the cost impact of utilizing US in the evaluation of patients with BAT in a major trauma center. All patients sustaining BAT during a 6-month period before US was used at our institution (Jan-Jun 1993) were compared to BAT patients from a recent period in which US has been utilized (Jan-Jun 1995). The numbers of US, computed tomography (CT), and diagnostic peritoneal lavage (DPL) were tabulated for each group. Financial cost for each of these procedures as determined by our finance department were as follows: US $96, CT $494, DPL $137. These numbers are representative of actual hospital expenditures exclusive of physician fees as calculated in 1994 U.S. dollars. Cost analysis was performed with t test and chi squared test, and significance was defined as P < 0.05. There were 890 BAT admissions in the 1993 study period and 1033 admissions in the 1995 study period. During the 1993 period, 642 procedures were performed on the 890 patients to evaluate the abdomen: 0 US, 466 CT, and 176 DPL (see table) [table: see text]. This compares to 801 procedures on the 1,033 patients in 1995: 552 US, 228 CT, and 21 DPL. Total cost was $254,316 for the 1993 group and $168,501 for the 1995 group. Extrapolated to a 1-year period, a significant (P < 0.05) cost savings of $171,630 would be realized. Cost per patient evaluated was significantly reduced from $285.75 in 1993 to $163.12 in 1995 (P < 0.05). This represents a 43 per cent reduction in per patient expenditure for evaluating the abdomen. By effectively utilizing ultrasonography in the evaluation of patients with blunt abdominal trauma, a significant cost savings can be realized. This effect results chiefly from an eight-fold reduction in the use of DPL, and a two-fold reduction in the use of CT. PMID:11603547

    Introduction Intra-abdominal hemorrhage due to blunt abdominal trauma is a major cause of trauma-related mortality. Therefore, any action taken for facilitating the diagnosis of intra-abdominal hemorrhage could save the lives of patients more effectively. The aim of this study was to determine the accuracy of focused assessment with sonography for trauma (FAST) performed by emergency physicians. Methods In this cross-sectional study from February 2011 to January 2012 at 7th Tir Hospital in Tehran (Iran), 120 patients with abdominal blunt trauma were chosen and evaluated for abdominal fluid. FAST sonography was performed for all the subjects by emergency residents and radiologists while they were blind to the other tests. Abdominal CTs, which is the gold standard, were done for all of the cases. SPSS 20.0 was used to analyze the results. Results During the study, 120 patients with abdominal blunt trauma were evaluated; the mean age of the patients was 33.0 ± 16.6 and the gender ratio was 3/1 (M/F). The results of FAST sonography by emergency physicians showed free fluid in the abdomen or pelvic spaces in 33 patients (27.5%), but this was not observed by the results of CT scans of six patients; sensitivity and specificity were 93.1 and 93.4%, respectively. As for tests performed by radiology residents, sensitivity was a bit higher (96.5%) with lower specificity (92.3%). Conclusion The results suggested that emergency physicians can use ultrasonography as a safe and reliable method in evaluating blunt abdominal trauma. PMID:27790349

    Introduction Desmoid tumors are rare lesions without any metastatic potential but a strong tendency to invade locally and to recur. These tumors are associated with women of fertile age, especially during and after pregnancy. Case presentation The case of a desmoid tumor of the anterior abdominal wall in a 40-year-old Caucasian man with no relevant family history is presented, describing its appearance on computed tomography and ultrasonography. The patient, who presented with a painless mass in the left anterolateral abdomen, had a history of previous urgent abdominal surgery after a shotgun injury two years earlier. Radical resection of the affected abdominal wall musculature was performed, and the defect was reconstructed with polypropylene mesh. Conclusion The diagnosis of desmoid tumor should be strongly considered even in male patients with an abdominal mass and a history of previous abdominal surgery. The goal of its treatment is complete tumor excision and avoidance of the development of complications such as hernia. PMID:21787413

    As hernias and abdominal wall defects have a variety of etiologies each with its own complications and comorbidities in various constellations, efficient treatment requires patient-oriented management. There is no recommended standard treatment and the very different clinical pictures demand an individualized interdisciplinary approach. Particularly in the case of complicated hernias, the planning of the operation should focus on the problems posed by the individual patient. Treatment mainly depends on the etiology of the hernia, immediate or long-term complications and the efficiency of individual repair techniques. Abdominal wall repair for recurrent herniation requires direct closure of the fascia generally using the sublay technique with a lightweight mesh. It is still unclear whether persistent inflammation, mesh dislocation, fistula formation or other long-term complications are due to certain materials or to the surgical technique. With mesh infections it has been shown to be advantageous to remove a polytetrafluoroethylene (PTFE) mesh, while the combination of systemic and local treatment appears to suffice for a polypropylene or polyester mesh. Heavier meshes in the sublay position or plastic reconstruction with autologous tissue are indicated as substitutes for the abdominal wall for giant hernias, repeated recurrences and large abdominal wall defects. A laparostoma is increasingly more often created to treat septic intra-abdominal processes but is very often responsible for a complicated hernia. If primary repair of the abdominal wall is not an option, resorbable material or split skin is used for coverage under the auspices of a planned hernia repair.

    The spleen is the most commonly injured abdominal organ in children who sustain blunt abdominal trauma, and pediatric splenic injury may result from minor mechanisms of injury, including sports participation. We present 2 cases of splenic injury in soccer goalies because of blunt abdominal trauma sustained during game play. Although abdominal organ injuries are uncommon in soccer, emergency medicine and primary care physicians must be aware of the possibility. A high index of suspicion and careful physical examination are key in making the diagnosis.

    Background: The incidence of abdominal trauma is still underreported from the Arab Middle-East. We aimed to evaluate the incidence, causes, clinical presentation, and outcome of the abdominal trauma patients in a newly established trauma center. Materials and Methods: A retrospective analysis was conducted at the only level I trauma center in Qatar for the patients admitted with abdominal trauma (2008-2011). Patients demographics, mechanism of injury, pattern of organ injuries, associated extra-abdominal injuries, Injury Severity Score (ISS), Abbreviated Injury Scale, complications, length of Intensive Care Unit, and hospital stay, and mortality were reviewed. Results: A total of 6888 trauma patients were admitted to the hospital, of which 1036 (15%) had abdominal trauma. The mean age was 30.6 ± 13 years and the majority was males (93%). Road traffic accidents (61%) were the most frequent mechanism of injury followed by fall from height (25%) and fall of heavy object (7%). The mean ISS was 17.9 ± 10. Liver (36%), spleen (32%) and kidney (18%) were most common injured organs. The common associated extra-abdominal injuries included chest (35%), musculoskeletal (32%), and head injury (24%). Wound infection (3.8%), pneumonia (3%), and urinary tract infection (1.4%) were the frequently observed complications. The overall mortality was 8.3% and late mortality was observed in 2.3% cases mainly due to severe head injury and sepsis. The predictors of mortality were head injury, ISS, need for blood transfusion, and serum lactate. Conclusion: Abdominal trauma is a frequent diagnosis in multiple trauma and the presence of extra-abdominal injuries and sepsis has a significant impact on the outcome. PMID:26604524

    An abdominal aortic aneurysm is a pathological dilation of the abdominal aorta, which carries a high mortality rate if ruptured. The most commonly used surrogate marker of rupture risk is the maximal transverse diameter of the aneurysm. More recent studies suggest that wall stress from models of patient-specific aneurysm geometries extracted, for instance, from computed tomography images may be a more accurate predictor of rupture risk and an important factor in AAA size progression. However, quantification of wall stress is typically computationally intensive and time-consuming, mainly due to the nonlinear mechanical behavior of the abdominal aortic aneurysm walls. These difficulties have limited the potential of computational models in clinical practice. To facilitate computation of wall stresses, we propose to use a linear approach that ensures equilibrium of wall stresses in the aneurysms. This proposed linear model approach is easy to implement and eliminates the burden of nonlinear computations. To assess the accuracy of our proposed approach to compute wall stresses, results from idealized and patient-specific model simulations were compared to those obtained using conventional approaches and to those of a hypothetical, reference abdominal aortic aneurysm model. For the reference model, wall mechanical properties and the initial unloaded and unstressed configuration were assumed to be known, and the resulting wall stresses were used as reference for comparison. Our proposed linear approach accurately approximates wall stresses for varying model geometries and wall material properties. Our findings suggest that the proposed linear approach could be used as an effective, efficient, easy-to-use clinical tool to estimate patient-specific wall stresses. PMID:25007052

    We sought to use the National Trauma Databank to determine the demographics, injury distribution, associated abdominal injuries, and outcomes of those patients who are restrained versus unrestrained. All victims of motor vehicle collisions (MVCs) were identified from the National Trauma Databank and stratified into subpopulations depending on the use of seat belts. A total of 150,161 MVC victims were included in this study, 72,394 (48%) were belted. Young, male passengers were the least likely to be wearing a seat belt. Restrained victims were less likely to have severe injury as measured by Injury Severity Score and Abbreviated Injury Score. Restrained victims were also less likely to suffer solid organ injuries (9.7% vs 12%, P < 0.001), but more likely to have hollow viscous injuries (1.9% vs 1.3%, P < 0.001). The hospital and intensive care unit length of stay were significantly shorter in belted victims with adjusted mean difference: -1.36 (-1.45, -1.27) and -0.96 (-1.02, -0.90), respectively. Seat belt use was associated with a significantly lower crude mortality than unrestrained victims (1.9% vs 3.3%, P < 0.001), and after adjusting for differences in age, gender, position in vehicle, and deployment of air bags, the protective effect remained (adjusted odds ratio for mortality 0.50, 95% confidence interval 0.47, 0.54). In conclusion, MVC victims wearing seat belts have a significant reduction in the severity of injuries in all body areas, lower mortality, a shorter hospital stay, and decreased length of stay in the intensive care unit. The nature of abdominal injuries, however, was significantly different, with a higher incidence of hollow viscous injury in those wearing seat belts.

    Background The goal of conservative management (CM) of penetrating abdominal trauma is to avoid nontherapeutic laparotomies while identifying injuries early. Factors that may predict CM failure are not well established, and the experience of CM has not been well described in the Canadian context. Methods We searched a Canadian level 1 trauma centre database for all penetrating abdominal traumas treated between 2004 and 2014. Hemodynamically stable patients without peritonitis and without clear indications for immediate surgery were considered potential candidates for CM, and were included in the study. We compared those who were managed with CM with those who underwent immediate operative management (OM). Outcomes included mortality and length of stay (LOS). Further analysis was performed to identify predictors of CM failure. Results A total of 72 patients with penetrating abdominal trauma were classified as potential candidates for CM. Ten patients were managed with OM, and 62 with CM, with 9 (14.5%) ultimately failing CM and requiring laparotomy. The OM and CM groups were similar in terms of age, sex, injury severity, mechanism and number of injuries. There were no deaths in either group. The LOS in the intensive care (ICU)/trauma unit was 4.8 ± 3.2 days in the OM group and 2.9 ± 2.6 days in the CM group (p = 0.039). The only predictor for CM failure was intra-abdominal fluid on computed tomography (CT) scan (odds ratio 5.3, 95% confidence interval 1.01–28.19). Conclusion In select patients with penetrating abdominal trauma, CM is safe and results in a reduced LOS in the ICU/trauma unit of 1.9 days. Fluid on CT scan is a predictor for failure.

    INTRODUCTION Acute appendicitis commonly presents as an acute abdomen. Cases of acute appendicitis caused by blunt abdominal trauma are rare. We present a systematic review of appendicitis following blunt abdominal trauma. The aim of this review was to collate and report the clinical presentations and experience of such cases. SUBJECTS AND METHODS A literature review was performed using PubMed, Embase and Medline and the keywords ‘appendicitis’, ‘abdominal’ and ‘trauma’. RESULTS The initial search returned 381 papers, of which 17 articles were included. We found 28 cases of acute appendicitis secondary to blunt abdominal trauma reported in the literature between 1991 and 2009. Mechanisms of injury included road-traffic accidents, falls, assaults and accidents. Presenting symptoms invariably included abdominal pain, but also nausea, vomiting and anorexia. Only 12 patients had computed tomography scans and 10 patients had ultrasonography. All reported treatment was surgical and positive for appendicitis. CONCLUSIONS Although rare, the diagnosis of acute appendicitis must be considered following direct abdominal trauma especially if the patient complains of abdominal right lower quadrant pain, nausea and anorexia. Haemodynamically stable patients who present shortly after blunt abdominal trauma with right lower quadrant pain and tenderness should undergo urgent imaging with a plan to proceed to appendicectomy if the imaging suggested an inflammatory process within the right iliac fossa.

    This study describes the treatment of two patients with recurrent, infected abdominal wall defects using bilateral delayed and tunnelled pedicled tensor fascia lata (TFL) myofascial flaps. TFL flaps were elevated and delayed for 4 weeks in both cases. In the second case, Parietex Composite mesh was positioned underneath the TFL flap and allowed to incorporate. After a delay of 4 weeks, the flaps were harvested and tunnelled subcutaneously to repair the abdominal wall defect. Both patients have stable repairs but had donor site seromas requiring drainage. Cadaver dissection was also performed to identify structures related to TFL flap harvest. We identified a variant of lateral femoral cutaneous nerve that traversed the TFL flap, necessitating meticulous dissection during surgery. In summary, we describe a new technique of incorporating mesh into the TFL prior to flap harvest for reconstruction of complex abdominal wall. PMID:22707661

    Background The survival rate of newborns with severe congenital abdominal wall defects has increased. After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall. Methods We performed a chart review of five cases treated in our institution. Results Five patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case. Conclusions Patients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

    The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.

    The typical presentation of intussusception includes intermittent severe abdominal pain, vomiting, rectal bleeding, and the presence of an abdominal mass. We present a case of intussusception after abdominal blunt trauma along with a literature review. A 4-year-old girl was admitted to the emergency department after a bicycle accident. She complained of progressively worsening abdominal pain, but there was no vomiting, fever, bloody stool, or abdominal mass. She was finally diagnosed with traumatic intussusception by ultrasonography and treated with air reduction. Because the typical symptoms are unusual in traumatic intussusception, close attention must be paid to avoid a delayed diagnosis. PMID:27752618

    "Open abdomen" is a strategy used to avoid or treat abdominal compartment syndrome. It has reduced mortality both in trauma and non-trauma abdominal catastrophes but also has created a challenging clinical problem. Traditionally, open abdomen is closed in two phases; primarily with a free skin graft and later with a flap reconstruction. A modern trend is to close the abdomen within the initial hospitalization. This requires multi-professional co-operation. Temporary abdominal closure methods, e.g. negative pressure wound therapy alone or combined with mesh-mediated traction, have been developed to facilitate direct fascial closure. Components separation technique, mesh reinforcement or bridging of the fascial defect with mesh and perforator saving skin undermining can be utilized in the final closure if needed. These techniques can be combined. Choice of the treatment depends on the condition of the patient and size of the fascia and skin defect, and the state of the abdominal contents. In this paper we review the literature on the closure of an open abdomen and present the policy used in our institution in the open abdomen situations.

    Gastrointestinal hollow viscus injury after blunt chest and abdominal trauma is uncommon and complicates 0.6%-1.2% of all cases of trauma. Early recognition of such injuries significantly decreases morbidity and mortality. Since physical examination is not accurate in detecting such injuries, contrast-enhanced computed tomography has been the mainstay for diagnosis in many emergency departments. This pictorial essay aims to review the incidence, mechanisms, and signs of gastrointestinal hollow viscus injuries in the setting of blunt chest and abdominal trauma.

    Transversus abdominal plane (TAP) block is a known and useful technique, widely used for postoperative pain management of abdominal wall incisions. During the past years, and following the expansion of ultrasound guided techniques, its use has even gained more adepts. It is usually used as an adjuvant technique, primarily in order to control postoperative pain and reduce opioids consumption. We report the case of an 82 years old patient admitted for drainage of a postoperative abdominal wall hematoma after correction of a McBurney incisional hernia. The corrective surgery had gone on without incident, under general anesthesia with laryngeal mask. Two weeks later, the patient came back to our emergency department with a clear hematoma of the abdominal wall. Surgery was decided. A sole local anesthetic technique was achieved, using a TAP block. The block was performed under ultrasound guidance, using a subcostal approach. The surgery went on without complications. Therefore, TAP block offers a hemodynamic stability, appropriate intra-operative anesthesia and post-surgical analgesia of the abdominal wall.

    A 78 -year-old man with rectal cancer underwent abdominoperineal resection of the rectum. In the postoperative period, the patient experienced wound infection, leading to an abdominal wall hernia. Two years following surgery, a rise in the serum CEA level was seen. A metastatic tumor was detected in the right lung on chest CT. VATS right lung inferior lobe segmental resection was performed. After lobectomy, the serum CEA level continued to increase. Another metastatic tumor was detected in the right lung on chest CT. Chemotherapy with capecitabine, oxaliplatin, and bevacizumab was commenced. The erosive part of the abdominal wall scar hernia extended during the nine weeks of chemotherapy. The chemotherapy was then discontinued. In the follow-up CT scan, a right pleural recurrence, local recurrence in the pelvis, and a liver metastasis were detected. Chemotherapy was re-introduced 3 years after surgery. The erosive part of the abdominal wall hernia again began to spread with chemotherapy recommencement. Four months after restarting chemotherapy, the hernia ruptured, with a loop of the small intestine protruding out of it. The patient covered this with a sheet of vinyl and was taken by the ambulance to our hospital. The erosive part of the abdominal wall hernia had split by 10 cm, and a loop of the small intestine was protruding. As ischemia of the small intestine was not observed, we replaced it into the abdominal cavity, and performed a temporary suture repair of the hernia sac. Following this, bevacizumab was discontinued, and the erosive part reduced. We performed a radical operation for abdominal wall scar hernia repair 11 weeks after the discontinuation of bevacizumab.

    The use of closed suction drains in the abdominal wall is a common practice in abdominal wall reconstruction (AWR) operations. Drains can be a conduit for bacteria and can cause pain and discomfort for patients after surgery. A single hernia program has implemented the principles of clinical quality improvement in an attempt to improve outcomes for hernia patients. An attempt at a process improvement was implemented to eliminate the use of drains in AWR by adapting the technique. A total of 102 patients undergoing AWR were included between 8/11 and 9/15 (49 months). Compared with the group before the attempt at eliminating the use of abdominal wall drains (8/11-9/13), the group of patients after the implementation of the attempted process improvement (9/13-9/15) had less wound and pulmonary complications, a shorter hospital stay, less time in the postanesthesia care unit, and less opioid use in the postanesthesia care unit as well as for the entire hospital stay. In this group of AWR patients, an attempt at process improvement that eliminated the use of drains led to improved outcomes. Abdominal wall drains may be able to be safely eliminated with appropriate technique adaptation for AWR. PMID:27657586

While a positive FAST in a hypotensive trauma patient usually indicates hemoperitoneum, this case illustrates that the timing of the FAST examination relative to the injury, as well as clinical evolution including the volume of fluid resuscitation, need to be considered when interpreting the results of serial and/or late FAST examinations.

    Introduction Traumatic diaphragmatic rupture (TDR) occurs in 0–5% of patients with major blunt thoraco-abdominal trauma, in most of them on the left side, and an early correct diagnosis is made in less than half of the cases (Meyers and McCabe, 1993; Ball et al., 1982). Presentation of the case We report a case of a forty-eight years old man who had a pericardio-diaphragmatic rupture after a high-velocity blunt abdominal trauma that was diagnosed and treated successfully. Discussion Pericardio-diaphragmatic rupture (PDR) is an uncommon problem that poses a diagnostic challenge to surgeons. The incidence of PDR is between 0.2% and 3.3% of cases with TDR (Sharma, 1999 [3]). Conclusion PDR should be suspected in any patient with high velocity thoraco-abdominal trauma. Early diagnosis is essential and needs a high index of suspicion. Early Management is important in decreasing morbidity and mortality. PMID:26773877

    The management of traumatic abdominal wall hernias is controversial. We performed a MEDLINE search and report a personal series of 10 patients. Cases were classified according to the cause of injury. Fifty-six percent were caused by car accidents and 14% by bicycle accidents. Diagnosis was clinical in 22% and surgical in 13% and intra-abdominal lesions were found in 67%. Treatment was delayed in 12%. In our series, 55% were lumbar hernias due to traffic accidents and all were associated with pelvic fracture. Treatment was delayed in 50%, including laparoscopic surgery with good results. In conclusion, traumatic hernias due to road traffic accidents are frequently associated with intra-abdominal lesions. The diagnostic technique of choice is computed tomography and delayed surgery (laparoscopy) is an effective option. PMID:18021624

    Introduction: Focused assessment with sonography for trauma (FAST) is a highly effective first screening tool for initial classification of abdominal trauma patients. The present study was designed to evaluate the outcome of patients with blunt abdominal trauma and positive FAST findings. Methods: The present prospective cross-sectional study was done on patients over 7 years old with normal abdominal examination, positive FAST findings, and available abdominopelvic computed tomography (CT) scan findings. The frequency of need for laparotomy as well as its probable risk factors were calculated. Results: 180 patients were enrolled (mean age: 28.0 ± 11.5 years; 76.7% male). FAST findings were confirmed by abdominopelvic CT scan in only 124 (68.9%) cases. Finally, 12 (6.6%) patients needed laparotomy. Mean age of those in need of laparotomy was significantly higher than others (36.75 ± 11.37 versus 27.34 ± 11.37, p = 0.006). Higher grading of spleen (p = 0.001) and hepatic (p = 0.038) ruptures increased the probability of need for laparotomy. Conclusion: 68.9% of the positive FAST findings in patients with blunt abdominal trauma and stable hemodynamics was confirmed by abdominopelvic CT scan and only 6.6% needed laparotomy. Simultaneous presence of free fluid and air in the abdominal area, old age, and higher grading o solid organ injuries were factors that had a significant correlation with need for laparotomy.

    Abdominal wall endometriosis is rare and its diagnosis is difficult. However, the consequences may be serious, like recurrences or even malignant transformation. We report a rarer case of asymptomatic abdominal wall endometrioma, accidentally found during a surgical procedure for a second cesarean section, in a 39-years old patient, without any relevant history of endometriosis. The tumor was subcutaneous, 3/3 cm in size, located in the left angle of the incision from the 15 years previously performed cesarean section and freely mobile in relation with the skin and the fascia. It was excised, with clear margins (to prevent recurrences), during the procedure. The patient was discharged after five days. The postoperative period and the follow-up at one and three months were uneventful. The pathological examination clarified the diagnosis by revealing an endometrioma with decidual reaction. Such a condition may be, therefore, evoked before an abdominal wall tumor, even without specific symptoms, even in a 39-years old woman and longtime after the possible causal surgery. Pathological examination remains the ultimate diagnostic tool. Relevant prophylactic attitude at the end of the cesarean section may be considered.

    Blunt injury of the abdominal aorta is highly fatal. We present an unusual case of an osteophyte impaling the abdominal aorta treated by endovascular repair. A 77-year-old man sustained a thoracolumbar fracture-dislocation with posterior aortic rupture between his celiac and superior mesenteric artery origins. His aortic injury was treated with a stent graft, excluding the celiac origin. He was dismissed on postoperative day 6. At 6 months, he had returned to most preinjury activities, and at 2-year follow-up, he continues to have good functional outcome. Endovascular repair may be successfully employed in select aortic injuries in hemodynamically stable patients.

    The management of complex abdominal wall defects is challenging and often requires an individualized strategy with additional measures to minimize morbidity and recurrence. We retrospectively reviewed all patients who underwent reconstruction of complex abdominal wall defects at Emory Hospital by the senior author over a 7-year period. Abdominal hernia defects were categorized into primary, secondary, and tertiary hernias; infection; composite tumor defects; and dehiscence. Charts were queried for comorbidities, surgical technique, and outcome measures such as complications and recurrence. A total of 165 patients included in the series, with an average age of 52 years, and an average body mass index of 38 kg/m. Mesh was used in 81.8% of cases, 77% of those (mesh) being acellular dermal matrices (ADM). Component separation was performed in 75 patients (45.4%). The overall complication rate was 23.6% (39/165) including infection, delayed healing, skin necrosis, and fistulae, and was higher in patients with 2 or more comorbidities and those who required synthetic mesh reconstruction. The hernia recurrence or bulge was observed in 20.6% (34/165), and 29.4% of these patients required an additional, equally complex procedure. Hernia recurrence was significantly associated with a history of previous recurrent hernia, and hypertension (P < 0.04 and P = 0.001, respectively). Recurrence was higher in patients with 2 or more comorbidities (26% vs. 14%, P = 0.022). The recurrence rate was similar for synthetic and ADM reconstructions; however, the complication rates were higher when synthetic mesh was used. Attention to surgical technique, optimization of comorbidities, and the increased use of biologic meshes will minimize the need for operative intervention of complications following reconstruction of complex abdominal wall defects. Components separation and ADM have been very useful additions to the surgical management in these high-risk patients.

    2005-11-01

    Abdominal aortic aneurysm (AAA) rupture is believed to occur when the mechanical stress acting on the wall exceeds the strength of the wall tissue. Therefore, knowledge of the AAA wall stress distribution could be useful in assessing its risk of rupture. In our research, a finite element analysis was used to determine the wall stresses both in idealized models and in a real clinical model in which the aorta was considered isotropic with nonlinear material properties and was loaded with a given pressure. In the idealized models, both maximum diameter and asymmetry were found to have substantial influence on the distribution of the wall stress. The thrombus inside the AAA was also found to help protecting the walls from high stresses. Using CT scans of the AAA, the actual geometry of the aneurysm was reconstructed and we found that wall tension increases on the flatter surface (typically corresponds to the posterior surface) and at the inflection points of the bulge. In addition to the static analysis, we also performed simulations of the effect of unsteady pressure wave propagation inside the aneurysm.

    As an abdominal aortic aneurysm develops, large changes occur in the composition and structure of the arterial wall, which result in its stiffening. So far, most studies, whether experimental or numerical, have been conducted assuming the walls to be rigid. A numerical simulation of the fluid structure interactions is performed in different models of aneurysms in order to analyze the effects that the wall compliance might have on the flow topology. Both symmetric and non-symmetric models of aneurysms are considered, all idealistic in shape. The wall mechanical properties are varied in order to simulate the progressive stiffening of the walls. The spatial and temporal distributions of wall tension are calculated for the different values of the wall elasticity and compared to the results for the rigid walls. In the case of rigid walls, the calculation of the wall shear stresses and pressure compare very well with experimental results.

    More than 90% of renal injuries in children result from blunt abdominal trauma. A 10-year-old female had a blunt abdominal trauma with macro-hematuria. The computed tomography scan revealed the presence of a horseshoe kidney and a 3rd grade renal lesion and contrast leakage from the right ureter. The ureteral rupture was confirmed by cystoscopy and ascendant pyelography and than a double J-stent was implanted. The stent was removed one month later. Non-surgical management has become the standard of care for both ureteral and renal lesions in children. Non-surgical treatment is a safe procedure for renal trauma with ureteral rupture in children.

    This study's objective was to identify clinical characteristics of patients with a blunt traumatic injury that increased the risk of peritoneal or pericardial fluid collections and abdominal organ injuries not identified by a bedside focused abdominal sonogram for trauma (FAST) examination. This observational study used a retrospective chart review of a cohort of patients identified through a query of the University of Nebraska Medical Center's trauma registry, a tertiary referral center for portions of Nebraska, Iowa, and Missouri. Adult patients presenting to the Emergency Department (ED) for an evaluation of blunt traumatic injury from September 1996 to December 2002 were eligible if their ED course included admission to the trauma service after completion of a bedside FAST examination (US) and a confirmatory study (Conf) such as an abdominopelvic computed tomography scan or exploratory laparotomy within 12 h of completion of the ED FAST examination. The medical records of those patients with a US+/Conf+ or US-/Conf+ examination were reviewed. Clinical characteristics were recorded on a standard data collection form. Statistically significant predictors of a US-/Conf+ examination were found using a stepwise logistic regression procedure. A query of the trauma registry for the study period revealed 1453 adult individuals with blunt abdominal trauma, with 458 patients meeting the inclusion criteria. The clinical characteristics of the 79 US+/Conf+ examinations were compared to those of the 53 US-/Conf+ examinations. The presence of a radiographically proven pelvic fracture (odds ratio 3.459; 95% confidence interval of 1.308-9.157) and a radiographically or operatively proven renal injury (odds ratio 3.667; 95% confidence interval of 1.013-13.275) were found to be significant predictors. The presence of a pelvic fracture or renal injury in adult victims of blunt abdominal trauma increases the likelihood of a US-/Conf+ examination. Patients with a negative FAST

    Low birth weight is associated with obesity in later life and a more central fat distribution has a positive correlation with cardiovascular disease. However, the correlation between visceral adiposity in newborns and birth size is unknown. We measured the visceral adiposity in 118 newborns using the abdominal wall fat index (AFI), ratio between the maximum thickness of preperitoneal and the minimum thickness of subcutaneous fat evaluated by ultrasound. There was a weak negative correlation between AFI and birth weight (r = -0.197; P = 0.033) but not with birth length (r = -0.118; P = 0.201), body mass index (r = -0.138; P = 0.176) and abdominal circumference (r = 0.063; P = 0.497). In conclusion, we suggest that AFI is a useful parameter for evaluating the fat distribution in newborns and that visceral adiposity has a weak negative correlation with birth weight.

    Over a 10-year period we reviewed the records of 370 consecutive patients with potentially penetrating abdominal wounds (48 gunshot and 322 stab wounds). Selective non-operative management for abdominal stab wounds was introduced, guided by serial physical examination. In our study the terms therapeutic and non-therapeutic laparotomies were used, the latter comprising negative as well as insignificant findings. Initially diagnostic peritoneal lavage and local wound exploration were used, but these methods were later abandoned. Mortality was 10.2% and morbidity 25% in the group of gunshot wounds and 1.2% and 8.6% in the group of stab wounds. During this period the rate of laparotomies for stab wounds decreased from 55% to 30%, while the rate of non-therapeutic laparotomies decreased from 24% to 0% in the last year. Delayed laparotomy did not cause death or increase morbidity. Our results support the concept of selective non-operative management of abdominal stab wounds using repeated physical examination. Peritoneal perforation and haemoperitoneum should not be an indication for routine laparotomy.

    Objectives To determine what proportion of abdominal computed tomography (CT) scans ordered after blunt trauma are positive and the applicability and accuracy of existing clinical prediction rules for obtaining a CT scan of the abdomen in this setting. Setting A leading trauma hospital, affiliated with the University of Ottawa. Design A retrospective cohort study. Patients and methods All patients with blunt trauma admitted to hospital over a 1-year period having an Injury Severity Score (ISS) greater than 12 who underwent CT of the abdomen during the initial assessment. Recorded data included age, sex, Glasgow Coma Scale (GCS) score, ISS, type of injuries, number of abdominal CT scans ordered, and scan results. Two clinical prediction rules were found in the literature that identify patients likely to have intra-abdominal injuries. These rules were applied retrospectively to the cohort. The predicted proportion of positive CT scans was compared with the observed proportion, and the sensitivity, specificity, and accuracy were estimated. Results Of the 297 patients entered in the study, 109 underwent abdominal CT. The median age was 32 years, 71% were male and the median ISS was 24. In only 36.7% (40 of 109) of scans were findings suggestive of intra-abdominal injuries. Application of one of the clinical prediction rules gave a sensitivity of 93.8% and specificity of 25.5% but excluded 23% of patients because of a GCS score less than 11. The second prediction rule tested could be applied to all patients and was highly sensitive (92.5%) and specific (100.0%). Conclusions The assessment of the abdomen in blunt trauma remains a challenge. Accuracy in predicting positive scans in equivocal cases is poor. Retrospective application of an existing clinical prediction rule was found to be highly accurate in identifying patients with positive CT findings. Prospective use of such a rule could reduce the number of CT scans ordered without missing significant injuries. PMID

  19. Changes in wall shear stresses in abdominal aortic aneurysms with increasing wall stiffness

    NASA Astrophysics Data System (ADS)

    Salsac, Anne-Virginie; Fernandez, Miguel

    2006-11-01

    During the growth of abdominal aortic aneurysms, local changes occur in the composition and structure of the diseased wall, resulting in its stiffening. A numerical simulation of the fluid structure interactions is performed in idealized models of aneurysms using a finite element method. A full coupling of the equations governing the pulsatile blood flow and the deformation of the compliant wall is undertaken. The effect of the progressive stiffening of the wall is analyzed at various stages in the growth of the aneurysm. Increasing the wall stiffness alters the distribution of wall shear stresses and leads to an increase in their magnitude. The wall compliance is shown to have a more pronounced effect on non-axisymmetric aneurysms, which sustain large displacements. The overall movement of the aneurysm models increases the three-dimensionality of the flow.

    Liver injury in blunt abdominal trauma is common. However, not often does blunt trauma cause injury to the anatomical structures of the porta hepatis. Isolated injury of the hepatic artery has been rarely reported in the literature. Such injury may be lethal and requires immediate diagnosis and management. This report describes an unusual case of blunt abdominal trauma resulting in hepatic and gastroduodenal artery dissection, with pseudoaneurysm formation complicated by active upper gastrointestinal bleeding. The injury was managed by transcatheter embolisation. Awareness of this diagnosis should facilitate management of similar trauma cases.

    In this article, we present the first case of necrotizing fasciitis affecting the abdominal wall caused by Serratia marcescens and share results of a focused review of S. marcescens induced necrotizing fasciitis. Our patient underwent aorto-femoral bypass grafting for advanced peripheral vascular disease and presented 3 weeks postoperatively with pain, erythema and discharge from the incision site in the left lower abdominal wall and underwent multiple debridement of the affected area. Pathology of debrided tissue indicated extensive necrosis involving the adipose tissue, fascia and skeletal muscle. Wound cultures were positive for Serratia marcescens. She was successfully treated with antibiotics and multiple surgical debridements. Since necrotizing fasciitis is a medical and surgical emergency, it is critical to examine infectivity trends, clinical characteristics in its causative spectrum. Using PubMed we found 17 published cases of necrotizing fasciitis caused by Serratia marcescens, and then analyzed patterns among those cases. Serratia marcescens is prominent in the community and hospital settings, and information on infection presentations, risk factors, characteristics, treatment, course, and complications as provided through this study can help identify cases earlier and mitigate poor outcomes. Patients with positive blood cultures and those patients where surgical intervention was not provided or delayed had a higher mortality. Surgical intervention is a definite way to establish the diagnosis of necrotizing infection and differentiate it from other entities.

    The management of primary and recurrent giant incisional hernias remains a complex and frustrating challenge even with multiple alloplastic and autogenous closure options. The purpose of this study was to develop a reconstructive technique of restoring abdominal wall integrity to a subcategory of patients, who have failed initial hernia therapy, by performing superior and lateral myofascial release. Over a 1.5-year period, 10 patients with previously unsuccessful treatment of abdominal wall hernias, using either primary repair or placement of synthetic material, were studied. The patients had either recurrence of the hernia or complications such as infections requiring removal of synthetic material. The hernias were not able to be treated with standard primary closure techniques or synthetic material. The average defect size was 19 x 9 cm. Each patient underwent wide lysis of bowel adhesions releasing the posterior abdominal wall fascia to the posterior axillary line, subcutaneous release of the anterior abdominal wall fascia to a similar level, and complete removal of any synthetic material (if present). The abdominal domain was reestablished by releasing the laterally retracted abdominal wall. The amount of available abdominal wall tissue was increased by wide release of the cephalic abdominal wall fascia overlying the costal margin and the external oblique fascia and muscle laterally. If needed, partial thickness of the internal oblique muscle and its anterior fascia were also released laterally to perform a tension-free primary closure of the defect. All repairs were closed with satisfactory functional and aesthetic results. All alloplastic material was removed. Fascial release was limited so as to close only the hernia defect without tension. No significant release of the rectus sheath and muscle was needed. Good, dynamic muscle function was noted postoperatively. All repairs have remained intact, and no further abdominal wall hernias have been noted on follow-up.

    Introduction Clinical practice guidelines are structured recommendations that help physicians and patients to make proper decisions when dealing with a specific clinical condition. Because blunt abdominal trauma causes a various range of mild, single-system, and multisystem injuries, early detection will help to reduce mortality and resulting disability. Emergency treatment should be initiated based on CPGs. This study aimed to determine the variables affecting implementing blunt abdominal trauma CPGs in an Iranian hospital. Methods This study was conducted as a qualitative and phenomenology study in the Family Hospital in Tehran (Iran) in 2015. The research population included eight experts and key people in the area of blunt abdominal trauma clinical practice guidelines. Sampling was based on purposive and nonrandom methods. A semistructured interview was done for the data collection. A framework method was applied for the data analysis by using Atlas.ti software. Results After framework analyzing and various reviewing and deleting and combining the codes from 251 codes obtained, 15 families and five super families were extracted, including technical knowledge barriers, economical barriers, barriers related to deployment and monitoring, political will barriers, and managing barriers. Conclusion Structural reform is needed for eliminating the defects available in the healthcare system. As with most of the codes, subconcepts and concepts are classified into the field of human resources; it seems that the education and knowledge will be more important than other resources such as capital and equipment.

    Blunt trauma patients with rib fractures were studied to determine whether the number of rib fractures or their patterns were more predictive of abdominal solid organ injury and/or other thoracic trauma. Rib fractures were characterized as upper zone (ribs 1 to 4), midzone (ribs 5 to 8), and lower zone (ribs 9 to 12). Findings of sternal and scapular fractures, pulmonary contusions, and solid organ injures (liver, spleen, kidney) were characterized by the total number and predominant zone of ribs fractured. There were 296 men and 14 women. There were 38 patients with scapular fracture and 19 patients with sternal fractures. There were 90 patients with 116 solid organ injuries: liver (n = 42), kidney (n = 27), and spleen (n = 47). Lower rib fractures, whether zone-limited or overlapping, were highly predictive of solid organ injury when compared with upper and midzones. Scapular and sternal fractures were more common with upper zone fractures and pulmonary contusions increased with the number of fractured ribs. Multiple rib fractures involving the lower ribs have a high association with solid organ injury, 51 per cent in this series. The increasing number of rib fractures enhanced the likelihood of other chest wall and pulmonary injuries but did not affect the incidence of solid organ injury. PMID:20726423

    In a woman patient aged 80 years under anticoagulation with dicumarol (Marcumar), abdominal pain suddenly occurred which was located on the right side as well as signs of acute bleeding. Preoperative sonography and computer scan showed a large, cystic tumour, most likely originating from the right ovary with infiltration of the abdominal wall. Intraoperative diagnosis was a large haematoma of the abdominal wall and the retroperitoneum penetrating into the free abdomen.

