How do young surgeons understand and grasp the new concepts, new techniques, and recent progress of hernia and abdominal wall surgery? / 中华外科杂志

With the development of modern surgery, the field of hernia and abdominal wall surgery is undergoing a transformative change, and new techniques, new concepts, and recent progress are being updated, which have motivated the high-quality development of the discipline. In the past two decades, the development of hernia and abdominal wall surgery in China has been recognized by international peers. Many young surgeons have gradually become the main force in the treatment of hernia and leaders in surgical technique. The innovation and development of discipline will never terminate; young surgeons as the main force should seriously think about how to improve their professional qualities. Young surgeons are interested in the innovation of surgical techniques and need to push for a traditional operation on the one hand and an innovative operation on the other. Updates to concepts and acquisition of new materials are more important, which can provide a solid foundation for technological innovation. Young surgeons should start with the basics and classics. Understanding the history and development of new techniques, new concepts and recent progress, and grasping indications of clinical application, is the important part of growing up for young surgeons, which can make surgical treatment more standardized, benefit patients, and promote the progress of Chinese specialized medical education.

Re-discussion on the comprehensive treatment strategy of complex ventral hernia from the perspective of intraperitoneal pressure / 中华外科杂志

Complex ventral hernia refers to a large hernia that is complicated by a series of concurrent conditions. Change in intra-abdominal pressure is one of the main pathways through which various factors exert an impact on perioperative risk and postoperative recurrence. Taking abdominal pressure reconstruction as the core, the treatment strategy for complex abdominal hernia can be formulated from three aspects: improving patients' tolerance, expanding abdominal cavity volume, and reducing the volume of abdominal contents. Improving patients' tolerance includes abdominal wall compliance training and progressive preoperative pneumoperitoneum. To expand the volume of the abdominal cavity, implanting hernia repair materials, component separation technique, autologous tissue transplantation, component expend technique, and chemical component separation can be used. Initiative content reduction surgery and temporary abdominal closure may be performed to reduce the volume of abdominal contents. For different cases of complex ventral hernia, personalized treatment measures can be safely and feasibly adopted depending on the condition of the patients and the intra-abdominal pressure situation.

Opportunities and challenges for the high-quality development of hernia and abdominal wall surgery in China / 中华外科杂志

Hernia and abdominal wall surgery is a relatively new subspecialty in surgery. Although it started late in China, after 25 years of rapid development, it has made remarkable achievements and has become an important part of surgery, laying a solid foundation for the further development of the discipline. At the same time, one should also be soberly aware of the present deficiencies in this field. The development of the field should be more detailed and in-depth from the following aspects: correct understanding of new concepts of hernia and abdominal wall surgery, establishment of hernia patient registration and quality control system, technological innovation and development of technical equipment, especially the expansion of robot surgical systems, materials science progression to hernia and abdominal wall surgery. Faced with this challenge, China is expected to achieve high-quality development in the field of hernia and abdominal surgery.

OBJECTIVE@#To summarize the research progress of surgical technique and immunosuppressive regimen of abdominal wall vascularized composite allograft transplantation in animals and clinical practice.@*METHODS@#The literature on abdominal wall transplantation at home and abroad in recent years was extensively reviewed and analyzed.@*RESULTS@#This review includes animal and clinical studies. In animal studies, partial or total full-thickness abdominal wall transplantation models have been successfully established by researchers. Also, the use of thoracolumbar nerves has been described as an important method for functional reconstruction and prevention of long-term muscle atrophy in allogeneic abdominal wall transplantation. In clinical studies, researchers have utilized four revascularization techniques to perform abdominal wall transplantation, which has a high survival rate and a low incidence of complications.@*CONCLUSION@#Abdominal wall allotransplantation is a critical reconstructive option for the difficulty closure of complex abdominal wall defects. Realizing the recanalization of the nerve in transplanted abdominal wall to the recipient is very important for the functional recovery of the allograft. The developments of similar research are beneficial for the progress of abdominal wall allotransplantation.

