RESUMO

BACKGROUND: The superficial inferior epigastric artery (SIEA) flap allows transfer of tissue without violating the rectus fascia. Traditionally it is best used in single stage reconstruction when vessel caliber is 1.5 mm; 56% to 70% of SIEAs are less than 1.5 mm and, therefore, not reliable. We aim to demonstrate the increased reliability of SIEA through surgical delay by quantifying reconstructive outcomes and delay-induced hemodynamic alterations. METHODS: Patients presenting for autologous breast reconstruction between May 2019 and October 2020 were evaluated with preoperative imaging and received either delayed SIEA or delayed deep inferior epigastric (DIEP) reconstruction based on clinical considerations, such as prior surgery and perforator size/location. Prospective data were collected on operative time, length of stay, and complications. Arterial diameter and peak flow were quantified with Doppler ultrasound predelay and postdelay. RESULTS: Seventeen delayed SIEA flaps were included. The mean age (± SD) was 46.2 ± 10.55 years, and body mass index was 26.7 ± 4.26 kg/m2. Average hospital stay after delay was 0.85 ± 0.90 days, and duration before reconstruction was 6 days to 14.5 months. Delay complications included 1 abdominal seroma (n = 1, 7.7%). Superficial inferior epigastric artery diameter predelay (mean ± 95% confidence interval) was 1.37 ± 0.20 mm and increased to 2.26 ± 0.24 mm postdelay. A significant increase in diameter was noted 0.9 ± 0.22 mm (P < 0.0001). Mean peak flow predelay was 14.43 ± 13.38 cm/s and 44.61 ± 60.35 cm/s (n = 4, P = 0.1822) postdelay. CONCLUSIONS: Surgical delay of the SIEA flap augments SIEA diameter, increasing the reliability of this flap for breast reconstruction. Superficial inferior epigastric artery delay results in low rates of complications and no failures in our series. Although more patients are needed to assess increase in arterial flow, use of surgical delay can expand the use of SIEA flap reconstruction and reduce abdominal morbidity associated with abdominal flap breast reconstruction.

RESUMO

Patients with a history of massive weight loss who are undergoing autologous breast reconstruction after mastectomy represent a unique surgical challenge. Although these patients often have an abundance of excess skin, it may be difficult to acquire sufficient tissue volume for adequate reconstruction of bilateral breasts using single flap techniques due to the paucity of subcutaneous fat. Stacked flap techniques have emerged as an effective method in thinner patients with suboptimal fat distribution who desire autologous breast reconstruction. This can serve as an ideal strategy, specifically in this patient population, when it serves the dual function of providing adequate volume for bilateral breast reconstruction and the secondary benefit of removing the excess skin present after massive weight loss. In this article, we discuss surgical techniques used during two cases of bilateral stacked flap breast reconstruction in cancer patients subsequent to massive weight loss.

RESUMO

BACKGROUND: Sarcopenia is linked to poor outcomes throughout the surgical literature and can be assessed on preoperative imaging to potentially aid in risk stratification. This study examined the effects of sarcopenia on surgical morbidity following lower extremity (LE) reconstruction, and also compared two methods of assessment, one of which is novel ("ellipse method"). METHODS: A retrospective cohort study of 50 patients receiving free flap-based reconstruction of the LE was performed. Bilateral psoas density and area were quantified at L4 through tracing ("traditional method") and encircling ("ellipse method") to calculate Hounsfield unit average calculation (HUAC). Logistic regression and receiving operator curve analysis for the primary outcome of any postoperative complication was used to determine HUAC cutoffs (≤ 20.7 vs. ≤ 20.6) for sarcopenia. Risk of complications associated with sarcopenia was evaluated using Fisher's exact tests. RESULTS: Twelve patients (24%) met criteria for sarcopenia via the traditional method and 16 (32%) via the ellipse method. By both methods, sarcopenic patients were older and more often female and diabetic. These patients also had higher American Society of Anesthesiologists scores and lower serum prealbumin levels. The ellipse method was found to be more accurate, sensitive, and specific than the traditional method in predicting postoperative morbidity (p = 0.009). Via the ellipse method, sarcopenic patients were at higher risk for any complication (p = 0.002) and were at a higher risk for a deep vein thrombus or pulmonary embolism via the traditional method (p = 0.047). CONCLUSION: Sarcopenia is associated with greater pre- and postoperative morbidity in LE reconstruction. The novel ellipse method is a simplified and accurate method of assessing sarcopenia that can be easily performed in the clinical setting.

RESUMO

BACKGROUND: In 2011, the ACGME limited duty hours for residents. Although studies evaluating the 2011 policy have not shown improvements in general measures of morbidity or mortality, these outcomes might not reflect changes in specialty-specific practice patterns and secondary quality measures. STUDY DESIGN: All trauma admissions from July 2009 through June 2013 at an academic Level I trauma center were evaluated for 5 primary outcomes (eg, mortality and length of stay), and 10 secondary quality measures and practice patterns (eg, operating room [OR] visits). All variables were compared before and after the reform (July 1, 2011). Piecewise regression was used to study temporal trends in quality. RESULTS: There were 11,740 admissions studied. The reform was not strongly associated with changes in any primary outcomes except length of stay (7.98 to 7.36 days; p = 0.01). However, many secondary quality metrics changed. The total number of OR and bedside procedures per admission (6.72 to 7.34; p < 0.001) and OR visits per admission (0.76 to 0.91; p < 0.001) were higher in the post-reform group, representing an additional 9,559 procedures and 1,584 OR visits. Use of minor bedside procedures, such as laboratory and imaging studies, increased most significantly. CONCLUSIONS: Although most major outcomes were unaffected, quality of care might have changed after the reform. Indeed, a consistent change in resource use patterns was manifested by substantial post-reform increases in measures such as bedside procedures and OR visits. No secondary quality measures exhibited improvements strongly associated with the reform. Several factors, including attending oversight, might have insulated major outcomes from change. Our findings show that some less-commonly studied quality metrics related to costs of care changed after the 2011 reform at our institution.
