Definitive Surgery for Liver Trauma in a Tertiary HPB Center (with video).

Background: Surgery for severe liver trauma remains challenging even for HPB surgeons, mainly due the hemodynamical instability, involvement of major vascular and biliary elements, impaired background liver and frequent anatomical variants. In this setting, despite conservative policy, major liver resection is still required in selected cases. Also salvage liver transplantation may be needed. Our study aims to analyze the results after definitive surgery for hepatic injury (HI) in a tertiary HPB center. Methods: Sixty-six patients with HI were admitted and treated in our center between June 2000 and June 2021. The median age was 29 years (mean 35, range 10-76). The male/female ratio was 50/16. According to the American Association for the Surgery of Trauma (AAST) system, HIs were grade II in one patient (1.5%), grade III in 11 pts (16.7%), grade IV in 25 pts (37.9%), and grade V in 29 pts (43.9%); no patient had grade I or VI HI. Results: Fifty-two pts (78.8%) benefitted from surgery and 14 pts (21.2%) from non-operative treatment (NOT). Perihepatic packing was previously performed in 38 pts (73.1%). Surgery consisted in hepatic resections (HR) in 51 pts (77.3%) and liver transplantation in one patient (1.5%). The rate of major HR was 51.9% (27 HRs). The overall major morbidity and mortality rates were 33.3% (20 pts) and 13.6% (9 pts), respectively. For surgery, the major complication rate was 35.3% (18 pts), while for major and minor HR were 40.7% (11 pts) and 29.2% (7 pts), respectively; the mortality rate was 15.7% (8 pts). After NOT, the major morbidity and mortality rates were 14.3% (2 pts) and 7.1% (1 pt), respectively. Conclusions: Hepatic resections, especially major ones and/or involving vascular and biliary reconstructions, as well as non-operative treatment for severe hepatic injuries, are to be carried out in tertiary HPB centers, thus minimizing the morbidity and mortality rates, while having the liver transplantation as salvage option.

Severe liver trauma with complex portal and common bile duct avulsion: A case report and review of the literature.

BACKGROUND: Given its size and location, the liver is the third most injured organ by abdominal trauma. Thanks to recent advances, it is unanimously accepted that the non-operative management is the current mainstay of treatment for hemodynamically stable patients. However, those patients with hemodynamic instability that generally present with severe liver trauma associated with major vascular lesions will require surgical management. Moreover, an associated injury of the main bile ducts makes surgery compulsory even in the case of hemodynamic stability, thereby imposing therapeutic challenges in the tertiary referral hepato-bilio-pancreatic centers' setting. CASE SUMMARY: We present the case of a 38-year-old male patient with The American Association for the Surgery of Trauma grade V liver injury and an associated right branch of portal vein and common bile duct avulsion, due to a crush polytrauma. The patient was referred to the nearest emergency hospital and because of the hemorrhagic shock, damage control surgery was performed by means of ligation of the right portal vein branch and right hepatic artery, and hemostatic packing. Afterwards, the patient was referred immediately to our tertiary hepato-bilio-pancreatic center. We performed depacking, a right hepatectomy and Roux-en-Y hepaticojejunostomy. On the 9th postoperative day, the patient developed a high output anastomotic bile leak that required a redo of the cholangiojejunostomy. The postoperative period was marked by a surgical incision site of incomplete evisceration that was managed non-operatively by negative wound pressure. The follow-up was optimal, with no complications at 55 mo. CONCLUSION: In conclusion, the current case clearly supports that a favorable outcome in severe liver trauma with associated vascular and biliary injuries is achieved thru proper therapeutic management, conducted in a tertiary referral hepato-bilio-pancreatic center, where a stepwise and complex surgical approach is mandatory.

Surgical treatment for severe liver injuries: a single-center experience.

BACKGROUND: The liver is one of the most frequently injured organs in abdominal trauma. The advancements in diagnosis and interventional therapy shifted the management of liver trauma towards a non-operative management (NOM). Nevertheless, in severe liver injuries (LI), surgical treatment often involving liver resection (LR) and rarely liver transplantation (LT) remains the main option. The present paper analyses a single center experience in a referral HPB center on a series of patients with high-grade liver trauma. METHODS: Forty-five patients with severe LI, that benefitted from NOM (6 pts), LRs (38 pts), and LT (1 pt) performed in our center between June 2000 and June 2019, were included in a combined prospective and retrospective study. The median age of the patients was 29 years (median 33, range 10-76), and the male/female ratio of 33/12. Almost all cases had blunt trauma, except 2 with stab wound (4.4%). RESULTS: LIs classified according to the American Association for the Surgery of Trauma (AAST) system were 13.3% (grade III), 44.2% (grade IV), and 42.2% (grade V); none were grade I, II or VI. The rate of major LR was 56.4% (22 LRs). The median operative time was 200 minutes (mean 236; range 150-420). The median blood loss was 750 ml (mean 940; range 500-6500). Overall and major complication rates were 100% (45 pts) and 33.3% (15 pts), respectively. Overall mortality rate was 15.6% (7 pts). CONCLUSIONS: Severe liver trauma, often involving complex liver resections, should be managed in a referral HPB center, thus obtaining the best results in terms of morbidity and mortality.
