To investigate the clinical effect of microskin transplantation in repairing obese diabetic lower limb ulcer wounds.

A retrospective analysis of 34 obese diabetic patients with foot ulcers diagnosed and treated in our hospital from 2014 to 2020, including 21 males and 13 females; aged 61-74 years old. Wound debridement with or without Vacuum Sealing Drainage (VSD) were used before microskin transplantation. The area of the ulcer wound, the area of the skin removed, and the expansion ratio of the micro-skin to evaluate the healing rate and healing rate were recorded, and the healing quality and scar formation of the wound also was evaluated.

The average wound area of 34 patients was (42.7±31.2) cm², the average skin area was (12.1±9.3) cm², and the microscopic skin expansion ratio was 8:1-5:1. The average primary healing rate of 34 patients was (92.3±4.7)%. There was no statistically significant difference in healing rate and healing rate between combined VSD negative pressure and non-VSD negative pressure suction debridement treatment. The overall excellent healing quality of the recent wounds at 3 months after surgery reached 97.1%; follow-up scars after half a year A total of 19 cases (55.9%) were mild, 11 cases (32.3%) were moderate, and 4 cases (11.8%) were severe.

Microskin transplantation to repair obese diabetic lower limb ulcer wounds has the characteristics of high healing rate and good healing quality, and it is worthy of further promotion and application.
