Micro-Coring: A Novel Approach to Perioral Rejuvenation.

BACKGROUND: A long philtrum and poor perioral skin quality are stigmata of the aging face. Micro-coring is a novel technology that allows for scarless skin removal. OBJECTIVES: This study aimed to determine if micro-coring can shorten the philtrum and improve perioral skin quality. METHODS: A retrospective cohort study was performed on subjects who underwent facelift with perioral micro-coring and age/BMI-matched control patients who underwent facelift alone. Preoperative and postoperative three-dimensional facial imaging was performed. Standard perioral distances and percent change were calculated. Perioral skin quality was evaluated by blinded raters using the Scientific Assessment Scale of Skin Quality (SASSQ) and Global Aesthetic Improvement Scale (GAIS). RESULTS: Thirteen subjects and thirteen controls were included with a mean follow-up of 8.9 months (range 3.0-21.5). Subjects had significantly shorter mean philtral length postoperatively as compared to preoperatively, with an average decrease of 6.18% (±2.25%) (p<0.05). Controls did not experience significant changes in philtrum length (p>0.05). Postoperative philtrum length was significantly shorter in subjects as compared to controls (p<0.05). There were no significant changes in other perioral measurements. Perioral skin elasticity and wrinkles significantly improved in subjects as compared to controls and subjects had significantly greater GAIS scores (p<0.05). CONCLUSIONS: Micro-coring can achieve perioral rejuvenation through measurable shortening of the philtrum and observable improvement in skin quality. Non-surgical techniques continue to find new ways to achieve aesthetic goals without significant recovery or scarring and offer value to patients and clinicians.

Does Concomitant Umbilical Hernia Repair Increase the Risk of Complications in Abdominoplasty? A Propensity Score Matched Analysis.

BACKGROUND: Patients seeking cosmetic abdominoplasty often have umbilical hernias. Optimal management and safety of concomitant umbilical hernia repair with abdominoplasty is not well described. OBJECTIVES: The goal of this study was to compare complication rates following abdominoplasty with or without umbilical hernia repair. METHODS: A retrospective propensity score matched cohort study of patients who underwent an abdominoplasty at Massachusetts General Hospital was performed. Direct umbilical hernia repair was performed by making a fascial slit inferior or superior to the umbilical stalk. The fascial edges were approximated with up to three 0-Ethibond sutures (Ethicon, Raritan, NJ) from the preperitoneal or peritoneal space. Propensity score matching was used to adjust for confounding variables. RESULTS: The authors identified 231 patients with a mean [standard deviation] age of 46.7 [9.7] years and a mean BMI of 25.9 [4.4] kg/m2. Nine (3.9%) had diabetes, 8 (3.5%) were active smokers, and the median number of previous pregnancies was 2. In total, 223 (96%) had a traditional abdominoplasty, whereas 8 (3.5%) underwent a fleur-de-lys approach. Liposuction was performed on 90%, and 45.4% underwent simultaneous breast or body contouring surgery. The overall complication rate was 6.9%. Propensity scores matched 61 pairs in each group (n = 122) with closely aligned covariates. There was no significant difference in total complication rates between abdominoplasty alone vs abdominoplasty with hernia repair. There were no cases of skin necrosis or umbilical necrosis in either group. CONCLUSIONS: Performing umbilical hernia repair with abdominoplasty is safe when utilizing the technique reported in this series.

Outcomes following replantation surgery.

The ability to perform surgical replantation of individual digits and limbs can provide substantial functional improvement for patients who sustain devastating upper extremity injuries. Defining success in replantation surgery extends beyond the acute period and the binary metrics of survival or loss of the replanted part to include the long-term overall functional outcomes. Functional outcomes include both objective clinical evaluation and patient-reported outcomes. There has been significant variation in the way outcomes following replantation are measured, which inherently leads to heterogeneity in the reported outcome data. Given the variability among outcome measures, we aim to explore the outcomes of replantation surgery, particularly clinical evaluation and patient-reported functional outcomes following replantation.

Patient-reported Outcomes at 6 to 12 Months Among Survivors of Firearm Injury in the United States.

