Instillation negative pressure wound therapy: An effective approach for hardware salvage.

Wound infection involving hardware can be notoriously difficult to treat, often requiring the removal of the infected implant. The goal of this study was to determine the utility of instillation negative pressure wound therapy to help eradicate infection and allow for definitive wound closure in patients without removing the infected hardware. A retrospective review was performed on the outcomes of 28 patients who presented with open wounds with exposed or infected hardware and who were treated with a combination of surgical debridement and negative pressure wound therapy with instillation (NPWTi). Eleven patients were treated for infected spinal hardware, 12 for extremity, and 5 for sternal hardware. Twenty-five of 28 (89%) patients had successful retention or replacement of hardware, with clearance of infection and healed wounds. Original hardware was maintained in 17 of 28 (61%) patients. In 11 patients, original hardware was removed, with subsequent replacement in eight of those patients after a clean wound was achieved. Average time to definitive closure was 12.6 days. Average follow-up was 135 days. This series supports NPWTi as an effective adjunct therapy to help expeditiously eradicate hardware infection, allowing for hardware retention.

Non-Lasered Drainage Retinotomies for Repair of Primary Rhegmatogenous Retinal Detachments.

BACKGROUND AND OBJECTIVE: Drainage retinotomies are a technique used for treating rhegmatogenous retinal detachments (RRDs). These retinotomies are commonly surrounded by barricade laser. This paper aims to evaluate operative success of non-lasered drainage retinotomies during 25-gauge pars plana vitrectomy (PPV) for repair of primary RRD. PATIENTS AND METHODS: Retrospective review of a consecutive interventional case series. Study includes 45 eyes of 45 patients who underwent 25-gauge PPV with a non-lasered drainage retinotomy for primary RRD. Eyes with previous retinal detachments or less than 3 months of follow-up were excluded. RESULTS: All PPV with non-lasered drainage retinotomies were carried out by one surgeon (RFI); 25-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and air or sulfur hexafluoride gas tamponade were utilized for each eye. Single surgery anatomical success was achieved in 42 out of 45 eyes (93%). CONCLUSION: Retinal detachment repair utilizing non-lasered drainage retinotomies had a high anatomic success rate comparable to that of standard retinal detachment repair.1,2 [Ophthalmic Surg Lasers Imaging Retina. 2018;49:955-960.].
