To explore the clinical effect of composite mesh for repairing massive abdominal wall defect after abdominal wall tumor resection.

The clinical data of 55 patients with massive abdominal wall defect after abdominal wall tumor resection in the Fourth Affiliated Hospital of Xinjiang Medical University from February 2015 to August 2017 were retrospectively analyzed, they were divided into the experiment group (n=35) and the control group (n=20) according to the different mesh implanted. The two groups underwent abdominal wall tumor resection, the experiment group was implanted with Johnson Proceed mesh, the control group was implanted with Bard Composix Kugel mesh. The clinical parameters, pain degree at different time before and after surgery, the situation of healing of the incision, complications, tumor recurrence and metastasis in the two groups were compared.

There was no significant difference in time of implanting mesh and postoperation spontaneous activity time between the two groups (P>0.05). The visual analogue score (VAS) from 12 hours to 7 days of postoperation gradually decreased in the two groups (P<0.05), and which were significantly lower than of preoperation (P<0.05), but there was no significant difference between the two groups (P>0.05). After suture removed, the wounds all reached the first stage of healing, there was no significant difference in the incidence of total complications between the two groups (P>0.05). The follow-up period was 1 year, there was one case of tumor recurrence in the experiment group, one case of distant metastasis in the control group. The abdominal wall repair material was smooth, and no adhesion between the abdominal wall repair material and the intestinal tube was observed in the two groups.

The clinical effect of restoration and reconstruction of massive abdominal wall defect after abdominal wall tumor resection using Johnson Proceed mesh or Bard Composix Kugel mesh is good and safety.
