Effect of component separation technique in the treatment of abdominal wall defect after resection of abdominal wall tumor / 中华普通外科杂志

ABSTRACT

Objective:To evaluate component separation technique (CST)for the managetment of abdominal wall defect after resection of abdominal wall tumor.Methods:Clinical data of 12 patients treated by CST form Jan 2016 to Jan 2019 at our two Hospitals were retrospectively analyzed. The abdominal wall defect after tumor radical resection were reconstructed with synthetic mesh.Results:The most common pathological type was dermatofibrosarcoma protuberans (4 cases), followed by desmoid fibroma (2 cases) and abdominal metastasis of colon cancer (2 cases). The maximum diameter of tumor was (5.3±1.5) cm by CT preoperatively.The largest transverse diameter of abdominal wall defect after tumor resection was (9.4±1.4) cm.7 patients were treated with CST. 10 patients used synthetic mesh. Incision-related complications occurred in 3 patients, abdominal hypertension and atelectasis in 1 case and acute myocardial infarction in 1 case. All patients were helped and discharged.One patient died of liver metastasis of colon cancer 17 months after operation, and the other 11 patients had no recurrence of tumor or incisional hernia.Conclusion:Using CST in patients with abdominal wall tumor can effectively close the defect, reconstruct the function of abdominal wall and prevent the occurrence of incisional hernia.
