RESUMEN
PURPOSE: This study evaluated pain control after wrist operations using a long-acting local anesthetic, liposomal bupivacaine, compared with the standard local anesthetic, bupivacaine HCl. METHODS: Patients undergoing elective carpometacarpal joint arthroplasty and proximal row carpectomy were eligible. Those meeting inclusion criteria were enrolled before surgery and were randomized to receive an intraoperative injection of liposomal bupivacaine or bupivacaine HCl. Primary outcomes included intraoperative and postoperative opioid requirements and pain levels. On the first 4 postoperative days, phone contact assessed pain level by numeric rating scale, number of opioids taken in each 24-hour period, and efficacy of anesthesia and opioid side effects with overall benefit of analgesia score. RESULTS: Postoperative pain scores for 52 patients measured by numeric rating scale demonstrated that liposomal bupivacaine and bupivacaine HCl were similar for pain control. Pain scores and opioid use were similar during the first 4 postoperative days. Opioid use on day 1 was slightly lower with liposomal bupivacaine. There were no statistically significant differences in any postoperative outcome between groups. CONCLUSIONS: Liposomal bupivacaine and bupivacaine HCl have similar effects in the treatment of early postoperative pain after trapeziometacarpal suspension arthroplasty and proximal row carpectomy. Neither drug demonstrated a clear advantage in this study. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

PURPOSE: Acellular dermal matrices (ADMs) are commonly used for immediate breast reconstruction after skin-sparing mastectomy (SSM). Regnault grades 2 and 3 ptotic breasts feature significant mastectomy flap redundancy that may be incorporated into the reconstruction. This allows surgeons to use patients' de-epithelialized inferior dermal pedicle instead of ADM. METHODS: All consecutive SSM patients with Regnault grade 2 or 3 ptosis who underwent Passot-type immediate breast reconstruction (IBBR) with tissue expanders (TEs) and de-epithelialized inferior dermal pedicle without an ADM were included. Patient data from the electronic medical record, clinical photographs, and a comparative cost analysis of ADM versus additional operative time are provided. RESULTS: Thirty-eight patients with an average age of 52.7 years, weight 210.5 lb, and body mass index of 35.1 kg/m were treated (34 bilateral, 4 unilateral; 72 reconstructed breasts). Average mastectomy specimens weighed 962.8 g. Tissue expanders were filled to 265.0 mL (41.6% capacity) intraoperatively, and final implant volume averaged 710.9 ± 118.5 mL after an average of 628.6 ± 74.1-mL expansion. Operative times for Passot-type IBBR was 124.3 ± 37.7 versus 92.5 ± 27.9 minutes (P = 0.0001) for submuscular TE placement with ADM. The operative technique is described in detail. There were 8 TE explantations (21.1%) included: intractable infection (10.5%; n = 4), symptomatic capsular contracture (7.9%; n = 3), and spontaneous TE deflation (2.6%; n = 1). All but 3 patients (92.1%) successfully completed Passot reconstruction, with 2 patients declining salvage latissimus dorsi flap reconstruction and 1 patient lost to follow-up. Total cost savings in this case series was $89,724 ($2361 ± $3529/case). CONCLUSIONS: Additional prospective comparison studies are needed to determine whether Passot-type IBBR results in higher complication rates than conventional IBBR with ADM in this challenging patient population. Passot-type IBR after SSM is safe, demonstrates acceptable rates of successful breast reconstruction, confers cost savings by obviating the use of ADM, and provides favorable aesthetic results.

