The prothesis of the immense abdominal wall defect after resection of malignant tumors / 中华普通外科杂志

ABSTRACT

Objective To evaluate the repair of the immense abdominal wall defect after resection of malignant tumours occurred primarily in the abdominal wall or that invaded the abdominal wall secondarily. Methods Among the 20 eases, 12 eases were of malignant tumours within abdominal wall (9 eases of rhabdomyosareoma, 3 eases of malignant fibrous histocytoma), 8 eases with the invasion of abdominal wall from malignant turnouts were of retroperitoneal or intraabdominal malignant tumors (3 eases with retroperitoneal malignant tumours, 1 ease of transverse eolon carcinoma, 3 eases with local reeurrenee in abdominal wall of ascending colon carcinoma undergoing fight hemieoleetomy 2～3 years ago, 1 ease with abdominal wall implantation metastasis of renal carcinoma after resection 5 years ago ). Abdominal wall defects left over by resection were repaired with polypropylene and expanded polytetrafluoroethylene (PPePTFE) mesh. The postoperative eomplieation and healing rate were observed. Results Wounds healed by primary intension, with no subeutaneous hydrops, no incision infeetion, dehiscence and hernia, no intestinal adhesion in all eases. The rate of successful repairing for the abdominal defect was 100%. All patients were followed up, the meshes with no rejection, inflammation and incision hernia, no reeurrenee of tumour in the repaired abdominal wall. Conclusion The PP-ePTFE mesh is a favourable repairing material for the abdominal defect after tumour resection, with the advantages of strong tensility, good bioeompatibility.
