Short-term efficacy and adverse effects of collagenase clostridium histolyticum injections, percutaneous needle fasciotomy and limited fasciectomy in the treatment of Dupuytren’s contracture: a network meta-analysis of randomized controlled trials

Comparing Collagenase and Tissue Subcision for Cellulite Treatment of the Buttock and Thigh Regions: A Systematic Review and Meta-analysis

Background

In this systematic review, we assessed the therapeutic efficacy and safety of Clostridium histolyticum collagenase (CCH) and tissue subcision (TS) for treating cellulite, which ranges from subtle to pronounced lesions.

Methods

A systematic review was performed following PRISMA guidelines for CCH and TS treatment to the thigh and gluteal regions. A proportion meta-analysis was then conducted using Stata statistical software.

Results

A total of 14 studies were incorporated into the final analysis. Nine focused on TS and five on CCH injection, collectively reporting outcomes for 1254 patients. Of these, 465 received CCH injection and 789 underwent subcision. For bruising, rates were 89% [95% confidence interval (CI), 71%-96%] with CCH injection and 99% (95% CI, 85%-99%) for subcision; pain requiring analgesic was reported at 74% (95% CI, 55%-87%) for CCH and 60% (95% CI, 43%-76%) for subcision; both showed induration at 7% (95% CI, 5%-11% for CCH, 95% CI, 2%-25% for subcision), whereas skin discoloration was higher post-CCH injection at 16% (95% CI, 10%-26%) compared with 7% (95% CI, 5%-10%) postsubcision.

Conclusions

Both CCH and TS seem effective treatments for cellulite. However, upon evaluating the adverse outcomes between the two modalities, subcision demonstrated a higher incidence of bruising, albeit similar rates of induration compared with CCH injection. Conversely, the CCH injection group manifested a higher propensity for pain requiring analgesia and notably exhibited increased instances of skin discoloration compared with their subcision patient group. Further standardized research is crucial for more informed cellulite treatment decisions and for comparing efficacy, safety, and cost-effectiveness between TS and CCH.

Surgery, Needle Fasciotomy, or Collagenase Injection for Dupuytren Contracture : A Randomized Controlled Trial

BACKGROUND

Surgery, needle fasciotomy, and collagenase injection are used to treat Dupuytren contracture. The treatment decision requires balancing initial morbidity and costs of surgery against its potential long-term benefits over needle fasciotomy and collagenase.

OBJECTIVE

To compare the effectiveness of surgery, needle fasciotomy, and collagenase injection at 3 months and 2 years (secondary time points of the trial).

DESIGN

A multicenter, randomized, outcome assessor-blinded, superiority trial. (ClinicalTrials.gov: NCT03192020).

SETTING

6 public hospitals in Finland.

PARTICIPANTS

302 persons with treatment-naive Dupuytren contracture (contracture angle <135°).

INTERVENTION

Surgery (n = 101), needle fasciotomy (n = 101), or collagenase (n = 100).

MEASUREMENTS

The primary outcome was the success rate, defined as greater than 50% contracture release and patients reaching the patient acceptable symptom state. Secondary outcomes included hand function, pain, quality of life, patient satisfaction, residual contracture angle, finger flexion, risk for retreatment, and serious adverse events.

RESULTS

A total of 292 (97%) and 284 (94%) participants completed the 3-month and 2-year follow-ups. Success rates were similar at 3 months: 71% (95% CI, 62% to 80%) for surgery, 73% (CI, 64% to 82%) for needle fasciotomy, and 73% (CI, 64% to 82%) for collagenase. At 2 years, surgery had superior success rates compared with both needle fasciotomy (78% vs. 50%; adjusted risk difference [aRD], 0.30 [CI, 0.17 to 0.43]) and collagenase (78% vs. 65%; aRD, 0.13 [CI, 0.01 to 0.26]). Secondary analyses paralleled with the primary analysis.

LIMITATION

Participants were not blinded.

CONCLUSION

Initial outcomes are similar between the treatments, but at 2 years success rates were maintained in the surgery group but were lower with both needle fasciotomy and collagenase despite retreatments.

Collagenase clostridium histolyticum injection versus limited fasciectomy for the treatment of Dupuytren's disease: a systematic review and meta-analysis of comparative studies

INTRODUCTION

The aim of the present study is to systematically review the literature on well-selected comparative studies for meta-analysis on outcome differences between collagenase clostridium histolyticum (CCH) injection and limited fasciectomy (LF) for Dupuytren's disease.

MATERIALS AND METHODS

PubMed/Medline, Embase, and the Cochrane Library were searched for comparative studies assessing differences in outcomes of CCH and LF. Effect estimates were pooled across studies using random effects models and presented as weighted mean difference (MD) and odds ratio (OR) with corresponding 95% confidence interval (CI).

RESULTS

A total of 11 studies encompassing 1'051 patients was included (619 patients in the CCH and 432 in the LF group). The residual contracture at a minimal average follow-up of three months was higher in the CCH group than in the LF group (27.8 vs. 16.2°, MD 11.6°, 95% CI [8.7, 14.5°], p < 0.001). The recurrence rate was significantly higher in the CCH group (25.8 vs. 9.3%, OR 5.2, 95% CI [1.5, 18.8], p = 0.01) while the rate of severe complications was significantly higher in the LF group (0.3 vs. 7.3%, OR 0.12, 95% CI [0.03, 0.42], p = 0.001).

CONCLUSIONS

Evidence of the present study confirms that CCH injection has a higher rate of disease recurrence whereas LF carries a higher risk for severe complications. It's imperative that the trade-off between these aspects is considered, keeping in mind that CCH injections may be repeated in case of disease recurrence without increasing procedure related risks, especially in complex cases.

Patient-Reported Outcome in Dupuytren's Disease Treated With Fasciectomy, Collagenase or Needle Fasciotomy: A Swedish Registry Study

Purpose

This registry study compares the patient-reported outcomes of 3 treatments for Dupuytren´s disease: open fasciectomy (OF), collagenase injection (CCH) and percutaneous needle fasciotomy (PNF).

Methods

From the Swedish national quality registry for hand surgery (HAKIR) we included 2,585 procedures (in 2,414 patients): 1,200 treatments were OF, 918 CCH, and 467 PNF. The choice between CCH and PNF varied mainly because of regional differences in reimbursement of CCH. We report the results of the validated patient-reported outcome instrument HQ-8. HQ-8 evaluates symptoms in the treated hand and is issued before treatment, 3 and 12 months after treatment and is used for all patients in HAKIR.

Results

At 3-month follow-up, patients treated with CCH or PNF experienced less stiffness, weakness, numbness, tingling and sensitivity to cold. At 12 months, the differences among the 3 treatments were smaller, but CCH patients experienced less stiffness and weakness compared to PNF-treated patients.

Conclusions

Most randomized controlled trials have not shown significant differences in recurrence rates or patient-reported outcomes between CCH and PNF, but the number of patients has been limited and no randomized controlled trials have included all 3 treatments. In the present study, we compared registry data on patient-reported outcomes for OF, CCH, and PNF in a real-life clinical setting. Our results confirm that the noninvasive treatments (CCH and PNF) cause less disability than OF and indicate a possible advantage of CCH compared to PNF regarding stiffness and weakness at 1 year after treatment based on patient-reported outcomes. Patient-reported residual symptoms are important to consider when informing patients and selecting treatment for Dupuytren´s disease.
