ABSTRACT

BACKGROUND/IMPORTANCE: Neuropathic amputation-related pain can consist of phantom limb pain (PLP), residual limb pain (RLP), or a combination of both pathologies. Estimated of lifetime prevalence of pain and after amputation ranges between 8% and 72%. OBJECTIVE: This narrative review aims to summarize the surgical and non-surgical treatment options for amputation-related neuropathic pain to aid in developing optimized multidisciplinary and multimodal treatment plans that leverage multidisciplinary care. EVIDENCE REVIEW: A search of the English literature using the following keywords was performed: PLP, amputation pain, RLP. Abstract and full-text articles were evaluated for surgical treatments, medical management, regional anesthesia, peripheral block, neuromodulation, spinal cord stimulation, dorsal root ganglia, and peripheral nerve stimulation. FINDINGS: The evidence supporting most if not all interventions for PLP are inconclusive and lack high certainty. Targeted muscle reinnervation and regional peripheral nerve interface are the leading surgical treatment options for reducing neuroma formation and reducing PLP. Non-surgical options include pharmaceutical therapy, regional interventional techniques and behavioral therapies that can benefit certain patients. There is a growing evidence that neuromodulation at the spinal cord or the dorsal root ganglia and/or peripheral nerves can be an adjuvant therapy for PLP. CONCLUSIONS: Multimodal approaches combining pharmacotherapy, surgery and invasive neuromodulation procedures would appear to be the most promising strategy for preventive and treating PLP and RLP. Future efforts should focus on cross-disciplinary education to increase awareness of treatment options exploring best practices for preventing pain at the time of amputation and enhancing treatment of chronic postamputation pain.

ABSTRACT

Infected Ventricular Assist Device (VAD)-associated wounds are common and associated with significant morbidity and mortality. The efficacy of hardware salvage utilizing flaps and negative pressure wound therapy (NPWT) remains understudied. We hypothesized that patients treated with flaps and/or NPWT would have higher hardware salvage rates compared with other surgical management strategies. Methods: A meta-analysis study evaluating VAD-associated wounds was performed following PRISMA guidelines. Primary predictor variables were flap-reconstruction (FR), NPWT, no FR, and infection location (mediastinum versus driveline). Primary outcomes were hardware retention (salvage) versus explantation, infection recurrence, or death. Twenty-nine studies were included. Standard statistical methods included logistic regression analysis. Results: Seventy-four subjects with nonsignificant demographic differences between cohorts were identified. Overall salvage was 59.5% in both driveline and mediastinum cohorts. Overall, NPWT significantly improved salvage compared with no NPWT [77.4% versus 46.5% respectively (P = 0.009)], and FR significantly improved salvage compared with no FR [68.6% versus 39.1% respectively (P = 0.022)]. Logistic regression analysis predicting odds of salvage by FR (area under curve = 0.631) was significantly three times higher (95% CI: 1.2-9.5) and predicting the odds for salvage by NPWT (area under curve = 0.656) was significantly four times higher (95% CI: 1.4-11.1) compared with other treatment. Conclusions: NPWT or flap reconstruction for treatment of threatened VAD hardware was associated with a significantly improved device salvage compared with other surgical strategies. Further study should focus on subgroup analysis of flaps utilized and synergistic treatment benefits.

ABSTRACT

Introduction: Vascularized lymph node transfer (VLNT) restores physiological lymphatic function. Although effective, postoperative impairment of donor-site lymphatic function and iatrogenic lymphedema following lymph node transfer remains a pressing concern. Methods: Prospective analysis of VLNT patients undergoing dual fluorescent tracers-assisted harvest was performed at our institution from September 2013 to April 2022. Reverse lymphatic mapping of the lower extremity was performed with indocyanine green (ICG). Blue dye was utilized in both white light and near-infrared spectra for visualization of donor-site lymphatic structures. Demographics, intraoperative details, and surgical outcomes were recorded. Results: Twenty-five patients were included. Median age was 52.9 years with a body mass index of 29.1 kg/m2 and mean follow-up of 44 months (range 24 to 90 months). Lymphedema stage ranged from Campisi 2 to 4. Inguinal VLNT was performed in 13 patients, and 12 patients received combined VLNT and free flap breast reconstruction. No patients required change in lymph node donor site intraoperatively. All ICG stained nodes were preserved in situ. No cases of iatrogenic lower extremity lymphedema were observed. Postoperative bioimpedance spectroscopy, circumferential, and volumetric measurements of the donor-site limb did not show evidence of subclinical or clinical lymphedema. The donor site healed appropriately in 92% of patients; one patient developed methylene blue-induced skin necrosis. Conclusion: Reverse lymphatic mapping and surgical guidance with dual ICG and blue dye fluorescent tracers provides surgeons with real-time surgical guidance without radioisotope, improves surgical visualization in both white light and near-infrared spectra, and avoids iatrogenic lymphatic dysfunction in the donor limb.

