RESUMEN Fundamento: la monitorización de la presión intraabdominal constituye un parámetro importante en las pacientes sometidas a dermolipectomía abdominal. Objetivo: determinar las variaciones de la presión intraabdominal en las pacientes sometidas a dermolipectomía. Métodos: se realizó un estudio descriptivo, de corte transversal para determinar las variaciones de la presión intraabdominal en pacientes sometidas a dermolipectomía; en el servicio de Cirugía Plástica del Hospital Universitario Manuel Ascunce Domenech de la provincia Camagüey en el período comprendido desde enero de 2018 hasta noviembre de 2019. Se estudiaron 22 pacientes en quienes se evaluaron la edad, el tipo de lipodistrofia abdominal, las cifras de PIA, el índice de masa corporal y la cantidad de centímetros plicados en la pared abdominal anterior. Resultados: las pacientes comprendidas en las edades entre 29 y 48 años fueron las que predominaron en el estudio. La mayoría tenían lipodistrofia grado II, 11 pacientes para un 50 %. Las pacientes con sobre peso (10) que fueron la mayoría en el estudio, de ellas seis registraron PIA grado I. La relación entre los diferentes niveles de PIA y la plicatura abdominal en centímetros, de las 14 pacientes que mostraron niveles de PIA grado I, a ocho se le plicó entre ocho y 10 cm y a cuatro de las pacientes 11 cm o más. Conclusiones: la mayoría de las pacientes operadas tenían edades comprendidas entre 29 y 48 años. Existió un predominio de lipodistrofia grado II en las pacientes trastadas. El índice de masa corporal y la cantidad de centímetros plicados de la pared abdominal influyen de manera directa en el incremento de los niveles de PIA.

ABSTRACT Background: the monitoring of the intra-abdominal pressure constitutes an important parameter in the patients submitted to abdominal dermolipectomy. Objective: to determine the variations of the intra-abdominal pressure in the patients submitted to dermolipectomy. Methods: a descriptive, cross-section study to determine the variations of the intra-abdominal pressure in patients submitted to dermolipectomy was carried out; in the service of Plastic Surgery of the Hospital Universitario Manuel Ascunce Domenech of the city of Camagüey in the period understood since January, 2018 to November, 2019. They studied twenty two patients in those who they evaluated the age, the type of abdominal lipodystrophy, the amounts of PIA, the Body Mass Index, and the quantity of plicate centimeters in the previous abdominal wall. Results: the patients understood in the ages between twenty nine to forty eight years were the ones that predominated in this study. The majority had lipodystrophy degree two, 11 patients for a 50 %. The patients with overweight (ten patients) that were the majority in this study, of them six patients registered PIA degree I. The relation between PIA's different levels and the abdominal plication in cm, of the patient fourteen that showed levels of PIA degree I, to eight were reduced between eight ten cm and to four of the patients eleven cm or more. Conclusions: most of the operated patients had ages understood between twenty nine to forty eight years. There was a predominance of lipodystrophy degree two in the treated patients. The Body Mass Index and the quantity of plicate centimeters of the abdominal wall have influence right into the increment of the levels of PIA.

Treatment analysis and epidemiological study on external abdominal hernia based on the Hernia Registry in China / 中华消化外科杂志

In the past, hernia and abdominal wall surgery has been ignored, which may endanger the life of patients due to untimely treatment. In 1997, the concept of tension-free hernia repair was introduced to China. Chinese hernia and abdominal wall surgery entered a new era and developed rapidly. In 2015, scholars in China decided to create our own Hernia Registry. In 2017, Hernia Registry was officially released, and the Chinese Hernia Surgery Alliance was established in the same period. The Chinese Hernia Registry has became the second largest Hernia clinical registry database in the world. Although the follow-up rate needs to be improved, it is possible to have a preliminary understanding and analysis of the incidence of hernia disease in China. There are many difficulties in its application, and it requires the multi-level coordination and long-term commitment. The authors hope that through this work, the diagnosis and treatment of hernia and abdominal wall can be improved, and the ability of communication and cooperation at home and abroad will be enhanced, benefiting the general population of hernia patients.

