ObjectiveTo present the functional results obtained and the possible surgical difficulties after the surgical treatment of Dupuytren's disease (DD) recurrence in patients previously treated with Clostridium histolyticum (CCH) collagenase.Materials And MethodsIn this prospective study, 178 patients with DD were treated with CCH from 2011 to 2018; During long-term postoperative follow-up, 34 patients (19.1%) had recurrence of DD. In all patients injected in the IFP the disease recurred; In patients injected in the MCP, recurrence was highest in grade III and IV of the Tubiana classification, with involvement of the 5th finger and the two-finger Y-chord. Fourteen patients (7,8%) required surgery by partial selective fasciectomy due to recurrence of cord DD infiltration. The clinical and functional results of the patients, the difficulty of the surgical technique and the anatomopathological analysis of the infiltrated cords were evaluated in comparison with those of cords and patients who had had no previous CCH treatment.ResultsIn all patients, cord rupture was achieved after injection, reducing joint contracture. In 14 patients, we observed during the follow-up the existence of DD recurrence that required surgical treatment by selective partial fasciectomy. There were no major difficulties in surgery and good clinical and functional results at 6 months of follow-up. The anatomopathological study of the resected tissue did not present histological alterations with respect to the samples obtained from patients initially treated by selective partial fasciectomy.ConclusionsSelective fasciectomy after CCH injection does not lead to important operative difficulties, as long as the CCH injection is performed according to the recommendations. There were no histological changes in the tissue after CCH injection.Level Of EvidenceIII.© 2024. The Author(s).
