Some adults with porcelain gallbladder may be eligible to forgo prophylactic cholecystectomy, suggest the results of a single-center retrospective study.
Over 1.7 years of median follow-up (range, 0 to 12.7 years), the observational group had no detected gallbladder malignancies and 4% developed adverse events versus 13% in the prophylactic cholecystectomy group (P = .15), wrote Haley DesJardins and her associates at Tufts University, Boston. The report was published in the Journal of the American College of Surgery.
The findings “still raise concern about an association between gallbladder wall calcifications and gallbladder malignancies, and therefore still suggest the need for cholecystectomy in the young, healthy, or symptomatic patient,” the researchers wrote. Nonetheless, surveillance for patients “who are poor surgical candidates is a reasonable approach, with a low risk of malignancy over a limited time frame.”
The investigators suggest that surgeons consider intervention when symptoms and workup points to gallbladder malignancy. But consider avoiding prophylactic cholecystectomy in patients with “limited life expectancy and significant comorbidities,” they emphasized. “Based on the results of this study, the act of prophylactic cholecystectomy for every single patient with gallbladder wall calcifications seems obsolete.”
The study comprised 113 patients with porcelain gallbladder diagnosed between 2004 and 2016. Radiographic reviews identified 70 definite cases and 43 “highly probable” cases. In all, 90 patients started out with observation only, of whom 26% with abdominal pain did not have cholecystectomy because of “significant comorbidities.” Four patients (4.4%) in the observational group subsequently underwent cholecystectomy for biliary colic, as part of liver transplantation, or for prophylactic reasons. None developed complications. In all, 11% developed new gallstones on follow-up imaging and 8% showed progression from focal to diffuse porcelain bladder, the researchers said. None developed gallbladder malignancy during 1.7 years of median follow-up.
Histopathologies of the operative group identified two cases of gallbladder malignancy, of which one was detected on initial imaging. “This patient had a mass at the gallbladder infundibulum extending into the hepatic duct bifurcation,” the researchers explained. “It was not entirely evident whether the resected adenocarcinoma was originating from the gallbladder or from the bile duct. For the purpose of this study, this patient was listed as [having] gallbladder cancer.” The second case consisted of metastatic squamous cell gallbladder carcinoma.
The investigators concluded that “while it is seemingly very reasonable to observe asymptomatic patients with limited life expectancy and significant comorbidities, the decision to proceed with prophylactic cholecystectomy versus observation remains in the hands of the treating physician and patient; especially since absolute criteria or cut-offs cannot be defined at this point.”
No external funding sources were reported. The researchers reported having no conflicts of interest.
