Diagnosis of isolated perforation of the gallbladder following blunt trauma using sonography and CT scan

Complete Transection of the Cystic Duct and Artery after Blunt Trauma: A Case Report

Extrahepatic biliary tract and gallbladder injuries following blunt abdominal trauma are uncommon. Traumatic cystic duct transection is even rarer, which has frequently caused missed diagnosis and delayed treatment. An 18-year-old female patient with no past medical history was transferred to the Trauma Center of Kyungpook National University Hospital after falling from a height of approximately 20 meters. She became hemodynamically stable after initial resuscitation, and initial contrast-enhanced abdominal computed tomography (CT) showed right kidney traumatic infarction and multiple intrahepatic contusions with minimal fluid collection but no extravasation of the contrast. She was admitted to the intensive care unit. On the second day of hospitalization, her abdomen became distended, with follow-up CT showing a large collection of intra-abdominal fluid. Laparoscopic exploration was then performed, which revealed devascularization of the gallbladder with complete transection of the cystic duct and artery. Laparoscopic cholecystectomy was performed, as well as primary closure of the cystic duct orifice on the common bile duct using a 4-0 Prolene suture. After surgery, no clinical evidence of biliary leakage or common bile duct stricture was observed.

Isolated Gallbladder Injury after Blunt Abdominal Trauma: a Case Report and Review

We describe a case of isolated gallbladder contusion after deceleration trauma. On admission, no evident signs of intra-abdominal injury were present. However, after 24 h observation an explorative laparotomy was performed because of persistent abdominal complaints. A contusion of the gallbladder wall was found with intraluminal haematoma and a cholecystectomy was performed. Isolated injury of the gallbladder after blunt trauma is extremely rare. Risk factors are distention of the gallbladder, deceleration trauma and the presence of a relatively mobile gallbladder. Clinical signs often are very subtle. Delayed presentation is common with signs of hemobilia or obstruction due to intraluminal clots. Ultrasound and computed tomography are suitable diagnostic tools. However, the diagnosis is often missed if no other injuries are present. Signs pointing to gallbladder injury are a collapsed gallbladder with pericholecystic fluid or a hydroptic gallbladder with intraluminal hematoma. Hepatobiliary scintigraphy or angiography might be necessary if additional injuries are suspected. The choice of treatment depends on the kind of injury. Contusion of the gallbladder allows conservative treatment, but in case of a rupture, surgery will be necessary. Accompanying bile duct injuries can be treated by endoscopic stenting. If active arterial bleeding is present, selective embolization can be performed.

Blunt trauma of the pancreas and biliary tract: a multimodality imaging approach to diagnosis

Injuries of the pancreas, gallbladder, and bile ducts due to blunt trauma are relatively uncommon and difficult to detect but are associated with high morbidity and mortality, especially if diagnosis is delayed. Accurate and early diagnosis is imperative, and imaging plays a key role in detection. Knowledge of the mechanisms of injury, the types of injuries, and the roles of various imaging modalities is essential for prompt and accurate diagnosis. Early recognition of disruption of the main pancreatic duct is important because such disruption is the principal cause of delayed complications. Computed tomography (CT) can demonstrate pancreatic parenchymal injuries and complications such as abscess, fistula, pancreatitis, and pseudocyst. CT findings can also suggest disruption of the pancreatic duct; however, the ability of CT to indicate this finding depends on the degree of parenchymal injury. Magnetic resonance (MR) cholangiopancreatography allows direct imaging of the pancreatic duct and sites of disruption. Gallbladder injuries can be detected with CT, ultrasonography, hepatobiliary scintigraphy, or MR cholangiopancreatography. CT findings include a collapsed gallbladder, wall thickening, inhomogeneous mural enhancement, and pericholecystic fluid. Bile duct injuries can be suggested with CT, which may show ascites and associated liver injuries, and can be confirmed with hepatobiliary scintigraphy.

Laparoscopic treatment of an isolated gallbladder rupture following blunt abdominal trauma in a schoolboy rugby player

Laparoscopic treatment of an isolated gallbladder rupture in a schoolboy rugby player resulting from blunt abdominal trauma has not previously been reported. A case report of this rare occurrence is presented together with a brief review of the literature.
