Gallbladder Mucocele: Two Case Reports

ABSTRACT

Gallbladder mucocele (GBM) is the development of a swollen gallbladder caused by the accumulating of semisolid immobile mucoid material in the gallbladder fundus for functional or mechanical reasons. This is also called gallbladder hydrops. Its incidence is about 3%. Decreased bile flow, decreased gallbladder movement, and altered water absorption in the gallbladder lumen cause biliary sludge and thus predispose to the development of mucocele. The first case was a 26-year-old female patient who presented to the clinic with complaints of nausea, vomiting, flatulence, indigestion and pain in the epigastric region and the right-upper quadrant. On abdominal USG, it was determined that the gallbladder wall was normal and there were stones and sludge with a diameter of 14 mm in the gallbladder lumen. The second case was of a 34-year-old female patient who applied to the clinic with complaints of stomach pain and nausea. The patient was taken to the operation without performing USG in the second case. Laparoscopic cholecystectomy was performed in both cases, and histopathological examination revealed mucoid material in the lumen, flattened epithelium, and inflammatory cell infiltration in the focal areas. The diagnosis of ‘Gallbladder Mucocele’ was given to the patients accompanied by these findings. In this article, is discussed the clinicopathological results of two cases diagnosed with gallbladder mucocele together with the literature.
