The Effect of Body Mass Index on Free Flap Breast Reconstruction

BACKGROUND

 Literature addressing the risks associated with increasing body mass index (BMI) for patients undergoing free flap breast reconstruction is limited. Often, an arbitrary BMI cutoff (i.e., BMI of 30 kg/m2) is used to determine candidacy for a free flap without substantial backing evidence. This study utilized a national multi-institutional database to analyze outcomes of free flap breast reconstruction and stratified complications by BMI class.

METHODS

 Using the 2010 to 2020 National Surgical Quality Improvement Program database, patients who underwent free flap breast reconstruction were identified. Patients were divided into six cohorts based on the World Health Organization BMI classes. Cohorts were compared by basic demographics and complications. A multivariate regression model was created to control for age, diabetes, bilateral reconstruction, American Society of Anesthesiologists class, and operative time.

RESULTS

 Surgical complications increased with each BMI class, with the highest rates occurring in class I, II, and III obesity, respectively. In a multivariable regression model, the risk for any complication was significant for class II and III obesity (odds ratio [OR]: 1.23, p < 0.004; OR: 1.45, p < 0.001, respectively). Diabetes, bilateral reconstruction, and operative time were independently associated with an increased risk of any complication (OR: 1.44, 1.14, 1.14, respectively, p < 0.001).

CONCLUSION

 This study suggests that the risks of postoperative complications following free flap breast reconstruction are highest for patients with a BMI greater than or equal to 35 kg/m2, having nearly 1.5 times higher likelihood of postoperative complications. Stratifying these risks by weight class can help guide preoperative counseling with patients and help physicians determine candidacy for free flap breast reconstruction.

Surgical Management of Pachyonychia Congenita in a 3-Year-Old

Pachyonychia congenita is a rare genetic disorder characterized by hypertrophic nail plates, hyperkeratotic nail beds, and thickened hyponychium of the fingers and toes, impairing manual dexterity and resulting in poor aesthetics. The current body of literature describes various treatment modalities, but no singular approach has been defined as the gold standard. In this case, the authors employed different surgical techniques for treating pachyonychia congenita to evaluate the most effective approach. A 3-year-old boy presented with hypertrophic nail growth involving all digits of both hands and feet. Three surgical procedures were performed on the patient's fingers and toes using germinal matrix excision (GME) alone, GME plus partial sterile matrix excision (pSME), or GME plus complete sterile matrix excision (cSME). The digits treated with GME + cSME exhibited no recurrence of nail growth. Those treated with GME alone exhibited recurrence of hypertrophic nail growth, although their growth slowed. Excision of GME + cSME prevented recurrence of hypertrophic nails, while GME alone or with pSME led to slower-growing hypertrophic nails. Complete excision of the germinal and sterile matrices with skin graft closure may be a definitive treatment for pachyonychia congenita, but further studies are needed to validate these findings.

Scheduled Postoperative Ketorolac Does Not Decrease Opiate Use following Free Flap Breast Reconstruction

BACKGROUND

 In the setting of the opioid crisis, managing postoperative pain without the exclusive use of opiates has become a topic of interest. Many hospitals have begun implementing enhanced recovery after surgery protocols to decrease postoperative complications, hospital costs, and opiate utilization. Ketorolac has been added to many of these protocols, but few studies have examined its effects independently.

METHODS

 A retrospective chart review was performed on all patients that received autologous breast reconstruction from October 2020 to June 2022 at an academic institution. We identified patients who did and did not receive postoperative ketorolac. Use of ketorolac was based upon surgeon preference. The two groups were compared in basic demographics, reconstruction characteristics, length of stay, complications, reoperations, and morphine milligram equivalents (MMEs).

RESULTS

 One-hundred ten patients were included for the analysis, with 55 receiving scheduled postoperative ketorolac and 55 who did not receive ketorolac. There were seven incidences of postoperative complications in each group (12.7%, p = 1.00). The total mean postoperative MMEs were 344.7 for the nonketorolac group and 336.5 for the ketorolac group (p = 0.81). No variable was found to be independently associated with postoperative opiate use. Ketorolac was not found to contribute significantly to any postoperative complication.

