Pediatric blunt liver injury: establishment of criteria for appropriate management

There is no consensus regarding the most appropriate management of pediatric blunt liver injury. This study addresses this issue by reviewing our experience with blunt liver trauma in relationship to the grade of injury. Forty-one pediatric patients with blunt abdominal trauma and documented liver injury were managed from 1979 to 1989. Fifteen (37%) underwent celiotomy. Three children had extensive parenchymal injuries (grade IV or V) requiring resection and three others died intraoperatively, secondary to exsanguinating hemorrhage of associated injuries (grade V) to the hepatic veins and inferior vena cava. The need for celiotomy was obvious in these patients. In 9 of the 15 children who underwent exploration (60%), bleeding from the liver injury (grade II or III) had ceased by the time of celiotomy. These children did not appear to benefit from the operation. Twenty-six of the 41 patients (63%) were selected for nonoperative management because they were hemodynamically stable after initial resuscitation and did not show signs of associated intraabdominal injuries requiring surgical intervention. These children underwent evaluation by abdominal computed axial tomography scan (grade I, II, III, and IV injuries). Blood transfusions were given to keep the hematocrit above 30%. Seventeen of the 26 children managed nonoperatively (65%) did not require blood replacement. The mean (+/- SEM) transfusion volume for the remaining nine children was 14.8 +/- 2.5 mL/kg. Blunt liver injury represents a spectrum from a minimal parenchymal hematoma to massive liver disruption. We conclude that celiotomy is necessary for hepatic injury hemodynamically stable injured children with transfusion requirements less than 40 mL/kg can be managed nonoperatively in an appropriate setting.

Severe hepatic trauma: a multi-center experience with 1,335 liver injuries

The experience of six regional trauma centers with severe hepatic trauma was reviewed to identify trends in management, mortality, and postoperative complications. During the 5-year period ending June 1987, 210 complex liver injuries were identified at laparotomy. There were 92 Class III, 59 Class IV, and 59 Class V injuries. Mechanism of injury was blunt in 101 (48%) patients and penetrating in 109 (52%). Shock was observed in 38%, 46%, and 85% of Class III, IV, and V patients, respectively. Emergency department thoracotomy was performed in 31 patients. There was only one (3%) survivor. Resuscitative operating room thoracotomy was performed in 34 patients with three (9%) survivors. Class III injuries were most frequently treated with hepatotomy and individual vessel ligation (41%) and deep liver suturing (25%). Class IV injuries were most often managed by resectional debridement (36%). Class V injuries required caval shunt placement in 38 (64%) patients. There were only four (10%) survivors after caval shunt placement. There were 20 (59%) survivors of 34 patients treated with packing placed as an adjunct after hepatic injury repair. There was no significant increase in the incidence of abscess formation after perihepatic packing. Routine peritoneal drainage was used in 94% of patients. Overall mortality rates for Class III, IV, and V injuries were 25%, 46%, and 80%, respectively (p less than 0.01). Death rates due to the liver injury in Class III, IV, and V patients were 7%, 30%, and 66%, respectively (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)     

Significant trends in the treatment of hepatic trauma. Experience with 411 injuries.