A prospective study on the expansion rule of the directional skin and soft tissue expander in abdominal scar reconstruction / 中华烧伤杂志

Objective: To observe the expansion rule of directional skin and soft tissue expander (hereinafter referred to as expander) in abdominal scar reconstruction. Methods: A prospective self-controlled study was conducted. Twenty patients with abdominal scar who met the inclusion criteria and admitted to Zhengzhou First People's Hospital from January 2018 to December 2020 were selected by random number table method, including 5 males and 15 females, aged 12-51 (31±12) years, with 12 patients of type Ⅰ scar and 8 patients of type Ⅱ scar. In the first stage, two or three expanders with rated capacity of 300-600 mL were placed on both sides of the scar, of which at least one expander had rated capacity of 500 mL (as the follow-up observation object). After the sutures were removed, water injection treatment was started, with the expansion time of 4 to 6 months. After the water injection volume reached 2.0 times of the rated capacity of expander, abdominal scar excision+expander removal+local expanded flap transfer repair was performed in the second stage. The skin surface area at the expansion site was measured respectively when the water injection volume reached 1.0, 1.2, 1.5, 1.8, and 2.0 times of the rated capacity of expander, and the skin expansion rate of the expansion site at corresponding multiples of expansion (1.0, 1.2, 1.5, 1.8, and 2.0 times) and adjacent multiple intervals (1.0-1.2, 1.2-1.5, 1.5-1.8, and 1.8-2.0 times) were calculated. The skin surface area of the repaired site at 0 (immediately), 1, 2, 3, 4, 5, and 6 months after operation, and the skin shrinkage rate of the repaired site at different time points (1, 2, 3, 4, 5, and 6 months after operation) and different time periods (0-1, 1-2, 2-3, 3-4, 4-5, and 5-6 months after operation) were calculated. Data were statistically analyzed with analysis of variance for repeated measurement and least significant difference-t test. Results: Compared with the expansion of 1.0 time ((287.6±2.2) cm2 and (47.0±0.7)%), the skin surface area and expansion rate of the expansion site of patients ((315.8±2.1), (356.1±2.8), (384.9±1.6), and (386.2±1.5) cm2, (51.7±0.6)%, (57.2±0.6)%, (60.4±0.6)%, and (60.5±0.6)%) were significantly increased when the expansion reached 1.2, 1.5, 1.8, and 2.0 times (with t values of 46.04, 90.38, 150.14, 159.55, 45.11, 87.83, 135.82, and 118.48, respectively, P<0.05). Compared with the expansion of 1.2 times, the skin surface area and expansion rate of the expansion site of patients were significantly increased when the expansion reached 1.5, 1.8, and 2.0 times (with t values of 49.82, 109.64, 122.14, 144.19, 49.51, and 105.85, respectively, P<0.05). Compared with the expansion of 1.5 times, the skin surface area and expansion rate of the expansion site of patients were significantly increased when the expansion reached 1.8 times (with t values of 38.93 and 39.22, respectively, P<0.05) and 2.0 times (with t values of 38.37 and 38.78, respectively, P<0.05). Compared with the expansion of 1.8 times, the skin surface area and expansion rate of the expansion site of patients both had no statistically significant differences when the expansion reached 2.0 times (with t values of 4.71 and 4.72, respectively, P>0.05). Compared with the expansion of 1.0-1.2 times, the skin expansion rate of the expansion site of patient was significantly increased when the expansion reached 1.2-1.5 times (t=6.95, P<0.05), while the skin expansion rate of the expansion site of patient was significantly decreased when the expansion reached 1.5-1.8 and 1.8-2.0 times (with t values of 5.89 and 40.75, respectively, P<0.05). Compared with the expansion