CONCLUSION

 In this study, the use of ketorolac did not significantly reduce opiate use in a cohort of 110 patients. Surgeons should consider whether the use of ketorolac alone is the best option to reduce postoperative opiate use following free flap breast reconstruction.

A Comparison of Postoperative Outcomes Between Immediate, Delayed Immediate, and Delayed Autologous Free Flap Breast Reconstruction: Analysis of 2010-2020 NSQIP Data

BACKGROUND

 While many factors influence decisions related to the timing between mastectomy and flap-based breast reconstruction, there is limited literature comparing postoperative complications between immediate (IBR), delayed immediate (DIBR), and delayed (DBR) reconstruction modalities. Using the National Surgical Quality Improvement Program (NSQIP), we sought to compare postoperative complication rates of each timing modality.

METHODS

 The NSQIP 2010-2020 database was queried for patients who underwent free flap breast reconstruction. Cases were categorized to include mastectomy performed concurrently with a free flap reconstruction, removal of a tissue expander with free flap reconstruction, and free flap reconstruction alone which are defined as IBR, DIBR, and DBR, respectively. The frequency of postoperative outcomes including surgical site infection (SSI), wound dehiscence, intraoperative transfusion, deep venous thrombosis (DVT), and return to operating room (OR) was assessed. Overall complication rates, hospital length of stay (LOS), and operative time were analyzed. Multivariable regression analysis controlling for age, race, BMI, diabetes, hypertension, ASA class, and laterality was performed.

RESULTS

 A total of 7,907 cases that underwent IBR, DIBR (n = 976), and DBR reconstruction (n = 6,713) were identified. No statistical difference in occurrence of SSIs, wound dehiscence, or DVT was identified. DIBR (9%) and DBR (11.9%) were associated with less occurrences of reoperation than IBR (13.2%, p < 0.001). Univariate and multivariate regression analysis demonstrated that DIBR and DBR were associated with a lower odds of complications and shorter operation time versus IBR. No statistically significant differences between DIBR and DBR in surgical complications, LOS, and operative time were identified.

CONCLUSION

 Awareness of overall complication rates associated with each reconstructive timing modality can be used to help guide physicians when discussing reconstructive options. Our data suggests that DIBR and DBR are associated with less overall complications than IBR. Physicians should continue to consider patients' unique circumstances when deciding upon which timing modality is appropriate.

Pronator Quadratus Muscle Flap for Prevention of Flexor Tendon Rupture after Distal Radius Volar Plating

Background

Flexor tendon rupture is a serious but rare complication that can occur after volar plating of distal radius fractures. This study aims to introduce a novel surgical technique that uses a pronator quadratus (PQ) muscle flap transposition to protect the flexor tendons from rupture or irritation and evaluate its outcomes.

Methods

A retrospective review was conducted on 204 patients with unstable distal radius fractures who underwent a standard volar flexor carpi radialis approach with extended release of the PQ muscle during exposure. A PQ muscle flap was harvested and transposed over the distal edge of the plate after open reduction and internal fixation of the distal radius. Postoperatively, patients were evaluated for flexor tendon irritation and rupture. Patients who had this injury before the use of the PQ flap were compared with the patients who received the PQ flap.

Results

Of the 204 patients, 119 received the PQ flap, and 85 did not. The mean follow-up time was 30.4 months. Among the patients who did not receive the PQ flap, five (5.9%) required plate removal or conservative treatment for tendon irritation or rupture. In contrast, only one patient (0.8%) who received the PQ flap required plate removal for flexor tendon irritation.

Conclusions

The PQ muscle flap is a quick and effective surgical technique that reduces the risk of flexor tendon rupture or irritation during distal radius fracture fixation. The PQ muscle flap acts as a buffer between the plate and tendon and is more effective than not transposing the muscle.