Several significant advances in the treatment of hepatic injuries have evolved over the past decade. These trends have been incorporated into the overall treatment strategy of hepatic injuries and are reflected in experiences with 411 consecutive patients. Two hundred fifty-eight patients (63%) with minor injuries (grades I to II) were treated by simple suture or hemostatic agents with a mortality rate of 6%. One hundred twenty-eight patients (31%) sustained complex hepatic injuries (grades III to V). One hundred seven patients (83.5%) with grades III or IV injury underwent portal triad occlusion and finger fracture of hepatic parenchyma alone. Seventy-three surviving patients (73%) required portal triad occlusion, with ischemia times varying from 10 to 75 minutes (mean, 30 minutes). The mortality rate in this group was 6.5% (seven patients) and was accompanied by a morbidity rate of 15%. Fourteen patients (11%) with grade V injury (retrohepatic cava or hepatic veins) were managed by prolonged protal triad occlusion (mean cross-clamp time, 46 minutes) and extensive finger fracture to the site of injury. In four of these patients an atrial caval shunt was additionally used. Two of these patients survived, whereas six of the 10 patients managed without a shunt survived, for an overall mortality rate of 43%. Over the past 4 years, six patients (4.7%) with ongoing coagulopathies were managed by packing and planned re-exploration, with four patients (67%) surviving and one (25%) developing an intra-abdominal abscess. One additional patient (0.8%) was managed by resectional debridement alone and survived. During the past 5 years, 25 hemodynamically stable and alert adult patients (6%) sustaining blunt trauma were evaluated by computed tomography scan and found to have grade I to III injuries. All were managed nonoperatively with uniform success. The combination of portal triad occlusion (up to 75 minutes), finger fracture technique, and the use of a viable omental pack is a safe, reliable, and effective method of managing complex hepatic injuries (grade III to IV). Juxtahepatic venous injuries continue to carry a prohibitive mortality rate, but nonshunting approaches seem to result in the lowest cumulative mortality rate. Packing and planned reexploration has a definitive life-saving role when used adjunctively in the presence of a coagulopathy. Nonoperative management of select hemodynamically stable adult patients, identified by serial computed tomography scans after sustaining blunt trauma is highly successful (95-97%).     

Selective non-operative management of liver gunshot injuries

BACKGROUND: In contrast to non-surgical treatment of blunt liver trauma, non-operative management (NOM) of liver gunshot injuries (LGSIs) is not widely accepted. This prospective study evaluated an experience of NOM of gunshot wounds to the liver. METHODS: All patients presenting with LGSIs who were haemodynamically stable with no evidence of peritonism underwent a protocol of NOM. RESULTS: Thirty-three patients (mean age 25 (range 13-50) years) were enrolled over a 36-month period. Fourteen had grade III injuries according to the American Association for the Surgery of Trauma (AAST) classification, whereas 11 and eight patients sustained major (AAST IV/V) and minor (AAST I/II) injuries respectively. NOM was successful in 31 of 33 patients. Two patients required delayed laparotomy for indications unrelated to the hepatic trauma. One patient died from necrotizing fasciitis, which appeared unrelated to the liver injury. CONCLUSION: This study demonstrated that, regardless of the grade of liver trauma, NOM is safe and effective in appropriately selected patients with LGSI treated in centres with suitable facilities.     

Operative and nonoperative management of blunt hepatic trauma in adults: a single-center report

Background/Purpose Liver trauma, especially that as result of road traffic accidents, still remains a complicated problem in severely injured patients. The aim of this study was to extract useful conclusions from the management in order to improve the final outcome of such patients. Methods Details for 86 patients with blunt hepatic trauma who were examined and treated in our department during a 6-year period were analyzed. We retrospectively reviewed the severity of liver injury, associated injuries, treatment, and outcome. Results Forty-nine liver injuries (57%) were of low severity (grades I and II), while 37 (43%) were of high severity (grades III, IV, and V). Liver trauma with associated injury of other organs was noted in 62 (72.1%) patients. Forty-three (50%) patients underwent an exploratory laparotomy within the first 24 h of admission. Thirty-five (71.4%) of the 49 patients with low-grade hepatic injuries were managed conservatively; no mortality occurred. Six (14%) of forty-three patients with liver trauma initially considered for conservative management required surgery due to hemodynamic instability. Five (13.5%) of 37 patients who were finally managed nonoperatively required adjunctive treatment for biloma, hematoma, or biliary leakage; no mortality occurred. The overall mortality rate was 9.3%; mortality rates of 5.8% and 3.5% were due to liver injuries and concomitant injuries, respectively. Conclusions Severe hepatic injuries require surgical intervention due to hemodynamic instability. Low-grade injuries can be managed nonoperatively with excellent results, while patients with hepatic trauma with associated organ injuries require surgery, because they continue to have significantly higher mortality.     

