ABSTRACT
Heterotopic gastric mucosa in the gallbladder is extremely unusual. In this study, we aimed to report a case of gastric heterotopia together with squamous metaplasia in the gallbladder of a 47-year-old female patient who experienced an intensive abdominal pain. He was admitted to the hospital for clinical treatment without any improvement. Ultrasonography showed a stone located in the gallbladder neck and dilatation of intrahepatic bile ducts, both hepatic ducts and common hepatic duct. Laparoscopic cholecystectomy was performed. In the microscopical examination, the epithelium of the gallbladder revealed an unspecified chronic cholecystitis. Besides, at the level of the gallbladder body, a heterotopic gastric mucosa contain chief, parietal and mucosal cells with cystic glands and squamous metaplasia was found. Actually the patient is in long-time follow-up, asymptomatic. We also review 96 other reports of HGM in the gallbladder in the international medical literature from 1934. As heterotopic tissue may promote carcinogenesis of the gallbladder, close attention should be paid to any occurrence of such lesions in this anatomical region. It appears that laparoscopic cholecystectomy may be unavoidable for patients affected by heterotopic gastric mucosa at the present time and care must be taken when a diagnosis is made based on intraoperative frozen sections.
RESUMEN
La heterotopía de la mucosa gástrica (HGM) en vesícula biliar es extremadamente rara. En este estudio, reportamos un caso de heterotopía gástrica junto con metaplasia escamosa en vesícula biliar de un paciente femenino de 47 años que experimentó un dolor abdominal intenso. Lo admitieron al hospital para el tratamiento clínico sin ninguna mejoría. Ultrasonografía demostró un cálculo situado en el cuello de la vesícula y dilatación de conductos biliares intrahepáticos, los conductos hepáticos y conducto hepático común. Se realizó la colecistectomía por vía laparoscópica. En el exámen microscópico el epitelio reveló una colecistitis crónica inespecífica. Además, en el nivel del cuerpo de la vesícula biliar fue hallada una mucosa gástrica heterotópica con células principales, parietales, células mucosas con las glándulas enquistadas y metaplasia escamosa. El paciente está en el seguimiento a largo plazo, asintomático. Revisamos 96 informes de HGM en vesícula biliar en la literatura médica internacional a partir de 1934. El tejido heterotópico puede promover la carcinogénesis de la vesícula biliar, por lo cual se debe prestar atención a cualquier ocurrencia de tales lesiones en esta región anatómica. La colecistectomía laparoscópica puede ser inevitable para los pacientes afectados por la mucosa gástrica heterotópica actualmente y todo cuidado debe ser tomado cuando se hace un diagnóstico por secciones congeladas intraoperatorias.