of 1.2-1.5 times, the skin expansion rate of the expansion site of patient was significantly decreased when the expansion reached 1.5-1.8 and 1.8-2.0 times (with t values of 10.50 and 41.92, respectively, P<0.05). Compared with the expansion of 1.5-1.8 times, the skin expansion rate of the expansion site of patient was significantly decreased when the expansion reached 1.8-2.0 times (t=32.60, P<0.05). Compared with 0 month after operation, the skin surface area of the repaired site of patient at 1, 2, 3, 4, 5, and 6 months after operation was significantly decreased (with t values of 61.66, 82.70, 96.44, 102.81, 104.51, and 102.21, respectively, P<0.05). Compared with 1 month after operation, the skin surface area of the repaired site of patient was significantly decreased at 2, 3, 4, 5, and 6 months after operation (with t values of 37.37, 64.64, 69.40, 72.46, and 72.62, respectively, P<0.05), while the skin shrinkage rate was significantly increased (with t values of 32.29, 50.00, 52.67, 54.76, and 54.62, respectively, P<0.05). Compared with 2 months after operation, the skin surface area of the repaired site of patient was significantly decreased at 3, 4, 5, and 6 months after operation (with t values of 52.41, 60.41, 70.30, and 65.32, respectively, P<0.05), while the skin shrinkage rate was significantly increased (with t values of 52.97, 59.29, 69.68, and 64.50, respectively, P<0.05). Compared with 3 months after operation, the skin surface area of the repaired site of patient was significantly decreased at 4, 5, and 6 months after operation (with t values of 5.53, 38.00, and 38.52, respectively, P<0.05), while the skin shrinkage rate was significantly increased (with t values of 25.36, 38.59, and 37.47, respectively, P<0.05). Compared with 4 months after operation, the skin surface area (with t values of 41.10 and 50.50, respectively, P>0.05) and skin shrinkage rate (with t values of 48.09 and 50.00, respectively, P>0.05) of the repaired site of patients at 5 and 6 months after operation showed no statistically significant differences. Compared with 5 months after operation, the skin surface area and skin shrinkage rate of the repaired site of patient at 6 months after operation showed no statistically significant differences (with t values of 9.40 and 9.59, respectively, P>0.05). Compared with 0-1 month after operation, the skin shrinkage rate of the repaired site of patient at 1-2, 2-3, 3-4, 4-5, and 5-6 months after operation was significantly decreased (with t values of 13.56, 40.00, 49.21, 53.97, and 57.68, respectively, P<0.05). Compared with 1-2 months after operation, the skin shrinkage rate of the repaired site of patients at 2-3, 3-4, 4-5, and 5-6 months after operation was significantly decreased (with t values of 12.37, 27.72, 30.16, and 31.67, respectively, P<0.05). Compared with 2-3 months after operation, the skin shrinkage rate of the repaired site of patients at 3-4, 4-5, and 5-6 months after operation was significantly decreased (with t values of 33.73, 41.31, and 54.10, respectively, P<0.05). Compared with 3-4 months after operation, the skin shrinkage rate of the repaired site of patient at 4-5 and 5-6 months after operation showed no statistically significant differences (with t values of 10.90 and 23.60, respectively, P>0.05). Compared with 4-5 months after operation, the skin shrinkage rate of the repaired site of patient at 5-6 months after operation showed no statistically significant difference (t=20.90, P>0.05). Conclusions: The expander can effectively expand the abdominal skin, thus repairing the abdominal scar deformity. Maintained expansion for one month after the water injection expansion reaches 1.8 times of the rated capacity of the expander can be set as a phase Ⅱ operation node.