    Context: Abdominal compartment syndrome (ACS) is associated with high morbidity and mortality among trauma patients. Several clinical and laboratory findings have been suggested as markers for ACS, and these may point to different types of ACS and complications. Aims: This study aims to identify the strength of association of clinical and laboratory variables with specific adverse outcomes in trauma patients with ACS. Settings and Design: A 5-year retrospective chart review was conducted at three Level I Trauma Centers in the City of Chicago, IL, USA. Subjects and Methods: A complete set of demographic, pre-, intra- and post-operative variables were collected from 28 patient charts. Statistical Analysis: Pearson's correlation coefficient was used to determine the strength of association between 29 studied variables and eight end outcomes. Results: Thirty-day mortality was associated strongly with the finding of an initial intra-abdominal pressure >20 mmHg and moderately with blunt injury mechanism. A lactic acid >5 mmol/L on admission was moderately associated with increased blood transfusion requirements and with acute renal failure during the hospitalization. Developing ACS within 48 h of admission was moderately associated with increased length of stay in the Intensive Care Unit (ICU), more ventilator days, and longer hospital stay. Initial operative intervention lasting more than 2 h was moderately associated with risk of developing multi-organ failure. Hemoglobin level <10 g/dL on admission, ongoing mechanical ventilation, and ICU stay >7 days were moderately associated with a disposition to long-term support facility. Conclusions: Clinical and lab variables can predict specific adverse outcomes in trauma patients with ACS. These findings may be used to guide patient management, improve resource utilization, and build capacity within trauma centers. PMID:27162436

    Extrahepatic bile duct traumatic injuries are extremely rare and their treatment is difficult and with several controversies. The aim of this study was to offer some more clinical information on their surgical repair and outcome. We present seven patients with extrahepatic biliary tract lesions after blunt abdominal trauma, (isolated gallbladder lesions were excluded) four males and three females from 23 to 51 years of age (mean age 35.1 years). All patients had suffered high-energy blunt abdominal trauma and presented associated injuries, mostly liver trauma and lung contusions. Six gallbladder lesions and six common bile duct injures were identified; a right hepatic duct laceration and a left hepatic duct transection were also present. Injuries were treated either with primary repair or with duct-jejunal anastomoses with Roux-en-Y reconstruction. Principal complications were postoperative anastomotic leakage (1 case) and recurrent cholangitis (3 cases) with or without stricture. Not-diagnosed injuries caused substantial morbidity. We prefer and recommend the use of primary repair in partial ruptures with no significant tissue loss and biliary-enteric anastomoses in large injuries and complete transections because they offer the best long-term drainage with less risk of stricture formation than end-to-end anastomoses. We defend the use of long duration (6 to 9 months) transanastomotic stents. PMID:11596896

    This study represents the experience with blunt trauma to the abdomen of patients from a major regional trauma center. Eight hundred and seventy patients with blunt abdominal trauma are reviewed, representing 12.89% of the total admissions over a 5-year period. The motor vehicle continues to be the major cause (89.5%) of injury to these patients. Thirty per cent had positive blood alcohol. Intra-abdominal injuries in this group necessitating operative intervention were based on the use of peritoneal lavage. Negative celiotomies occurred in 10.2% of these patients. Of the injuries incurred, the spleen was involved 42%, the liver 35.6%, the serosa, diaphragm, bowel, and blood vessels were involved to a lesser extent. Only 0.4% of the patients suffered direct injury to the stomach, duodenum, and pancreas, data which should preclude routine exploration of retroperitoneal structures unless by obvious retroperitoneal injury is noted. Additional surgical intervention for associated injuries was seen in 50.54% of this patient group. PMID:6712323

    Abdominal fistula caused by cholesterol gallstones, which remained in the abdominal wall after laparascopic cholecystectomy: a laparascopic cholecystectomy was performed in a 60-years-old man who was diagnosed as acute necrosing cholecystitis due to cholecystolithiasis. After removal of the gallbladder using an Endocath some gallstones remained in the excision channel of the abdominal wall. Therefore, a fistula developed in the excision channel postoperatively. As the wound healing was disturbed an investigation of the abdominal wall was performed by ultrasound. In the former excision channel several small, oval, formations with high echogenicity and faint ultrasound shadows were detected, corresponding to additional gallstones. After excision of granulation tissue and removal of the cholesterol stones, complete healing of the fistula in the abdominal wall was achieved. PMID:12044854

    Trauma is the leading cause of death in children in developed countries. In tropical Africa, it is only beginning to assume importance as infections and malnutrition are controlled. In developed countries, the availability of advanced imaging modalities has now reduced the necessity for laparotomy to less than 10% following blunt abdominal trauma (BAT) in children. This report reviews the epidemiology, management, and unnecessary laparotomies for pediatric BAT in a developing country in a retrospective review of 57 children aged 15 years or less at the Ahmadu Bello University Teaching Hospital, Zaria, Nigeria over 12 years. The average age was 9 years and the male-female ratio 3.8:1. Seventy-four percent (74%) of abdominal injuries in children were due to blunt trauma. The commonest causes of injury were road traffic accidents (RTA) (57%), 88% in pedestrians and 59% in children aged 5-9 years. Falls were the cause of trauma in 36%, 60% of them aged 10-15 years. Other causes of injury were sports in 5% and animals in 2%. Diagnosis was clinical, supported by diagnostic peritoneal lavage or paracentesis. Two patients had ultrasonography, and none had computed tomography. Fifty-three patients had a laparotomy, 2 died before surgery, 1 was managed nonoperatively, and in 1 surgery was declined. There were 34 splenic injuries, 20 treated by splenic preservation, splenectomy in 13, and non-operative in 1. Fourteen gastrointestinal injuries were treated in 12 patients. Of 9 hepatic injuries, 4 were minor and were left untreated, 3 were repaired, 1 was packed to arrest hemorrhage, and a lacerated accessory liver was excised. Four injuries to the urinary tract (bladder contusion 2, bladder rupture 1, ruptured hydronephrotic kidney 1) were treated accordingly. There were 4 retroperitoneal hematomas associated with other intra-abdominal injuries and 2 pancreatic contusions. One lacerated gallbladder was treated by cholecystectomy and a ruptured left hemidiaphragm was repaired

    Objective: To determine the presentation, anatomical distribution, diagnostic method, management and outcome of hollow viscus injury (HVI) from blunt abdominal trauma. Methods: This  was  a  retrospective  cross-ecnal  study  including  patients  with  blunt  abdominal  trauma leading to HVI admitted at Rajendra Institute of Medical Sciences, Ranchi, over a period of 4.5 years (January 2009 to July 2014). Data were retrieved from patients’ medical records. Total 173 patients with HVI due to blunt abdominal trauma, who underwent laparotomy at our institute, were reviewed. Data regarding clinical presentation, anatomical distribution, management and outcome were recorded and analysed. Results: Out of 173 patients 87.1% were men and 12.9% were women. Mean age of patients was 29±14.02 years. The most common site of injury was ileum (46.2%) followed by jejunum (44.5%). There were 5 gastric perforations (2.9%), 2 (1.15%) duodenal, 2 (1.15%) colonic, 2 (1.15%) sigmoidal and 2 (1.15%) rectal injuries. One caecal injury was also recorded. Road traffic accident was the most common mechanism of injury (57.2%) followed by fall from height (36.4%) and assault (6.4%). Free gas under diaphragm on erect abdomen radiography was seen in 85.5% of cases while preoperative CT Abdomen was done in 11.6% of cases. Treatment consisted of simple closure of the perforation (66.5%), resection and anastomosis (11.0%) and stoma (22.5%). Major complication was anastamotic leak which was recorded in 6.4% cases and 15.6% patients developed burst abdomen. Average hospital stay was 13±6 days. Overall mortality rate was 12.7%. Conclusion: Although early recognition of intestinal injuries from blunt abdominal trauma may be difficult in all cases, it is very important due to its tremendous life threatening potential. Age of the patient, anatomical site and time of presentation are probably main prognostic factors. PMID:27162889

    The number of organ donors is limited by many contraindications for donation and poor quality of potential organ donors. Abdominal infection is a generally accepted contraindication for donation of abdominal organs. We present a 43-year-old man with lethal brain injury, blunt abdominal trauma, and intestinal perforation. After withdrawal of life-sustaining treatment and circulatory arrest, a minilaparotomy confirmed abdominal contamination with intestinal content. After closure of the abdomen, organs were preserved with in situ preservation with an aortic cannula inserted via the femoral artery. Thereafter, the kidneys were procured via bilateral lumbotomy to reduce the risk of direct bacterial contamination; lungs were retrieved following a standard practice. There was no bacterial or fungal growth in the machine preservation fluid of both kidneys. All organs were successfully transplanted, without postoperative infection, and functioned well after 6 months. We hereby show that direct contamination of organs can be avoided with the use of in situ preservation and retroperitoneal procurement. Intestinal perforation is not an absolute contraindication for donation, although the risk of bacterial or fungal transmission has to be evaluated per case. PMID:27500248

    With the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. However, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. Injuries may consist of traumatic abdominal wall disruption. We present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair. A review of the literature is provided. Two patients were brought in after a high velocity Motor Vehicle Collision. Both presented with an acute abdomen and a seatbelt sign upon which the decision was made to perform emergency laparotomies. Both patients had an abdominal wall disruption along the seatbelt sign. These disruptions were primarily closed and during six months of follow-up no complications occurred. A disruption of the abdominal wall is a rare complication. However, it is a diagnosis that may not be missed as patients have a higher risk of morbidity and mortality. CT-scanning is an accurate method to detect disruptions. Closure of blunt traumatic abdominal wall disruption can be done primarily with sutures or addition of a mesh. In both cases of the severe abdominal wall disruption, primary repair without mesh in the acute phase was successful. When a laparotomy is not indicated, the abdominal wall must be assessed for disruption. If there is a disruption primary repair is a good option. PMID:27331068

    Myofascial defects of lateral abdominal wall and lumbar region occur chiefly after lumbotomy--the most popular access in urosurgery. Meanwhile lumbotomy remains one of the most traumatic accesses through the lateral abdominal wall. Myofascial defects were diagnosed in 48,9% of operated patients with lumbotomy. Of them true postoperative hernias were found in 35,3%; neuropathic hernias - in 13,6%. Since 2002 the originally developed method of lateral abdominal wall reconstruction had been used for the treatment of such patients. The immediate and long-term results (maximal follow-up period 5 years) showed no hernia recurrence or complications in 26 operated patients.

    Computed tomography (CT) is the imaging method of choice in the assessment of multiple trauma patients. However, in patients who suffered from low-energy abdominal trauma, the use of CT is controversial, since the probability of injury is low and therefore most of the studies are normal. Thus, conventional US imaging has increasingly been employed as the initial imaging modality in the work-up of minor traumatic emergency condition. More recently, the introduction of a new contrast-enhanced ultrasound (CEUS) technique, using second-generation ultrasound contrast agents, has led to a notable increase in the diagnostic accuracy of US in many organs. Therefore, in trauma patients, following assessment with conventional US imaging, a CEUS exam can be performed, to provide a more reliable assessment of solid organ injuries. CEUS has the potential to detect active bleeding from a variety of traumatic origins. Similar to CT, active extravasation is considered when there is evidence of contrast agent collection with echogenicity similar to that of an adjacent vessel. On the other hand, at least some drawbacks have to be addressed, including operator competence and reduced panoramic view. Moreover, CEUS, like conventional US imaging, cannot depict some lesions, such as diaphragmatic ruptures, bowel, and mesenteric traumatic injuries. This technique represents a non-invasive and repeatable method that can be performed at patient's bedside and is therefore extremely helpful for the follow-up of solid organs traumas managed conservatively, especially in pediatric patients and women of fertile age. Moreover, it may reduce the number of CT scans and expedite patient discharge.

    Despite centuries of anatomical studies, controversies and contradictions still exist in the literature regarding the definition, anatomical terminology and the limits of the abdominal wall. We conducted a systematic research of books published from 1901 until December 2012 in Google Books. After the index screening, 16 remaining books were further assessed for eligibility. We decided to exclude journals. The aim of the study was to focus on surface landmarks and borders of the abdominal cavity. After this revision of the literature, we propose that the surface landmarks of the abdominal wall should be standardized. PMID:25097589

    Chronic abdominal pain is a common symptom with an extensive differential diagnosis. The work-up is frequently costly, yet many patients elude definitive diagnosis. We describe 12 obese women with long-standing abdominal pain, many of whom eluded diagnosis but who met criteria for abdominal wall pain. Each patient underwent a focused history and physical examination which included checking for Carnett’s sign and performing a “pinch test”. All patients had positive Carnett’s sign and pinch tests. An injection of local anaesthetic, with or without corticosteroid, completely relieved the pain within 10 min. Of the six patients seen in follow-up, four remained pain free and two responded to a second injection of local anaesthetic. Abdominal wall pain is an under-appreciated cause of chronic abdominal pain. Diagnosis is often straightforward and treatment with a local injection of anaesthetic is both diagnostic and curative.

    Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea. PMID:22880189

    During laparoscopic cholecystectomy, perforation of the gallbladder can occurs in < or = 20% of cases, while gallstone spillage occurs in < or = 6% of cases. In most cases, there are no consequences. Gallstones can be lost in the abdominal wall as well as the abdomen during extraction of the gallbladder. The fate of such lost gallstones, which can lead to the formation of an abscess, an abdominal wall mass, or a persistent sinus, has not been studied adequately. Herein we report the case of a persistent sinus of the abdominal wall after an emergent laparoscopic cholecystectomy in an 82-year-old woman with gangrenous cholecystitis and perforation of the friable wall in association with an empyema of the gallbladder. The culture of the obtained pus was positive for Escherichia coli. After a small leak of dirty fluid from the wound of the epigastric port site of 4 months' duration, surgical exploration under local anesthesia revealed that the sinus was caused by spilled gallstones impacting into the abdominal wall between the posterior sheath and left rectus abdominalis muscle. The removal of the stones resulted in complete healing. Long-term complications after laparoscopic cholecystectomy involving the abdominal wall are rare but important possible consequences that could be avoided. PMID:11967704

    Typical human paragonimiasis demonstrates an elevated eosinophil count, positive immunoblot, nodular shadows of the lung and pleural thickening with pleural effusion, and these symptoms may be confused with chest cancer. In the present case, a rare case of human paragonimiasis mimicking chest cancer and abdominal wall metastasis is described, the 39-year-old male patient was admitted in our hospital for cough, weight loss 5 kg and a firm mass in right upper abdominal wall. The laboratory test showed unremarkable hematology and biochemistry results. Chest X-ray, Plain computed tomography of the chest and abdomen showed right pleural effusion, several nodules in right lower lung and a mass in the right upper abdominal wall. The initial diagnosis was lung or chest cancer with abdominal wall metastasis, and the abdominal wall mass was resected for the final diagnosis. The biopsy revealed eosinophilic granuloma with Charcot-Leyden crystal formation infiltrated in the muscular fibers. Subsequent to assessment of the antibodies against parasites, the final diagnosis of paragonimiasis was made. PMID:27313691

    Purpose: The treatment of ventral hernias (VH) has been a challenging problem for medical care. Repair of these hernias is fraught with failure; recurrence rates ranging from 24% to 43% have been reported, even with the use of biocompatible mesh. Currently, computed tomography (CT) is used to guide intervention through expert, but qualitative, clinical judgments, notably, quantitative metrics based on image-processing are not used. The authors propose that image segmentation methods to capture the three-dimensional structure of the abdominal wall and its abnormalities will provide a foundation on which to measure geometric properties of hernias and surrounding tissues and, therefore, to optimize intervention.Methods: In this study with 20 clinically acquired CT scans on postoperative patients, the authors demonstrated a novel approach to geometric classification of the abdominal. The authors’ approach uses a texture analysis based on Gabor filters to extract feature vectors and follows a fuzzy c-means clustering method to estimate voxelwise probability memberships for eight clusters. The memberships estimated from the texture analysis are helpful to identify anatomical structures with inhomogeneous intensities. The membership was used to guide the level set evolution, as well as to derive an initial start close to the abdominal wall.Results: Segmentation results on abdominal walls were both quantitatively and qualitatively validated with surface errors based on manually labeled ground truth. Using texture, mean surface errors for the outer surface of the abdominal wall were less than 2 mm, with 91% of the outer surface less than 5 mm away from the manual tracings; errors were significantly greater (2–5 mm) for methods that did not use the texture.Conclusions: The authors’ approach establishes a baseline for characterizing the abdominal wall for improving VH care.

    Patient: Male, 3-day Final Diagnosis: Ectopic right testis in anterior abdominal wall Symptoms: — Medication: — Clinical Procedure: Testicular ultrasound and MRI abdomen Specialty: Radiology Objective: Unusual clinical course Background: Abnormal testicular descent can either be undescended or, less commonly, ectopic. Most undescended testes complete the course of descent by the first year of life only if these remain in the normal path of descent. The deviation of the testis may occur to an ectopic location during the transinguinal phase. Of the known ectopic sites, the anterior abdominal wall is the rarest site of testicular ectopia and to our knowledge only 3 cases of this nature have been reported in the available literature to date. Case Report: This rare case of testicular ectopia occurred in a 3-day-old boy in whom the right scrotal sac was empty; on abdominal ultrasound, the right testis was found in the subcutaneous tissues of the right antero-lateral abdominal wall. These findings were confirmed on abdominal MRI, where the right testis was seen beneath the skin between the subcutaneous tissues and external oblique aponeurosis. No aponeurotic or muscular defect was appreciable under the abdominal wall. The neonate underwent orchiopexy at the age of 6 months and remained uneventful postoperatively. Conclusions: Preoperative imaging is recommended to detect and confirm the ectopic site as well as the morphology of testis, thereby increasing the chance of surveillance and preservation of an ectopic testis. Imaging can serve as preoperative road mapping to localize the exact site for surgical exploration of an ectopic testis if there is no apparent or palpable swelling over the anterior abdominal wall.

    Positron emission tomography with [(18)F]-fluorodeoxyglucose provides functional and anatomic information by visualising the uptake of radiolabelled glucose in tumour and inflammatory cells. We report delayed diagnosis of necrosis of the gastric fundus after blunt abdominal trauma in a 73-year-old man. After a car accident with head-on collision, the patient was stabilised in our emergency room. His femur was treated by internal fixation, his ellbow was stabilised by a fixateur externe. During surgery his status deteriorated. The patient was in need of high dosage of inotrops during the following days. He had a biventricular pacemaker implanted because of ischemic myocardiopathy, and he suffered from renal insufficiency. Over the next days, his haemodynamics improved. A central venous line had to be removed because of ensuing septic fever. The patient complained of upper abdominal pain and nausea. A sonography and computer tomography without contrast medium were performed with negative result. Because of contamination of the central venous line with Staphylococcus epidermidis the pacemaker was evaluated for infection by transoesophageal echocardiography, again without any findings. Because of ongoing fever and positive inflammatory markers a positron emission tomography was indicated, as a contrast examination and a magnetic resonance examination were not feasible because of the renal insufficiency and the pacemaker, respectively. Prophylactic removal of the pacemaker would have been a substantial risk for the patient due to his underlying myocardiopathy. Positron emission tomography showed an increased tracer uptake in the gastric fundus, which turned out to be necrotic by endoscopy. A laparoscopic resection followed, and drainage of an abscess, which had evolved subsequently between stomach and spleen stopped the inflammatory process. This case report demonstrates that positron emission tomography may be an alternative to computer tomography with contrast medium

    Background Incisional hernias are a complication in 10% of all open abdominal operations and can result in significant morbidity. The purpose of this study is to determine if inhibiting abdominal muscle contraction influences incisional hernia formation during laparotomy healing. We hypothesize that reducing abdominal musculature deformation reduces incisional hernia occurrence and size. Study Design Using an established rat model for incisional hernia, a laparotomy through the linea alba was closed with one mid-incision, fast-absorbing suture. Three groups were compared: a SHAM group (SHAM; n = 6) received no laparotomies while the Saline Hernia (SH; n = 6) and Botox Hernia (BH; n = 6) groups were treated once with equal volume saline or Botulinum Toxin (Botox®, Allergan) before the incomplete laparotomy closure. On post-operative day 14, the abdominal wall was examined for herniation and adhesions and contractile forces were measured for abdominal wall muscles. Results No hernias developed in SHAM rats. Rostral hernias developed in all SH and BH rats. Caudal hernias developed in all SH rats, but in only 50% of the BH rats. Rostral hernias in the BH group were 35% shorter and 43% narrower compared to those in the SH group (p < 0.05). The BH group had weaker abdominal muscles compared to the SHAM and SH groups (p < 0.05). Conclusions In our rat model, partial paralysis of abdominal muscles reduces the number and size of incisional hernias. These results confirm abdominal wall muscle contractions play a significant role in the pathophysiology of incisional hernia formation. PMID:25817097

    We report a case of a previously healthy woman after an uneventful caesarean section who developed polymicrobial necrotizing fasciitis. She was given a non-steroidal anti-inflamatory drug (NSAID) after her delivery. Her post-delivery course was complicated by septic shock, and required multiple debridements before abdominal reconstruction. This case describes the increased risk of necrotizing fasciitis with NSAID use. Unusual were the organisms causing the polymicrobial necrotizing fasciitis: Staphylococcus aureus, Enterobacter agglomerans, Acinetobacter baumannii, and two strains of Enterobacter cloacae.

    Gallbladder (GB) perforation is a very rare posttraumatic abdominal injury. It is potentially life-threatening, and good outcome requires early diagnosis. We present a case of isolated posttraumatic GB perforation in which the precise sonographic (US) diagnosis led us to apply proper management. Color Doppler US showed a clear to-and-fro flow signal passing through the perforation site, and contrast-enhanced US confirmed the presence of a small defect in the GB wall. When examining posttraumatic patients, the possibility of GB perforation must be kept in mind. Color Doppler US and contrast-enhanced US are the examinations of choice to detect the perforation site and show bile movement through the perforation.

    Purpose: Quantitative measurements of wall thickness in human abdominal aortic aneurysms (AAAs) may lead to more accurate methods for the evaluation of their biomechanical environment. Methods: The authors describe an algorithm for estimating wall thickness in AAAs based on intensity histograms and neural networks involving segmentation of contrast enhanced abdominal computed tomography images. The algorithm was applied to ten ruptured and ten unruptured AAA image data sets. Two vascular surgeons manually segmented the lumen, inner wall, and outer wall of each data set and a reference standard was defined as the average of their segmentations. Reproducibility was determined by comparing the reference standard to lumen contours generated automatically by the algorithm and a commercially available software package. Repeatability was assessed by comparing the lumen, outer wall, and inner wall contours, as well as wall thickness, made by the two surgeons using the algorithm. Results: There was high correspondence between automatic and manual measurements for the lumen area (r=0.978 and r=0.996 for ruptured and unruptured aneurysms, respectively) and between vascular surgeons (r=0.987 and r=0.992 for ruptured and unruptured aneurysms, respectively). The authors' automatic algorithm showed better results when compared to the reference with an average lumen error of 3.69%, which is less than half the error between the commercially available application Simpleware and the reference (7.53%). Wall thickness measurements also showed good agreement between vascular surgeons with average coefficients of variation of 10.59% (ruptured aneurysms) and 13.02% (unruptured aneurysms). Ruptured aneurysms exhibit significantly thicker walls (1.78{+-}0.39 mm) than unruptured ones (1.48{+-}0.22 mm), p=0.044. Conclusions: While further refinement is needed to fully automate the outer wall segmentation algorithm, these preliminary results demonstrate the method's adequate reproducibility

    Abdominal wall injuries are reported to be less common than actually perceived by sports medicine practitioners. National Collegiate Athletic Association injury statistics for 2004-2005 cite a high of 0.71 abdominal muscle injuries per 1000 player-hours in wrestling competition to a low of 0.01 injuries per 1000 player-hours in autumn football practices. British professional soccer clubs reported an incidence of "torso" injuries of up to 7% of all injuries over the course of several seasons. Injury definition is most likely the explanation for this discrepancy. The abdominal wall muscles (rectus abdominis, external and internal obliques, and transverse abdominis) are injured by direct blows to the abdomen or by sudden or repetitive trunk movement, either rotation or flexion/extension. With the exception of the rare rectus sheath hematoma that does not self-tamponade, the treatment for these problems is nonoperative with symptoms guiding rehabilitation and return to play decisions.

    Background The laparoscopic ventral hernia repair technique made possible surgeries with smaller skin incisions and smaller dissection of the soft tissue around the hernia, therefore with a better wound, a quicker postoperative recovery and a lower complication rate. Aim To evaluate the applicability of a quality of life survey based on the molds of the American Hernia Society, European Hernia Society and Carolinas Equation for Quality of Life, through telephone in patients submitted to laparoscopic hernioplasty by IPOM technique. Methods A retrospective cohort study was made to evaluate the quality of life of 21 patients that underwent anterior abdominal wall laparoscopic hernioplasty by intraperitoneal onlay mesh technique. Questionnaire was applied through telephone. Results Of the 21 patients, 19% felt that the hernia recurred. Also 19% passed through another abdominal wall surgery, and among these, 75% was related to the previously hernia correction. Finally, 81% of patients did not undergo any other abdominal wall surgery. Conclusion It was possible to apply the quality of life questionnary by telephone on patients who underwent an anterior abdominal wall. The results, in its turn, were satisfactory and showed that patients, in general, were satisfied with the surgical procedure. PMID:24676295

    Multiple techniques have been used for the repair of complex abdominal wall defects after recurrent incisional hernias with varying rates of success. Primary repair has been associated with high recurrence rates, and prosthetic mesh placement is contraindicated in contaminated surgical fields. The development of biologic prostheses has changed the approach to these difficult problems. This study evaluates the management of complex abdominal wall defects using acellular porcine dermal collagen. Between August 2006 and May 2007, 18 patients underwent abdominal wall reconstruction for complex defects with acellular porcine dermal collagen (CollaMend; Bard Inc., Warwick, RI). Patient demographics, preoperative risk factors, previous herniorrhaphy attempts, postoperative complications, recurrences, and long-term results were retrospectively reviewed. Records were reviewed at a mean follow up of 7.3 months; the recurrence rate was 44.4 per cent. A total of 38.9 per cent (seven of 18) developed a postoperative wound complications, including infection in 22.2 per cent (four of 18). All of the patients with infection required prosthesis removal as a result of encapsulation rather than incorporation of the biologic prosthesis. Acellular porcine dermal collagen has the potential for reconstruction of abdominal wall defects with postoperative wound occurrences comparable with other biologic materials. Encapsulation of the material was a major problem in cases with wound infection that required graft removal rather than local wound measures. Hernia recurrence and dehiscence of the graft were problems in noncompromised surgical fields.

    An analysis of complex examination and treatment of 151 patients after planned and performed surgical interventions on organs of the retroperitoneal space was made. The patients were divided into 4 groups. The first group (of comparison) included 46 patients who were treated by lumbotomy for different diseases of organs of the urinary system. In 35 patients of the second group (prophylactics) the indications were determined and in 20 patients preventive endoprosthesis of the lateral abdominal wall using polypropylene endoprosthesis was fulfilled. Herniotomy with plasty of the lateral abdominal wall using local tissues was fulfilled in 30 patients. Prosthesing hernioplasty of the lateral abdominal wall was fulfilled in 40 patients of the main group. It was found that preventive endoprosthesis of the lateral abdominal wall allowed prevention of progressing anatomo-functional i/isufficiency and the appearance of postoperative hernias. The application of polypropylene endoprosthesis for the treatment of postoperative hernias allows obtaining 36.4% more good results as compared with the control group, 21.7% decreased number of satisfactory results and no recurrent hernias.

    2006-01-01

    INTRODUCTION Despite advances in trauma care, significant morbidity and mortality exists which could be reduced if all injuries were immediately identified. Two treatable factors are hypoxia and hypovolaemia which may occur secondary to haemorrhage into the chest and abdomen. Pneumothorax is also a frequent cause of preventable trauma death. Clinical examination is limited and we often rely on imaging. Anecdotally, it seemed some patients were investigated too quickly because their injuries had not evolved sufficiently enough to become detectable. In these patients, repeated assessments and imaging would, therefore, be necessary. PATIENTS AND METHODS This was a retrospective study looking at all patients over a 15-month period with significant chest and abdominal injuries. Patients with a chest or abdominal Abbreviated Injury Score (AIS) of 3 or above were identified. As a cross reference, those patients who required at least one chest drain, or a laparotomy within 24 h of admission were also identified. Case notes and films were reviewed with particular attention to the presence of initial ‘normal’ imaging. RESULTS A total of 1036 patients were eligible for entry into the trauma database; of these, 170 patients had chest and/or abdominal injuries coded as AIS 3 or more. We were able to identify 7 cases (4%) where initial clinical examination and imaging failed to detect either bleeding (pleural space or abdomen) or a pneumothorax. A further 5 cases were potential missed injuries, but the data were incomplete making confident inclusion in this group impossible. CONCLUSIONS Occult injuries are reported to have an incidence of around 2–5%. Serial imaging in the resuscitation room may enable early identification of chest and abdominal injuries. However, only 12 cases were identified making interpretation of suitable candidates for repeat imaging difficult. The question is which group of patients would benefit from planned repeat imaging before leaving the

    Loss of abdominal domain is a common problem in intestinal transplantation. Several surgical options are available perioperatively for abdominal wall reconstruction. This study reports the management and complications for intestinal transplant patients with abdominal wall closure either primarily or with foreign material. This single center study reviews the records of intestinal transplant patients between 2004 and 2010. Study outcomes included reoperation for dehiscence, hernia or enterocutaneous fistula. There were 37 of 146 patients (25%) who required implantation of foreign material at transplant. Of these 37, 30 (81%) had implantation of acellular dermal allograft (ADA) and 7 (19%) implantation of another mesh. Perioperative dehiscence was rare with 2/109 (2%) for primary closure, 0/30 (0%) for ADA and 1/7 (14%) for other mesh. There were 12/146 (8%) patients who underwent ventral hernia repair: primary closure 7/109 (6%), ADA 3/30 (10%) and other mesh 2/7 (28%). There were 4/146 (3%) patients who required surgery for enterocutaneous fistulas: 2/109 (2%) primary closure, 1/30 (3%) ADA and 1/7 (14%) synthetic mesh. Abdominal wall reconstruction with ADA biologic mesh provides an expeditious means of performing a tension-free closure of the fascial layer after intestinal transplantation with complications similar to those seen for primary closure.

    We briefly outline the history of hernia surgery development from the Ebers Papyrus to modern prosthetic repairs. The rapid evolution of anatomical, physiological and pathogenetic concepts has involved the rapid evolution of surgical treatments. From hernia sack cauterization to sack ligation, posterior wall repair (Bassini), and prosthetic reinforcement there has been an evident improvement in surgical treatment results that has stimulated surgeons to find new technical solutions over time. The introduction of prosthetic repair, the laparoscopic revolution, the impact of local anesthesia and the diffusion of day surgery have been the main advances of the last 50 years. Searching for new gold standards, the introduction of new devices has also led to new complications and problems. Research of the last 10 years has been directed to overcome prosthetic repair complications, introducing every year new meshes and materials. Lightweight meshes, composite meshes and biologic meshes are novelties of the last few years. We also take a look at future trends. PMID:24380545

    Background: Preclinical studies have demonstrated that macroporous silk fibroin protein scaffolds are capable of promoting physiologically durable supportive tissue, which favors application of these engineered tissues for clinical implantation. The safety and effectiveness of a long-lasting, transitory, 510(k)-cleared purified silk fibroin biologic scaffold (SBS) are investigated for soft-tissue support and repair of the abdominal wall. Methods: We conducted a multicenter retrospective review of all consecutive patients who underwent abdominal wall soft-tissue reinforcement with an SBS device between 2011 and 2013. Indications, comorbid conditions, surgical technique, complications, and outcomes were evaluated. Results: We reviewed the records of 172 consecutive patients who received an SBS for soft-tissue support. Of those, 77 patients underwent abdominal wall fascial repair, with a mean follow-up of 18.4 ± 7.5 months. Procedures using an SBS included reinforcement of an abdominal-based flap donor site (31.2%), ventral hernia repair (53.2%), and abdominoplasty (15.6%). The overall complication rate was 6.5%, consisting of 2 wound dehiscences, 1 with device exposure, 1 seroma, 1 infection with explantation, and a perioperative bulge requiring reoperation. There were no reports of hernia. Conclusions: Postoperative complication rates after 18 months were low, and most surgical complications were managed nonoperatively on an outpatient basis without mesh removal. To our knowledge, this is the only series to report on a long-lasting, transitory SBS for abdominal wall repair and reinforcement. Procedure-specific outcome studies are warranted to delineate optimal patient selection and define potential device characteristic advantages. PMID:25506529

    Splenosis is a common benign condition that occurs after splenic rupture via trauma or surgery. The mechanism behind splenic cell autotransplantation begins with the splenic rupture, either from trauma or surgical removal. Splenosis is usually found incidentally and, unless symptomatic, surgical therapy is not indicated. Subcutaneous splenosis is an extremely rare form of splenosis, mostly observed in abdominal surgical scars. We report a case of subcutaneous splenosis, as well as a comprehensive review of the literature. In our case, a 43-year-old woman who had splenectomy after traumatic splenic rupture at the age of 7 years old presented for plastic reconstruction of her postoperative scar. Upon surgery, two asymptomatic subcutaneous nodules were incidentally discovered. The presence of splenic tissue was confirmed by the histological study. The nodules were not excised, as the patient was not symptomatic. PMID:23401837

    The aim of this study was to describe specific histological findings of the Coxiella burnetii-infected aneurysmal abdominal aortic wall. Tissue samples of the aneurysmal abdominal aortic wall from seven patients with chronic Q fever and 15 patients without evidence of Q fever infection were analysed and compared. Chronic Q fever was diagnosed using serology and tissue PCR analysis. Histological sections were stained using haematoxylin and eosin staining, Elastica van Gieson staining and immunohistochemical staining for macrophages (CD68), T lymphocytes (CD3), T lymphocyte subsets (CD4 and CD8) and B lymphocytes (CD20). Samples were scored by one pathologist, blinded for Q fever status, using a standard score form. Seven tissue samples from patients with chronic Q fever and 15 tissue samples from patients without Q fever were collected. Four of seven chronic Q fever samples showed a necrotizing granulomatous response of the vascular wall, which was characterized by necrotic core of the arteriosclerotic plaque (P = 0.005) and a presence of high numbers of macrophages in the adventitia (P = 0.007) distributed in typical palisading formation (P = 0.005) and surrounded by the presence of high numbers of T lymphocytes located diffusely in media and adventitia. Necrotizing granulomas are a histological finding in the C. burnetii-infected aneurysmal abdominal aortic wall. Chronic Q fever should be included in the list of infectious diseases with necrotizing granulomatous response, such as tuberculosis, cat scratch disease and syphilis. PMID:24953727

    Background Endometriosis can be intrapelvic or, rarely, extrapelvic. Endometriosis involving the rectus abdominis muscle on the trocar port site is a rare event; until now, only 16 cases have been reported in the literature. The majority of cases were associated with previous abdominal surgery such as diagnostic laparoscopy, cyst excision, appendectomy, myomectomy, or cholecystectomy. We review all the reported cases of this unusual form of extrapelvic endometriosis. Case Report We report a new case of abdominal wall endometriosis at the trocar port site in the rectus abdominis muscle in a woman who had undergone 2 laparoscopies for endometriosis in the 3 years before coming to our attention. The diagnosis was made by sonography. We performed a surgical resection of the lesion with a free macroscopic margin of 5-10 mm. Conclusion Endometriosis should be considered in the differential diagnosis of any abdominal swelling. In our experience, surgery is the treatment of choice. PMID:26412997

We also reviewed all papers with the search terms 'IAH', 'IAP' and 'ACS' over the last three years, only extracting those papers which showed a novel approach in the non-surgical management of IAH and ACS.IAH and ACS are associated with increased morbidity and mortality. Non-surgical management is an important treatment option in critically ill patients with raised IAP. There are five medical treatment options to be considered to reduce IAP: 1) improvement of abdominal wall compliance; 2) evacuation of intra-luminal contents; 3) evacuation of abdominal fluid collections; 4) optimisation of fluid administration; and 5) optimisation of systemic and regional perfusion. This paper will review the first three treatment arms of the WSACS algorithm: abdominal wall compliance; evacuation of intra-luminal contents and evacuation of abdominal fluid collections. Emerging medical treatments will be analysed and finally some alternative specific treatments will be assessed. Other treatment options with regard to optimising fluid administration and systemic and regional perfusion will be described elsewhere, and are beyond the scope of this review. Medical management of critically ill patients with raised IAP should be instigated early to prevent further organ dysfunction and to avoid progression to ACS. Many treatment options are available and are often part of routine daily management in the ICU (nasogastric, rectal tube, prokinetics, enema, sedation, body position). Some of the newer treatments are very promising options in specific patient populations with raised IAP. Future studies are warranted to confirm

    Recently, a novel observation was made in which nonischemic trauma at a site remote from the heart produced by a transverse abdominal incision resulted in a marked reduction of infarct size (IS) in the mouse heart via activation of sensory nerve fibers in the skin and subsequent activation of bradykinin 2 receptors (BK2R). This phenomenon was termed remote preconditioning of trauma (RPCT). Since RPCT may have potential clinical implications we attempted to confirm these findings in a large animal model, the dog. The epoxyeicosatrienoic acids (EETs) have also recently been shown to be antinociceptive and have been shown to mimic ischemic preconditioning (IPC) and postconditioning (POC) in dogs, therefore, we tested the role of the EETs in RPCT. Anesthetized adult mongrel dogs of either sex were subjected to 60 min of left anterior descending (LAD) coronary artery occlusion followed by 3 h of reperfusion. In all groups except the controls (no slit), a transverse slit (9 cm) was applied to the abdominal wall of the dog being careful to only slit the skin. Subsequently, 15 min after the slit the heart was subjected to the ischemia/reperfusion protocol. In the control dogs, the IS as a percent of the area at risk (AAR) was 22.5 ± 2.4%, whereas in the dogs subjected to the slit alone the IS/AAR was reduced to 9.2 ± 1.2% (*P<0.01). The BR2R blocker, HOE 140 (50 ug/kg, iv) given 10 min prior to the slit, completely abolished the protective effects of RCPT as did pretreatment with 14,15-EEZE, a putative EET receptor blocker or pretreatment with the selective EET synthesis inhibitor, MSPPOH. These results suggest that BK and the EETs share cardioprotective properties in a large animal model of RPCT. PMID:21786213

    The purpose of this study was to determine the value of magnetic resonance imaging (MRI) for characterization of indeterminate spleen lesions in primary computed tomography (CT) of patients with blunt abdominal trauma. Twenty-five consecutive patients (8 female, 17 male, mean age 51.6 ± 22.4 years) with an indeterminate spleen lesion diagnosed at CT after blunt abdominal trauma underwent MRI with T2- and T1-weighted images pre- and post-contrast material administration. MRI studies were reviewed by two radiologists. Age, gender, injury mechanism, injury severity score (ISS), management of patients, time interval between CT and MRI, and length of hospital stay were included into the analysis. Patient history, clinical history, imaging, and 2-month clinical outcome including review of medical records and telephone interviews served as reference standard. From the 25 indeterminate spleen lesions in CT, 11 (44 %) were traumatic; nine (36 %) were non-traumatic (pseudocysts, n=5; hemangioma, n=4) and five proven to represent artifacts in CT. The ISS (P<0.001) and the length of hospital stay (P=0.03) were significantly higher in patients with spleen lesions as compared with those without. All other parameters were similar among groups (all, P>0.05). The MRI features ill-defined lesion borders, variable signal intensity on T1- and T2-weighted images depending on the age of the hematoma, focal contrast enhancement indicating traumatic pseudoaneurysm, perilesional contrast enhancement, and edema were most indicative for traumatic spleen lesions. As compared with CT (2/25), MRI (5/25) better depicted thin subcapsular hematomas as indicator of traumatic spleen injury. In conclusion, MRI shows value for characterizing indeterminate spleen lesions in primary CT after blunt abdominal trauma.

    AIM: To employ, in such conditions, a biological graft such as bovine pericardium that offers resistance to infection. METHODS: In our surgical department, from January 2006 to June 2010, 48 patients underwent abdominal wall reconstruction using acellular bovine pericardium; of these 34 patients had a contaminated wound due to diffuse peritonitis (complicated diverticulitis, bowel perforation, intestinal infarction, strangled hernia, etc.) and 14 patients had hernia relapse on infected synthetic mesh. RESULTS: In our series, one patient died of multi-organ failure 3 d after surgery. After placement of the pericardium mesh four cases of hernia relapse occurred. CONCLUSION: Recurrence rate is similar to that of prosthetic mesh repair and the application of acellular bovine pericardium (Tutomesh®, Tutogen Medical Gmbh Germany) is moreover a safe and feasible option that can be employed to manage complicated abdominal wall defects where prosthetic mesh is unsuitable.

    Trichobezoar represents a mass of swallowed hair inside the stomach. Here we report a 17-year-old girl who presented in our department with symptoms of gastric ulcer. Ultrasound examination followed by upper endoscopy revealed a large trichobezoar in the stomach with simultaneous gastric perforation. Laparoscopy also revealed a penetration into the anterior abdominal wall accompanied by abscess at this level. We performed a laparoscopic gastrotomy with trichobezoar extraction and laparoscopic treatment of perforation and abdominal wall abscess. The postoperative evolution was normal and the patient was discharged on the fifth postoperative day. We show that laparoscopic approach may be safely used in the treatment of the large gastric complicated trichobezoar. Several laparoscopic approaches were described for the treatment of tricobezoar and its complications but as far as we know this is the first report of laparoscopic treatment of large tricobezoar and associate gastric perforation.

    In female patients presenting a tumor of the lower abdominal wall especially after cesarian section, an endometriotic tumor as well as an aggressive desmoid tumor should be considered. Symptoms in correlation with the monthly period can facilitate the presurgical differentiation between endometriosis and fibromatosis. Ultrasound reveals the typical location of both tumors and its remarkable sonographic appearance. In the clinical practice, the desmoid fibromatosis of the lower abdominal wall is a very rare disease. We present a case of a 25-year-old pregnant and discuss diagnostic and therapeutic options by a PubMed literature review. With the knowledge of the prognosis of the desmoid fibromatosis and the respective treatment options including wait and see, complete surgical resection with macroscopically free margins and adjuvant approaches is essential to avoid further interventions and progression of the locally destructive tumor.

    Vesicouterine fistula (VUF) is a rare type of genitourinary fistula. Lower-segment cesarean section is the leading cause of VUF. Patients mostly present with the classical triad of menouria, amenorrhea, and urinary incontinence, with the history of a previous cesarean section. Conservative management with catheterization and open, laparoscopic, and robotic surgeries are the prescribed treatment options. We present the case of a 35-year-old woman who presented with cyclical menouria and urinary incontinence. After diagnosis of VUF by cystoscopy, the laparoscopic approach was chosen. During the procedure, we used anterior abdominal wall peritoneum and adjacent adipose tissue interposition for the first time, instead of omental interposition, because of the unavailability of omentum. The postoperative period was uneventful, and the procedure was successful. In conclusion, the laparoscopic approach is feasible and the anterior abdominal wall peritoneal flap can be used instead of omentum for tissue interposition when the omentum is not available.