A Comparison of Postoperative Outcomes between Unilateral and Bilateral Palatoplasty: Analysis of 2015-2020 Pediatric NSQIP Data

OBJECTIVE

We sought to identify differences in 30-day medical and surgical complications in unilateral versus bilateral palatoplasty.

DESIGN

The NSQIP-P 2015-2020 database was queried to identify cleft palate repairs using CPT codes. Cases were stratified as unilateral (Veau III) and bilateral (Veau IV) using ICD-9 and -10 codes.

SETTING

A nationally representative random sample.

PATIENTS/PARTICIPANTS

A total of 3791 cases were identified with 2608 undergoing unilateral repair and 1183 undergoing bilateral repair.

MAIN OUTCOMES/MEASURES

The postoperative outcomes of interest included surgical complications (surgical site infections, wound dehiscence), medical complications (pneumonia, urinary tract infection, seizure, cardiac arrest, bleeding/transfusions, systemic sepsis, unplanned intubation), readmission, and reoperation.

RESULTS

The bilateral cohort was older (696 days versus 619 days, P < .001) and had longer operative times (157.3 min versus 144.5 min, P < .001). The unilateral cohort had more comorbidities including developmental delay, structural CNS abnormalities, need for nutritional support, and bleeding disorders. The bilateral cohort had statistically significant higher occurrences of wound dehiscence (2.1% versus. 1.2%, P = .03) and readmission (3.2% versus 1.7%, P = .01). On multivariate analysis, bilateral cleft repair (OR: 1.83, CI: 1.176-2.840, P = .007) and ASA class 4 (OR: 13.1, CI 2.288- 62.586, P = .002) were associated with greater odds of readmission.

CONCLUSION

Patients who underwent bilateral cleft repair had a higher proportion of 30-day postoperative complications and a two-fold increased odds of readmission. While palatoplasty is generally regarded as a safe procedure in the pediatric population, identifying factors related to an increased risk of early postoperative complications can help surgical teams better manage high-risk individuals.

An Evaluation of Early Complications after Prepectoral Tissue Expander Placement in First-Stage Breast Reconstruction with and without Acellular Dermal Matrix

PURPOSE

Prepectoral breast reconstruction has become popularized with the concurrent use of acellular dermal matrix (ADM). We sought to compare three-month postoperative complication rates and explantation rates for first stage, tissue expander based prepectoral breast reconstruction with and without the use of ADM.

METHODS

A single institution retrospective chart review was performed to identify consecutive patients undergoing prepectoral tissue-expander based breast reconstruction from August 2020 to January 2022. Chi-squared tests were used to compare demographic categorical variables and multiple variable regression models were used to identify variables associated with three-month postoperative outcomes.

RESULTS

We enrolled 124 consecutive patients. Fifty-five patients (98 breasts) were included in the no-ADM cohort and 69 patients (98 breasts) were included in the ADM cohort. There were no statistically significant differences between ADM and no-ADM cohort in regard to 90-day postoperative outcomes. On multivariable analysis, there were no independent associations between seroma, hematoma, wound dehiscence, mastectomy skin flap necrosis, infection, unplanned return to the OR, or explanation in the ADM or no ADM groups after controlling for age, BMI, history of diabetes, tobacco use, neoadjuvant chemotherapy, and postoperative radiotherapy.

CONCLUSION

Our results reveal no significant differences in odds of postoperative complications, unplanned return to the OR, or explantation between ADM and no-ADM cohorts. More studies are needed to evaluate the safety of prepectoral, tissue expander placement without ADM.

