Lipoabdominoplasty: What We Have Implemented and What We Have Modified over 26 Years.

Lipoabdominoplasty is one of the most commonly performed procedures in body-contouring surgery. We present a retrospective study of our 26 years of experience to improve the results and assure the greatest possible safety in lipoabdominoplasty. We include all of our female patients who underwent lipoabdominoplasty performed from July 1996 to June 2022, dividing the patients into two groups: group I underwent circumferential liposuction avoiding abdominal flap liposuction for the first 7 years, and group II underwent circumferential liposuction including abdominal flap liposuction for the subsequent 19 years, pointing out the differences in the processes, results, and complications of both groups. Over a period of 26 years, 973 female patients underwent lipoabdominoplasty: 310 in group I and 663 in group II. Ages were very similar; however, weight, BMI, amount of liposuction material, and weight of the abdominal flap removed were higher in group I. Twenty percent of patients in group I were obese compared to 7% in group II. The average amount of liposuction in group I was 4990 mL compared to 3373 mL in group II and 1120 g of abdominal flap in group I versus 676 g in group II. Minor and major complications were 11.6% and 1.2% in group I versus 9.2% and 0.6% in group II, respectively. In our more than 26 years of performing lipoabdominoplasty, we have maintained most of our initial procedures. These processes have allowed us to perform surgery safely and effectively with a low morbidity rate.

Disease presentation and surgical treatment of patients with foreign-body granulomas and ASIA syndrome: case series.

BACKGROUND: The result of illicit polymer injection is chronic inflammation with foreign-body granuloma (FBG) formation. Treatment can be divided into medical and surgical. Some patients develop severe complications with need surgical treatment. This study aims to describe patients who underwent surgical removal of the FBGs and autoimmune/inflammatory syndrome induced by adjuvants (ASIA); additionally, we evaluated the quality of life after surgery. METHODS: In this retrospective single-center study, the authors examined data of patients who underwent surgical removal of FBG caused by illicit polymer injection for cosmetic purposes and confirmed ASIA from 2015 to 2020 by three different surgical approaches. Descriptive summary statistics were reported on patient demographics, presenting symptoms and clinical examination features, treatment strategies, histopathology reports and quality of life. RESULTS: The cohort included 11 female patients with FBGs and ASIA. The most affected anatomical zones were the combination of gluteal region, thighs and legs (40%); and thighs with legs (20%). Main presentation was: skin hyperpigmentation (90.9%), skin induration (63.6%), chronic fatigue (63.6%), and ulcers (36.4%). Surgical modalities consisted of: ultrasonic-assisted liposuction in four patients (36.4%); open en bloc excision and primary closure in four patients (36.4%); and open en bloc excision and microsurgical reconstruction in three patients (27.2%). The postoperative quality of life visual analog scale score was 83.9. CONCLUSIONS: ASIA treatment represents a challenge for the plastic surgeon. Adequate surgical treatment emphasizing, when possible, the total or near-total resection of the FBG must be performed to improve ASIA evolution.

Master Series Microsurgery for Residents: Results from a Comprehensive Survey of a Multitudinous Online Course during COVID-19 Pandemic.

BACKGROUND: Since COVID-19 emerged, it has significantly affected medical education. Surgical training has been blocked and the learning curve flattened. However, COVID-19 led to the outbreak of multitudinous online courses. Master series: microsurgery for residents (MSMR) has been the most extensive and accessible online nonfee course transmitted so far regarding reconstructive microsurgery. The primary aim of this study was to assess the impact of the MSMR in the surgical community as an international educational tool during pandemic confinement. METHODS: A retrospective, observational, analytic, and transversal study was designed. An 11-item survey was sent to all the 1,513 attendees who completed at least 60% of course attendance during 2 days. Descriptive and analytic statistics were performed. The impact was measured by considering answers to questions 6 to 9 and 11 (course usefulness, microsurgery interest increase, desire to pursue a microsurgical career, attendance to in-person conferences, and overall score, respectively). RESULTS: A total of 1,111 (73.4%) of eligible subjects were included. In total, 55.8% were plastic surgery residents. After the course, 98.9% would pursue a career in reconstructive microsurgery, and 45% would stop attending in-person conferences. The overall score of the event was 9.06 ± 0.9 (from 0 to 10) regardless of the current training status. CONCLUSION: The MSMR was a high impact course and has established a paradigm shift that will lead to an evolution in plastic surgery learning.

Variante de colgajo de rotación tipo Hamstring para reconstrucción de úlcera isquiática / Hamstring rotation fl ap variant for ischial ulcer reconstruction

Antecedentes. El colgajo Hamstring es una opción válida para la reconstrucción de úlceras isquiáticas. Las úlceras por presión representan un verdadero desafío para el cirujano plástico. Requieren un tratamiento especializado y multidisciplinario por su alta probabilidad de recidiva y las complicaciones en su manejo. Por lo general, ocurren por presión sostenida sobre la tuberosidad isquiática. Caso clínico. Se presenta el caso de un paciente parapléjico desde el nacimiento secundario a mielomeningocele con diagnóstico actual de úlcera isquiática. Se le realizaron durante 3 años múltiples intentos de cierre quirúrgico alternando medidas conservadoras, sin éxito. A la exploración física presenta una úlcera isquiática izquierda de 6x6 cm a la que se le realizó aseo y desbridación quirúrgica más cierre por medio de un colgajo Hamstring modificado. A los 7 días presentó dehiscencia de herida la cual se manejó de manera conservadora y cierre primario diferido a las 4 semanas. A 8 meses de posoperatorio el paciente se encuentra con buena evolución y con resultado estético y funcional aceptable, por otra parte, se encuentra sin recidiva, lo que ha permitido su reinserción laboral y un buen equilibrio físico-psico-emocional. Conclusión. El objetivo de este colgajo es brindar cobertura al área isquiática sin afectar estructuras adyacentes, lo cual requiere de un amplio conocimiento de la anatomía de la región femoral, así como de los colgados tanto locales como regionales que podemos utilizar para la reconstrucción. Actualmente este colgajo es una opción terapéutica efectiva para el tratamiento de úlceras isquiáticas refractarias en centros que cuentan con cirujanos plásticos no especializados en microcirugía.

