Three &#40;10&#46;7&#37;&#41; of 28 patients had a SRHA&#44; two of which were associated with intrahepatic hemorrhage and one with intraperitoneal bleeding&#46; Two patients were female and one was male&#46; The mean age was 41&#46;6 years old &#40;38 to 46 years old&#41;&#46; Sudden abdominal pain associated with hemodynamic instability occurred in all patients&#46; The female patients had a background history of oral contraceptive use&#46; Tumor markers including serum CA19-9&#44; alpha-fetoprotein and carcino-embryonic antigen were normal in all patients&#46; No chronic liver diseases were recorded in this series&#46; Liver function tests&#44;

The criteria for diagnosing hepatic adenoma was the presence of a hypervascular heterogeneous mass on CT scan with intratumoral necrosis or hemorrhage and the presence of a capsule or pseudo-capsule &#40;hypovascular area on CT&#41;

and due to hemodynamic instability all three patients underwent emergency surgery&#58; on two occasions by the emergency room surgeons&#46; and on one occasion by the hepatobiliary team&#46; The liver surgical team advice was always available at the institution and all cases were discussed with the consultant physician&#46; The anesthetic technique used was based on the principles of the acute hypovolemic patient&#44; and the volume of blood loss as well as blood infusion was based on physiological parameters in the operative room&#59; all solutions were warmed prior to infusion and administered via the rapid infusion system&#44; commercially known as Level 1 system&#46; A right subcostal incision was used extending to the left side &#40;the classical &#8220;mercedes&#8221; incision&#41;&#44; permitting full mobilization of the liver considering that in all cases the teams had a preoperative diagnosis of liver injury&#46; Once laparotomy was performed&#44; hemostasis or damage control was accomplished using absorptive gauzes and two opposing pressure vectors to compress the ruptured tissue between them&#46; Surgical procedures included intraoperative ultrasonography to assess the size and location of the tumor as well as the relationship between the lesion and vascular system&#46; The cases were handled using hepatic surgical techniques including vascular control of the portal pedicle and&#44; in one case&#44; control of the inferior vena cava close to the confluence of the hepatic vein&#46; None of the cases required temporary hepatic inflow occlusion &#40;Pringle maneuver&#41; or clamping of the IVC&#46;

