Agenesis of the gallbladder is rare. Three groups have been identified: the
se with multiple fetal anomalies, asymptomatic cases, and symptomatic cases
. Right upper quadrant pain is present in 90% of the cases, nausea and vomi
ting in 60%, and jaundice in 35%, Operative strategy is aimed at thorough e
xploration to locate an aberrant gallbladder, We treated a 72-year-old woma
n with right upper quadrant pain, nausea, and vomiting but no fever or jaun
dice. Physical examination revealed right upper quadrant tenderness without
rebound. The white blood cell count was 10,300/mm(3), Total bilirubin leve
l was 1.6 mg/dL. Ultrasonography revealed one gallstone and an enlarged com
mon bile duct. Laparoscopic cholecystectomy was converted to open technique
after failure to locate the gallbladder, On intraoperative cholangiogram,
no gallbladder was identified. A T-tube was placed.
