RESUMO
PURPOSE: To evaluate the incidence of incisional hernia in patients undergoing direct access to the abdominal cavity in urological surgery. METHODS: We conducted a systematic review in Pubmed, Embase, and Cochrane Central from 1980 to the present according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Eighty-four studies were selected for inclusion in this analysis, and meta-analysis and meta-regression were performed. RESULTS: The total incidence in the 84 studies was 4.8% (95% CI 3.7% - 6.2%) I2 93.84%. Depending on the type of incision, it was higher in the open medial approach: 7.1% (95% CI 4.3%-11.8%) I2 92.45% and lower in laparoscopic surgery: 1.9% (95% CI 1%-3.4%) I2 71, 85% According to access, it was lower in retroperitoneal: 0.9% (95% CI 0.2%-4.8%) I2 76.96% and off-midline: 4.7% (95% CI 3.5%-6.4%) I2 91.59%. Regarding the location of the hernia, parastomal hernias were more frequent: 15.1% (95% CI 9.6% - 23%) I2 77.39%. Meta-regression shows a significant effect in reducing the proportion of hernias in open lateral, laparoscopic and hand-assisted compared to medial open access. CONCLUSION: The present review finds the access through the midline and stomas as the ones with the highest incidence of incisional hernia. The use of the lateral approach or minimally invasive techniques is preferable. More prospective studies are warranted to obtain the real incidence of incisional hernias and evaluate the role of better techniques to close the abdomen.

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. Preliminary results from the first 3 months are presented. We included general surgical patients who had at least two risk factors for developing an incisional hernia. Multivariate logistic regression was used. A polyvinylidene fluoride (PVDF) mesh loaded with iron particles was used in an onlay position. MRIs were performed 6 weeks after treatment. RESULTS: Between July 2016 and June 2022, 185 patients were enrolled in the study. Surgery was emergent in 30.3% of cases, contaminated in 10.7% and dirty in 11.8%. A total of 5.6% of cases had postoperative wound infections, with the requirement of stoma being the only significant risk factor (OR = 7.59, p = 0.03). The formation of a seroma at 6 weeks detected by MRI, was associated with body mass index (OR = 1.13, p = 0.02). CONCLUSIONS: The prophylactic use of onlay PVDF mesh in midline laparotomies in high-risk patients was safe and effective in the short term, regardless of the type of surgery or the level of contamination. MRI allowed us to detect asymptomatic seromas during the early process of integration. STUDY REGISTRATION: This protocol was registered at ClinicalTrials.gov (NCT03105895).

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. METHODS: A retrospective cohort study was performed since 2012 to 2020. Patients with lateral incisional hernia treated through a lateral approach were identified from a prospectively maintained multicenter database. Reverse TAR was added when the preperitoneal plane could not be safely dissected. The results obtained using these two lateral approaches were compared, including short- and long-term complications, as well as PROMs, using the specific tool EuraHSQoL. RESULTS: A total of 61 patients were identified. Reverse TAR was performed in 33 patients and lateral retromuscular preperitoneal approach in 28 patients. Both groups were comparable in terms of sociodemographic and comorbidities variables. Surgical site occurrences occurred in 13 cases (21.3%), with 8 patients (13.1%) requiring procedural intervention. During a median follow-up of 34 months, no incisional hernia recurrence was registered. There was a case (1.6%) of symptomatic bulging that required reoperation. Also 12 patients (19.7%) presented an asymptomatic bulging. No statistically significant difference was identified in the complications and PROMs between the two procedures. CONCLUSION: The open lateral retromuscular reconstruction using very large meshes that reach the midline has excellent long-term results with acceptable postoperative complications, including PROMs. A reverse TAR may be added, when necessary, without increasing complications and obtaining similar long-term results.

