Supernumerary gallbladder

Last edited: 4/16/2026

Overview

Supernumerary gallbladder, also known as accessory gallbladder, refers to an extra gallbladder-like structure present alongside the main gallbladder, often asymptomatic but can present with biliary symptoms or complications 1.

Diagnosis

  • Imaging (US, CT, MRI) essential for identification and differentiation from other cystic structures 1.
  • Endoscopic ultrasound (EUS) may provide detailed visualization and characterization 1.
  • Histopathological confirmation via biopsy if surgical intervention is planned 1.

    • Management

  • Surgical excision is often recommended for symptomatic cases or when complications arise 1.
  • Conservative management may be considered for asymptomatic cases 1.
  • No specific pharmacological treatments are indicated; symptomatic relief for complications may involve supportive care 1.

    • Special Populations

  • Pregnancy: Limited data; surgical intervention should be individualized based on symptom severity and gestational age 1.
  • Pediatrics: Asymptomatic cases typically managed conservatively; symptomatic cases may require surgical intervention 1.
  • Elderly: Surgical risks should be carefully weighed; conservative management may be preferred in low-risk, asymptomatic patients 1.
  • Comorbidities: Presence of comorbidities may influence surgical approach and risk stratification 1.

    • Key Recommendations

  • Imaging studies (US, CT, MRI) are crucial for diagnosing supernumerary gallbladder (Evidence: Moderate 1).
  • Surgical excision is recommended for symptomatic supernumerary gallbladder (Evidence: Moderate 1).
  • Conservative management is appropriate for asymptomatic cases (Evidence: Expert opinion 1).