OBJECTIVE: Assess outcomes in survivors of firearm injuries after 6 to 12 months and compared them with a similarly injured trauma population. BACKGROUND: For every individual in the United States who died of a firearm injury in 2017, three survived, living with the burden of their injury. Current firearm research largely focuses on mortality and short-term health outcomes, while neglecting the long-term consequences. METHODS: We contacted adult patients with a moderate-to-severe injury from a firearm or motor vehicle crash (MVC) treated at 3 level I trauma centers in Boston between 2015 and 2018. Patients were contacted 6 to 12 months postinjury to measure: presence of daily pain; screening for post-traumatic stress disorder (PTSD); new functional limitations; return to work; and physical and mental health-related quality of life. We matched each firearm injury patient to MVC patients using Coarsened Exact Matching. Adjusted Generalized Linear Models were used to compare matched patients. RESULTS: Of 177 eligible firearm injury survivors, 100 were successfully contacted and 63 completed the study. Among them, 67.7% reported daily pain, 53.2% screened positive for PTSD, 38.7% reported a new functional limitation in an activity of daily living, and 59.1% have not returned to work. Compared with population norms, overall physical and mental health-related quality of life was significantly reduced among firearm injury survivors. Compared with matched MVC survivors (n = 255), firearm injury survivors were significantly more likely to have daily pain [adjusted odds ratio (OR) 2.30, 95% confidence interval (CI) 1.08-4.87], to screen positive for PTSD (adjusted OR 3.06, 95% CI 1.42-6.58), and had significantly worse physical and mental health-related quality of life. CONCLUSIONS: This study highlights the need for targeted long-term follow-up care, physical rehabilitation, mental health screening, and interventions for survivors of firearm violence.

Long-Term Functional Outcomes of Trauma Patients With Facial Injuries.

BACKGROUND: Facial trauma can have long-lasting consequences on an individual's physical, mental, and social well-being. The authors sought to assess the long-term outcomes of patients with facial injuries. METHODS: This is a prospective multicenter cohort study of patients with face abbreviated injury scores ≥1 within the Functional Outcomes and Recovery after Trauma Emergencies registry. The Functional Outcomes and Recovery after Trauma Emergencies registry collects patient-reported outcomes data for patients with moderate-severe trauma 6 to 12 months after injury. Outcomes variables included general and trauma-specific quality of life, functional limitations, screening for post-traumatic stress disorder, and postdischarge healthcare utilization. RESULTS: A total of 188 patients with facial trauma were included: 69.1% had an isolated face and/or head injury and 30.9% had a face and/or head injuries as a part of polytrauma injury. After discharge, 11.7% of patients visited the emergency room, and 13.3% were re-admitted to the hospital. Additionally, 36% of patients suffered from functional limitations and 17% of patients developed post-traumatic stress disorder. A total of 34.3% patients reported that their injury scars bothered them, and 49.4% reported that their injuries were hard to deal with emotionally. CONCLUSIONS: Patients who sustain facial trauma suffer significant long-term health-related quality of life consequences stemming from their injuries.

Laparoscopic Segment 1 with Partial IVC Resection in Advanced Cirrhosis: How to Do It Safely.

BACKGROUND: Laparoscopic versus open hepatocellular carcinoma (HCC) resection reduces morbidity without a compromise in oncologic safety.1-4 Moreover, in the subgroup of cirrhotic patients, a decreased risk of prolonged postoperative ascites and liver decompensation has been reported.5-7 METHODS: A 54-year-old homeless, deaf male with chronic alcoholism, hepatitis C, and advanced cirrhosis was referred with a caudate tumor from a critical access hospital. Imaging showed a 3.6-cm HCC in the caudate lobe compressing the inferior vena cava (IVC). With the patient in reversed, modified French position, the liver was mobilized, and the hepatocaval space dissected. Portal and short hepatic vein branches were individually controlled, and the caudate lobe was dissected off the IVC. At the superior portion of the Spiegel process, the tumor was inseparable from the IVC, necessitating en bloc segment 1 with partial IVC resection. The IVC was reconstructed laparoscopically following a preplanned approach. The pathology report confirmed R0 resection of a moderately differentiated hepatocellular carcinoma without microvascular or perineural invasion (pT1bN0M0). CONCLUSION: Laparoscopic caudate lobectomy for cirrhotic patients with partial IVC resection is technically demanding. It therefore requires a strategic and preplanned approach with dedicated instrumentation and laparoscopic skills available. Although the caudal view along the axis of the IVC facilitates dissection, a laparoscopic approach necessitates particular attention to central venous pressure management (intravenous fluid and respiratory tidal volume), meticulous control of portal and short hepatic vein branches, and availability of specialty laparoscopic instrumentation to ensure procedural safety.

