Clarification of the role of CT scan in the acute evaluation of blunt abdominal trauma.

We reviewed 100 patients sustaining blunt trauma whose initial evaluation included an abdominal computed tomographic scan (CT) to assess the role of this modality in managing these patients. Indications for CT scan were suspicion of abdominal injury based on mechanism of injury (46), tenderness (22), falling hematocrit (9), hematuria (5), pain (4), and hyperamylasemia (1). Thirty-four patients had abdominal injury, and four scans identified non-traumatic pathology; 66 patients had no evidence of abdominal injury. There were no additional abdominal injuries detected during the hospitalizations. Mechanism of injury was the only indication for CT scan in 20 patients, none of whom had evidence of abdominal injury. CT scan charges for these 20 patients accounted for 5.5% of the total hospital bill ($204,070). Hospital costs would have been reduced by $11,270 if these patients had been followed clinically. Fifteen patients with soft tissue contusions and normal CT scans were hospitalized less than 72 hours. Room and other hospital charges accounted for 38.5% of the hospital bill; these are costs that would have been saved if these patients had been discharged from the emergency service. Several conclusions can be made from this study. First, abdominal CT scan is a sensitive test for abdominal injury. Secondly, patients without objective signs of abdominal injury whose other injuries warrant admission allowing further observation should be followed clinically and do not need the additional expense of abdominal CT scan. Finally, mechanism of injury alone is not an indication for CT scan.

Laparoscopic injury of abdominal wall blood vessels: a report of three cases.

BACKGROUND: Operative laparoscopy is being used for an increasing number of applications. Many of these innovative techniques require the insertion of large trocars through the anterior abdominal wall at points lateral to the midline. Because of the rich vascular supply of the anterior abdominal wall, the incidence of abdominal wall vessel injuries appears to be increased by these techniques. CASES: Three cases are reported in which abdominal wall blood vessels were injured during operative laparoscopy. Case 1 describes laceration of the inferior epigastric artery above the pubic crest. Despite initial hemostasis with a transabdominal suture ligation, postoperative blood loss necessitated transfusion and reoperation to control bleeding. Case 2 describes hematoma formation after unrecognized injury to one of the epigastric vessels. The hematoma resolved without sequelae with conservative treatment. Case 3 describes hematoma formation under a laparoscopic trocar incision lateral to the umbilicus that progressed to an abscess and was treated with drainage, irrigation, and antibiotics. CONCLUSIONS: Choosing appropriate trocar types and insertion sites based on a thorough understanding of anterior abdominal wall anatomy may minimize the risk of vessel injury during operative laparoscopy. However, because of anatomical variation, strategies for managing vessel injuries and their sequelae are also necessary.

Second annual W.R. Ghent lecture on trauma. Abdominal organ injury: diagnosis, treatment and education.

In this lecture the author reviews aspects of education in the care of traumatized patients, with particular attention to abdominal injuries. He notes the lack of education in this aspect of medical care during the medical school years and the variable quality of trauma care education during residency training. The author outlines an organized approach to the teaching of trauma care, focusing on cognitive, psychomotor and affective education and the establishment of a uniform core curriculum for residents with the ultimate goal of enhancing patient care.

Predicting and preventing infection after abdominal vascular injuries.

Of 210 patients with major intra-abdominal vascular injuries, 111 (53%) survived more than 48 hours. Of these, 41 (37%) developed serious infections resulting in death or a hospital stay exceeding 14 days (mean, 55 +/- 49) in the 33 who survived. The most frequent serious infections were intraperitoneal and resulted in a 35% mortality rate (8/23). The 111 patients surviving 48+ hours were divided into two groups based on their initial E.D. BP and injuries. The "high-risk" patients (with no obtainable blood pressure on admission, five or more injuries or a colon injury with a systolic BP of 40 to 89 mm Hg) had a serious infection rate of 63% (25/40). This was significantly higher than the serious infection rate of 23% (16/71) in the remaining 71 "low-risk" patients (p less than 0.001). The patients were then evaluated for factors which surgeons might control. In the high-risk group, resuscitation adequate to produce an initial operating room (O.R.) systolic BP greater than 70 mm Hg and early control of bleeding so that less than 10 units of blood were used resulted in a serious infection rate of only 20% (2/10) versus 77% (23/30) in the other high-risk patients (p less than 0.01). In the low-risk patients, having an initial O.R. systolic BP greater than 70 mm Hg and using less than 10 units of blood resulted in a serious infection rate of 13% (6/48) versus 43% (10/23) in the others (p less than 0.05). High-risk patients failing to meet these resuscitation goals must be watched particularly carefully for development of infections.