Liver Trauma: Experience in 348 Cases

Liver trauma, the main cause of death in patients suffering abdominal injury, remains an unresolved problem, especially in its most severe forms. The objective of this study was to probe effective surgical procedures and improve the outcome for patients with severe hepatic injury. A retrospective study of 348 patients with hepatic trauma seen in our institution during the past 12 years was carried out. Of these 348 patients, 259 (74.4%) underwent surgery. To manage severe liver trauma (American Association for the Surgery of Trauma grade III to grade V), procedures such as packing of the laceration with omentum, hepatectomy or direct control of bleeding vessels within the liver substance by means of the Pringle maneuver, selective hepatic artery ligation, retrohepatic caval repair with total hepatic vascular occlusion, and perihepatic packing were selected and combined based on the specific injury. In the 259 patients treated operatively, the survival rate was 86.9% (225/259); and 15 of 40 with retrohepatic venous injury (RHVI) were cured with the maximum blood transfusion of 60 units. In 42 patients treated by perihepatic packing, the bleeding was stopped in 20 of 25 (80%) with RHVI and in 14 of 17 (82%) without such injury (p > 0.75). The percentage of failure of nonoperative management was 17.2% (17/99); and it was 46.7% (14/30) in patients with grade III–V injury. Death occurred in 3 (50%) of 6 failures of grade IV–V injury. The overall mortality rate was 11.8% (41/348), and 51% of the deaths were due to exsanguination. The results suggest that severe hepatic injuries, especially grade IV–V injuries, usually require surgical intervention; reasonable surgical procedures based on classification of liver trauma and combined application of techniques can increase the survival rate; and perihepatic packing is effective in dealing with RHVI.

Ultrasonography for interval assessment in the nonoperative management of hepatic trauma

Abdominal ultrasonography (US) is gaining widespread acceptance as a valuable diagnostic tool in the initial evaluation of trauma victims. We investigated the utility of US as a follow-up radiologic study in nonoperative hepatic trauma. Patients with liver injury designated for nonoperative management were prospectively studied over a 2-year period at our primary adult resource center for trauma. Computed tomography (CT) and radiologist-performed US were obtained at admission and at 1 week. The ability of US to detect lesions, fluid, and complications was evaluated by comparing with the corresponding CT. Twenty-five hepatic trauma patients in the study were successfully managed nonoperatively and had both initial and follow-up US and CT scans: 1 (4%) grade I, 5 (20%) grade II, 7 (28%) grade III, 7 (28%) grade IV, and 5 (20%) grade V. Four complications developed [biloma (3) and biliary fistula (1)] in 3 patients with grade IV injury and 1 with a grade II injury. Interval US appropriately detected a complication or confirmed the absence of complication in all (13/13, 100%) patients with low-grade (I-III) injury and only missed a small biloma in one patient with a grade IV injury. Interval US and CT agreement was 92 per cent for change in hemoperitoneum or parenchymal lesion. Ultrasonography is a convenient imaging modality in the evaluation of hepatic trauma. US is sufficient to detect or exclude complications in low-grade injuries. In high-grade injuries, US may be an adjunct to CT for definitive interval assessment.     

Predictive factors of morbidity and mortality in grade IV and V liver trauma undergoing perihepatic packing: Single institution 14 years experience at European trauma centre

PurposeMajor liver trauma in polytraumatic patients accounts for significant morbidity and mortality. We aimed to assess prognostic factors for morbidity and mortality in patients with severe liver trauma undergoing perihepatic packing.MethodsProspectively collected records of 293 consecutive polytrauma patients with liver injury admitted at a level I trauma centre between 1996 and 2008 were reviewed. 39 patients with grade IV–V AAST liver injury and treated with peri-hepatic packing were identified and included for analysis. Univariate and multivariate analyses were performed to assess prognostic factors for morbidity and mortality.ResultsMean age of patients was 41 years. 34 patients were haemodynamically unstable at initial presentation. Ten of 39 patients were treated with angiographic embolization in addition to perihepatic packing. The overall mortality rate was 51.3%. Liver-related death occurred in 23.1%. Overall and liver-related morbidity rates were 90% and 28%, respectively. Glasgow Coma Scale (GCS), respiratory rate, packed red blood cells (PRBC) transfusion, pH and Base Excess (BE), Revised Trauma Score (RTS) and Trauma Injury Severity Score (TRISS), need for angiographic embolization as well as early OR and ICU admission were associated with significant decrease of early mortality.ConclusionsRevised Trauma Score, haemodynamic instability, blood pH and BE are important prognostic factors influencing morbidity and mortality in polytrauma patients with grade IV/V liver injury. Furthermore, fast and effective surgical damage control procedure with perihepatic packing, followed by early ICU admission is associated with lower complication rate and shorter ICU stays in this patient population.     