Current status and preliminary data analysis of Chinese hernia registry and follow-up system / 中华消化外科杂志

Hernia is a most common disease requiring surgery.In recent years,the number of newly emerging patients with inguinal hernia is 300-400 million cases per year and surgical amount of tension-free hernia repair surpasses 150 million cases per year in China.However,overall effects of hernia treatment are unsatisfactory and complications such as postoperative infection,chronic pain and hernia recurrence have troubled clinical surgeons and patients.How to improve diagnosis and treatment of hernia and abdominal wall surgery,how to achieve clinical data accumulation with which to evaluate,monitor and normalize medical behavior,how to realize polycentric data sharing,Chinese hernia registry and follow-up system provides effective helps for above mentioned aspects,especially lays a solid foundation for clinical standardization,quality monitoring,scientific research enhancement,ultimately provides mutual rewarding for both patients and clinical surgeons.

Innovation and development of hernia and abdominal wall surgery in China / 中华消化外科杂志

In recent 20 years,the hernia and abdominal wall surgery in China was in a fast developing stage.The paper published in Issue 5,2017 of the Lancet gave scores for 25-year development of 32 diseases,and a high score of 99 points on diagnosis and treatment of inguinal hernia in China was in fourth place globally,which has far outstripped the other countries of the world.But there is still a wide gap on comprehensive strength between Chinese and international levels.Authors have to make further efforts in many aspects,including the standardization,guideline,basic research,innovation and development of surgical techniques,registration system and quality control of hernia and abdominal wall surgery in China,in order to encourage and inspire surgeons to have continuously inheritance,development and innovation in the achievement and historical problems.

Aplicabilidade do retalho anterolateral da coxa pediculado nas reconstruções complexas da parede abdominal em oncologia: relato de 2 casos / Applicability of the pedicled anterolateral thigh flap in complex reconstructions of the abdominal wall in oncology: report of 2 cases

INTRODUÇÃO: Há um grande empenho na busca por soluções reconstrutivas para as áreas de perda cutânea ou muscular que exijam cobertura ou preenchimento cavitário estável. O retalho anterolateral da coxa, descrito na China por Song et al. (1984), é considerado por muitos como o retalho ideal nas grandes reconstruções. OBJETIVO: Relatar a aplicabilidade do retalho anterolateral da coxa como recurso versátil nas reconstruções da parede abdominal. MÉTODOS: Dois pacientes foram selecionados para serem submetidos à ressecção tumoral de cólon direito com invasão da parede abdominal pela equipe de cirurgia oncológica em conjunto com a equipe de cirurgia plástica, que foi a responsável pela reconstrução da parede abdominal. Em ambos os casos, utilizou-se o retalho anterolateral da coxa pediculado, que foi transposto para o defeito após a ressecção parcial da parede abdominal no mesmo tempo cirúrgico. Entre as vísceras abdominais e o retalho, foi fixada tela de PROCEEDTM para reforço da parede abdominal. Resultados: Ambos os pacientes tiveram boa evolução pós-operatória e encontram-se em acompanhamento, sem sinais de recidiva tumoral e com boa qualidade de vida. CONCLUSÃO: O retalho anterolateral da coxa mostrou-se recurso útil dentro do arsenal terapêutico reconstrutivo da parede abdominal devido a grandes ressecções tumorais em oncologia.

INTRODUCTION: There is a strong commitment in pursuing reconstructive solutions for areas of skin or muscular loss that require covering or stable cavity filling. The anterolateral thigh flap, described in China by Song et al. (1984), is considered by many as the optimal flap in large reconstructions. OBJECTIVE: To report the applicability of the anterolateral thigh flap, as a versatile resource in reconstructions of the abdominal wall. METHODS: Two patients were submitted to tumoral resection of the right colon with invasion of the abdominal wall by a team of oncologic surgeons in conjunction with the plastic surgery team that was responsible for the reconstruction of the abdominal wall. In both cases, the pedicled anterolateral thigh flap was used, which was transposed to the defect after partial resection of the abdominal wall at the same surgical time. A PROCEEDTM surgical mesh was fixed between the abdominal viscera and the flap to reinforce the abdominal wall. RESULTS: Both patients had good postoperative evolution and are in follow-up, with no signs of tumor recurrence and with a good quality of life. CONCLUSION: The anterolateral thigh flap is a useful resource for the reconstruction of the abdominal wall due to large tumor resections in oncology.

