Current evidence on the diagnosis and management of spilled gallstones after laparoscopic cholecystectomy.

BACKGROUND

Despite improvements in intraoperative and postoperative outcomes of laparoscopic cholecystectomy (LC), spilled gallstones (SGs) after LC remain a significant yet often overlooked complication, occurring in 1% to 40% of cases. This review discusses the most recent updates regarding the risk factors, presentations, complications, diagnosis, management, and prognosis of SGs after LC.

METHODS

A comprehensive systematic review was conducted using MEDLINE/PubMed, Google Scholar, Cochrane Library, and the Web of Science databases, with the range of search dates being between January 2015 and July 2024, regarding SG incidence, management, and complications.

RESULTS

Risk factors for SGs after LC include intraoperative gallbladder perforation because of poor operational environment, quantity, size, and type of stone (pigment, cholesterol rich, or mixed); presence of adhesions or anatomic variations; and insufficient surgical training. Of note, 60% of SG complications are abscesses from bacterial infections, which can progress to peritonitis, fistulas, lung/liver abscesses, and choledocholithiasis. SGs were associated with delayed presentation of unexpected clinical problems, with even diagnosis. Although treatment depends on the severity of the complication, when SGs are identified through imaging, often ultrasound and computed tomography, minimally invasive approaches and antibiotic courses are viable first-line approaches.

CONCLUSION

Although LC-associated spillage of gallstones is rare, the complications can be a serious cause of morbidity. Therefore, proper notification of operative complications, a high index of suspicion for patients with a previous history of LC, and awareness of appropriate diagnostic modalities are key variables for the early diagnosis and prevention of SG-related complications.