BACKGROUND: Expander-to-implant is the most common breast reconstruction procedure in the United States. Irrigation with triple antibiotic solution (TAS), as described by Adams et al in 2006, has become standard of care to lower bacterial bioburden. However, several alternative solutions have been implemented with the literature lacking a consensus regarding use (Plast Reconstr Surg. 2006;117:30-36). OBJECTIVE: We distributed a peer-reviewed survey among a cohort of American Society of Plastic Surgery (ASPS) members to assess pocket irrigation technique during implant-based reconstructive surgery. We then conducted a pilot in vitro study to determine antibacterial efficacy of the most preferred irrigation at preferred dwell times against select bacterial species linked to breast pocket contamination during reconstructive implant-based surgery. METHODS: The survey was distributed a total of 3 times to a random cohort of 2488 ASPS members in January 2018. During in vitro studies, pure cultures of common breast flora were exposed to TAS versus saline control at 1, 2, and 5 minutes in a simulated in vivo cavity. Viable plate counts were used to assess cell viability. RESULTS: The response rate was above the ASPS survey average at 16% (n = 407). The population reflected a cross-section of practice types and experience levels. Triple antibiotic solution without Betadine was the favored irrigation at 41%, with 73% of its users preferring dwell times of 2 minutes or less. Over 30 distinct breast pocket irrigation solutions were identified. Bacteria added to the in vivo cavity survived a 2-minute dwell time with TAS as follows: 51% Staphylococcus epidermidis, 69% Escherichia coli, 88% Enterococcus faecalis, 88% Pseudomonas aeruginosa, and 98% Acinetobacter baumannii. CONCLUSION: Our survey data demonstrate significant variability in practice and lack of consensus among ASPS members regarding antimicrobial irrigation during reconstructive breast surgery. Our in vitro data underscores the importance of relating clinical practices with laboratory studies of microorganisms potentially linked to breast pocket contamination and suggests that TAS requires either dwell times greater than 5 minutes and/or the inclusion of efficacious antimicrobial agents (eg, Betadine). This finding has the potential to impact antimicrobial pocket irrigation and technique during breast reconstruction.

PURPOSE: The skin paddle of the latissimus dorsi flap is typically inset horizontally (HILD) in breast reconstruction. We describe our experience with the vertical inset of the latissimus dorsi (VILD) and its aesthetic benefit. METHODS: We performed a case-control study comparing the most recent cases of both VILD and HILD. Scar, as seen on anterior-posterior photographs, was digitally measured and compared from 3 clinically relevant areas: (1) all visible scarring ("mirror view"), (2) scarring above the nipple ("self-view"), and (3) scarring above or medial to the nipple ("social view"). Demographics and outcomes were statistically compared. EXPERIENCE/RESULTS: Fifty of the most recent patients receiving HILD or VILD were selected for each group. Average patient age was 55.6 and 51.6 years (P = 0.32), and average follow-up was 531.6 and 606.7 days (P = 0.20), respectively. The VILD scar-length ratios were decreased by 17% in the mirror view (P ≤ 0.01), 37% in the self-view (P ≤ 0.01), and 37% in the social view (P ≤ 0.01). There were no statistically significant differences between groups regarding smoking (P = 0.75), diabetes (P = 0.70), body mass index (P = 0.74), seroma (P = 0.46), infection (P = 1.0), or flap necrosis (P = 0.70). CONCLUSIONS: The VILD is safe and reliable. Measurements from anterior-posterior photographs illustrate statistically significant decreases in overall scar burden (mirror view) and statistically significant reductions in the highly visible self-view and social view. Our study is the first to quantify a reduction in scar burden by using VILD technique.

PURPOSE: Implant-based breast reconstruction is fraught with complications related to seroma formation. Soft tissue stabilization with progressive tension closure (PTC) has been shown to decrease seroma formation after various procedures but is less suitable for mastectomy flap stabilization. We evaluate the incidence of seroma in breast reconstruction using bioabsorbable barbed ribbon devices (BRDs) as a novel approach to PTC. METHODS: We performed a retrospective review of all patients whose mastectomy flaps were stabilized with BRDs. These patients were compared with consecutive patients who underwent mastectomy and reconstruction without progressive tension flap stabilization. Patient demographics and outcomes were recorded, including comorbidities, complications, presence of seroma, and total drain days. RESULTS: In the BRD-PTC group, there were 36 breasts compared with 56 in the nonstabilized control group. There were no significant differences in rate of tobacco use, age, or body mass index. We identified 11 seromas in the control group (19.6%) and none in the intervention group (P = 0.05). In the PTC group, drains were removed an average of 5 days sooner than those in controls (P = 0.006). CONCLUSION: Progressive tension stabilization of mastectomy flaps with BRD significantly reduces seroma formation and the duration for which closed suction drainage is required.

