Surgical Strategies For Abdominal Wall Invasion And Implantation Of Colorectal Cancer

Background: Abdominal wall invasion and implantation (AWII) of colorectal cancer leads to complex complications and poor prognosis, which has a low efficacious treatment. We present our surgical strategies, which led to a relatively good outcome. Methods: Nineteen cases between February 2006 and July 2018 in our department were enrolled. Operations were divided into extensive resection and palliative resection, which was to eradicate the tumor and to mitigate tumor complications, respectively. The surgical strategies present included reasonable patient enrollment, precise classification of abdominal wall defect and appropriate repair technique for abdominal wall reconstructions. Results: Surgical treatments for AWII of colorectal cancer in our study proved as good methods to mitigate tumor complications and eradicate tumors. The immediate abdominal wall reconstructions were successful in all cases using the reinforcement repair technique (14 cases) and the double patch bridging repair technique (5 cases). Patients with type II abdominal wall defects after tumor resection had shorter operation times, shorter hospital stays and fewer postoperative complications than those with type III abdominal wall defects. The follow-up period ranged from 1 to 40 months. Only two patients developed abdominal wall hernias caused by tumor recurrence. Patients who had undergone extensive resection had a better long term survival time after surgery. Conclusion: Appropriate surgical treatment could be a good choice to prolong survival time and improve the quality of life for patients with AWII of colorectal cancer.
