Detached pyloric gland adenoma of gallbladder: A case report and review of literature.

Abstract

Vigilant intraoperative inspection is crucial during gallbladder surgery to detect any abnormal tissue including the rare pyloric gland adenomas, which can be easily missed. Thorough examination and removal of unusual lymph nodes or thickened tissues are essential to prevent the risk of malignant transformation and ensure comprehensive patient care. Pyloric gland adenomas are uncommon tumors that can be discovered in various organs such as the stomach, gallbladder, and pancreas. Typically lacking noticeable symptoms, these tumors are categorized into subtypes, with the pyloric variant being the most frequent. The term "intracholecystic papillary-tubular neoplasms (ICPN)" is used to emphasize growth patterns and associated risks. In a discussed case, a detached pyloric gland adenoma was identified incidentally during a cholecystectomy procedure. A 58-year-old obese male presented with upper abdominal pain, nausea, and vomiting. He was diagnosed with early cholecystitis caused by gallstones. Subsequently, during a laparoscopic cholecystectomy, a detached adenoma was discovered. Vigilant screening is crucial, as the identification of gallbladder pyloric gland adenomas is a rare occurrence that might be missed during gallbladder surgery. Any unusual lymph nodes or thickened tissues found in association with the gallbladder ought to be carefully removed, as they could potentially indicate detached gallbladder adenomas with a significant risk of becoming malignant. Failing to consider this possibility may subject the patient to prolonged risks if not meticulously examined.