    The changes in the evolution of the spatial and temporal distribution of the wall shear stresses (WSS) and gradients of wall shear stresses (GWSS) at different stages of the enlargement of an abdominal aortic aneurysm (AAA) are important in understanding the aetiology and progression of this vascular disease since they affect the wall structural integrity, primarily via the changes induced on the shape, functions and metabolism of the endothelial cells. Particle image velocimetry (PIV) measurements were performed in in vitro aneurysm models, while changing their geometric parameters systematically. It has been shown that, even at the very early stages of the disease, i.e. increase in the diameter ≤ 50%, the flow separates from the wall and a large vortex ring, usually followed by internal shear layers, is created. These lead to the generation of WSS that drastically differ in mean and fluctuating components from the healthy vessel. Inside the AAA, the mean WSS becomes negative along most of the aneurysmal wall and the magnitude of the WSS can be as low as 26% of the value in a healthy abdominal aorta.

    Introduction Here, we report the surgical excision of the urachal remnant using the abdominal wall-lift laparoscopy with a camera port in the umbilicus, combined with a small Pfannenstiel incision to optimally treat the bladder apex. Presentation of case A 21-year-old woman presented with periumbilical discharge and pain on urination. Contrast enhanced CT and MRI showed an abscess in the umbilical region that was connected to the bladder via a long tube-like structure. It was diagnosed as an infected urachal sinus. Partial excision of the umbilical fossa followed by dissection of the urachal remnant was easily performed using the abdominal wall-lift laparoscopy from the umbilicus down to the bladder without pneumoperitoneum or additional trocar placement. A Pfannenstiel incision was made above the pubis to get access to the junction between the urachal remnant and the bladder. Under direct vision, we succeeded in accurately dividing the remnant tract, and we adequately closed the bladder opening with absorbable sutures. This method has the advantage of easily closing peritoneal defects after excision of the urachal remnant with direct sutures under a laparoscopic view from the umbilicus. Cosmetic satisfaction was obtained postoperatively. Discussion and conclusion Urachal sinus excision using the abdominal wall-lift laparoscopy seems to surpass the previously reported methods in term of safety, cosmetics, and adequacy of surgical procedures.

    Patients with complex ventral/incisional hernias often undergo an abdominal wall reconstruction (AWR). These operations have a high cost of care and often result in a long hospital stay and high complication rates. Using the principles of clinical quality improvement (CQI), several attempts at process improvement were implemented in one hernia program over a 3-year period. For consecutive cases of patients undergoing abdominal wall reconstruction, process improvement attempts included the use of a long-term resorbable synthetic mesh (TIGR® Resorbable Matrix, Novus Scientific, Uppsala, Sweden) in place of a biologic mesh, the use of the transversus abdominis release approach in place of an open or endoscopic component separation (external oblique release) technique, and the use of a preoperative transversus abdominis plane (TAP) block using a long-acting local anesthetic (Exparel®, Pacira Pharmaceutical, Parsippany, NJ) as a part of perioperative multi-modal pain management and an enhanced recovery program. After over 60 cases, improvement in materials costs and postoperative outcomes were documented. No mesh-related complications occurred and no mesh removal was required. In this real-world, value-based application of CQI, several attempts at process improvement led to decreased costs and improved outcomes for patients who underwent abdominal wall reconstruction for complex ventral/incisional hernias. Value-based CQI could be a tool for improved health care value globally.

    Introduction Laparoscopic repair is becoming an increasingly popular alternative in the treatment of abdominal wall hernias. In spite of numerous studies evaluating this technique, indications for laparoscopic surgery have not been established. Similarly, implant selection and fixation techniques have not been unified and are the subject of scientific discussion. Aim To assess whether there is a consensus on the management of the most common ventral abdominal wall hernias among recognised experts. Material and methods Fourteen specialists representing the boards of European surgical societies were surveyed to determine their choice of surgical technique for nine typical primary ventral and incisional hernias. The access method, type of operation, mesh prosthesis and fixation method were evaluated. In addition to the laparoscopic procedures, the number of tackers and their arrangement were assessed. Results In none of the cases presented was a consensus of experts obtained. Laparoscopic and open techniques were used equally often. Especially in the group of large hernias, decisions on repair methods were characterised by high variability. The technique of laparoscopic mesh fixation was a subject of great variability in terms of both method selection and the numbers of tackers and sutures used. Conclusions Recognised experts have not reached a consensus on the management of abdominal wall hernias. Our survey results indicate the need for further research and the inclusion of large cohorts of patients in the dedicated registries to evaluate the results of different surgical methods, which would help in the development of treatment algorithms for surgical education in the future.

    Complex examination and treatment of 120 patients with anatomo-functional insufficiency of the abdominal wall was made after operations on organs of the abdominal cavity and retroperitoneal space. In the 1st group (60 patients) the abdominal wall was sutured by traditional methods. In the 2nd group (60 patients) laparotomy was followed by implantation of polypropylene endoprosthesis by over-aponeurotic method, and suturing of the lateral wall--by sub-aponeurotic method. At the long-term postoperative period the postoperative ventral hernias were formed in 21.6% of patients of the 1st group, in the 2nd group of patients hernias were not detected. Physical component of quality of life of the 2nd group was 1.5 times, and mental component 1.7 times higher than in the 1st group.

    This paper focuses on 63 cases of syndrome of nonprimary acute abdomen (SNPAA) in craniocerebral injury (CCI) sustained in the state of alcoholic intoxication, and 59 observations connected with cranio-abdominal injuries (CAI). In the presence of cerebral injuries, one of the specific characteristics of alcohol was that it entailed changes in the abdominal symptomatology either concealing manifestations of severe damage to the abdominal organs or potentiating SNPAA. In all the observations the abdominal symptomatology was less pronounced that in those victims who do not take alcoholic drinks. There have been identified four variants of SNPAA course. In 12.7% of cases manifestations of the above syndrome were related to the CCI pattern only, being associated with origination of pseudodefense of "truncal" genesis. It is advisable that instrumental methods of study into abdominal organs should come to be more widely used in those settings where there is alcohol intoxication with suspected CAI.

    Abdominal aortic aneurysm (AAA) is a vascular disease involving the gradual dilation of the abdominal aorta. It has been reported that development of AAA is associated with inflammation of the vascular wall; however, the mechanism of AAA rupture is not fully understood. In this study, we investigated the mechanism underlying AAA rupture using a hypoperfusion-induced animal model. We found that the administration of triolein increased the AAA rupture rate in the animal model and that the number of adipocytes was increased in ruptured vascular walls compared to non-ruptured walls. In the ruptured group, macrophage infiltration and the protein levels of matrix metalloproteinases 2 and 9 were increased in the areas around adipocytes, while collagen-positive areas were decreased in the areas with adipocytes compared to those without adipocytes. The administration of fish oil, which suppresses adipocyte hypertrophy, decreased the number and size of adipocytes, as well as decreased the risk of AAA rupture ratio by 0.23 compared to the triolein administered group. In human AAA samples, the amount of triglyceride in the adventitia was correlated with the diameter of the AAA. These results suggest that AAA rupture is related to the abnormal appearance of adipocytes in the vascular wall. PMID:27499372

    Finite element wall stress simulations on patient-specific models of abdominal aortic aneurysm (AAA) may provide a better rupture risk predictor than the currently used maximum transverse diameter. Calcifications in the wall of AAA lead to a higher maximum wall stress and thus may lead to an elevated rupture risk. The reported material properties for calcifications and the material properties actually used for simulations show great variation. Previous studies have focused on simplified modelling of the calcification shapes within a realistic aneurysm shape. In this study we use an accurate representation of the calcification geometry and a simplified model for the AAA. The objective of this approach is to investigate the influence of the calcification geometry, the material properties and the modelling approach for the computed peak wall stress. For four realistic calcification shapes from standard clinical CT images of AAA, we performed simulations with three distinct modelling approaches, at five distinct elasticity settings. The results show how peak wall stress is sensitive to the material properties of the calcifications. For relatively elastic calcifications, the results from the different modelling approaches agree. Also, for relatively elastic calcifications the computed wall stress in the tissue surrounding the calcifications shows to be insensitive to the exact calcification geometry. For stiffer calcifications the different modelling approaches and the different geometries lead to significantly different results. We conclude that an important challenge for future research is accurately estimating the material properties and the rupture potential of the AAA wall including calcifications.

    As a degenerative and inflammatory desease of elderly patients, about 80% of abdominal aortic aneurysms (AAA) show considerable wall calcification. Effect of calcifications on computational wall stress analyses of AAAs has been rarely treated in literature so far. Calcifications are heterogeneously distributed, non-fibrous, stiff plaques which are most commonly found near the luminal surface in between the intima and the media layer of the vessel wall. In this study, we therefore investigate the influence of calcifications as separate AAA constituents on finite element simulation results. Thus, three AAAs are reconstructed with regard to intraluminal thrombus (ILT), calcifications and vessel wall. Each patient-specific AAA is simulated twice, once including all three AAA constituents and once neglecting calcifications as it is still common in literature. Parameters for constitutive modeling of calcifications are thereby taken from experiments performed by the authors, showing that calcifications exhibit an almost linear stress-strain behavior with a Young's modulus E ≥ 40 MPa. Simulation results show that calcifications exhibit significant load-bearing effects and reduce stress in adjacent vessel wall. Average stress within the vessel wall is reduced by 9.7 to 59.2%. For two out of three AAAs, peak wall stress decreases when taking calcifications into consideration (8.9 and 28.9%). For one AAA, simulated peak wall stress increases by 5.5% due to stress peaks near calcification borders. However, such stress singularities due to sudden stiffness jumps are physiologically doubtful. It can further be observed that large calcifications are mostly situated in concavely shaped regions of the AAA wall. We deduce that AAA shape is influenced by existent calcifications, thus crucial errors occur if they are neglected in computational wall stress analyses. A general increase in rupture risk for calcified AAAs is doubted.

    Permacol mesh has shown promise when used in abdominal wall repair, especially in the presence of a contaminated surgical field. This biomaterial, derived from porcine dermis collagen, has proposed advantages over synthetic materials due to increased biocompatibility and reduced foreign body reaction within human tissues. However, we present a case report describing a patient who displayed rejection to a Permacol mesh when used in the repair of abdominal wound dehiscence following an emergency laparotomy. Review of the English language literature using PubMed and Medline, showed only two previously published cases of explantation of Permacol due to sepsis or wound breakdown. The authors believe this is the first case of severe foreign body reaction leading to rejection of Permacol. Both animal and human studies show conflicting evidence of biocompatibility. There are several reports of successful use of Permacol to repair complex incisional herniae or abdominal walls in the presence of significant contamination. It appears from the literature that Permacol is a promising material, but as we have demonstrated, it has the potential to evoke a foreign body reaction and rejection in certain subjects.

    Abdominal aortic aneurysm (AAA) rupture is believed to occur when the mechanical stress acting on the wall exceeds the strength of the wall tissue. In endovascular aneurysm repair, a stent-graft in a catheter is released at the aneurysm site to form a new blood vessel and protect the weakened AAA wall from the pulsatile pressure and, hence, possible rupture. In this paper, we propose a framework to estimate the wall stress distribution of non-stented/stented AAA based on fluid-structure interaction, which is utilized in a surgical simulation system (IRAS). The 3D geometric model of AAA is reconstructed from computed tomography angiographic (CTA) images. Based on our experiments, a combined logarithm and polynomial strain energy equation is applied to model the elastic properties of arterial wall. The blood flow is modeled as laminar, incompressible, and non-Newtonian flow by applying Navier-Stokes equation. The obtained pressure of blood flow is applied as load on the AAA meshes with and without stent-graft and the wall stress distribution is calculated by fluid-structure interaction (FSI) solver equipped in ANSYS. Experiments demonstrate that our analytical results are consistent with clinical observations. PMID:22254456

    Abdominal aortic aneurysm wall distensibility can be estimated by measuring pulse pressure and the corresponding sac volume change, which can be obtained by measuring wall displacement. This approach, however, may introduce error if the role of thrombus in assisting the wall in bearing the pulse pressure loading is neglected. Our aim was to introduce a methodology for evaluating and potentially correcting this error in estimating distensibility. Electrocardiogram-gated computed tomography images of eleven patients were obtained, and the volume change between diastole and systole was measured. Using finite element procedures, we determined the equivalent pulse pressure loading that should be applied to the wall of a model where thrombus was digitally removed, to yield the same sac volumetric increase caused by applying the luminal pulse pressure to the model with thrombus. The equivalent instead of the measured pulse pressure was used in the distensibility expression. For a relative volumetric thrombus deposition (V ILT) of 50 %, a 62 % distensibility underestimation resulted when thrombus role was neglected. A strong linear correlation was observed between distensibility underestimation and V ILT. To assess the potential value of noninvasive wall distensibility measurement in rupture risk stratification, the role of thrombus on wall loading should be further investigated. PMID:25548097

    Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. We describe here for the first time a patient with a huge GIST of the abdominal wall without any relation to the gastrointestinal tract, omentum, or mesentery. With regard to the size of 24 cm and a low mitotic index, this GIST is considered an intermediate risk for metastasis. Radical surgical resection was performed with negative pathologic resection margins. The classic immunohistochemical phenotype of the tumor described facilitates the differential diagnosis to exclude abdominal desmoid tumor and solitary fibrous tumor (SFT). In the case of metastasis, therapeutic nihilism no longer seems justified with the availability of imatinib, a tyrosine kinase inhibitor, which shows encouraging results in the therapy of metastatic GIST.

    The primo vascular system (PVS) is being established as a circulatory system that corresponds to acupuncture meridians. There have been two critical questions in making the PVS accepted as a novel liquid flowing system. The first one was directly to show the flow of liquid in PVS and the second one was to explain why it was not observed in the conventional histological study of animal tissues. Flow in the PVS in the abdominal cavity was previously verified by injecting Alcian blue into a primo node. However, the tracing of the dye to other subsystems of the PVS has not been done. In the current work we injected fluorescent nanoparticles (FNPs) into a primo node and traced them along a primo vessel which was inside a fat tissue in the abdominal wall. Linea alba is a white middle line in the abdominal skin of a mammal and a band of fat tissue is located in parallel to the linea alba in the parietal side of the abdominal wall of a rat. In this fat band a primo vessel runs parallel to the prominent blood vessels in the fat band and is located just inside the parietal peritoneum. About the second question on the reason why the PVS was not in conventional histological study the current work provided the answer. Histological analysis with hematoxyline and eosine, Masson's trichrome, and Toluidine blue could not discriminate the primo vessel even when we knew the location of the PVS by the trace of the FNPs. This clearly explains why the PVS is hard to observe in conventional histology: it is not a matter of resolution but the contrast. The PVS has very similar structure to the connective tissues that surround the PVS. In the current work we propose a method to find the PVS: Observation of mast cell distribution with toluidine blue staining and the PN has a high density of mast cells, while the lymph node has low density.

    The goal of abdominal wall reconstruction is to restore and maintain abdominal domain. A PubMed(R) review of the literature (including "old" MEDLINE through February 2007) suggests that bioprosthetic materials are increasingly used to facilitate complex abdominal wall reconstruction. Reported results (eight case reports/series involving 137 patients) are encouraging. The most commonly reported complications are wound seroma (18 patients, 13%), skin dehiscence with graft exposure without herniation (six, 4.4%), superficial and deep wound infections (five, 3.6%), hernia recurrence (four, 2.9%), graft failure with dehiscence (two), hematoma (two), enterocutaneous fistula (one), and flap necrosis (one). Two recent cases are reported herein. In one, a 46-year-old woman required open abdominal management after gastric remnant perforation following a Roux-en-Y gastric bypass procedure. Porcine dermal collagen combined with cutaneous flaps was used for definitive abdominal wall reconstruction. The patient's condition improved postoperatively and she was well 5 months after discharge from the hospital. In the second, a 54-year-old woman underwent repair of an abdominal wall defect following resection of a large leiomyosarcoma. Human acellular dermis combined with myocutaneous flaps was used to reconstruct the abdominal wall defect. The patient's recovery was uncomplicated and 20 weeks following surgery she was doing well with no evidence of recurrence or hernia. The results reported to date and the outcomes presented here suggest that bioprosthetic materials are safe and effective for repair of large abdominal wall defects. Prospective, randomized, controlled studies are needed to compare the safety and efficacy of other reconstructive techniques as well as human and porcine dermal-derived bioprostheses.

    Purpose: Preoperative external-beam radiation therapy (preop RT) in the management of Retroperitoneal Liposarcomas (RPLS) typically involves the delivery of radiation to the entire tumor mass: yet this may not be necessary. The purpose of this study is to evaluate a new strategy of preop RT for RPLS in which the target volume is limited to the contact area between the tumoral mass and the posterior abdominal wall. Methods and Materials: Between June 2000 and Jan 2005, 18 patients with the diagnosis of RPLS have been treated following a pilot protocol of pre-op RT, 50 Gy in 25 fractions of 2 Gy/day. The Clinical Target Volume (CTV) has been limited to the posterior abdominal wall, region at higher risk for local relapse. A Three-Dimensional conformal (3D-CRT) and an Intensity Modulated (IMRT) plan were generated and compared; toxicity was reported following the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events v3.0. Results: All patients completed the planned treatment and the acute toxicity was tolerable: 2 patients experienced Grade 3 and 1 Grade 2 anorexia while 2 patients developed Grade 2 nausea. IMRT allows a better sparing of the ipsilateral and the contralateral kidney. All tumors were successfully resected without major complications. At a median follow-up of 27 months 2 patients developed a local relapse and 1 lung metastasis. Conclusions: Our strategy of preop RT is feasible and well tolerated: the rate of resectability is not compromised by limiting the preop CTV to the posterior abdominal wall and a better critical-structures sparing is obtained with IMRT.

    A total of 307 cases of fatal car injuries with traumas of the abdominal organs are analyzed. There were three types of injuries: those caused by collision of a pedestrian with a moving car (96 cases) injuries inflicted inside a car cabin (n = 157), and inflicted by a car wheel crossing the body (n = 54). Differences in the injuries inflicted in different types of car traumas are described. The authors demonstrate the possibility of differential diagnosis of these types of traumas in cases when the circumstances of the accident are unknown. They offer a differential diagnostic table for practical use, based on their findings.

    Heavy metals are able to interfere with the function of vital cellular components. Besides in trace heavy metals, which are essential at low concentration for humans, there are heavy metals with a well-known toxic and oncogenic potential. In this study, for the first time in literature, we report the unique adulthood case of an atypical primitive neuroectodermal tumor of the abdominal wall, diagnosed by histology and immunohistochemistry, with the molecular hybridization support. The neoplasia occurred in a patient chronically exposed to a transdermal delivery of heavy metal salts (aluminum and bismuth), whose intracellular bioaccumulation has been revealed by elemental microanalysis.

    Port-wine stains (PWSs), or capillary malformations, are common congenital lesions, but acquired lesions rarely present in the setting of trauma. We present the case of an 18-year-old man who developed a PWS and associated localized eczema following penetrating trauma to the left abdomen. The diagnoses were confirmed on biopsy. The patient's eczema improved with topical steroids. Magnetic resonance imaging of PWSs is recommended in order to rule out deeper arteriovenous malformations. More research is needed to elucidate the connection between PWS pathophysiology and the development of eczema.

    Most frequent cause of abnormalities of elastic properties of walls of abdominal aorta is development of atherosclerosis resulting in replacement of elastin by simpler fibrillar proteins and collagen. This subsequently leads to dilation of the aorta and formation of aneurism. Increase of collagen content in the aortic wall correlates with growth of aneurism dimensions. Main method of treatment of aneurisms is implantation of abdominal aortic prosthesis. Detailed preoperative assessment of functional state of the aortic wall is necessary in preoperative period but none of modern imaging instrumental methods including ultrasound study allows to realize this assessment. In this article we present first experience of assessment of aortic wall deformation velocity analyzing results of ultrasound study with the help of the Multivox working station in 36 patients 16 of whom were operated because of aneurism of abdominal aorta.

    Perforators flaps take a special place in reconstructive surgery. These flaps can be dissected and turned as a propeller blade on its pedicule axis. We report the case of a 54-year-old man presenting a recurrence of a dermatofibrosarcoma in the right hypochondrium. Tumor resection caused a large abdominal wall defect taking the anterior aponeurosis of the rectus abdominis. An angioscanner was realized in preoperative to locate the perforators of the deep superior epigastric artery. We realized a propeller flap based on a perforator of the left superior epigastric artery who allowed to cover the wall defect. We set up a patch of Vicryl® to reconstruct the aponeurosis plan at the same operative time. We didn't note any necrosis and complete healing occurred in 2 weeks. The margins were healthy. The cosmetic result and the low morbidity make this flap a good therapeutic option. This flap seems reliable, arteries perforators are constant with good diameter.

    Objective: The laparoscopic treatment of eventrations and ventral hernias has been little used, although these hernias are well suited to a laparoscopic approach. The objective of this study was to investigate the usefulness of a laparoscopic approach in the surgical treatment of ventral hernias. Methods: Between January 1994 and July 1998, a series of 100 patients suffering from major abdominal wall defects were operated on by means of laparoscopic techniques, with a mean postoperative follow-up of 30 months. The mean number of defects was 2.7 per patient, the wall defect was 93 cm2 on average. There were 10 minor hernias (<5 cm), 52 medium-size hernias (5-10 cm), and 38 large hernia (>10 cm). The origin of the wall defect was primary in 21 cases and postsurgical in 79. Three access ports were used, and the defects were covered with PTFE Dual Mesh measuring 19 × 15 cm in 54 cases, 10 x 15 cm in 36 cases, and 12 × 8 cm in 10 cases. An additional mesh had to be added in 21 cases. In the last 30 cases, PTFE Dual Mesh Plus with holes was employed. Results: Average surgery time was 62 minutes. One procedure was converted to open surgery, and only one patient required a second operation in the early postoperative period. Minor complications included 2 patients with abdominal wall edema, 10 seromas, and 3 subcutaneous hematomas. There were no trocar site infections. Two patients developed hernia relapse (2%) in the first month after surgery and were reoperated with a similar laparoscopic technique. Oral intake and mobilization began a few hours after surgery. The mean stay in hospital was 28 hours. Conclusions: Laparoscopic technique makes it possible to avoid large incisions, the placement of drains, and produces a lower number of seromas, infections and relapses. Laparoscopic access considerably shortens the time spent in the hospital. PMID:10917121

    The abdominal wall is an important structure differentiating subcutaneous and visceral compartments and intimately involved with maintaining abdominal structure. Segmentation of the whole abdominal wall on routinely acquired computed tomography (CT) scans remains challenging due to variations and complexities of the wall and surrounding tissues. In this study, we propose a slice-wise augmented active shape model (AASM) approach to robustly segment both the outer and inner surfaces of the abdominal wall. Multi-atlas label fusion (MALF) and level set (LS) techniques are integrated into the traditional ASM framework. The AASM approach globally optimizes the landmark updates in the presence of complicated underlying local anatomical contexts. The proposed approach was validated on 184 axial slices of 20 CT scans. The Hausdorff distance against the manual segmentation was significantly reduced using proposed approach compared to that using ASM, MALF, and LS individually. Our segmentation of the whole abdominal wall enables the subcutaneous and visceral fat measurement, with high correlation to the measurement derived from manual segmentation. This study presents the first generic algorithm that combines ASM, MALF, and LS, and demonstrates practical application for automatically capturing visceral and subcutaneous fat volumes.

    The muscles of the infrapubic abdominal wall of crocodilians play an important role in their ventilatory mechanism. Yet the anatomy and homology of these muscles is poorly understood. To gain new insights into the anatomy of the crocodilian infrapubic abdominal wall, we dissected a specimen of Crocodylus niloticus. Origin and insertion of the muscles, as well as their arrangement relative to each other was examined in great detail. The findings were compared with those of other crocodilian taxa to detect potential variability of the muscles of interest. The homology of the muscles was studied by comparing the muscles of the crocodilian infrapubic abdominal wall with those of other diapsids. In Crocodylus niloticus, the infrapubic abdominal wall consists of four muscles: Musculus truncocaudalis, M. ischiotruncus, and Mm. rectus abdominis externus and internus. The arrangement of the muscles of the infrapubic abdominal wall of Crocodylus niloticus is consistent with that found in most other crocodilian taxa. In some crocodilian taxa, an additional muscle, M. ischiopubis, is found. In the remaining diapsids, only M. rectus abdominis is present. The crocodilian M. truncocaudalis, M. ischiotruncus and, if present, M. ischiopubis appear to be derivates of M. rectus abdominis; the development of those might be related to the evolution of the unique crocodilian ventilatory mechanism.

    Abdominal wall endometriosis (AWE) is a rare condition that usually develops in a surgical scar resulting from a Caesarean section. While commonly seen in the cutaneous and subcutaneous fat tissue at the Caesarean scar level, its intramuscular localization is quite rare. Its treatment options consist of the excision of the lesion and/or hormonal therapies, although wide surgical excision is the treatment of choice in the literature. Wide surgical excision may create a defect in the abdominal wall and may increase the risk of hernia formation and mesh complications. This case report describes the clinical and radiological findings and treatment modalities of endometriosis that have appeared in the rectus abdominis muscle of a 25-year-old patient at the Caesarean scar level. Sclerotherapy may be used for endometrioma. We present a new and alternative treatment method using ultrasound-guided intralesional ethanol injection for AWE. Compared with the complications of surgical excision, the complications of sclerotherapy by ethanol are at a more acceptable level. Sclerotherapy by ethanol injection may be an alternative treatment to surgery for AWE.

    Purpose Tissue adhesion is a well-known postsurgical phenomenon, causing pain, functional obstruction, and difficult reoperative surgery. To overcome these problems, various synthetic and natural polymer membranes have been developed as postoperative tissue adhesion barriers. However, limitation in their use has hindered its actual application. We prepared a hyaluronate membrane (HM) to evaluate its efficacy and safety as an adhesion barrier compared to a commercialized product (Interceed, Ethicon). Methods To evaluate the antiadhesion effect, a cecum-abdominal wall abrasion model was adopted in a rabbit. The denuded cecum was covered by Interceed or HM or neither and apposed to the abdominal wall (each, n = 10). Four weeks after surgery, the level of adhesion was graded. Acute and chronic toxicity of the three groups were also evaluated. Results Blood samples drawn to evaluate acute toxicity at postoperative day 3 and 7 showed no significant difference among the three groups. The grade and area of adhesion were significantly lower in the HM compared to those of the control and Interceed at four weeks after surgery. Histologic evaluations, which was carried out to estimate tissue reactions at the site of application, as well as to assess chronic toxicity for the major organs, were not significantly different in the three groups. Conclusion This study showed that the antiadhesion efficacy of HM was superior to commercialized antiadhesion membrane, Interceed. Low inflammatory response and nontoxicity were also demonstrated. From these results, we suggest that the HM is a good candidate as a tissue adhesion barrier. PMID:23908960

    The objective of this study was to determine the inter- and intra-examiner reliability of pain pressure threshold algometry at various points of the abdominal wall of healthy women. Twenty-one healthy women in menacme with a mean age of 28 ± 5.4 years (range: 19-39 years) were included. All volunteers had regular menstrual cycles (27-33 days) and were right-handed and, to the best of our knowledge, none were taking medications at the time of testing. Women with a diagnosis of depression, anxiety or other mood disturbances were excluded. Women with previous abdominal surgery, any pain condition or any evidence of inflammation, hypertension, smoking, alcoholism, or inflammatory disease were also excluded. Pain perception thresholds were assessed with a pressure algometer with digital traction and compression and a measuring capacity for 5 kg. All points were localized by palpation and marked with a felt-tipped pen and each individual was evaluated over a period of 2 days in two consecutive sessions, each session consisting of a set of 14 point measurements repeated twice by two examiners in random sequence. There was no statistically significant difference in the mean pain threshold obtained by the two examiners on 2 diferent days (examiner A: P = 1.00; examiner B: P = 0.75; Wilcoxon matched pairs test). There was excellent/good agreement between examiners for all days and all points. Our results have established baseline values to which future researchers will be able to refer. They show that pressure algometry is a reliable measure for pain perception in the abdominal wall of healthy women. PMID:22527127

    Reconstruction of large, complex defects of the abdominal wall after resection of malignant tumors can be challenging. The transfer of an anterolateral thigh (ALT) flap is a feasible and effective option. However, no report has been published on the use of ALT flap after metachronous colonic tumor resection so far. We present an original case of resection of metachronous carcinoma of rectum with reconstruction of the abdominal wall defect using an ALT flap harvested with its aponeurosis. The postoperative course was uncomplicated. Functional and esthetic results were satisfactory. There was no postoperative incisional hernia or tumor recurrence. We conclude that abdominal wall defects of large sizes can be successfully reconstructed using an appropriately designed ALT flap; a simple, single-stage effective reconstruction. PMID:27161142

    Various methods have been employed to reconstruct complex abdominal wall defects. Structural prosthetic materials such as polypropylene mesh and ePTFE (expanded polytetrafluoroethylene) have been widely used to close these large fascial defects, however, complications with infection and adhesions have led to the recent use of more biocompatible implants. Permacol (acellular porcine dermis) is used as a dermal scaffold, which eventually becomes vascularised and remodelled to reconstruct the abdominal wall in these complex patients. A retrospective review was performed of all patients who underwent consecutive abdominal wall reconstruction with Permacol at our institution in the year 2006. Twenty-eight patients were identified and included in our study. Factors evaluated were: body mass index, relevant co-morbidities, aetiology of hernia, hernia defect size based on CT scan and intraoperative measurement, size of Permacol implant, length of hospital stay, and postoperative complications. Surgical technique was standardised among six surgeons and involved a single layer of acellular porcine dermis as a subfascial 'underlay' graft under moderate tension upon maximal hernia reduction. Tissue expanders were not required for skin closure. Out of 28 patients, 12 were male and 16 were female. Mean intraoperative hernia size was 150 cm(2) (range of 10 cm(2) to 600 cm(2)). Mean age was 55 years with an average body mass index (BMI) of 34 (largest BMI of 61.4). Defects were attributed to either a previous laparotomy incision or open abdomen. Mean hospital stay was 9.67 days. At a mean follow-up of sixteen months, there were three recurrent hernias (10.7%) based on physical examination and postoperative CT scan evaluation. One patient developed a superficial wound dehiscence which was successfully treated with local wound care and one patient developed a cellulitis which was successfully treated with antibiotic therapy. Four patients (14.3%) developed a chronic, non

    Background Positive Focused Assessment with Sonography in Trauma (FAST) and hypotension often indicates urgent surgery. An abdomen/pelvis CT (apCT) may allow less invasive management but the delay may be associated with adverse outcomes. Methods Patients in the Prospective Observational Multicenter Major Trauma Transfusion study with hypotension and a positive FAST (HF+) who underwent a CT (apCT+) were compared to those who did not. Results Of the 92 HF+ identified, 32(35%) underwent apCT during initial evaluation and apCT was associated with decreased odds of an emergency operation, OR 0.11 95% CI (0.001–0.116) and increased odds of angiographic intervention, OR 14.3 95% CI (1.5–135). There was no significant difference in 30 day mortality or need for dialysis. Conclusion An apCt in HF+ patients is associated with reduced odds of emergency surgery, but not mortality. Select HF+ patients can safely undergo apCT to obtain clinically useful information. PMID:25805456

    Paralysis of the respiratory muscles in people with tetraplegia affects their ability to breathe and contributes to respiratory complications. Surface functional electrical stimulation (FES) of abdominal wall muscles can be used to increase tidal volume (V_{T}) and improve cough peak flow (CPF) in tetraplegic subjects who are able to breathe spontaneously. This study aims to evaluate the feasibility and effectiveness of a novel abdominal FES system which generates stimulation automatically, synchronised with the subjects' voluntary breathing activity. Four subjects with complete tetraplegia (C4-C6), breathing spontaneously, were recruited. The automatic stimulation system ensured that consistent stimulation was achieved. We compared spirometry during unassisted and FES-assisted quiet breathing and coughing, and measured the effect of stimulation on end-tidal CO_2 (EtCO_2) during quiet breathing. The system dependably recognised spontaneous respiratory effort, stimulating appropriately, and was well tolerated by patients. Significant increases in V_T during quiet breathing (range 0.05-0.23 L) and in CPF (range 0.04-0.49 L/s) were observed. Respiratory rate during quiet breathing decreased in all subjects when stimulated, whereas minute ventilation increased by 1.05-2.07 L/min. The changes in EtCO_2 were inconclusive. The automatic stimulation system augmented spontaneous breathing and coughing in tetraplegic patients and may provide a potential means of respiratory support for tetraplegic patients with reduced respiratory capacity.

    Echinococcus multilocularis causes infection where the most commonly affected organ is the liver, followed by the lung, kidney, bone and the brain. Other sites such as the heart, spleen, pancreas and soft tissues are very rarely affected. Surgical treatment combined with chemotherapy using various technical approaches remains the main therapeutic modality for echinococcal liver disease. To the best of our knowledge there are less than five clinical cases of cutaneous presentation of liver alveolar echinococcosis described. We present a unique case of liver echinococcosis presenting as recurrent abdominal wall fistula and abscess in a 29-year-old man. Diagnosis was based on CT imaging, serological analysis and histological findings from the fistula. Medical treatment with albendazole was initiated and liver resection was performed. The patient has no symptoms and signs of recurrence 1 year after operation, while still on albendazole therapy. This case description highlights the importance of early suspicion and treatment of unusual echinococcosis clinical presentations.

    Gross and histopathological features of surgically excised squamous cell carcinomas (SCC) observed in thirteen local Libyan ewes were reported. The age of the ewes enrolled in the current study ranged from 2 to 3 years. The cases were admitted to private veterinary clinics in south-western region of Tripoli, Libya, during the period between July 2014 and October 2015. All lesions were located in the right and left lateral abdominal wall (caudo-ventrally) with a size range of 8 to 11cm in diameter. The tumor masses have been removed by surgical excision. The histopathological examination of surgically excised masses has revealed the characteristic cell nests of SCC showing central keratinization and hyalinization with presence of apoptotic bodies, fattened keratinocytes, and a heavy interstitial infiltration of neutrophils and lymphocytes. The follow up of the cases showed no signs of tumor reoccurrence. In conclusion, SCC in Libyan sheep affects mainly the woolless areas and can be successfully removed by surgical excision.

    Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common monogenic disorders and the leading inheritable cause of end-stage renal disease worldwide. Cystic and noncystic extrarenal manifestations are correlated with variable clinical presentations so that an inherited disorder is now considered a systemic disease. Kidney and liver cystic infections are the most common infectious complications in ADPKD patients. Furthermore, it is well known that ADPKD is commonly associated with colonic diverticular disease which recently has been reported to be linked to increased risk of infection on hemodialysis patients. Herein, we present a case of anterior abdominal wall abscess caused by Enterococcus faecalis in a patient with ADPKD undergoing hemodialysis. Although the precise pathway of infection remains uncertain, the previous medical history as well as the clinical course of our patient led us to hypothesize an alternative route of infection from the gastrointestinal tract through an aberrant intestinal barrier into the bloodstream and eventually to an atypical location.

    Introduction Biological and synthetic laminar absorbable prostheses are available for the repair of hernia defects in the abdominal wall. They share the important feature of being gradually degraded in the host, resulting in place the formation of a neotissue. This study was designed to assess the host tissue’s incorporation of collagen bioprostheses and a synthetic absorbable prosthesis. Methods Partial defects were created in the abdominal walls of 72 New Zealand rabbits and repaired using collagen bioprostheses Tutomesh® and Strattice® or a synthetic prosthesis Bio-A®. Specimens were collected for light microscopy, collagens gene and protein expression, macrophage response and biomechanical resistance at 14, 30, 90 and 180 days post-implantation. Results Tutomesh® and Bio-A® were gradually infiltrated by the host tissue and almost completely degraded by 180 days post-implantation. In contrast, Strattice® exhibited material encapsulation, no prosthetic degradation and low cell infiltration at earlier timepoints, whereas at later study time, collagen deposition could be observed within the mesh. In the short term, Bio-A® exhibited higher level of collagen 1 and 3 mRNA expression compared with the two other biological prostheses, which exhibited two peaks of higher expression at 14 and 90 days. The expression of collagen III was homogeneous throughout the study and collagen I deposition was more evident in Strattice®. Macrophage response decreased over time in biomeshes. However, in the synthetic mesh remained high and homogeneous until 90 days. The biomechanical analysis demonstrated the progressively increasing tensile strength of all biomaterials. Conclusions The tissue infiltration of laminar absorbable prostheses is affected by the structure and composition of the mesh. The synthetic prosthesis exhibited a distinct pattern of tissue incorporation and a greater macrophage response than did the biological prostheses. Of all of the laminar, absorbable

    Traumatic injury of the pancreas is rare in children. It is often difficult to diagnose due to the lack of signs and symptoms, and shortly after trauma laboratory values may be normal. In addition, ultrasound and CT are often not specific. The treatment of grade 1 and 2 injury is non-operative. Although there seems to be a shift towards non-operative management of grade 3-5 injuries (with injury of the pancreatic duct), this is still a matter of debate. We describe 3 children, a girl of 2.5 years-old and a boy of 7 years-old, with grade 3 pancreatic injuries and an 8-year-old boy with a grade 2 injury. We demonstrate that the diagnosis is hard to establish, while the consequences of this injury can be serious. Thinking of pancreatic injury is most important to its diagnosis. We advocate referral to or consultation of specialized centres in these cases.

    We implanted stents in three patients who had traumatic abdominal aortic dissections, complicated by right limb ischemia in one case. The circulating false channel extended to the left iliac artery in one case and to both iliac arteries in the last case. Diagnosis and radiological follow-up included ultrasound, computed tomography, and arteriography. Two patients were treated with Wallstents, one with a Palmaz stent. The occlusion of the false channel was obtained in all patients without any significant residual stenosis. No early or late complication was noted in any of the patients. The longest follow-up was 2 years.We conclude that stent placement is an efficient method for the treatment of noniatrogenic inframesenteric aortic dissections.

    Although a variety of materials are currently used for abdominal wall repair, general complications encountered include herniation, infection, and mechanical mismatch with native tissue. An approach wherein a degradable synthetic material is ultimately replaced by tissue mechanically approximating the native state could obviate these complications. We report here on the generation of biodegradable scaffolds for abdominal wall replacement using a wet electrospinning technique in which fibers of a biodegradable elastomer, poly(ester urethane)urea (PEUU), were concurrently deposited with electrosprayed serum-based culture medium. Wet electrospun PEUU (wet ePEUU) was found to exhibit markedly different mechanical behavior and to possess an altered microstructure relative to dry processed ePEUU. In a rat model for abdominal wall replacement, wet ePEUU scaffolds (1 × 2.5 cm) provided a healing result that developed toward approximating physiologic mechanical behavior at 8 wks. An extensive cellular infiltrate possessing contractile smooth muscle markers was observed together with extensive extracellular matrix (collagens, elastin) elaboration. Control implants of dry ePEUU and expanded polytetrafluoroethylene did not experience substantial cellular infiltration and did not take on the native mechanical anisotropy of the rat abdominal wall. These results illustrate the markedly different in vivo behavior observed with this newly reported wet electrospinning process, offering a potentially useful refinement of an increasingly common biomaterial processing technique.

    The patient was a 75 year-old male. Noticing areas of hardening in the lower abdomen, and consequently feelings of systemic fatigue and difficulty in walking, the patient visited a clinic and was diagnosed with kidney failure prior to the visit to our clinic. Computed tomography and magnetic resonance imaging showed thickness of the rectus abdominis muscle and the bladder wall, and bilateral hydronephrosis was also identified. As no explicit tumor was identified in the bladder, the patient underwent biopsies of the abdominal wall and bladder membrane mucous, and was diagnosed with a plasmacytoid urothelial carcinoma primarily developed in the bladder. The patient displayed a poor general state of health and died five months after the diagnosis. It is known that plasmacytoid urothelial carcinomas progress rapidly and the prognosis is poorer than for the micropapillary variant. It is important to obtain a tissue specimen in the early stage of this disease because there are cases in which no explicit tumor can be identified. Furthermore, the value of carbohydrate antigen (CA) 19-9 of the patient was much higher than would be expected as normal at the first visit. It kept rising during the follow-up and was useful as a marker to indicate the progress of the disease.

