3D Laparoscopic Gossypiboma Resection in the Preperitoneal Space: A Case Report

A 38-year-old male patient with a history of right inguinal hernia surgery 18 years previously presented with epigastric pain. An examination revealed advanced gastric cancer. Abdominal CT demonstrated a 6-cm mass with well-defined borders and heterogeneous internal density in the pelvis to the right side of the bladder, and fluorodeoxyglucose positron emission tomography (FDG-PET) found marginal FDG accumulation in the periphery of the mass. Given the patient's history, a retained surgical sponge (RSS), known as gossypiboma, was suspected. Resection of the lesion was performed using 3D laparoscopy, which confirmed the mass to be gossypiboma. The use of 3D laparoscopy reduced the invasiveness of the procedure and clarified the tumor's relationship with the surrounding organs.
