Abstract:
Objective To investigate the means which can prevent postoperative incision infection of elderly patients with obstructive colorectal cancer. Methods Sixty-seven cases of elderly patients with obstructive colorectal cancer adopting surgical treatment were divided into two groups, including experimental group with 37 cases and control group with 30 cases. Put self-made negative pressure drainage tube with side-hole into subcutaneous interspace of abdominal incision of experimental group alter operation, kept continuous negative pressure drainage 7-10 d and pull out the self-made subcutaneous negative pressure drainage tubes till drainage volume decreased obviously. The abdominal wall incisions of the control group were given conventional suture. Results Incision infection occurred in only one case (2.7%) and no incision dehiscence occurred in the experimental group, and incision healing time was (9.36 ± 2.18) d. Incision infection occurred in 7 cases (23.3%) in the control group, of which there were 3 cases (10.0%) of wound dehiscence, incision healing time was (12.25 ±4.06) d. Incision infection rate of the two groups had significant difference (χ2= 6.706,P < 0.05), incision dehiscence rate of the two groups had no significant difference (P 0.05), incision healing time of the two groups had significant difference (t = 6.676, P < 0.05). Conclusion Using the self-made subcutaneous negative pressure drainage tube and keeping it continuous negative pressure drainage after operation can be effective in preventing incision infection of elderly patients with obstructive colorectal cancer, and promote wound healing.