    Introduction. Abdominal adhesions can cause serious morbidity and complicate subsequent operations. Their diagnosis is often one of exclusion due to a lack of a reliable, non-invasive diagnostic technique. Development and testing of a candidate technique are described below. Method. During respiration, smooth visceral sliding motion occurs between the abdominal contents and the walls of the abdominal cavity. We describe a technique involving image segmentation and registration to calculate shear as an analogue for visceral slide based on the tracking of structures throughout the respiratory cycle. The presence of an adhesion is attributed to a resistance to visceral slide resulting in a discernible reduction in shear. The abdominal movement due to respiration is captured in sagittal dynamic MR images. Results. Clinical images were selected for analysis, including a patient with a surgically confirmed adhesion. Discernible reduction in shear was observed at the location of the adhesion while a consistent, gradually changing shear was observed in the healthy volunteers. Conclusion. The technique and its validation show encouraging results for adhesion detection but a larger study is now required to confirm its potential. PMID:26880884

    A 53-year-old man presented with a continuous high fever and was diagnosed with diffuse large B-cell lymphoma with metastasis to the lung, spleen, and mesenterium. He was treated with cyclophosphamide and prednisolone followed by administration of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy 20 days later. Two days after initiation of CHOP therapy, the patient complained of severe abdominal pain. Perforative peritonitis was diagnosed using abdominal computed tomography. A perforation of the small intestine approximately 160 cm distal to the Treitz ligament was uncovered during emergency laparotomy. The risk of leakage was considered too high for anastomosis of the small intestine to be performed. Further, construction of an intestinal stoma could result in a high-output syndrome that could lead to difficulty in resuming chemotherapy. Based on these considerations, we fixed the anastomotic region to the abdominal wall using a technique similar to construction of an intestinal stoma. Post-operative anastomotic leakage did not occur. Nine days later, a perineal hernia was noted near the anastomotic site and a second operation was performed. The anastomotic site was placed back into the abdominal cavity during this operation. CHOP therapy was resumed 16 days after the first operation.

    From July 1983 through December 1987, 300 consecutive patients with penetrating gunshot wounds of the abdomen causing visceral or vascular injuries were treated. Resuscitative thoracotomy was required in 20 patients (6.6%), and only two survived. The most commonly injured organs were the small bowel (60%), colon (41.6%), liver (29.3%), vascular structures (24.6%), stomach (17.3%), and kidney (17.0%). The overall survival rate for the series was 88.3%; however, if only the 226 patients without vascular injuries are considered, the survival rate was 97.3%. In the 35 patients who died, the blood pressure on admission was 51 mmHg, 18 required a resuscitative thoracotomy, four visceral or vascular injuries were present, and the median blood replacement was 18 units. The cause of death was perioperative shock in 30 patients (85.7%), whereas five patients (14.3%) died of sepsis and multiple organ failure. The most common postoperative complication in survivors and patients who died later in the study was an intra-abdominal abscess (3.0%). Rapid conservative operative techniques for civilian gunshot wounds leads to few postoperative complications and an excellent survival rate, especially if vascular injuries are not present.

    Background: This study was performed to determine the demographic and outcome of penetrating abdominal trauma in patients attending to emergency medicine department. Materials and Methods: This was a descriptive cross-sectional study in Imam Hossein Medical Center. Seventy five patients who came to our department with penetrating abdominal trauma during a 1 year period were enroled into this study and their demographic data and outcome (during the hospitalization) were recorded. The study was at Imam Hossein Medical Center, Tehran, Iran, from 2009 to 2010. Results: Our findings indicate these notable results: 84% of patients were less than 40 years old, most patients attended emergency department during the spring and summer, 72 patients (96%) arrived between 7 pm and 7 am, 74 patients (98.7%) had stab wound and one person (1.3%) was shot, eventually 46 patients (61%) had laparatomy performed and 2 patients (2.7%) died. 59 patients out of 75 study cases appealed to police department and legal medicine council. Conclusions: The incidence of abdominal penetrating trauma due to stab wound is much higher than gunshot in our community, which indicates the importance of educating the emergency staff and preparing the emergency department work place to attend to these patients, especially during the night hours.

    The aim of this study was to conduct a preclinical evaluation of the behaviour of a new type of abdominal LW prosthesis (Ciberlastic), which was designed with a non-absorbable elastic polyurethane monofilament (Assuplus, Assut Europe, Italy) to allow greater adaptability to mechanical area requirements and higher bio-mimicking with the newly formed surrounding tissues. Our hypothesis was that an increase in the elasticity of the mesh filament could improve the benefits of LW prostheses. To verify our hypothesis, we compared the short- and long-term behaviour of Ciberlastic and Optilene(®) elastic commercial meshes by repairing the partially herniated abdomen in New Zealand White rabbits. The implanted meshes were mechanically and histologically assessed at 14 and 180 days post-implant. We mechanically characterized the partially herniated repaired muscle tissue and also determined mesh shrinkage at different post-implant times. This was followed by a histological study in which the tissue incorporation process was analysed over time. The new prosthesis designed by our group achieved good behaviour that was similar to that of Optilene(®), one of the most popular LW prostheses on the market, with the added advantage of its elastic property. The mechanical properties are significantly lower than those of the polypropylene Optilene(®) mesh, and the new elastic mesh meets the basic mechanical requirements for positioning in the abdominal wall, which was also demonstrated by the absence of recurrences after implantation in the experimental model. We found that the growth of a connective tissue rich in collagen over the hernial defect and the proper deposit of the collagen fibres in the regenerated tissue substantially modified the original properties of the mesh, thereby increasing its biomechanical strength and making the whole tissue/mesh stiffer.

    An abdominal aortic aneurysm (AAA) is an area of a localized widening of the abdominal aorta, with a frequent presence of thrombus. A ruptured aneurysm can cause death due to severe internal bleeding. AAA thrombus segmentation and quantitative analysis are of paramount importance for diagnosis, risk assessment, and determination of treatment options. Until now, only a small number of methods for thrombus segmentation and analysis have been presented in the literature, either requiring substantial user interaction or exhibiting insufficient performance. We report a novel method offering minimal user interaction and high accuracy. Our thrombus segmentation method is composed of an initial automated luminal surface segmentation, followed by a cost function-based optimal segmentation of the inner and outer surfaces of the aortic wall. The approach utilizes the power and flexibility of the optimal triangle mesh-based 3-D graph search method, in which cost functions for thrombus inner and outer surfaces are based on gradient magnitudes. Sometimes local failures caused by image ambiguity occur, in which case several control points are used to guide the computer segmentation without the need to trace borders manually. Our method was tested in 9 MDCT image datasets (951 image slices). With the exception of a case in which the thrombus was highly eccentric, visually acceptable aortic lumen and thrombus segmentation results were achieved. No user interaction was used in 3 out of 8 datasets, and 7.80 +/- 2.71 mouse clicks per case / 0.083 +/- 0.035 mouse clicks per image slice were required in the remaining 5 datasets.

    The most common surgical repair of abdominal wall hernia goes through implanting a mesh that substitutes the abdominal muscle/fascia while it is healing. To reduce the risk of relapse or possible complications, this mesh needs to mimic the mechanical behavior of the muscle/fascia, which nowadays is not fully determined. The aim of this work is to develop a methodology to characterize in vivo the passive mechanical behavior of the abdominal wall. For that, New Zealand rabbits were subjected to pneumoperitoneum tests, taking the inner pressure from 0 mmHg to 12 mmHg, values similar to those used in human laparoscopies. Animals treated were divided into two groups: healthy and herniated animals with a surgical mesh (polypropylene Surgipro(TM) Covidien) previously implanted. All experiments were recorded by a stereo rig composed of two synchronized cameras. During the postprocessing of the images, several points over the abdominal surface were tracked and their coordinates extracted for different levels of internal pressure. Starting from that, a three dimensional model of the abdominal wall was reconstructed. Pressure-displacement curves, radii of curvature and strain fields were also analysed. During the experiments, animals tissue mostly deformed during the first levels of pressure, showing the noticeable hyperelastic passive behavior of abdominal muscles. Comparison between healthy and herniated specimen displayed a strong stiffening for herniated animals in the zone where the high density mesh was situated. Cameras were able to discern this change, so this method can be used to measure the possible effect of other meshes.

    Background Abdominal wall defects and hernias are commonly repaired with synthetic or biological materials. Adhesions and recurrences are a common problem. A study was conducted to compare Chitosan coated polypropylene mesh and a polypropylene–polydioxanone composite with oxidized cellulose coating mesh (Proceed™) in repair of abdominal wall defect in a Rabbit hernia model. Methods A randomized controlled experimental study was done on twelve New Zealand white rabbits. A ventral abdominal defect was created in each of the rabbits. The rabbits were divided into two groups. In one group the defect was repaired with Chitosan coated polypropylene mesh and Proceed mesh™ in the other. The rabbits were operated in two phases. They were followed up at four weeks and twelve weeks respectively after which the rabbits were sacrificed. They were evaluated by open exploration and histopathological examination. Their efficacy in reducing adhesion and ability of remodeling and tissue integration were studied. Results There was no statistical significance in the area of adhesion, the force required to remove the adhesions, tissue integration and remodeling between Chitosan and Proceed™ group. Histological analysis revealed that the inflammatory response, fibrosis, material degradation and remodeling were similar in both the groups. There were no hernias, wound infection or dehiscence in any of the studied animals. Conclusion Chitosan coated polypropylene mesh was found to have similar efficacy to Proceed™ mesh. Chitosan coated polypropylene mesh, can act as an anti adhesive barrier when used in the repair of incisional hernias and abdominal wall defects. PMID:26594357

    Background: Posterior abdominal wall deficiency (PAWD) is a tear in the external oblique aponeurosis or the conjoint tendon causing a posterior wall defect at the medial end of the inguinal canal. It is often known as sportsman's hernia and is believed to be caused by repetitive stress. Objective: To assess lower limb and abdominal muscle strength of patients with PAWD before intervention compared with matched controls; to evaluate any changes following surgical repair and rehabilitation. Methods: Sixteen subjects were assessed using a questionnaire, isokinetic testing of the lower limb strength, and pressure biofeedback testing of the abdominals. After surgery and a six week rehabilitation programme, the subjects were re-evaluated. A control group were assessed using the same procedure. Results: Quadriceps and hamstrings strength was not affected by this condition. A deficit hip muscle strength was found on the affected limb before surgery, which was significant for the hip flexors (p = 0.05). Before surgery, 87% of the patients compared with 20% of the controls failed the abdominal obliques test. Both the injured and non-injured sides had improved significantly in strength after surgery and rehabilitation. The strength of the abdominal obliques showed the most significant improvement over the course of the rehabilitation programme. Conclusions: Lower limb muscle strength may have been reduced as the result of disuse atrophy or pain inhibition. Abdominal oblique strength was deficient in the injured patients and this compromises rotational control of the pelvis. More sensitive investigations (such as electromyography) are needed to assess the link between abdominal oblique function and groin injury. PMID:12547744

    Right atrial wall rupture after blunt chest trauma is a catastrophic event associated with high mortality rates. We report the case of a 24-year-old woman who was ejected 40 feet during a motor vehicle accident. Upon presentation, she was awake and alert, with a systolic blood pressure of 100 mmHg. Chest computed tomography disclosed a large pericardial effusion; transthoracic echocardiography confirmed this finding and also found right ventricular diastolic collapse. A diagnosis of cardiac tamponade with probable cardiac injury was made; the patient was taken to the operating room, where median sternotomy revealed a 1-cm laceration of the right atrial appendage. This lesion was directly repaired with 4-0 polypropylene suture. Her postoperative course was uneventful, and she continued to recover from injuries to the musculoskeletal system. This case highlights the need for a high degree of suspicion of cardiac injuries after blunt chest trauma. An algorithm is proposed for rapid recognition, diagnosis, and treatment of these lesions.

    Traumatic brain and spine injury (TBI/TSI) is a leading cause of death and lifelong disability in children. The biomechanical properties of the child's brain, skull, and spine, the size of the child, the age-specific activity pattern, and variance in trauma mechanisms result in a wide range of age-specific traumas and patterns of brain and spine injuries. A detailed knowledge about the various types of primary and secondary pediatric head and spine injuries is essential to better identify and understand pediatric TBI/TSI, which enhances sensitivity and specificity of diagnosis, will guide therapy, and may give important information about the prognosis.

    In the present study a computational finite element technique is proposed to simulate the mechanical response of muscles in the abdominal wall. This technique considers the active behavior of the tissue taking into account both collagen and muscle fiber directions. In an attempt to obtain the computational response as close as possible to real muscles, the parameters needed to adjust the mathematical formulation were determined from in vitro experimental tests. Experiments were conducted on male New Zealand White rabbits (2047±34g) and the active properties of three different muscles: Rectus Abdominis, External Oblique and multi-layered samples formed by three muscles (External Oblique, Internal Oblique, and Transversus Abdominis) were characterized. The parameters obtained for each muscle were incorporated into a finite strain formulation to simulate active behavior of muscles incorporating the anisotropy of the tissue. The results show the potential of the model to predict the anisotropic behavior of the tissue associated to fibers and how this influences on the strain, stress and generated force during an isometric contraction.

    Gross and histopathological features of surgically excised squamous cell carcinomas (SCC) observed in thirteen local Libyan ewes were reported. The age of the ewes enrolled in the current study ranged from 2 to 3 years. The cases were admitted to private veterinary clinics in south-western region of Tripoli, Libya, during the period between July 2014 and October 2015. All lesions were located in the right and left lateral abdominal wall (caudo-ventrally) with a size range of 8 to 11cm in diameter. The tumor masses have been removed by surgical excision. The histopathological examination of surgically excised masses has revealed the characteristic cell nests of SCC showing central keratinization and hyalinization with presence of apoptotic bodies, fattened keratinocytes, and a heavy interstitial infiltration of neutrophils and lymphocytes. The follow up of the cases showed no signs of tumor reoccurrence. In conclusion, SCC in Libyan sheep affects mainly the woolless areas and can be successfully removed by surgical excision.

    Nephropexy remains standard for symptomatic nephroptosis, and several minimally-invasive techniques have been described. Triangulation sutures placed between the abdominal wall and the renal capsule are often difficult to tie tightly due to the confined working space. We propose a technique modification to fixate the kidney utilizing the da Vinci Surgical System robot and Lapra-Ty absorbable suture clips. Four female patients with symptomatic nephroptosis diagnosed via kidney hypermobility demonstrated on intravenous urography (IVU) underwent robotic-assisted laparoscopic nephropexy (RALNP) from February 2008 to April 2010. After complete mobilization and stripping of perirenal fat, several 0 Vicryl sutures were placed in a "figure of eight" fashion and tied loosely. Subsequently we utilized a Lapra-Ty to tighten the stitch serially and fixate the kidney. The mean age was 46 years (43-52); one patient underwent simultaneous pyeloplasty and one underwent partial nephrectomy in the ipsilateral kidney. There were no intraoperative complications and two postoperative complications, both Clavien grade I. All patients were asymptomatic postoperatively at a mean follow-up of 9.2 months (1-28), and had no evidence of kidney hypermobility on upright IVU or diuretic renal scintigraphy (RS) scan at 6 weeks postoperatively. RALNP is a viable option in the treatment of symptomatic nephroptosis. Secure placement of several "pexing" sutures helps to ensure appropriate security of these itinerant kidneys. Our technique modification corrects kidney hypermobility while improving symptoms related to nephroptosis. PMID:27628279

    Background: Standard abdominoplasty rectus plication techniques may not suffice for severe cases of rectus diastasis. In the authors’ experience, prosthetic mesh facilitates the repair of severe rectus diastasis with or without concomitant ventral hernias. Methods: A retrospective review of all abdominal wall surgery patients treated in the past 8 years by the senior author (G.A.D.) was performed. Patients with abdominoplasty and either rectus diastasis repair with mesh or a combined ventral hernia repair were analyzed. Results: Thirty-two patients, 29 women and three men, underwent mesh-reinforced midline repair with horizontal or vertical abdominoplasty. Patient characteristics included the following: mean age, 53 years; mean body mass index, 26 kg/m2; average width of diastasis or hernia, 6.7 cm; and average surgery time, 151 minutes. There were no surgical-site infections and two surgical-site occurrences—two seromas treated with drainage in the office. After an average of 471 days’ follow-up, none of the patients had recurrence of a bulge or a hernia. Conclusions: For patients with significant rectus diastasis, with or without concomitant hernias, the described mesh repair is both safe and durable. Although this operation requires additional dissection and placement of prosthetic mesh in the retrorectus plane, it may be safely combined with standard horizontal or vertical abdominoplasty skin excision techniques to provide an aesthetically pleasing overall result.

    Finite element method based patient-specific wall stress in abdominal aortic aneurysm (AAA) may provide a more accurate rupture risk predictor than the currently used maximum transverse diameter. In this study, we have investigated the sensitivity of the wall stress in AAA with respect to geometrical variations. We have acquired MR and CT images for four patients with AAA. Three individual users have delineated the AAA vessel wall contours on the image slices. These contours were used to generate synthetic feature images for a deformable model based segmentation method. We investigated the reproducibility and the influence of the user variability on the wall stress. For sufficiently smooth models of the AAA wall, the peak wall stress is reproducible for three out of the four AAA geometries. The 0.99 percentiles of the wall stress show excellent reproducibility for all four AAAs. The variations induced by user variability are larger than the errors caused by the segmentation variability. The influence of the user variability appears to be similar for MR and CT. We conclude that the peak wall stress in AAA is sensitive to small geometrical variations. To increase reproducibility it appears to be best not to allow too much geometrical detail in the simulations. This could be achieved either by using a sufficiently smooth geometry representation or by using a more robust statistical parameter derived from the wall stress distribution.

    Desmoid tumors are rare soft tissue tumors considered to have locally infiltrative features without distant metastasis until now. Although they are most commonly intraabdominal, very few cases have extra-abdominal locations. The origin of intrathoracic desmoid tumors is predominantly the chest wall with occasional involvement of pleura. True intrathoracic primary desmoid tumors with no involvement of the chest wall or pleura are extremely rare. We recently experienced a case of true intrathoracic desmoid tumor presenting as multiple lung nodules at 13 years after resection of a previous intraabdominal desmoid tumor.

    Our static finite element analysis (FEA) of both idealized and real clinical models has shown that the maximum diameter and asymmetry have substantial influence on the AAA wall stress distribution. The thrombus inside the AAA was also found to reduce the magnitude of the wall stresses. To achieve a better understanding of the wall stress distribution in real AAAs, a dynamic FEA was also performed. We considered models, both symmetric and non-symmetric, in which the aorta is assumed isotropic with nonlinear material properties. For the limiting case of rigid walls, the evolution of the flow pattern and the wall shear stresses due to fluid flow at different stages of cardiac cycle predicted by our simulations are compared with experimental results obtained in in-vitro models. A good agreement is found between both results. Finally, we have extended the analysis to the physiologically correct case of deformable walls and characterized the transient effects on the wall stresses.

    Objective Porcine acellular dermal matrices (ADM) have been widely used in experimental and clinical research for abdominal wall repair. Compared to porcine small intestinal submucosa (SIS), the effect of these matrices on the regenerative capacity of blood vessels is still not ideal. Multi-walled carbon nanotubes (MWNTs) can more effectively transport VEGF to cells or tissues because of their large specific surface area and interior cavity. In this study, we explored the safety and efficacy of implanted VEGF-loaded MWNT composite scaffolds in vitro and vivo to repair abdominal wall defects. Materials and Methods VEGF-loaded MWNTs were prepared by a modified plasma polymerization treatment. Four composite scaffolds were evaluated for cytotoxicity, proliferation, and release dynamics. We created 3 cm×4 cm abdominal wall defects in 43 Sprague-Dawley rats. After implantation times of 2, 4, 8, and 12 weeks, the scaffolds and the surrounding tissues were collected and examined by gross inspection, biomechanical testing, and histological examination. Results A 5–10 nm poly(lactic-co-glycolic acid) (PLGA) film was evenly distributed on MWNTs. The 3% MWNT composite group showed lower cytotoxicity and appropriate release performance, and it was thus tested in vivo. In rats with the 3% composite implanted, host cells were prevented from migrating to the ADM at 2 weeks, vascularization was established more rapidly at 12 weeks, and the values for both the maximum load and the elastic modulus were significantly lower than in the ADM-alone group (p<0.01). Histological staining revealed that the MWNT was still not completely eliminated 12 weeks after implantation. Conclusion MWNTs were able to carry VEGF to cells or tissues, and the 3% MWNT composite material showed lower cytotoxicity and had an appropriate release performance, which prompted faster vascularization of the ADM than other scaffolds. Nevertheless, the MWNTs induced harmful effects that should be carefully

    2012-01-01

    Introduction Herniation of the liver through an anterior abdominal wall hernia defect is rare. To the best of our knowledge, only three cases have been described in the literature. Case presentation A 70-year-old Mexican woman presented with a one-week history of right upper quadrant abdominal pain, nausea, vomiting, and jaundice to our Department of General Surgery. Her medical history included an open cholecystectomy from 20 years earlier and excessive weight. She presented with jaundice, abdominal distension with a midline surgical scar, right upper quadrant tenderness, and a large midline abdominal wall defect with dullness upon percussion and protrusion of a large, tender, and firm mass. The results of laboratory tests were suggestive of cholestasis. Ultrasound revealed choledocholithiasis. A computed tomography scan showed a protrusion of the left hepatic lobe through the anterior abdominal wall defect and a well-defined, soft tissue density lesion in the right adrenal topography. An endoscopic common bile duct stone extraction was unsuccessful. During surgery, the right adrenal tumor was resected first. The hernia was approached through a median supraumbilical incision; the totality of the left lobe was protruding through the abdominal wall defect, and once the lobe was reduced to its normal position, a common bile duct surgical exploration with multiple stone extraction was performed. Finally, the abdominal wall was reconstructed. Histopathology revealed an adrenal myelolipoma. Six months after the operation, our patient remains in good health. Conclusions The case of liver herniation through an incisional anterior abdominal wall hernia in this report represents, to the best of our knowledge, the fourth such case reported in the literature. The rarity of this medical entity makes it almost impossible to specifically describe predisposing risk factors for liver herniation.

    Background Airway clearance is frequently needed by patients suffering from blunt chest wall trauma. High Frequency Chest Wall Oscillation (HFCWO) has been shown to be effective in helping to clear secretions from the lungs of patients with cystic fibrosis, bronchiectasis, asthma, primary ciliary dyskinesia, emphysema, COPD, and many others. Chest wall trauma patients are at increased risk for development of pulmonary complications related to airway clearance. These patients frequently have chest tubes, drains, catheters, etc. which could become dislodged during HFCWO. This prospective observational study was conducted to determine if HFCWO treatment, as provided by The Vest™ Airway Clearance System (Hill-Rom, Saint Paul, MN), was safe and well tolerated by these patients. Methods Twenty-five blunt thoracic trauma patients were entered into the study. These patients were consented. Each patient was prescribed 2, 15 minute HFCWO treatments per day using The Vest® Airway Clearance System (Hill-Rom, Inc., St Paul, MN). The Vest® system was set to a frequency of 10–12 Hz and a pressure of 2–3 (arbitrary unit). Physiological parameters were measured before, during, and after treatment. Patients were free to refuse or terminate a treatment early for any reason. Results No chest tubes, lines, drains or catheters were dislodged as a result of treatment. One patient with flail chest had a chest tube placed after one treatment due to increasing serous effusion. No treatments were missed and continued without further incident. Post treatment survey showed 76% experienced mild or no pain and more productive cough. Thirty days after discharge there were no deaths or hospital re-admissions. Conclusion This study suggests that HFCWO treatment is safe for trauma patients with lung and chest wall injuries. These findings support further work to demonstrate the airway clearance benefits of HFCWO treatment. PMID:18837992

    Purpose. The aim of this study was to present abdominal wall reconstruction using a porcine vascular graft seeded with MSC (mesenchymal stem cells) on rat model. Material and Methods. Abdominal wall defect was prepared in 21 Wistar rats. Acellular porcine-vascular grafts taken from aorta and prepared with Triton X were used. 14 aortic grafts were implanted in place, of which 7 grafts were seeded with rat MSC cells (Group I), and 7 were acellular grafts (Group II). As a control, 7 standard polypropylene meshes were used for defect augmentation (Group III). The assessment method was performed by HE and CD31 staining after 6 months. The mechanical properties have been investigated by Zwick&Roell Z0.5. Results. The strongest angiogenesis and lowest inflammatory response were observed in Group I. Average capillaries density was 2.75, 0.75, and 1.53 and inflammatory effect was 0.29, 1.39, and 2.72 for Groups I, II, and III, respectively. The means of mechanical properties were 12.74 ± 1.48, 7.27 ± 1.56, and 14.4 ± 3.7 N/cm in Groups I and II and control, respectively. Conclusions. Cell-seeded grafts have better mechanical properties than acellular grafts but worse than polypropylene mesh. Cells improved mechanical and physiological properties of decellularized natural scaffolds. PMID:25705696

    Insufficient early vascularization in biological meshes, resulting in limited host tissue incorporation, is thought to be the primary cause for the failure of abdominal wall defect repair after implantation. The sustained release of exogenous angiogenic factors from a biocompatible nanomaterial might be a way to overcome this limitation. In the study reported here, multiwalled carbon nanotubes (MWNT) were functionalized by plasma polymerization to deliver vascular endothelial growth factor165 (VEGF165). The novel VEGF165-controlled released system was incorporated into porcine small intestinal submucosa (PSIS) to construct a composite scaffold. Scaffolds incorporating varying amounts of VEGF165-loaded functionalized MWNT were characterized in vitro. At 5 weight percent MWNT, the scaffolds exhibited optimal properties and were implanted in rats to repair abdominal wall defects. PSIS scaffolds incorporating VEGF165-loaded MWNT (VEGF-MWNT-PSIS) contributed to early vascularization from 2-12 weeks postimplantation and obtained more effective collagen deposition and exhibited improved tensile strength at 24 weeks postimplantation compared to PSIS or PSIS scaffolds, incorporating MWNT without VEGF165 loading (MWNT-PSIS).

    Abdominal wall muscles have a unique morphology suggesting a complex role in generating and transferring force to the spinal column. Studying passive mechanical properties of these muscles may provide insights into their ability to transfer force among structures. Biopsies from rectus abdominis (RA), external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) were harvested from male Sprague-Dawley rats, and single muscle fibers and fiber bundles (4-8 fibers ensheathed in their connective tissue matrix) were isolated and mechanically stretched in a passive state. Slack sarcomere lengths were measured and elastic moduli were calculated from stress-strain data. Titin molecular mass was also measured from single muscle fibers. No significant differences were found among the four abdominal wall muscles in terms of slack sarcomere length or elastic modulus. Interestingly, across all four muscles, slack sarcomere lengths were quite long in individual muscle fibers (>2.4 µm), and demonstrated a significantly longer slack length in comparison to fiber bundles (p < 0.0001). Also, the extracellular connective tissue matrix provided a stiffening effect and enhanced the resistance to lengthening at long muscle lengths. Titin molecular mass was significantly less in TrA compared to each of the other three muscles (p < 0.0009), but this difference did not correspond to hypothesized differences in stiffness.

    Purpose: The voluntary breath-hold (BH) technique is a simple method to control the respiration-related motion of a tumor during irradiation. However, the abdominal and chest wall position may not be accurately reproduced using the BH technique. The purpose of this study was to examine whether visual feedback can reduce the fluctuation in wall motion during BH using a new respiratory monitoring device. Methods and Materials: We developed a laser-based BH monitoring and visual feedback system. For this study, five healthy volunteers were enrolled. The volunteers, practicing abdominal breathing, performed shallow end-expiration BH (SEBH), shallow end-inspiration BH (SIBH), and deep end-inspiration BH (DIBH) with or without visual feedback. The abdominal and chest wall positions were measured at 80-ms intervals during BHs. Results: The fluctuation in the chest wall position was smaller than that of the abdominal wall position. The reproducibility of the wall position was improved by visual feedback. With a monitoring device, visual feedback reduced the mean deviation of the abdominal wall from 2.1 {+-} 1.3 mm to 1.5 {+-} 0.5 mm, 2.5 {+-} 1.9 mm to 1.1 {+-} 0.4 mm, and 6.6 {+-} 2.4 mm to 2.6 {+-} 1.4 mm in SEBH, SIBH, and DIBH, respectively. Conclusions: Volunteers can perform the BH maneuver in a highly reproducible fashion when informed about the position of the wall, although in the case of DIBH, the deviation in the wall position remained substantial.

    Penetrating abdominal trauma has been traditionally treated by exploratory laparotomy. Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically. PMID:27525150

Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically. PMID:27525150

    A case of complete transection of the common bile duct due to abdominal blunt injury in a 49-year-old man is presented. The rarity of this injury and its initial presentation as a pancreatic pseudocyst warrant its description. This patient was diagnosed as having bile duct injury following ascites aspiration. Common bile duct transection was documented and a choledochostomy was done. However, bile leaked into the peritoneal cavity one week after the operation. A Roux-en-Y choledochojejunostomy was done successfully in a second operation. Delayed diagnosis is common in these kinds of injuries, but it should be considered when a patient has bile ascites, abdominal distention and jaundice after a blunt abdominal injury. A review of the literature, methods of diagnosis and the technique of surgical repair are described.

    Assessing the risk for abdominal aortic aneurysm (AAA) rupture is critical in the management of aneurysm patients and an individual assessment is possible with the biomechanical rupture risk assessment. Such an assessment could potentially be improved by a constitutive AAA wall model that accounts for irreversible damage-related deformations. Because of that the present study estimated the elastic and inelastic properties of the AAA wall through a mixed experimental-numerical approach. Specifically, finite element (FE) models of bone-shaped tensile specimens were used to merge data from failure testing of the AAA wall with their measured collagen orientation distribution. A histo-mechanical constitutive model for collagen fibers was employed, where plastic fibril sliding determined not only remaining deformations but also weakening of the fiber. The developed FE models were able to replicate the experimentally recorded load-displacement property of all 16 AAA wall specimens that were investigated in the study. Tensile testing in longitudinal direction of the AAA defined a Cauchy strength of 569(SD 411) kPa that was reached at a stretch of 1.436(SD 0.118). The stiffness and strength of specimens decreased with the wall thickness and were elevated (p = 0.018; p = 0.030) in patients with chronic obstructive pulmonary disease (COPD). Smoking affected the tissue parameters that were related to the irreversible deformation response, and no correlation with gender and age was found. The observed effects on the biomechanical properties of the AAA wall could have long-term consequences for the management of aneurysm patients, i.e., specifically they might influence future AAA rupture risk assessments. However, in order to design appropriate clinical validation studies our findings should firstly be verified in a larger patient cohort. PMID:23263935

    Symptomatic heterotopic ossification of abdominal surgical incisions is a rare occurrence. We present a 67-year-old man with severe discomfort caused by heterotopic ossification extending from the xiphoid to the umbilicus. The patient underwent an abdominal aortic aneurysm repair 3 years before our treatment. A 13 × 3.5 cm ossified lesion was excised. The resulting midline defect was closed using component separation and inlay Strattice. Tension-free midline adaptation of the recti muscles was achieved. A computed tomography scan of the abdomen 6 months after the surgery showed no recurrence or hernias. Heterotopic ossification in symptomatic patients has previously been treated with excision and primary closure. We believe that tension-free repair is important to prevent recurrence. Acellular dermal matrix may add to this effect and also compartmentalize the process. PMID:27536495

    A canine model was designed to evaluate the changes in abdominal aortic aneurysm (AAA) pressure and wall stress after endovascular repair. Eight canines underwent laparotomy and creation of an AAA. The aneurysm was then excluded with a transluminally placed endovascular graft (TPEG) inserted through the right femoral artery and deployed across the AAA to exclude the infrarenal aortic branches from aortic perfusion. Blood pressure and flow data were recorded for 6 hours. The AAA blood pressure decreased from 135 +/- 9.3 mm Hg before exclusion to 45 +/- 17.6 mm Hg at 10 minutes after exclusion (p < 0.001). At 6 hours, AAA blood pressure had declined further to 26 +/- 12.5 mm Hg. Blood flow in the excluded iliac artery decreased from a baseline of 242 +/- 58 ml/min to 41 +/- 29 ml/min 10 minutes after TPEG placement (p < 0.001). At 6 hours, flow was reduced to 12 +/- 3.5 ml/min (p < 0.05 compared with that at 10 minutes). Aortic wall stress was significantly reduced by TPEG placement but was only slightly lower than baseline aortic wall stress before AAA creation. The lumbar arteries were patent with retrograde flow in all cases and were found to be the major contributors to postexclusion aneurysm pressure. Endovascular AAA exclusion results in an immediate decrease in blood pressure and wall stress within the excluded aneurysm, but the aneurysm remains perfused by retrograde flow through the lumbar arteries, which resulted in near-baseline levels of aneurysm wall stress in this canine model. Embolization of patient lumbar vessels at prosthesis placement may further reduce the risk of late rupture. PMID:8733869

    This review looks at the implementation of magnetic-based approaches in surgical instruments for abdominal surgeries. As abdominal surgical techniques advance toward minimizing surgical trauma, surgical instruments are enhanced to support such an objective through the exploration of magnetic-based systems. With this design approach, surgical devices are given the capabilities to be fully inserted intraabdominally to achieve access to all abdominal quadrants, without the conventional rigid link connection with the external unit. The variety of intraabdominal surgical devices are anchored, guided, and actuated by external units, with power and torque transmitted across the abdominal wall through magnetic linkage. This addresses many constraints encountered by conventional laparoscopic tools, such as loss of triangulation, fulcrum effect, and loss/lack of dexterity for surgical tasks. Design requirements of clinical considerations to aid the successful development of magnetic surgical instruments, are also discussed.

    Patients with Paragonimiasis westermani show a typical ring form or nodular shadow on chest X-ray, cough, sputum, and hemosputum. Recently, case reports of Paragonimiasis westermani, accompanied by pneumothorax and pleural effusion, as for Paragonimiasis miyazakii, have been increasing. Paragonimus westermani often causes an ectopic infection in various organs such as the peritoneal cavity, pleural cavity, pericardium, liver, adrenal gland and brain. Cutaneous paragonimiasis is considered one of the typical forms of ectopic infection in its earlier phase, but a few unexpected cases of cutaneous Paragonimiasis westermani have also been reported. A 68-year old man, who had never eaten fresh-water crab or raw sliced meat of wild boar, noticed subcutaneous induration of the abdominal wall. The induration had been gradually moving upwards and to the right from the infraumbilical region for over 20 days, and then disappeared at the right upper lateral abdominal wall. Eight months later, he developed severe pain in the right lower chest, and a chest X-ray showed right pleural effusion. Laboratory examinations revealed eosinophilia (WBC 3940/mm3, eosinophil 9%), elevated ESR, and an elevated serum total IgE level (5517 IU/ml). Ouchterlony's double diffusion test performed with the patient's serum in agarose showed strong bands toward Paragonimus westermani antigen, compared to Paragonimus miyazakii antigen. Immunoelectrophoresis with the patient's serum showed specific bands toward Paragonimus westermani antigen. This patient was finally diagnosed as having Paragonimiasis westermani infection, and he responded to praziquantel administration. The clinical course of this patient appears to be rare in cases of Paragonimiasis westermani infection. The clinical course of this case resembled some cases of Paragonimiasis miyazakii infection.(ABSTRACT TRUNCATED AT 250 WORDS)

    Ultrasound is an easy to learn and highly efficient diagnostic tool to complete the clinical examination and improve bedside decision-making. In the trauma room, surgeons are often required to make a quick decision as to whether or not a patient needs an emergency intervention or whether further diagnostics are required. For this reason, education of surgeons in performing focused emergency ultrasound is pivotal. The goal of ICAN is to improve and expand the education of surgeons in Switzerland. This article provides a short review of the most frequent surgical pathologies encountered in the emergency room.

    Objectives To develop and test a method for measuring the relationship between the rise in intra-abdominal pressure and sagittal plane movements of the anterior and posterior vaginal walls during Valsalva in a pilot sample of women with and without prolapse. Methods Mid-sagittal MRI images were obtained during Valsalva while changes in intra-abdominal pressure were measured via a bladder catheter in 5 women with cystocele, 5 women with rectocele, and 5 controls. The regional compliance of the anterior and posterior vagina wall support systems were estimated from the ratio of displacement (mm) of equidistant points along the anterior and posterior vaginal walls to intra-abdominal pressure rise (mmHg). Results The compliance of both anterior and posterior vaginal wall support systems varied along different regions of vaginal wall for all three groups, with the highest compliance found near the vaginal apex and the lowest near the introitus. Women with cystocele had more compliant anterior and posterior vaginal wall support systems than women with rectocele. The movement direction differs between cystocele and rectocele. In cystocele, the anterior vaginal wall moves mostly toward the vaginal orifice in the upper vagina, but in a ventral direction in the lower vagina. In rectocele, the direction of the posterior vaginal wall movement is generally toward the vaginal orifice. Conclusions Movement of the vaginal wall and compliance of its support is quantifiable and was found to vary along the length of the vagina. Compliance was greatest in the upper vagina of all groups. Women with cystocele demonstrated the most compliant vaginal wall support. PMID:24474605

    The changes in the evolution of the spatial and temporal distribution of the WSS and gradients of WSS at different stages of the enlargement of AAAs are important to understand the etiology and progression of this vascular disease, since they affect the wall structural integrity, primarily via the changes induced on the shape, functions and metabolism of the endothelial cells. PIV measurements were performed in aneurysm models, while changing systematically their geometric parameters. We show that, even at very early stages of the disease (dilatation > 30%), the flow separates from the wall and the formation of a large vortex ring followed by internal shear layers leads to the generation of WSS that drastically differ from the healthy vessel. Inside the AAA, the mean WSS decreases to zero and the magnitude of the WSS can be as low as 26% of the value in a healthy vessel. Two regions with distinct patterns of WSS were identified. The region of flow detachment, with oscillatory WSS of very low mean, and the region of flow reattachment, located distally, where large, negative WSS and sustained gradients of WSS are produced as a result of the impact of the vortex ring on the wall.

    Hernia repair and pelvic floor reconstruction are usually accompanied with the implantation of a surgical mesh, which frequently results in a foreign body response with associated complications. An ideal surgical mesh that allows force generation of muscle tissues without significant granulation tissue and/or fibrosis is of significant clinical interest. The objective of the present study was to evaluate the in vitro and in vivo responses of a chitosan coating on polypropylene mesh (Ch-PPM) in comparison with commercially available meshes. We found that application of a 0.5% (w/v) Ch-PPM elicited preferential attachment of myoblasts over fibroblast attachment in vitro. Therefore, we test the hypothesis that 0.5% Ch-PPM will encourage skeletal muscle tissue ingrowth and decrease fibrosis formation in vivo. We implanted 0.5% Ch-PPM, collagen-coated polypropylene mesh (Pelvitex™; C.R. Bard), and polypropylene (Avaulta Solo®; C.R. Bard) alone using a rat abdominal defect model. Force generation capacity and inflammatory response of each mesh were evaluated 2, 4, and 12 weeks postimplantation. We found that chitosan coating is associated with the restoration of functional skeletal muscle with histomorphologic characteristics that resemble native muscle and an early macrophage phenotypic response that has previously been shown to lead to more functional outcomes.

    Reestablishing anterior rectus fascial integrity remains a clinical challenge after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. The main concerns include herniation and bulging due to abdominal weakness. Mesh-assisted closure of the fascial defect has improved bulging and herniation rates but infection, extrusion, and encapsulation are serious concerns with mesh use. Biologic tissue matrices may overcome some of these mesh-related complications. The initial experience of using Strattice for fascial closure after TRAM flap procedure is described in this article. Strattice was in-lain and sutured between the anterior and posterior layers of the rectus fascia, at the rectus muscle donor site. The abdominal wall was closed with progressive tension sutures. Postoperative complications at the donor site were assessed. A total of 16 unilateral and 9 bilateral reconstructions were performed in 25 patients. Length of hospital stay was 2 to 3 days which is shorter than with mesh repair (typically 4-5 days). During a mean follow-up period of 14.0 months, complications occurred in 7 patients (28%): seroma formation (2), minor skin separation (2), superficial skin infection (2), and superficial wound dehiscence (1). Complications were not directly related to Strattice and all, except one (superficial skin infection), were resolved without surgical intervention. In all patients, routine abdominal functions were restored 4 months postoperatively. Strattice is a safe, alternative option to synthetic mesh for fascial repair following TRAM flap breast reconstruction. When used in conjunction with progressive tension suture closure of the abdominal wall, dynamic reconstruction of the abdominal wall with resumption of abdominal function is possible with Strattice.