Chirurgische Therapie, prognostische Faktoren und Ergebnisse beim Lebertrauma

Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Extensive experience in liver surgery is a prerequisite for the management of these injuries. The medical records of 68 consecutive patients with hepatic trauma were retrospectively reviewed for the severity of liver injury, management, morbidity, mortality, and risk factors.Of the patients, 14 were treated conservatively and 52 surgically (24 suture/fibrin glue, 16 perihepatic packing, 11 resections, 1 liver transplantation). Two patients died just before emergency surgery could be performed. Overall mortality was 21% (14/68), and 13, 14, 6, 27, and 50% for types I, II, III, IV, and V injuries, respectively. Only nine deaths (all type IV and V) were liver related, while four were caused by extrahepatic injuries and one by concomitant liver cirrhosis. With respect to treatment, conservative management, suture, and resection had a low mortality of 0, 4, and 9%, respectively. In contrast, mortality was 47% in patients in whom only packing was performed (in severe injuries). Stepwise multivariate regression analysis proved prothrombin values <40%, ISS scores >30, and transfusion requirements of more than 10 red packed cells to be significant risk factors for post-traumatic death.Type I-III hepatic injuries can safely be treated by conservative or simple surgical means. However, complex hepatic injuries (types IV and V) carry a significant mortality and may require hepatic surgery, including liver resection or even transplantation. Therefore, patients with severe hepatic injuries should be treated in a specialized institution.     

Nonoperative management of pediatric blunt hepatic trauma

The purpose of this study was to examine the effect of operative versus nonoperative management of blunt hepatic trauma in children including transfusion practices. We reviewed the experience at our American College of Surgeons-verified Level I trauma center with pediatric commitment over a 5-year period. Children < or = 16 years of age suffering blunt liver injury as documented on admission CT scan were included in the study. Liver injuries identified on CT scan were classified according to the American Association for the Surgery of Trauma's Organ Injury Scaling system. All data are presented as mean +/- standard error. One case of pediatric liver trauma not identified on CT was excluded (prehospital cardiopulmonary resuscitation). Twenty-seven patients were included [age 9.3 +/- 1.0 years (range 3-16)]. Mechanisms of injury included motor vehicle crash (14), pedestrian struck by motor vehicle (7), bicycle crash (4), fall from height (1), and pedestrian struck by falling object (1). Trauma Score was 11.5 +/- 0.3. Distribution of Liver Injury Grade was as follows: grade I, 13; grade II, 9; grade III, 3; grade IV, 2; and grade V, 0. All five patients who underwent operative management had multiple organ injuries; three had concomitant splenic injury requiring operative repair; the remaining two had small bowel injury requiring repair. Hepatorrhaphy did not correlate with severity of liver injury: grade I, n = 1; II, n = 2; III, n = 1; and IV, n = 1. Three operated patients received blood transfusions. Twenty-two patients were managed with nonoperative treatment, of these only one required blood transfusion. No patients in the study died, three were transferred to subacute rehabilitation, one was transferred to another hospital, and 23 were discharged home. Our findings indicate that a majority of children with blunt hepatic injury as documented on CT scan can be managed with nonoperative treatment, and few require blood transfusions. Patients with multiple organ injury including simultaneous splenic injury are likely ideally managed through operative exploration and repair, whereas those with isolated liver injuries can be successfully managed nonoperatively.     

