RESUMEN

The free radial forearm flap is the gold standard technique for transgender phalloplasty due to superior complication rates compared to other methods. However, reconstruction of the urinary tract, including urethral lengthening and creation of a pars pendula urethra within the flap, carries a high rate of complications. The risk of complications and a lack of desire for standing urination are reasons patients elect for single-tube phalloplasty. However, to date, single-tube phalloplasties lack creation of a urinary meatus, which affects the aesthetics of the reconstruction. The purpose of this report is to describe a technique for creating an aesthetic urinary meatus in single-tube phalloplasty. We herein describe the technique in the use of two healthy transgender males (ages 31 and 39). Both patients did not desire micturition through the neophallus, but still desired the appearance of a meatus at the tip of the neophallus. Single-tube radial forearm phalloplasty was performed for both patients. The radial forearm flaps for each patient were 14 × 15 cm. Meatoplasty was performed at the time of flap elevation utilizing an intact 1 × 4 cm intact strip of ulnar sided skin during flap tubularization. This strip of skin was then invaginated to create a neomeatal pouch. The postoperative course was uncomplicated for both patients following at 5-day hospital stay for flap monitoring. Follow up time was 7 and 8 months. The neomeatal pouch persisted in both patients and the patients were satisfied with the appearance of the tips of the neophalluses.

RESUMEN

ABSTRACT: There are 2 to 5 million laparotomies performed in the United States annually. Of these, 250,000 to 350,000 will undergo a ventral hernia repair. Repairs are often complicated by recurrence and infection. These risks are significantly increased in previously infected repairs, with reported recurrence rates varying from 17% to 28% after repair of infected ventral hernias, double the rates reported for first-time uninfected repairs. We describe here a novel treatment strategy involving the creation then use of bilateral prelaminated permanent mesh-reinforced tensor fascia latae flaps for abdominal wall reconstruction in patients who have recurrent ventral hernias and had undergone previous repairs complicated by infection. Previous repairs included anterior components separation, thereby making subsequent fascial release techniques and achievement of a reinforced repair extremely unlikely. Three patients were treated by a single surgeon using this 2-stage technique. There have been no incidences of recurrence and no infections after 2 to 10 years. In these patients, the only conventional option would have been a bridged repair with absorbable mesh. Combining the advantages of permanent mesh and well-vascularized autologous tissue optimizes the repair's tensile strength while mitigating the chance of recurrent infection associated with the use of permanent mesh. We propose that this strategy may be an appropriate treatment option for patients with recurrent ventral hernias that have not responded to other conventional modalities of treatment.

RESUMEN

BACKGROUND: Autologous fat is a safe and effective soft tissue filler. Recent evidence also suggests improved wound healing and immune modulation with fat grafting. OBJECTIVES: The aim of this study was to describe a novel technique utilizing fat grafting during primary open rhinoplasty. We hypothesize a more rapid resolution of bruising and edema. METHODS: Patients who underwent rhinoplasty were reviewed and compared by presence or absence of concurrent fat grafting. Three-dimensional images were analyzed employing Mirror (Vectra, Canfield Scientific, NJ). Ecchymoses were outlined utilizing a magnetic lasso followed by an area measurement. Volumetric edema measurements were also taken and assessed. Edema and ecchymosis were measured at 2 and 6 weeks postoperatively. Statistical significance was defined as P < 0.05. RESULTS: Sixty-two patients were included. Thirty-three patients (53.2%) received autologous fat grafting and 29 (46.8%) did not. Age, gender, surgical approach, and osteotomy distribution were similar between the groups. The fat grafted group showed 7.29 cm2 fewer ecchymoses (P < 0.001) and 0.73 cc less edema (P = 0.68) in the early postoperative interval. Six weeks postoperatively, the fat grafted group showed 1 cc less edema (P = 0.36) with negligible differences in bruising. CONCLUSIONS: Autologous fat grafting is a useful adjunct to rhinoplasty and is associated with significantly fewer ecchymoses in the acute postoperative period.

RESUMEN

SUMMARY: Pain after amputation is often managed by target muscle reinnervation (TMR) with the added benefit that TMR also provides improved myoelectric terminal device control. However, as TMR takes several months for the recipient muscles to reliably reinnervate, this technique does not address pain within the subacute postoperative period during which pain chronification, sensitization, and opioid dependence and misuse may occur. Cryoneurolysis, described herein, uses focused, extreme temperatures to essentially "freeze" the nerve, blocking nociception, and improving pain in treated nerves potentially reducing the chances of pain chronification, sensitization, and substance dependence or abuse.

RESUMEN

Severe open lower extremity trauma requires debridement to remove contamination and devitalized tissues. Aggressive debridement should be balanced with preservation of viable tissue. These often damaged but preserved viable tissues are "spare parts" that augment the options available for reconstruction. The long-term goal of reconstruction should be functional limb restoration and optimization. Injury patterns, levels, and patient factors will determine whether this endeavor is better accomplished with limb salvage or amputation. This article reviews the rationale and strategies for preserving spare parts throughout debridement and then incorporating them as opportunistic grafts in the ultimate reconstruction to facilitate healing and maximize extremity function. Level of Evidence: 5.

