Quality of Life After Lower Leg Reconstruction With the Latissimus Dorsi Free Flap in Pediatric Patients.

BACKGROUND: The latissimus dorsi free flap is a widely used reconstructive technique for complex lower leg defects in the pediatric population due to its reliability and anatomical features. However, the impact of this technique on the postoperative quality of life in children and adolescents, who require appropriate lower extremity function during their developmental period, remains to be analyzed. METHODS: Patients who underwent microsurgical lower leg reconstruction using the latissimus dorsi flap were analyzed retrospectively. The quality of life of these patients was assessed prospectively using the Lower Extremity Functional Scale (LEFS) at a minimum of 18 months after surgical reconstruction. RESULTS: Sixteen pediatric patients who had severe lower extremity injuries and underwent latissimus dorsi free flap reconstruction met the inclusion criteria. The mean follow-up period was 33.9 months (22-64 months). Two patients experienced postoperative complications: one had partial flap necrosis and surgical site infection, while the other developed a surgical site infection. The LEFS scores ranged from 26 to 80, with a mean score of 64.6. Remarkably, 14 of 16 patients achieved LEFS scores consistent with at least the 10th percentile when compared with normative data. Patients with severe associated fractures presented with the lowest scores. CONCLUSIONS: Based on our findings, the latissimus dorsi flap is reaffirmed to be an excellent choice for lower leg reconstruction in the pediatric population. It effectively restores the quality of life in patients who have experienced moderate to severe lower extremity injuries.

The Implications of Laterality in Unilateral Cleft Lip Reconstruction: A Global Survey of Cleft Surgeons.

OBJECTIVE: To explore the impact of directional laterality in complete Unilateral Cleft Lip (UCL) amongst the global cleft surgeon community. DESIGN: Cross-sectional survey study. SETTING: Global distribution of online survey distributed in English and Spanish. PARTICIPANTS: Cleft surgeons from around the world. MAIN OUTCOME MEASURES: Survey participant perception of the impact of laterality on: (1) cleft presentation (2) surgical challenge and (3) surgical outcomes. RESULTS: Responses were received from 453 cleft surgeons located in 54 countries around the world. 221 (49%) had previously considered differences in patients presenting with a left- versus right-sided UCL. 95 (21%) considered right-sided clefts more difficult to reconstruct, 37 (8%) reported left-sided clefts to be more difficult and 321 (71%) reported no difference in difficulty between the cleft sides. Higher volume cleft surgeons, characterised by those reporting cleft as their principal area of practice and performing >20 cleft operations per year, were more likely to have both previously considered differences in laterality in cleft and to report right-sided unilateral cleft lip to be more difficult to primarily reconstruct. 395 (87%) did not consider surgical outcomes to be influenced by cleft laterality. CONCLUSIONS: This survey reports perceptions on cleft laterality from a large body of global surgeons and suggests a trend for increased difficulty in right-sided compared to left-sided cleft lip reconstruction, where such laterality-associated difficulty is perceived.

The profunda artery perforator free flap for lower extremity reconstruction.

BACKGROUND: The profunda artery perforator (PAP) flap has been reported in several types of reconstructions. This report aims to evaluate the usefulness and the clinical outcome of patients who underwent the PAP free flap for lower limb reconstruction. METHODS: Between February 2018 and February 2020, nine patients with injury at lower third of the leg, foot dorsum or foot plant (eight acute injuries and one chronic ulcer) were selected. Mean wound size was 12.5 × 6.3 cm (9 × 5-14.5 × 6.5). Inclusion criteria consisted in patient's request to hide the donor site scar and the absence of previous traumas or surgery in the donor site. Patients considered unable to bear prolonged surgery were excluded. Patients underwent preoperative CT angiography and peri-operative Doopler, for perforator selection. All flaps were designed with pinch test, in elliptical shape. Microvascular anastomosis was performed to the tibialis anterior/posterior or medial plantar vessels. Outcomes were evaluated in terms of wound coverage success and patient's quality of life through Lower Extremity Functional Scale (LEFS) questionnaire. RESULTS: The mean size of the harvested skin paddle was 13.5 × 7.4 cm (9 × 6-15 × 8) and mean pedicle length was 8.5 cm. Mean flap harvest time was 43.5 min (35-55). Flap survival rate was 100%, with one re-exploration with minimal partial flap loss. Mean follow-up was 13.5 months . Reconstructive results were successful in wound coverage and function. All patients reported satisfaction with their result by LEFS questionnaire (score:64.7). CONCLUSION: With proper patient selection, there was 100% flap survival rate with no major complication. According to our data, the PAP free flap could be a valuable option for lower extremity reconstruction.

