Analysis of Pathogenesis,Prevention and Treatment of Implantation Metastases of Abdominal Wall

Objective To investigate the pathogenesis,prevention and treatment of implantation metastases of abdominal wall. Methods 7 patients with implantation metastases of abdominal wall were analyzed retrospectively. Results There was no effective prevention measure to be taken in operative procedure for all patients.2 patients were taken simple biopsies and 5 were treated by operations combined with radiotherapy and/or chemotherapy.1 patient with tumor recurrence died 34 months after reoperation,2 died 1 month after biopsies,and 4 were followed up for 3 to 27 months and were still alive. Conclusion Exfoliatation of tumor cells and lack of effective wound protection are the main causes of implantation metastasis of abdominal wall.It is very important to avoid direct contact between tumor cells and wound.The treatment of the complication depends on whether or not have intra-abdominal metastasis and systemic failure.