BACKGROUND: With the increasing popularity of fat grafting over the past decade, the techniques for harvest, processing and preparation, and transfer of the fat cells have evolved to improve efficiency and consistency. The REVOLVE System is a fat processing device used in autologous fat grafting which eliminates much of the specialized equipment as well as the labor intensive and time consuming efforts of the original Coleman technique of fat processing. This retrospective study evaluates the economics of fat grafting, comparing traditional Coleman processing to the REVOLVE System. METHODS: From June 2013 through December 2013, 88 fat grafting cases by a single-surgeon were reviewed. Timed procedures using either the REVOLVE System or Coleman technique were extracted from the group. Data including fat grafting procedure time, harvested volume, harvest and recipient sites, and concurrent procedures were gathered. Cost and utilization assessments were performed comparing the economics between the groups using standard values of operating room costs provided by the study hospital. RESULTS: Thirty-seven patients with timed procedures were identified, 13 of which were Coleman technique patients and twenty-four (24) were REVOLVE System patients. The average rate of fat transfer was 1.77 mL/minute for the Coleman technique and 4.69 mL/minute for the REVOLVE System, which was a statistically significant difference (P < 0.0001) between the 2 groups. Cost analysis comparing the REVOLVE System and Coleman techniques demonstrates a dramatic divergence in the price per mL of transferred fat at 75 mL when using the previously calculated rates for each group. CONCLUSIONS: This single surgeon's experience with the REVOLVE System for fat processing establishes economic support for its use in specific high-volume fat grafting cases. Cost analysis comparing the REVOLVE System and Coleman techniques suggests that in cases of planned fat transfer of 75 mL or more, using the REVOLVE System for fat processing is more economically beneficial. This study may serve as a guide to plastic surgeons in deciding which cases might be appropriate for the use of the REVOLVE System and is the first report comparing economics of fat grafting with the traditional Coleman technique and the REVOLVE System.

BACKGROUND: Autologous tissue flaps play an integral part in breast reconstruction. The latissimus dorsi myocutaneous flap is an effective and aesthetic method of immediate breast reconstruction, although a high rate of donor site seroma formation has plagued this procedure. Many techniques to reduce donor site seromas have been undertaken. This study evaluates the effect of progressive-tension closure (PTC) on postoperative seroma. METHODS: This is a retrospective cohort study of 100 breasts reconstructed using a traditional closure versus PTC of the donor site. Outcomes collected include patient age, date of surgery, side of surgery, body mass index (BMI), smoking status, diabetes diagnosis, number of days the initial operative drain was present, seroma occurrence, seroma aspirations, seroma catheters placed, and operative interventions. RESULTS: The PTC technique significantly decreased seroma formation, with 40% of the traditional closure sites developing seromas and only 14% in the PTC group (P = 0.0078). The mean number of days the postoperative drain remained was significantly reduced with the PTC technique, just 16.6 days compared to 27.8 days (P < 0.0001). Of the seromas which did develop, the PTC group had significantly fewer aspirations (38.9% vs 14%, P = 0.014), drains placed (15.8% vs 4.6%, P < 0.0001), and operative interventions (7% vs 0%, P < 0.0001). There was no significant difference in mean patient age (54.1, 52.4) or body mass index (28.1, 27.3) between the groups. CONCLUSIONS: The PTC technique of closing latissimus dorsi donor sites significantly decreases seroma formation, number of days a drain is present, and postoperative interventions. This decreases the time and resources devoted to addressing seromas.

Different surgical incisions have been proposed for skin-sparing mastectomy in an attempt to better disguise the remaining scar. These techniques are more hidden than the Stewart incision but can still leave scars in visible places and can restrict the natural shape of the upper pole. They can also add complexity and time to the mastectomy, requiring extensive retraction that could damage the salvaged skin flaps to perform an adequate mastectomy. We present a circumvertical mastectomy incision technique, which limits the mastectomy scar to the inferior pole, provides natural lateral contour, superior pole fullness, and contributes to a more youthful breast projection. Between November 2011 and November 2012, 51 women underwent circumvertical AlloDerm/tissue expansion reconstruction at our institution by a single surgeon. The reconstruction was bilateral in 30 patients and unilateral in 21 patients for a total of 81 breasts. Of the 81 reconstructed breasts, 5 patients went on to require a latissimus dorsi flap for definitive reconstruction and 3 failed breast reconstruction for a completion rate of 96%. The goal of creating breast reconstruction results comparable to those of cosmetic breast surgery is becoming a reality. Circumvertical incision is a technique that can prevent visible upper hemispheric breast scarring, limit upper pole constriction by scar placement, and preserves or restores breast projection. Following the principles of aesthetic breast surgery and repositioning the mastectomy scar, one can reconstruct a breast with a more disguised scar, which can be hidden from the patient's downward gaze.

