Comparison of Harmonic scalpel and monopolar cautery for capsulectomy at the second stage of expander/implant breast reconstruction.

ABSTRACT: BACKGROUND:Capsular contracture is a common complication of two-stage expander/implant breast reconstruction. To minimize the risk of this complication, capsulectomy is performed using monopolar cautery or ultrasonic surgical instrumentation, the latter of which can be conducted with a Harmonic scalpel. To date, there is disagreement regarding which of the two methods is superior. The purpose of this study was to compare postoperative outcomes between a group of patients who underwent surgery using a Harmonic scalpel and another group treated with monopolar cautery. METHODS:A retrospective chart review was conducted of patients who underwent capsulectomy as part of two-stage breast reconstruction between January 2018 and February 2019 and who received at least 1 month of follow-up after surgery. Operative time and postoperative outcomes, including drainage duration, were analyzed. RESULTS:In total, 36 female patients underwent capsulectomy. The monopolar group consisted of 18 patients and 22 breasts, while the Harmonic scalpel group consisted of 18 patients and 21 breasts. There was no statistically significant difference in demographics between the two groups. The Harmonic scalpel group had a significantly shorter mean drainage duration (6.65 days vs. 7.36 days) and a smaller mean total drainage volume (334.69 mL vs. 433.54 mL) than the monopolar cautery group (P<0.05). No statistically significant difference was observed with regard to seroma or hematoma formation. CONCLUSIONS:The Harmonic scalpel approach for capsulectomy reduced the total drainage volume and drainage duration compared to the monopolar cautery approach. Therefore, this approach could serve as a good alternative to electrocautery.

Project description:BackgroundThe use of acellular dermal matrix (ADM) in one-stage immediate implant-based breast reconstruction (BR) may offer advantages over the two-stage expander-to-implant technique, but literature shows conflicting results. The aim of the present study was to compare these two techniques for immediate implant-based BR regarding postoperative complications, aesthetic correction procedures and aesthetic outcome.MethodsThe study was designed as an observational cohort study with 44 participants admitted for immediate implant-based BR at Department of Plastic Surgery, Aarhus University Hospital, Denmark. 21 patients underwent BR with a one-stage direct-to-implant technique using ADM and 23 patients underwent BR with a two-stage expander-to-implant technique. Follow-up time was 2 years.ResultsThe risk of implant loss was equal between groups; one-stage group 16% and two-stage group 17% whereas the risk of implant exchange (but not loss of BR) was 13% in the one-stage group compared to 7% in the two-stage group. The risk of at least one major complication were equal between groups; 28% and 24% but the risk of at least one minor complication was significantly higher in the two-stage group (41%) compared to the one-stage group (3%). Number of aesthetic corrections were equally frequent in the two treatment groups (one-stage group 1.8, two-stage group 1.5). Patient and investigator assessed aesthetic outcome was very high in both groups as well as the degree of symmetry between breasts. No capsular contracture Baker grade 3 or 4 was observed.ConclusionsThe present study design sets limitations for drawing wide conclusions. This study did not reveal any significant differences between the two breast reconstructive techniques besides a higher risk of minor complications in the two-stage group, that did, however, not lead to a higher risk of implant loss. With equally high satisfaction with the aesthetic result and no significant difference in number of aesthetic corrections between the two groups we suggest, that the one-stage approach using ADM may be feasible and allows the patient to achieve an implant-based BR with a minimum of surgeries and outpatient visits. The study was registered in ClinicalTrials.gov (NCT04209010).