Selective management of blunt hepatic injuries including nonoperative management is a safe and effective strategy

BACKGROUND: The justification and preference for operative versus nonoperative management of hepatic injuries caused by blunt trauma remains ambiguous. This review assesses the outcome of operative and nonoperative management of liver injury after blunt trauma. METHODS: We retrospectively reviewed the demographics, severity of injury, severity of liver injury, associated concomitant injuries, management scheme, and outcome of patients with documented hepatic injury from 1993 to 2003. RESULTS: The overall mortality rate was 9.4%, with 3.7% caused by the liver injury itself. Fifty-nine percent (330 of 561) of liver injuries were of low severity (grades I and II), with an overall mortality rate of 6.6% caused by concomitant injuries and liver-related mortality of 0%. Forty-one percent (231 of 561) of liver injuries were high-severity injuries (grades III, IV, and V). Mortality for nonoperative management of high-severity liver injuries was 2.2%. If operative intervention was required because of hemodynamic instability or concomitant injuries then the mortality rate was significantly higher at 30%. Forty-two of the 378 (11%) liver injuries treated nonoperatively required an adjunctive procedure for successful management. CONCLUSIONS: Selective management of liver injuries presented a low liver-related mortality rate. Low-grade injuries can be managed nonoperatively with excellent results. High-grade injuries can be managed nonoperatively, if operative intervention is not required for hemodynamic instability or associated injuries, with a low mortality. In these patients, adjunctive procedures will be required selectively for successful nonoperative management of high-grade liver injuries. High-grade injuries requiring operative management because of hemodynamic instability or concomitant injuries continue to have significantly higher mortality.     

Prognosis and therapy of liver injury in patients with multiple injuries

Between 1.7. 1986 and 31.10. 1989 abdominal trauma was seen in 108 (35.8%) of 300 polytraumatized patients, 44 of these showed rupture of the liver. 23 patients belonged to grade I-III (Moore-classification) and 11 patients to grade IV. Extensive bilobar parenchymal destruction (grade V) was found in 10 patients including 6 patients with retrohepatic vena cava injury. 80% of all patients with liver trauma had intraabdominally associated injuries. In Grade I-II (n = 4) patients were treated conservatively and continuously observed by ultrasound. Injuries graded to III (n = 19) and IV (n = 11) were mostly treated by simple suture or segmental resection. In grade V hemihepatectomy was done in 4 cases, in 2 cases combined by packing and in 1 patient packing only. In 3 patients no adequate therapy was possible. The mortality rate being 36% (n = 16), hemorrhagic complications were the most common cause of death (7 of 16 patients). This was due only to the patients graded to V. In comparison the prognostic factor in grade I-IV ruptures were the associated injuries. In all these cases hemorrhage was stopped by a conservative, organ-retaining therapy. No further hemorrhage occurred. Liver packing was mainly used as additional treatment in cases of coagulopathy after resection. Further indications are extensive bilobar parenchymal destruction without the possibility of primary reconstruction and temporary hemostasis to allow transport to a specialized hospital.     

Blunt liver trauma at sunnybrook Medical Centre: a 13 year experience

Between June 1, 1976 and June 30, 1989 The Regional Trauma Unit at Sunnybrook Medical Centre in Toronto, Ontario, Canada received 3730 patients. Of these 335 (9%) sustained a liver injury, 95% being due to blunt trauma. Open peritoneal lavage was performed on 80% of liver trauma patients (267/335), 99% being true positive. A laparotomy was performed on 97% of patients (324/335). Major surgical treatment was required in 132 patients (41%) and minor treatment in 192 patients (59%). The remaining 11 patients were treated conservatively (n = 3) or died during resuscitation (n = 8). Morbidity directly related to the liver injury was seen in 29 of 249 surviving patients (11%) although overall morbidity was 27% (67/249). Reoperation was required in 6% (14/249) with abscess or hematoma accounting for 11 of 14 operations. The overall mortality rate was 26% (86/335). Eighty two percent of patients (n = 276) had a grade I, II or III liver trauma according to Moore's classification with a mortality of 12% (n = 32). The remaining 18% of patients (n = 59) had a grade IV or V liver trauma with a mortality of 44% (n = 26). Of the 86 deaths, head injury accounted for 48 (56% of deaths); liver hemorrhage for 17 (20%), liver sepsis for 1 (1%) and other causes for 20 deaths (23%). Thus death due to the liver injury itself (hemorrhage and sepsis) occurred in 18 out of 335 patients (5% overall). Head injury accounted for the death of 48 out of 335 patients (14% overall). Over the past 13 years a trend has occurred at our institution whereby we are seeing less liver trauma in our population of multiply injured patients from 12% (1976-1983) down to 7% (1985-1989); with a gradual decline in overall mortality from 32% (1976-1983) to 19% (1985-1989), whereas the percentage of deaths due to head injuries and liver injury have increased.     

