Septate gallbladder: A rare congenital anomaly.

The septate gallbladder is a rare congenital malformation. It is considered a risk factor of complications after laparoscopic cholecystectomy. We are reporting an image in surgery of a septate gallbladder. It was discovered at an adult age. We are showing the difficulty of the diagnosis preoperatively on the radiological find.

CASE PRESENTATION

A 55‐year‐old man with no medical history complained about intermittent right upper quadrant abdominal pain. The physical examination and laboratory tests were normal.

Abdominal ultrasound showed a gallbladder with normal wall thickness and multiple gallstones associated with a saccular structure beside it.

A magnetic resonance cholangiopancreatography showed two gallbladders drained by a single cystic duct. (Figure 1).

The surgery was performed laparoscopically. Intraoperative findings showed the presence of a single‐bilobed gallbladder drained by a single cystic duct. Cholecystectomy was performed.

The examination of the specimen showed a transverse septum dividing the gallbladder into two compartments. (Figure 2).

Which diagnosis would you have determined?

1: accessory gallbladder

2: septate gallbladder

3: diverticulum of the gallbladder

4: extrahepatic choledochal cyst

The correct answer is 2.

Septate gallbladder is a congenital malformation, characterized by the presence of a septum that divides the gallbladder into two compartments. According to Boyden classification, there are two main types of congenital malformation, septate gallbladder and true duplication.

Septate gallbladder is usually asymptomatic.

It is fundamental to recognize the anatomical variation of the gallbladder to reduce the risk of iatrogenic bile duct injury during cholecystectomy. ,