Background. The Hamstring fl ap is an adequate option for ischial ulcers reconstruction. Pressure ulcers represent a real challenge for the plastic surgeon. They require specialized and multidisciplinary treatment due to their high recurrence probability and complications in their management. Regularly, pressure ulcers occur when sustained pressure is applied on the ischial tuberosity. Case report. We report a case of a 23-year-old paraplegic male with myelomeningocele complaining for an ischial ulcer. Multiple attempts to surgical closure were made during three years along with conservative management, without success. Physical examination revealed a 6x6 cm left ischial ulcer, which was managed with surgical debridement and closure with a modifi ed Hamstring fl ap. After 7 days, the patient presented wound dehiscence, which was managed conservatively and primary delayed closure after 4 weeks. 8 months postoperatively the patient has a good evolution and an acceptable functional and aesthetic result, without recurrence, which has allowed his reintegration into work and a good physical-psycho-emotional balance. Conclusion. The objective of this fl ap is to provide coverage to the ischial area without aff ecting adjacent structures, which requires a broad knowledge of the anatomy of the femoral region, as well as the local and regional fl aps that can be used for reconstruction. Nowadays this fl ap is an eff ective therapeutic option for the treatment of refractary ischial ulcers in plastis suergery centers without microsurgery.

[Extracapsular hepatic adenoma. Case report and literature review]. / Adenoma hepático extracapsular. Reporte de un caso y revisión de la bibliografía.

BACKGROUND: Hepatic adenomas are uncommon epithelial tumours. They usually appear in women between 20 and 44 years old. They are commonly located in the right hepatic lobe and are typically solitary masses. Multiple adenomas can present in patients with prolonged use of oral contraceptive pills, glycogen storage diseases and hepatic adenomatosis. CLINICAL CASE: A 35 year-old woman without any significant past medical history, with a chief complaint that started in December 2012 with oppressive, mild intensity abdominal pain located in right upper quadrant in the abdomen on deep palpation. With an abdominal ultrasound showing a mass of 91×82×65cm located in the right flank, isoechogenic with internal vascularity. Contrast computed tomography scan showing an ovoid tumour with circumscribed borders, with heterogenic intense reinforcement and displacement of adjacent structures with dimensions of 88×71×80cm. In laparotomy, excision of the tumour and cholecystectomy with the trans surgical findings of an 8cm tumour with a pedicle containing one artery and one vein coming from the hepatic free border with strong adhesions to the gallbladder. Pathologic diagnosis: Extracapsular hepatic adenoma. CONCLUSIONS: Incidence of hepatic adenomas has increased in the last decades, in a parallel fashion with the introduction of oral contraceptive pills, showing association with glycogen storage diseases and to a lesser degree with diabetes and pregnancy. Diagnosis is clinical with the aid of imaging studies. Prognosis of hepatic adenomas is not well established, therefore, management depends on symptoms, size, number, location and certainty of diagnosis.

Laparoscopic resection of a gastric schwannoma: A case report.

INTRODUCTION: Mesenchymal tumors of the gastrointestinal tract are a group spindle cell tumors which include gastrointestinal stromal tumors, leiomyomas, leiomyosarcomas and schwannomas (Nishida and Hirota, 2000). Schwannomas generally present as a slow and asymptomatic growing mass in the gastrointestinal tract typically arising in the gastric submucosa accounting for up to 0.2% of gastric tumors (Melvin and Wilkinson, 1993; Sarlomo-Rikala M, Miettinen, 1995). TREATMENT: with negative surgical margin resection (as approached in this case) is considered the standard treatment. PRESENTATION OF CASE: A 60-year-old woman was referred to our general surgery service for dyspepsia. During her evaluation a gastric mass was incidentally found on upper GI endoscopy which showed a submucosal exophytic neoplasm at the gastric antrum. The patient was discharged following an uneventful recovery from a successful surgical laparoscopic tumor resection. DISCUSSION: Schwannomas are benign neurogenic tumors that originate from Schwann cells. They commonly occur in the head and neck but are rare in the GI tract (Menno et al., 2010). The differential diagnosis between gastric schwannomas and GISTs can be difficult in the preoperative assessment. With the advent of immunohistochemical staining techniques it is now possible to make a differential diagnosis based on their distinctive immunophenotypes. Gastric schwannomas are consistently positive for S-100 protein and negative for c-kit; conversely, 95% of GISTs are positive for c-kit and negative for S-100 protein in up to 98 to 99% of the cases. CONCLUSION: Gastric schwannomas should be included in the differential diagnosis of any gastric submucosal mass. Negative margin resection as seen with this patient is the standard surgical treatment as there is low malignant transformation potential.