Abdominal vascular injuries.

Trauma surgeons are occasionally faced with patients with abdominal vascular injuries. Important surgical issues in the successful management of these injuries require a thorough knowledge of the abdominal vascular anatomy and techniques of vascular repair, that surgical exploration be performed without delay, that the vascular injury be exposed rapidly with control of hemorrhage upon entering the abdomen, that efforts be made to reestablish perfusion initially to the structures at the highest risk of anoxic injury, and an understanding that it is occasionally necessary to perform temporary procedures while the general condition of a patient is being stabilized, with subsequent definitive care. The primary goal in the management of these patients should be hemorrhage control rather than maintenance of blood flow. The principles of abbreviated laparotomy with planned reoperation should be used in some patients with major abdominal vascular injuries. The decision to reestablish vascular continuity at a later time should balance anticipated functional outcome against potential complications.

Evisceration after abdominal stab wounds: is laparotomy required?

OBJECTIVES: To determine the incidence of intra-abdominal injury requiring laparotomy after an abdominal stab wound with evisceration. To identify clinical signs that increase the likelihood of an intra-abdominal injury in the presence of such a wound. METHODS: Information was collected prospectively over an 8-year period on all patients who presented to our urban level I trauma center with an abdominal stab wound and evisceration. This information included which organ eviscerated, presence of other indications for laparotomy, organs injured, and postoperative complications. All comparisons used the Fisher's exact chi2. RESULTS: A total of 81 patients were admitted with evisceration after an abdominal stab wound. Sixty-one patients (75%) had eviscerated omentum, 18 patients (22%) had eviscerated small bowel, and 2 patients (2%) had eviscerated colon. Sixty-two patients (76%) had evisceration as the sole indication for laparotomy, the remaining 19 patients (24%) had another indication such as hypotension or peritonitis. Overall, 63 patients (78%) had an intra-abdominal injury that required repair. This was true regardless of organ eviscerated (omentum = 77% vs. viscus = 80%, not significant) or clinical presentation (no other indication = 76% vs. another indication = 84%, not significant). CONCLUSION: The majority of patients who present with an evisceration after a stab wound to the abdomen require a laparotomy. This is true regardless of what has eviscerated or the presence of other clinical indications to operate. Evisceration should continue to prompt operative intervention.

The expediency of peritoneal lavage for blunt trauma in children.

Two hundred and thirty children, ten years of age or younger, suspected of having blunt abdominal injuries underwent diagnostic peritoneal lavage. Peritoneal lavage was 99.1 per cent accurate in determining the presence or absence of abdominal injuries. One patient had a false-positive peritoneal lavage. Sixty-nine of the 70 patients with blunt abdominal injuries, who underwent peritoneal lavage, had a positive peritoneal lavage; one patient had a false-negative peritoneal levage. Ninety-one per cent of the positive peritoneal lavages were grossly positive for hemoperitoneum. All 11 children with extraperitoneal abdominal injuries had positive peritoneal lavages from associated intraperitoneal injeries. The mortality for children with blunt abdominal injuries was 19.4 per cent. Intra-abdominal injuries were solely responsible for 29 per cent of the deaths and were a major contributing factor in an additional 21 per cent of the deaths. The routine use of diagnostic peritoneal lavage during the initial evaluation of blunt abdominal trauma was, in large part, responsible for the rapid, definitive treatment which -he children with abdominal injuries received. Sixty-five per cent of the children underwent exploratory laparotomy within one hour of admission to the hospital.

The impact of patient volume on surgical trauma training in a Scandinavian trauma centre.