CT permits an accurate diagnosis in typical cases of HA showing hyperdense mass with heterogeneous enhancement&#44;<a class="elsevierStyleCrossRefs" href="#bib23">23&#44;24</a> however typical features on CT were found in only 75&#37; of the cases&#46;<a class="elsevierStyleCrossRef" href="#bib23">23</a> We found SRHA to be a heterogeneous mass in all three patients&#44; however the patient with an intraperitoneal hemorrhage had a hypoattenuating image while the two patients with intrahepatic bleeding had hyperattenuating images&#44; corresponding to liver necrosis on the CT examination&#46; Hussain et al&#46;<a class="elsevierStyleCrossRef" href="#bib25">25</a> presented findings of HA on ultrasonography&#44; CT and MRI&#44; and correlating these findings with the pathological analysis&#46; It was noted that in the case of monophasic CT or when arterial phase is performed incorrectly&#44; HA can easily be misdiagnosed&#44; exposing patients to unnecessary delays in diagnosis and proper treatment&#46; It was noted that today&#44; MRI is a state-of-the-art imaging modality due to its ability to provide a more comprehensive and accurate work-up of focal and diffuse liver disease&#46; This is based on the unique properties of MR imaging&#59; it possess a combination of high intrinsic soft tissue contrast of the liver and liver lesions&#44; various distinctly different tissue characteristics for imaging and a high sensitivity for the presence or absence of contrast-uptake and enhancement patterns when using either non-specific or liver-specific contrast media&#46; Some patients with HA are discovered accidentally on routine physical examination or even during exploratory laparotomy for another indication&#46; These patients usually have totally asymptomatic liver masses and no laboratory evidence to suggest liver disease&#46; On the other hand&#44; fifty to sixty percent of patients with HA have intratumoral or intraperitoneal hemorrhages&#46;<a class="elsevierStyleCrossRefs" href="#bib25">25&#44;26</a> These patients are first seen with a sudden life-threatening intraabdominal hemorrhage&#46; Substantial mortality has been associated with delays in diagnosis of this condition&#59; mortality arises from hemorrhagic shock&#44; rapidly developing coagulopathies&#44; and postoperative complications&#46; Successfully treated patients had liver segmentectomies performed as an emergency procedure&#46; It is apparent that early diagnosis and operation are critical in this group&#46; Three patients in our series had ruptures&#59; two of them intrahepatically and one intraabdominally&#46; The former were treated with non-anatomic hepatic resection associated with right hepatectomy &#40;<a class="elsevierStyleCrossRef" href="#f3-cln64_8p775">Figure 3</a>&#41; and the latter with right extended hepatectomy&#46; The risk of HA bleeding increases with increased duration of oral contraceptive use and is related to the hormonal potency of the oral contraceptives used regardless of the duration of use&#46;<a class="elsevierStyleCrossRef" href="#bib27">27</a> The two female patients with intrahepatic bleeding were using hormonal contraceptives for at least three years&#46; Whether this use was the cause of their SRHA or not is a matter of speculation because we believe that many factors appear to be interrelated including&#58; &#40;1&#41; the woman&#8217;s age&#44; &#40;2&#41; the size of the tumor and &#40;3&#41; the potency of the oral contraceptive used&#46; Size of the hepatocellular adenoma is an established independent risk factor for malignancy&#46;<a class="elsevierStyleCrossRefs" href="#bib11">11&#44;13&#44;28</a> Surgical resection has been recommended for adenomas with an initial diameter of 5 cm or more in symptomatic patients&#44; even during pregnancy&#46;<a class="elsevierStyleCrossRefs" href="#bib6">6&#44;29</a> The resection of large adenomas has also been recommended because the risk of hemorrhaging is relatively high&#46; For smaller and asymptomatic adenomas&#44; an expectant approach is advocated&#46;<a class="elsevierStyleCrossRefs" href="#bib30">30&#44;31</a> The main surgical procedure for HA should be local or hepatic segmental resection in order to preserve the normal hepatic parenchyma since the tumor is benign&#46; In the emergency setting&#44; if the surgeon on call at the emergency room have the appropriate surgical skills to handle liver lesions&#44; the full procedure can be safely performed by them&#59; otherwise&#44; the lesion must be handled as in hepatic trauma&#44; with packing and damage control&#44; and after the initial approach the HPB team must be consulted for a definite surgical approach&#46; In the unlikely event of SRHA we recommend an anatomical-based resection of the liver or even non-anatomical resection depending upon the complexity of the intrahepatic or extrahepatic hemorrhage&#46; SRHA is a rare life-threatening condition&#46; In this series there were HAs larger than 10 cm&#46; Today&#44; it is well known that hepatocellular adenomas are only vascularized arterially&#46; This makes embolization safe and successful for stopping hemorrhages in acute settings&#46; In our cases&#44; the interventional radiology group was not yet available to perform the procedure and instead surgery was indicated&#46; Hurmann et al&#46;<a class="elsevierStyleCrossRef" href="#bib16">16</a> demonstrated that the ability of selective arterial embolization to induce necrosis of the tumor may indicate a role for this procedure in the management of either bleeding or non-bleeding adenomas with good results and lower complication rates when compared to surgery&#46;</p><p id="para70" class="elsevierStylePara elsevierViewall">In conclusion&#44; SRHA may necessitate emergency surgery for controlling hemorrhage and stabilizing the patient&#44; and the decision to operate depends both upon the patient&#8217;s condition and the expertise of the surgical team&#46;</p></span></span>"
