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 9^th 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.

Diagnosing Small for Gestational Age during second trimester routine screening: Early sonographic clues

OBJECTIVE

Small for gestational age (SGA) is generally defined as birth weight being at or below the 10th percentile. Children with SGA have a higher risk for complications. There is a need for early predictors, as the accurate diagnosis rate is only 50%. In the current study, we aimed to evaluate diagnostic performance of ultrasound (US)/color Doppler ultrasound (CDUS) parameters (umbilical vein-UV, right portal vein-RPV diameter/flow rate, and portal sinus-PS diameter) examined at 20-22 gestational week as SGA diagnostic factors.

MATERIALS AND METHODS

93 pregnant included (32 SGA, 61 controls). All the US examinations were performed between 20 and 22 weeks of gestation. UV, RPV, and PS measurements were performed by using the same image acquired for abdominal circumference measurement. A fetus with as estimated fetal weight (EFW) below the 10th percentile was diagnosed as SGA and SGA at birth was defined as having a birth weight under the 10th percentile.

RESULTS

Pregnant women in the SGA group were significantly older (30 ± 4.8 vs. 26.6 ± 5.4 years, p < 0.01). Median UV diameter was significantly lower in SGA group (2.20 vs. 2.40 mm, p = 0.001). Median RPV diameter was significantly lower in SGA group (2 vs. 2.10 mm, p = 0.018). Median PS diameter was significantly lower in SGA group (2 vs. 20.10 mm, p = 0.008).

CONCLUSION

UV, RPV, and PS diameters can be earlier predictors for SGA diagnosis. Routinely evaluation of these parameters during second trimester screening can increase SGA diagnosis rates and serve for early diagnose.
