Proposal for a uniform protocol and checklist for cadaveric courses for surgeons with special interest in open abdominal wall reconstruction.

Purpose: Over the last decade, there has been a rapid rise in the development and refinement of abdominal wall repair (AWR) techniques. Numerous cadaveric AWR training courses have been set up with the goal of helping practicing surgeons learn and incorporate them into their surgical repertoire. Some maybe excellent but their quality and consistency are unknown.

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.

Outcomes of liver transplantation with thoracoabdominal normothermic regional perfusion: a matched-controlled initial experience in Spain.

Thoracoabdominal (TA) normothermic regional perfusion (NRP) should allow the safe recovery of heart and liver grafts simultaneously in the context of controlled donation after circulatory death (cDCD). We present the initial results of cDCD liver transplantation with simultaneous liver and heart procurement in Spain until October 2021. Outcomes were compared with a matched cohort of cDCD with abdominal NRP (A-NRP) from participating institutions.

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.

Short-term outcomes of a multicentre prospective study using a "visible" polyvinylidene fluoride onlay mesh for the prevention of midline incisional hernia.

Introduction: Prophylactic meshes in high-risk patients prevent incisional hernias, although there are still some concerns about the best layer to place them in, the type of fixation, the mesh material, the significance of the level of contamination, and surgical complications. We aimed to provide answers to these questions and information about how the implanted material behaves based on its visibility under magnetic resonance imaging (MRI).

Method: This is a prospective multicentre observational cohort study.

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.

[Incisional hernia: open abdominal wall reconstruction. Current state of the technique and results].

The treatment of complex midline hernias remains a particular challenge. The currently refined knowledge of the anatomy in the cadaver laboratory and advancing clinical experience have changed our present approach. The aim of this review is to present a description of the updated surgical procedures and outcomes.

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.

Abdominal normothermic regional perfusion in controlled donation after circulatory determination of death liver transplantation: Outcomes and risk factors for graft loss.

Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]).

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.

Incidence and risk factors of delayed development for stoma site incisional hernia after ileostomy closure in patients undergoing colorectal surgery with temporary ileostomy.

Background: Stoma site incisional hernias after ileostomy closure are complex hernias that can be associated with abdominal pain, discomfort, and a diminished quality of life. The aim of this study was to determine the incidence of incisional hernia (IH) following temporary ileostomy reversal in patients undergoing colorectal surgery, and the risk factors associated with its development.

Methods: This was a prospective, single-centre, cohort study of patients undergoing ileostomy reversal between January 2010 and December 2016.

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

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.

Hepatic Epithelioid Hemangioendothelioma as a Rare Indication for Liver Transplantation.

Background: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare neoplasm of vascular origin, with nonspecific presentation and unpredictable clinical course. Several therapeutic options are available according to the literature, including chemotherapy and radiotherapy, liver resection (LR), and liver transplantation (LT).

Methods: We present 2 cases of patients with HEHE treated with liver transplantation in our center, a 30-year-old man and a 42-year-old woman, diagnosed with several lesions involving both liver lobes.

Normothermic regional perfusion vs. super-rapid recovery in controlled donation after circulatory death liver transplantation.

Background & Aims: Although there is increasing interest in its use, definitive evidence demonstrating a benefit for postmortem normothermic regional perfusion (NRP) in controlled donation after circulatory death (cDCD) liver transplantation is lacking. The aim of this study was to compare results of cDCD liver transplants performed with postmortem NRP vs. super-rapid recovery (SRR), the current standard for cDCD.

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.
