Expanded Polytetrafluoroethylene Mesh in Chest-wall Reconstruction: A 27-year Experience.

OBJECTIVES: To evaluate the success of expanded polytetrafluoroethylene (ePTFE) mesh in chest-wall reconstruction. METHODS: We retrospectively reviewed patients who underwent ePTFE (Gore-Tex®) chest-wall reconstruction. The main outcome was a mesh-related event, defined as a mesh-related reoperation (e.g., mesh infection requiring debridement with/without explant, tumor recurrence with explant) and/or structural dehiscence/mesh loosening with/without a hernia. Demographics and surgical outcomes were reported. RESULTS: 246 reconstructions met inclusion (1994-2021). Fifty-five (22.4%) reconstructions had mesh-related events within a median of 1.08 years (IQR 0.08, 4.53) postoperatively; those without had a stable chest for a median of 3.9 years (IQR, 1.59, 8.23, p<0.001). Forty-one (16.6%) of meshes became infected, requiring reoperation. Eighty-eight percent (36/41) were completely explanted; 8.3% (3/36) required additional mesh placement. Predictors of mesh-related events were prior chest-wall radiation (OR=9.73, CI 3.47 to 30.10, p<0.001), higher BMI (OR 1.08, CI 1.01 to 1.16, p=0.019), and larger defects (OR 1.48, CI 1.02 to 2.17, p=0.042). The risk of mesh-related events with obesity was higher with prior chest-wall radiation. CONCLUSIONS: Most (78%) patients with an ePTFE mesh had a stable reconstruction after a median of 4 years. Obesity, larger defects, and prior chest-wall radiation were associated with a higher risk of a mesh-related event mostly due to mesh infections. Seventeen percent of reconstructions had reoperation for mesh infection; 88% were completely explanted. Only 8% required replacement mesh, suggesting that experienced surgeons can safely manage them without replacement. Future studies should compare various meshes for high-risk patients to help guide the optimal mesh selection.

Surgical Management of Swan Neck Deformity Following Mallet Finger Injury: A Review of 25 Patients Over 20 Years.

INTRODUCTION: Swan neck deformity develops as a sequela of chronic mallet finger. Surgical management can include soft tissue reconstruction or distal interphalangeal joint (DIPJ) fusion. Studies examining the incidence and management of posttraumatic swan neck deformity following mallet fracture are limited. METHODS: A retrospective, single-institution review of patients undergoing surgical management of swan neck deformity following a traumatic mallet finger from 2000 to 2021 was performed. Patients with preexisting rheumatoid arthritis were excluded. Injury, preoperative clinical, and surgical characteristics were recorded along with postoperative outcomes and complications. RESULTS: Twenty-five patients were identified who had surgical intervention for swan neck deformity. Sixty-four percent of mallet fingers were chronic. Median time to development of mallet finger was 2 months. Twelve (48%) mallet fingers were Doyle class I, 6 (24%) were class III, and 7 (28%) were class IVB. Forty percent of injuries failed nonoperative splinting trials. Sixteen (64%) underwent primary DIPJ arthrodesis, 8 (32%) underwent DIPJ pinning, and 1 underwent open reduction and internal fixation of mallet fracture. The complication rate was 50% overall, and 33% of surgeries experienced major complications. The overall reoperation rate was 33%. Proximal interphalangeal joint hyperextension improved by 11° on average. Median follow-up was 61.2 months. CONCLUSIONS: The development of symptomatic swan neck deformity following traumatic mallet finger injury is rare. All patients warrant an attempt at nonsurgical management. Attempts at surgical correction had a high rate of complications, and DIPJ fusion appeared to provide the most reliable solution.

No Increase in Complications With Intravenous Tranexamic Acid Use in Vaginoplasty: A Retrospective Study.

Background: Across surgical specialties, tranexamic acid (TXA) is applied to reduce intraoperative and postoperative bleeding. Within plastic surgery, both topical and intravenous routes are used. The application of TXA has yet to be examined in vaginoplasties. Methods: The authors performed a retrospective chart review of Mayo Clinic patients receiving penile inversion vaginoplasty from January 2017 through July 2021. Incidence of hematoma formation was assessed as the primary outcome. Secondary outcomes included perioperative hemoglobin, vaginoplasty complications, and possible TXA complications. These outcomes were compared across topical only (t-TXA), any intravenous (IV- TXA), and no TXA groups. Results: Of the 124 vaginoplasties, 21 patients received t-TXA only and 43 received any IV-TXA. Only 4 patients developed a hematoma; 2 were from the no TXA group and 2 were from the any IV-TXA group. There was no significant change in perioperative hemoglobin across groups. Analysis showed lower incidence of divergent urine stream (odds ratio [OR], 0.499 [95% confidence interval (CI)], 0.316-0.789], P = .003) and neovaginal stenosis (OR, 0.435 [95% CI, 0.259-0.731], P = .002) within the any IV-TXA group and no increased incidence of other complications. Conclusions: The use of either t-TXA or IV-TXA in vaginoplasty cases did not result in an increased rate of complications. There was no significant reduction in hematoma formation or postoperative hemoglobin decrease across groups.
