Congenital Duplication of the Gallbladder

Duplication of the gallbladder is a rare congenital anomaly of the biliary system. In this article, two cases of gallbladder duplication are presented. The first case is a patient with double gallbladder and concomitant choledocholithiasis. The probable diagnosis of double gallbladder was made preoperatively by computed tomography. The patient underwent a successful open cholecystectomy and common bile duct exploration. In the second case, two cystic formations in the place of gallbladder are demonstrated with ultrasound scan in a woman with acute cholecystitis. At surgery, two gallbladders were found. A brief review of epidemiology and anatomy of double gallbladder is included, along with a discussion of the difficulties in diagnosis and treatment of this condition.

Double gallbladder with different disease entities: A case report

We report a rare case of gallbladder duplication in a young male patient with acute pyocoele in one vesicle and acute cholecystitis with cystadenoma in the other; another unusual feature was the absent or obliterated cystic duct in the proximal vesicle and non-communication with the second vesicle or the biliary system. Ultrasound examination had suggested a septate gallbladder; the diagnosis of dual gallbladder was made per-operatively during separation of the distal moiety which was presumed to be an adherent duodenum initially. Intraoperative cholecystogram confirmed the diagnosis and both gallbladders were removed successfully laparoscopically.A high degree of awareness, detailed preoperative investigations when anomalies are suspected and intraoperative cholangiography are necessary for accurate detailing of the biliary tree to avoid inadvertent damage to the biliary ductal system and overlooking of second or third gallbladder during surgery.

Unusual features of gall bladder duplication cyst with review of the literature

A 1-month-old female infant presented with a lump in the right hypochondrium extending into the right iliac fossa. Ultrasonography and computed tomography suggested an intestinal duplication cyst or a gall bladder cyst. Exploratory laparotomy revealed it to be a congenital gall bladder duplication cyst without associated complications. It was removed after confirming the presence of a normal gall bladder. The infant's postoperative course was uneventful. This unusual presentation of congenital gall bladder duplication cyst prompted us to report this case.

Double Gallbladder Diagnosed on Contrast-Enhanced MR Cholangiography with Mangafodipir Trisodium

uplication of the gallbladder is a rare anomaly of the biliary tract that may cause a medical or surgical problem if not diagnosed. MR cholangiography (MRC) has clearly shown capabilities for the diagnosis of biliary diseases [1]. We describe here a case of gallbladder duplication, visualized by MRC with mangafodipir trisodium, which has never been shown before, and we discuss the importance of this kind of imagery if double gallbladder is suspected.

Asymptomatic true gallbladder duplication: a case report and review of the literature

Gallbladder duplication is a rare event, with an incidence at autopsy of about 1/4000, with very few documented symptomatic cases reported. Preoperative diagnosis and differentiation of this malformation are important to prevent inadvertent damage to the biliary system, a complicated postoperative course, and repeat surgery. We present a case of true gallbladder duplication found incidentally during abdominal ultrasonography (US). The diagnosis was made with US and the Y-type duplication was demonstrated with magnetic resonance cholangiopancreatography (MRCP).

Heterotopic gastric mucosa in a duplicate gallbladder

A 7-year-old girl presented with recurrent acute pancreatitis. Detailed investigations, including endoscopic retrograde cholangiography, suggested a poorly defined biliary tract abnormality. At laparotomy, this was discovered to be a duplicate gallbladder each with a separate cystic duct but contained within a single serosal envelope. Both gallbladders were removed, and histologic examination found the inferior organ to be lined by heterotopic fundic-type gastric mucosa. Despite the absence of any remaining structural biliary abnormality and no evidence of residual ectopic gastric mucosa, the patient experienced a few further episodes of self-limiting mild acute pancreatitis during the following 3 years. The presence of heterotopic gastric mucosa in a duplicate gallbladder has not been described previously.

Retroperitoneoscopic nephroureterectomy of a horseshoe kidney in a child

Laparoscopic cholecystectomy is sometimes difficult due to complicated biliary anatomy including gallbladder duplication, a rare anomaly of the biliary tract. We report a case of duplicated gallbladder successfully removed under laparoscopy using endoscopic nasobiliary (ENB) tube cholangiography. A 61-year-old Japanese woman presented us with right upper abdominal pain. Ultrasonography revealed two cystic structures lying in the gallbladder fossa, and the upper one contained multiple stones. Endoscopic retrograde cholangiography showed two gallbladders, each of which has a cystic duct draining into the common bile duct separately. Laparoscopic cholecystectomy was planned under the preoperative diagnosis of double gallbladder with gallstones in the accessory gallbladder. The ENB tube was inserted just before the operation. Laparoscopic removal of the double gallbladder was successfully done using the ENB tube to identify the biliary tree anatomy and to close the stump of the cystic duct. In this communication, we would like to stress the usefulness of the ENB tube at the time of laparoscopic biliary surgery in patients with biliary anomalies including gallbladder duplication.