Novel Custom Maxillary Disimpaction Splint

LeFort I, II, and III osteotomies are commonly used in complex craniofacial reconstruction. Patients requiring these procedures typically have a craniofacial cleft, other congenital craniofacial deformities, or severe facial trauma. Both the cleft and traumatized palate have poor bony support, which leads to possible complications when the disimpaction forceps are used during the downfracture of the maxilla. Such potential complications include trauma or formation of a fistula of the palatal, oral, or nasal mucosa; trauma to adjacent teeth; and fracture of the palate and alveolar bone. To help prevent these complications, we developed a custom disimpaction splint. The splint is designed to cover the palate and occlusal surfaces to increase retention and minimize splint movement during the maxillary downfracture portion of the surgical procedure. The base of the splint is fabricated from a two-layered biocryl material, and the palatal area is built with soft-cushion rebase material. This allows for a stable grip of the disimpaction forceps blades and provides protective coverage of the cleft, traumatized palate, or alveolar bone graft site during the downfracture. The custom maxillary disimpaction splint has been routinely used in our clinic from September 2019 to the present for LeFort osteotomies in patients with a compromised primary palate. No surgical complications related to the maxillary downfracture have been noted during this period of time. We conclude that the routine use of a custom maxillary disimpaction splint can result in improved outcomes and decreased complications of LeFort osteotomy procedures in patients with cleft and traumatized palate.

Serum procalcitonin level is independently associated with mechanical ventilation and case-fatality in hospitalized COVID-19-positive US veterans-A potential marker for disease severity

The Coronavirus-19 disease (COVID-19) has claimed over 6.8 million lives since first being reported in late 2019. The virus that causes COVID-19 disease is highly contagious and spreads rapidly. To date, there are no approved prognostic tools that could predict why some patients develop severe or fatal disease outcomes. Early COVID-19 studies found an association between procalcitonin (PCT) and hospitalization or duration of mechanical ventilation and death but were limited by the cohort sizes. Therefore, this study was designed to confirm the associations of PCT with COVID-19 disease severity outcomes in a large cohort. For this retrospective data analysis study, 27,154 COVID-19-positive US veterans with post-infection PCT laboratory test data and their disease severity outcomes were accessed using the VA electronic healthcare data. Cox regression models were used to test the association between serum PCT levels and disease outcomes while controlling for demographics and relevant confounding variables. The models demonstrated increasing disease severity (ventilation and death) with increasing PCT levels. For PCT serum levels above 0.20 ng/ml, the unadjusted risk increased nearly 2.3-fold for mechanical ventilation (hazard ratio, HR, 2.26, 95%CI: 2.11-2.42) and in-hospital death (HR, 2.28, 95%CI: 2.16-2.41). Even when adjusted for demographics, diabetes, pneumonia, antibiotic use, white blood cell count, and serum C-reactive protein levels, the risks remained relatively high for mechanical ventilation (HR, 1.80, 95%CI: 1.67-1.94) and death (HR, 1.76, 95%CI: 1.66-1.87). These data suggest that higher PCT levels have independent associations with ventilation and in-hospital death in veterans with COVID-19 disease, validating previous findings. The data suggested that serum PCT level may be a promising prognostic tool for COVID-19 severity assessment and should be further evaluated in a prospective clinical trial.

A Custom Stabilizing Splint for the Management of BLCP with Protruding Premaxilla

A severely protruding premaxilla in a patient with bilateral cleft lip and palate prevents functional closure of the orbicularis oris muscle and acceptable reconstruction of the nasolabial components during primary cheiloplasty. This is typically corrected with vomerine osteotomy and premaxillary setback, followed by cheiloplasty and rhinoplasty. Due to the risk of vascular compromise to the prolabium and premaxillary segment, the lip and nose repair is often staged after the vomerine osteotomy and premaxillary setback has healed. Stabilizing the premaxillary segment to allow adequate healing has been a topic of interest. Several methods have been described, but each is associated with varying degrees of compromise of the blood supply to the premaxilla. To combat this, the authors created a custom oral splint that effectively maintained the position of the premaxilla with minimal impingement of the blood supply. The authors present two cases in which a two-stage premaxillary setback with a custom-stabilizing oral splint was performed, followed by primary cheiloplasty and rhinoplasty in an age-appropriate and delayed presentation of bilateral cleft lip and palate and protruding premaxilla.