ABSTRACT

SUMMARY: Early identification of surgical indication is critical to optimizing outcomes in orbital floor fracture management. However, identifying those at risk for delayed enophthalmos and requiring subsequent repair has remained a challenge. This study aimed to validate the Orbital Index, a prediction tool using computed tomography to stratify risk for delayed enophthalmos and establish a threshold for repair. The Orbital Index stratifies fractures by size, location, and inferior rectus rounding (a surrogate for fascioligamentous sling disruption) on a scale 0 to 6. A 22-year (1998 to 2020) multi-institution analysis of unilateral isolated orbital floor fractures was performed. Index scores were assigned to each scan, unoperated patients invited for blinded Hertel exophthalmometry assessment, and enophthalmos measurements correlated with Index scores. Interobserver scoring reproducibility was assessed with weighted Cohen kappa. Preintervention and postintervention Likert scale surveys were administered to determine whether this tool improved understanding and communication. The Orbital Index demonstrated high fidelity and interobserver reproducibility and identified a score of four or greater as a surgical threshold. Of 1769 computed tomography scans, 395 met criteria and were included for analysis. Eighty of 395 were managed operatively (operative rate, 20.3 percent). Of 315 patients managed nonoperatively, 41 (13.0 percent) agreed to follow-up evaluation and 28 (68.3 percent) were found to have enophthalmos. Unoperated patients with an Orbital Index score of 4 or higher were more likely to have enophthalmos than those with a score of 3 or less ( p = 0.001). The mean weighted Cohen kappa was 0.73, corroborating reproducibility. Communication ( p = 0.0003) and ability to correctly identify surgical need ( p = 0.01) were improved with use of this tool. The Orbital Index is a reproducible tool to stratify risk for enophthalmos in orbital floor fracture management.

ABSTRACT

BACKGROUND: Corneal neurotization describes reinnervation of the anesthetic or severely hypoesthetic cornea with a healthy local nerve or graft. Preliminary evidence has shown corneal neurotization to improve corneal sensation, visual acuity, and ocular surface health. Factors that improve patient selection and lead to better neurotization outcomes have yet to be elucidated, limiting ability to optimize perioperative decision-making guidelines. METHODS: A systematic review with meta-analysis was performed of the MEDLINE and Embase databases using variations of "corneal," "nerve transfer," "neurotization," and "neurotization." The primary outcomes of interest were corrected visual acuity, NK Mackie stage, and central corneal sensation. Regression analyses were performed to identify the effects of surgical technique, duration of denervation, patient age, and etiology of corneal pathology on neurotization outcomes. RESULTS: Seventeen studies were included. Corneal neurotization resulted in significant improvement in NK Mackie stage (0.84 vs 2.46, P < 0.001), visual acuity (logarithm of minimum angle of resolution scale: 0.98 vs 1.36, P < 0.001), and corneal sensation (44.5 vs 0.7, P < 0.001). Nerve grafting was associated with greater corneal sensation improvement than nerve transfer (47.7 ± 16.0 vs 35.4 ± 18.76, P = 0.03). Denervation duration was predictive of preneurotization visual acuity (logarithm of minimum angle of resolution scale; R2 = 0.25, P = 0.001), and older age (ß = 0.30, P = 0.03) and acquired etiology (ß = 0.30, P = 0.03) were predictive of improved visual acuity. CONCLUSIONS: Corneal neurotization provides significant clinical improvement in visual acuity, NK Mackie staging, and corneal sensation in patients who experience NK. Both nerve grafting and nerve transfer are likely to yield similar levels of benefit and ideally should be performed early to limit denervation time.

ABSTRACT

BACKGROUND: Higher rates of postoperative complication following cleft lip or palate repair have been documented in low resource settings, but their causes remain unclear. This study sought to delineate patient, surgeon, and care environment factors in cleft complications in a low-income country. DESIGN: Prospective outcomes study. SETTING: Comprehensive Cleft Care Center. PATIENTS: Candidate patients presenting for cleft lip or palate repair or revision. INTERVENTIONS: Patient anthropometric, nutritional, environmental and peri- and post-operative care factors were collected. Post-operative evaluation occurred at standard 1-week and 2-month postoperative intervals. MAIN OUTCOME MEASURES: Complication was defined as fistula, dehiscence and/or infection. RESULTS: Among 408 patients enrolled, 380 (93%) underwent surgery, of which 208 (55%) underwent lip repair (124) or revision (84), and 178 (47%) underwent palate repair (96) or revision (82). 322 (85%) were evaluated 1 week and 166 (44%) 2 months postoperatively. 50(16%) complications were identified, including: 25(8%) fistulas, 24(7%) dehiscences, 17(5%) infections. Mid-upper arm circumference (MUAC) ≤12.5 cm was associated with dehiscence after primary lip repair (OR = 28, p = 0.02). Leukocytosis ≥11,500 on pre-operative evaluation was associated with dehiscence (OR = 2.51, p = 0.04) or palate revision fistula (OR = 64, p < 0.001). Surgeons who performed fewer previous-year palate repairs had higher likelihood of palate complications, (OR = 3.03, p = 0.01) although there was no difference in complication rate with years of surgeon experience or duration of surgery. CONCLUSIONS: Multiple patient, surgeon, and perioperative factors are associated with higher rates of complication in a low-resource setting, and are potentially modifiable to reduce complications following cleft surgery.