DUPLICATE GALLBLADDER DIAGNOSED WITH ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY AND TREATED WITH LAPAROSCOPIC CHOLECYSTECTOMY

A 44‐year‐old man was admitted to hospital because of sudden severe postprandial right epigastric pain. Abdominal echography showed multiple calculi in the gallbladder and evidence of a probable septum at the neck. Based on the results, tentative diagnoses were made of gallbladder calculosis with associated gallbladder curvature or malformation, and gallbladder adenomyomatosis. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) revealed a duplicate gallbladder consisting of two cystic ducts with two connected gallbladders. Laparoscopic cholecystectomy (Lap‐C) was performed. Inflammation of the Calot's triangle was mild. The two cystic ducts with one common bile duct were identified, and the cystic ducts separated by individual clipping. Duplicate gallbladder, a malformation of the gallbladder, has been reported to occur at an incidence of 0.02%. To date, a total of 60 cases have been reported in Japan, and recent cases have been treated with Lap‐C. In the present case, the surgery could be safely performed because the bifurcation of the cystic ducts could be identified by preoperative ERCP.

Accessory gallbladder originating from the right hepatic duct

A patient with symptomatic cholecystolithiasis underwent laparoscopic cholecystectomy after confirmation of the diagnosis by sonography. Intraoperative cholangiography was normal and the operation was completed laparoscopically. Due to the postoperative persistence of right upper abdominal pain, another sonogram and then an endoscopic retrograde cholangiogram (ERCP) were performed. To our surprise, an accessory gallbladder with a remaining gallstone was revealed. The accessory cystic duct was shown as arising directly from the right hepatic duct. The patient underwent a second laparoscopic cholecystectomy, but due to hemorrhaging the operation had to be converted to an open procedure. The two gallbladders and their corresponding cystic ducts and arteries were entirely separate. To our knowledge, this is the first publication of a duplicate gallbladder where the cystic duct arose directly from the right hepatic duct.

Duplicate Gallbladder Cholecystitis After Open Cholecystectomy

A 42-year-old man presented with acute right upper quadrant abdominal pain 2 years after open cholecystectomy. Evaluation revealed cholecystitis in a second gallbladder and a second cholecystectomy was performed. Acute right upper quadrant abdominal pain after cholecystectomy presents a wide differential diagnosis, including the often idiopathic and difficult to manage postcholecystectomy syndrome. Emergency physicians should be aware of the most common causes of pain in these patients. Previously unrecognized congenital abnormalities of the biliary system should be considered when the diagnosis is not clear, as highlighted by this case report.[Shapiro T, Rennie W: Duplicate gallbladder cholecystitis after open cholecystectomy. Ann Emerg Med May 1999;33:584-587.]

A stone in a grossly dilated cystic duct stump: a rare cause of postcholecystectomy pain

We describe the unusual case of a patient who developed recurrent right upper quadrant pain 25 yr after cholecystectomy. A cystic lesion containing a calculus was identified on transabdominal ultrasound, initially suggesting the possibility of gallbladder duplication. Endoscopic retrograde cholangiography identified this lesion as a massively dilated cystic duct stump. Surgical resection led to complete resolution of symptoms. Recurrent cholelithiasis involving the cystic duct stump may lead to massive dilatation, and must be considered in the differential diagnosis of postcholecystectomy syndrome.

Congenital gallbladder duplication: Preoperative diagnosis by ultrasonography

Congenital gallbladder duplication, an uncommon but potentially complicating malformation, is rarely diagnosed preoperatively. A case in which the diagnosis was achieved by real-time ultrasonography is presented and correlated with hepatobiliary scintigraphy. The efficacy of these diagnostic modalities is discussed, and the available literature is reviewed.

Congenital Duplication of the Gall Bladder

SUMMARY Because of the rarity of gall bladder duplication, it has seemed desirable to report a symptomatic case in which there was complete duplication of both gall bladder and cystic duct, and in which intravenous cholecystography was used in outlining the pathological gall bladder.
