[Limb necrotizing soft tissue infection (NSTI) and necrotising fasciitis: A bicentric study between 2000 and 2017 on the quality of life and functional impact]

INTRODUCTION

Limb necrotising soft tissue infection and necrotising fasciitis surgical debridement results in significant soft tissue losses. The purpose of this study was to evaluate the functional impact and the quality of life of survivors.

PATIENTS AND METHODS

This bicentric retrospective study included 62 patients treated for limb necrotising soft tissue infection and necrotising fasciitis (NSTI-NF) between 2000 and 2017. Demographic, clinic, biologic and surgical data were found in Patients Medical Records. Survivors at the moment of data collection (2018) were met; their quality of life was assessed using SF-36, DLQI, BSHS-B scores and their active joints motions were measured using a goniometer.

RESULTS

Twenty-one patients (87.1% of the living patients at this moment) were assessed. For the joint above the injury, mean loss of flexion was 9.19% and 5% for extension whereas for the joint under the injury, mean loss of flexion was 37.65% and 48.6% for extension compared to non-injured side. Mean quality of life scores were: SF-36p: 45.88, SF-36m: 51.31, DLQI: 10.48, BSHS-B: 105.81. The statistical analysis was not able to establish a correlation between loss of motion and quality of life.

CONCLUSION

We have not found a relationship between loss of joints motions and long term quality of life for those patients. High excised body surface area and high length of stay are correlated with high DLQI and thus a lower quality of life.

[Postoperative quality of life of patients with a bacterial necrotizing dermis-hypodermitis or necrotizing fasciitis, a ten-year study]

INTRODUCTION

Bacterial necrotizing dermis-hypodermitis and necrotizing fasciitis (BNDH-NF) are serious life-threatening soft-tissue infections. The object is to evaluate the quality of life (QOL) of patients who have been operated in our plastic surgery departement.

PATIENTS AND METHODS

This is a retrospective study of cases who have been treated at Nancy University Hospital between 2005 and 2014. We analyzed the perioperative data (demographic, clinical, bacteriological), the surgical data (excision, reconstruction) and the follow up data (consequences, mortality). The quality of life was assessed by the Short-Form 36 score, and the patients' satisfaction was assessed by a four-level scale.

RESULTS

We analyzed 23 patients with an average age of 60 years (28-84 years). The main comorbidities were diabetes (43 %) and obesity (39 %). The average number of surgical excision was about 1.9 (1-5) and the average excised body surface area was about 5 % (1-16 %). The short-term mortality was about 17 %. The mortality rate has been statistically correlated with the surgically excised body surface area (short-term 95 days: P=0.02; and long-term: P=0.003). The statistical analysis has shown a strong relative linear relationship between number of surgical excision and the physical score of QOL (P<0.001), between number of surgical excision and mental score of QOL (P=0.032), and between age and physical score of QOL (P≤0.021). The statistical analysis has also shown a strong relative linear relationship between E. coli infections and physical score of QOL (P=0.01). The percentage of patients' satisfaction in our study was evaluated at 86 %.

CONCLUSION

We have found that multiple surgical excisions, an advanced age of patients and E. coli infections have been associated with poor QOL. The mortality rate increased in relation with the importance of excised body surface. In spite of the gravity of these infections, our patients were satisfied of their treatment.