Tissue expander (TE)/acellular dermal matrix (ADM)-based breast reconstruction used in immediate postmastectomy breast reconstruction, although a popular technique, is not without complications.Although seroma formation is recognized and reported in the literature as a complication, little information addresses seroma(s) management. We conducted a retrospective review of 100 consecutive TE/ADM immediate reconstructions during a 2-year period, performed by a single surgeon. Data collection included patient demographics, adjuvant therapy, initial TE fill volume, time to completion of expansion, seroma formation, management of seroma, and wound complications, up to the time of definitive implant exchange. From December 2009 to December 2011, 67 patients (100 reconstructions) underwent TE/ADM immediate breast reconstruction. Thirty-one reconstructions were identified having clinically significant seroma(s). Eighteen of the reconstructions required multiple drainage procedures. With these data, a 3-group classification system was created based on the number of aspirations. In review of the 3 groups, 71% of group III required either Seroma-Cath or operative drainage beyond simple aspiration(s). Of the 100 reconstructions, 3 (3%) ended in TE explantation. Only 1 (3%) TE explantation, interestingly from group I, was attributable to seroma formation. Using the data, we devised a management strategy emphasizing attentiveness to seroma formation, recognition, and treatment. Seroma formation is a known entity linked to complications in TE/ADM reconstructive course. A seroma classification system and treatment algorithm is offered to minimize abandonment of the reconstruction and optimize outcomes.

Background: The etiology of recurrent carpal tunnel syndrome (CTS) is unclear, and outcomes following secondary surgery in this demographic have been poorer than primary surgery. Fibrosis and hypertrophy have been identified in the flexor tenosynovium in these patients. The authors use flexor tenosynovectomy (FTS) for recurrent CTS after primary carpal tunnel release and present a review of these patients. Methods: A retrospective chart review was performed of 108 cases of FTS for recurrent CTS from 1995 to 2015 by 4 attending surgeons at one institution. Demographic information, symptoms, and outcomes were among the data recorded. A phone survey was conducted on available patients where the shortened version of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH) and satisfaction were assessed. Results: Average office follow-up was 12 months. Average age was 57.5 years. A total of 104 (96%) reported symptom improvement and 48 (44%) reported complete symptom resolution. Forty patients were available for long-term follow-up at an average 6.75 years postoperatively via phone interview. Average QuickDASH score was 31.2 in these patients. Thirty-six (90%) of 40 patients were initially satisfied at last office visit, and 31 (78%) of 40 were satisfied at average 6.9 years, a maintenance of satisfaction of 86%. Satisfied patients were older (58 years) than unsatisfied patients (51 years). Conclusion: Both long-term satisfaction and QuickDASH scores in our cohort are consistent with or better than published results from nerve-shielding procedures. The authors believe a decrease in both carpal tunnel volume and potential adhesions of fibrotic or inflammatory synovium contributes to the benefits of this procedure. This remains our procedure of choice for recurrent CTS.

