Dropped Gallstones Causing Transdiaphragmatic Migration and Thoracic Empyema

Pleural empyema caused by dropped gallstones after laparoscopic cholecystectomy for acute cholecystitis: a case report

BACKGROUND

Dropped gallstones during laparoscopic cholecystectomy (LC) sometimes induce postoperative infectious complications. However, pleural empyema rarely occurs as a complication of LC.

CASE PRESENTATION

We present the case of a 66-year-old woman with right pleural empyema. She previously underwent LC for acute gangrenous cholecystitis 11 months ago. The operative report revealed iatrogenic gallbladder perforation and stone spillage. The bacterial culture of the gallbladder bile was positive for Escherichia coli. Chest and abdominal computed tomography revealed right pleural effusion, perihepatic fluid collection, and multiple small radiopaque density masses. Although ultrasound-guided transthoracic drainage was performed, the drainage was incomplete, and systemic inflammatory reaction persisted. Consequently, thoracotomy and laparotomy with gallstone retrieval were performed, and the patient recovered completely. The patient has remained well without complications after 14 months of follow-up.

CONCLUSIONS

We report a rare case of pleural empyema caused by dropped gallstones after LC. This case emphasized the importance of completely retrieving the dropped gallstones to prevent late infectious complications after LC.

Routes of Transdiaphragmatic Migration from the Abdomen to the Chest

The diaphragm serves as an anatomic border between the abdominal and thoracic cavities. Pathologic conditions traversing the diaphragm are often incompletely described and may be overlooked, resulting in diagnostic delays. Several routes allow abdominal contents or pathologic processes to spread into the thorax, including along normal transphrenic structures, through congenital defects in the diaphragm, through inherent areas of weakness between muscle groups, or by pathways created by tissue destruction, trauma, or iatrogenic injuries. A thorough knowledge of the anatomy of the diaphragm can inform an accurate differential diagnosis. Often, intraperitoneal pathologic conditions crossing the diaphragm may be overlooked if axial imaging is the only approach to this complex region because of the horizontal orientation of much of the diaphragm. Multiplanar capabilities of volumetric CT and MRI provide insight into the pathways where pathologic conditions may traverse this border. Knowledge of these characteristic routes and use of multiplanar imaging are critical for depiction of specific transdiaphragmatic pathologic conditions.^©RSNA, 2020.

Consequences of Lost Gallstones During Laparoscopic Cholecystectomy: A Review Article

BACKGROUND

Laparoscopic cholecystectomy (LC) has become a popular and widespread procedure for the treatment of gallstone disease. There is still an increasing concern about specific complications of LC due to gallbladder perforation and spillage of bile and stones. Although unretrieved intraperitoneal gallstones rarely become symptomatic, their infective complications may cause serious morbidities even after a long interval from LC.

METHODS

We performed a review of the literature on the diagnosis, prevention, consequences, and management of lost gallstones. All studies with a focus on lost gallstones or perforated gallbladder were analyzed to evaluate the postoperative complications.

RESULTS

Between 1991 and 2015, >250 cases of postoperative complications of spilled gallstones were reviewed in the surgical literature. The most common complications are intraperitoneal abscesses and fistulas. Confusing clinical pictures due to gallstones spreading in different locations makes diagnosis challenging. Even asymptomatic dropped gallstones may masquerade intraperitoneal neoplastic lesions.

CONCLUSIONS

Every effort should be made to prevent gallbladder perforation; otherwise, they should be retrieved immediately during laparoscopy. In cases with multiple large spilled stones or infected bile, conversion to open surgery can be considered. Documentation in operative notes and awareness of patients about lost gallstones are mandatory to early recognition and treatment of any complications.

A case of persistent hiccup after laparoscopic cholecystectomy

A 79-year-old man, with history of recent laparoscopic cholecystectomy, came to our attention for persistent hiccup, dysphonia, and dysphagia. Noninvasive imaging studies showed a nodular lesion in the right hepatic lobe with transdiaphragmatic infiltration and increased tracer uptake on positron emission tomography. Suspecting a malignant lesion and given the difficulty of performing a percutaneous transthoracic biopsy, the patient underwent surgery. Histological analysis of surgical specimen showed biliary gallstones surrounded by exudative inflammation, resulting from gallbladder rupture and gallstones spillage as a complication of the previous surgical intervention. This case highlights the importance of considering such rare complication after laparoscopic cholecystectomy.

Thoracic empyema after laparoscopic cholecystectomy: an unusual cause

Thoracic empyema after laparoscopic cholecystectomy is a rare complication. It is associated with dropped gallstones during the operation. In this case, we report a hepatocellular adenoma hemorrhage underneath an old diaphragm rupture, causing empyema after laparoscopic cholecystectomy.

Video-assisted Thoracoscopic Surgery (VATS) drainage of salmonella enteritidis empyema and needle-localization for retrieval of a dropped gallstone

INTRODUCTION

Spillage of gallstones into the peritoneal cavity (dropped gallstones) is more common in laparoscopic compared with open cholecystectomy. Subsequent infectious complications are often delayed, occurring in 0.1% to 2.9% of cases. We present the first reported case of Salmonella enterica subphrenic abscess and empyema complicating dropped gallstones, treated with video-assisted thoracoscopic surgery (VATS), and surgical retrieval.

CASE REPORT

A 67-year-old male with symptomatic cholelithiasis underwent an uncomplicated laparoscopic cholecystectomy. Four years later, he presented with a mass in his right flank, and an abdominal computed tomography (CT) revealed a right flank intramuscular abscess containing gallstones. The abscess was drained surgically with removal of gallstones. He was readmitted 15 months later with right upper quadrant pain, fever, and dyspnea. Chest and abdominal computer tomography (CT) showed a right pleural effusion and a right subphrenic abscess containing a dropped gallstone. The gallstone was localized with a needle using CT guidance. He subsequently underwent a right VATS for decortication. A separate flank incision was made at the site of the needle to drain the subphrenic abscess and retrieve the gallstone. Cultures from his empyema grew S enteritidis. The patient made an uneventful recovery.

DISCUSSION

During laparoscopic cholecystectomy, efforts should be made to retrieve dropped gallstones as they can cause abscess and empyema, which might necessitate furthermore surgical intervention. The use of VATS has been established as a safe and effective alternative to thoracotomy, including the treatment of empyema. Needle-localization resulted in a successful retrieval of the gallstone in our patient. Culture of the abscess is important, as unusual organisms such as Salmonella could be present. S. enteritidis has not been implicated as a cause of cholecystitis and is rarely associated with abdominal abscesses. We postulate that the organism reached the gallbladder through the bile or bloodstream after gastrointestinal colonization and that its persistence in the gallbladder may have been facilitated by gallstones.
