How I Do It: Madrid posterior component separation in 10 steps, with special consideration of its anatomy.

Purpose: The Madrid Posterior Component Separation technique (Madrid PCS) is an approach for abdominal wall reconstruction that leverages anatomical landmarks to optimize outcomes. This manuscript describes ten essential steps for performing the Madrid PCS, focusing on technique, safety, and efficiency.

Methods: A comprehensive step-by-step approach is outlined, beginning with the initial incision and adhesiolysis, progressing through retromuscular dissection, and concluding with lateral release and subxiphoid dissection.

Sequential Fasciotomies for Managing Abdominal Compartment Syndrome: Porcine Experimental Study.

Introduction: Abdominal compartment syndrome (ACS) poses a significant clinical challenge, with high morbidity and mortality rates. Conventional treatment via decompressive laparotomy with open abdomen and temporary closure presents significant drawbacks. This experimental study evaluates the efficacy of open minimally invasive sequential fasciotomy in managing simulated ACS in a porcine model.

Role of sarcopenia in complex abdominal wall surgery: does it increase postoperative complications and mortality?

Background: Sarcopenia is defined as the loss of skeletal muscle mass and is associated with an increased risk or morbidity and mortality in complex surgical patient populations. Its role in complex abdominal wall surgery (AWS) is yet to be determined. The aim of this study is to establish if sarcopenia has an impact on postoperative complications, mortality and hernia recurrence.

Comprehensive retrospective analysis of the European hernia Society quality of life in patients undergoing abdominal wall reconstruction.

Introduction: This study aimed to analyze the European Hernia Society Quality of Life (EHS-QoL) in abdominal wall reconstruction by comparing preoperative scores with those at 1 and 2 postoperative years.

Methods: Data from 105 patients with complex incisional hernias were collected preoperatively and at 1 and 2 years postoperatively. Statistical analyses included three ART ANOVA models to compare scores among the three time points and within each time point's items.

The Madrid Posterior Component Separation: An Anatomical Approach for Effective Reconstruction of Complex Midline Hernias.

Introduction: In recent years, Posterior Component Separation (PCS) with the Madrid modification (Madrid PCS) has emerged as a surgical technique. This modification is believed to enhance the dissection of anatomical structures, offering several advantages. The study aims to present a detailed description of this surgical technique and to analyse the outcomes in a large cohort of patients.

Incisions in Hepatobiliopancreatic Surgery: Surgical Anatomy and its Influence to Open and Close the Abdomen.

Incisions performed for hepato-pancreatic-biliary (HPB) surgery are diverse, and can be a challenge both to perform correctly as well as to be properly closed. The anatomy of the region overlaps muscular layers and has a rich vascular and nervous supply. These structures are fundamental for the correct functionality of the abdominal wall.

Recurrence after retromuscular repair or posterior components separation: How to address them. A retrospective multicentre cohort study.

Abdominal wall hernias are common entities that represent important issues. Retromuscular repair and component separation for complex abdominal wall defects are considered useful treatments according to both short and long-term outcomes. However, failure of surgical techniques may occur.

Reverse TAR may be added when necessary in open preperitoneal repair of lateral incisional hernias: a retrospective multicentric cohort study.

Background: The best approach for lateral incisional hernia is not known. Posterior component separation (reverse TAR) offers the possibility of using the retromuscular space for medial extension of the challenging preperitoneal plane. The aim of our multicenter study was to compare the operative and patient-reported outcomes measures (PROMs) using two open surgical techniques from the lateral approach: a totally preperitoneal vs a reverse TAR.

High recurrence rate after posterior component separation and keyhole mesh reconstruction for complex parastomal hernia: A case series study.

Aim: This study aimed to describe the results of complex parastomal hernia repair after posterior component separation and keyhole reconstruction.

Method: We conducted a retrospective review of a prospectively sustained database in one single complex abdominal wall referral centre. We analysed the data of patients who underwent the posterior component separation technique using modified transversus abdominis release for complex parastomal hernia and retromuscular keyhole mesh repair from February 2014 to January 2017.

Stepwise transversus abdominis muscle release for the treatment of complex bilateral subcostal incisional hernias.

Background: Management of subcostal incisional hernias is particularly complicated due to their proximity to the costochondral limits in addition to the lack of aponeurosis on the lateral side of the abdomen. We present our results of posterior component separation through the same previous incision as a safe and reproducible technique for these complex cases.

Methods: We present a multicenter and prospective cohort of patients diagnosed with bilateral subcostal incisional hernias on either clinical examination or imaging based on computed tomography from 2014 to 2020.

Second Look After Retromuscular Repair With the Combination of Absorbable and Permanent Meshes.

The aim of this study is to describe the macroscopic features and histologic details observed after retromuscular abdominal wall reconstruction with the combination of an absorbable mesh and a permanent mesh. We have considered all patients that underwent abdominal wall reconstruction (AWR) with the combination of two meshes that required to be reoperated for any reason. Data was extracted from a prospective multicenter study from 2012 to 2019.

Outcomes of abdominal wall reconstruction in patients with the combination of complex midline and lateral incisional hernias.

Background: The best treatment for the combined defects of midline and lateral incisional hernia is not known. The aim of our multicenter study was to evaluate the operative and patient-reported outcomes using a modified posterior component separation in patients who present with the combination of midline and lateral incisional hernia.

Methods: We identified patients from a prospective, multicenter database who underwent operative repairs of a midline and lateral incisional hernia at 4 centers with minimum 2-year follow-up.

Abdominal Wall Reconstruction Utilizing the Combination of Absorbable and Permanent Mesh in a Retromuscular Position: A Multicenter Prospective Study.

Background: Optimal mesh reinforcement for abdominal wall reconstruction (AWR) in complex hernias remains questionable. Use of biologic, absorbable and synthetic meshes has been described. The idea of using an absorbable mesh (AM) under a permanent mesh (PM) in a retromuscular position may help in these challenging situations.

How we do it: down to up posterior components separation.

Background: Posterior component separation with transversus abdominis release technique is increasingly being used for abdominal wall reconstruction in complex abdominal wall repair. The main purpose of this study is to present a modification of the surgical technique originally described that facilitates the surgical procedure and offers additional advantages.

Methods: Based on the knowledge of the anatomy of the retromuscular space and the preperitoneal aerolar tissue distribution, we start the incision on the posterior rectus sheath from the arcuate line in a down to up direction.

Prophylactic mesh can be used safely in the prevention of incisional hernia after bilateral subcostal laparotomies.

Background: The use of prophylactic mesh to prevent incisional hernia is becoming increasingly common in midline laparotomies and colostomies. The incidence of incisional hernia after subcostal laparotomies is lower than after midline incisions. Nevertheless, the treatment of subcostal incisional hernia is considered to be more complex.
