Short title: Gallbladder Torsion

Gallbladder torsion is a rare cause of abdominal pain; however, it is important to diagnose pre-operatively. We report two cases of gallbladder torsion, both of which were not recognized until the time of surgery. Both patients were elderly thin females, presenting with right upper quadrant pain, and on examination had a positive Murphy’s sign, and pre-operative imaging was suggestive of acalculus cholecystitis. One patient was initially managed by percutaneous insertion of a cholecystostomy tube, with progression to a laparoscopic cholecystectomy after a failure of resolution of symptoms. The second patient was taken to theater shortly after presentation, with the gallbladder torsion recognized intra-operatively. In both cases, the gallbladder was distorted and a routine laparoscopic cholecystectomy was performed with good recovery following. These two cases highlight the need for gallbladder torsion to be considered as a diagnostic possibility in those presenting with right upper quadrant pain, particularly those groups at most risk, including elderly thin females. Whilst other causes of cholecystitis can be managed non-operatively, at least in the acute phase, gallbladder torsion requires urgent operative intervention.

Gallbladder torsion is rare and occurs secondary to the twisting of the gallbladder on its mesentery. Less than 350 cases of gallbladder torsion have been reported, with the diagnosis of many of these cases only occurring at the time of operation [1]. Anatomical variation is thought to play a role in its pathogenesis, with an abnormally long mesentery joining the gallbladder to the liver, resulting in a free-hanging or “floating gallbladder”, which was first described by Wendel in 1898 [2]. This gives the gallbladder the mobility required to twist, resulting in torsion [3]. It is theorized that loss of visceral fat and associated shrinkage of the liver result in a gallbladder that hangs free by its mesentery [4]. It is then not suprising that gallbladder torsion has been most frequently observed in elderly thin females [1].

Whilst the vast majority of cases of gallbladder torsion are diagnosed intra-operatively, there are a small number of case reports which report on pre-operative diagnosis via the use of magnetic resonance cholangiopancreatography and computed tomography (CT) [5, 6].

Whilst other causes of cholecystitis can be treated non-operatively, gallbladder torsion requires urgent surgical intervention, because of the risk of ischemia and gangrene leading to perforation, and as such there is a need to increase its pre-operative diagnosis.

Case Reports▴Top 

Case 1

An 84-year-old female presented to the emergency department with a 2-day history of right upper quadrant abdominal pain. She had a background of severe chronic obstructive pulmonary disease. Her abdominal examination revealed a tender right upper quadrant with a positive Murphy’s sign. Her laboratory results were largely unremarkable with a non-elevated white cell count, a normal bilirubin and liver function tests, excepting a mildly elevated gamma-glutamyl transpeptidase (GGT) and aspartate aminotransferase (AST) (60 U/L (reference (ref) 5 - 50 U/L) and 133 U/L (ref 30 - 110 U/L)). An abdominal CT showed a markedly distended gallbladder extending to the right iliac fossa and mild thickening of the gallbladder wall. An ultrasound revealed gallbladder distension with heterogeneous gallbladder wall thickening up to 15 mm without evidence of gallstones. A diagnosis of acalculous cholecystitis was made, and the patient proceeded to have percutaneous cholecystostomy in light of the gallbladder distension and the patient’s comorbidities. The patient failed to improve symptomatically and 8 days later underwent laparoscopy which identified a torsion of the gallbladder. She underwent a laparoscopic cholecystectomy and recovered well and was discharged on day 4 post-operatively.

Case 2

The second case is an 81-year-old female, who presented to the emergency department after a 1-day history of right upper quadrant pain. She also had right upper quadrant tenderness with a positive Murphy’s sign. She had a markedly elevated neutrophilia at 26.5 × 109/L. Her liver function tests were largely unremarkable (bilirubin 12 µmol/L (normal < 20 µmol/L), GGT 93 U/L (ref 5 - 50 U/L), alkaline phosphatase (ALP) 105 U/L (ref 30 - 110 U/L), alamine aminotransferase (ALT) 30 U/L (ref 10 - 50 U/L) and AST 37 U/L (ref 10 - 35 U/L)). An ultrasound revealed a thickened gallbladder wall up to 9 mm, direct tenderness with probe pressure and no evidence of gallstones. The patient was diagnosed with acalculous cholecystitis. This patient was taken to theater for laparoscopy with intra-operative findings of a gallbladder torsion. The gallbladder was dark and congested without evidence of perforation. The gallbladder was distorted and routine laparoscopic cholecystectomy was performed. Histopathological examination of the gallbladder showed a necrotic wall and features suggestive of acute-on-chronic cholecystitis. She recovered well and was discharged on day 3 after the procedure.


The most common cause of cholecystitis is gallstone disease, caused by transient or permanent obstruction of the cystic duct [7]. Acalculous cholecystitis on the other hand is most often seen in critically ill patients in the intensive care unit and represents somewhere in the vicinity of 2-15% of cases of cholecystitis [8, 9]. Gallbladder torsion is a separate entity which can mimic other causes of cholecystitis. Pre-operative diagnosis is important as it requires urgent surgical management. The potential consequence of delaying intervention is ischemia with necrosis and perforation.

Whilst early cholecystectomy is recommended for the treatment of acute calculous cholecsytitis, initial non-operative treatment with delayed cholecystectomy has an adequate success rate, with this path more appropriate for some patient populations, dependent on their risk profile [10-12]. In addition, acalculous cholecystitis is often managed non-operatively with a growing trend towards percutaneous cholecystostomy as the initial and sometimes definitive management [13, 14]. In contrast, non-operative management with intravenous antibiotics and percutaneous cholecystostomy, as evidenced by this case study, are not viable management options in the treatment of gallbladder torsion, as it is not primarily an infective process and a percutaneous cholecystostomy does not correct the underlying pathology.

Pre-operative diagnosis remains difficult with presenting symptomatology and pre-operative investigation is similar to alternative causes of cholecystitis.

One case report reports a magnetic resonance imaging (MRI) showing an abnormal gallbladder position, with the fundus lying inferomedial to Hartmann’s pouch; however, this finding is not elsewhere reported in the literature [15]. Other studies report a “cystic duct knot sign” on ultrasonography and a CT finding of a “whirl sign” in cases of reported cases of gallbladder torsion [16, 17].

Whilst causes of cholecystitis can be managed non-operatively, gallbladder torsion requires emergency surgery and as such requires prompt recognition. Perforation and peritonitis secondary to biliary contamination are known as complications of gallbladder torsion.


In conclusion, gallbladder torsion should be considered in all cases of acalculus cholecystitis, particularly in elderly thin females. Gallbladder torsion requires operative management, and cannot be treated with a cholecystostomy, so pre-operative diagnosis is important.
