Gallbladder

Gallbladder

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

Cholecystitis

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Diseases of the Liver and Gallbladder

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Appendicitis-II: Diagnostic Studies and Management

Appendicitis-II: Diagnostic Studies and Management

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Summary

Duplicate gallbladder is a rare congenital anomaly. A case of duplicated gallbladder and cystic duct in a 15-year-old girl led to a proposed Unified Classification of Multiple Gallbladders.

Area of Science:

Embryology
Surgical Anatomy
Gastroenterology

Background:

Duplicate gallbladder is a rare congenital anomaly, with ~210 cases reported.
Embryonic development abnormalities during weeks 5-6 of gestation cause these variations.
Existing classifications include duplicate, triplicate, and septated gallbladders.

Observation:

A 15-year-old female presented with a duplicated gallbladder and a duplicated cystic duct.
This rare combination of anomalies was identified.
The patient underwent successful laparoscopic cholecystectomy.

Findings:

The case highlights an extremely unusual combination of gallbladder and cystic duct duplication.
A review of existing literature was conducted.
The Unified Classification of Multiple Gallbladders is proposed based on these findings.

Implications:

The proposed classification may aid in standardizing the description of gallbladder anomalies.
Understanding these rare variations is crucial for surgical planning and patient outcomes.
This case contributes to the knowledge base of congenital gallbladder malformations.
