Incidentally detected gallbladder agenesis in a child: the importance of identifying anatomic structure

The absence of a gallbladder is a very rare anomaly. While it is usually asymptomatic, it can cause biliary colic symptoms. For these reasons, gallbladder agenesis can be misdiagnosed as a hepatobiliary disease and is diagnosed correctly after surgery. This condition may also be detected through an autopsy for other causative diseases. Abdominal ultrasonography is used as a diagnostic method to detect gallbladder agenesis. Hepatobiliary scintigraphy, magnetic resonance cholangiopancreatography, and endoscopic cholangiopancreatography are also used to make a more accurate diagnosis. In the emergency room, however, gallbladder agenesis can still be misdiagnosed as acute or chronic cholecystitis, leading to the detection of gallbladder agenesis in the operating room. Although some cases of gallbladder agenesis detected in adults during surgery have been reported in Korea, there are no reports of gallbladder agenesis in pediatric patients to date. This paper reports a case of gallbladder agenesis in a symptomatic child that was detected incidentally by a radiographic examination.

Agenesia de la Vesícula Biliar asociada a pancreatitis aguda recurrente. Presentación de caso / Gall bladder agenesis associated with recurrent acute pancreatitis. Case presentation

Introducción: La Agenesia de la Vesícula Biliar es una anomalía congénita rara, entre 13 y 65 por ciento por cada 100 000 habitantes. Su asociación con pancreatitis aguda es extremadamente rara. Objetivo: Presentar un caso de Agenesia de la Vesícula Biliar asociada a pancreatitis aguda recurrente. Presentación del caso: Se presenta una mujer de 85 años, con antecedentes de litiasis vesicular por ultrasonido (US), y crisis de dolor abdominal, vómitos e hipotensión frecuentes, a quien remitían con tratamiento médico. Acudió al hospital con dolor abdominal, vómitos e hipotensión. Al examen físico se constató: dolor epigástrico, sin reacción peritoneal ni tumor palpable. El US informó vesícula no visible. En menos de 24 horas evolucionó con shock, disfunción múltiple de órganos y muerte. En la necropsia se encontró Agenesia de la Vesícula Biliar (AVB) y pancreatitis aguda necrotizante. Conclusiones: La AVB es una anomalía congénita rara, de difícil diagnóstico preoperatorio, por lo que casi siempre es un hallazgo de la cirugía abdominal o en la autopsia. Su asociación con pancreatitis aguda es rara. La pancreatitis puede ser debida a Disfunción del Esfínter de Oddi o de origen idiopático(AU)

Introduction: Gallbladder agenesis (GA) is a rare congenital anomaly, with a reported incidence ranging between 13-65 percent a 100 000 population. Its association with acute pancreatitis is extremely rare. Objective: To present a case of GA associated with recurrent acute pancreatitis. Case Presentation: We present an 85 years old woman whose clinical record reported a bladder stonediagnosis by US, that arrive to the hospital with frequent episodes of intermittent vomiting, abdominal pain and hypotension. She was admitted at hospital with upper abdominal pain, vomiting and hypotension. At the physical examination the abdomen was soft, with mild epigastric tenderness, without tenderness rebound or tumor. US report gallbladder not visible. In less than 24 hours the patient evolved with shock, multiple organ failure and death. Gallbladder agenesis and acute pancreatitis were found in autopsy. Conclusions: The GA is a rare congenital anomaly, difficult to establish a correct preoperative diagnosis, always found during the abdominal surgery or autopsy. Its association with acute pancreatitis is very uncommon. Pancreatitis may be due to of Oddi Sphincter's Dysfunction (SOD) or idiopathic origin(AU)

Agenesia del lóbulo hepático derecho asociado a agenesia vesicular / Agenesis of the right hepatic lobe associated with gallbladder agenesis

Background: Anatomical abnormalities of the liver are rare and their association with gallbladder agenesis are even more uncommon. Case report: We report a 63 years old man complaining of jaundice, without pain or fever. A magnetic resonance imaging showed a right hepatic lobe agenesis associated with gallbladder agenesis. Jaundice subsided spontaneously.

Introducción: Las anomalías anatómicas del hígado son raras, la asociación a una agenesia vesicular es más infrecuente aún, siendo su diagnóstico generalmente un hallazgo. Caso clínico: Presentamos el caso de un paciente masculino de 63 años que consulta por ictericia, sin dolor ni fiebre, al cual se le realiza diagnóstico por imagen con resonancia magnética de agenesia de lóbulo hepático derecho asociado a agenesia vesicular. Dado que el paciente no tiene litiasis biliar, se decide tratamiento médico.
