Gallbladder volvulus with gangrenous cholecystitis - A case report.

Introduction and Importance: Gallbladder torsion (volvulus) is a very rare pathology that occurs when the gallbladder rotates on the cystic duct/cystic artery axis, resulting in blockage of bile drainage and blood flow.
Case Presentation: We present the case of an elderly 87-year-old female who experienced acute gallbladder torsion. The patient presented with acute left chest pain that radiated to the patient's back and nausea but no emesis. A thorough physical examination, serologic studies, abdominal ultrasound, and computed tomography scan revealed gallbladder dilation, a thickened wall, enlarged common bile duct (approximately 1 cm), and the presence of pericholecystic fluid, all of which were consistent with acute cholecystitis. Laparoscopic cholecystectomy led to an intraoperative diagnosis of completely gangrenous gallbladder volvulus (GBV) with a 360-degree counter clockwise rotation. The pathology led to a final diagnosis of acute necrotizing cholecystitis without evidence of malignancy.
Clinical Discussion: GBV (gallbladder torsion) is typically observed in elderly patients at a female-to-male ratio of 4:1 and a median age at presentation of 77 years. Few advancements have been made in accurate diagnosis of GBV using clinical findings or the results of radiographic imaging, leading to accurate preoperative diagnoses in only 25 % of patients.
Conclusion: Though GBV usually presents with right upper quadrant pain, our patient had the rare presentation of left sided chest pain mimicking acute coronary syndrome. GBV is an uncommon condition that occurs frequently in the elderly, particularly in women. Accurate preoperative diagnosis remains daunting, since clinical, laboratory, and radiographic findings often lead to an incorrect diagnosis of acute cholecystitis. Prompt diagnosis necessitates a high level of suspicion, and laparoscopic cholecystectomy is the recommended treatment/management.