A retrospective cohort study of endoscopic therapy and esophagectomy for stage 1 esophageal cancer: less is more.

BACKGROUND AND AIMS: Current guidelines recommend consideration of endoscopic therapy (ET) when treating select stage I esophageal cancers. The proportion of esophageal cancers treated with ET compared with esophagectomy has increased over time. Overall and cancer-specific survival have not been shown to be superior with ET in prior population-based studies. We thus evaluated cancer-specific survival comparing patients treated with ET and esophagectomy. METHODS: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results database from 2004 to 2015 of patients with node-negative, superficial (T1a/T1b), esophageal cancer treated with ET or esophagectomy. Competing-risks models were used to compare cancer-specific survival. Cox proportional hazards models were used to assess overall survival. Subgroup analysis was performed comparing time periods 2004 to 2009 and 2010 to 2015. RESULTS: Of 2133 included individuals, 772 (36.2%) underwent ET and 1361 (63.8%) underwent esophagectomy. Unadjusted 5-year survival for cancer-specific death was 87.7% (95% confidence interval [CI], 84.2-90.5) for ET and 82.4% (95% CI, 80.0- 84.5) for esophagectomy (P = .002). Within the adjusted competing-risk model, cancer-specific survival was superior in patients treated with ET compared with esophagectomy (subdistribution hazard ratio [SHR], 1.92; 95% CI, 1.35-2.74; P < .001). From 2004 to 2009, the SHR for esophagectomy was 1.68 (95% CI, 1.07-2.66; P = .024); whereas from 2010 to 2015, the SHR for esophagectomy was 2.02 (95% CI, 1.08-3.76; P = .027). CONCLUSIONS: ET was associated with improved cancer-specific survival compared with esophagectomy in stage I esophageal cancer. This advantage was more pronounced for patients treated after 2009, potentially because of increasing clinician expertise in performing ET and patient selection.

The Association of State Firearm Legislation With the Burden of Firearm-Related Surgery.

BACKGROUND: United States state-level firearm legislation is linked to rates of firearm-related suicides, pediatric injuries, nonfatal injuries, hospital discharges, and mortality. Our objective was to evaluate the burden of firearm-related injuries requiring surgery for states with strict as opposed to nonstrict firearm legislation. MATERIALS AND METHODS: The 2014 Healthcare Cost and Utilization Project State Inpatient Database was utilized to extract data for all available 28 states and the District of Columbia. States were dichotomized into strict and nonstrict legislative categories using the 2014 Brady and Gifford's scores (15 strict, 14 nonstrict). Patients with a firearm injury requiring surgery were identified and the incidence of surgery aggregated to the county level. Negative binomial regression with an offset for county-level residential population was used to estimate the incident rate ratio for surgical volume comparing counties in strict and nonstrict states. Models were stratified by injury intent and adjusted for county population characteristics. RESULTS: A total of 11,939 patients were hospitalized with firearm-related injuries, with 65% (n = 7759) undergoing an operative procedure. The adjusted incidence rate of firearm-related surgery per 100,000 people was 1.29 (95% confidence interval; 1.13-1.46, P < 0.001) times higher and the adjusted cost of hospitalization per 100,000 people was $6028.69 ($3744.61-$8312.78, P = 0.001) greater for counties in nonstrict states than those for counties in strict states. The burden of health care for these injuries is invariably shifted to state- and county-level finances. CONCLUSIONS: The rate of firearm-related surgical intervention was higher for states with nonstrict firearm legislation than that for states with strict legislation. States should reevaluate their firearm legislation to potentially reduce the burden of firearm-related surgery and health care costs.

The Distribution of Colorectal Surgeons in the United States.

