Complete laparoscopic cholecystectomy for a duplicated gallbladder: A case report.

Abstract：

INTRODUCTION:Duplication of the gallbladder (GB) is a rare congenital abnormality occurring in 1 in 4000 to 5000 births. Three types have been reported: type I (split primordial GB), type II (2 separate GBs with their own cystic ducts), and type III (triple GBs drained by 1 to 3 separate cystic ducts). Patients with a duplicated GB are usually asymptomatic and are sometimes not diagnosed on preoperative imaging, which might increase the difficulty and risk of cholecystectomy. The key to successful treatment is total removal of the duplicated GB to avoid the recurrence of disease. Intraoperative cholangiography is recommended for identifying and resecting duplicated GBs. The final diagnosis depends on the histopathology. PATIENT CONCERNS:A 62-year-old woman had recurrent upper abdominal pain and nausea for 1 year, with no fever, jaundice, or other symptoms. An ultrasound of the abdomen indicated polyps in the GB. Computed tomography (CT) revealed moderate dense structures attached to the wall of the GB and an unusual 47 × 21 mm elliptical structure with an extra tubule located above the main GB. DIAGNOSIS:A diagnosis of duplicated GB was made based on the histopathology. INTERVENTIONS:The patient underwent a laparoscopic cholecystectomy with total removal of the duplicated GB. OUTCOMES:The patient's postoperative course was uneventful and she was discharged from the hospital on the second postoperative day. She had no upper abdominal pain at the 6-month follow-up. CONCLUSION:Duplicated gallbladder is a rare congenital biliary anatomy, which is usually asymptomatic and sometimes cannot be diagnosed on preoperative imaging. With gallbladder disease, the duplicated GBs should be removed totally; a laparoscopic approach should be attempted first and cholangiography is recommended to aid in identifying and resecting the duplicated GBs. The final diagnosis depends on the histopathology. There is still insufficient evidence on the need to remove duplicated GBs found incidentally.