Grade IV Renal Injuries: Evaluation, Treatment, and Outcome

Of our last 2483 renal trauma patients, 113 had grade IV injuries. In most the mechanism was a penetrating injury (60%: 30% gunshot, 30% stab wounds). Associated injuries were common (80%) and hospital stays prolonged, averaging 16 days. Most of the patients (70%) required transfusion, some massively (average volume 4.4 liters, range 0-30 liters). Surprisingly, not all patients with grade IV renal injuries had gross hematuria: 25% had microhematuria, and 4% had neither microscopic nor gross hematuria. Computed tomography (CT) diagnosed the injury correctly in 100% of the patients in whom it was performed; when CT was not available, "one-shot" intraoperative intravenous pyelography (IVP) demonstrated grossly abnormal findings in 90%. Renal exploration was performed in 78%, resulting in 69% renorrhaphy and 9% nephrectomy rates in our 113 patients. Almost all those with penetrating trauma required exploration (97%), whereas only 50% of those with blunt trauma did so. The overall complication rate and kidney-specific complication rate did not differ significantly between patients who were observed and those who underwent surgery. Complications rates were similar in grade IV renal laceration patients and grade III patients. Delayed complications after hospital discharge were not seen, although follow-up was rare in this inner-city trauma population. Among the 21% of patients in whom postoperative nucleotide renal function scans were available, function was generally good (average 36%). Only patients who underwent concomitant vascular repair had poor function (below 20%).     

Severe hepatic trauma：surgical strategies

Objective:To probe into effective surgical procedures and improve the outcome of treatment for patients with severe hepatic injury.Methods:A retrospective study involving 113 patients with severe hepatic trauma(AAST grade IV and V) during the past 12 years was carried out.Ninety-eight patients underwent surgical treatment.Surgical interventions including hepatectomy or direct control of bleeding vessels by finger fracture technique with Pringle maneuver, selective ligation of hepatic artery,retrohepatic caval repair with total hepatic vascular occlusion,and perihepatic packing were mainly used.Results:In the 98 patients treated operatively,the survival rate was 69.4%(68/98).Among 40 patients with juxtahepatic venous injury(JHVI),15 were cured with the maximum blood transfusion of 12 000 ml.Eight cases of Grade IV injury treated nonoperatively were cured.The percentage of failure of nonoperative management was 42.9%(6/14).The overall mortality rate was 32.7%(37/113),and 57% of the deaths were due to exsanguinations.Conclusions:Reasonable surgical procedures based on classification of hepatic injuries can increase the survival rate of severe liver trauma.Accurate perlihepatic packing is effective in dealing with JHVI.     