Experiencia y manejo de dos pacientes pediátricos grandes quemados e infección por SARS-CoV-2 en una unidad de cuidados intensivos / Experience and management of two paediatric patients infected with SARS-CoV-2 with major burn injuries in an intensive care unit

RESUMEN La infección por SARS-CoV-2 se ha diseminado rápidamente, provocando una pandemia mundial en la cual nos vemos afectados. En el Instituto Nacional de Salud del Niño de San Borja, centro de referencia nacional de pacientes pediátricos quirúrgicos, desde el 14 de abril al 12 de agosto del 2020, se hospitalizaron 106 pacientes con infección por SARS-CoV-2, de los cuales 11 tuvieron diagnostico quemadura y dos fueron pacientes grandes quemados con diagnóstico COVID-19 por prueba molecular. Detallamos el caso de una paciente pediátrica, de siete años, gran quemada que fue atendida en unidad de cuidados intensivos, y con COVID-19 asintomática, presentó evolución y pronóstico favorable, con recuperación total de su lesión. Por otro lado, el COVID-19 se puede manifestar de forma severa produciendo un síndrome inflamatorio multisistémico que presenta manifestaciones clínicas poco comunes y que puede empeorar el pronóstico, como fue observado en nuestro otro paciente de siete meses que falleció pese a recibir manejo especializado y oportuno.

ABSTRACT SARS-CoV-2 infection is rapidly disseminating, leading to a world pandemics in which we are also affected. In San Borja Peruvian National Children Health Institute, which is the reference center for surgical pediatric patients, 106 patients infected with SARS-CoV-2 were hospitalized. Of them, 11 presented with burns and two had large burns. The viral infection was diagnosed using molecular testing. We present in detail the case of a pediatric seven-year old patient who had large burns and was taken care of in the intensive care unit. She had asymptomatic SARS-CoV-2 infection, and her outcome was good, with a good prognosis, and she recovered completely and uneventfully. On the other hand, COVID-19 may present as a severe disease leading to a multi- systemic inflammatory syndrome with some uncommon clinical manifestations which affect its prognosis , as it was the case with another seven-month old patient who passed away in spite of having received specialized and timely therapy.

Impact of body mass index on long-term surgical outcomes of vascularized lymph node transfer in lymphedema patients.

BACKGROUND: Vascularized lymph node transfer (VLNT) is a surgical procedure with high interest to treat lymphedema. Body mass index (BMI) is a well-described factor that increases the risk of lymphedema, but little is known about its influence on the surgical outcomes of lymphedema patients who undergo VLNT. The aim of this study was to analyze the impact of preoperative BMI on the long-term surgical outcomes after VLNT in lymphedema patients. METHODS: We retrospectively compiled data of patients with International Society of Lymphology (ISL) stage II or III lymphedema who were treated with VLNT from July 2010 to July 2016 at China Medical University Hospital. Preoperative and postoperative demographic and clinical data, such as limb circumference and number of infection episodes were reviewed. Statistical analyses compared circumference reduction rates and infection episode reduction between preoperative BMI categories was done. In addition, prediction of outcomes based on quantitative preoperative BMI was analyzed. RESULTS: A total of 83 patients met the inclusion criteria. Nine patients (10.8%) were normal weight, 43 (51.8%) were overweight, and 31 (37.3%) were obese. Compared with normal-weight patients, mean circumference reduction rates were significantly lower in overweight (P=0.005) and obese patients (P=0.02), but quantitative BMI was not correlated with circumference reduction rate (P=0.96). However, obese patients had a significantly greater reduction in infection episodes than normal-weight patients (P=0.03). In addition, greater BMI predicted greater reduction in infection episodes after VLNT (P=0.02). CONCLUSIONS: VLNT is an effective surgical treatment, especially for lymphedema patients with higher preoperative BMIs. The results of our study suggest that this procedure considerably decreases the number of postoperative infection episodes per year in obese patients, even though preoperative BMI does not influence circumference reduction rate.

The Modified Extended Fleur-De-Lis Latissimus Dorsi Flap for Various Complex Multi-directional Large Soft and Bone Tissue Reconstruction.

Introduction Latissimus Dorsi (LD) myocutaneous flap is a workhorse flap for various large reconstructions. Variants described to increase its volume are referred to as extended LD flaps. The extended fleur-de-lis LD is one of these variants. We report the clinical outcomes using a modified extended fleur-de-lis LD flap for complex multi-directional soft and bone tissue defects. Methods Between 2010 and 2017, 29 patients underwent the modified extended fleur-de-lis LD flaps, whose sizes were between 120 cm2 and 442 cm2. The mean age was 47.55 ± 9.07 years. Locations of the defects included head and neck (nine cases), upper extremity (six cases), lower extremity (nine cases) and chest wall regions (five cases). Results Of the 29 extended fleur-de-lis LD flaps, 11 were pedicled and 18 were free flaps. A total of 10 flaps were osteomyocutaneous and 19 were myocutaneous. The mean vertical size of the harvested skin paddle was 30.72 ± 4.57 cm (range: 20-38), and the mean horizontal size of the skin paddle was 8.69 ± 0.80 (range: 7-10) cm, with the mean maximum horizontal extensions of the flaps being 16.03 ± 1.18 (range: 14-18) cm. The flap survival rates were 100%. One flap had distal partial loss (less than 5%). Donor site complications included seroma (1) and numbness (1), both of which were managed conservatively. The average follow-up time was 23.97 ± 7.19 months. Conclusion The presented modified extended fleur-de-lis LD myocutaneous/osteomyocutaneous flap for reconstruction of multi-directional complex soft tissue and bone defects is a good and reliable option, with low donor site morbidity.