    The repair of incisional hernias has taken advantage of the strength provided by prosthetic mesh grafts, but the best position for inserting the materials has not been conclusively established. Environmental scanning electron microscopy (ESEM) provides imaging of biologic samples with minimal manipulation. We used ESEM for early imaging of the integration response to polypropylene meshes placed in two anatomic positions in the abdominal wall and correlated results with tensiometric studies. Two macroporous polypropylene prostheses were implanted in a rat model--one on the abdominal aponeurotic layer and one on the peritoneal surface--without creating a wall defect. Studies were performed over implantation intervals of 7, 15, and 30 days in strips obtained from the polypropylene fiber-receptor repair tissue interface. Microscopic appearance, tensile strength, percent elongation, and stiffness were evaluated. Meshes implanted on the abdominal aponeurotic layer showed better early tissue incorporation (higher collagen deposition, capillary density, cell accumulation) and increased tensile strength, reflecting tighter anchorage to the abdominal wall. The percent elongation increased from day 7 to day 30 after implantation, mainly in the deep stratum. The ESEM images correlated well with biomechanical results, indicating the potential of this technique as a powerful, effective tool for use in wound-healing studies.

    Tissue reactions to titanium-nickelide and polypropylen and caprone implants used in surgical treatment of anterior aldomen wall hernias were studied in experiment. Digital density of leukocytes, fibroblasts, vessels, thickness of the capsule were studied. Pronounced inflammatory reaction was observed on day 3 which attenuated on day 14 in case of titanium nickelide and on day 30-60 in case of polypropylene and caprone. Fibroplastic processes start in the first group after 7 days while in the second group only after 30 days of the experiment. Thickness of the capsule around titanium-nickelide was 2-3 times less than around polypropylene and caprone. Thus, titanium-nickelide material is biologically more inert than caprone and polypropylen which are widely used in surgery of hernias. PMID:15154379

    Open abdomen (OA) has been an effective treatment for abdominal catastrophes in traumatic and general surgery. However, management of patients with OA remains a formidable task for surgeons. The central goal of OA is closure of fascial defect as early as is clinically feasible without precipitating abdominal compartment syndrome. Historically, techniques such as packing, mesh, and vacuum-assisted closure have been developed to assist temporary abdominal closure, and techniques such as components separation, mesh-mediated traction, bridging fascial defect with permanent synthetic mesh, or biologic mesh have also been attempted to achieve early primary fascial closure, either alone or in combined use. The objective of this review is to present the challenges of these techniques for OA with a goal of early primary fascial closure, when the patient's physiological condition allows. PMID:26819597

    Background and aims The clinical results of the vertical “vest-over-pants” Mayo repair were evaluated, and the risk factors for incisional hernia recurrence were studied. The purpose of this study is to point out the importance of reducing pre and post operative risk factors in the incisional hernia repair process in order to achieve a physiologically normal abdominal wall. Methods Twenty patients diagnosed with incisional hernia underwent an abdominal reconstruction procedure using the Mayo (Paletot) technique at Bichat Claude Bernard Hospital between 2005 and 2015. All procedures were performed by a single surgeon and all patients were pre-operatively prepared, identifying all coexisting conditions and treating them accordingly before undergoing surgery. Results All patients underwent at least one surgical operation before the hernia repair procedure and a quarter had experienced at least three, prior to this one. Nine patients had a body mass index of >30 kg/m2. Additional risk factors and comorbidities included obesity in 45%, diabetes mellitus in 10%, smoking in 55%, and high blood pressure in 40%. Hernia defect width was from 3 cm (25% F) to 15 cm (5% M) of which nine patients (45%) had a 10 cm defect. Most of the patients had an average hospitalization of 7 days. The patients were carefully monitored and were called on periodic consultations after 3, 6, and 12 months from the moment of the procedure. Patient feedback regarding hernia recurrence and complaints about the scar were noted. Physical examination is essential in determining the hernia recurrence therefore the scar was examined for any abnormalities that may have occurred, which was defined as any palpable or detected fascial defect located within seven centimeters of the hernia repair. Post-operative complications: seroma formation, wound hematoma, superficial and deep wound infection, recurrences and chronic pain were followed and no complications were registered during the follow-up period

    Background Chronic abdominal pain (CAP) is a serious medical condition which needs to be approached with great attention. Chronic abdominal pain may be caused by entrapment of cutaneous branches of intercostal nerves (ACNES). Objectives The aim of this study is the surgery for abdominal wall pain which caused by cutaneous nerve entrapment in children during last 5 years. Materials and Methods In all children with ACNES, we tried conservative treatment with anesthetic and steroid injections. In children who were refractory to conservative treatment, we received surgical procedure like sectioning the entrapped nerve to obtain relief. Results In 12 pediatric patients with chronic abdominal pain, we diagnosed ACNES. Each presented with abdominal pain and a positive Carnett sign. Local nerve blocks using anesthetic and steroid injections are the treatment. In all patients, we tried with local nerve block. In 3 patients, pain improvement occurs in the few minutes, and they were without pain after 5 days. In other 4 patients required a reinjection for pain recurrence. In one patients pain was gone. The maximum reinjection was 3. In other 5 patients, we did operative treatment like sectioning the entrapped nerve. Conclusions Some children with CAP have ACNES. In all children with ACNES, we recommended local nerve blocks. If the local block in 3 times is not helping, neurectomy of the peripheral nerve is method of choice. PMID:23682329

    TGF-β signaling plays critical roles in the pathogenesis of aneurysms; however, it is still unclear whether its role is protective or destructive. In this study, we investigate the role of SMAD3 in the pathogenesis of calcium chloride (CaCl2)-induced abdominal aortic aneurysms (AAA) in Smad3−/−, Smad3+/− and Smad3+/+ mice. We find that loss of SMAD3 drastically increases wall thickening of the abdominal aorta. Histological analyses show significant vessel wall remodeling with elastic fiber fragmentation. Remarkably, under polarized light, collagen fibers in the hyperplastic adventitia of Smad3−/− mice show extensive reorganization accompanied by loosely packed thin and radial collagen fibers. The expressions of matrix metalloproteinases including MMP2, MMP9, and MMP12 and infiltration of macrophage/T cells are drastically enhanced in the vascular wall of Smad3−/− mice. We also observe marked increase of NF-κB and ERK1/2 signaling as well as the expression of nuclear Smad2, Smad4 and TGF-β1 in the vessel wall of Smad3−/− mice. In addition, we find that SMAD3 expression is reduced in the dedifferentiated medial smooth muscle-like cells of human AAA patients. These findings provide direct in vivo evidence to support the essential roles of SMAD3 in protecting vessel wall integrity and suppressing inflammation in the pathogenesis of AAAs. PMID:25985281

    Hernias are defects in which an anatomical fascia is breached resulting in ectopic positioning of an organ into an orifice which routinely does not contain it. Intervention often involves repositioning translocated organs and repair of damaged fascia using exogenous grafts. Despite hernia prevalence, repairs can still fail due to postoperative complications, such as chronic pain and decreased mobility. This study compared repair capacities and characterized the foreign body response elicited by a number of hernia repair grafts to deduce their bulk inflammatory properties while also concluding the point in their fabrication when these are inferred. Materials derived from human dermis (Alloderm(®) ), porcine dermis (Permacol™, patch A, patch D and Strattice(®) ), porcine small-intestinal submucosa (Surgisis™) and a synthetic (multifilament Surgipro™) were implanted into a rat full-thickness abdominal wall excision model, incubated for up to 2 years and characterized histopathologically. Surgisis™ resorbed the fastest of the materials tested (1-3 months) resulting in a mechanically stable parietal peritoneum. Decellularization using sodium dodecyl sulfate (patch A) stimulated a large early inflammatory response which ultimately may have contributed to increased resorption of porcine dermal matrix however the remaining materials typically persisted throughout the 2-year incubation. Cross-linking porcine dermis using 1,6-hexamethylene disocyanate (vs. an identical noncross-linked counterpart) showed no difference in cell recruitment or material integration over 2 years. Typically Strattice(®) and Alloderm(®) recruited larger early populations of cells than Permacol™; however, over extended periods of time in vivo this response normalized. PMID:24155173

    Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations. Pneumothorax can also be quickly detected with ultrasound. During the secondary survey and in patients sustaining low-speed or localized trauma, ultrasound can be used to help detect abdominal organ injuries. This is particularly helpful in patients in whom hemoperitoneum is not identified on an initial scan because findings of organ injuries will expedite the next test, often computed tomography (CT). Moreover, ultrasound can assist in detection of fractures easily obscured on radiography, such as rib and sternal fractures.

    Necrotizing fasciitis (NF) is an uncommon soft tissue infection, usually caused by toxin-producing virulent bacteria. It is characterized by widespread fascial necrosis primarily caused by Streptococcus hemolyticus. Shortly after the onset of the disease, patients become colonized with their own aerobic and anaerobic microflora from the gastrointestinal and/or urogenital tracts. Early diagnosis with aggressive multidisciplinary treatment is mandatory. We describe three clinical cases with NF. The first is a 69 years old man with diabetes mellitus type II, who presented with NF on the posterior chest wall, shoulder and arm. He was admitted to the intensive care unit (ICU) with a clinical picture of severe sepsis. Outpatient treatment and early surgical debridement of the affected zones (inside 3 hours after admittance) and critical care therapy were performed. The second case is of a 63 years old paraplegic man with diabetes mellitus type I. Pressure sores and perineal abscesses progressed to Fournier's gangrene of the perineum and scrotum. He had NF of the anterior abdominal wall and the right thigh. Outpatient treatment and early surgical debridement of the affected zones (inside 6 hour after admittance) and critical care therapy were performed. The third patient was a 56 year old man who had NF of the anterior abdominal wall, flank and retroperitoneal space. He had an operation of the direct inguinal hernia, which was complicated with a bowel perforation and secondary peritonitis. After establishing the diagnosis of NF of the abdominal wall and retroperitoneal space (RS), he was transferred to the ICU. There he first received intensive care therapy, after which emergency surgical debridement of the abdominal wall, left colectomy, and extensive debridement of the RS were done (72 hours after operation of inquinal hernia). On average, 4 serial debridements were performed in each patient. The median of serial debridement in all three cases was four times. Other

    The aim of this study was to determine the effectiveness of mechanical abdominal massage on postoperative pain and ileus after colectomy. We hypothesized that parietal abdominal stimulation could counteract induced pain and postoperative ileus, through common spinal-sensitive pathways, with nociceptive visceral messages. After preoperative randomization, 25 patients (age 52 +/- 5 years) underwent active mechanical massage by intermittent negative pressure on the abdominal wall resulting in aspiration (Cellu M50 device, LPG, Valence, France), and 25 patients (age 60 +/- 6 years) did not receive active mechanical massage (placebo group). Massage sessions began the first day after colectomy and were performed daily until the seventh postoperative day. In the active-massage group, amplitude and frequency were used, which have been shown to be effective in reducing muscular pain, whereas in the placebo group, ineffective parameters were used. Visual analogue scale (VAS) pain scores, doses of analgesics (propacetamol), and delay between surgery and the time to first passage of flatus were assessed. Types and dosages of the anesthetic drugs and the duration of the surgical procedure did not differ between groups. From the second and third postoperative days, respectively, VAS pain scores (P < 0.001) and doses of analgesics (P < 0.05) were significantly lower in patients receiving active massage compared to the placebo group. Time to first passage of flatus was also significantly shorter in the active-massage group (1.8 +/- 0.3 days vs. 3.6 +/- 0.4 days, P < 0.01). No adverse effects were observed. These results suggest that mechanical massage of the abdominal wall may decrease postoperative pain and ileus after colectomy. PMID:11986017

    Multiple injuries resulting from the use of nail guns have been described in the literature; however, to date there has been no report of a nail gun injury to the abdomen. We describe the case of a 30-year-old male tradesperson who suffered a penetrating nail gun injury to the epigastrium, resulting in multiple injuries to the bowel and an inferior vena caval injury with massive haemorrhage. This case demonstrates the wide range of injuries capable of being inflicted by a single penetrating injury, and emphasizes the need for proper training and safety measures in the use of nail guns.

    The segmental omental infarction is a rare self-limited disorder presenting with aspecific clinical symptoms that may mimic several acute abdominal conditions. Therefore, a correct noninvasive diagnosis is important because treatment approaches range from monitoring to surgery. As omental infarction results in an important fat stranding that is much greater than the degree of bowel wall thickening, it suggests a narrower differential diagnosis: appendicitis, diverticulitis, epiploic appendagitis, and mesenteric panniculitis. In this pictorial essay, we point out the importance of imaging in identifying this typical sign allowing alternate diagnoses such as segmental omental infarction that can be conservatively managed.

    The objective of this study was to investigate the effects of Abdominal Hollowing (AH) maneuver on External Oblique (EO), Internal Oblique (IO) and Transversus Abdominis (TrA) muscles in both healthy men and women during the two postures of supine and upright standing. The study was conducted on 43 asymptomatic volunteers (22 males and 21 females) aged 19-44 (27.8±6.4) years. Rehabilitative Ultrasonic Imaging (RUSI) was simultaneously performed to measure muscle thickness in both rest and during AH maneuvers while activation of the TrA during AH was controlled by Pressure Biofeedback (PBF) device. Mixed-model ANOVA with repeated measures design, and Pearson correlation tests were used to analyze the data. Muscle thickness of all muscles was significantly higher for male subjects (F>6.2, p<0.017). The interaction effect of gender and muscle status was significant only for IO (F=7.458, p=0.009) indicating that AH maneuver increased the thickness of IO in men. Interaction effect of posture and muscle status on muscular thickness indicated that changing position only affects the resting thickness of TrA (F=5.617, p=0.023). Standing posture significantly affected the TrA contraction ratio (t=3.122, p=0.003) and TrA preferential activation ratio (t=2.76, p=0.008). There was no relationship between age and muscle thickness (r=0.262, p=0.09). The PBF has been introduced as a clinical and available device for monitoring TrA activity, while RUSI showed that both TrA and IO muscles had activated after AH maneuver. We recommend performing further investigations using electromyography and RUSI simultaneously at more functional postures such as upright standing.

    Highly cellularised 3D-tissue constructs designed to repair large, complex abdominal wall defects were prepared using poly (lactic acid) (PLLA)-collagen scaffolds in vitro using a flow perfusion bioreactor. The PLLA-collagen scaffolds had a unique structure consisting of a collagen sponge formed within the pores of a mechanically stable knitted mesh of PLLA. The effect of the flow perfusion bioreactor culturing conditions was investigated in vitro for 0, 7, 14 and 28 days on scaffolds seeded with dermal fibroblasts. The cultured constructs were subsequently studied subcutaneously (SC) in an in vivo animal model. The results of in vitro studies demonstrated that the perfusion system facilitated increased cell proliferation and homogenous distribution in the PLLA-collagen scaffolds compared to static conditions. A highly cellularised 3D-tissue construct was formed by 7 days incubation under perfusion conditions, with increased cellularity by the 28 day time point. The in vivo model demonstrated that implanting constructs with high cellularity resulted in exceptional cell stabilisation, with the survival of implanted cells and expression of the phenotypically-relevant extracellular matrix proteins collagen types I and III, studied by fluorescence in situ hybridisation (FISH) and immunohistochemistry. The implantation of this porous PPLA-collagen scaffold seeded with dermal fibroblasts following in vitro maturation using a flow perfusion bioreactor system suggests a significant advance over current state-of-the-art procedures for the reconstruction of large, complex abdominal wall tissue defects.

    The use of synthetic surgical mesh materials has been shown to decrease the incidence of hernia recurrence, but can be associated with undesirable effects such as infection, chronic discomfort, and adhesion to viscera. Surgical meshes composed of extracellular matrix (i.e., biologically-derived mesh) are an alternative to synthetic meshes and can reduce some of these undesirable effects but are less frequently used due to greater cost and perceived inadequate strength as the mesh material degrades and is replaced by host tissue. The present study assessed the temporal association between mechanical properties and degradation of biologic mesh composed of urinary bladder matrix (UBM) in a rodent model of full thickness abdominal wall defect. Mesh degradation was evaluated for non-chemically crosslinked scaffolds with the use of (14)C-radiolabeled UBM. UBM biologic mesh was 50% degraded by 26 days and was completely degraded by 90 days. The mechanical properties of the UBM biologic mesh showed a rapid initial decrease in strength and modulus that was not proportionately associated with its degradation as measured by (14)C. The loss of strength and modulus was followed by a gradual increase in these values that was associated with the deposition of new, host derived connective tissue. The strength and modulus values were comparable to or greater than those of the native abdominal wall at all time points. PMID:27619242

    The aim was to determine the volume and degree of asymmetry of quadratus lumborum (QL), obliques, and transversus abdominis; the last two considered conjointly (OT), in tennis and soccer players. The volume of QL and OT was determined using magnetic resonance imaging in professional tennis and soccer players, and in non-active controls (n = 8, 14, and 6, respectively). In tennis players the hypertrophy of OT was limited to proximal segments (cephalic segments), while in soccer players it was similar along longitudinal axis. In tennis players the hypertrophy was asymmetric (18% greater volume in the non-dominant than in the dominant OT, p = 0.001), while in soccer players and controls both sides had similar volumes (p > 0.05). In controls, the non-dominant QL was 15% greater than that of the dominant (p = 0.049). Tennis and soccer players had similar volumes in both sides of QL. Tennis alters the dominant-to-non-dominant balance in the muscle volume of the lateral abdominal wall. In tennis the hypertrophy is limited to proximal segments and is greater in the non-dominant side. Soccer, however, is associated to a symmetric hypertrophy of the lateral abdominal wall. Tennis and soccer elicit an asymmetric hypertrophy of QL.

    Veterinary pathologists commonly encounter lesions of blunt trauma. The development of lesions is affected by the object's mass, velocity, size, shape, and angle of impact and by the plasticity and mobility of the impacted organ. Scrape, impact, and pattern abrasions cause localized epidermal loss and sometimes broken hairs and implanted foreign material. Contusions are best identified after reflecting the skin, and must be differentiated from coagulopathies and livor mortis. Lacerations-traumatic tissue tears-may have irregular margins, bridging by more resilient tissue, deviation of the wound tail, crushed hairs, and unilateral abrasion. Hanging or choking can cause circumferential cervical abrasions, contusions and rupture of hairs, hyoid bone fractures, and congestion of the head. Other special forms of blunt trauma include fractured nails, pressure sores, and dog bites. Ocular blunt trauma causes extraocular and intraocular hemorrhages, proptosis, or retinal detachment. The thoracic viscera are relatively protected from blunt trauma but may develop hemorrhages in intercostal muscles, rib fractures, pulmonary or cardiac contusions or lacerations with subsequent hemothorax, pneumothorax, or cardiac arrhythmia. The abdominal wall is resilient and moveable, yet the liver and spleen are susceptible to traumatic laceration or rupture. Whereas extravasation of blood can occur after death, evidence of vital injury includes leukocyte infiltration, erythrophagocytosis, hemosiderin, reparative lesions of fibroblast proliferation, myocyte regeneration in muscle, and callus formation in bone. Understanding these processes aids in the diagnosis of blunt force trauma including estimation of the age of resulting injuries. PMID:27381403

    Abdominal compartment syndrome (ACS) is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not. PMID:22606517

    Objective: Non-operative management of abdominal injuries has recently become more common. Especially non-operative treatment of blunt abdominal trauma is gaining wide acceptance. In this study, the efficacy of non-operative treatment in abdominal trauma (blunt penetrating) is discussed. Material and Methods: All patients who received treatment due to abdominal trauma from November 2008 to January 2013 were retrospectively analyzed. The demographic characteristics, type of injury, injured organ, type of treatment (operative vs. nonoperative) and mortality data were evaluated. Results: The study includes 115 patients treated for abdominal trauma in our department. The mechanism of trauma was stab wounds in 60%, blunt abdominal trauma in 23.5% and gunshot wounds in 16.5%. Forty-two patients (36.5%) were operated for hemodynamic instability and/or peritonitis on admission. The remaining 63.5% of patients (n=73) were treated nonoperatively, 10 of whom required laparotomy during follow-up. The remaining 63 patients were treated with non-operative management. The success rate for non-operative treatment was 86.3% and there was no difference in terms of the types of injuries. The mortality rate was 4.3% (n= 5) in the whole series, but there were no deaths among the patients who had received non-operative treatment. In the whole patient group 54.2% (n=63) were treated nonoperatively. Conclusion: Nonoperative treatment in abdominal trauma is safe and effective. Patients with clinical stability and normal physical examination findings can be treated nonoperatively with close monitoring. PMID:25931868

    Einleitung: Das optimale Behandlungskonzept eines temporären Bauchdeckenverschlusses (temporary abdominal closure, TAC) bei kritisch kranken viszeralchirurgischen Patienten mit offenem Abdomen („open abdomen“, OA) ist weiterhin unklar. Durch eine VACM-Therapie (vacuum-assisted closure and mesh-mediated fascial traction) scheinen sich gegenüber anderen Verfahren des TAC höhere Faszienverschlussraten (delayed primary fascial closure rate, FCR) realisieren zu lassen. Material und Methoden: Patienten unserer Klinik (n=58), welche in den Jahren 2005 bis 2008 mittels eines VAC/VACM-Behandlungsmanuals behandelt wurden, wurden retrospektiv analysiert. Ergebnisse: Die FCR aller Patienten betrug insgesamt 48,3% (95%-Konfidenzintervall: 34,95–61,78). Bei Patienten, bei denen im Verlauf ein Vicryl-Netz auf Faszienebene implantiert wurde (VACM-Therapie), konnte eine FCR von 61,3% realisiert werden. Die Letalität der mittels VACM therapierten Patienten betrug 45,2% (95%-KI: 27,32–63,97).Schlussfolgerung: Die Ergebnisse der eigenen Untersuchung bestätigen bisherige Studienergebnisse, die eine akzeptable FCR bei non-trauma-Patienten durch Anwendung der VACM-Therapie zeigen konnten. Die VACM-Therapie scheint aktuell Therapiekonzept der ersten Wahl bei Patienten mit OA und Indikation zum TAC zu sein.

    Introduction: The optimal treatment concept for temporary abdominal closure (TAC) in critically ill visceral surgery patients with open abdomen (OA) continues to be unclear. The VACM (vacuum-assisted closure and mesh-mediated fascial traction) therapy seems to permit higher delayed primary fascial closure rates (FCR) than other TAC procedures. Material and methods: Patients of our clinic (n=58) who were treated by application of a VAC/VACM treatment manual in the period from 2005 to 2008 were retrospectively analysed. Results: The overall FCR of all patients was 48.3% (95% confidence interval: 34.95–61.78). An FCR of 61.3% was achieved in patients who had a vicryl mesh implanted at the fascial level (VACM therapy) in the course of treatment. Mortality among patients treated with VACM therapy was 45.2% (95% CI: 27.32–63.97). Conclusions: The results of our own study confirm the results of previous studies which showed an acceptable FCR among non-trauma patients who were treated with VACM therapy. VACM therapy currently appears to be the treatment regime of choice for patients with OA requiring TAC. PMID:27547691

    French physicians dealing with abdominal emergencies are not very familiar with the abdominal compartment syndrome (ACS). Increased abdominal pressure has deleterious consequences on local (intestine, liver, kidney) circulation, leading to death in the absence of correct treatment. Abdominal trauma and ruptured aortic aneurism are the main causes of ACS. Clinical presentation may be misleading: respiratory failure, oliguria or circulatory symptoms are often predominant. Abdominal palpation is inefficient for evaluating intra-abdominal pressure (IAP); only measurement of cystic pressure allows precise evaluation of IAP. Abdominal decompression is the treatment of choice. It must be performed as soon as IAP exceeds 25 mmHg. The procedure may be risky with a high incidence of severe complications when ischaemic territories are reperfused. Recent data underline the importance of compensation of hypovolemia before decompression. Abdominal closure may necessitate various techniques (aponevrotomy, Bogota bags, etc.). At any rate, IAP must remain low at the end of the procedure. In case of suspicion of ACS, early measurement of IAP is mandatory. If pressure is over 25 mmHg, a decompressive procedure must be initiated. PMID:11340703

    Background Damage Control (DC) has improved survival from severe abdominal and extremities injuries. The data on the surgical strategies and outcomes in patients managed with DC for severe thoracic injuries is scarce. Methods Retrospective review of the patients treated with DC for thoracic/pulmonary complex trauma at two level I trauma centers from 2006 to 2010. Subjects 14 and older, were included. Demographics, trauma characteristics, surgical techniques, and resuscitation strategies were reviewed. Results A total of 840 trauma thoracotomies were performed. Damage control thoracotomy (DCT) was done in 31 (3.7%). Pulmonary trauma was found in 25 of them. The median age was 28 (IQR 20–34) years, Revised Trauma Score was 7.11, (IQR 5.44–7.55), and Injury Severity Score was 26 (IQR 25–41). Nineteen patients had gunshot-wounds, four stab-wounds and two blunt trauma. Pulmonary trauma was managed by pneumorrhaphy in three cases, tractotomy in 12, wedge resection in one and packing as primary treatment in 8. Clamping of the pulmonary hilum was used as a last resource in 7 cases. Five patients returned to the ICU with the pulmonary hilum occluded by a vascular clamp or an en masse ligature. These patients underwent a deferred resection within 16 to 90 hours after the initial DCT. Four of them survived. Bleeding from other intra-thoracic sources was found in 20 cases: major vessels in nine, heart in three, and thoracic wall in nine. DCT mortality in pulmonary trauma was 6/25, (24%) due to coagulopathy or persistent bleeding in five cases and to multiorgan failure in one. Conclusion This series describes our experience with DCT in severe lung trauma. We describe pulmonary hilum clamping and deferred lung resection as a viable surgical alternative for major pulmonary injuries, and the use of packing as a definitive method for hemorrhage control.

    Background Components separation technique emerged several years ago as a novel procedure to improve durability of repair for ventral abdominal hernias. Almost twenty-five years since its initial description, little comprehensive risk adjusted data exists on the morbidity of this procedure. This study is the largest analysis to date of short-term outcomes for these cases. Methods The ACS-NSQIP database identified open ventral or incisional hernia repairs with components separation from 2005 to 2012. A data set of cohorts without this technique, matched for preoperative risk factors and operative characteristics, was developed for comparison. A comprehensive risk-adjusted analysis of outcomes and morbidity was performed. Results A total of 68,439 patients underwent open ventral hernia repair during the study period (2245 with components separation performed (3.3%) and 66,194 without). In comparison with risk-adjusted controls, use of components separation increased operative duration (additional 83 min), length of stay (6.4 days vs. 3.8 days, p < 0.001), return to the OR rate (5.9% vs. 3.6%, p < 0.001), and 30-day morbidity (10.1% vs. 7.6%, p < 0.001) with no increase in mortality (0.0% in each group). Conclusions Components separation technique for large incisional hernias significantly increases length of stay and postoperative morbidity. Novel strategies to improve short-term outcomes are needed with continued use of this technique. PMID:27158489

    The soft tissue response to clinically retrieved and decontaminated cover screws was evaluated in a rat model. The cover screws were cleaned by using citric acid, sterile water, hydrogen peroxide and CO2 laser alone or with a combination of these. In addition, decontaminated but not cleaned and unused cover screws were used as negative and positive controls, respectively. After cleaning the cover screws were implanted in the abdominal wall of the rat for 6 weeks. The thickness of the fibrous capsule and the number of macrophages within the capsule were measured by means of light microscopical morphometry. As compared to the negative control, CO2 laser on dry surface, CO2 laser + hydrogen peroxide and the positive control had statistically significant thinner fibrous capsules. As compared to the positive, only laser alone resulted in a similar tissue response. It is concluded that CO2 laser used alone or in combination with hydrogen peroxide may be used clinically for sufficient decontamination of titanium surfaces.

    Incisional hernia is one of the classic complications after abdominal surgery. The chronic, gradual increase in size of some of these hernias is such that the hernia ring widens to a point where there is a loss of substance in the abdominal wall, herniated organs can become incarcerated or strangulated while poor abdominal motility can alter respiratory function. The surgical treatment of small (<5 cm) incisional hernias is safe and straightforward, by either laparotomy or laparoscopy. For large hernias, surgical repair is often difficult. After reintegration of herniated viscera into the abdominal cavity, the abdominal wall defect must be closed anatomically in order to restore the function to the abdominal wall. Prosthetic reinforcement of the abdominal wall is mandatory for long-term successful repair. There are multiple techniques for prosthetic hernia repair, but placement of Dacron mesh in the retromuscular plane is our preference. PMID:23137643

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    Appropriate access to the abdominal cavity is the first and crucial step for successful abdominal surgical intervention. In planning the incision, several variables have to be considered, such as anatomy of the abdominal wall, localization of the target organ, and individual conditions (previous incisions, minimal access surgery, etc). Medial laparotomy is the preferred incision for emergency cases and ill-defined pathologies, allowing access and hence exploration to all quadrants. Transverse laparotomies give superior access to the dorsal and right aspects of the liver and cause less pain in patients unfit for regional anesthetic procedures. Draining of the abdominal cavity is used after various resective and reconstructive procedures, but there is little evidence for its use in a number of operations such as gastric, hepatic, and colorectal resections. Advantages and disadvantages of different abdominal wall incisions and drainages are discussed.

    Lung fluke, Paragonimus westermani of Paragonimus species usually are accompanied by a persistent cough, hemoptysis, and chest pain. Extrapulmonary paragonimiasis caused by ectopic parasites in aberrant locations such as the abdominal wall, abdominal organs, and brain has been reported and the most commonly involved extrapulmonary organ is the brain. We present a case of 56-year-old male patient with intra-abdominal paragonimiasis who underwent laparoscopic excision of abdominal granuloma caused by parasite infection. An intra-abdominal mass associated with eosinophilia might be related to parasite infection. A laparoscopic approach is the most appropriate treatment modality in such benign abdominal pathology.

    Understanding basic ear anatomy and function allows an examiner to quickly and accurately identify at-risk structures in patients with head and ear trauma. External ear trauma (ie, hematoma or laceration) should be promptly treated with appropriate injury-specific techniques. Tympanic membrane injuries have multiple mechanisms and can often be conservatively treated. Temporal bone fractures are a common cause of ear trauma and can be life threatening. Facial nerve injuries and hearing loss can occur in ear trauma.

As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

    Polypropylene mesh is commonly used in the treatment of abdominal hernia. Different approaches were addressed to improve their tissue integration and consequently reduce long-term complications. This study aimed to investigate the effect of alpha-lipoic acid (ALA) co-administration on structural and immunohistochemical (IHC) changes in the subcutaneous tissues of the anterior abdominal wall of the adult rat in response to polypropylene mesh implantation. Forty adult male albino rats were divided into: group I (control), group II (receiving ALA), group III (polypropylene mesh implantation) and group IV (mesh implantation + ALA co-administration). After 4 weeks, subcutaneous tissue samples were prepared for light microscopy and IHC study of CD34 as a marker for angiogenesis. In groups I and II rats, positive CD34 expression was demonstrated by IHC reaction, localized to endothelial cells lining small blood vessels. Group III showed an excess inflammatory reaction, deposition of both regular and irregularly arranged collagen fibres around mesh pores and few elastic fibres. CD34-positive was detected not only in cells lining small blood vessels but also in other cells scattered in the connective tissue indicating angiogenesis. In group IV, ALA co-administration resulted in less inflammatory reaction, regular collagen deposition, enhanced elastic fibres synthesis and a significant increase in CD34-positive cells and small blood vessels reflecting improved angiogenesis. ALA co-administration with polypropylene mesh implantation controlled the inflammatory reaction, helped regular collagen deposition, enhanced elastic fibres synthesis and improved angiogenesis in the subcutaneous tissue of anterior abdominal wall of adult albino rats, suggesting a possible role of ALA in optimizing mesh integration in subcutaneous tissue.

    External abdominal hernia occurs when abdominal organs or tissues leave their normal anatomic site and protrude outside the skin through the congenital or acquired weakness, defects or holes on the abdominal wall, including inguinal hernia, umbilical hernia, femoral hernia and so on. Acute incarcerated hernia is a common surgical emergency. With advances in minimally invasive devices and techniques, the diagnosis and treatment have witnessed major changes, such as the use of laparoscopic surgery in some cases to achieve minimally invasive treatment. However, strict adherence to the indications and contraindications is still required. PMID:25489584

    Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Chest Trauma in athletes is a common health problem. However, myocardial infarction secondary to coronary dissection in the setting of blunt chest trauma is extremely rare. We report a case of acute inferior wall myocardial infarction following blunt chest trauma. A 32-year-old male with no relevant medical problems was transferred to our medical center for retrosternal chest pain after being elbowed in the chest during a soccer game. Few seconds later, he started experiencing sharp retrosternal chest pain that was severe to that point where he called the emergency medical service. Upon arrival to the trauma department patient was still complaining of chest pain. ECG demonstrated ST segment elevation in the inferior leads with reciprocal changes in the lateral leads all consistent with active ischemia. After rolling out aortic dissection, patient was loaded with ASA, ticagerlor, heparin and was emergently taken to the cardiac catheterization lab. Coronary angiography demonstrated 100% thrombotic occlusion in the distal right coronary artery with TIMI 0 flow distally. After thrombus aspiration, a focal dissection was noted on the angiogram that was successfully stented. Two days after admission patient was discharged home. Echocardiography prior to discharge showed inferior wall akinesis, normal right ventricular systolic function and normal overall ejection fraction.

    Retroperitoneal fibrosis is a rare fibrosing reactive process that may be confused with mesenteric fibromatosis. Abdominal aorta aneurysm is rare too and mostly develops secondary to Behcet's disease, trauma, and infection or connective tissue diseases. Incidence of aneurysms occurring as a result of atherosclerotic changes increases in postmenopausal period. Diagnosis can be established with arteriography, tomography, or magnetic resonance imaging associated with clinical findings. Tumors and cysts should be considered in differential diagnosis. Abdominal ultrasound and contrast-enhanced computerized tomography revealed an infrarenal abdominal aorta aneurysm in a 41-year-old woman, but, on surgery, retroperitoneal fibrosis surrounding the aorta was detected. We present this interesting case because retroperitoneal fibrosis encircling the abdominal aorta can mimic abdominal aorta aneurysm radiologically.

    The fiftieth anniversary of the death by assassination of President John Kennedy is an opportunity to pay homage to his memory and also reflect on the important role plastic surgeons have played in the management of trauma. That reflection included a hypothetical scenario, a discussion of the surgical treatment of Kennedy (if he survived) and Governor Connally. The scenario describes the management of cranioplasty in the presence of scalp soft-tissue contracture, reconstruction of the proximal trachea, reconstitution of the abdominal wall, and restoration of a combined radius and soft-tissue defect. The development of diagnostic and therapeutic advances over the past 50 years in the care of maxillofacial trauma is described, including the evolution of imaging, timing of surgery, and operative techniques. Finally, contemporary measures of triage in situations involving mass casualties, as in the Boston Marathon bombings, complete the dedication to President Kennedy.

    A two-year-old cat was involved in a road traffic accident. Survey abdominal radiographs and urinary function were considered unremarkable. Six weeks later the cat presented with a palpable dorsal abdominal mass. Radiography revealed a soft tissue opacity mass caudal to the right kidney. Ultrasonography revealed a cyst-like structure with moderately echogenic contents, and right-sided hydronephrosis. There was no excretion of contrast medium from the right kidney after intravenous urography. Surgery revealed a disrupted right ureter adherent to the retroperitoneal mass. The mass contained serosanguineous fluid consistent with extravasated urine. Ureteronephrectomy was performed. The majority of the mass was excised and the cavity ablated. Histopathology of the excised tissue revealed a thick fibrous wall with no epithelial lining, consistent with a urinoma, which is thought to have developed as a consequence of ureteral trauma. The cat was clinically well three months postoperatively.

    Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7%) males and 20 (18.3%) females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years). The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%), colon 48 (44%), and liver 41 (37.6%). Forty-four (40.4%) patients had extra-abdominal injuries involving the chest in 17 (15.6%), musculoskeletal 12 (11%), and the head in 9 (8.3%). The most prevalent weapon injuries were gunshot 76 (69.7%), explosives 12 (11%), stab injuries 11 (10.1%), and blunt abdominal trauma 10 (9.2%). The injury severity score varied from 8 to 52 (mean: 20.8) with a fatality rate of 11 (10.1%) and morbidity rate of 29 (26.6%). Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems. PMID:26957819

    Salsac, Anne-Virginie

    2005-03-01

    The changes in the spatial and temporal distribution of the WSS and gradients of WSS during the enlargement of AAAs are important to understand the etiology and progression of this vascular disease, since they affect the wall structural integrity, primarily via the changes induced on the shape, functions and metabolism of the endothelial cells. PIV measurements were performed in aneurysm models, while changing systematically their size and geometry. Two regions with distinct patterns of WSS were identified. The region of flow detachment extends over the proximal half and is characterized by oscillatory WSS of very low mean. The region of flow reattachment, located distally, is dominated by large, negative WSS and sustained gradients of WSS that result from the impact of the vortex ring on the wall. Cultured EC were subjected to these two types of stimuli in vitro. The permeability of the endothelium was found to be largely increased in the flow detachment region. Endothelium cell-cell adhesion, proliferation and apoptosis were also affected by the high gradients of WSS.

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    It has been previously reported that trauma patients with cirrhosis undergoing emergency abdominal operations exhibit a fourfold increase in mortality independent of their Child's classification. We undertook this review to assess the impact of cirrhosis on trauma patients. We reviewed the records of patients from 1993 to 2003 with documented hepatic cirrhosis and compared them to a 2:1 control population without hepatic cirrhosis and matched for age, sex, Injury Severity Score (ISS), and Glasgow Coma Score (GCS). Demographic, severity of injury, and outcome data were recorded. Student's t test and X2 were used for statistical analysis and a P < 0.05 was significant. Sixty-one patients had documented cirrhosis and were compared to 156 matched controls. Comparing the two groups demonstrates there was no difference in age, ISS, or GCS. Intensive care stay, hospital length of stay, blood requirements in the first 24 hours postinjury, and mortality (33% vs 1%) was significantly greater in the trauma patients with cirrhosis. Fifty-five per cent of deaths in the cirrhosis group was due to sepsis, and, as the Child's class increases, so does the mortality (Child's A, 15%; B, 37%; and C, 63%). In 64 per cent of cirrhotics without an emergent abdominal operation, mortality was 21 per cent. In the 36 per cent of cirrhotics who had emergent abdominal operation, mortality was 55 per cent. Hepatic cirrhosis in trauma patients, regardless of severity of injury or the need for an abdominal intervention, is a poor prognostic indicator. The necessity of an abdominal operative intervention further amplifies this effect. Trauma and cirrhosis is, in fact, a deadly duo.

    The skin between the mastectomy scar and the future infra-mammary fold may be managed in different ways in delayed breast reconstruction using a DIEP (deep inferior epigastric perforator). Conserving this skin and positioning the flap skin paddle in the middle of the breast usually highlights skin color disparity because of two visible transition zones. Resection of the entire skin under the scar may be more aesthetic but limits direct closure possibility in case of flap failure. In order to benefit from both aesthetic result and safe surgical method, we propose the abdominal drop flap. The inferior thoracic skin flap is detached from the thoracic wall beyond the future infra-mammary fold, preserved and pushed under the breast.

    Suspension trauma (also known as “harness‐induced pathology” or “orthostatic shock while suspended”) is the development of presyncopal symptoms and loss of consciousness if the human body is held motionless in a vertical position for a period of time. It has been described in experiments of personal fall protection, and has been implicated in causes of death in mountaineering accidents, but it seems neither to be widely known about nor to have been presented to the medical profession. This article highlights the potential existence of suspension trauma and suggests that more robust medical research using modern harnesses and healthy volunteers would be beneficial to assess whether this is purely a theoretical risk.

    In a review of over 300 CT scans of abdominal trauma, we encountered 13 patients with surgically proved pancreatic injuries. CT correctly diagnosed pancreatic fractures, contusions, or posttraumatic pseudocysts in 11 of these patients. There were two false positive and two false negative diagnoses. The CT diagnosis of pancreatic trauma may be difficult in selected patients who are scanned soon after injury. Acutely, the actual plane of a pancreatic fracture may be difficult to identify with CT, and the peripancreatic soft-tissue changes of traumatic pancreatitis are often subtle. Eight of 11 correctly diagnosed pancreatic injuries showed thickening of the left anterior renal fascia on CT scans. This sign should prompt a critical evaluation of the pancreas of the traumatized patient.

