A transhepatic gallbladder is an exceedingly rare finding that presents unique challenges for the general surgeon who often encounters it unexpectedly. A sonogram will not demonstrate it. A gallbladder that wholly penetrates the right lobe of the liver and is clearly visible on the anterior surface is an enigma. We describe an incidental finding at the time of elective surgery of such a phenomenon. This presented the author with a unique problem - how to remove the entire gallbladder without leaving a hole in the right lobe of the liver through which bowel could herniate. A novel technique was utilized which left a small bridge of cauterized gallbladder fundus wall. This article delves into the embryology of the hepatobiliary system in order to surmise how this could have occurred during development. This transhepatic gallbladder also contained a septum, dividing the gallbladder transversely into unequal parts. We hope that our findings and operative description will assist future surgeons that encounter a similar anatomic problem.

“…These anomalies have a rare occurrence of 0.1% to 0.7%. 2 They are discovered intraoperatively in the majority of cases, thus causing perioperative challenges. The most common anomalous locations of ectopic gallbladders are beneath the left hepatic lobe, intrahepatic, transverse, and retrohepatic/retroperitoneal.…”

“…Moreover, ectopic gallbladders located beneath the left hepatic lobe are susceptible to herniation through the foramen of Winslow. For these reasons, it has been suggested that an ectopic gallbladder should be resected when found [ 6 ].…”

Ectopic gallbladder with congenital biliary dilatation: a pediatric case report

et al. 2022

Background An ectopic gallbladder is a rare anomaly and can result in the misinterpretation of imaging findings and clinical confusion. Knowledge of such anomalies facilitates accurate diagnoses and prompt management. We report a pediatric case of an ectopic gallbladder concomitant with congenital biliary dilatation (CBD). Case presentation A 9-year-old girl was referred to our hospital for elevated liver enzyme levels. Following physical examination and a review of medical imaging findings, she was diagnosed with Todani type IV-A CBD. We could not visualize the gallbladder by abdominal ultrasonography, CT, and MRI scans; therefore, we suspected gallbladder agenesis. A laparoscopic excision of the extrahepatic bile duct was performed to treat the CBD. Neither a gallbladder nor a cystic duct were revealed on the liver undersurface. Therefore, gallbladder agenesis was considered as a diagnosis based on preoperative imaging and intraoperative findings. However, during dissection of the hepatic hilum, a cyst-like structure was found on the ventral side of the common hepatic duct, slightly to the right, and a small additional duct that originated from the cystic structure was found. Upon incision, a small amount of bile was drained from the small duct. Thus, the cystic structure was diagnosed as an ectopic gallbladder with hypoplasia. Following the removal of the ectopic gallbladder, the extrahepatic bile duct was excised. Subsequently, laparoscopic Roux-en-Y hepaticojejunostomy was performed without any complications. Postoperative histopathological evaluations of the resected specimen revealed Rokitansky–Aschoff sinuses in the resected cystic lesion. The pathological investigations confirmed the diagnosis of an ectopic gallbladder. Following an uneventful postoperative course, the patient was discharged on day nine. Conclusions To our knowledge, this is the first pediatric case report describing an ectopic gallbladder concomitant with CBD. If the gallbladder cannot be detected in a preoperative imaging examination, it is important to consider the possibility of an ectopic gallbladder.