ABSTRACT

OBJECTIVE: Epidural steroid injections (ESIs) are a commonly used treatment strategy for low back pain and lumbar radiculopathy. However, their cost-effectiveness and ability to mediate long-term quality of life (QOL) improvements is debated. We sought to analyze the cost-effectiveness of lumbar epidural steroid injections (ESIs) compared to medical management alone for patients with lumbar radiculopathy and low back pain. PATIENTS AND METHODS: QOL outcomes were prospectively collected at 3- and 6-months following initial consultation. Metrics included the EuroQol-5 Dimensions (EQ-5D) questionnaire, the Pain Disability Questionnaire (PDQ), the Patient Health Questionnaire (PHQ-9) and the Visual Analogue Scale (VAS). Cost estimations were based on Medicare national payment amounts, median income, and missed workdays. A cost-utility analysis was performed based upon cost estimations and a cost-effectiveness threshold of $100,000/Quality-adjusted life year (QALY). RESULTS: One hundred forty-one patients met our inclusion/exclusion criteria; 89 received ESI and 52 were treated with medical management alone. Both cohorts showed improved EQ-5D scores at 3 months but were similar to one another: ESI (ΔEQ-5D = 0.06; p = 0.03) and medical-alone (ΔEQ-5D = 0.07; p = 0.03). No significant difference was seen between groups for total costs ($2,190 vs. $1,772; p = 0.18) or cost-utility ratios ($38,710/QALY vs. $27,313/QALY; p = 0.73). At both the 3-month and 6-month endpoints, absolute differences in cost-utility was driven by overall costs as opposed to QALY gains. Medical management alone was more cost effective at both points owing to lower expenditures, however these differences were not significant. No benefits were seen in either group on the EQ-5D or any of the patient reported outcomes at the 6-month time point. CONCLUSION: ESIs were not cost-effective at either the 3-month or 6-month follow-up period. At 3 months, ESIs provide similar improvements in QOL outcomes relative to medical management and at similar costs. At 6 months, neither ESIs nor conservative management provide significant improvements in QOL outcomes.

ABSTRACT

BACKGROUND: Transgender patients may seek nonsurgical methods for facial masculinization and feminization as an adjunct or alternative to undergoing surgical procedures. OBJECTIVES: The authors reviewed the existing literature regarding this topic and provided an overview of nonsurgical techniques for facial masculinization and feminization. METHODS: A comprehensive literature search of the PubMed and MedLine databases was conducted for studies published through December 2017 for techniques and outcomes of nonsurgical facial masculinization and feminization. Keywords were used in performing the search. Data on techniques, outcomes, complications, and patient satisfaction were collected. RESULTS: Four articles fit our inclusion criteria. Given the lack of published literature describing facial injectables in transgender patients, data from the literature describing techniques in cisgender patients were utilized to supplement our review. CONCLUSIONS: Facial feminization can be achieved through injectables such as neurotoxin and fillers for lateral brow elevation, lip augmentation, malar augmentation, and improvement of rhytids. Facial masculinization can be achieved with injectables used for genioplasty, jawline augmentation, and supraorbital ridge augmentation. One must develop best practices for these techniques in the transgender patient population and increase awareness regarding nonsurgical options.

ABSTRACT

BACKGROUND: Factors influencing recurrence of ileocecal Crohn's disease (CD) after surgical resection may differ between adolescents and adults. METHODS: CD patients who underwent ileocecectomy were retrospectively divided into pediatric onset (age at diagnosis ≤ 16 years, n = 34) and adult onset (>16, n = 108) patients to evaluate differences in risks of endoscopic and clinical recurrence. RESULTS: In 142 patients, rates of any recurrence, endoscopic recurrence, and clinical recurrence at 5 years were 78%, 88%, and 65%, respectively. Risks of recurrence were similar between groups. Younger patients were more likely to be on immunologics preoperatively and more likely to be started on immunoprophylaxis postoperatively. Immediate postoperative prophylaxis was predictive of delayed clinical recurrence only in the older group. CONCLUSIONS: Despite increased preoperative and postoperative immunoprophylaxis in younger patients, recurrence rates of CD after ileocecectomy do not differ between these groups. Immediate postoperative prophylaxis was predictive of delayed clinical recurrence only in patients with adult onset CD.