    Radiologists play an important role in evaluation of geriatric trauma patients. Geriatric patients have injury patterns that differ markedly from those seen in younger adults and are susceptible to serious injury from minor trauma. The spectrum of trauma in geriatric patients includes head and spine injury, chest and rib trauma, blunt abdominal injury, pelvic fractures, and extremity fractures. Clinical evaluation of geriatric trauma patients is difficult because of overall frailty, comorbid illness, and medication effects. Specific attention should be focused on the effects of medications in this population, including anticoagulants, steroids, and bisphosphonates. Radiologists should use age-appropriate algorithms for radiography, computed tomography (CT), and magnetic resonance imaging of geriatric trauma patients and follow guidelines for intravenous contrast agent administration in elderly patients with impaired renal function. Because there is less concern about risk for cancer with use of ionizing radiation in this age group, CT is the primary imaging modality used in the setting of geriatric trauma. Clinical examples are provided from the authors' experience at a trauma center where geriatric patients who have sustained major and minor injuries are treated daily. PMID:26065932

  19. Toxic trauma.

    Hazardous materials (HAZMAT) carry many inherent dangers. Such materials are distributed widely in industrial and military sites. Toxic trauma (TT) denotes the complex of systemic and organ injury caused by toxic agents. Often, TT is associated with other injuries that also require the application of life-support techniques. Rapid onset of acute respiratory failure and consequent cardiovascular failure are of primary concern. Management of TT casualties is dependent upon the characteristics of the toxic agents involved and on the demographics surrounding the HAZMAT incident. Agents that can produce TT possess two pairs of salient characteristics: (1) causality (toxicity and latency), and (2) EMS system (persistency and transmissibility). Two characteristics of presentations are important: (1) incident presentation, and (2) casualty presentation. In addition, many of these agents complicate the processes associated with anaesthesia and must be dealt with. Failure of recognition of these factors may result in the development of respiratory distress syndromes and multiorgan system failure, or even death. PMID:11513285

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents.

    2014-01-01

    Abdominal hernias are common with over 20 million hernia repairs performed worldwide. Inguinal hernias are the most common type of hernia. Inguinal and sports hernia have been discussed at length in recent literature, and therefore, they will not be addressed in this article. The noninguinal hernias are much less common but do occur, and knowledge of these hernias is important when assessing the athlete with abdominal pain. Approximately 25% of abdominal wall hernias are noninguinal, and new data show the order of frequency as umbilical, epigastric, incisional, femoral, and all others (i.e., Spigelian, obturator, traumatic). Return-to-play guidelines need to be tailored to the athlete and the needs of their sport. Using guidelines similar to abdominal strain injuries can be a starting point for the treatment plan. Laparoscopic repair is becoming more popular because of safety and efficacy, and it may lead to a more rapid return to play. PMID:24614421

    Complex anatomical relation of the duodenum, pancreas, biliary tract, and major vessels plays to obscure pancreaticoduodenal injuries. Causes of pancreaticoduodenal injuries are blunt trauma (traffic accidents, sport injuries) in 25 % of cases and penetrating abdominal injuries (stab wounds and firearm injuries) in 75 % of cases. Duodenal injuries are reported to occur in 0.5 to 5 % of all abdominal trauma cases and are observed in 11 % of abdominal firearm wounds, 1.6 % of abdominal stab wounds, and 6 % of blunt trauma. Retroperitoneal and deep abdominal localization of duodenum as an organ contribute to the difficulty in diagnosis and treatment. There are three important major points regarding treatment of duodenal injuries: (1) operation timing and decision, (2) Intraoperative detection, and (3) post-operative care. Therefore, it is difficult to diagnose and treat duodenal trauma. We would like to present a 21-year-old male patient with pancreaticoduodenal injury who presented to our emergency service after firearm injury to his abdomen and discuss his treatment with a short review of related literature.

    People experiencing blunt thoracic trauma may sustain multiple rib fractures, flail chest, cardiac or pulmonary contusions, injury to the great vessels, sternal fractures, clavicular fractures, neck injuries, and lacerations of the liver and/or spleen. Long-term sequelae from blunt chest trauma include chest wall deformities, persistent dyspnea, and cardiac, neurologic, or esophageal complications. Chronic pain, depression, and loss of functional status are also frequent components of recovery from trauma. PMID:12025303

  5. Penetrating ocular trauma associated with blank cartridge

    PubMed Central

    2014-01-01

    Background Blank cartridge guns are generally regarded as being harmless and relative safe. However recent published articles demonstrated that the gas pressure from the exploding propellant of blank cartridge is powerful enough to penetrate the thoracic wall, abdominal muscle, small intestine and the skull. And there has been a limited number of case reports of ocular trauma associated with blank cartridge injury. In addition, no report on case with split extraocular muscle injury with traumatic cataract and penetrating corneoscleral wound associated with blank cartridge has been previously documented. This report describes the case of patient who sustained penetrating ocular injury with extraocular muscle injury by a close-distance blank cartridge that required surgical intervention. Case presentation A 20-year-old man sustained a penetrating globe injury in the right eye while cleaning a blank cartridge pistol. His uncorrected visual acuity at presentation was hand motion and he had a flame burn of his right upper and lower lid with multiple missile wounds. On slit-lamp examination, there was a 12-mm laceration of conjunctiva along the 9 o'clock position with two pinhole-like penetrating injuries of cornea and sclera. There was also a 3-mm corneal laceration between 9 o'clock and 12 o'clock and the exposed lateral rectus muscle was split. Severe Descemet's membrane folding with stromal edema was observed, and numerous yellow, powder-like foreign bodies were impacted in the cornea. Layered anterior chamber bleeding with traumatic cataract was also noted. Transverse view of ultrasonography showed hyperechoic foreign bodies with mild reduplication echoes and shadowing. However, a computed tomographic scan using thin section did not reveal a radiopaque foreign body within the right globe. Conclusion To our best knowledge, this is the first case report of split extraocular muscle injury with traumatic cataract and penetrating ocular injury caused by blank cartridge

    Abdominal cerebrospinal fluid pseudocyst in an infrequent complication of ventriculoperitoneal (VP) shunts. We reviewed ten patients with abdominal pseudocyst. There were five girls and five boys, aged between 4 months and 14 years. The number of shunt procedures prior to the presentation varied between one and five. Only one patient had had a previous shunt infection. No patients had undergone prior abdominal surgery other than VP shunting. The time from the last shunting procedure to the development of abdominal pseudocyst ranged from 3 weeks to 5 years. Presenting symptoms and signs were mainly related to abdominal complaints in all patients. Three patients also had signs of shunt malfunction. The diagnosis was made by ultrasound in all patients. Shunt infection was determined in six patients. Repositioning if the peritoneal catheter seemed to have a higher rate of recurrence. The diagnosis of abdominal pseudocyst should be considered in VP-shunted patients presenting with abdominal complaints.

    The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects. PMID:27016167

    Objectives The purpose of this study was to review radiological images of patients with Paragonimus westermani (PW) that simultaneously involved the chest and abdomen. Methods Our study included four patients with serologically and histopathologically confirmed paragonimiasis. Abdomen CT (n=3) and chest CT (n=3) scans were available, and abdominal wall ultrasonography was performed in all patients. We retrospectively reviewed the clinical, radiological and histopathological findings of these patients. Results The most common abdominal CT findings were ascites and intraperitoneal or abdominal wall nodules. Low-attenuated serpentine lesions of the liver were another common and relatively specific feature. Conclusion Radiologists should consider the possibility of PW when these abdominal CT findings are noted, especially with pleural effusion or subpleural nodules in patients with initial abdominal symptoms.

    2011-07-01

    Cardiopulmonary dysfunction and failure are commonly encountered in the patient with intra-abdominal hypertension (IAH) or abdominal compartment syndrome. Accurate assessment and optimization of preload, contractility, and afterload in conjunction with appropriate goal-directed resuscitation and assessment of fluid responsiveness are essential to restore end-organ perfusion. In patients with IAH, the traditional "barometric" preload indicators such as pulmonary artery occlusion pressure and central venous pressure are erroneously increased. Volumetric monitoring techniques have been proven to be superior in directing the appropriate resuscitation together with targeted abdominal perfusion pressure. If such limitations are not recognized, misinterpretation of the patient's cardiac status is likely, resulting in inappropriate and potentially detrimental therapy. IAH also markedly affects the mechanical properties of the chest wall and consequently also the respiratory function. Altered mechanical properties of the chest wall may limit ventilation, influence the work of breathing, affect the interaction between the respiratory muscles, hasten the development of respiratory failure, and interfere with gas exchange. Pulmonary monitoring is important to understand the relationships between intra-abdominal pressure and chest wall mechanics and the impact of IAH on ventilator-induced lung injury, lung distention, recruitment, and lung edema.

    Mesenteric trauma is one of the possible injuries caused by the use of seat belts in case of motor vehicle crash. We report here a rare case of rectal bleeding by rupture of a mesosigmoid haematoma. An emergent laparotomy revealed a mesosigmoid haematoma with a centimetric rectal perforation. The wearing of safety belts added some specific blunt abdominal trauma, which directly depends on lap-and-sash belts. Mesenteric injuries are found out up to 5% of blunt abdominal traumas. "Seat belt mark" leads the surgical team to strongly suspect an intra-abdominal trauma. When "seat belt mark" sign is found, in patients with mild to severe blunt car injuries, CT-scan has to be realised to eliminate intra-abdominal complications, including mesenteric and mesosigmoid ones. In case of proved mesenteric haematoma associated to intestinal bleeding, a surgical treatment must be considered as first choice. Conservative approach remains possible in stable patients but surgical exploration remains necessary in unstable patients with active bleeding. PMID:20638207

    Background Impalement injury is an uncommon presentation in the emergency department (ED), and penetrating thoraco-abdominal injuries demand immediate life-saving measures and prompt care. Massive penetrating trauma by impalement in a pediatric case represents a particularly challenging presentation for emergency providers in non-trauma center settings. Case presentation We report a case of 10 year old male who presented in our ED with an alleged history of fall from an approximately 15 foot tall coconut tree, landing over an upright bamboo stake approximately 50 centimeter long, resulting in a trans-abdomino, trans-thoracic injury. In addition to prompt resuscitation and hospital transfer, assessment of damage to vital structures in conjunction with surgical specialty consultation was an immediate goal. Conclusion This article describes a case study of an impalement injury, relevant review of the available literature, and highlights the peculiar strategies required in the setting of a resource limited ED.

    Postmortem computed tomography (PMCT) has become an important complement in investigating forensic cases allowing an accurate detection of gas accumulations. The present study investigated the presence and distribution of gas in a large number of non-putrefied cases of traumatic and non-traumatic deaths. Furthermore the possibility of pneumobilia secondary to blunt abdominal trauma was studied. Retrospectively, 73 cases, underwent a whole-body PMCT prior to autopsy. These were divided into four groups: penetrating trauma (20 gunshot cases, 13 stabbing cases), blunt abdominal trauma (20 cases) and a control group of 20 non-trauma cases. Exclusion criteria were visible signs of decomposition. Each group was screened for gas accumulations in the vascular system, internal organs, soft tissues and body cavities. Gas accumulations were present in 98% of the trauma cases, compared to 80% of the control group. The most affected structures and/or organs in the trauma group were soft tissues, vessels and the liver. In most cases of the trauma group gas was associated with open injuries and lacerations of vessels. Furthermore, in the gunshot group gas was frequently seen in the intracranial cavity. Pneumobilia occurred in one case of the blunt trauma group; in that control group gas was also seen, but less frequently. Gas accumulation showed a strong association with traumatic events, but even the majority of non-trauma cases showed gas accumulations. Despite the exclusion of cases with visible decomposition signs, a putrefactive origin of gas was assumed in some cases. Gas accumulations are a frequent finding in PMCT with a higher incidence in (open) trauma cases. Even though a differentiation between putrefactive and traumatic gas accumulations is still difficult, knowledge of the circumstance surrounding the case may help identify the origin of gas.

  13. Endoscopic treatment of spinal trauma at the thoracolumbar junction

    2007-01-01

    Attempts of treating unstable fractures of the thoracolumbar junction by posterior reduction and fixation alone often result in a significant loss of correction, especially in lesions where a severe destruction of the vertebral body and the intervertebral disc is present. The conventional open approaches like classic thoraco-phreno-lumbotomy produces additional iatrogenic trauma at the lateral chest and abdominal wall which not rarely leads to intercostal neuralgia, as well as post-thoracotomy syndromes. The endoscopic trans-diaphragmatic approach described below opens up the whole thoracolumbar junction to a minimally invasive procedure allowing one to perform all the procedures needed for a full reconstruction of the anterior column of the spine like corpectomy, decompression, vertebral body replacement and anterior plating. The key to address also the subdiaphragmal and retroperitoneal section of the thoracolumbar junction is a partial detachment of the diaphragm which runs along the attachment at the spine and the ribs. The technique was published first in 1998 and has been used now in 650 endoscopic procedures at the thoracolumbar junction out of a total of more than 1300 thoracoscopic operations of the spine in the BG Unfallklinik Murnau, Germany since 1996.

  14. Abdominal aortic aneurysm.

    PubMed

    Keisler, Brian; Carter, Chuck

    2015-04-15

    Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease). There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. Surgical intervention by open or endovascular repair is the primary option and is typically reserved for aneurysms 5.5 cm in diameter or greater. There are limited options for medical treatment beyond risk factor modification. Ruptured abdominal aortic aneurysm is a medical emergency presenting with hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. It is associated with high prehospitalization mortality. Emergent surgical intervention is indicated for a rupture but has a high operative mortality rate. PMID:25884861

    Blunt trauma to the epigastrium is becoming an increasingly important cause of injury and may result in retroperitoneal haematoma involving the head of the pancreas as well as the descending duodenum. Ultrasound seems to be of great advantage in the diagnosis of the effects and complications of blunt abdominal trauma such as obstruction of the biliary tree, the gastric outlet and the inferior vena cava. Direct involvement of the descending duodenum seems to be relatively uncommon, intramural haematoma of the duodenum is described only rarely in the literature. Three additional cases of intramural haematoma of the duodenum are reported with particular reference to the recent literature.

    Examination of 119 patients with abdominal tuberculosis permitted the description of the characteristic semiotics of the illness. Today the patients with abdominal tuberculosis are mainly women of child-bearing age with a long-term tuberculosis catamnesis and intoxication, with a history of tuberculosis of different sites, those suffering from tuberculosis or its sequels at present (64%), those with pains (94%), discomfort or swelling of the abdomen (79%), malfunction of the gastrointestinal tract (65%), weight loss (86%), malnutrition (72%), anemia (63%), not infrequently with inflammatory induration (43%) or ascites in the abdominal cavity (39%). In addition to this characteristic semiotics, the patients with abdominal tuberculosis may demonstrate the most different and unexpected symptoms up to acute abdomen (23%). To make differential diagnosis of abdominal tuberculosis, one has often to resort to diagnostic laparotomy, laparoscopy, Koch's test and to trial therapy.

    There is overlap between general, abdominal and vascular surgery on one hand and plastic surgery on the other hand, e.g., in hernia surgery, in particular, recurrent hernia, reconstruction of the abdominal wall or defect closure after abdominal or vascular surgery. Bariatric operations involve both special fields too. Plastic surgeons sometimes use skin and muscle compartments of the abdominal wall for reconstruction at other regions of the body. This article aims to i) give an overview about functional, anatomic and clinical aspects as well as the potential of surgical interventions in plastic surgery. General/abdominal/vascular surgeons can benefit from this in their surgical planning and competent execution of their own surgical interventions with limited morbidity/lethality and an optimal, in particular, functional as well as aesthetic outcome, ii) support the interdisciplinary work of general/abdominal/vascular and plastic surgery, and iii) provide a better understanding of plastic surgery and its profile of surgical interventions and options.

We used a cross-sectional study of abdominal masses in children attending a university teaching hospital. The common abdominal masses were: Wilms' tumour, 12 (14.8%); lymphoma, 11 (13.6%); appendiceal mass/abscess, 11 (13.6%); neuroblastoma, 7 (8.6%); TB, 6 (7.4%); hydronephrosis, 5 (6.2%); abdominal wall abscess, 6 (7.4%); hydatidcyst, 4 (4.9%); mesenteric cyst, 3 (3.7%); and intussusceptions, 3 (3.7%). Identification of a purely cystic mass was suggestive of benign lesion (odds ratio [OR] = 118, P = 0.0001) and masses found in the <5 years age group tend to be malignant (OR = 2.77). The most common sites of origin were kidneys, retroperitoneal extra renal and gastrointestinal tract. The overall diagnostic accuracy of ultrasound was 88.9%.

    Although trauma exposure is common, few people develop acute and chronic psychiatric disorders. Those who develop posttraumatic stress disorder likely have coexisting psychiatric and physical disorders. Psychiatric nurses must be knowledgeable about trauma responses, implement evidence-based approaches to conduct assessments, and create safe environments for patients. Most researchers assert that trauma-focused cognitive-behavioral approaches demonstrate the most efficacious treatment outcomes. Integrated approaches, offer promising treatment options.

    Chest trauma is one important factor for total morbidity and mortality in traumatized emergency patients. The complexity of injury in trauma patients makes it challenging to provide an optimal oxygenation while protecting the lung from further ventilator-induced injury to it. On the other hand, lung trauma needs to be treated on an individual basis, depending on the magnitude, location and type of lung or chest injury. Several aspects of ventilatory management in emergency patients are summarized herein and may give the clinician an overview of the treatment possibilities for chest trauma victims. PMID:21769213

    The introduction of laparoscopy has provided trauma surgeons with a valuable diagnostic and, at times, therapeutic option. The minimally invasive nature of laparoscopic surgery, combined with potentially quicker postoperative recovery, simplified wound care, as well as a growing number of viable intraoperative therapeutic modalities, presents an attractive alternative for many traumatologists when managing hemodynamically stable patients with selected penetrating and blunt traumatic abdominal injuries. At the same time, laparoscopy has its own unique complication profile. This article provides an overview of potential complications associated with diagnostic and therapeutic laparoscopy in trauma, focusing on practical aspects of identification and management of laparoscopy-related adverse events.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

  7. Optical modeling toward optimizing monitoring of intestinal perfusion in trauma patients

    2013-01-01

    Trauma is the number one cause of death for people between the ages 1 and 44 years in the United States. In addition, according to the Centers of Disease Control and Prevention, injury results in over 31 million emergency department visits annually. Minimizing the resuscitation period in major abdominal injuries increases survival rates by correcting impaired tissue oxygen delivery. Optimization of resuscitation requires a monitoring method to determine sufficient tissue oxygenation. Oxygenation can be assessed by determining the adequacy of tissue perfusion. In this work, we present the design of a wireless perfusion and oxygenation sensor based on photoplethysmography. Through optical modeling, the benefit of using the visible wavelengths 470, 525 and 590nm (around the 525nm hemoglobin isobestic point) for intestinal perfusion monitoring is compared to the typical near infrared (NIR) wavelengths (805nm isobestic point) used in such sensors. Specifically, NIR wavelengths penetrate through the thin intestinal wall (~4mm) leading to high background signals. However, these visible wavelengths have two times shorter penetration depth that the NIR wavelengths. Monte-Carlo simulations show that the transmittance of the three selected wavelengths is lower by 5 orders of magnitude depending on the perfusion state. Due to the high absorbance of hemoglobin in the visible range, the perfusion signal carried by diffusely reflected light is also enhanced by an order of magnitude while oxygenation signal levels are maintained. In addition, short source-detector separations proved to be beneficial for limiting the probing depth to the thickness of the intestinal wall.

  8. Diagnostic peritoneal lavage in evaluating acute abdominal pain.

    1975-06-01

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Patient records were retrospectively analyzed to elucidate the characteristics of patients with colorectal cancer (CRC) diagnosed with screening abdominal ultrasound (US). Patients diagnosed with CRC using abdominal US [localized irregular wall thickening (W) or a hypoechoic mass with a hyperechoic mass (M)] were enrolled. The patients were subjected to colonoscopy and treated surgically between March, 2010 and January, 2015. A total of 5 men (aged 74.0±0.8 years) and 10 women (aged 73.0±12.0 years) were analyzed. Stratification was analyzed with abdominal US. The threshold value of wall thickness to diagnose CRC was investigated with receiver operating characteristic (ROC) curve analysis. The average wall thickness was 2.8±0.4 mm in the surrounding normal tissue and 12.7±5.2 mm in CRC (one-way analysis of variance, P<0.0001). The wall was significantly thicker in CRC compared with the normal colonic wall. The calculated threshold value was 4.3 mm for the diagnosis of CRC. Stratification was preserved in W, while it was lost in M (Chi-squared test, P=0.0196). The hemoglobin concentration was lower, while the C-reactive protein, carcinoembryonic antigen and carbohydrate antigen 19-9 levels were elevated above normal values. The threshold value was 4.3 mm for the diagnosis of CRC with abdominal US. PMID:27330768

    The abdominal actinomycosis (AA) is a rare and often unrecognised suppurative chronic illness. It is caused by an anaerobic Gram positive bacteria, Actinomyces israelii. Abdominal actinomycosis is responsible for pseudotumoral syndrome often leading, to a large and mutilating surgery whereas a prolonged treatment by antibiotics would have permitted to cure the disease. The diagnosis is obtained generally from anatomopathologic exam. We report four cases of abdominal actinomycosis being revealed by a pseudotumoral syndrome. The diagnosis was only made after surgery. In spite of an active treatment by antibiotics during several months, two of our patients had a relapse of the infectious process. These four observations confirm the diagnostic and therapeutic difficulties previously reported by other authors.

    2015-11-01

    Acute disorders of the abdominal aorta are potentially lethal conditions that require prompt evaluation and treatment. Computed tomography (CT) is the primary imaging method for evaluating these conditions because of its availability and speed. Volumetric CT acquisition with multiplanar reconstruction and three-dimensional analysis is now the standard technique for evaluating the aorta. MR imaging may be useful for select applications in stable patients in whom rupture has been excluded. Imaging is indispensable for diagnosis and treatment planning, because management has shifted toward endoluminal repair. Acute abdominal aortic conditions most commonly are complications of aneurysms and atherosclerosis. PMID:26526434

    2016-08-01

    Abdominal trauma accounts for nearly 20% of all traumatic injuries. It often involves young patients sustaining multiple injuries, with a high associated mortality rate. Management should begin at the scene of injury and relies on a structured chain of care in order to transport the trauma patient to the appropriate hospital center. Management is multi-disciplinary, involving intensive care specialists, surgeons and radiologists. Imaging to precisely define injury is best performed with whole body dual phase computed tomography, which can also identify the source of bleeding. Non-operative management has developed considerably over the years: this includes selective embolization in case of active bleeding or vascular anomalies in stable or stabilized patients after resuscitation. Embolization has become one of the corner stones of abdominal trauma management and interventional radiologists must play an active role on the trauma team. This overview details the different embolization procedures according to the involved organ and embolic agent used. PMID:27374109

    In the pediatric population, abdominal compartment syndrome (ACS) is a known complication of abdominal wall defect repair. However, there are only few reports on ACS in newborns and only a proposal of critical intra-abdominal pressure value (IAP) in term newborns, absent in preterm newborns. Although the prevalent clinical sign is tense abdominal distension, it may be difficult to distinguish ACS from pathologies that will not require decompression. The purpose of this study was to identify predictors for ACS and therefore morbidity or mortality indicators. We reviewed newborns presenting with tense abdominal distension and end organ failure. Anamnestic, clinical, laboratory, and instrumental investigations were analyzed to extrapolate predictors. Outcomes were compared with a control group. The incidence of ACS in our neonatal intensive care unit was 5% in the overall population of babies, 16% in tracheal-ventilated newborns, and 57% in infants with abdominal wall defects. We found that, with onset of acidosis or high gastric residuals, the lactate values will be predictive for mortality. We can also suggest paying particular attention to high lactate values just at the onset of distension, in infants with more advanced gestational age, with previously surgical repair, to determine early surgical intervention independently of a specific IAP measurement.

    Imaging is an indispensable part of the initial assessment and subsequent management of patients with head trauma. Initially, it is important for diagnosing the extent of injury and the prompt recognition of treatable injuries to reduce mortality. Subsequently, imaging is useful in following the sequelae of trauma. In this chapter, we review indications for neuroimaging and typical computed tomography (CT) and magnetic resonance imaging (MRI) protocols used in the evaluation of a patient with head trauma. We review the role of CT), the imaging modality of choice in the acute setting, and the role of MRI in the evaluation of patients with head trauma. We describe an organized and consistent approach to the interpretation of imaging of these patients. Important topics in head trauma, including fundamental concepts related to skull fractures, intracranial hemorrhage, parenchymal injury, penetrating trauma, cerebrovascular injuries, and secondary effects of trauma, are reviewed. The chapter concludes with advanced neuroimaging techniques for the evaluation of traumatic brain injury, including use of diffusion tensor imaging (DTI), functional MRI (fMRI), and MR spectroscopy (MRS), techniques which are still under development.

    The musculoskeletal structures of the thoracic wall and the neck are a relatively common source of chest pain. Pain arising from these structures is often mistaken for angina pectoris, pleurisy or other serious disorders. In this article the clinical features, pathogenesis and management of the various musculoskeletal chest wall disorders are discussed. The more common causes are costochondritis, traumatic muscle pain, trauma to the chest wall, “fibrositis” syndrome, referred pain, psychogenic regional pain syndrome, and arthritis involving articulations of the sternum, ribs and thoracic spine. Careful analysis of the history, physical findings and results of investigation is essential for precise diagnosis and effective treatment. ImagesFig. 3Fig. 4Fig. 5 PMID:4027804

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

    BACKGROUND: Medical operations on the International Space Station will emphasize the stabilization and transport of critically injured personnel and so will need to be capable of advanced trauma life support (ATLS). METHODS: We evaluated the ATLS invasive procedures in the microgravity environment of parabolic flight using a porcine animal model. Included in the procedures evaluated were artificial ventilation, intravenous infusion, laceration closure, tracheostomy, Foley catheter drainage, chest tube insertion, peritoneal lavage, and the use of telemedicine methods for procedural direction. RESULTS: Artificial ventilation was performed and appeared to be unaltered from the 1-G environment. Intravenous infusion, laceration closure, percutaneous dilational tracheostomy, and Foley catheter drainage were achieved without difficulty. Chest tube insertion and drainage were performed with no more difficulty than in the 1-G environment due to the ability to restrain patient, operator and supplies. A Heimlich valve and Sorenson drainage system were both used to provide for chest tube drainage collection with minimal equipment, without the risk of atmospheric contamination, and with the capability to auto-transfuse blood drained from a hemothorax. The use of telemedicine in chest tube insertion was demonstrated to be useful and feasible. Peritoneal lavage using a percutaneous technique, although requiring less training to perform, was found to be dangerous in weightlessness due to the additional pressure of the bowel on the anterior abdominal wall creating a high risk of bowel perforation. CONCLUSIONS: The performance of ATLS procedures in microgravity appears to be feasible with the exception of diagnostic peritoneal lavage. Minor modifications to equipment and techniques are required in microgravity to effect surgical drainage in the presence of altered fluid dynamics, to prevent atmospheric contamination, and to provide for the restraint requirements.

    Mouse bladder wall injection is a useful technique to orthotopically study bladder phenomena, including stem cell, smooth muscle, and cancer biology. Before starting injections, the surgical area must be cleaned with soap and water and antiseptic solution. Surgical equipment must be sterilized before use and between each animal. Each mouse is placed under inhaled isoflurane anesthesia (2-5% for induction, 1-3% for maintenance) and its bladder exposed by making a midline abdominal incision with scissors. If the bladder is full, it is partially decompressed by gentle squeezing between two fingers. The cell suspension of interest is intramurally injected into the wall of the bladder dome using a 29 or 30 gauge needle and 1 cc or smaller syringe. The wound is then closed using wound clips and the mouse allowed to recover on a warming pad. Bladder wall injection is a delicate microsurgical technique that can be mastered with practice.

    Violence has impacted every aspect of daily life. These tragedies have shocked the world. This has resulted in school communities being fractured. Additionally, The National Survey of Children Exposed to Violence found that 60% of the children surveyed have been exposed to some form of trauma, either in or out of school. Traumatology research has shown most people respond to a wide range of traumatic events in similar ways. The common responses include traumatic responses, posttraumatic stress responses, and posttraumatic stress disorder (PTSD). In this article the authors outline the impact of trauma on children within school systems; discuss the mental health services schools are providing; present a trauma-informed school model; identifies tools which can be utilized in schools; and provide resources needed for a trauma-informed school, along with additional tools and resources. The authors discuss future recommendations for the community and schools as traumatic events continue to grow and impact a large number of children.

  6. Review of pancreatic trauma.

    1989-01-01

    In reviewing the literature on pancreatic trauma (1,984 cases), I found that it resulted from penetrating trauma in 73% and blunt trauma in 27% of cases. Associated injuries were common (average 3.0 per patient). Increased mortality was associated with shotgun wounds, an increasing number of associated injuries, the proximity of the injury to the head of the pancreas, preoperative shock, and massive hemorrhage. High mortality was found for total pancreatectomy, duct reanastomosis, and lack of surgical treatment, with lower mortality for Roux-en-Y anastomoses, suture and drainage, distal pancreatectomy, and duodenal exclusion and diverticulization techniques. Most patients required drainage only. The preoperative diagnosis of pancreatic trauma is difficult, with the diagnosis usually made during surgical repair for associated injuries. Blood studies such as amylase levels, diagnostic peritoneal lavage, and plain radiographs are not reliable. Computed tomographic scanning may be superior, but data are limited. PMID:2669347

    Overall mortality ascribable to multiple traumas, that in Italy is responsible for about 8,000 death/year, is strictly dependent on the function of the so called Trauma Care System. This study reports on an epidemiological survey conducted in the urban area of Florence along a 23-month period (from Jan 97 to Nov 99), with the aim to identify the typology of traumas and the first aid care delivered to the person until hospital admission. These data were compared to those collected in the urban area of Bologna because the composition of the first-aid team is different, being nurses, in Bologna, an integral component of the first aid system. On a total of 118 multiple traumas, 17% was represented by isolated head trauma, while in 72% involvement of other organs was present in addition to the head; 11% of cases were abdominal or thoracic traumas, 1% of lower extremities. In 46% the cause of trauma was a car accident. The complexity of care delivered to the person with trauma was less in the Florence survey, as indicated by the immobilization of patients, performed in only 11% of cases as compared to 47% in Bologna, by the application of the cervical collar, applied in 12% versus 62% of traumas. Although the two samples are not strictly comparable, these data suggest that the presence of nurses in the Trauma Care System can be one of the elements of improvement of the quality of delivered care.

    Penetrating extremity trauma (PET) usually becomes less important when present along with multiple truncal injuries. The middle eastern wars documented the terrible mortality and morbidity resulting from PET. Even in civilian trauma, PET can lead to significant morbidity and mortality. There are now well-established principles in the evaluation and management of vascular, bony, soft tissue, and neurologic lesions that will lead to a reduction of the poor outcomes. This review will summarize some of these recent concepts.

    Traumatic disease is a major public health concern. Monitoring the quality of services provided is essential for the maintenance and improvement thereof. Assessing and monitoring the quality of care in trauma patient through quality indicators would allow identifying opportunities for improvement whose implementation would improve outcomes in hospital mortality, functional outcomes and quality of life of survivors. Many quality indicators have been used in this condition, although very few ones have a solid level of scientific evidence to recommend their routine use. The information contained in the trauma registries, spread around the world in recent decades, is essential to know the current health care reality, identify opportunities for improvement and contribute to the clinical and epidemiological research.

    2015-01-01

    Trauma patients are a diverse population with heterogeneous needs for ventilatory support. This requirement depends mainly on the severity of their ventilatory dysfunction, degree of deterioration in gaseous exchange, any associated injuries, and the individual feasibility of potentially using a noninvasive ventilation approach. Noninvasive ventilation may reduce the need to intubate patients with trauma-related hypoxemia. It is well-known that these patients are at increased risk to develop hypoxemic respiratory failure which may or may not be associated with hypercapnia. Hypoxemia in these patients is due to ventilation perfusion mismatching and right to left shunt because of lung contusion, atelectasis, an inability to clear secretions as well as pneumothorax and/or hemothorax, all of which are common in trauma patients. Noninvasive ventilation has been tried in these patients in order to avoid the complications related to endotracheal intubation, mainly ventilator-associated pneumonia. The potential usefulness of noninvasive ventilation in the ventilatory management of trauma patients, though reported in various studies, has not been sufficiently investigated on a large scale. According to the British Thoracic Society guidelines, the indications and efficacy of noninvasive ventilation treatment in respiratory distress induced by trauma have thus far been inconsistent and merely received a low grade recommendation. In this review paper, we analyse and compare the results of various studies in which noninvasive ventilation was applied and discuss the role and efficacy of this ventilator modality in trauma.

    2009-05-01

    Maintenance of a patent and prevention of aspiration are essential for the management of the trauma patient, that requires experienced physicians in airway control techniques. Difficulties of the airway control in the trauma setting are increased by the vital failures, the risk of aspiration, the potential cervical spine injury, the combative patient, and the obvious risk of difficult tracheal intubation related to specific injury related to the trauma. Endotracheal intubation remains the gold standard in trauma patient airway management and should be performed via the oral route with a rapid sequence induction and a manual in-line stabilization maneuver, to decrease the risks previously mentioned. Different techniques to control the airway in trauma patients are presented: improvement of the laryngoscopic vision, lighted stylet tracheal intubation, retrograde technique for orotracheal intubation, the laryngeal mask and the intubating laryngeal mask airways, the combitube and cricothyroidotomy. Management of the airway in trauma patients requires regular training in these techniques and the knowledge of complementary techniques allowing tracheal intubation or oxygenation to overcome difficult intubation and to prevent major complications as hypoxemia and aspiration.

    OBJECTIVE. This study examines the cost of providing trauma services in trauma centers organized by publicly administered trauma systems, compared to hospitals not part of a formal trauma system. DATA SOURCES AND STUDY SETTING. Secondary administrative discharge abstracts for a national sample of severely injured trauma patients in 44 trauma centers and 60 matched control hospitals for the year 1987 were used. STUDY DESIGN. Retrospective univariate and multivariate analyses were conducted to examine the impact of formal trauma systems and trauma center designation on the costs of treating trauma patients. Key dependent variables included length of stay, charge per day per patient, and charge per hospital stay. Key impact variables were type of trauma system and level of trauma designation. Control variables included patient, hospital, and community characteristics. DATA COLLECTION/EXTRACTION METHODS. Data were selected for hospitals based on (1) a large national hospital discharge database, the Hospital Cost and Utilization Project, 1980-1987 (HCUP-2) and (2) a special survey of trauma systems and trauma designation undertaken by the Hospital Research and Educational Trust of the American Hospital Association. PRINCIPAL FINDINGS. The results show that publicly designated Level I trauma centers, which are the focal point of most trauma systems, have the highest charge per case, the highest average charge per day, and similar or longer average lengths of stay than other hospitals. These findings persist after controlling for patient injury and health status, and for demographic characteristics and hospital and community characteristics. CONCLUSIONS. Prior research shows that severely injured trauma patients have greater chances of survival when treated in specialized trauma centers. However, findings here should be of concern to the many states developing trauma systems since the high costs of Level I centers support limiting the number of centers designated at this

    Over the past several years, abdominal single photon emission computed tomography (SPECT) imaging has evolved from a research tool to an important clinical imaging modality that is helpful in the diagnostic assessment of a wide variety of disorders involving the abdominal viscera. Although liver-spleen imaging is the most popular of the abdominal SPECT procedures, blood pool imaging is becoming much more widely utilized for the evaluation of cavernous hemangiomas of the liver as well as other vascular abnormalities in the abdomen. Adjunctive indium leukocyte and gallium SPECT studies are also proving to be of value in the assessment of a variety of infectious and neoplastic diseases. As more experience is acquired in this area, SPECT should become the primary imaging modality for both gallium and indium white blood cells in many institutions. Renal SPECT, on the other hand, has only recently been used as a clinical imaging modality for the assessment of such parameters as renal depth and volume. The exact role of renal SPECT as a clinical tool is, therefore, yet to be determined. 79 references.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

  16. Systemic inflammation after trauma.

    Lenz, Andreas; Franklin, Glen A; Cheadle, William G

    2007-12-01

    Trauma is still one of the main reasons for death among the population worldwide. Mortality occurring early after injury is due to "first hits", including severe organ injury, hypoxia, hypovolaemia or head trauma. Massive injury leads to activation of the immune system and the early inflammatory immune response after trauma has been defined as systemic inflammatory response syndrome (SIRS). "Second hits" such as infections, ischaemia/reperfusion or operations can further augment the pro-inflammatory immune response and have been correlated with the high morbidity and mortality in the latter times after trauma. SIRS can lead to tissue destruction in organs not originally affected by the initial trauma with subsequent development of multi-organ dysfunction (MOD). The initial pro-inflammatory response is followed by an anti-inflammatory response and can result in immune suppression with high risk of infection and sepsis. Trauma causes activation of nearly all components of the immune system. It activates the neuroendocrine system and local tissue destruction and accumulation of toxic byproducts of metabolic respiration leads to release of mediators. Extensive tissue injury may result in spillover of these mediators into the peripheral bloodstream to further maintain and augment the pro-inflammatory response. Hormones like ACTH, corticosteroids and catecholamines as well as cytokines, chemokines and alarmins play important roles in the initiation and persistence of the pro-inflammatory response after severe injury. The purpose of this review is therefore to describe the immunological events after trauma and to introduce important mediators and pathways of the inflammatory immune response.

    The aim was to use a novel functional luminal imaging probe for evaluation of wound defects and tissue damage resulting from the use of trocars. Following general anesthesia of 4 adult pigs, 6 different trocars were randomly inserted at preselected locations in the porcine abdominal wall. The functional luminal imaging probe was used to profile the trocar holes during bag distension from 8 axial cross-sectional area measurements. The cross-sectional areas and pressure in the bag were recorded and exported to Matlab for analysis and data display. Geometric profiles were generated, and the minimum cross-sectional area and hole length (abdominal wall thickness) were used as endpoints. Successful distensions were made in all cases. The slope of the contours increased away from the narrowest point of the hole. The slope increased more rapidly toward the inner abdominal wall than toward the outer wall. The slope of the linear trend lines for the cross-sectional area-pressure relation represents the compliance at the narrowest point in the wall. The hole length (abdominal wall thickness) could be obtained at different cross-sectional area cutoff points. A cutoff point of 300 mm(2) gave good results when compared to the length of the hole measured after the tissue was excised. This technique represents a new and straightforward way to evaluate the effects of trocars on the abdominal wall. It may also prove useful in comparing techniques and technology from different manufacturers. PMID:18757380

    This is a single center retrospective review of abdominal or abdomino-thoracic penetrating wounds treated between 2004 and 2013 in the gastrointestinal and emergency unit of the university hospital of Grenoble, France. This study did not include patients who sustained blunt trauma or non-traumatic wounds, as well as patients with penetrating head and neck injury, limb injury, ano-perineal injury, or isolated thoracic injury above the fifth costal interspace. In addition, we also included cases that were reviewed in emergency department morbidity and mortality conferences during the same period. Mortality was 5.9% (11/186 patients). Mean age was 36 years (range: 13-87). Seventy-eight percent (145 patients) suffered stab wounds. Most patients were hemodynamically stable or stabilized upon arrival at the hospital (163 patients: 87.6%). Six resuscitative thoracotomies were performed, five for gunshot wounds, one for a stab wound. When abdominal exploration was necessary, laparotomy was chosen most often (78/186: 41.9%), while laparoscopy was performed in 46 cases (24.7%), with conversion to laparotomy in nine cases. Abdominal penetration was found in 103 cases (55.4%) and thoracic penetration in 44 patients (23.7%). Twenty-nine patients (15.6%) had both thoracic and abdominal penetration (with 16 diaphragmatic wounds). Suicide attempts were recorded in 43 patients (23.1%), 31 (72.1%) with peritoneal penetration. Two patients (1.1%) required operation for delayed peritonitis, one who had had a laparotomy qualified as "negative", and another who had undergone surgical exploration of his wound under general anesthesia. In conclusion, management of clear-cut or suspected penetrating injury represents a medico-surgical challenge and requires effective management protocols. PMID:27318585

    Major injury is the sixth leading cause of death worldwide. Among those under 35 years of age, it is the leading cause of death and disability. Traffic accidents alone are the main cause, fundamentally in low- and middle-income countries. Patients over 65 years of age are an increasingly affected group. For similar levels of injury, these patients have twice the mortality rate of young individuals, due to the existence of important comorbidities and associated treatments, and are more likely to die of medical complications late during hospital admission. No worldwide, standardized definitions exist for documenting, reporting and comparing data on severely injured trauma patients. The most common trauma scores are the Abbreviated Injury Scale (AIS), the Injury Severity Score (ISS) and the Trauma and Injury severity Score (TRISS). Documenting the burden of injury also requires evaluation of the impact of post-trauma impairments, disabilities and handicaps. Trauma epidemiology helps define health service and research priorities, contributes to identify disadvantaged groups, and also facilitates the elaboration of comparable measures for outcome predictions.

  1. Male genital trauma

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references.