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. Demographic data, hernia characteristics, operative details and outcomes were analysed. The primary outcome measured was the recurrence rate during the follow-up. RESULTS: Twenty patients were included in this study. Among the patients who underwent surgery for parastomal hernia, 17 patients had a colostomy (85%) and three patients had a ureteroileostomy after the Bricker procedure (15%). The mean body mass index was 33.2 kg/m2 (range 25-47). Twelve patients had an expected associated risk according to the Carolinas equation for determining associated risk classification of >60%. Sixty per cent of our patients had contaminated or dirty/infected wounds. The overall complication rate was 60%. Surgical site infection was observed in 25% of the cases. The mortality rate in our study group was 5% (n = 1). We found clinical or radiological evidence of parastomal hernia recurrence in nine out of 20 (45%) patients during follow-up. No hernia recurrence was detected in the concomitant incisional hernias. CONCLUSIONS: Although posterior component separation in the form of modified transversus abdominis muscle release allows abdominal wall reconstruction, keyhole mesh configuration at the stoma site does not offer satisfactory results in terms of long-term recurrence rate at the parastomal defect.

BACKGROUND: Up to 25% of patients with acute pancreatitis develop severe complications and are classified as severe pancreatitis with a high death rate. To improve outcomes, patients may require interventional measures including surgical procedures. Multidisciplinary approach and best practice guidelines are important to decrease mortality. METHODS: We have conducted a retrospective analysis from a prospectively maintained database in a low-volume hospital. A total of 1075 patients were attended for acute pancreatitis over a ten-year period. We have analysed 44 patients meeting the criteria for severe acute pancreatitis and for intensive care unit (ICU) admittance. Demographics and clinical data were analysed. Patients were treated according to international guidelines and a multidisciplinary flowchart for acute pancreatitis and a step-up approach for pancreatic necrosis. RESULTS: Forty-four patients were admitted to the ICU due to severe acute pancreatitis. Twenty-five patients needed percutaneous drainage of peri-pancreatic or abdominal fluid collections or cholecystitis. Eight patients underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis and biliary sepsis or pancreatic leakage, and one patient received endoscopic trans-gastric endoscopic prosthesis for pancreatic necrosis. Sixteen patients underwent surgery: six patients for septic abdomen, four patients for pancreatic necrosis and two patients due to abdominal compartment syndrome. Four patients had a combination of surgical procedures for pancreatic necrosis and for abdominal compartment syndrome. Overall mortality was 9.1%. CONCLUSION: Severe acute pancreatitis represents a complex pathology that requires a multidisciplinary approach. Establishing best practice treatments and evidence-based guidelines for severe acute pancreatitis may improve outcomes in low-volume hospitals.

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. METHODS: Between 2011 and 2016, consecutive patients undergoing open AWR utilizing an AM as posterior layer reinforcement and configuration of a large PM were identified in a multicenter prospectively maintained database in four hospitals. Main outcomes included demographics, ventral hernia classifications, perioperative data, complications and recurrences. RESULTS: A total of 169 complex incisional hernias were analyzed. Mean age was 60.9, with mean body mass index 30.7 (range: 20-46). Location of incisional hernias (IH) was: 80 midline, 59 lateral and 30 midline and lateral. 78% were grade I and II in Ventral Hernia Working Group classification. 52% of patients were discharged with no complication. There were 19% seromas, 13% hematomas, 12% surgical-site infection and 10% skin dehiscence. Only partial mesh removal was necessary in one patient. After a mean follow-up of 26 months (range 15-59), there were five (3.2%) recurrences. Reoperations on patients showed a band of fibrosis separating the peritoneum from the PM. CONCLUSION: The combination of AM with very large PM in the same retromuscular position in AWR seems to be safe. The efficacy with recurrence rates below 4% in complex midline and lateral IH may be explained by the use of larger PMs that are extended and configured with the support of AMs. Reoperations on patients have confirmed the previous experimental reports on the use of the AM.

