ABSTRACT
Objective:To investigate the application value of transversus abdominis muscle release technique in giant ventral hernia repair.Methods:The retrospective and descriptive study was conducted. The clinical data of 72 patients with giant ventral hernia who were admitted to Beijing Chaoyang Hospital of Capital Medical University from January 2017 to January 2020 were collected. There were 47 males and 25 females, aged from 29 to 79 years, with a median age of 56 years. All patients underwent ventral hernia repair with transversus abdominis muscle release technique and preperitoneal/retro-muscular polypropylene mesh reinforcement. Observation indicators: (1) surgical situations; (2) postoperative complications; (3) hernia-related quality of life. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative complications at postoperative 1, 6 and 12 months. Follow-up was up to January 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison within groups was analyzed using the paired t test. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers. Results:(1) Surgical situations: all 72 patients underwent ventral hernia repair with transversus abdominis muscle release technique and preperitoneal/retro-muscular polypropylene mesh reinforcement successfully. The operation time, volume of intraoperative blood loss and mesh size of the 72 patients were (105±46)minutes, (55±15)mL and (680±225)cm 2, respectively. (2) Postoperative complications: 72 patients were followed up for 12 to 48 months, with a median follow-up time of 16 months. During the follow-up, 7 of the 72 patients were diagnosed with seroma by abdominal computed tomography (CT) scan at postoperative 1 week, the size of which was (460±130)mm 2. The 7 patients with seroma were followed up and results of abdominal CT scan at postoperative 6 months showed that the seroma was completely absorbed. Two of the 72 patients had postoperative intestinal obstruction, which was considered as postoperative paralytic ileus. After conservative treatment, the 2 patients were improved 2 weeks after operation. None of the 72 patients had surgical site infection, intestinal fistula or hernia recurrence. (3) Hernia-related quality of life: the score of hernia-related quality of life of 72 patients before operation and at postoperative 12 months were 40±12 and 73±17, respectively, showing a significant difference ( t=12.527, P<0.05). Conclusion:Transversus abdominis muscle release technique in the giant ventral hernia repair is safe and effective, which can improve hernia-related quality of life of patients.
ABSTRACT
Repair of abdominal hernia is in dynamic evoluation.Laparoscopic intra-peritoneal onlay mesh (IPOM) and open Sublay repair are still the best methods for the repair of abdominal wall hernia. The application of component separation technique has further widened the indications of IPOM and Sublay repair for the treatment of large abdominal wall hernia. Endoscopic Sublay technique theoretically combines the advantages of open Sublay repair and laparoscopic IPOM repair, but it has the disadvantages of iatrogenic destruction of the tendon septum and normal mechanical deconstruction, which requires strict specification of indications and further research.
ABSTRACT
Antecedentes: numerosas técnicas han sido descriptas para el tratamiento de defectos complejos de la pared abdominal. La técnica de separación de componentes con liberación del músculo transverso (TAR) permite la movilización de colgajos miofasciocutáneos y cierre de la línea media, con baja tasa de complicaciones. Objetivo: evaluar los resultados del tratamiento de eventraciones complejas con técnica TAR. Material y métodos: se incluyó una serie de pacientes en los que se realizó TAR entre marzo de 2013 y abril de 2017, con seguimiento mínimo de 6 meses. Se analizaron variables demográficas y clínicoquirúrgicas. Los resultados fueron expresados en medianas. Resultados: se realizaron 14 eventroplastias con técnica TAR. Diez (70%) correspondieron a hombres. La edad fue 60 (35-81) años y el IMC fue: 28,2 kg/m². El 70% tenía al menos dos cirugías previas. Se solicitó tomografía computarizada preoperatoria en todos los pacientes. El índice de Tanaka fue 24,5%. En 7 (50%) pacientes el riesgo quirúrgico fue ASA < III. El tamaño del defecto fue 480 (224-720) cm² y el de la malla 900 (500-1050) cm². El tiempo operatorio fue 248 (180-341) minutos, y la estadía hospitalaria, 3 (2-4) días. Dos pacientes tuvieron infección del sitio quirúrgico. El seguimiento posoperatorio fue de 20 (6-48) meses, y no se detectaron recidivas. Conclusión: la técnica TAR es un método seguro y fiable para la reparación de grandes defectos de la pared abdominal con baja morbimortalidad y recidiva, por lo que debería considerarse dentro del armamentario quirúrgico.

La hernia incisional suprapúbica constituye una enfermedad infrecuente, consecuencia generalmente de cirugías pélvicas en especial las que abordan el espacio retropúbico de Retzius. El objetivo dle trabajo es reportar los resultados del tratamiento quirúrgico de la hernia suprapúbica mediante el proceder tradicional de Rives-Stoppa asociado a la técnica de separación de componentes con bioprótesis de polipropileno como refuerzo. Se reportan tres pacientes con hernias suprapúbicas grandes. Estas se definieron como: todo defecto localizado en una distancia no mayor de 5 cm a la sínfisis del pubis con diámetro del anillo herniario superior a los 10 cm en su eje mayor medido transoperatoriamente. Fueron intervenidos quirúrgicamente tres pacientes, un hombre y dos mujeres. El primero con antecedentes de prostatectomía retropúbica y las dos últimas de cirugía ginecológica. En el primero, se complementó la operación de Rives-Stoppa con la técnica de separación anterior de componentes y refuerzo supra aponeurótico. Las dos últimas preferimos la separación posterior de componentes para evitar la disección anterior extensa. Las complicaciones más frecuentes fueron los seromas y hasta la fecha no se han reportado recurrencias. La reparación preperitoneal combinada con la técnica de separación de componentes anterior o posterior, constituyen alternativas válidas en la reparación de hernias incisionales complejas como son las hernias suprapúbicas. Esto permitió el cierre del defecto aponeurótico para cubrir y proteger la bioprótesis con la reconstrucción consiguiente de la línea alba(AU)
Suprapubic incisional hernia is a rare disease, generally the result of pelvic surgeries, especially those approaching the retropubic space of Retzius. To report the results of the surgical treatment of the suprapubic hernia by means of the traditional procedure of Rives-Stoppa associated to the component separation technique with polypropylene bioprosthesis as reinforcement. Three patients with large suprapubic hernias are reported. These were defined as: any defect located at a distance of no more than 5 cm from the symphysis pubis with diameter of the hernial ring over 10 cm at its major axis measured trans-operatively. Three patients, one man and two women were operated. The first, with a history of retropubic prostatectomy and the last two, with a history of gynecological surgery. In the first, the operation of Rives-Stoppa was complemented with the component separation technique and supra-aponeurotic reinforcement. For the last two, we preferred the posterior component separation in order to avoid extensive anterior dissection. The most frequent complications were seromas and, to date, no relapses have been reported. Preperitoneal repair combined with the technique of anterior or posterior component separation are valid alternatives in the repair of complex incisional hernias, such as suprapubic hernias. This allowed closure of the aponeurotic defect to cover and protect the bioprosthesis with the consequent reconstruction of the linea alba(AU)