  2. Abdominal breathing manoeuvre reduces passive drag acting on gliding swimmers.

    The purpose of this study was to test the hypothesis that the passive drag acting on a gliding swimmer is reduced if the swimmer adopts an abdominal breathing manoeuvre (expanding the abdominal wall) rather than chest breathing manoeuvre (expanding the rib cage). Eleven male participants participated in this study. A specialised towing machine was used to tow each participant with tension set at various magnitudes and to record time series data of towing velocity. Participants were asked to inhale air by expanding the abdominal wall or the rib cage and to maintain the same body configuration throughout gliding. The steady-state velocity was measured and the coefficient of drag was calculated for each towing trial to compare between the breathing manoeuvres. The results showed that the towing velocity was increased by 0.02 m/s with a towing force of 34.3 N and by 0.06 m/s with a towing force of 98.1 N. The coefficient of drag was reduced by 5% with the abdominal breathing manoeuvre, which was found to be statistically significant (p < 0.05). These results indicate that adopting the abdominal breathing manoeuvre during gliding reduces the passive drag and the hypothesis was supported.

    Blunt abdominal aortic trauma is a rare occurrence in children with only a few patients having been reported in the literature. Most such cases have been described in the context of lap belt injuries. We report a 9-year-old boy who suffered lap belt trauma to the abdomen during a high-speed road traffic accident resulting to the well-recognized pattern of blunt abdominal injury, that is, the triad of intestinal perforation, fractures of the lumbar spine, and abdominal aortic injury. The latter presented with lower limb ischemia due to dissection of the infrarenal aorta and right common iliac artery. Revascularization was achieved by endovascular means using 2 self-expanding stents in the infrarenal aorta and the right common iliac artery. This case is one of the few reports of lap belt-related acute traumatic abdominal aortic dissection in a young child and highlights the feasibility of endovascular management in the pediatric population.

    Resuscitation of a severely traumatised patient with the administration of crystalloids, or colloids along with blood products is a common transfusion practice in trauma patients. The determination of this review article is to update on current transfusion practices in trauma. A search of PubMed, Google Scholar, and bibliographies of published studies were conducted using a combination of key-words. Recent articles addressing the transfusion practises in trauma from 2000 to 2014 were identified and reviewed. Trauma induced consumption and dilution of clotting factors, acidosis and hypothermia in a severely injured patient commonly causes trauma-induced coagulopathy. Early infusion of blood products and early control of bleeding decreases trauma-induced coagulopathy. Hypothermia and dilutional coagulopathy are associated with infusion of large volumes of crystalloids. Hence, the predominant focus is on damage control resuscitation, which is a combination of permissive hypotension, haemorrhage control and haemostatic resuscitation. Massive transfusion protocols improve survival in severely injured patients. Early recognition that the patient will need massive blood transfusion will limit the use of crystalloids. Initially during resuscitation, fresh frozen plasma, packed red blood cells (PRBCs) and platelets should be transfused in the ratio of 1:1:1 in severely injured patients. Fresh whole blood can be an alternative in patients who need a transfusion of 1:1:1 thawed plasma, PRBCs and platelets. Close monitoring of bleeding and point of care coagulation tests are employed, to allow goal-directed plasma, PRBCs and platelets transfusions, in order to decrease the risk of transfusion-related acute lung injury.

    The purpose of this article is to depict the spectrum of scrotal injuries in blunt trauma. Scrotal injuries are not very common and are mostly due to blunt trauma from direct injury, sports injuries or motor vehicle accidents. To minimize complications and ensure testicular salvage, rapid and accurate diagnosis is necessary. High-resolution USG is the investigation of choice, as it is readily available, accurate and has been seen to improve outcomes. An understanding of and familiarity with the sonographic appearance of scrotal injuries on the part of the radiologist/sonographer is therefore of key importance. PMID:23833421

    Many youth experience ongoing trauma exposure, such as domestic or community violence. Clinicians often ask whether evidence-based treatments containing exposure components to reduce learned fear responses to historical trauma are appropriate for these youth. Essentially the question is, if youth are desensitized to their trauma experiences, will this in some way impair their responding to current or ongoing trauma? The paper addresses practical strategies for implementing one evidence-based treatment, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with ongoing traumas. Collaboration with local therapists and families participating in TF-CBT community and international programs elucidated effective strategies for applying TF-CBT with these youth. These strategies included: 1) enhancing safety early in treatment; 2) effectively engaging parents who experience personal ongoing trauma; and 3) during the trauma narrative and processing component focusing on a) increasing parental awareness and acceptance of the extent of the youths’ ongoing trauma experiences; b) addressing youths’ maladaptive cognitions about ongoing traumas; and c) helping youth differentiate between real danger and generalized trauma reminders. Case examples illustrate how to use these strategies in diverse clinical situations. Through these strategies TF-CBT clinicians can effectively improve outcomes for youth experiencing ongoing traumas. PMID:21855140

    An infected aortic aneurysm, or mycotic aneurysm, is a rare arterial dilatation due to destruction of the infected vessel wall. Common pathogens resulting in an infected aortic aneurysm are Salmonella and Clostridium species, as well as Staphylococcus aureus; Morganella morganii, on the other hand, is very rare. An infected abdominal aortic aneurysm has tendencies to grow rapidly and to rupture. The mortality rate is high in patients undergoing emergent surgical intervention. We report the case of a 65-year-old man who presented with an infected abdominal aortic aneurysm caused by M. morganii. A high index of suspicion and imaging tests are necessary in order to diagnose an infected aortic aneurysm.

    Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal masses where two-thirds were of renal origin. Ultrasound diagnosis was correct in 68 patients (78%). All cases of hydronephrosis were correctly diagnosed based on characteristic ultrasound appearances. Correct diagnoses of all cases of adrenal hematoma, psoas abscess, liver hematoma, liver abscess and one case of liver metastases were achieved with correlation of relevant clinical information.

  13. Advances in prehospital trauma care

    2011-01-01

    Prehospital trauma care developed over the last decades parallel in many countries. Most of the prehospital emergency medical systems relied on input or experiences from military medicine and were often modeled after the existing military procedures. Some systems were initially developed with the trauma patient in mind, while other systems were tailored for medical, especially cardiovascular, emergencies. The key components to successful prehospital trauma care are the well-known ABCs of trauma care: Airway, Breathing, Circulation. Establishing and securing the airway, ventilation, fluid resuscitation, and in addition, the quick transport to the best-suited trauma center represent the pillars of trauma care in the field. While ABC in trauma care has neither been challenged nor changed, new techniques, tools and procedures have been developed to make it easier for the prehospital provider to achieve these goals in the prehospital setting and thus improve the outcome of trauma patients.

    Introduction Diaphragmatic rupture is an infrequent complication of trauma, occurring in about 5% of those who suffer a severe closed thoracoabdominal injury and about half of the cases are diagnosed early. High morbidity and mortality from bowel strangulation and other sequelae make prompt surgical intervention mandatory. Case presentation Four Brazilian men with a delayed diagnosis of a rare occurrence of traumatic diaphragmatic hernia. Patient one had diaphragmatic rupture on the right side of thorax and the others three patients on the left thoracic side, all they had to approach by a laparotomy and some approach in the chest, either thoracotomy or VATS. This injuries required surgical repositioning of extensively herniated abdominal viscera and intensive postoperative medical management with a careful control of intra-abdominal pressure. Discussion The negative pressure of the thoracic cavity causes a gradually migration of abdominal contents into the chest; this sequestration reduces the abdomen’s ability to maintain the viscera in their normal anatomical position. When the hernia is diagnosed early, the repair is less complicated and requires less invasive surgery. Years after the initial trauma, the diaphragmatic rupture produces dense adhesions between the chest and the abdominal contents. Conclusions All cases demonstrated that surgical difficulty increases when diaphragmatic rupture is not diagnosed early. It should be noted that when trauma to the thoraco-abdominal transition area is blunt or penetrating, a thorough evaluation is required to rule out diaphragmatic rupture and a regular follow-up to monitor late development of this comorbidity.

    A case of leaking mycotic abdominal aortic aneurysm is reported, with a brief review of the literature. A 58 year old female presented with shoulder and abdominal pain associated with diarrhoea, vomiting and fever with leucocytosis. Computed tomography of the abdomen showed pooling of contrast in the retroperitoneum anterior to a non-dilated abdominal aorta. There was considerable retroperitoneal blood accumulating in a mass-like lesion in the right lower abdomen and pelvis obstructing the right renal collecting system. Laparotomy revealed a 4 cm diameter saccular aneurysm of the abdominal aorta, with a 1 cm diameter neck. Culture of the thrombus grew Streptococcus pyogenes. PMID:7993259

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    Nonoperative management for traumatic injuries has significantly influenced trauma care during the last decade. We undertook this study to assess the impact of nontherapeutic laparotomies for suspected abdominal injuries compared with delayed laparotomies for questionable abdominal injuries for patients with abdominal trauma. The records of patients admitted to the trauma service between 2002 and 2007 who underwent laparotomies deemed nontherapeutic or delayed were retrospectively reviewed. Demographics, severity of injury, management scheme, and outcome data were analyzed. Sixteen patients underwent delayed laparotomies, whereas 26 patients incurred nontherapeutic laparotomies. Injury severity scores, Glasgow coma scale scores, abdominal abbreviated injury scale score (AIS), and age were similar for both populations. Delayed laparotomies occurred an average of 7 +/- 9 days postinjury. Intensive care unit length of stay (26 +/- 24 vs 10 +/- 6 days), hospital length of stay (40 +/- 37 vs 11 +/- 10 days), ventilator days (31 +/- 29 vs 11 +/- 10), and number of abdominal operative procedures (1.9 +/- 1.5 vs 1 +/- 0) were significantly higher in the delayed laparotomies group versus the nontherapeutic laparotomies group, respectively. Delayed diagnosis of intra-abdominal injuries yielded a significantly increased morbidity and mortality. During the evolving era of technological imaging for traumatic injuries, we must not allow the nonoperative pendulum to swing too far.

Of the patients, 77% underwent lateral venorrhaphy, 5% underwent infrarenal ligation of the inferior vena cava (IVC), and 18% died perioperatively before any caval repair could be carried out. There was an overall perioperative mortality of 39%. Persistent shock, the site of the venous injury, particularly in the retrohepatic position, and the number of associated vascular injuries were directly related to mortality. Irrespective of the improvements in resuscitation and the various operative methods available, penetrating trauma of the abdominal IVC remains a life-threatening injury. PMID:8943628

    Head injury commonly presents in association with torso or limb injuries, especially in blunt trauma mechanisms. Stopping life-threatening thoraco-abdominal hemorrhage and preventing secondary brain injury are time critical priorities. Although simultaneous operative management by multiple teams has been common practice in the recent wars in Iraq and Afghanistan, simultaneous surgery is rare in most civilian settings. Nevertheless, situations arise whereby simultaneous craniotomy and chest or abdominal surgery is necessary to prevent mortality or reduce severe morbidity. We discuss two recent cases at our level one trauma centre, the challenges that surgeons and the operating room staff face and propose that with appropriate planning this surgical capability can be integrated into the systems of contemporary advanced trauma units.

    Pediatric spinal trauma is unique. The developing pediatric spinal column and spinal cord deal with direct impact and indirect acceleration/deceleration or shear forces very different compared to adult patients. In addition children are exposed to different kind of traumas. Moreover, each age group has its unique patterns of injury. Familiarity with the normal developing spinal anatomy and kind of traumas is essential to correctly diagnose injury. Various imaging modalities can be used. Ultrasound is limited to the neonatal time period; plain radiography and computer tomography are typically used in the acute work-up and give highly detailed information about the osseous lesions. Magnetic resonance imaging is more sensitive for disco-ligamentous and spinal cord injuries. Depending on the clinical presentation and timing of trauma the various imaging modalities will be employed. In the current review article, a summary of the epidemiology and distribution of posttraumatic lesions is discussed in the context of the normal anatomical variations due to progressing development of the child.

    Orbital emphysema is typically a benign condition that occurs following forceful injection of air into the orbital soft tissue spaces. In many cases there is a history of trauma and fracture of an orbital bone, which permits air entry. However, other mechanisms of orbital emphysema have been reported including infection, pulmonary barotrauma, injury from compressed-air hoses, and complications from surgery including dental procedures. Here, we describe a report of a teenager who suffered an isolated medial orbital wall fracture while playing basketball, and several hours later developed orbital emphysema acutely after sneezing. We will review the radiological evaluation of orbital fractures and emphysema.

  7. [Abdominal cavity adhesions. Some issues of pathogenesis, prophylaxis and treatment].

    PubMed

    Tishchenko, V V

    2010-07-01

    The abdominal cavity adhesions (ACA) constitute frequent consequence of various abdominal cavity diseases and traumas and frequent cause of the abdominal adhesive disease and its complications. In spite of the known pathogenesis of ACA, the surgeons had failed throughout the decades of years to find out the measures and methods of its prophylaxis. There are several causes of such a situation and the main of them is that ACA in its origin constitutes a philogenetically developed defense biologic reaction of organism. Because of the fact, that an organism constitutes the self-regulated biological system, any external inputs (including the treatment), directed on qualitative or quantitative signs of these reactions, meet systemic counteraction and become annihilated. The forced overcome of such a counteraction may cause the development of severe systemic disorders in organism. The only prophylactic measures against ACA, which were already tested throughout the time, are the tactical and technical methods, promoting the reduction of severity of morphological changes in peritoneum and abdominal organs, thus causing reduction of natural reaction of organism. When the adhesions formation is inevitable it is necessary to apply surgical methods of governing such a process, and omentoparietopexy may constitutes one of such methods.

    Introduction Loss of intestinal integrity has been implicated as an important contributor to the development of excessive inflammation following severe trauma. Thus far, clinical data concerning the occurrence and significance of intestinal damage after trauma remain scarce. This study investigates whether early intestinal epithelial cell damage occurs in trauma patients and, if present, whether such cell injury is related to shock, injury severity and the subsequent inflammatory response. Methods Prospective observational cohort study in 96 adult trauma patients. Upon arrival at the emergency room (ER) plasma levels of intestinal fatty acid binding protein (i-FABP), a specific marker for damage of differentiated enterocytes, were measured. Factors that potentially influence the development of intestinal cell damage after trauma were determined, including the presence of shock and the extent of abdominal trauma and general injury severity. Furthermore, early plasma levels of i-FABP were related to inflammatory markers interleukin-6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP). Results Upon arrival at the ER, plasma i-FABP levels were increased compared with healthy volunteers, especially in the presence of shock (P < 0.01). The elevation of i-FABP was related to the extent of abdominal trauma as well as general injury severity (P < 0.05). Circulatory i-FABP concentrations at ER correlated positively with IL-6 and PCT levels at the first day (r2 = 0.19; P < 0.01 and r2 = 0.36; P < 0.001 respectively) and CRP concentrations at the second day after trauma (r2 = 0.25; P < 0.01). Conclusions This study reveals early presence of intestinal epithelial cell damage in trauma patients. The extent of intestinal damage is associated with the presence of shock and injury severity. Early intestinal damage precedes and is related to the subsequent developing inflammatory response. PMID:19505335

    The liver is the most commonly injured intra-abdominal organ. Liver mass is the key factor in determining the extent of the inertial force and consequently of damage in the case of sudden deceleration. In this respect, high-speed accidents usually produce characteristic lesions where the III-IV segments tear at the level of the hepatic ligament causing grade I-III liver injuries. The pathophysiology of such traumas is the subject of the present contribution. All trauma patients who sustained a blunt abdominal injury from January 1 to December 31 2004 were identified by the trauma registry at the Policlinico di Tor Vergata In order to select high-speed and sudden deceleration traumas, clinical records were reviewed for demographics, severity of injury, severity of liver injury, associated concomitant injuries, and management scheme. The grade of liver injury was determined on the basis of the initial CT or the intraoperative findings. A total of 159 patients who incurred abdominal injuries due to blunt trauma were identified. In 14 (8.8 percent) one or more liver lesions were associated. Among the low-grade injuries, 3 were grade I, and 8 grade II. Forty percent were high-grade injuries consisting in 6 grade III and 1 grade IV. We observed no grade V or grade VI injuries in this series. The most frequent occurrence was a tear between hepatic segments III and IV caused by the acute impact of the liver on the hepatic ligament. A hepatic injury caused by the round ligament was diagnosed intraoperatively in 1 out of 5 liver trauma patients (20 percent) and preoperatively in 4 out of 5 (80 percent) in our one-year abdominal blunt trauma series. Our clinical contribution underlines the high frequency of such lesions that seems to be related to, and characteristic of, high-speed trauma. In these cases immediate deceleration due to the impact may be a relevant factor in the pathophysiology of the lesion.

    Abdominal closure is a complex surgical problem in intestinal transplant recipients with loss of abdominal domain, as graft exposure results in profound morbidity. Although intraoperative coverage techniques have been described, this is the first report of preoperative abdominal wall augmentation using tissue expanders in patients awaiting intestinal transplantation. We report on five patients who received a total of twelve tissue expanders as a means to increase abdominal surface area. Each patient had a compromised abdominal wall (multiple prior operations, enterocutaneous fistulae, subcutaneous abscesses, stomas) with loss of domain and was identified as high risk for an open abdomen post-transplant. Cross-sectional imaging and dimensional analysis were performed to quantify the effect of the expanders on total abdominal and intraperitoneal cavity volumes. The overall mean increase in total abdominal volume was 958 cm(3) with a mean expander volume of 896.5 cc. Two expanders were removed in the first patient due to infection, but after protocol modification, there were no further infections. Three patients eventually underwent small bowel transplantation with complete graft coverage. In our preliminary experience, abdominal tissue expander placement is a safe, feasible, and well-tolerated method to increase subcutaneous domain and facilitate graft coverage in patients undergoing intestinal transplantation.

    According to the National Trauma Institute (2015), trauma accounts for more than 180,000 deaths each year in the United States. Nurses play a significant role in the care of trauma patients and therefore need appropriate education and training (L. ). Although several courses exist for trauma education, many nurses have not received adequate education in trauma management (B. ; L. ). Trauma Tactics, a 2-day course that focuses on high-fidelity human patient simulation, was created to meet this educational need. This descriptive study was conducted retrospectively to assess the effectiveness of the Trauma Tactics course. Pre- and postsurveys, tests, and simulation performance were used to evaluate professional nurses who participated in Trauma Tactics over a 10-month period. Fifty-five nurses were included in the study. Pre- and postsurveys revealed an increase in overall confidence, test scores increased by an average of 2.5 points, and simulation performance scores increased by an average of 16 points. Trauma Tactics is a high-quality course that provides a valuable and impactful educational experience for nurses. Further research is needed to evaluate the long-term effects of Trauma Tactics and its impacts on quality of care and patient outcomes. PMID:27414143

    Objectives: To investigate the effect of non-elastic/elastic abdominal binders on intra-vesical pressure (IVP), physiological functions, and clinical outcomes in laparotomy patients at the perioperative stage. Methods: This prospective study was conducted from May to October 2014 at the Trauma Surgery Department, Daping Hospital, Chongqing, China. Laparotomy patients were randomly divided into non-elastic abdominal binder group (28 patients), and elastic abdominal binder group (29 patients). Binders were applied for 14 days following the operation, or until discharge. Demographic information, Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores (prior to the operation, on the first day after operation, the day IVP measurement was stopped, and one day before discharge), and outcomes were recorded. The IVP was measured before the operation to postoperative day 7. Results: There were no significant differences in the demographic information, outcomes, SOFA or APACHE-II scores between the 2 groups. Initial out-of-bed mobilization occurred earlier in the elastic binder group (3.2 ± 2.0 versus 5.0 ± 3.7 days, p=0.028). A greater increase in IVP was observed in the non-elastic binder group than in the elastic binder group (2.9 ± 1.1 versus 1.1 ± 0.7 mm Hg, p=0.000). Conclusion: Elastic binders have relatively little effect on IVP and are more helpful at promoting postoperative recovery than non-elastic binders. Therefore, elastic binders are more suitable for clinical use. PMID:26739977

    Objective: To describe outcomes from a clinical trauma surgical education program that places the board-eligible/board-certified fellow in the role of the attending surgeon (fellow-in-exception [FIE]) during the latter half of a 2-year trauma/surgical critical care fellowship. Summary Background Data: National discussions have begun to explore the question of optimal methods for postresidency training in surgery. Few objective studies are available to evaluate current training models. Methods: We analyzed provider-specific data from both our trauma registry and performance improvement (PI) databases. In addition, we performed TRISS analysis when all data were available. Registry and PI data were analyzed as 2 groups (faculty trauma surgeons and FIEs) to determine experience, safety, and trends in errors. We also surveyed graduate fellows using a questionnaire that evaluated perceptions of training and experience on a 6-point Likert scale. Results: During a 4-year period 7,769 trauma patients were evaluated, of which 46.3% met criteria to be submitted to the PA Trauma Outcome Study (PTOS, ie, more severe injury). The faculty group saw 5,885 patients (2,720 PTOS); the FIE group saw 1,884 patients (879 PTOS). The groups were similar in respect to mechanism of injury (74% blunt; 26% penetrating both groups) and injury severity (mean ISS faculty 10.0; FIEs 9.5). When indexed to patient contacts, FIEs did more operations than the faculty group (28.4% versus 25.6%; P < 0.05). Death rates were similar between groups (faculty 10.5%; FIEs 10.0%). Analysis of deaths using PI and TRISS data failed to demonstrate differences between the groups. Analysis of provider-specific errors demonstrated a slightly higher rate for FIEs when compared with faculty when indexed to PTOS cases (4.1% versus 2.1%; P < 0.01). For both groups, errors in management were more common than errors in technique. Twenty-one (91%) of twenty-three surveys were returned. Fellows’ feelings of preparedness

    Immunonutrition may be superior to standard clinical nutrition in specific clinical situations. After severe trauma, an enteral immuno-enhancing diet, enriched with arginine, omega-3 fatty acids, and nucleotides, decreases infectious complications. During acute respiratory distress syndrome, a continuous enteral diet with high-dose omega-3 fatty acids, gamma-linolenic acid, and antioxidants improved clinical outcome. Glutamine should be administered enterally or parenterally whenever total parenteral nutrition is indicated.

    Recent years have seen the rise of historical trauma as a construct to describe the impact of colonization, cultural suppression, and historical oppression of Indigenous peoples in North America (e.g., Native Americans in the United States, Aboriginal peoples in Canada). The discourses of psychiatry and psychology contribute to the conflation of disparate forms of violence by emphasizing presumptively universal aspects of trauma response. Many proponents of this construct have made explicit analogies to the Holocaust as a way to understand the transgenerational effects of genocide. However, the social, cultural, and psychological contexts of the Holocaust and of post-colonial Indigenous "survivance" differ in many striking ways. Indeed, the comparison suggests that the persistent suffering of Indigenous peoples in the Americas reflects not so much past trauma as ongoing structural violence. The comparative study of genocide and other forms of massive, organized violence can do much to illuminate both common mechanisms and distinctive features, and trace the looping effects from political processes to individual experience and back again. The ethics and pragmatics of individual and collective healing, restitution, resilience, and recovery can be understood in terms of the self-vindicating loops between politics, structural violence, public discourse, and embodied experience.

    Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to frank osteo-ligamentous instability with spinal cord injury. The emergent evaluation of patients at risk relies on standardized clinical and radiographic protocols to identify injuries; elucidate associated pathology; classify injuries; and predict instability, treatment and outcomes. The unique anatomy of each region of the cervical spine demands a review of each segment individually. This article examines both upper cervical spine injuries, as well as subaxial spine trauma. The purpose of this article is to provide a review of the broad topic of cervical spine trauma with reference to the classic literature, as well as to summarize all recently available literature on each topic. Identification of References for Inclusion: A Pubmed and Ovid search was performed for each topic in the review to identify recently published articles relevant to the review. In addition prior reviews and classic references were evaluated individually for inclusion of classic papers, classifications and previously unidentified references. PMID:21139776

    External laryngeal trauma is a rare but potentially life-threatening situation in the acutely injured patient. Trauma mechanism and magnitude, maximum focus of the applied force, and patient related factors, such as age and ossification of the laryngeal cartilages influence the spectrum of observed injuries. Their correct diagnosis and prompt management are paramount in order to avoid patient death or long-term impairment of breathing, swallowing and speaking. The current review provides a comprehensive approach to the radiologic interpretation of imaging studies performed in patients with suspected laryngeal injury. It describes the key anatomic structures that are relevant in laryngeal trauma and discusses the clinical role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the acute emergency situation. The added value of two-dimensional multiplanar reconstructions (2D MPR), three-dimensional volume rendering (3D VR) and virtual endoscopy (VE) for the non-invasive evaluation of laryngeal injuries and for treatment planning is discussed. The clinical presentation, biomechanics of injury, diagnostic pitfalls and pearls, common and uncommon findings are reviewed with emphasis of fracture patterns, involvement of laryngeal joints, intra- and extralaryngeal soft tissue injuries, and complications seen in the acute emergency situation. The radiologic appearance of common and less common long-term sequelae, as well as treatment options are equally addressed.

    We discuss the results of combined in-vitro laboratory measurements and clinical observations aimed at determining the effect that the unsteady wall shear stresses and the pressure may have on the growth and eventual rupturing of an Abdominal Aortic Aneurysm (AAA), a permanent bulging-like dilatation occurring near the aortic bifurcation. In recent years, new non-invasive techniques, such as stenting, have been used to treat these AAAs. However, the development of these implants, aimed at stopping the growth of the aneurysm, has been hampered by the lack of understanding of the effect that the hemodynamic forces have on the growth mechanism. Since current in-vivo measuring techniques lack the precision and the necessary resolution, we have performed measurements of the pressure and shear stresses in laboratory models. The models of the AAA were obtained from high resolution three-dimensional CAT/SCANS performed in patients at early stages of the disease. Preliminary DPIV measurements show that the pulsatile blood flow discharging into the cavity of the aneurysm leads to large spikes of pressure and wall shear stresses near and around its distal end, indicating a possible correlation between the regions of high wall shear stresses and the observed location of the growth of the aneurysm.

    Trauma remains the leading cause of death under the age of 35 years. England and Wales lost 252,000 working years from accidental deaths, including poison, in 1992. In this country, preventable deaths from trauma are inappropriately high. In many hospitals there are not enough personnel; in the majority, there are no recognisable trauma care systems, which can reduce preventable deaths to a minimum. The appropriateness of trauma centres for this country is being assessed in Stoke-on-Trent, and a report is due out later this year. Even if the recommendation is made to establish such centres, it is unlikely that many will be set up. Consequently most hospitals will have to rely on their own resources to set up and run a trauma team. This type of trauma care system is the subject of this article. PMID:8977939

    It is well known that so-called bullet-proof vests offer protection against a wide range of penetrating trauma, but their protection against blunt trauma is less well understood. Fast projectiles may result in hematomas and contusions behind the armour. We report a traffic accident involving a young soldier wearing a ballistic protection vest resulting in a right thoracoabdominal blunt trauma leading to a confined liver compression rupture. As nearly no skin marks were detectable, we point out that every emergency department surgeon should be very suspicious if a patient wore a ballistic vest at the time of the accident--there may be no skin marks despite severe intra-abdominal trauma. Our patient recovered following hypotensive ICU treatment, thrombocyte mobilization, and factor VIIa substitution. PMID:18854963

    Solitary fibrous tumor (SFT) of the peritoneum is an unusual spindle-cell neoplasm. SFT was originally described in the pleura; however it is now diagnosed in multiple extrathoracic sites. Most believe that the tumor is of mesenchymal origin and should be classified as a variant of fibroma. SFT of the pleura and peritoneum have also been called fibrous mesothelioma, and the cell of origin is felt to be a pluripotential submesothelial mesenchymal cell. Primary tumors arising in hernia sacs are rare, and we report on two patients with hernia SFT. The first is a 67-year-old man who had a diffusely thickened distal left inguinal hernia sac. Within the sac was copious myxoid material mimicking pseudomyxoma peritonei. Herniorrhaphy and orchiectomy were performed. The second is a 44-year-old woman with a midepigastric mass attached to a ventral hernia. Wide local excision was performed. Both tumors demonstrated plump spindle cells, one with myxoid background and the other with keloidal collagen. Calretinin immunostaining was positive in both tumors, whereas CD34 was negative. This suggests tumor origin from a submesothial pluripotential cell that maintains potential for mesothelial differentiation. Surgical excision is the treatment of choice with the degree of resectability being a powerful predictor of outcome.

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery.

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

    Remnant malignant tissue is left behind after conventional surgery for an unresectable intraperitoneal malignant tumor. Standard radiotherapy or chemotherapy rarely enables good tumor control. We report the case of a 74-year-old man who developed a local recurrence of a sigmoid tumor located 5 to 6 cm from the anus. The tumor was fixed to the pelvic wall and could not be totally eradicated with conventional surgery. Preoperative peroperative assessment confirmed the absence of metastatic spread. Radiotherapy could not be performed due to risk of bowel injury. Peroperative radiofrequency ablation was followed by surgical colorectal resection without restoration of intestinal continuity, leaving only tumor tissue destroyed by radiofrequency. No adjuvant treatment was proposed because of intolerance to chemotherapy. Clinical assessment and thoracic and abdominal CT scan confirmed the absence of recurrence 26 months after radiofrequency ablation. Serum markers remained normal.

    We have previously reported that abdominal irradiation prior to i.v. injection of syngeneic tumor cells reduced metastases in lung. Our report described an investigation of the significance of intestinal organisms in the radiation effect. We found that eliminating intestinal organisms with antibiotics totally abolished the radiation effect. Monoassociation of germ-free mice revealed that the radiation effect was observable only for Enterobacter cloacae, never for Streptococcus faecium, Bifidobacterium adlesentis, or Escherichia coli. After abdominal irradiation of regular mice, E. cloacae multiplied in cecal contents, adhered to mucous membranes, invaded the cecal wall, and translocated to mesenteric lymph nodes. Intravenous administration of E. cloacae in place of abdominal irradiation inhibited metastases. E. cloacae-monoassociated mice developed fewer metastases than germ-free mice, and the reduction was further enhanced by abdominal irradiation. We concluded that abdominal irradiation caused the invasion of E. cloacae from the mucous membrane of the intestine and inhibited formation of lung metastases.

    The authors analyzed the single-center experience of treatment of 72 patients with abdominal aortic aneurisms and severe accompanied pathology. The aneurisms were repaired by stent-grafts. All the patients had abdominal aortic aneurisms with the diameters from 41 to 84 mm against the background of severe somatic pathology. It was a contraindication to planned open surgery. An installation of stent-graft was successful in all 72 follow-ups. It wasn't necessary to use a conversion to open surgery. The follow-up period consisted of 44,6?2,1 months. Control ultrasound and computer tomography studies hadn't revealed an increase of aneurism sack sizes or "eakages". A reduction of abdominal aortic aneurism sizes was noted in 37 patients on 4-5% during first year after operation. The stent-graft implantation extends the possibilities of abdominal aortic aneurism treatment for patients from a high surgical risk group. PMID:26234059

    Dextromethorphan is an N-methyl-D-aspartate (NMDA) receptor antagonist which has been shown to inhibit the development of cutaneous secondary hyperalgesia after tissue trauma. We studied 60 ASA I-II patients undergoing total abdominal hysterectomy in a randomized, double-blind, placebo-controlled study. Patients received either dextromethorphan 27 mg capsules, two doses before operation and three doses in the first 24 h after operation, or placebo. Visual analogue pain scores (VAS) at 24 and 48 h were assessed at rest, on coughing and on sitting up, and were not significantly different between groups. Morphine consumption from a patient-controlled analgesia (PCA) device was also not significantly different between groups. Evidence of secondary hyperalgesia was assessed with von Frey hairs 10 cm above the Pfannenstiel incision. Both groups of patients exhibited evidence of secondary hyperalgesia after 24 and 48 h but there were no significant differences between groups. There was also no difference between groups in VAS scores at 1 month.

    AIM: To investigate the features of abdominal crush injuries resulting from an earthquake using multidetector computed tomography (MDCT). METHODS: Fifty-one survivors with abdominal crush injuries due to the 2008 Sichuan earthquake underwent emergency non-enhanced scans with 16-row MDCT. Data were reviewed focusing on anatomic regions including lumbar vertebrae, abdominal wall soft tissue, retroperitoneum and intraperitoneal space; and types of traumatic lesions. RESULTS: Fractures of lumbar vertebrae and abdominal wall soft tissue injuries were more common than retro- and intraperitoneal injuries (P < 0.05). With regard to the 49 lumbar vertebral fractures in 24 patients, these occurred predominantly in the transverse process (P < 0.05), and 66.67% of patients (16/24) had fractures of multiple vertebrae, predominantly two vertebrae in 62.5% of patients (10/16), mainly in L1-3 vertebrae in 81.63% of the vertebrae (40/49). Retroperitoneal injuries occurred more frequently than intraperitoneal injuries (P < 0.05), and renal and liver injuries were most often seen in the retroperitoneum and in the intraperitoneal space, respectively (all P < 0.05). CONCLUSION: Transverse process fractures in two vertebrae among L1-3 vertebrae, injury of abdominal wall soft tissue, and renal injury might be features of earthquake-related crush abdominal injury.

    Divergent phenotypes between the perivascular adipose tissue (PVAT) surrounding the abdominal and the thoracic aorta might be implicated in regional aortic differences, such as susceptibility to atherosclerosis. Although PVAT of the thoracic aorta exhibits anti-contractile function, the role of PVAT in the regulation of the vascular tone of the abdominal aorta is not well defined. In the present study, we compared the anti-contractile function, nitric oxide (NO) availability, and reactive oxygen species (ROS) formation in PVAT and vessel walls of abdominal and thoracic aorta. Abdominal and thoracic aortic tissue from male Wistar rats were used to perform functional and molecular experiments. PVAT reduced the contraction evoked by phenylephrine in the absence and presence of endothelium in the thoracic aorta, whereas this anti-contractile effect was not observed in the abdominal aorta. Abdominal PVAT exhibited a reduction in endothelial NO synthase (eNOS) expression compared with thoracic PVAT, without differences in eNOS expression in the vessel walls. In agreement with this result, NO production evaluated in situ using 4,5-diaminofluorescein was less pronounced in abdominal compared with thoracic aortic PVAT, whereas no significant difference was observed for endothelial NO production. Moreover, NOS inhibition with L-NAME enhanced the phenylephrine-induced contraction in endothelial-denuded rings with PVAT from thoracic but not abdominal aorta. ROS formation and lipid peroxidation products evaluated through the quantification of hydroethidine fluorescence and 4-hydroxynonenal adducts, respectively, were similar between PVAT and vessel walls from the abdominal and thoracic aorta. Extracellular superoxide dismutase (SOD) expression was similar between the vessel walls and PVAT of the abdominal and thoracic aorta. However, Mn-SOD levels were reduced, while CuZn-SOD levels were increased in abdominal PVAT compared with thoracic aortic PVAT. In conclusion, our results

    Abdominal enterocele is a result of entering abdominal organs into peritoneal pockets and folds through the holes in mesenterium or into the adjoining cavities through defects in their walls. Enteroceles are localized at the sites where one segment of the gastrointestinal tract passes into another, in a pocket behind the cecum and sigmoid, between mesenteric layers of small intestine and colon, in the holes of mesenterium of vermiform appendage, gastrocolic and falciform ligaments, pockets and holes of broad ligament of the uterine, omental foramen, rectouterine excavation, and diaphragmal defects. We observed a 26 year old woman with enterocele entrapment in the abdominal cavity complicated by necrosis of part of the small intestine.

    Major trunk trauma is common and costly, but comparisons of costs between trauma centers (TCs) are rare. Understanding cost is essential to improve quality, manage trauma service lines, and to facilitate institutional commitment for trauma. We have used results of a statewide trauma financial survey of Levels I to IV TC to develop a useful grouping method for costs and clinical characteristics of major trunk trauma. The trauma financial survey collected billing and clinical data on 75 per cent of the state trauma registry patients for fiscal year 2012. Cost was calculated by separately accounting for embedded costs of trauma response and verification, and then adjusting reasonable costs from the Medicare cost report for each TC. The cost-to-charge ratios were then recalculated and used to determine uniform cost estimates for each patient. From the 13,215 patients submitted for the survey, we selected 1,094 patients with major trunk trauma: lengths of stay ≥ 48 hours and a maximum injury of AIS ≥3 for either thorax or abdominal trauma. These patients were then divided into three Injury Severity Score (ISS) groups of 9 to 15, 16 to 24, or 25+ to stratify patients into similar injury groups for analysis of cost and cost drivers. For abdominal injury, average total cost for patients with ISS 9 to 15 was $17,429. Total cost and cost per day increased with severity of injury, with $51,585 being the total cost for those with ISS 25. Similar trends existed for thoracic injury. Use of the Medicare cost report and cost-to-charge ratios to compute uniform costs with an innovative grouping method applied to data collected across a statewide trauma system provides unique information regarding cost and outcomes, which affects quality improvement, trauma service line management, and decisions on TC participation.

    In the 20th century, the complications of head injuries were controlled but not eliminated. The wars of the 21st century turned attention to blast, the instant of impact and the primary injury of concussion. Computer calculations have established that in the first 5 milliseconds after the impact, four independent injuries on the brain are inflicted: 1) impact and its shockwave, 2) deceleration, 3) rotation and 4) skull deformity with vibration (or resonance). The recovery, pathology and symptoms after acute brain trauma have always been something of a puzzle. The variability of these four modes of injury, along with a variable reserve of neurones, explains some of this problem.

Therapists often request strategies for using evidence-based treatments (EBTs) for this population. This article describes practical strategies for applying Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with complex trauma. Methods TF-CBT treatment phases are described and modifications of timing, proportionality and application are described for youth with complex trauma. Practical applications include a) dedicating proportionally more of the model to the TF-CBT coping skills phase; b) implementing the TF-CBT Safety component early and often as needed throughout treatment; c) titrating gradual exposure more slowly as needed by individual youth; d) incorporating unifying trauma themes throughout treatment; and e) when indicated, extending the TF-CBT treatment consolidation and closure phase to include traumatic grief components and to generalize ongoing safety and trust. Results Recent data from youth with complex trauma support the use of the above TF-CBT strategies to successfully treat these youth. Conclusions The above practical strategies can be incorporated into TF-CBT to effectively treat youth with complex trauma. Practice implications Practical strategies include providing a longer coping skills phase which incorporates safety and appropriate gradual exposure; including relevant unifying themes; and allowing for an adequate treatment closure phase to enhance ongoing trust and safety. Through these strategies therapists can successfully apply TF-CBT for youth with complex trauma. PMID:22749612

  12. Management of Colorectal Trauma

    2011-01-01

    Although the treatment strategy for colorectal trauma has advanced during the last part of the twentieth century and the result has improved, compared to other injuries, problems, such as high septic complication rates and mortality rates, still exist, so standard management for colorectal trauma is still a controversial issue. For that reason, we designed this article to address current recommendations for management of colorectal injuries based on a review of literature. According to the reviewed data, although sufficient evidence exists for primary repair being the treatment of choice in most cases of nondestructive colon injuries, many surgeons are still concerned about anastomotic leakage or failure, and prefer to perform a diverting colostomy. Recently, some reports have shown that primary repair or resection and anastomosis, is better than a diverting colostomy even in cases of destructive colon injuries, but it has not fully established as the standard treatment. The same guideline as that for colonic injury is applied in cases of intraperitoneal rectal injuries, and, diversion, primary repair, and presacral drainage are regarded as the standards for the management of extraperitoneal rectal injuries. However, some reports state that primary repair without a diverting colostomy has benefit in the treatment of extraperitoneal rectal injury, and presacral drainage is still controversial. In conclusion, ideally an individual management strategy would be developed for each patient suffering from colorectal injury. To do this, an evidence-based treatment plan should be carefully developed. PMID:21980586

  13. Haemodynamic changes in trauma.

    PubMed

    Kirkman, E; Watts, S

    Trauma is the leading cause of death during the first four decades of life in the developed countries. Its haemodynamic response underpins the patient's initial ability to survive, and the response to treatment and subsequent morbidity and resolution. Trauma causes a number of insults including haemorrhage, tissue injury (nociception) and, predominantly, in military casualties, blast from explosions. This article discusses aspects of the haemodynamic responses to these insults and subsequent treatment. 'Simple' haemorrhage (blood loss without significant volume of tissue damage) causes a biphasic response: mean arterial blood pressure (MBP) is initially maintained by the baroreflex (tachycardia and increased vascular resistance, Phase 1), followed by a sudden decrease in MAP initiated by a second reflex (decrease in vascular resistance and bradycardia, Phase 2). Phase 2 may be protective. The response to tissue injury attenuates Phase 2 and may cause a deleterious haemodynamic redistribution that compromises blood flow to some vital organs. In contrast, thoracic blast exposure augments Phase 2 of the response to haemorrhage. However, hypoxaemia from lung injury limits the effectiveness of hypotensive resuscitation by augmenting the attendant shock state. An alternative strategy ('hybrid resuscitation') whereby tissue perfusion is increased after the first hour of hypotensive resuscitation by adopting a revised normotensive target may ameliorate these problems. Finally, morphine also attenuates Phase 2 of the response to haemorrhage in some, but not all, species and this is associated with poor outcome. The impact on human patients is currently unknown and is the subject of a current physiological investigation.