RESUMEN

BACKGROUND: While synthetic prosthetics have essentially become mandatory for hernia repair, mesh-induced chronic inflammation and scarring can lead to chronic pain and limited mobility. Mesh propensity to induce such adverse effects is likely related to the prosthetic's material, weight, and/or pore size. We aimed to compare histopathologic responses to various synthetic meshes after short- and long-term implantations in mice. MATERIAL AND METHODS: Samples of macroporous polyester (Parietex [PX]), heavyweight microporous polypropylene (Trelex[TX]), midweight microporous polypropylene (ProLite[PL]), lightweight macroporous polypropylene (Ultrapro[UP]), and expanded polytetrafluoroethylene (DualMesh[DM]) were implanted subcutaneously in mice. Four and 12 wk post-implantation, meshes were assessed for inflammation, foreign body reaction (FBR), and fibrosis. RESULTS: All meshes induced varying levels of inflammatory responses. PX induced the greatest inflammatory response and marked FBR. DM induced moderate FBR and a strong fibrotic response with mesh encapsulation at 12 wk. UP and PL had the lowest FBR, however, UP induced a significant chronic inflammatory response. Although inflammation decreased slightly for TX, marked FBR was present throughout the study. Of the three polypropylene meshes, fibrosis was greatest for TX and slightly reduced for PL and UP. For UP and PL, there was limited fibrosis within each mesh pore. CONCLUSION: Polyester mesh induced the greatest FBR and lasting chronic inflammatory response. Likewise, marked fibrosis and encapsulation was seen surrounding ePTFE. Heavier polypropylene meshes displayed greater early and persistent fibrosis; the reduced-weight polypropylene meshes were associated with the least amount of fibrosis. Mesh pore size was inversely proportional to bridging fibrosis. Moreover, reduced-weight polypropylene meshes demonstrated the smallest FBR throughout the study. Overall, we demonstrated that macroporous, reduced-weight polypropylene mesh exhibited the highest degree of biocompatibility at sites of mesh implantation.

RESUMEN

Composite injuries to the lower extremity from etiologies including trauma and infection present a complex dilemma for the reconstructive surgeon, and require multidisciplinary collaboration amongst plastic, vascular, and orthopaedic surgical specialties. Here we present our algorithm for lower-extremity reconstructive management, refined over the last decades to provide an optimized outcome for our patients. Reconstruction is predicated on the establishment of a clean and living wound, where quality of the wound-bed is prioritized over timing to soft-tissue coverage. Once established, soft-tissues and fractures are provisionally stabilized; our preference for definitive coverage is for microvascular free-tissue, due to the paucity of healthy soft-tissue available at the injury, and ability to avoid the zone of injury for microvascular anastomosis. Finally, definitive bony reconstruction is dictated by the length and location of long-bone defect, with a preference to utilize bone transport for defects longer than 5 cm.

RESUMEN

BACKGROUND: Hospital-acquired pressure ulcers (HAPUs) are largely preventable yet still common occurrences in hospitals. The purpose of the current study is to determine how data from the electronic medical record can be used to better understand and predict HAPU formation over the course of a hospital admission. METHODS: A case-control study on HAPUs was performed over an 8-month period at Yale New Haven Hospital. A Cox regression analysis model analyzed the impact of multiple factors on HAPU development including friction and shear, among other Braden score components. A receiver operating characteristic curve was calculated to determine the sensitivity and specificity of changes in these factors in predicting HAPU development. RESULTS: On a sample of 8,790 admissions, HAPU incidence was 4.2% over the study period (6.3% per annum). The average hospital day for HAPU development was day 15.6 (± 19.3). The Cox regression analysis demonstrated that the volatility of the friction and shear component of Braden scores had a risk ratio of 28.6 (P < 0.01; CI, 14.5-56.4). Volatility in the friction and shear component was the most predictive factor with a high receiver operating characteristic curve area of 0.865 (CI, 0.847-0.882). CONCLUSIONS: Volatility of the friction and shear component of Braden scores appears to be the most significant factor preceding HAPU development at Yale New Haven Hospital. Efforts to place more focus on identifying and reducing volatility of this factor may help decrease HAPU risk for future patients.

RESUMEN

Medical curricula are continually evolving and increasing clinical relevance. Gross anatomy educators have tested innovations to improve the clinical potency of anatomic dissection and found that clinical correlations are an effective method to accomplish this goal. Recently, surgical educators defined a role for laparoscopy in teaching anatomy. We aimed to expand this role by using surgical educators to create clinical correlates between gross anatomy and clinical surgery. We held supplements to traditional anatomy open dissection for medical students, including viewing prerecorded operative footage and live laparoscopic dissection performed on cadavers. The main outcome measures were assessed through pre- and postsession surveys. Greater than 75 per cent of students found the demonstrations highly valuable, and students perceived a significant increase in their understanding of abdominopelvic anatomy (P < 0.01). Additionally, 62 per cent of students with previous interest in surgery and 10 per cent of students without previous interest in surgery reported increased interest in pursuing surgical careers. Our demonstrations advance the use of minimally invasive surgical technology to teach gross anatomy. Live laparoscopic demonstrations augment traditional anatomic instruction by reinforcing the clinical relevance of abdominopelvic anatomy. Additionally, laparoscopic demonstrations generate interest in surgery that would otherwise be absent in the preclinical years.

RESUMEN

Jejunal diverticulitis is a rare clinical entity with a high degree of clinical variability and nonspecific radiographic findings, making it a diagnostic challenge. Definitive diagnosis is typically not made until surgery is undertaken, most commonly by laparotomy. We present a case of laparoscopic diagnosis and management of an elderly man with an acute jejunal diverticulitis. The use of a laparoscopic approach provided for an effective therapy without any perioperative morbidity. Clear visualization of the extent of the disease allowed us to avoid intestinal resections. Laparoscopic washout and postoperative bowel rest and intravenous antibiotics seem to be sufficient for acute nonperforated jejunal diverticulitis. Despite his advanced age, our management allowed for a speedy and uneventful recovery in our patient. As a result, we advocate that diagnostic laparoscopy should be considered in most cases of suspected acute jejunal diverticulitis. In addition to facilitating a correct diagnosis, laparoscopic exploration and washout may provide effective management of the acute attack while obviating the need for major abdominal explorations and resections.
