RESUMO

Abdominal wall reconstruction aims at restoring the anatomical, functional and aesthetic integrity of this region, while providing protection of abdominal viscera and prevent herniation. There are various techniques used for abdominal wall reconstruction. We present a difficult case of abdominal wall reconstruction performed with a pedicled antero-lateral thigh (ALT] flap with good postoperative results.

RESUMO

Background: Ever since the description of the first microvascular anastomosis, numerous alternative methods have been described to the classical approach. Tissue adhesive has shown promising result in previous studies and can be a fast and efficient alternative which still requires more studies to allow its clinical implementation. Methods: A randomized comparative experimental study was conducted on rats' femoral arteries and an end-to-end anastomosis was performed in order to compare 2 anastomosis techniques. In one group, a simple interrupted suture was utilized, whereas in the second group a combination between fewer sutures and tissue adhesive was used. The anastomotic time, total operative time, blood flow velocity before, immediately after and 48 hours after the procedure, as well as an independent grading of the anastomosis immediately after the procedure were performed. Magnetic resonance imaging (MRI) was performed in order to assess the degree of stenosis. After euthanasia, histology and scanning electron microscopy (SEM) were performed on the vessels in order to assess possible complications. Results: A total of 24 anastomoses were performed, of which 12 with a classic technique and 12 with an adhesive technique. All the anastomoses were patent with a significant reduction of anastomotic and total operative time. The grading of the anastomoses showed better results in the classic suture group. The blood flow velocities were not statistically significant between the 2 groups. On MRI there was one stenotic anastomosis, whereas histology and SEM showed more complications on the adhesive group. Conclusion: Anastomotic times were significantly lower with a non-significant trend toward more thrombotic complications in the adhesive group. Further improvement of the glue properties and refinement of the technique will likely make it a viable alternative to interrupted suturing in the future.


Historique: Depuis que la première anastomose microvasculaire a été décrite, de nombreuses méthodes ont été utilisées en plus de la méthode classique. L'adhésif tissulaire a donné des résultats prometteurs dans des études antérieures et peut représenter une solution rapide et efficace qui devra faire l'objet de plus d'études avant d'être adoptée en clinique. Méthodologie: Les chercheurs ont mené une étude expérimentale aléatoire et comparative sur des artères fémorales de rat. Ils ont effectué une anastomose de bout en bout pour comparer deux techniques d'anastomose. Dans un groupe, une seule suture interrompue a été utilisée, et dans le second, une combinaison d'un moins grand nombre de sutures et d'adhésif tissulaire a été privilégiée. La durée de l'anastomose, la durée totale de l'intervention, la vélocité du débit sanguin avant, immédiatement après et 48 heures après l'intervention, de même que le classement indépendant de l'anastomose immédiatement après l'intervention. L'imagerie par résonance magnétique a permis d'évaluer le degré de sténose. Après l'euthanasie, les chercheurs ont effectué l'histologie et la microscopie électronique sur les vaisseaux pour évaluer les complications possibles. Résultats: Au total, 24 anastomoses ont été exécutées, soit 12 avec la technique classique et 12 avec la technique d'adhésion. Toutes les anastomoses étaient perméables et s'associaient à une réduction importante de la durée de l'anastomose et de l'opération totale. Le classement de l'anastomose a révélé de meilleurs résultats dans le groupe de suture classique. La vélocité du débit sanguin n'était pas statistiquement significative entre les deux groupes. On a constaté une anastomose sténosée à l'imagerie par résonance magnétique, tandis que l'histologie et la microscopie électronique ont révélé plus de complications dans le groupe d'adhésion. Conclusion: La durée de l'anastomose était beaucoup plus courte et présentait une tendance non significative vers un plus grand nombre de complications thrombotiques dans le groupe d'adhésion. Des améliorations des propriétés de la coller et le raffinement des techniques en feront probablement une solution viable pour remplacer les sutures.

RESUMO

Plastic surgeons strive to choose better techniques to reconstruct the defects of the limbs, minimising the wound healing problems, improving the aesthetic and functional outcome with less complications. This study refers to the use of keystone perforator island flap (KPIF) in limbs' reconstruction, their harvesting technique to minimise donor-site morbidity, maximise the functional and cosmetic outcome, and will point on the most important indications and advantages. Between January 2014 and June 2020, a number of 28 cases were treated in our department, with simple or complex defects of the limbs. The database included patients' demographics, comorbidities, aetiology, characteristics of the flap, surgical factors, follow-up period and flap outcomes. We performed 28 KPIFs, 14 of type I, 12 of type IIA, 1 of type III, and 1 of type IV, with an average size of 69 cm2 (ranged from 1.25 cm2 to 318 cm2 ). Trauma was the major cause of the defects. One flap exhibited approximately 4% partial superficial necrosis. All donor sites healed without any adverse events. All patients were satisfied with the functional and aesthetic results. The KPIFs provide a simple and effective method of wound closure by using tissues of similar texture, thickness and colour. Preserving the main artery and the underlying muscle, this flap reduces the donor site morbidity. The use of KPIFs seems to be one of the most suitable choices whenever possible.
