Abstract

Background: Anterior component separation (ACS), or Ramirez component separation technique, is an established technique still used by surgeons to repair a ventral hernia. Compared with other ventral hernia repair techniques, recent studies about ACS show more postoperative complications like wound breakdown, wound infection, hematoma, skin necrosis, seroma, and recurrence. Our study aims to compare the ACS technique with the preservation perforator technique and verify if the perforator preservation technique can decrease postoperative complications.

Materials and methods: Cochrane Central, Embase, and PubMed were systematically searched for studies comparing the perforator-sparing ACS ventral hernia repair and the standard technique. Outcomes assessed were wound breakdown, skin necrosis, wound infection, seroma, hematoma, reoperation, and recurrence at least 3 months postoperatively. Statistical analysis was performed with R Studio.

Results: 94 studies were screened, and 11 studies were selected for full-text reading. Seven studies were selected, comprising 761 patients, of which 309 (40.6%) underwent the perforator-sparing ACS technique. We found lower wound breakdown rates for the preservation technique (RR 0.45; 95% CI 0.32; 0.63; p < 0.01). Also, the perforator-sparing technique presented lower reoperation rates (RR 0.59; 95% CI 0.35; 0.72; p < 0.01). No differences were found in skin necrosis (RR 0.22; 95% CI 0.03; 1.63; p = 0.14), wound infection (RR 0.69; 95% CI 0.25; 1.90; p = 0.47), seroma (RR 0.29; 95% CI 0.07; 1.26; p = 0.1), hematoma (RR 0.73; 95% CI 0.11; 5.06; p = 0.75), or recurrence (RR 0.81; 95% CI 0.37; 1.74; p = 0.59) rates.

Conclusion: Our comprehensive systematic review with meta-analysis compared the perforator-sparing ACS with the standard technique and found lower wound breakdown and reoperation rates for the perforator-sparing technique. No differences were found in the other outcomes analyzed.

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.