    In most cases, gas in the abdominal cavity indicates perforation of the gastrointestinal wall. We describe a patient, in whom the cause of abdominal gas detected in computed tomography turned out to be emphysematous cholecystitis caused by gas-producing bacteria. It is a rare disease characterized by accumulation of gas into the gall bladder or its wall. The gas can be easily observed in computed tomography. The disease easily becomes complicated and is associated with high mortality. Prompt cholecystectomy and antibiotic therapy are the cornerstones of the treatment.

    Although toxicology screening is often used when treating trauma patients, its utility and significance remain controversial. Data from 623 toxicology screens performed in urban trauma center patients with mental status alterations are reported. The study patients were predominantly black and male, with a mean age of 32 (+/- 22) years. Overall, 86% of screens were positive. Substances of abuse, including ethanol, were noted in 525 (84%) of urine toxicology screens. Ethanol, cannabinoids, and cocaine were the drugs most commonly found in urine, with positivity noted in 53%, 37%, and 34% of screens. Serum analysis was 44% positive, with ethanol noted in 41% of patients. In blacks, the odds ratio of illicit drug use before trauma ranged from 1.9 to 4.2 (p less than 0.005), and in those aged 17 to 40 years, the odds ratio for illicit urine drugs ranged from 4.7 to 16.8 (p less than 0.001). In patients older than 40 years, the odds of a positive serum ethanol level were 1.7 times greater than in younger patients, and a level above 300 mg% was 3.8 times more likely in this age group (p less than 0.001). When serum ethanol was detected, the odds ratio of a head injury was 1.4 relative to patients without serum ethanol (p less than 0.06), and the odds ratio for abdominal injury was 1.6 for patients with serum ethanol (p less than 0.03). The odds of a TS less than 12 were 1.8 (p less than 0.05), and the odds of a GCS less than 12 were 3.3 (p less than 0.001) with ethanol levels greater than 100 mg%.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2593195

    Prehospital emergency care in Singapore has taken shape over almost a century. What began as a hospital-based ambulance service intended to ferry medical cases was later complemented by an ambulance service under the Singapore Fire Brigade to transport trauma cases. The two ambulance services would later combine and come under the Singapore Civil Defence Force. The development of prehospital care systems in island city-state Singapore faces unique challenges as a result of its land area and population density. This article defines aspects of prehospital trauma care in Singapore. It outlines key historical milestones and current initiatives in service, training, and research. It makes propositions for the future direction of trauma care in Singapore. The progress Singapore has made given her circumstances may serve as lessons for the future development of prehospital trauma systems in similar environments.

    Maternal mortality is an important indicator of adequacy of health care in our society. Improvements in the obstetric care system as well as advances in technology have contributed to reduction in maternal mortality rates. Trauma complicates up to 7% of all pregnancies and has emerged as the leading cause of maternal mortality, becoming a significant concern for the public health system. Maternal mortality secondary to trauma can often be prevented by coordinated medical care, but it is essential that caregivers recognize the unique situation of providing simultaneous care to 2 patients who have a complex physiologic relationship. Optimal management of the pregnant trauma victim requires a multidisciplinary team, where the obstetrician plays a central role. This review focuses on the incidence of maternal mortality due to trauma, the mechanisms involved in traumatic injury, the important anatomic and physiologic changes that may predispose to mortality due to trauma, and finally, preventive strategies that may decrease the incidence of traumatic maternal death.

    INTRODUCTION Internal abdominal hernias are infrequent but an increasing cause of bowel obstruction still often underdiagnosed. Among adults its usual causes are congenital anomalies of intestinal rotation, postsurgical iatrogenic, trauma or infection diseases. PRESENTATION OF CASE We report the case of a 63-year-old woman with history of chronic constipation. The patient was hospitalized for two days with acute abdominal pain, abdominal distension and inability to eliminate flatus. The X-ray and abdominal computerized tomography scan (CT scan) showed signs of intestinal obstruction. Exploratory laparotomy performed revealed a trans-mesenteric hernia containing part of the transverse colon. The intestine was viable and resection was not necessary. Only the hernia was repaired. DISCUSSION Internal trans-mesenteric hernia constitutes a rare type of internal abdominal hernia, corresponding from 0.2 to 0.9% of bowel obstructions. This type carries a high risk of strangulation and even small hernias can be fatal. This complication is specially related to trans-mesenteric hernias as it tends to volvulize. Unfortunately, the clinical diagnosis is rather difficult. CONCLUSION Trans-mesenteric internal abdominal hernia may be asymptomatic for many years because of its nonspecific symptoms. The role of imaging test is relevant but still does not avoid the necessity of exploratory surgery when clinical features are uncertain. PMID:24880799

    Abdominal compartment syndrome is a surgical emergency caused by a raised intra-abdominal pressure, which may lead to respiratory, cardiovascular and renal compromise. It is most commonly seen in post-operative and trauma patients and it has a variety of causes. Tension pneumoperitoneum (TP) is a rare cause of abdominal compartment syndrome most often seen after gastrointestinal endoscopy with perforation. We present the case of a fit 52-year-old experienced female diver who developed TP and shock following a routine training dive to 27m. Following accidental inhalation of water, she had an unstaged ascent and, on reaching the surface, developed severe acute abdominal pain and distension. She was brought to our emergency department by air ambulance for assessment. Clinical and radiological examination revealed a shocked patient with dramatic free intra-abdominal gas and signs of abdominal compartment syndrome, which was treated with needle decompression. Symptoms and signs resolved quickly with no need for further surgical intervention. TP is a surgical emergency where surgery can be avoided with prompt diagnosis and treatment.

    This case report concerns a 62-year-old woman with spontaneous infrarenal abdominal aortic dissection, which developed into claudication and rest pain in the lower extremity. Multi-row detector computed tomography showed the entry site of the abdominal aortic dissection at the second lumbar artery, while the reentry site was found intraoperatively at the median sacral artery, indicating that the false lumen had progressed and compressed the true lumen. A direct approach involving grafting appears to be an effective procedure for resolving mesenteric and lower extremity hypoperfusion due to aortic dissection with a dilated false channel, even during the acute period.

Optimal treatment of these injuries is frequently hampered by considerable delays in diagnosis. Factors contributing to these delays include the location of much of the duodenum and the pancreas in the retroperitoneum resulting in an absence of initial symptoms and signs, the often trivial nature of some of the responsible blunt traumatic accidents, inappropriate child-parent or child-physician communication, failure to achieve a meaningful physical examination in uncooperative or unconscious patients, and false negative paracentesis. Eighty per cent of these injuries occurred in boys. Eleven of 16 patients with pancreatic trauma had pseudocysts. A persistently elevated serum amylase level was invariably noted and epigastric mass was palpable in eight patients. Significant delays in diagnosis were prevalent and pseudocysts was misdiagnosed as appendicitis in three cases. Internal drainage by cystgastrostomy or cystjejunostomy was effective operative treatment. In instances of acute pancreatic injuries, sump drains, gastrostomy, cholecystostomy, and total parenteral hyperalimentation were useful therapeutic adjuncts. There was one death for a 6.2 per cent mortality rate. Forty patients had gastrointestinal injuries involving the duodenum in 17, jejunum in 14, ileum in seven, and stomach in two. Perforations occured in 65 per cent of cases, obstructing hematomas in 30 per cent, and mesenteric avulsions in 5 per cent. Associated injuries were observed in 15 patients (37.5 per cent). Pain and tenderness were the only consistent findings. Upper gastrointestinal contrast studies were diagnostic of duodenal hematomas. Eighty per cent of perforations were managed by simple closures and 20 per cent by resection and anastomosis. Obstructing hematomas unassociated with other injuries may be expected to

    Blunt abdominal trauma with major vascular involvement is found to be rare. Although few series have been reported in the literature, the true incidence of blunt abdominal aortic injury is unknown. Different modalities of blunt trauma may occur among civilians with steering wheel and seat belt injury secondary to motor vehicle accident the most frequent. Mechanical forces produce variable patterns of injury; therefore, the onset of signs and symptoms can be different. Dissection and thrombosis of the abdominal aorta have been frequently described among seat-belted adult patients with major vascular involvement. The associated abdominal viscus and/or vertebral lesions must always be taken into account. Prompt diagnosis allows adequate surgical treatment. We present the case of a 66-year-old woman, restrained front passenger involved in a motor vehicle collision, who had small bowel transection, vertebral fractures, and aortic partial occlusion below inferior mesenteric artery with bilateral iliac artery involvement. Along with the case reported, the purpose of this study is to highlight and compare features and management of the previous cases described in the English literature.

  9. Skiing and spinal trauma.

    Spinal injury in skiers can either be acute or chronic. Acute spinal injury accounts for 3 to 3.6 per cent of all injuries occurring in Alpine skiing. Fewer acute injuries occur in cross-country skiing, and those that do usually are the result of a sudden, compressive force from a seated fall. The prevalence of chronic spinal trauma in skiing is unknown. Both cross-country and Alpine skiers appear to have greater complaints of mild to moderate low back pain as compared with their nonskiing counterparts. These differences may be the result of a complex interaction between recreational and occupational activities. Theoretical analyses suggest a risk for low-grade torsional injury to the Alpine skier's spine, whereas in cross-country skiing significant shear forces are applied to lumbar discs during the kick but not the double-poling phase.

    Victims of traumatic events who experience re-traumatization often develop a highly ambivalent relationship to God and all religiosity as extremely conflictual. On the one hand, they may choose to blame God for not having protected them, for having left them to feel so alone, for having been indifferent to them or they may even turn their wrath upon God, as the source of cruelty. Often though, the traumas experienced by individuals prompt them to turn to God and religion in search of help. This gives reason for the need of new and up-to-date research that can help elucidate why some people choose to seek help in religion and others turn away from it.

    Abstract Kaposiform hemangioendothelioma (KH) is a rare vascular tumor of intermediate malignancy that occurs mainly in the childhood. Adult patients with KH are rare. Imaging findings of KH have rarely been reported before. We present magnetic resonance imaging (MRI), computed tomography (CT), and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT findings in an adult patient with KH associated with lymphangiomatosis involving mesentery and ileum. A 22-year-old female complained of a 9-month history of intermittent melena, weakness, and palpitation. Laboratory tests revealed anemia and hypoproteinemia. Fecal occult blood test was positive. Abdominal enhanced MRI and CT showed a large abdominal mass involving mesentery and ileum. On enhanced MRI, there were many hypervascular nodules in the mass. On FDG PET/CT, the mass and the nodules showed slight FDG uptake. Small bowel capsule endoscopy showed numerous grape-shaped red nodules in the luminal wall of the involved ileum. The patient underwent resection of the abdominal mass and a segment of the ileum invaded by the abdominal mass. KH arising within lymphangiomatosis involving mesentery and ileum was confirmed by pathology. After surgery, the patient's symptoms improved. This is the first case of KH associated with lymphangiomatosis involving mesentery and ileum. In this case, the lymphangiomatosis overshadowed the small tumor nodules resulting in unusual imaging findings. Familiarity with these imaging findings is helpful for diagnosis and differential diagnosis of KH. PMID:26871848

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa.

    Liposuction is a well-established procedure that is generally safe. However, rare complications can occur. The authors report on a 38-year-old woman who underwent combined abdominoplasty and liposuction at a private clinic. Four hours after the procedure, severe hypovolemic shock developed and required emergency transfer to a tertiary-care center. After primary fluid resuscitation, abdominal ultrasonography and computerized tomography revealed severe right-sided liver trauma, with active bleeding and free intra-abdominal fluid. Two attempts at right hepatic artery embolization failed to fully control the bleeding, and surgical hemostasis was required. After a 2-week hospitalization, the patient was discharged, and she returned to work 3 months later. Although it appears that this is the first reported case of liver trauma during liposuction, this potential complication should be kept in mind and identified early to permit efficient and effective management.

    The use of CT in the diagnosis and management of liver trauma is responsible for the shift from routine surgical versus non-surgical treatment in the management of traumatic liver injuries, even when they are of high grade. The main cause of complication and of death in liver trauma is related to vascular injury. The goal of this review focussed on the vascular complications of liver trauma is to describe the elementary lesions shown by CT in liver trauma including laceration, parenchymal hematoma and contusions, partial devascularisation, subcapsular hematomas, hemoperitoneum, active bleeding, pseudoaneurysm of the hepatic artery, bile leak, and periportal oedema, to illustrate the possible pitfalls in CT diagnosis of liver trauma and to underline the key-points which may absolutely be present in a CT report of liver trauma. Then we will remind the grading system based on the CT features and we will analyze the interest and limitations of such grading systems. Last we will discuss the diagnostic strategy at the early phase in patients with suspected liver trauma according to their clinical conditions and underline the conditions of arterial embolization, and then we will discuss the diagnosis strategy at the delayed phase according to the suspected complications.

    Background and Objectives Findings on disclosure and adjustment following traumatic events have been mixed. Better understanding of individual differences in disclosure may help us better understand reactions following trauma exposure. In particular, studying disclosure patterns for those with and without psychopathology and for different types of emotional experiences may help clarify the relationship between disclosure, event emotionality, trauma exposure, and PTSD. Methods In this study, 143 men and women with (n = 67) and without (n = 43) chronic PTSD and without trauma exposure (n = 33) provided information on disclosure for a traumatic/severe life event, a negative event, and a positive event. Results Individuals with PTSD reported greater difficulty disclosing their traumatic event compared to those with trauma exposure no PTSD and those with no-trauma exposure. However, individuals with PTSD reported disclosing the traumatic event a similar number of times and with similar levels of detail to those with trauma exposure but no PTSD. Both sexual and childhood trauma were associated with greater disclosure difficulty. Limitations Although control event types (positive, negative) were selected to control for the passage of time and for general disclosure style, they do not control for salience of the event and results may be limited by control events that were not highly salient. Conclusions The present findings point to a dynamic conceptualization of disclosure, suggesting that the differential difficulty of disclosing traumatic events seen in individuals with PTSD is not simply a function of the amount of disclosure or the amount of details provided.

    Recurrent abdominal pain is a common presenting complaint among children. A thorough history and physical examination and limited laboratory investigation should enable a physician to make a positive diagnosis of "functional" recurrent abdominal pain in 90% to 95% of cases; an organic cause is identified in only 5% to 10%. The care and thoroughness of the history and physical examination establish the physician's credibility; explaining the clinical basis for the diagnosis and educating the child and parents on what is known about the condition reassures the parents.

    Abdominal bloating is a very common and troublesome symptom of all ages, but it has not been fully understood to date. Bloating is usually associated with functional gastrointestinal disorders or organic diseases, but it may also appear alone. The pathophysiology of bloating remains ambiguous, although some evidences support the potential mechanisms, including gut hypersensitivity, impaired gas handling, altered gut microbiota, and abnormal abdominal-phrenic reflexes. Owing to the insufficient understanding of these mechanisms, the available therapeutic options are limited. However, medical treatment with some prokinetics, rifaximin, lubiprostone and linaclotide could be considered in the treatment of bloating. In addition, dietary intervention is important in relieving symptom in patients with bloating. PMID:24199004

Postoperative and spontaneous abscesses did equally well. Most intra-abdominal and retroperitoneal abscesses are amenable to this form of percutaneous drainage. The procedure requires only local anaesthesia and is well tolerated. Surgical management should probably now be reserved for those cases which are considered unsuitable for percutaneous drainage or which fail to resolve following this procedure. PMID:6842496

    Millions of children are affected by physical and sexual abuse, natural and technological disasters, transportation accidents, invasive medical procedures, exposure to community violence, violence in the home, assault, and terrorism. Unfortunately, the emotional impact of exposure to trauma on children is often unappreciated and therefore untreated, and yet the impact of exposures to disaster and violence is profound and long-lasting. This article first briefly discusses the epidemiology of trauma in children, and then reviews the psychiatric and neurodevelopmental impact of trauma on children as well as the effects of trauma on children's emotional development. Trauma in children can lead to the development of posttraumatic stress disorder as well as to a variety of other psychiatric disorders, including depression, generalized anxiety disorder, panic attacks, borderline personality disorder, and substance abuse in adult survivors of trauma. Research has found that early exposure to stress and trauma causes physical effects on neurodevelopment which may lead to changes in the individual's long-term response to stress and vulnerability to psychiatric disorders. Exposure to trauma also affects children's ability to regulate, identify, and express emotions, and may have a negative effect on the individual's core identity and ability to relate to others. The authors also discuss what has been learned, based on recent experiences such as the World Trade Center catastrophe, about the role of television viewing in increasing the effects of traumatic events. The last section of the article provides guidance concerning the identification and clinical treatment of children and adolescents who are having emotional problems as a result of exposure to trauma.

    The principles of a standard abdominal reduction are well understood; this technique has been used for many years. However, a reverse abdominal reduction may be considered in some cases, for example, continued weight loss, and thus skin redundancy on the upper abdomen in patients who have already undergone abdominal reduction and upper abdomen improvement in patients requiring a mastopexy or breast reduction simultaneously. Reverse abdominal reduction is rarely mentioned in the medical literature, but it can prove successful; although the scar across the lower sternum has often been considered to be unsatisfactory, often it does not prove to be so. Thus, this procedure can be proven to be successful in suitable cases. Secondly, the Pfannenstiel incision, if not satisfactorily repaired in the first instance, can become fixated to the abdominal wall; this fixation along with the inevitable migration of skin and fat at its cephalic edge causes a rather displeasing contour defect when wearing tight-fitting swimwear. The principle of the waistcoating procedure is essentially to chamfer the fat cephalically; this procedure is employed for removing the Pfannenstiel scar from the abdominal wall. The principle is simple and effective and can be applied in cases with fixated scars. These two aforementioned principles are not commonly used, but they can prove particularly effective in suitable cases. We illustrate the principles. PMID:26966077

  4. Ultrasound Screening for Abdominal Aortic Aneurysm

    PubMed Central

    2006-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness of ultrasound screening for asymptomatic abdominal aortic aneurysm (AAA). Clinical Need Abdominal aortic aneurysm is a localized abnormal dilatation of the aorta greater than 3 cm. In community surveys, the prevalence of AAA is reported to be between 2% and 5.4%. Abdominal aortic aneurysms are found in 4% to 8% of older men and in 0.5% to 1.5% of women aged 65 years and older. Abdominal aortic aneurysms are largely asymptomatic. If left untreated, the continuing extension and thinning of the vessel wall may eventually result in rupture of the AAA. Often rupture may occur without warning, causing acute pain. Rupture is always life threatening and requires emergency surgical repair of the ruptured aorta. The risk of death from ruptured AAA is 80% to 90%. Over one-half of all deaths attributed to a ruptured aneurysm take place before the patient reaches hospital. In comparison, the rate of death in people undergoing elective surgery is 5% to 7%; however, symptoms of AAA rarely occur before rupture. Given that ultrasound can reliably visualize the aorta in 99% of the population, and its sensitivity and specificity for diagnosing AAA approaches 100%, screening for aneurysms is worth considering as it may reduce the incidence of ruptured aneurysms and hence reduce unnecessary deaths caused by AAA-attributable mortality. Review Strategy The Medical Advisory Secretariat used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases to determine the effectiveness of ultrasound screening for abdominal aortic aneurysms. Case reports, letters, editorials, nonsystematic reviews, non-human studies, and comments were excluded. Questions asked: Is population-based AAA screening effective in improving health outcomes in asymptomatic populations? Is AAA screening acceptable to the population? Does this affect the

    Ultrasound is of prO)len accuracy in abdominal and thoracic trauma and may be useful to diagnose extremity injury in situations where radiography is not available such as military and space applications. We prospectively evaluated the utility of extremity , ultrasound performed by trained, non-physician personnel in patients with extremity trauma, to simulate remote aerospace or military applications . Methods: Patients with extremity trauma were identified by history, physical examination, and radiographic studies. Ultrasound examination was performed bilaterally by nonphysician personnel with a portable ultrasound device using a 10-5 MHz linear probe, Images were video-recorded for later analysis against radiography by Fisher's exact test. The average time of examination was 4 minutes. Ultrasound accurately diagnosed extremity, injury in 94% of patients with no false positive exams; accuracy was greater in mid-shaft locations and least in the metacarpa/metatarsals. Soft tissue/tendon injury was readily visualized . Extremity ultrasound can be performed quickly and accurately by nonphysician personnel with excellent accuracy. Blinded verification of the utility of ultrasound in patients with extremity injury should be done to determine if Extremity and Respiratory evaluation should be added to the FAST examination (the FASTER exam) and verify the technique in remote locations such as military and aerospace applications.

    Despite their frequent appearance, intra-abdominal adhesions are rarely the subject of clinical studies and academic discussions. For many years the operators have been trying to reduce such unfavourable consequences of interventions in the abdominal structures. The aim of this article is to present the possibilities of intra-abdominal adhesion diagnostics by means of ultrasound imaging based on authors' own experience and information included in pertinent literature. The anatomy and examination technique of the abdominal wall were discussed in Part I of the article. In order to evaluate intraperitoneal adhesions, one should use a convex transducer with the frequency of 3.5-6 MHz. The article provides numerous examples of US images presenting intra-abdominal adhesions, particularly those which appeared after surgical procedures. The significance of determining their localisation and extensiveness prior to a planned surgical treatment is emphasized. Four types of morphological changes in the ultrasound caused by intra-abdominal adhesions are distinguished and described: visceroperitoneal adhesions, intraperitoneal adhesions, adhesive obstructions as well as adhesions between the liver and abdominal wall with a special form of such changes, i.e. hepatic pseudotumour. Its ultrasound features are as follows:The lesion is localised below the scar in the abdominal wall after their incision.The lesion is localised in the abdominal part of the liver segments III, IV and V.With the US beam focus precisely set, the lack of fascia - peritoneum complex may be noticed. An uneven liver outline or its ventral displacement appears.A hepatic adhesion-related pseudotumour usually has indistinct margins, especially the posterior one, and, gradually, from top to bottom, loses its hypoechogenic nature.In a respiration test, this liver fragment does not present the sliding movement - a neoplastic tumour rarely shows such an effect.

    It needs to be emphasized that ultrasonography is a primary test performed in order to evaluate the abdominal wall and structures located in their vicinity. It allows for the determination of the anatomy and lesions in this localization. Thorough knowledge concerning the ultrasound anatomy of the tested structures constitutes a basis of all diagnostic successes. Therefore, this part of the article is devoted to this subject matter. The possibility to diagnose intra-abdominal adhesions with ultrasound is underestimated and rarely used. The aim of this paper is to discuss and document the ultrasound anatomy of the posterior surface of the abdominal wall as well as to present techniques directed at the detection of adhesions, in particular the visceroperitoneal ones. The posterior surface of the abdominal wall constitutes an extensive tissue area of complex structure, with folds and ligaments surrounded by various amounts of the epiperitoneal fat. In some places, this tissue separates the components of the fascia and peritoneum complex. The ultrasound manifestation of this complex is two hyperechogenic lines placed parallelly to each other in the places where they are not separated by the accumulated adipose tissue. Another factor which separates the peritoneum from the viscera is of dynamic character. It is a so-called visceral slide induced by easy or deep breathing. Its size should not be lower than 1 cm and the deflections gradually and symmetrically diminish from the epigastric to hypogastric region. Last but not least, the evaluation of the reciprocal relation of the abdominal wall with viscera may be aided by rhythmical manual compressions on the abdominal wall (ballottement sign) performed below the applied ultrasound transducer. During this test, the size of the visceral slide in relation to the abdominal wall is observed. The maneuver is usually performed in uncooperative patients or those with shallow breath. The authors' own experiences indicate that the

    The only criteria currently used to inform surgical decision for abdominal aortic aneurysms are maximum diameter (>5.5 cm) and rate of growth, even though several studies have identified the need for more specific indicators of risk. Patient-specific biomechanical variables likely to affect rupture risk would be a valuable addition to the science of understanding rupture risk and prove to be a life saving benefit for patients. Local deformability of the aorta is related to the local mechanical properties of the wall and may provide indication on the state of weakening of the wall tissue. We propose a 3D image-based approach to compute aortic wall strain maps in vivo. The method is applicable to a variety of imaging modalities that provide sequential images at different phases in the cardiac cycle. We applied the method to a series of abdominal aneurysms imaged using cine-MRI obtaining strain maps at different phases in the cardiac cycle. These maps could be used to evaluate the distensibility of an aneurysm at baseline and at different follow-up times and provide an additional index to clinicians to facilitate decisions on the best course of action for a specific patient.

    We developed and evaluated a surgical procedure for implanting intra-abdominal radiotransmitters with external whip antennas in captive mallards (Anas platyrhynchos). Transmitters were implanted in the abdominal cavity and the antennas exited through the caudal abdominal wall and skin. Birds with implanted transmitters developed mild to moderate localized air sac reactions. These reactions involved adhesions of the right anterior abdominal air sac to the liver with contractions around the transmitters and antenna catheters. The adhesions were reinforced by a proliferation of connective tissue and lined by multinucleated giant cells (foreign body reaction). Casual observation indicated that neither behavior nor activity of the birds was altered by the histological reaction to the transmitter implant. No increase in systemic lesions (particularly liver or kidney) could be correlated with the histological reactions. Our evaluations indicate that the procedure is a reliable method for radiomarking ducks and the technique has been successfully used in 2 field studies.

    Aneurysm is defined as a localized and permanent dilatation with an increase in normal diameter by more than 50%. It is more common in males and can affect up to 8% of elderly men. Smoking is the greatest risk factor for abdominal aortic aneurysm (AAA) and other risk factors include hypertension, hyperlipidemia, family history of aneurysms, inflammatory vasculitis, and trauma. Endovascular Aneurysm Repair [EVAR] is a common procedure performed for AAA, because of its minimal invasiveness as compared with open surgical repair. Patients undergoing EVAR have a greater incidence of major co-morbidities and should undergo comprehensive preoperative assessment and optimization within the multidisciplinary settings. In majority of cases, EVAR is extremely well-tolerated. The aim of this article is to outline the Anesthetic considerations related to EVAR. PMID:26750684

    Introduction. Incisional hernias are a common complication appearing after abdominal wall defects reconstruction, with omphalocele and gastroschisis being the most common etiologies in children. Abdominal closure of these defects represents a real challenge for pediatric surgeons with many surgical techniques and various prosthetic materials being used for this purpose. Case Report. We present a case of repair of a postoperative ventral hernia occurring after congenital omphalocele reconstruction in a three-and-a-half-year-old child using an acellular, sterile, porcine dermal mesh. Conclusion. Non-cross-linked acellular porcine dermal matrix is an appropriate mesh used for the reconstruction of abdominal wall defects and their postoperative complications like large ventral hernias with success and preventing their recurrence.

    This is a retrospective study of 500 patients with spinal cord injury who underwent abdominal ultrasonography as a routine screening test from 2000 to 2003. We analyzed the results according to the different abdominal organ systems. Among the 500 cases, 226 (45.2%) showed abnormal findings. 98 cases of abnormal findings in the liver included 75 of fatty liver and 13 of mass. The 88 cases of abnormal findings in the bladder included 56 of bladder wall thickening, 14 of cystitis and 10 of urinary stone. The 35 cases of abnormal findings in the kidney included 19 of renal cyst and 6 of pelvic dilatation. The 35 cases with gallbladder abnormalities included 19 with gallstones and 11 with biliary sludge. Excluding the cases with bladder wall thickening, there were still 170 cases with abnormal ultrasonographic findings. Abdominal sonography seems to be a useful tool in detecting hidden intraabdominal pathologies in patients with spinal cord injury.

    Vascular trauma is associated with major morbidity and mortality, but little is known about its incidence or nature in Britain. A retrospective study of 36 patients requiring operative intervention for vascular trauma under one vascular surgeon over a 6-year period was undertaken. Twenty-four patients suffered iatrogenic trauma (median age 61 years); including cardiological intervention (19), radiological intervention (2), varicose vein surgery (1), umbilical vein catherisation (1) and isolated hyperthermic limb perfusion (1). There were 23 arterial and three venous injuries. Twelve patients had accidental trauma (median age 23 years). Three of the ten patients with blunt trauma were referred for vascular assessment before orthopaedic intervention, two after an on-table angiogram and five only after an initial orthopaedic procedure (range of delay 6 h to 10 days). Injuries were arterial in nine, venous in two and combined in one. Angiography was obtained in six patients, and in two patients with multiple upper limb fractures identified the site of injury when clinical localisation was difficult. A variety of vascular techniques were used to treat the injuries. Two patients died postoperatively and one underwent major limb amputation. Thirty-two (89%) remain free of vascular sequelae after a median follow-up of 48 months (range 3-72 months). Vascular trauma is uncommon in the United Kingdom. To repair the injuries a limited repertoire of vascular surgery techniques is needed. Therefore, vascular surgical assessment should be sought at an early stage to prevent major limb loss.

    Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair. PMID:26770280

    Background The use of alloplastic meshes has been historically contra-indicated in patients with infection. Aim To evaluate the use of polypropylene meshes in the treatment of abdominal wall defects in rats with peritonitis. Methods Twenty Wistar female rats were divided into two groups: induction of peritonitis (test group) and without peritonitis (control group). An abdominal wall defect was created in all animals, and polypropylene mesh was applied. The evaluation of the tensile strength of the mesh was carried out using tensiometer and microscopic analysis of the healing area was done. Results More adhesion of the mesh to the rat abdominal wall was observed in test group. The histopathological analyses showed prevalence of moderate to accentuated granulation tissue in both groups, without significant differences. Conclusion The use of the mesh coverage on abdominal wall defects of rats with induced peritonitis did not show worse results than its use in healthy animals, nor was its integration to the resident tissue any worse.

    Introduction: Heterotopic mesenteric ossification is an extremely rare condition, which often follows trauma and is frequently symptomatic. To date, there are no reports in the literature of abdominal compartment syndrome occurring after surgical resection of mesenteric calcification. The present report documents an unusual case of compartment syndrome complicating resection of extensive mesenteric calcification despite abdominal closure with the components-separation technique. Method: A 48-year-old man undergoing components-separation technique for posttraumatic laparostomy hernia repair (ileostomy reversal and sigmoid stricture correction) was found to have extensive heterotopic mesenteric calcification, which needed resection. Results: Resection of the mesenteric calcification was complicated by intraoperative hemorrhage and unplanned small bowel resection. Later the patient developed secondary hemorrhage leading to an abdominal compartment syndrome, which was successfully treated by decompression, hemostasis, and Permacol-assisted laparotomy wound closure. The patient remains symptom-free more than 2 years after surgery. Discussion: The case herein reported gives an account of the rare occurrence of abdominal compartment syndrome following resection of posttraumatic ectopic mesenteric ossifications. It is highly unusual in that it occurred because of “secondary hemorrhage” and despite abdominal closure with the components-separation technique, which had been undertaken precisely to prevent compartment syndrome with direct closure. It therefore highlights the need for continued clinical vigilance in complex posttraumatic cases. PMID:23573333

    Appraisals are a key feature in understanding an individual's experience; this is especially important when the experience is a traumatic one. However, research is diminutive when looking at the interaction between trauma appraisals and culture in relation to posttraumatic stress disorder using qualitative methodologies. This study explored cultural differences in perceptions and appraisals of trauma using three qualitative focus groups with community members (n = 11) from collectivistic cultures who had experienced a traumatic event and three qualitative individual key informant interviews with mental health practitioners (n = 3) routinely working with trauma survivors. Using template analysis, eight emergent themes were highlighted from the data sets [(1) trauma and adjustment; (2) cultural and social roles; (3) traumatised self; (4) relationships; (5) external attribution; (6) future; (7) education; (8) language] that potentially have significant consequences for posttrauma psychological adjustment and recovery. Cumulatively, while a number of themes are similar to that which is emphasised in current literature (e.g. damaged self, negative appraisals of the world, others, future) a number of themes were also resonant and warrant further scrutiny. For instance, the importance and interconnectedness of the group to the individual and the impact trauma has on this; the importance of social roles, cultural appropriateness and violations of cultural values and norms; findings and implications are discussed.

  8. Behind armour blunt trauma--an emerging problem.

    PubMed

    Cannon, L

    2001-02-01

    Behind Armour Blunt Trauma (BABT) is the non-penetrating injury resulting from the rapid deformation of armours covering the body. The deformation of the surface of an armour in contact with the body wall arises from the impact of a bullet or other projectile on its front face. The deformation is part of the retardation and energy absorbing process that captures the projectile. In extreme circumstances, the BABT may result in death, even though the projectile has not perforated the armour. An escalation of the available energy of bullets and the desire of armour designers to minimise the weight and bulk of personal armour systems will increase the risk of BABT in military and security forces personnel. In order to develop materials that can be interposed between the armour and the body wall to attenuate the transfer of energy into the body, it is essential that the mechanism of BABT is known. There is a great deal of activity within UK and NATO to unravel the interactions; the mechanism is likely to be a combination of stress (pressure) waves generated by the rapid initial motion of the rear of the armour, and shear deformation to viscera produced by gross deflection of the body wall. Physical and computer model systems are under development to characterise the biophysical processes and provide performance targets for materials to be placed between armours and the body wall in order to attenuate the injuries (trauma attenuating backings-TABs). The patho-physiological consequences of BABT are being clarified by research, but the injuries will have some of the features of blunt chest trauma observed in road traffic accidents and other forms of civilian blunt impact injury. The injuries also have characteristics of primary blast injury. An overview diagnosis and treatment is described. PMID:11307682

    Objectives To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. Design A retrospective review. Setting A regional trauma unit in a tertiary-care institution. Patients Multiply injured trauma patients admitted between January 1988 and December 1990 who died within 24 hours of injury and in whom an autopsy was done. Intervention Standard radiography of the chest. Main Outcome Measures Chest injuries diagnosed and recorded by the trauma room team from standard anteroposterior x-ray films compared with the findings at autopsy and with review of the films by a staff radiologist initially having no knowledge of the injuries and later, if injuries remained undetected, having knowledge of the autopsy findings. Results Thirty-seven patients met the study criteria, and their cases were reviewed. In 11 cases, significant injuries were noted at autopsy and not by the trauma-room team, and in 7 cases these injuries were also missed by the reviewing radiologist. Injuries missed by the team were: multiple rib fractures (11 cases), sternal fractures (3 cases), diaphragmatic tear (2 cases) and intimal aortic tear (1 case). In five cases, chest tubes were not inserted despite the presence (undiagnosed) of multiple rib fractures and need for intubation and positive-pressure ventilation. Conclusions Significant blunt abdominal trauma, potentially requiring operative management or chest-tube insertion, may be missed on the initial anteroposterior chest x-ray film. Caution must therefore be exercised in interpreting these films in the trauma resuscitation room. PMID:8599789

    Introduction The management of colon injuries has distinctly evolved over the last three decades. However, trauma surgeons often find themselves in a dilemma, whether to perform a diversion or to perform a primary repair. The purpose of this study is to evaluate risk factors in colon injury management and their influence on abdominal complications. Patients and methods This is a prospective study conducted at a national level I trauma center in Tirana, Albania from January 2009 to December 2012. The data with respect to demographics, physiological risk factors, intraoperative findings, and surgical procedures were collected. Colonic injury-related morbidity and mortality were analyzed. Multivariate logistic regression analysis was performed by assessing the influence of risk factors on abdominal complications. Results Of the 157 patients treated with colon injury, was performed a primary repair in 107 (68.15%) of the patients and a diversion in the remaining 50 (31.85%). The mean PATI was 18.6, while 37 (23.6%) of patients had PATI greater than 25. The complications and their frequencies according to the surgical technique used (primay repair vs diversion respectively) includes: wound infections (9.3% vs 50%), anastomotic leak (1.8% vs 8.7%), and intra-abdominal abscess (1.8% vs 6.5%). The multivariate analysis identified two independent risk factors for abdominal complications: transfusions of 4 units of blood within the first 24 hours (OR = 1.2 95% CI (1.03 –1.57) p =0.02), and diversion (OR = 9.6, 95% CI 4.4 – 21.3, p<0.001). Conclusion Blood transfusions of more than 4 units within the first 24 hours and diversion during the management of destructive colon injuries are both independent risk factors for abdominal complications. The socioeconomic impact and the need for a subsequent operation in colostomy patients are strong reasons to consider primary repair in the management of colon injuries. PMID:26017103

    We present the case of a 43-year-old gentleman who presented to the emergency room with acute abdominal distension, confusion and vascular collapse. The emergent radiologic imaging obtained showed massive bilateral adrenal enlargement, but despite the initial clinical suspicion of possible overwhelming sepsis and/or massive abdominal/intralesional hemorrhage, lab tests based obtained rapidly confirmed the diagnosis of acute Addisonian crisis which responded dramatically to adrenocorticoid hormone replacement therapy and aggressive fluid resuscitation. The patient's established history of metastatic lung cancer confirmed this as a case of metastatic massive bilateral adrenal metastases with an initial presentation of acute adrenal insufficiency which is uncommon in the setting of metastatic carcinomatosis but more typically associated with lymphomas. Recognition of this clinical possibility is vital to enable rapid diagnosis and consequent life saving therapy. PMID:27328473

    First cause of secondary hypertension is renovascular hypertension which presents abdominal bruit in 16 to 20% of cases. This clinical sign is also associated with other vascular disease of the abdomen such as celiac trunk stenosis and/or aneurysms located on the pancreaticoduodenal or gastroduodenal arcs level, with little representation among aneurysm. They usually appear on a context of digestive complications like neoplasias, chronic pancreatitis or gastric obstructions possibly with obstructive icterus, hemorrhage and acute abdomen episodes. Its presentation in other contexts is rare and constitutes a diagnostic challenge. Diagnosis is made by abdominal arteriography which is the best method because you can locate the problem as well as intervene therapeutically with embolization of the aneurysme. We would like to emphasize the importance of a quick diagnosis due to the risk of rupture and the high morbi-mortality associated.

    We report the case of a 39 year-old woman with many years of intermittent abdominal pain who was found to have cystic masses evocative of cystic lymphangioma involving the posterior mediastinal and retroperitoneum. Worsening abdominal pain led to a recommendation for laparoscopic unroofing and decompression of the cysts. During the postoperative period, hemorrhagic shock required reintervention with excision of the tumoral mass. Pathologic examination revealed lymphangioleiomyomatosis (LAM). On the 15th postoperative day, the patient developed a chylopneumothorax which required prolonged chest tube drainage. The presence of multiple polycystic lesions in the pulmonary parenchyma supported the diagnosis of diffuse LAM with primary extrapulmonary presentation. This diagnosis should be considered preoperatively since it modifies the treatment: a complete excision of the cystic lesions seems to be necessary in order to prevent bleeding and lymphatic extravasation.

    The attractive wall covering shown below is one of 132 styles in the Mirror Magic II line offered by The General Tire & Rubber Company, Akron, Ohio. The material is metallized plastic fabric, a spinoff from space programs. Wall coverings are one of many consumer applications of aluminized plastic film technology developed for NASA by a firm later bought by King-Seeley Thermos Company, Winchester, Massachusetts, which now produces the material. The original NASA use was in the Echo 1 passive communications satellite, a "space baloon" made of aluminized mylar; the high reflectivity of the metallized coating enabled relay of communications signals from one Earth station to another by "bouncing" them off the satellite. The reflectivity feature also made the material an extremely efficient insulator and it was subsequently widely used in the Apollo program for such purposes as temperature control of spacecraft components and insulation of tanks for fuels that must be maintained at very low temperatures. I Used as a wall covering, the aluminized material offers extra insulation, reflects light and I resists cracking. In addition to General Tire, King-Seeley also supplies wall covering material to Columbus Coated Fabrics Division of Borden, Incorporated, Columbus, Ohio, among others.

  18. Acute Abdominal Pain in Children.

    PubMed

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

A soft slowly growing resistance was present on the dorso-lateral side of the left chest wall, in the range of the seventh to ninth rib. According to the medical history, the patient did not have any prior trauma and malignancy. A well-defined tumor of the left chest wall with calcifications, which grew to the seventh and eighth intercostal space, was present on computed tomography (CT) and magnetic resonance (MR) scans. The patient underwent resection of the tumor with the chest wall and reconstruction with polypropylene mesh. Histologically, it was a venous hemangioma, one of very rare tumors of the chest wall.

    Lung injury in trauma patients can occur because of direct injury to lung or due to secondary effects of injury elsewhere for example fat embolism from a long bone fracture, or due to response to a systemic insult such as; acute respiratory distress syndrome (ARDS) secondary to sepsis or transfusion related lung injury. There are certain special situations like head injury where the primary culprit is not the lung, but the brain and the ventilator strategy is aimed at preserving the brain tissue and the respiratory system takes a second place. The present article aims to delineate the strategies addressing practical problems and challenges faced by intensivists dealing with trauma patients with or without healthy lungs. The lung protective strategies along with newer trends in ventilation are discussed. Ventilatory management for specific organ system trauma are highlighted and their physiological base is presented.