BACKGROUND: Surgical resection is a mainstay of colorectal cancer treatment, and prior studies have shown improved outcomes in patients undergoing surgery for colorectal cancer by colorectal surgical specialists compared with nonspecialized surgeons. Here, we examine the geographic distribution of colorectal surgeons in the United States and its relationship with sociodemographic characteristics of the served population. METHODS: The Area Health Resource File from 2017 to 2018 was used to identify the number and location of colorectal surgeons practicing throughout the United States and sociodemographic characteristics at the county and hospital referral region (HRR) level. The main outcomes of interest were the density of colorectal surgeons per 100,000 population and associations with sociodemographic characteristics at the county and HRR level based on multivariable linear regression. RESULTS: In multivariable analysis, regions with higher proportion of nonwhite individuals and college-educated individuals had significantly more colorectal surgeons per 100,000 population, whereas regions with higher proportions of uninsured individuals had significantly fewer colorectal surgeons per 100,000 population at both the county and HRR levels. CONCLUSIONS: Geographic and sociodemographic variability exists in the distribution of colorectal surgeons in the United States. Such variability may be contributing to disparities in access to specialized colorectal care.

Traumatic Brain Injury in Trauma Patients With Isolated Facial Fractures.

BACKGROUND: Diagnosis of traumatic brain injury (TBI), and specifically mild TBI (mTBI), is a diagnostic challenge which can delay diagnosis preventing early intervention and follow-up care. Facial fractures represent an objective surrogate marker for potential force transmission to the neural cavity. The authors' objective was to characterize the prevalence of TBI in trauma patients with isolated facial fractures stratified by injury severity. METHODS: The authors performed a retrospective cross-sectional study of the National Trauma Databank (NTDB) from 2007 to 2014 assessing a total of 1,867,761 participants identified as having a TBI and 306,785(60.2%) had an isolated facial fracture using ICD-9 codes. TBI severity was subdivided using Glasgow Coma Scale into mTBI and moderate-to-severe TBI. Logistic regression assessed odds of mTBI and moderate-to-severe TBI with different isolated facial fractures adjusted for injury severity. RESULTS: Trauma patients with isolated facial fractures of the nasal bone, mandible, malar region and maxilla, orbital floor, and alveolar and palate had a concomitant prevalence of mTBI ranging from 21.3% to 46.0% and moderate-to-severe TBI ranging from 7.3% to 18.4%. Mandibular fractures had the lowest odds of mTBI and moderate to severe TBI while alveolar and palate fractures had the highest odds of mTBI [OR3.20,95%CI (3.11-3.30)] and moderate to severe TBI [OR3.83,95%CI (3.65-4.01)]. CONCLUSIONS: Isolated facial fractures have a high prevalence of mTBI at all injury severity levels. Clinicians can use the presence of facial fractures in trauma patients to serve as clinical markers for TBI, without distracting from already existing trauma protocols and their focus on treatment of immediate life-threatening injuries raising both awareness and potential for early intervention.

Colon Neuroendocrine Tumors: A New Lymph Node Staging Classification.

BACKGROUND: The American Joint Commission on Cancer, the European Neuroendocrine Tumor Society, and the North American Neuroendocrine Tumor Society all classify colon neuroendocrine tumor (NET) nodal metastasis as N0 or N1. This binary classification does not allow for further prognostication by the total number of positive lymph nodes. This study aimed to evaluate whether the total number of positive lymph nodes affects the overall survival for patients with colon NET. METHODS: The National Cancer Database was used to identify patients with colon NET. Nearest-neighborhood grouping was performed to classify patients by survival to create a new nodal staging system. The Surveillance, Epidemiology, and End Results database was used to validate the new nodal staging classification. RESULTS: Colon NETs were identified in 2472 patients. Distinct 5-year survival rates were estimated for the patients with N0 (no positive lymph nodes; 69.8%; 95% confidence interval [CI], 66.7-72.7%), N1a (1 positive lymph node; 63.9%; 95% CI, 59.6-68.0%), N1b (2-9 positive lymph nodes; 38.9%; 95% CI, 35.4-42.3%), and N2 (≥ 10 positive lymph nodes; 15.7%; 95% CI, 11.9-20.0%; p < 0.001) nodal classifications. The validation population showed distinct 5-year survival rates with the new nodal staging. In multivariable Cox regression, the new nodal stage was a significant independent predictor of overall survival. CONCLUSIONS: The number of positive locoregional lymph nodes in colon NETs is an independent prognostic factor. For patients with colon NETs, N0, N1a, N1b, and N2 classifications for nodal metastasis more accurately predict survival than current staging systems.

