Abstract

Reestablishing anterior rectus fascial integrity remains a clinical challenge after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. The main concerns include herniation and bulging due to abdominal weakness. Mesh-assisted closure of the fascial defect has improved bulging and herniation rates but infection, extrusion, and encapsulation are serious concerns with mesh use. Biologic tissue matrices may overcome some of these mesh-related complications. The initial experience of using Strattice for fascial closure after TRAM flap procedure is described in this article. Strattice was in-lain and sutured between the anterior and posterior layers of the rectus fascia, at the rectus muscle donor site. The abdominal wall was closed with progressive tension sutures. Postoperative complications at the donor site were assessed. A total of 16 unilateral and 9 bilateral reconstructions were performed in 25 patients. Length of hospital stay was 2 to 3 days which is shorter than with mesh repair (typically 4-5 days). During a mean follow-up period of 14.0 months, complications occurred in 7 patients (28%): seroma formation (2), minor skin separation (2), superficial skin infection (2), and superficial wound dehiscence (1). Complications were not directly related to Strattice and all, except one (superficial skin infection), were resolved without surgical intervention. In all patients, routine abdominal functions were restored 4 months postoperatively. Strattice is a safe, alternative option to synthetic mesh for fascial repair following TRAM flap breast reconstruction. When used in conjunction with progressive tension suture closure of the abdominal wall, dynamic reconstruction of the abdominal wall with resumption of abdominal function is possible with Strattice.

摘要

在横行腹直肌肌皮瓣(TRAM)乳房重建术后,重建腹直肌筋膜的完整性仍是一项临床挑战。主要问题包括因腹部无力导致的疝形成和膨出。使用补片辅助闭合筋膜缺损可改善膨出和疝形成的发生率,但补片的使用会引发感染、补片挤出和包裹等严重问题。生物组织基质可能会克服一些与补片相关的并发症。本文介绍了在TRAM瓣手术后使用Strattice进行筋膜闭合的初步经验。将Strattice置于腹直肌筋膜的前后层之间,并在腹直肌供区进行缝合。用渐进性张力缝线关闭腹壁。评估供区的术后并发症。25例患者共进行了16例单侧和9例双侧重建。住院时间为2至3天,比使用补片修复(通常为4 - 5天)要短。在平均14.0个月的随访期内,7例患者(28%)出现并发症:血清肿形成(2例)、轻微皮肤分离(2例)、浅表皮肤感染(2例)和浅表伤口裂开(1例)。并发症与Strattice无直接关系,除1例(浅表皮肤感染)外,所有并发症均未经手术干预而得到解决。所有患者术后4个月腹部常规功能均恢复。对于TRAM瓣乳房重建术后的筋膜修复,Strattice是合成补片的一种安全替代选择。当与腹壁的渐进性张力缝线闭合联合使用时,Strattice可实现腹壁的动态重建并恢复腹部功能。