A multidisciplinary approach in the management of hepatic injuries

We reviewed 87 patients with hepatic injuries who were admitted to King Chulalongkorn Memorial Hospital, Bangkok, Thailand, from January 1995 to December 1999; 76% of them had sustained blunt trauma and 24% penetrating trauma. Their injury severity scores (ISS) ranged from 4 to 57 (mean 20.94+/-12.8); 50% of them were in shock on arrival; 8.1, 28.7, 25.3, 19.5, and 18.4% suffered from hepatic injuries graded I, II, III, IV, and V, respectively. Seventeen patients (19.5%) were successfully managed non-operatively; three of them underwent hepatic angiography, which in two revealed leakage of contrast medium from the right hepatic artery; both were successfully treated by embolization. One patient had bile leakage and collection, which was successfully treated by ultrasound-guided percutaneous drainage. Seventy patients (80.5%) underwent exploratory laparotomy; nine of them died in the operating room. Of the remaining 61 who left the operating room alive, 21 had perihepatic packing, which was frequently used in those with injuries to segments V, VI, VII, and VIII (Couinaud's nomenclature). Eight patients who had packing and one who had not died in the postoperative period. Two patients who had packing underwent subsequent hepatic angiography with embolization before successful pack removal. The overall mortality was 20.7%. The mortality in complex hepatic injuries (grades IV and V) was 13 out of 33 (39.4%). We believe that non-operative management should be considered in haemodynamically stable patients. Angiography with embolization is invaluable in improving outcome in both non-operative and operative patients. Perihepatic packing is life-saving in complex hepatic injuries that cannot be effectively treated by simple surgical procedures. Finally, ultrasound- or CT-guided percutaneous drainage of bile leakage or collections spared a number of patients from open and complicated surgery.     

Combined midline-transverse surgical approach for severe blunt injuries to the right liver

BACKGROUND: Although nonoperative treatment has been a major advance in the management of liver trauma, emergency surgery is still required for unstable patients. Severe hepatic lesions located in the right lobe, notably juxtahepatic venous injuries, are difficult to access and still carry a high mortality. METHODS: We describe a surgical approach for severe blunt injury to the right liver by a combined midline-transverse incision. This techniques allows simple, easy, and rapid mobilization and compression of the liver to control bleeding. RESULTS: This technique was used in 10 patients with blunt liver trauma, with grade III (n = 2), IV (n = 5), and V (n = 3) injuries. Mean intraoperative blood transfusion required was 21 units. Six patients underwent mandatory anatomic resection, three patients were treated by hepatic suture, and one patient was treated by packing. This patient developed brain death after surgery and was the only mortality. CONCLUSION: This technique is efficient and less cumbersome than shunting approaches.     

Use of Sengstaken-Blakemore Intrahepatic Balloon: An Alternative for Liver-Penetrating Injuries

Background

Severe lesions in the liver are associated with a high mortality rate. Alternative surgical techniques such as the use of an intrahepatic balloon may be effective and reduce mortality in severe hepatic lesions. This study aimed to demonstrate the experience of a university hospital in the use of the Sengstaken-Blakemore balloon in patients with transfixing penetrating hepatic injury as an alternative way to treat these challenging injuries.

Methods

A retrospective study based on the trauma registry of a university hospital was performed. All patients admitted with hepatic penetrating injuries and treated with the Sengstaken-Blakemore balloon within the period 1990–2010 were reviewed.

Results

Forty-six patients with transfixing hepatic injuries were treated with the Sengstaken-Blakemore balloon in the study period. The most frequent cause of injury was gunshot wound (87?% of the patients). The mean trauma scores on admission were Revised Trauma Score (RTS)?=?7.12?±?1.46, Injury Severity Score (ISS)?=?22.4?±?9.7, and Abdominal Trauma Index (ATI)?=?19.5?±?11. According to the severity of the hepatic trauma, 71.8?% of patients had grade III, 23.9?% grade IV, and 4.3?% grade V injuries. Associated abdominal injuries were found in 89.1?% of the patients. The most frequent liver-related complications were hepatic abscess postoperative bleeding (8.6?%), biliary fistula (8.6?%), (4.3?%), and biliary peritonitis (2.1?%). Surgical reintervention was necessary in 14 patients (31.1?%). From those 14, only 3 had the balloon removed. The overall morbidity and mortality rates were 56.5?% and 23.9?% (11 patients), respectively.

Conclusion

The knowledge of alternative surgical techniques is essential in improving survival in patients with severe penetrating hepatic injuries. The use of intrahepatic balloon is a viable surgical strategy.