Dermolipectomía por lipodistrofia abdominal grave en obesidad mórbida / Dermolipectomy for severe abdominal lipodystrophy in morbid obesity

RESUMEN La obesidad y el sobrepeso se definen como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud. Es una enfermedad crónica de origen multifactorial, que como consecuencia ocasiona problemas higiénicos, discapacidad funcional y alteración de la calidad de vida. La dermolipectomía abdominal es una técnica quirúrgica que constituye la única opción para el tratamiento de pacientes con panículo adiposo prominente; de esa forma se logra disminuir las complicaciones y se reintegra socialmente al paciente que, a causa del enorme faldón abdominal, estuvo limitado por muchos años. Presentamos el caso de una paciente de 53 años con lipodistrofia abdominal grave, que llegaba a ambos tobillos con afectación cutánea, y discapacidad para realizar actividades diarias, resuelta con dermolipectomía abdominal y resección de 29 kg de tejido dermograso. Se realizará, además, una revisión bibliográfica del tema.

ABSTRACT Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. It is a chronic disease caused by multiple factors, which results in hygienic issues, functional disability and impaired quality of life. Abdominal dermolipectomy is the only surgical option for the treatment of patients with prominent panniculus morbidus, thus reducing complications and providing social reintegration for the patient who has been limited for many years due to the enormous abdominal panniculus. We report the case of a 53-year-old female patient with severe abdominal lipodystrophy with coverage of both ankles, skin involvement, and disability to perform daily activities, that was managed with abdominal dermolipectomy and resection of 29 kg of dermo-adipose tissue. Bibliographic research is also presented.

Absceso del psoas ilíaco secundario a un tumor de colon izquierdo fistulizado al retroperitoneo: caso clínico y análisis de la literatura / Iliopsoas abscess resulting from penetrating left colon cancer to the retroperitoneum: case report and literature review / Abscesso do iliopsoas secundário a tumor de cólon esquerdo fistulizado para o retroperitônio: caso clínico e análise da literatura

Los abscesos del psoas ilíaco secundarios a un tumor de colon fistulizado son excepcionales y potencialmente graves. La mayoría son adenocarcinomas de tipo mucinoso. Su tratamiento es complejo ya que, para lograr una resección oncológica pretendidamente curativa, es necesario realizar una resección ampliada con mayor morbimortalidad. Presentamos el caso de una paciente con un adenocarcinoma mucinoso de colon izquierdo fistulizado al músculo ilíaco y la pared anterolateral del abdomen en la que se realizó una resección multivisceral que incluyó el colon izquierdo, el músculo y la cresta ilíaca y parte de la pared anterolateral del abdomen.

Iliopsoas abscess secondary to perforation of colon cancer is an extremely rare and potentially life-threatening condition. Most tumors are mucinous adenocarcinomas. Its treatment its complex, as most patients need radical extended resections to achieve good oncological results, which are in turn, graved with higher morbidity and mortality. We present the case of a patient with a left colon mucinous adenocarcinoma penetrating to the iliopsoas muscle and the anterolateral abdominal wall that required a multivisceral resection including left colon, iliac muscle and crest and part of the anterolateral abdominal wall.

Abscessos do iliopsoas secundários a um tumor de cólon fistulizado são raros e potencialmente graves. A maioria são adenocarcinomas do tipo mucinoso. Seu tratamento é complexo, pois, para se obter uma ressecção oncológica supostamente curativa, é necessário realizar uma ressecção ampliada com maior morbimortalidade. Apresentamos o caso de um paciente com adenocarcinoma mucinoso de cólon esquerdo fistulizado para o músculo ilíaco e parede ântero-lateral do abdome no qual foi realizada ressecção multivisceral que incluiu cólon esquerdo, músculo e crista ilíaca e parte do a parede anterolateral do abdome.

Endometriosis de la pared abdominal en relación con cicatriz de operación cesárea: serie de casos / Abdominal wall endometriosis in relation to cesarean section scar: number of cases

RESUMEN: La endometriosis (E), se define como presencia de glándulas endometriales y estroma fuera del útero. Ocasionalmente se presenta como masa sensible en la pared abdominal (PA), en relación con una cicatriz quirúrgica (EPA). Aunque el tratamiento es quirúrgico, existe poca información respecto de la morbilidad postoperatoria (MPO) y la recurrencia de la EPA. El objetivo de este estudio fue determinar MPO y recurrencia en pacientes resecadas quirúrgicamente por EPA. Serie de casos de pacientes con EPA, sometidos a cirugía de forma consecutiva, en Clínica RedSalud Mayor, entre 2011 y 2021. Las variables resultados MPO y recurrencia. Otras variables de interés fueron: tiempo quirúrgico, estancia hospitalaria y mortalidad. Las pacientes fueron seguidas de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. Se intervinieron 14 pacientes, con una mediana de edad de 33 años. La medianas del tiempo quirúrgico y estancia hospitalaria; fueron 55 min y 2,5 días respectivamente. La MPO fue 14,2 % (2 casos). Con una mediana de seguimiento de 31 meses, no se verificó recurrencia. Aunque la EPA es poco común, estas lesiones deben sospecharse en mujeres en edad reproductiva con masa palpable en relación con una cicatriz de cirugía ginecológica u obstétrica. Los resultados obtenidos, en términos de MPO y recurrencia, fueron similares a series internacionales.

