Isolated Gallbladder Injury Secondary to Blunt Abdominal Trauma

Abstract

A 60-year-old male was admitted to our major level 1 trauma centre following a fall from the fourth storey of a car park and landing initially on his feet on concrete. The primary survey was unremarkable apart from abdominal pain and localised peritonism in the right upper quadrant and lower lumbar midline pain. The secondary survey revealed bilateral complex calcaneal fractures, multiple vertebral fractures and sternal fracture. A trauma CT scan showed pericholecystic fluid and described by the radiology team either as cholecystitis picture or possible disruption of the gallbladder wall. Based on the patient's stable presentation, the decision was made for a diagnostic laparoscopy to explore possible gallbladder injury and other concomitant injuries. Operative findings showed free bile in the right upper quadrant and right paracolic gutter and small amount of blood. The gallbladder did not have an obvious site of perforation but had a necrotic appearance. No further injuries identified laparoscopically after checking small and large bowel, and since no obvious perforation was identified, the decision was made to convert to laparotomy and duodenal exploration. On laparotomy, there was no evidence of duodenal or pancreatic injury on Kocher's manoeuvre and ligament of Trietz mobilisation. The gall bladder wall was stained and leaking bile, therefore a standard retrograde cholecystectomy was performed. No further intra-abdominal injuries were identified during the laparotomy. The patient made an unremarkable recovery. He was discharged home with physiotherapy for rehabilitation. We recommend a diagnostic laparoscopy and cholecystectomy for such injuries with a low threshold for duodenal exploration (Kocherization) if the perforation site is not obvious based on the high incidence of concomitant duodenal injuries.