Abdominoplasty with corset plication / Abdominolipoplastia com plicatura em espartilho

Introduction: Abdominoplasty is one of the most common plastic surgery procedures used worldwide. It covers the esthetic appearance and reconstruction of the abdominal wall. Many variations of the incisions, musculofascial repair, and remodeling of the navel have been described. In 1965, Callia performed an incision on the pubis with lateral extensions. In 1967, Pitanguy performed a low horizontal incision with the extremities out and down, and promoted the plication of the rectus abdominis muscles without opening the aponeurosis. Besides demonstrating the ease of implementation and safety of the procedure, the objective of this study was to perform classical abdominoplasty in combination with median and external pararectal plications, also referred to as a corset technique, to recover abdominal wall tension and then liposuction at the end of the procedure to improve abdominal body contour. Methods: Sixty-two women with a mean age of 37 years underwent operation between 2011 and 2013. Results: None of the women in the present study had hematoma, infection, necrosis, or epidermolysis. Late encapsulated seroma was observed in one patient. Five patients had a "dog ear," and eight had unsightly scars but no keloid. All the patients were satisfied with the surgical outcome. Conclusion: The technique described in this study adds two more plications to the classic abdominoplasty, which lead to higher tension in the abdominal wall and more satisfactory esthetic results. Besides being easy to implement, the technique enables lower positioning of the suprapubic transverse incision, which can be easily hidden even with short clothing.

Introdução: Abdominoplastia é um dos procedimentos mais realizados na Cirurgia Plástica mundial. Abrange o aspecto estético e reconstrutor da parede abdominal. Muitas variações das incisões, do reparo musculofascial e da remodelagem do umbigo têm sido descritas. Em 1965, Callia realizou incisão sobre o púbis com prolongamentos laterais. Em 1967, Pitanguy fez incisão horizontal baixa com as extremidades para fora e para baixo e promoveu a plicatura dos músculos retos abdominais sem a abertura da aponeurose. O objetivo deste estudo foi realizar abdominoplastia clássica associada às plicaturas mediana e pararretais externas para recuperar a tensão da parede abdominal - técnica em espartilho - e também à lipoaspiração ao final do procedimento, no intuito de melhorar o contorno corporal abdominal, além de mostrar a facilidade de execução e a segurança do procedimento. Métodos: Foram operadas 62 mulheres no período de 2011 a 2013, com idade média de 37 anos. Resultados: Não houve hematoma, infecção, necrose ou epidermólise no presente estudo. Observou-se a presença de seroma encapsulado tardio em uma paciente. Houve cinco casos de "dog ear", oito de cicatrizes inestéticas, mas nenhuma queloideana. Todas as pacientes sentiramse satisfeitas. Conclusão: Esta técnica agregou mais duas plicaturas musculares à abdominoplastia clássica, levando a uma maior tensão na parede abdominal, com resultado estético mais satisfatório. Conseguiu-se um posicionamento mais baixo da incisão transversal suprapúbica, que pode ser facilmente oculta por roupas menores, além da facilidade de execução.

Use of surgical mesh of different compositions in the correction of the abdominal wall defect in rats / Emprego de telas cirúrgicas de diferentes composições na correção de defeito da parede abdominal de ratos

Objective: To analyze the performance of two surgical meshes of different compositions during the defect healing process of the abdominal wall of rats. Methods: thirty-three adult Wistar rats were anesthetized and subjected to removal of an area of 1.5 cm x 2 cm of the anterior abdominal wall, except for the skin; 17 animals had the defect corrected by edge-to-edge surgical suture of a mesh made of polypropylene + poliglecaprone (Group U - UltraproTM); 16 animals had the defect corrected with a surgical mesh made of polypropylene + polidioxanone + cellulose (Group P - ProceedTM). Each group was divided into two subgroups, according to the euthanasia moment (seven days or 28 days after the operation). Parameters analyzed were macroscopic (adherence), microscopic (quantification of mature and immature collagen) and tensiometric (maximum tension and maximum rupture strength). Results : there was an increase in collagen type I in the ProceedTM group from seven to 28 days, p = 0.047. Also, there was an increase in the rupture tension on both groups when comparing the two periods. There was a lower rupture tension and tissue deformity with ProceedTM mesh in seven days, becoming equal at day 28. Conclusion : the meshes retain similarities in the final result and more studies with larger numbers of animals must be carried for better assessment.