SUMMARY: Endometriosis (E) is defined as the presence of endometrial glands and endometrial stroma outside the uterus. Occasionally it presents as a sensitive mass in the abdominal wall (AW), in relation to a surgical scar (AWE). Although the treatment is surgical, there is scarce information regarding postoperative morbidity (POM) and recurrence of AWE. The aim of this study was to determine POM and recurrence in patients surgically resected by AWE. Case series of patients with AWE, consecutively submitted to surgery, at RedSalud Mayor Clinic, between 2011 and 2021. Outcome variables were POM and recurrence. Other variables of interest were surgical time, hospital stay and mortality. Patients were followed-up clinically. Descriptive statistics were used, applying central tendency and dispersion measures. 14 patients were intervened, with a median age of 33 years. Median of surgical time and hospital stay were 55 min and 2,5 days respectively. POM was 14.2 % (2 cases). With a median follow-up of 31 months no recurrence was verified. Although AWE is uncommon, these lesions should be suspected in women in fertile age with a palpable mass associated with a scar from gynecologic or obstetric surgery. The results obtained, in terms of POM and recurrence, were like international series.

Tratamiento quirúrgico de la fibromatosis agresiva en relación con cesárea previa / Surgical treatment of aggressive fibromatosis in relation to previous cesarean section

Introducción. Los tumores desmoides son lesiones de los tejidos blandos, histológicamente benignas, poco frecuentes y con gran agresividad local y carencia de potencial metastásico. Se relacionan estrechamente con antecedentes traumáticos o quirúrgicos, como la cesárea, y su tratamiento generalmente es quirúrgico. Métodos. Presentamos una serie de tres pacientes intervenidas en nuestro centro durante el año 2020. Se revisan sus antecedentes y se describe su tratamiento. Resultados. En todas nuestras pacientes se encontró algún antecedente quirúrgico, dos cesáreas y una resección de un disgerminoma. El tratamiento empleado fue la resección quirúrgica con márgenes libres y reparación del defecto mediante malla. Conclusiones. El tumor desmoide es una patología poco frecuente, su diagnóstico se realiza mediante exámenes imagenológicos y se confirma con el estudio histológico; es importante hacer el diagnóstico diferencial con el sarcoma. La cirugía radical sigue siendo el tratamiento de elección, aunque algunos autores proponen el tratamiento conservador.

Introduction. Desmoid tumors are soft tissue lesions, histologically benign, rare and with great local aggressiveness and lack of metastatic potential. They are closely related to traumatic or surgical history such as caesarean section. Their treatment is generally surgical. Methods. We present a case series of three patients operated on in our center during the year 2020. Their history is reviewed and their type of treatment is presented. Results. In all our patients, surgical history was found (two caesarean sections and one resection of a dysgerminoma). The treatment used was surgical resection with free margins and mesh repair of the defect. Conclusions. Desmoid tumor is a rare pathology; its diagnosis is made by imaging studies, and confirmed by histology. It is important to make a differential diagnosis with sarcoma. Radical surgery remains the treatment of choice, although some authors propose conservative treatment.

Al quinto día del posoperatorio mostró signos peritoneales y la exploración confirmó peritonitis fecaloidea por dehiscencia de sutura de colon. Se lavó cavidad y se le ejecutó colostomía tipo Devine. La pérdida masiva de pared abdominal obligó a emplear una plicatura de la bolsa Bogotá para aproximar ambos colgajos, se obtuvo aproximación paulatina hasta la síntesis de la pared. Conclusiones: El abdomen catastrófico es una condición grave y de difícil tratamiento. La bolsa Bogotá es una alternativa viable para esta condición y modificada con plicaturas paulatinas permite el acercamiento de los dos colgajos cutáneos y garantiza el cierre de la pared abdominal, además de ser una técnica fácil de usar y económica(AU)