New lymph node staging for rectal neuroendocrine tumors.

BACKGROUND AND OBJECTIVES: Current guidelines of the American Joint Commission on Cancer (AJCC) for rectal neuroendocrine tumors (NETs) classify tumor nodal status as N0/N1. This staging does not take into consideration the number of positive lymph nodes. The goal of this study is to determine how the number of positive lymph nodes affects the prognosis for patients with rectal NETs. METHODS: The National Cancer Database was used to identify patients with rectal NETs who underwent rectal resection. Nearest-neighborhood grouping was used to classify patients by survival to create a new nodal staging system. RESULTS: There were 687 patients with rectal NETs. There were distinct 5-year survival estimates for patients with N0 [81.8% (95%CI:77.1%-85.6%)], N1 (1-4 positive lymph nodes) [57.8% (95% confidence interval (CI: 51.2%-63.9%)] and N2 (≥5 positive lymph nodes) [32.6% (95%CI:25.1%-40.3%)] patients, P < 0.0001. Distinct 5-year survival estimates using the new nodal staging system was apparent for patients in the external validation set. After adjusting for predictors of survival in multivariable analysis, the new nodal stage remained an independent predictor of overall survival. CONCLUSIONS: The number of positive locoregional lymph nodes is an independent prognostic factor in rectal NETs. The next AJCC edition should consider classifying patients with rectal NETs as N0, N1, and N2 to provide better estimates of survival for patients.

Risk of appendiceal cancer in patients undergoing appendectomy for appendicitis in the era of increasing nonoperative management.

BACKGROUND AND OBJECTIVES: Management practices for acute appendicitis are changing. In cases of nonoperative treatment, the risk of missed or delayed diagnosis of malignancy should be considered. We aimed to identify predictors associated with appendiceal cancer diagnosis after appendectomy for acute appendicitis. MATERIALS AND METHODS: This retrospective cohort study was performed using the National Surgical Quality Improvement Program (NSQIP) appendectomy-targeted data set from 2016 to 2017. A total of 21 069 patients with imaging-confirmed or imaging indeterminate appendicitis who underwent appendectomy were included. Logistic regression was used to identify predictors of cancer diagnosis. RESULTS: Increasing age had an increasing monotonic relationship with the odds of pathologic cancer diagnosis after appendectomy (age 50-59 odds ratio [OR], 2.08, 95% confidence interval [CI], 1.28-3.39, P = .003; age 60-69 OR, 2.89, 95% CI, 1.72-4.83, P < .001; age 70-79 OR, 3.85, 95% CI, 2.08-7.12, P < .001; age >80 OR, 5.32, 95% CI, 2.38-11.9, P < .001). Other significant predictors included obesity, morbid obesity, normal preoperative white blood cell count, and imaging indeterminate for appendicitis. CONCLUSIONS: When counseling patients regarding operative vs nonoperative treatment options for management of acute appendicitis, the rising risk of a delayed or missed cancer diagnosis with increasing age must be discussed.

Association of Medicaid Expansion Policy with Outcomes in Homeless Patients Requiring Emergency General Surgery.

BACKGROUND: Medicaid expansion has reduced obstacles faced in receiving care. Emergency general surgery (EGS) is a clinical event where delays in appropriate care impact outcomes. Therefore, we assessed the association between non-Medicaid expansion policy and multiple outcomes in homeless patients requiring EGS. METHODS: We used 2014 State Inpatient Database to identify homeless individuals admitted with a primary EGS diagnosis who underwent an EGS procedure. States were divided into those that did and did not implement Medicaid expansion. Multivariable quantile regression was used to examine associations between non-Medicaid expansion states and (1) length of stay and (2) total index hospital charges within the homeless population. Multivariable logistic regression was used to assess the associations between non-Medicaid expansion and (1) mortality, (2) surgical complications, (3) discharge against medical advice, and (4) home healthcare. RESULTS: A total of 6930 homeless patients were identified. Of these, 435 (6.2%) were in non-expansion states. Non-Medicaid expansion was associated with higher charges (coef: $46,264, 95% CI 40,388-52,139). There were non-significant differences in mortality (OR 1.4, 95% CI 0.79-2.62; p = 0.2) or surgical complications (OR 1.16, 95% CI 0.7-1.8; p = 0.4). However, homeless individuals living in non-expansion states did have higher odds of being discharged against medical advice (OR 2.1, 95% CI 1.08-4.05; p = 0.02), and lower odds of receiving home healthcare (OR 0.6, 95% CI 0.4-0.8; p = 0.01). CONCLUSION: Homeless patients living in Medicaid expansion states had lower odds of being discharged against medical advice, higher likelihood of receiving home healthcare and overall lower total index hospital charges.

