Gallbladder perforation. An imaging analysis

Isolated traumatic gallbladder injury: A case report

BACKGROUND

Isolated gallbladder injury (GI) (IGI) directly induced by abdominal trauma is rare. Symptoms, indications, and imaging examinations of IGI are frequently non-specific, posing tremendous diagnostic challenges, which are simple to overlook and may have severe implications. Improving doctors' understanding of gallbladder injury (GI) facilitates early detection and decreases the likelihood of severe consequences, including death.

CASE SUMMARY

We report a case of IGI caused by blunt violence (after falling from three meters with the umbilicus as the stress point) and performed laparoscopic repair of the gallbladder rupture, which helps clinicians understand IGI and reduce the severe consequences of delayed diagnosis. Through extensive medical history and dynamic abdominal ultrasound evaluation, doctors can identify GI early and begin surgery, thereby decreasing the devastating repercussions of delayed diagnosis.

CONCLUSION

This article aims to improve clinicians' understanding of IGI and propose a method for the diagnosis and treatment of GI.

Acute cholecystitis, biliary obstruction, and biliary leakage

The use of cholescintigraphy to diagnose acute cholecystitis, biliary obstruction, and biliary leakage dates back to the late 1970s. Today, despite the many advances in imaging instrumentation, radiopharmaceuticals, and methodology over these years, cholescintigraphy still plays an important role in confirming or excluding these diagnoses in acutely ill patients. Acute calculous and acalculous cholecystitis, gallbladder perforation, biliary obstruction, and biliary leakage often present as acute abdominal pain, and must be differentiated from other surgical and nonsurgical etiologies with similar symptoms and presentation. Understanding the pathophysiology of acute hepatobiliary diseases is vital for deciding on the most advantageous imaging work-up and for interpretation of the studies. To optimize the value of cholescintigraphy, up-to-date methology, proper use of appropriate pharmacologic interventions, and recognition of characteristic image findings are critical.

Sonographic diagnosis of traumatic gallbladder rupture

Gallbladder injuries after blunt abdominal trauma are rare and often follow a vague and insidious clinical course. Consequently, gallbladder injuries commonly go undiagnosed until exploratory laparotomy. Early diagnosis is essential, because trauma to the gallbladder is typically treated surgically, and delay in treatment can result in considerable mortality and morbidity. With sonography emerging as a first-line modality for evaluation of intra-abdominal trauma, sonographers may wish to become more familiar with the appearance of gallbladder injury on sonography to facilitate earlier diagnosis and to improve treatment and prognosis. We report a case of gallbladder perforation after blunt abdominal trauma diagnosed on the basis of computed tomography (CT) and sonography.

Role of sonography in the diagnosis of gallbladder perforation

PURPOSE

Gallbladder perforation is a dreaded complication of acute cholecystitis that is associated with a high mortality rate. Early detection of gallbladder perforation reduces the associated mortality and morbidity rates. The purpose of this study was to highlight the role of sonography in the diagnosis of gallbladder perforation and to compare the diagnostic accuracy of sonography with that of CT.

METHODS

We retrospectively evaluated the sonographic and CT findings in surgically proven cases of gallbladder perforation.

RESULTS

In 18 of 23 cases, both sonography and CT had been performed; in the other 5 cases, only sonography had been performed. Sonography helped to diagnose the defect in the gallbladder wall and gallbladder perforation in 16 (70%) of 23 patients. In the 18 cases in which both sonography and CT had been performed, sonography showed the wall defect in 11 cases (61%), whereas CT was diagnostic in 14 cases (78%). The difference between sonography and CT in the ability to visualize a defect in the gallbladder wall was not statistically significant.

CONCLUSIONS

Sonography is useful for diagnosing gallbladder perforation and detecting the defect in the gallbladder wall. We believe that sonography should be the first-line imaging modality for evaluating the patients in these cases.

Septated Ascites and Cholelithiasis

Calculus disease in the gallbladder usually results in postprandial attacks of the right upper quadrant and epigastric pain that prompt early medical evaluation and treatment. When calculus biliary disease progresses to severe inflammation of the gall-bladder, it may progress to rupture and fistula formation. When rupture does occur, it is usually confined by an adjacent viscous to the right upper quadrant of the abdomen. The following case details a clinical course of advanced biliary disease with gallbladder rupture in an elderly patient whose reticence allowed the disease to progress to an advanced state.

Unusual presentation of perforation of the gallbladder

Perforation of the gallbladder is a known sequela of acalculus cholecystitis or trauma. A perforated gallbladder may be acute or chronic and can present with vague symptoms making the diagnosis difficult. With delayed recognition there is increased morbidity and mortality. The preoperative diagnosis requires an awareness of the symptoms and signs of acalculus cholecystitis as well as factors that predispose to the development of the diseased gallbladder. Awareness of the radiographic findings associated with a perforated gallbladder and acalculus cholecystitis is also important. The following is a case report of a child with a perforated gallbladder with a radiographic presentation not previously described. A review of the clinical pathogenesis and reported radiographic findings is also included.
