AIM: Duplication of the gallbladder is a very rare congenital variant, showing an incidence of about 1 in 4000 in the population, occurring twice as often in women than in men. In the literature only a few cases of prenatal diagnosis are reported. The knowledge of the existence of this anatomical variable is very important in order to avoid complications and iatrogenic damage during interventional and surgical procedures involving the biliary tract or adjacent organs.

CASE REPORT: A 79-year-old patient was admitted to our Hospital in May 2021 presenting abdominal pain. During hospitalization, a 5cm adenocarcinoma of the ascending colon was found. During surgery the known accessory gallbladder was found strongly adhering to the proximal transverse colon. The challenging viscerolysis maneuvers caused a lesion on one of the gallbladders, so we decided to proceed with cholecystectomy of both gallbladders.

RESULTS AND DISCUSSION: Duplication of the gallbladder is a rare congenital anatomical variant and requires special attention to the biliary and arterial anatomy in order to avoid iatrogenic damage. This variant can complicate surgical treatment for complications that need urgent treatment, such as cholecystitis. Currently the technique of choice for the evaluation of the biliary tree is magnetic resonance cholangiography. Laparoscopic cholecystectomy is the treatment of choice.

CONCLUSION: Surgeons should be aware of the different forms of presentation of gallbladder pathologies, also the ones that are not “the standard” of routine. Detailed preoperative study is essential to avoid a missed diagnosis