Breast augmentation is among the most common procedures performed in the United States. Though bacterial contamination of breast prostheses is associated with adverse sequelae, there are no universally accepted guidelines and limited best practice recommendations for antimicrobial breast pocket irrigation. We designed a survey to identify pocket irrigation preferences and antimicrobial techniques during implant-based breast augmentation among American Society of Plastic Surgeons (ASPS) members. METHODS: In January 2018, a random cohort of 2,488 ASPS members was surveyed. Questions queried breast pocket irrigation methods and surgical techniques including implant placement, incision location, and implant soaking agents. An extensive literature review of breast pocket irrigation practices was completed and used as a basis for the survey. RESULTS: The survey response rate was above the ASPS average at 16% (n = 407). Respondents preferred an inframammary incision (90%) and submuscular implant placement (92%). Triple antibiotic solution (TAS) and TAS + Betadine ± Bacitracin were preferred by 61% and Betadine variants by 11%. Preferred dwell times stratified to 30 seconds (39%), 1 minute (18%), 2-5 minutes (21%), and >5 minutes (22%). Among those employing a TAS variant, 53% preferred a suboptimal dwell time of ≤1 minute. Prostheses were soaked in TAS (42%), TAS + Betadine ± Bacitracin (15%), a Betadine variant (12%), or other (31%). CONCLUSIONS: Periprosthetic bacterial contamination leads to comorbidity following breast augmentation. Our results reveal significant variability regarding breast pocket irrigation techniques among ASPS members during cosmetic breast augmentation. These data suggest the need for best practice guidelines regarding breast pocket irrigation and implant soaking agents.
RESUMEN
OBJECTIVE: Resident clinics (RCs) are intended to catalyze the achievement of educational milestones through progressively autonomous patient care. However, few studies quantify their effect on competency-based surgical education, and no previous publications focus on hand surgery RCs (HRCs). We demonstrate the achievement of progressive surgical autonomy in an HRC model. DESIGN: A retrospective review of all patients seen in a weekly half-day HRC from October 2010 to October 2015 was conducted. Investigators compiled data on patient demographics, provider encounters, operational statistics, operative details, and dictated surgical autonomy on an ascending 5 point scoring system. SETTING: A tertiary hand surgery referral center. RESULTS: A total of 2295 HRC patients were evaluated during the study period in 5173 clinic visits. There was an average of 22.6 patients per clinic, including 9.0 new patients with 6.5 emergency room referrals. Totally, 825 operations were performed by 39 residents. Trainee autonomy averaged 2.1/5 (standard deviation [SD] = 1.2), 3.4/5 (SD = 1.3), 2.1/5 (SD = 1.3), 3.4/5 (SD = 1.2), 3.2/5 (SD = 1.5), 3.5/5 (SD = 1.5), 4.0/5 (SD = 1.2), 4.1/5 (SD = 1.2), in postgraduate years 1 to 8, respectively. Linear mixed model analysis demonstrated training level significantly effected operative autonomy (p = 0.0001). Continuity of care was maintained in 79.3% of cases, and patients were followed an average of 3.9 clinic encounters over 12.4 weeks. CONCLUSIONS: Our HRC appears to enable surgical trainees to practice supervised autonomous surgical care and provide a forum in which to observe progressive operative competency achievement during hand surgery training. Future studies comparing HRC models to non-RC models will be required to further define quality-of-care delivery within RCs.

BACKGROUND: Resident clinics are thought to catalyze educational milestone achievement through opportunities for progressively autonomous surgical care, but studies are lacking for general plastic surgery resident clinics (PSRCs). We demonstrate the achievement of increased surgical autonomy and continuity of care in a PSRC. METHODS: A retrospective review of all patients seen in a PSRC from October 1, 2010, to October 1, 2015, was conducted. Our PSRC is supervised by faculty plastic surgery attendings, though primarily run by chief residents in an accredited independent plastic surgery training program. Surgical autonomy was scored on a 5-point scale based on dictated operative reports. Graduated chief residents were additionally surveyed by anonymous online survey. RESULTS: Thousand one hundred forty-four patients were seen in 3,390 clinic visits. Six hundred fifty-three operations were performed by 23 total residents, including 10 graduating chiefs. Senior resident autonomy averaged 3.5/5 (SD = 1.5), 3.6/5 (SD = 1.5), to 3.8/5 (SD = 1.3) in postgraduate years 6, 7, and 8, respectively. A linear mixed model analysis demonstrated that training level had a significant impact on operative autonomy when comparing postgraduate years 6 and 8 (P = 0.026). Graduated residents' survey responses (N = 10; 100% response rate) regarded PSRC as valuable for surgical experience (4.1/5), operative autonomy (4.4/5), medical knowledge development (4.7/5), and the practice of Accreditation Council of Graduate Medical Education core competencies (4.3/5). Preoperative or postoperative continuity of care was maintained in 93.5% of cases. CONCLUSION: The achievement of progressive surgical autonomy may be demonstrated within a PSRC model.