OBJECTIVE: Some of the problems faced in trauma surgery are increasing non-operative management of abdominal injuries, decreasing work hours and increasing sub-specialisation. We wanted to document the experience of trauma team leaders at the largest trauma centre in Norway, hypothesising that the patient volume would be inadequate to secure optimal trauma care. METHODS: Patients registered in the hospital based Trauma Registry during the 2-year period from 1 August 2000 to 31 July 2002 were included. RESULTS: Of a total of 1667 patients registered, 645 patients (39%) had an Injury Severity Score (ISS)>15. Abdominal injuries were diagnosed in 205 patients with a median ISS of 30. An average trauma team leader assessed a total of 119 trauma cases a year (46 patients with ISS>15) and participated in 10 trauma laparotomies. CONCLUSION: Although the total number of trauma cases seems adequate, the experience of the trauma team leaders with challenging abdominal injuries is limited. With increasing sub-specialisation and general surgery vanishing, fewer surgical specialties provide operative competence in dealing with complicated torso trauma. A system of additional education and quality assurance measures is a prerequisite of high quality, and has consequently been introduced in our institution.

Death in the operating room: an analysis of a multi-center experience.

To characterize causes of death in the operating room (OR) following major trauma, a retrospective review of admissions to eight academic trauma centers was conducted to define the etiology of death and challenges for improvement in outcome. Five hundred thirty seven OR deaths of 72,151 admissions were reviewed for mechanism of injury, physiologic findings, resuscitation, patterns of injury, surgical procedures, cause of death, and preventability. Blunt injuries accounted for 61% of all injuries, gunshot wounds (GSW) accounted for 74% of penetrating injuries. Sixty two percent of all patients arrived in shock. Average blood pressure (BP) was 52 mm Hg at the scene and 60 mm Hg on admission, with the period of shock > 10 minutes in 74%. Only 56% were resuscitated to a BP > 90 mm Hg before surgery. Average time to the OR was 30.1 minutes and mean best postresuscitation pH was 7.18. Mean best OR temperature was 32.2 degrees C. Recurrent injury patterns judged as the primary cause of patient death included head/neck injury (16.4%), chest injury (27.4%), and abdominal injury (53.4%). Actual cause of death was bleeding (82%), cerebral herniation (14.5%), and air emboli (2.2%). A different strategy for improved outcome was identified in 54 patients with the following conclusions: (1) delayed transfer to the OR remains a problem with significant BP deterioration during delay, particularly following interfacility transfer; (2) staged injury isolation and repair to allow better resuscitation and warming may lead to improved results; (3) combined thoraco-abdominal injuries, particularly with thoracic aortic disruption, often require a different sequence of management; (4) aggressive evaluation of retroperitoneal hematomas is essential; (5) OR management of severe liver injuries remains a technical challenge with better endpoints for packing needed; and (6) resuscitative thoracotomy applied to OR patients in extremis from exsanguination offers little.

[Abdominal trauma].

While a great part of the Anglo-American medical literature addresses the topic of penetrating trauma the German speaking countries rather publish on blunt abdominal injury. The presented paper discusses the strategic principles of acute clinical management of abdominal trauma on the combined basis of own research results and a comprehensive review of the literature. Blunt abdominal injuries in most cases from a part in the pattern of multiple trauma. The early, first-hours mortality is most often caused by severe traumatic brain injury or abdominal trauma with massive hemorrhage. The prehospital management of penetrating injuries is characterized rather by the concept of 'load and go', whereas the onscene stabilization of the patient with blunt abdominal injury should precede transport to the adequate hospital. On arrival in the accident and emergency room an immediate blood transfusion is recommended for hemodynamically unstable patients. If then a stabilization is not achieved, an emergency laparotomy should follow. Abdominal stab injuries should be explored by laparoscopy if an intraperitoneal lesion is suspected. If then the possibility of an intestinal lesion is present a laparotomy should be performed directly thereafter. Firearm injuries require open revision in almost all cases. The standard diagnostic technique in blunt abdominal trauma is sonography, assisted by computed tomography and, if indicated, angiography in hemodynamically stable patients. Isolated abdominal injuries without hemodynamic or coagulation disorders allow conservative treatment in the intensive care setting. In severe multiple trauma as well as in manifest shock even the smallest fluid detection should lead to laparotomy. The surgical treatment of splenic rupture is still a matter of discussion. Splenectomy is indicated in patients with severe concomitating injuries or shock whereas in the remainder of cases the total or partial preservation of the spleen should be pursued. Hepatic injuries offer a broad spectrum of operative interventions, ranging from superficial hemostatic measures over compression techniques like 'packing' and 'mesh-wrapping' to atypical and anatomical resections and to liver transplantation in exceptional cases. Lesions of tubular organs and the pancreas pose especially difficult diagnostical problems but regularly allow a rather easy operative treatment.