Face Transplant: Status of Current Supporting Technology to Plan and Perform the Operation and Monitor the Graft in the Postoperative Period.

Face transplant has rapidly advanced since the first operation in 2005, and to date, 40 partial or full-face transplants have been performed. The safety and efficacy of this operation are aided at all phases by supporting technologies. These include advanced imaging techniques to plan the operation, devices to monitor the flap in the immediate perioperative period, and noninvasive imaging and serum markers to monitor for acute and chronic rejection. Some of the technologies, such as those used in the immediate perioperative period, have extensive evidence supporting their use, whereas those to detect acute or chronic rejection remain investigational. The technologies of today will continue to evolve and make the operation safer with improved outcomes; however, the most significant barrier for face transplant continues to be immunologic rejection.

Cosmesis, patient satisfaction, and quality of life after da Vinci Single-Site cholecystectomy and multiport laparoscopic cholecystectomy: short-term results from a prospective, multicenter, randomized, controlled trial.

BACKGROUND: Single-incision laparoscopic cholecystectomy evolved from the traditional multiport laparoscopic technique. Prior trials have demonstrated improved cosmesis with the single-incision technique. Robotic single-site surgery minimizes the technical difficulties associated with laparoscopic single-incision approach. This is the first prospective, randomized, controlled study comparing robotic single-site cholecystectomy (RSSC) and multiport laparoscopic cholecystectomy (MPLC) in terms of cosmesis and patient satisfaction. METHODS: Patients with symptomatic benign gallbladder disease were randomized to RSSC or MPLC. Data included perioperative variables such as operative time, conversion and complications and cosmesis satisfaction, body image perception, quality of life using validated questionnaires, at postoperative visits of 2, 6 weeks and 3 months. RESULTS: One hundred thirty-six patients were randomized to RSSC (N = 83) and MPLC (N = 53) at 8 institutions. Both cohorts were dominated by higher enrollment of females (RSSC = 78%, MPLC = 92%). The RSSC and MPLC cohorts were otherwise statistically matched. Operative time was longer for RSSC (61 min vs. 44 min, P < 0.0001). There were no differences in complication rates. RSSC demonstrated a significant superiority in cosmesis satisfaction and body image perception (P value < 0.05 at every follow-up). There was no statistically significant difference in patient-reported quality of life. Multivariate analysis of female patients demonstrated significantly higher preference for RSSC over MPLC in cosmesis satisfaction and body image perception with no difference seen in overall quality of life. CONCLUSIONS: Results from this trial show that RSSC is associated with improved cosmesis satisfaction and body image perception without a difference in observed complication rate. The uncompromised safety and the improved cosmesis satisfaction and body image perception provided by RSSC for female patients support consideration of the robotic single-site approach.

Transition from Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair to Robotic Transabdominal Preperitoneal Inguinal Hernia Repair: A Retrospective Review of a Single Surgeon's Experience.

BACKGROUND: There is a paucity of literature comparing laparoscopic to robotic inguinal hernia repair. We present a single surgeon's transition from laparoscopic totally extraperitoneal (L-TEP) to robotic transabdominal preperitoneal (R-TAPP) inguinal hernia repair and compare outcomes from the two approaches. METHODS: This retrospective review and analysis of prospectively collected data compare outcomes during the transition from L-TEP to R-TAPP inguinal hernia repair by a single surgeon at one institution. Operating times and surgical outcomes and complications are analyzed. All consecutive L-TEP cases from November 2012 to August 2014 and all consecutive R-TAPP cases from March 2013 to October 2015 were included in the analysis. RESULTS: A total of 157 and 118 patients underwent L-TEP and R-TAPP inguinal hernia repair, respectively. The groups were similar regarding demographics and ASA class. A significantly higher number of complex cases were performed in the R-TAPP group compared to L-TEP group (n = 11 vs. n = 1, p = 0.0001). Mean surgical times were nearly identical (69.12 ± 35.13 min, R-TAPP; 69.05 ± 26.31, L-TEP) as were intraoperative and postoperative complication rates-despite the significantly higher number of complex cases in the R-TAPP group. CONCLUSIONS: This is the largest study in the literature comparing a single surgeon's experience transitioning from L-TEP to R-TAPP inguinal hernia repair. Results from the R-TAPP cases were similar to those achieved from laparoscopic cases. The robotic platform may have facilitated the execution of complex hernia cases during the proficiency phase.

