Primary wound closure of diabetic foot ulcers by debridement and stitching.
OBJECTIVE
The role of stitching in healing diabetic foot ulcers (DFUs) has little attention, with few reports published on the technique. This study aimed to report on the role of stitching in healing of neuropathic DFUs.


METHODS
This comparative study was between patients with diabetes with neuropathic foot ulcers who had undergone wound stitching and those on conventional wound care. The study was carried in Jabir Abu Eliz Diabetic Center Khartoum (JADC) during between January 1 2011 and January 1 2013. All patients presented with neuropathic diabetic septic foot on the plantar aspect or extending up the leg were included. Initial surgical sharp debridement under intravenous broad spectrum antibiotics was performed and oral antibiotics were given 3 days later after the results of the bacterial culture were received. Regular wound debridement was performed with the aim of pairing the wound edges for stitching. Primary closure was performed when the wound was clean from any necrotic tissues and partial closure when the wound was still oozy to secure drainage and avoid splaying of the wound edges. All patients were using either crutches or wheel chair initially until any sepsis cleared and then proper off-loading by shoes purpose made in our centre.


RESULTS
A 160 patients with neuropathic DFUs that needed debridement and frequent dressing changes as outpatients were included. Both groups had the same tap water wound dressing either daily, every other day or every two days according to the wound progress. Absorbent dressings and negative pressure wound therapy (NPWT) were unavailable. Half of the patients (n=80) had debridement, frequent dressing change using tap water throughout the period of study (group 1) while the rest (n=80) in addition to wound debridement underwent stitching of their wounds (group 2). Complete healing was achieved in 46 patients in Group 1 (57.5%) compared with 19 patients (23%) in group 2 (p=0.001). The average number of dressings used was 19 in stitch group compared with 30 in the non-stitch group (p=0.000). The average duration of healing in stitch group was 2.9 months compared with 5.7 months in non-stitch group (p=0.000).


CONCLUSIONS
Stitching of neuropathic DFUs reduced the duration of wound healing and the frequency of wound dressing change.
