Gallbladder agenesis

Gallbladder agenesis: An accidental finding during laparotomy for hepatic tumor

BACKGROUND

Anomalies of the biliary system are frequently encountered. Agenesis of the gall bladder is a rare. The exact incidence is not known as most cases are asymptomatic and diagnosed incidentally during surgeries for unrelated conditions or at autopsy. This anomaly may occur alone or in association with other anomalies such as other biliary anomalies, portal vein anomalies and other vascular anomalies, or in some cases hepatic, gastrointestinal or anomalies in other body systems.

CASE PRESENTATION

An elderly man diagnoses with segment VI liver tumor and planned for surgical resection. During surgery we accidentally discovered gall bladder agenesis with slightly dilated common bile duct. The tumor resected successfully and the final diagnosis was well differentiated with hepatocellular carcinoma.

CONCLUSION

Careful search for the gall bladder must be done before diagnosing agenesis of the gall bladder. No conversion is required provided adequate visualization and search for the gall bladder is done during laparoscopy. Postoperative MCRP will define the biliary anatomy and to help the surgeons to have postoperative accurate decision.

Successful liver transplantation using a whole liver graft with gallbladder agenesis: First report in pediatric liver transplantation

INTRODUCTION

Gallbladder agenesis (GA) is a rare congenital condition, occurring in approximately 40/100.000. It is likely due to an embryologic mishap in the development of the gallbladder bud and can be associated with other congenital variations in biliary anatomy. However, the liver likely suffers no functional impairment and can be safely used for transplantation. To the best of our knowledge, this is the first case report describing a pediatric liver transplantation (PLT) using a graft with GA.

CASE REPORT

A 10-year-old boy with methylmalonic aciduria underwent isolated liver transplant with a deceased graft from a donor with no relevant medical or surgical history and normal laboratory tests. During the back-table liver preparation procedure, no evidence of gallbladder was found, raising the possibility of a GA, confirmed by intraoperative cholangiography. The liver transplantation procedure was uneventful despite the particularly rare combination of biliary tree anatomic distribution found in the cholangiography. At 1 year of follow-up, there were no clinical, laboratory, or imagological signs of bile leaks or anastomotic site stricture.

DISCUSSION

The present report highlights the importance of the accurate knowledge of the vasculobiliary anatomic variation, particularly in extremely rare cases, such as GA, and in complex hepatobiliary procedures, such as PLT. In our opinion, grafts with GA should not be discarded for transplantation.

Gallbladder agenesis: A case report and review of the literature

•

Gallbladder agenesis presented with symptoms similar to biliary colic can be diagnosed without the need for surgical intervention.

•

MRCP is considered a test of choice for diagnosis of gallbladder agenesis.

•

If gallbladder agenesis is discovered during laparoscopy no conversion to laparotomy is needed.

Introduction

Gallbladder agenesis is a rare congenital abnormality with an incidence of 10–65 per 100,000. Approximately half of these patients are surgically operated on because of the symptoms similar to biliary colic, and correct diagnosis is established intra-operatively.

We present a clinical case of gallbladder agenesis from our practice.

Presentation of case

A 49 (forty-nine) - year- old women was admitted in the Emergency Department of our clinic. Symptoms were similar to the biliary colic. Ultrasonography showed hyperechogenic acoustic shadow on the projection of the gallbladder which was considered as constricted gallbladder and cholecystolithiasis was diagnosed. Laparoscopic cholecystectomy was considered. During laparoscopy gallbladder could not be found. Surgical operation was completed without conversion. Postoperative treatment included analgesics and antispasmodics. Pre-operative symptoms disappeared. One month later magnetic resonance cholangiopancreatography (MRCP) confirmed gallbladder agenesis diagnosis. Health condition of the patient is satisfactory, without any complications after a year of surgery.

Discussion

Gallbladder agenesis presented with symptoms similar to biliary colic can be diagnosed without surgical intervention. Conservative treatment consists of antispasmodic drugs.

Conclusion

If the shrunken gallbladder is detected on the ultrasound, additional radiological examinations are required. MRCP is considered as a test of choice among the radiological investigations. If gallbladder agenesis is identified on laparoscopy, there is no need for further conversion. For postoperative follow up examination MRCP investigation is recommended.

Gallbladder agenesis mimicking cholelithiasis in an adult

We present the case of a 24-year-old woman with morbid obesity who came to the emergency department with right upper quadrant abdominal pain associated with nausea and vomiting. Her workup included a right upper quadrant ultrasound suggestive of a small gallbladder with cholelithiasis without sonographic evidence of acute cholecystitis. She underwent attempted laparoscopic cholecystectomy with no identifiable gallbladder during surgery. Postsurgical cross-sectional imaging confirmed gallbladder agenesis. This case provides an example of a rare but convincing clinical and radiologic mimic of cholelithiasis. In certain cases of biliary colic and imaging revealing a small gallbladder, a magnetic resonance cholangiopancreatography may be warranted to evaluate gallbladder agenesis and avoid unnecessary surgery.
