[Port Site Recurrence after Laparoscopic Distal Gastrectomy for Advanced Gastric Carcinoma-A Case Report].

A 67-year-old female was admitted to our hospital for the diagnosis of gastric cancer with pyloric stenosis. Upper gastrointestinal endoscopy and computed tomography(CT)revealed a type 3 tumor in the prepyloric region without evidence of distant metastasis. Laparoscopic-assisted distal gastrectomy with D2 lymph node dissection was performed, and the final diagnosis was T4(SE)N1M0, Stage ⅢA. Adjuvant therapy was not administered because the patient suffers from schizophrenia. Twelve months after the initial resection, a mass was palpated at the trocar site in the right hypochondriac region. A core needle biopsy was performed, revealing adenocarcinoma. Abdominal CT showed the mass to be localized above the fascia of the abdominal wall, with no evidence of distant metastasis or peritoneal dissemination. The mass was surgically resected, and the final pathology report confirmed port-site recurrence of gastric cancer. Nine months after the second resection, there were no signs of recurrence.
