Giant intracholecystic papillary tubular adenoma of the gall bladder with gall stones in an elderly woman; case report

Gall bladder polyps occur in 0.4% of patients undergoing cholecystectomy, the majority of gall bladder polyps are benign, they are classified into 3 types: epithelial or adenomatous polyps, mesenchymal polyps, and pseudopolyps. Gall bladder polys mostly affect females and those more than 50 years of age. Ultrasound is a very sensitive tool in the diagnosis. An 88-year-old woman presented with epigastric pain and right hypochondrial pain, fever, and vomiting for 1 week. Clinical examination showed jaundice and tenderness at the right hypochondrial region. Investigations showed elevated WBC, bilirubin level and the alkaline phosphatase. MRCP showed multiple gall stones with a large irregular polyp in the fundus of the gall bladder, and dilated common bile duct with multiple stones in the lumen of common bile duct. Cholecystectomy was done with exploration of the common bile duct with extraction of stones, T-tube was placed inside the CBD. At the 14th day T-tube cholangiography was done which showed passage of the dye to the duodenum, the tube was extracted and the patient was discharged home with no postoperative complications. The histopathology showed intracholecystic papillary tubular adenoma of the gall bladder with no evidence of malignancy. The general indications of surgery for gall bladder polyps include the size if more than 10 mm especially if solitary, the presence of associated gall stones, the age if more than 60 years, and if the polyps are causing symptoms. In this patients the large size of the polyp and obstructive jaundice were the two indications for surgery.
