[A Case of Port Site Recurrence of Gallbladder Carcinoma after Laparoscopic Cholecystectomy].

The patient was a 76-year-old man who underwent laparoscopic cholecystectomy with a diagnosis of cholecystolithiasis. Since the definite diagnosis of gallbladder carcinoma was made after the operation, he underwent additional resection. Four years later, he revisited the hospital complaining of painful swelling of the port site of his epigastrium. Magnetic resonance imaging of the abdomen revealed a mass 3.4 cm in diameter at the epigastrium. Thus, port site recurrence of gallbladder carcinoma was the suspected diagnosis. We resected the peritoneum, rectus abdominis muscle, and skin, as well as the tumor, and the abdominal wall was reconstructed using synthetic composite mesh. Histological examinations revealed recurrence of gallbladder carcinoma. Port site recurrence of gallbladder carcinoma is known to have a poor prognosis, but long survival can be expected in patients after complete resection of the metastatic lesion, if the recurrence develops more than a year after the initial operation.
