Complex Abdominal Wall Hernia Repair in Contaminated Surgical Fields: Factors Affecting the Choice of Prosthesis.

To compare patients with complex abdominal wall hernias undergoing surgical repair using synthetic nonabsorbable or biologic meshes in contaminated fields. Retrospective review of 62 patients with complex abdominal wall hernia with surgical repair in an elective setting and in the context of a clean-contaminated or contaminated fields (January 2009-April 2015). Two groups according to the prosthesis (synthetic nonabsorbable, n = 48 or biologic, n = 14). Mean follow-up was 24.6 (15.8) months. Clean-contaminated wounds were significantly more frequent in the synthetic group. Contaminated wounds were significantly more frequent in the biologic group. Enterocutaneous fistula, recurrent hernia, and removal of chronic infected mesh were significantly more frequently in the biologic group. Differences in postoperative complications and surgical site infections were not found. Recurrence was higher in the biologic group (35.7% vs 8.3%, P = 0.03). In the elective repair of complex hernia, the level of contamination, a recurrent hernia, an enterocutaneous fistula or removal of chronic infected mesh were the factors affecting the choice of prosthesis. In the clean-contaminated setting, the use of a synthetic nonabsorbable mesh versus a biologic mesh did not increase the rate of postoperative infections. Recurrences are significantly higher with biologic meshes.

Cierre de la pared abdominal después del cierre de un estoma temporal / Abdominal wall closure after a stomal reversal procedure

Revertir un estoma temporal implica 2 procedimientos quirúrgicos diferentes: la reconstrucción del tránsito intestinal y el cierre de la pared abdominal en el sitio del estoma. Este último presenta diferentes aspectos que deben ser analizados: a) la infección del sitio quirúrgico (ISQ), b) el manejo de una hernia coincidente en el sitio del estoma en el momento de su cierre, c) la prevención del desarrollo de una hernia incisional posterior, d) el cierre del estoma en el caso de que se realice la reconstrucción del tránsito por vía laparoscópica, o e) el cierre de la piel del sitio del estoma. El objetivo de este trabajo es analizar estos aspectos en relación con la reconstrucción de la pared abdominal por la que emerge un estoma temporal cuando se procede al cierre de este

The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure

Abdominal wall closure after a stomal reversal procedure.

The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site.

Implantes biológicos en la cirugía de las hernias de la pared abdominal / Biological implants in abdominal wall hernia surgery

Los materiales sintéticos permanentes son de elección en la actualidad para la reparación de las hernias de la pared abdominal. Sin embargo, no son ideales y se describen complicaciones relacionadas con ellos a corto y largo plazo. Fruto de la investigación y desarrollo de nuevos materiales han surgido los implantes biológicos derivados de la matriz extracelular (IBMEC). En los últimos años han aparecido varios tipos de IBMEC, cada uno con características propias de manufacturación y diferentes a los demás. En este trabajo se analiza el panorama actual de los IBMEC xenogénicos disponibles en nuestro medio, el laberinto que suponen, las incógnitas que plantean a largo plazo y la experiencia clínica disponible en las hernias incisionales e inguinales (AU)

Permanent synthetic materials are currently of choice for abdominal wall hernia repair. However, they are not ideal as short- and long-term complications with these have been reported. Extracellular matrix-derived biological implants (EMDBI) have emerged as a result of research and development into new materials. Several types of EMDBI have appeared in the last few years, each with its own manufacture characteristics and different from the rest. The current panorama of the xenogeneic EMDBI available in Spain is analysed, their complications, the unknown factors arising in the long-term, and the clinical experience available on incisional and inguinal hernias (AU)