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. The posterior rectus sheath is incised 0,5-1 cm medial to the linea semilunaris and cut longitudinally as far as the fibers of transversus abdominis muscle that are divided in the superior part of the abdomen. It is also possible to avoid cutting the fibers of this muscle if we incise the posterior rectus sheath in an oblique direction to the midline from the umbilical area. Since 2012 to 2016, 69 consecutive patients with down to up TAR have been prospectively followed. Main outcome measures included demographics, perioperative details, wound complications, and recurrences. RESULTS: Between 2012 and 2016, we have operated 69 patients with down to up TAR technique. Mean operative time was 251 (range 65-566) minutes. Mean hospital stay was 9,8 (2-98) days. 10 patients presented surgical site events (14,5%): 6 patients had superficial site infection, 3 deep and 1 organ space. During follow-up, 3 patients (4,3%) presented incisional hernia recurrence. CONCLUSIONS: This novel modification allows a simpler dissection of the preperitoneal retromuscular space and makes the TAR technique easier to perform. It also enables to incise only the insertion of the transversalis fascia cranially.

OBJECTIVE: To reduce the incidence of incisional hernia (IH) in colorectal surgery by implanting a mesh on the overlay position. BACKGROUND: The incidence of IH in colorectal surgery may be as high as 40%. IH causes severe health and cosmetic problems, and its repair increases health care costs. MATERIAL AND METHODS: Randomized, controlled, prospective trial. Patients undergoing any colorectal procedure (both elective and emergency) through a midline laparotomy were divided into 2 groups. The abdomen was closed with an identical technique in both groups, except for the implantation of an overlay large-pore polypropylene mesh in the study group. Patients were followed up clinically and radiologically for 24 months. RESULTS: A total of 107 patients were included: 53 in the study group and 54 in the control group. Both groups were homogeneous, except for a higher incidence of diabetes in the mesh group. There were 20 emergency procedures in the study group and 17 in the control group. There were no statistical differences in surgical site infections, seromas, or mortality between the groups (33.3%, 13.8%, and 3.7% in the control group and 18.9%, 13.2%, and 3.8% in the study group). No mesh rejection was reported. The incidence of IH was 17 of 54 (31.5%) in the control group and 6 of 53 (11.3%) in the study group (P = 0.011). CONCLUSIONS: The incidence of IH is high in patients undergoing elective or emergency surgery for colorectal diseases. The addition of a prophylactic large-pore polypropylene mesh on the overlay position decreases the incidence of IH without adding morbidity.

The new published guidelines of compartment syndrome are supposed to be a helpful tool in order to make decisions in patients with abdominal hypertension. From a surgical perspective of view, an important effort has been made in order to reach consensus in different phases in which there is no clear answer in evidence-based medicine. It is mandatory the use of a universal classification of open abdomen and there are three main concepts that must be observed: make a decompressive laparotomy when conservative measures have failed, attempt to closure the abdomen as soon as possible and the use of negative-pressure treatments that facilitates the management of an open abdomen. Although most of recommendations that have been delivered are not high grades, the present guide is an important assistant for the management of intra-abdominal hypertension and several lines of investigation are opened in order to answer the doubts that have been addressed.