Introduction: Closure with massive loss of abdominal wall tissue is a challenge in surgery. Objective: To report a case of difficult abdominal closure where the Bogotá bag technique was used until the approximation of the cutaneous, muscular and aponeurotic planes was achieved. Clinical case report: This patient was received in the emergency room with a perforating-cutting wound in the left lumbar fossa. In the intervention, hemoperitoneum was found due to splenic and diaphragmatic injury and section of the splenic flexure of the colon. Splenectomy, left pleurostomy and colonic injury raffia were performed. After five hours, the patient was operated again due to signs of shock. We found a retroperitoneal hematoma and a complete section of the upper pole of the left kidney. It was decided to perform left nephrectomy. On the fifth postoperative day, this patient showed peritoneal signs and examination confirmed fecal peritonitis due to dehiscence of the colon suture. Cavity was washed and a Devine-type colostomy was performed. The massive loss of the abdominal wall made it necessary to use a plication of the Bogotá bag to approximate both flaps, a gradual approximation was obtained until the synthesis of the wall. Conclusions: The catastrophic abdomen is a serious condition that is difficult to treat. The Bogotá bag is a viable alternative for this condition and modified with gradual plications, it allows the two skin flaps to approach each other and guarantees the closure of the abdominal wall, in addition to being an easy-to-use and economical technique(AU)

Short and Medium-term Outcomes of Omphalocele and Gastroschisis: A Survey from a Tertiary Center / Resultados a curto e médio prazo do onfalocelo e gastrosquisis: uma investigação de um centro terciário

Abstract Objective To characterize and compare the outcomes of omphalocele and gastroschisis from birth to 2 years of follow-up in a recent cohort at a tertiary center. Methods This is a retrospective clinical record review of all patients with gastroschisis and omphalocele admitted to the Neonatal Intensive Care Unit between January 2009 and December 2019. Results There were 38 patients, 13 of whom had omphalocele, and 25 of whom had gastroschisis. Associated anomalies were present in 6 patients (46.2%) with omphalocele and in 10 (41.7%) patients with gastroschisis. Compared with patients with omphalocele, those with gastroschisis had younger mothers (24.7 versus 29.6 years; p=0.033), were born earlier (36 versus 37 weeks, p=0.006), had lower birth weight (2365±430.4 versus 2944.2±571.9 g; p=0.001), and had a longer hospital stay (24 versus 9 days, p=0.001). The neonatal survival rate was 92.3% for omphalocele and 91.7% for gastroschisis. Thirty-four patients were followed-up over a median of 24 months; 13 patients with gastroschisis (59.1%) and 8 patients with omphalocele (66.7%) had at least one adverse event, mainly umbilical hernia (27.3% vs 41.7%), intestinal obstruction (31.8% vs 8.3%), or additional surgical interventions (27.3% vs 33.3%). Conclusion Despite the high proportion of prematurity, low birth weight, and protracted recovery, gastroschisis and omphalocele (without chromosomal abnormalities) may achieve very high survival rates; on the other hand, complications may develop in the first years of life. Thus, a very positive perspective in terms of survival should be transmitted to future parents, but they should also be informed that substantial morbidity may occur in the medium term.

Resumo Objetivo Caracterizar e comparar os desfechos do onfalocelo e gastrosquisis desde o nascimento até aos 2 anos de seguimento numa coorte recente de um centro terciário. Métodos Este é um estudo retrospectivo em que foi feita uma revisão dos registos clínicos de todos os pacientes com gastrosquisis e onfalocelo que foram internados na unidade de cuidados intensivos neonatais, entre janeiro de 2009 e dezembro de 2019. Resultados Identificamos 38 pacientes, 13 dos quais tinham onfalocelo e 25 dos quais tinham gastrosquisis. Anomalias associadas estavam presentes em 6 pacientes (46.2%) com onfalocelo e 10 (41.7%) com gastrosquisis. Comparativamente com os pacientes com onfalocelo, os pacientes com gastrosquisis tinham mães mais jovens (24.7 versus 29.6 anos; p=0.033), nasceram mais precocemente (36 versus 37 semanas, p=0.006), com menor peso ao nascimento (2,365±430.4 versus 2,944.2±571.9 g; p=0.001), e o internamento teve uma duração mais longa (24 versus 9 dias, p=0.001). A taxa de sobrevivência neonatal foi de 92.3% para o onfalocelo e 91.7% para a gastrosquisis. Trinta e quatro pacientes foram seguidos durante umtempo mediano de seguimento de 24meses: 13 com gastrosquisis (59.1%) e 8 com onfalocelo (66.7%) apresentaram pelo menos um evento adverso, sobretudo hérnia umbilical (27.3% vs 41.7%), obstrução intestinal (31.8% vs 8.3%) ou intervenções cirúrgicas adicionais (27.3% vs 33.3%). Conclusão Apesar da alta proporção de prematuridade, de baixo peso e de recuperação lenta, os gastrosquisis, assim como os onfalocelos (sem anomalias cromossómicas), podem ter uma taxa de sobrevivência muito alta; por outro lado, nos primeiros anos de vida, podem surgir complicações não desprezíveis. Assim, aos futuros pais pode ser transmitida uma perspectiva muito positiva em termos de sobrevivência, embora eles também devam ser informados de que pode ocorrermorbidade substancial no médio prazo.