Objetivo: analisar o desempenho de duas telas cirúrgicas de composições diferentes durante o processo de cicatrização de defeito de parede abdominal de ratos. Métodos: trinta e três ratos Wistar, machos adultos foram anestesiados e submetidos à retirada de parede abdominal anterior, exceto pele, com área de 1,5cmx2cm; 17 animais tiveram o defeito corrigido pela sutura borda a borda de tela cirúrgica, composta de polipropileno + poliglecaprone (Grupo U - Ultrapro(r)); 16 animais tiveram defeito corrigido utilizando tela cirúrgica composta de polipropileno + polidioxanone + celulose (Grupo P - Proceed(r)). Cada grupo foi dividido em dois subgrupos, de acordo com o momento da eutanásia (sete dias ou 28 dias após a operação). Foram analisados parâmetros macroscópicos (aderência), microscópicos (quantificação do colágeno maduro e imaturo) e tensiométricos (tensão máxima e força máxima de ruptura). Resultado: houve um aumento do colágeno tipo I no grupo Proceed(r) do período de sete dias para o de 28 dias, com p=0,047. E houve um aumento na tensão de ruptura quando comparados os dois períodos, nas duas telas analisadas. Houve menor tensão de ruptura e deformidade dos tecidos com a tela Proceed(r) em sete dias, levando a uma igualdade com 28 dias. Conclusão: as telas conservam semelhanças no resultado final e mais estudos com número maior de animais devem ser realizados para melhor avaliação.

Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis / Fechamento abdominal temporário com dispositivo tela-zíper para tratamento da sepse intra-abdominal

OBJECTIVE: To present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years); 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

OBJETIVO: Apresentar nossa experiência com reoperações agendadas em 15 pacientes com sepse intra-abdominal. MÉTODOS: foi empregada uma técnica mais eficaz que consiste em fechamento abdominal temporário com uma folha de malha de nylon contendo um zíper. Realizamos as reoperações no centro cirúrgico, sob anestesia geral, com um intervalo médio de 84 horas. A revisão consistiu de desbridamento de material necrosado e lavagem vigorosa da área peritoneal envolvida. A média de idade dos pacientes foi 38,7 anos; 11 pacientes eram do sexo masculino e quatro do sexo feminino. RESULTADOS: Quarenta por cento das infecções foram devido à pancreatite necrosante. Sessenta por cento foram ocasionadas por perfuração intestinal secundária à inflamação, oclusão vascular ou trauma. Foram realizadas 48 reoperações, média de 3,2 operações por paciente. O dispositivo tela-zíper foi deixado no local por uma média de 13 dias. Um estoma intestinal estava presente ao lado do zíper em quatro pacientes e não ocasionou complicação para o paciente. A mortalidade foi 26,6%. Nenhuma fístula resultou dessa técnica. Quando a doença intra-abdominal estava sob controle, o dispositivo de fecho do tipo de rede foi removido, e a fáscia foi fechada em todos os pacientes. Em três pacientes, a ferida foi fechada primariamente, em 12 permitiu-se fechar por intenção secundária. Dois pacientes desenvolveram hérnia: uma incisional e outra na incisão de drenagem. CONCLUSÃO: A nova operação prevista para lavagem manual e desbridamento do abdômen através de uma combinação de tela-zíper em nylon foi rápida, simples e bem tolerada, permitindo uma gestão eficaz da peritonite séptica grave, fácil tratamento das feridas e fechamento primário da parede abdominal.

Revision of loop colostomy under regional anaesthesia and sedation

Patients presenting for emergency abdominal procedures often have medical issues that cause both general anaesthesia and central neuraxial blockade to pose significant risks. Regional anaesthetic techniques are often used adjunctively for abdominal procedures under general anaesthesia, but there is limited published data on procedures done under peripheral nerve or plexus blocks. We herein report the case of a patient with recent pulmonary embolism and supraventricular tachycardia who required colostomy refashioning. Ultrasonography-guided regional anaesthesia was administered using a combination of ilioinguinal-iliohypogastric, rectus sheath and transversus abdominis plane blocks. This was supplemented with propofol and dexmedetomidine sedation as well as intermittent fentanyl and ketamine boluses to cover for visceral stimulation. We discuss the anatomical rationale for the choice of blocks and compare the anaesthetic conduct with similar cases that were previously reported.

New viewpoints of anatomy and therapeutic principles for modern hernia surgery / 中华消化外科杂志

Hernia is a common and frequent disease.Theory of hernia and abdominal wall surgery has been quickly developing since 1970s, since then tension-free repair concept was originated.Continuous development of modern hernia surgery and abdominal wall surgery is based on this concept.New viewpoints include conduction of guideline of diagnosis and treatment for hernia and quality control standard, recognition of anatomy, definition of abdominal wall, concept of basic treatment principle, indication and contraindication for surgical treatment,development and choice of procedures, prevention and therapy of complications, evaluation of postoperative rehabilitation, improvement of quality of life, recurrence rate, appearance, longterm prognosis, etc.This paper describes the latest and important related issues in order to help surgeons to know new concepts, further standardize diagnosis and treatment and finally achieve satisfactory therapeutic efficacy.