Iatrogenic operative injuries of abdominal and pelvic veins: a potentially lethal complication.

PURPOSE: Epidemiologic studies of vascular injuries are usually limited to those caused by trauma. The purpose of this study was to review the management and clinical outcome in patients with operative injuries to abdominal and pelvic veins. METHODS: Clinical data and outcome in all patients with iatrogenic venous injuries during abdominal and pelvic operations between 1985 and 2002 were reviewed. RESULTS: Forty patients (21 men, 19 women; mean age, 51 years [range, 27-87 years]) sustained 44 venous injuries. Injuries occurred during general (30%), colorectal (23%), orthopedic (20%), gynecologic (15%), and other (12%) operations. Factors leading to injury included oncologic resection (65%), difficult anatomic exposure (63%), previous operation (48%), recurrent tumor (28%), and radiation therapy (20%). All patients had substantial bleeding (mean, 3985 mL; range, 500-20,000 mL). Injuries were located in the inferior vena cava (n = 6), portal vein (n = 7), renal vein (n = 1), and iliac vein (n = 30). Repair was performed with venorrhaphy (64%), end-to-end anastomosis (14%), interposition graft (20%), and vessel ligation (2%). Seven patients (18%) died of injury-related causes, including multisystem organ failure (n = 4), uncontrollable bleeding (n = 2), and pulmonary embolism (n = 1). Thirteen patients (32.5%) had major injury-related complications, including repeat exploration because of bleeding (n = 6), multisystem organ failure (n = 6), and venous thrombosis (n = 4). In two patients (5%) unilateral lower extremity edema developed, with no evidence of thrombosis. There was no late graft or venous thrombosis. Variables associated with increased risk for death were massive bleeding, acidosis, hypotension, and hypothermia (P <.05). CONCLUSION: Operative injuries of abdominal and pelvic veins occur in patients undergoing oncologic resection and those with difficult anatomic exposure, owing to previous operation, recurrent tumor, or radiation therapy. Massive blood loss, acidosis, hypotension, and hypothermia are associated with increased risk for death. Repair of venous injuries offers durable results with low incidence of graft or venous thrombosis.

Delayed rupture or delayed diagnosis of rupture of the spleen.

Delayed rupture of the spleen was seen in only six of 302 patients undergoing splenectomy for splenic injury following blunt abdominal trauma. Only one of these six patients was asymptomatic for two days following the accident. This is an incidence of 2 per cent delayed rupture as compared with the 15 per cent quoted in the literature. An aggressive approach to the diagnosis of intra-abdominal injury has helped to eliminate the delay in recognition of rupture of the spleen. Peritoneal lavage has accurately identified those patients with intra-abdominal injury. We conclude that delayed rupture of the spleen is, in reality, usually a delay in diagnosis of splenic rupture.

Upper abdominal aortic injury during spinal surgery.

We describe a rare case of iatrogenic injury to the upper abdominal aorta during spine surgery. The case is reviewed, and diagnosis as well as management of this injury is discussed. No similar previous reports of iatrogenic injury to the upper abdominal/lower thoracic aorta were identified in the literature. Reports of iatrogenic injury to the lower abdominal aorta during spinal surgery have been frequent. With more aggressive operative treatment of spinal disorders, injury to the upper abdominal/lower thoracic aorta may become more common. Timely diagnosis and treatment are essential to prevent both early and delayed complications and death.

Abdominal aortic injury associated with transverse lumbar spine fracture--imaging findings.

The association of abdominal aortic injury with transverse fractures of the lumbar spine is not well recognized. Three cases are presented with description of a mechanism common to both injuries that may explain this association--that of distraction and hyperflexion, such as occurs in seat-belt injuries. Whenever a transverse lumbar spine fracture following such a mechanism of injury is recognized, the co-existence of an injury to the abdominal aorta should be excluded by aortography if there is any doubt concerning the integrity of the peripheral pulses. This is best performed prior to laparotomy for any associated intraperitoneal injuries. Repeated clinical examination may detect deterioration in those cases with initially normal pulses. Ultimately, detection of the aortic injury rests on a high index of suspicion.