Preoperative botulinum A toxin as an adjunct for abdominal wall reconstruction: a single-center early experience at an Academic Center in New York / Toxina botulínica A pré-operatória como adjuvante na reconstrução da parede abdominal: experiência inicial em Centro Acadêmico em Nova York

ABSTRACT Introduction: the botulinum toxin A (BTA) has been used to achieve a chemical component separation, and it has been used with favorable outcomes for the repair of complex ventral hernia (CVH) with and without loss of domain (LD). The aim of this study is to describe our early experience with the chemical component separation in the United Sates. Methods: a retrospective observational study of all patients who underwent ventral hernia repair for CVH with or without LD between July 2018 and June 2020. Preoperative BTA was injected in all patients via sonographic guidance bilaterally, between the lateral muscles to achieve chemical denervation before the operation. Patient demographics, anatomical location of the hernia, perioperative data and postoperative data are described. Results: 36 patients underwent this technique before their hernia repair between July 2018 to June 2020. Median age was 62 years (range 30-87). Median preoperative defect size was 12cm (range 6-25) and median intraoperative defect size was 13cm (range 5-27). Median preoperative hernia sac volume (HSV) was 1338cc (128-14040), median preoperative abdominal cavity volume (ACV) was 8784cc (5197-18289) and median volume ration (HSV/ACV) was 14%. The median OR time for BTA administration was 45 minutes (range 28-495). Seroma was the most common postoperative complication in 8 of the patients (22%). Median follow up was 43 days (range 0-580). Conclusion: preoperative chemical component separation with BTA is a safe and effective adjunct to hernia repair in CVH repairs where a challenging midline fascial approximation is anticipated.

RESUMO Introdução: a toxina botulínica A (TBA) tem sido usada para alcançar a separação química dos componentes, com resultados favoráveis para o reparo de hérnias ventrais complexas (HVC) com ou sem perda de domínio (PD). O objetivo deste estudo é descrever nossa experiência inicial com a separação química dos componentes nos Estados Unidos. Métodos: estudo retrospectivo observacional com todos os pacientes submetidos a reparo de hérnia ventral complexa com ou sem PD entre julho de 2018 e junho de 2020. A TBA pré-operatória foi injetada em todos os pacientes, guiada por ultrassonografia, bilateralmente entre os músculos laterais para alcançar a denervação química antes da operação. Dados demográficos dos pacientes, local da hérnia, dados peri-operatórios e pós-operatórios são descritos. Resultados: 36 pacientes foram submetidos a esta técnica antes do reparo da hérnia. A idade mediana foi 62 anos (30-87). O tamanho mediano pré-operatório do defeito herniário foi 12cm (6-25) e o defeito mediano intra-operatorio foi 13cm (5-27). O volume mediano do saco herniário pré-operatório foi 1.338mL (128-14.040), o volume mediano da cavidade abdominal pré-operatório foi 8.784 (5.197-18.289) mL e a razão dos volumes foi 14%. A duração mediana da operação para aplicação da TBA foi 45 minutos (28-495). O seroma foi a complicação mais comum no pós-operatório, em oito pacientes (22%). O seguimento pós-operatório mediano foi de 43 dias (0-580). Conclusão: a separação pré-operatória de componentes com TBA é tratamento adjuvante seguro e eficaz em reparos de HVC em que aproximação da fáscia é antecipadamente desafiadora.