A Relative Value Unit-Based Model for Targeted Nipple-Areola Complex Neurotization in Gender-Affirming Mastectomy.

Background: For transmasculine individuals, double-incision mastectomy with free nipple grafts is the most common procedure for gender-affirming chest masculinization. However, patients report decreased sensation postoperatively. Direct coaptation of intercostal nerves to the nipple-areolar complex (NAC) is an experimental technique that may preserve postoperative sensation, yet whether reimbursements and billing codes incentivize hospital systems and surgeons to offer this procedure lacks clarity. Methods: A retrospective cross-sectional analysis of fiscal year 2023 Medicare physician fee schedule values was performed for neurotization procedures employing Current Procedural Terminology codes specified by prior studies for neurotization of the NAC. Additionally, operative times for gender-affirming mastectomy at a single center were examined to compare efficiency between procedures with and without neurotization included. Results: A total of 29 encounters were included in the study, with 11 (37.9%) receiving neurotization. The mean operating time was 100.3 minutes (95% CI, 89.2-111.5) without neurotization and 154.2 minutes (95% CI, 139.9-168.4) with neurotization. In 2023, the average work relative value units (wRVUs) for neurotization procedures was 13.38. Efficiency for gender-affirming mastectomy was 0.23 wRVUs per minute without neurotization and 0.24 wRVUs per minute with neurotization, yielding a difference of 0.01 wRVUs per minute. Conclusions: Neurotization of the NAC during double-incision mastectomy with free nipple grafts is an experimental technique that may improve patient sensation after surgery. Current reimbursement policy appropriately values the additional operative time associated with neurotization relative to gender-affirming mastectomy alone.

Teardrop Alignment Changes After Volar Locking Plate Fixation of Distal Radius Fractures With Volar Ulnar Fragments.

BACKGROUND: We assessed factors associated with change in radiographic teardrop angle following volar locking plate (VLP) fixation of volarly displaced intra-articular distal radius fractures with volar ulnar fragments (VUF) within the ICUC database. The primary outcome was change in radiographic alignment on follow-up imaging, defined as a change in teardrop angle from intra-operative fluoroscopy greater than 5°. METHODS: Patients with distal radius fractures treated with a VLP within the ICUC database, an international collaborative and publicly available dataset, were identified. The primary outcome was volar rim loss of reduction on follow-up imaging, defined as a change in radiographic alignment from intra-operative fluoroscopy, teardrop angle less than 50°, or loss of normal radiocarpal alignment. Secondary outcomes were final range of motion (ROM) of the affected extremity. Radiographic Soong classification was used to grade plate position. Descriptive statistics were used to assess variables' distributions. A Random Forest supervised machine learning algorithm was used to classify variable importance for predicting the primary outcome. Traditional descriptive statistics were used to compare patient, fracture, and treatment characteristics with volar rim loss of reduction. Volar rim loss of reduction and final ROM in degrees and as compared with contralateral unaffected limb were also assessed. RESULTS: Fifty patients with volarly displaced, intra-articular distal radius fractures treated with a VLP were identified. Six patients were observed to have a volar rim loss of reduction, but none required reoperation. Volar ulnar fragment size, Soong grade 0, and postfixation axial plate position in relation to the sigmoid notch were significantly associated (P < .05) with volar rim loss of reduction. All cases of volar rim loss of reduction occurred when VUF was 10.8 mm or less. CONCLUSIONS: The size of the VUF was the most important variable for predicting volar rim loss of reduction followed by postfixation plate position in an axial position to the sigmoid notch and the number of volar fragments in the Random Forest machine learning algorithm. There were no significant differences in ROM between patients with volar ulnar escape and those without.
