[A case report of wound-site recurrence two years after laparoscopic colectomy for colon cancer]

The patient in this case was a 72 year-old female with total blindness and dementia. We found a tumor in the recto-sigmoid colon, which had developed across the entire circumference. We performed a laparoscopic colectomy for advanced cancer. A Multi Flap Gate(MFG) was inserted through a 4 cm median incision above the umbilicus to protect the wound margin from bacteria and cancer cell implantation. Cytodiagnosis of ascites was negative. When we pulled the tumor out through MFG, a part of the tumor ruptured. Histopathological diagnosis was type 2, tub2, SS, ly1, v1, N0, M0, Stage II. Two years after the operation, a tumor was palpated at the umbilical region. We diagnosed it as an abdominal wall recurrence through imaging and cytological analysis of an aspiration biopsy. To prevent metastases to other parts of the body and decrease tumor size, chemotherapy with capecitabine was performed with careful monitoring. Since the tumor became smaller and there was no recurrence in other organs, an abdominal wall resection was performed. We carried out en block resection of the abdominal wall including the operative scar and the umbilicus part. We report a case of wound-site recurrence 2 years after laparoscopic colectomy for colon cancer.
