Abstract

Introduction: Preoperative BTA assists with fascial closure during abdominal wall reconstruction. Its efficacy in subxiphoid (M1) hernias has been questioned with high rates of component separation techniques (CST) despite BTA. To assess the role of BTA in these hernias, we compared fascial closure and recurrence rates in patients with M1 hernias requiring CST with or without preoperative BTA.

Methods: A prospectively maintained database at a tertiary hernia center was reviewed for M1 hernias who underwent CST, and grouped based on use of preoperative BTA. Standard univariate analysis was performed.

Results: Of 67 patients, 30 (44.8%) received preoperative BTA. BTA versus non-BTA groups had similar mean ages (56.0 ± 14.1vs.61.5 ± 11.8 years, p = 0.087), ASA score (p = 0.345), rate of diabetes (p = 0.421), and very large defect size (499.2 ± 185.5vs.416.1 ± 238.6 cm2,p = 0.144). In the BTA group, BMI was lower (28.9 ± 5.1vs.32.7 ± 7.2 kg/m2,p = 0.018), with fewer current smokers (0%vs.10.8%,p = 0.006), and more contaminated (20.0%vs.5.4%) and dirty cases (33.3%vs.13.5%) (p = 0.008). External oblique release was performed in 24 (80.0%) BTA patients versus 23 (62.2%) non-BTA (p = 0.179), posterior CST in 6 (20.0%) versus 14 (37.8%) (p = 0.133). Rates of bilateral CST (90.0%vs.94.6% p = 0.394), fascial closure (90.0%vs.94.6%,p = 0.650), overall wound complications (33.3%vs.43.2%,p = 0.458), and recurrence (6.7%vs.2.7%,p = 0.583) were similar with average follow up of 12.7 ± 18.8 versus 24.1 ± 28.2 months (p = 0.062).

Conclusion: Repair of very large M1 hernias requires high rates of CST despite preoperative BTA injection. When CST is needed, BTA as a preoperative adjunct does not appear to offer benefit in terms of fascial closure rates, frequency of bilateral CST, or risk of recurrence.

期刊介绍: Hernia was founded in 1997 by Jean P. Chevrel with the purpose of promoting clinical studies and basic research as they apply to groin hernias and the abdominal wall . Since that time, a true revolution in the field of hernia studies has transformed the field from a ”simple” disease to one that is very specialized. While the majority of surgeries for primary inguinal and abdominal wall hernia are performed in hospitals worldwide, complex situations such as multi recurrences, complications, abdominal wall reconstructions and others are being studied and treated in specialist centers. As a result, major institutions and societies are creating specific parameters and criteria to better address the complexities of hernia surgery. Hernia is a journal written by surgeons who have made abdominal wall surgery their specific field of interest, but we will consider publishing content from any surgeon who wishes to improve the science of this field. The Journal aims to ensure that hernia surgery is safer and easier for surgeons as well as patients, and provides a forum to all surgeons in the exchange of new ideas, results, and important research that is the basis of professional activity.