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. RESULTS: The EHS score significantly decreased from preoperative (Mdn â= â57) to 1 year (Mdn â= â10.5) and 2 years postoperative (Mdn â= â8). The most significant changes occurred between preoperative and 1-year measurements, particularly in pain levels during activities and limitations in heavy labor and activities outside the home. CONCLUSION: Patients' quality of life notably improved at 1 year post-surgery, with some reaching near-maximum levels, and this improvement was generally sustained or increased at 2 years post-surgery.
RESUMO
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. Materials and Methods: This study included all patients who underwent the repair of midline incisional hernias, with or without other abdominal wall defects. Data from patients at three different centres specialising in abdominal wall reconstruction was analysed. All patients underwent the Madrid PCS, and several variables, such as demographics, perioperative details, postoperative complications, and recurrences, were assessed. Results: Between January 2015 and June 2023, a total of 223 patients underwent the Madrid PCS. The mean age was 63.4 years, with a mean BMI of 33.3 kg/m2 (range 23-40). According to the EHS classification, 139 patients had a midline incisional hernia, and 84 had a midline incisional hernia with a concomitant lateral incisional hernia. According to the Ventral Hernia Working Group (VHWG) classification, 177 (79.4%) patients had grade 2 and 3 hernias. In total, 201 patients (90.1%) were ASA II and III. The Carolinas Equation for Determining Associated Risks (CeDAR) was calculated preoperatively, resulting in 150 (67.3%) patients with a score between 30% and 60%. A total of 105 patients (48.4%) had previously undergone abdominal wall repair surgery. There were 93 (41.7%) surgical site occurrences (SSO), 36 (16.1%) surgical site infections (SSI), including 23 (10.3%) superficial and 7 (3.1%) deep infections, and 6 (2.7%) organ/space infections. Four (1.9%) recurrences were assessed by CT scan with an average follow-up of 23.9 months (range 6-74). Conclusion: The Madrid PCS appears to be safe and effective, yielding excellent long-term results despite the complexity of abdominal wall defects. A profound understanding of the anatomy is crucial for optimal outcomes. The Madrid modification contributes to facilitating a complete retromuscular preperitoneal repair without incision of the transversus abdominis. The extensive abdominal wall retromuscular dissection obtained enables the placement of very large meshes with minimal fixation.
RESUMO
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. We favor the retromuscular or preperitoneal layer for mesh implantation, including the Rives-Stoppa procedure (sublay mesh) and posterior component separation with the Madrid modification. We operated on 334 complex midline incisional hernias: 6.3% retromuscular preperitoneal, 15% after Rives-Stoppa, 2.4% anterior component separation and 76% posterior component separation. A bridging procedure was used in 31%. A complication occurred in 35.3%, most of which were wound healing disorders (SSO). The average length of hospital stay was 7.2 days. We recorded a very low incidence of long-term complications: 3.3% recurrence, 0.9% chronic pain (daily use of pain medication), 6% bulging, 1.8% chronic seroma and 2.6% chronic mesh infection. Despite the associated morbidity, retromuscular/preperitoneal treatment offers excellent long-term results.

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. The aim of this study is to analyze results of surgical treatment for hernia recurrence after prior retromuscular or posterior components separation. We have retrospectively reviewed patient charts from a prospectively maintained database. This study was conducted in three different hospitals of the Madrid region with surgical units dedicated to abdominal wall reconstruction. We have included in the database 520 patients between December 2014 and December 2021. Fifty-one patients complied with the criteria to be included in this study. We should consider offering surgical treatment for hernia recurrence after retromuscular repair or posterior components separation. However, the results might be associated to increased peri-operative complications.

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. When performing certain types of incisions, damage to the muscular or neurovascular component of the abdominal wall, as well as an inadequate closure technique may influence in the development of long-term complications as incisional hernias (IH) or bulging. Considering that both may impair quality of life and that are complex to repair, prevention becomes essential during these procedures. With the currently available evidence, there is no clear recommendation on which is the better incision or what is the best method of closure. Despite the lack of sufficient data, the following review aims to correlate the anatomical knowledge learned from posterior component separation with the incisions performed in hepato-pancreatic-biliary (HPB) surgery and their consequences on incisional hernia formation. Overall, there is data that suggests some key points to perform these incisions: avoid vertical components and very lateral extensions, subcostal should be incised at least 2 cm from costal margin, multilayered suturing using small bites technique and consider the use of a prophylactic mesh in high-risk patients. Nevertheless, the lack of evidence prevents from the possibility of making any strong recommendations.
RESUMO
We evaluate the 5-year results of a single-centre prospective randomized trial that compared cyclosporine microemulsion (CyA-me) in triple therapy (plus steroids and azathioprine) and Tacrolimus (Tac) in double therapy (plus steroids) for primary immunosuppression. One hundred adult patients undergoing liver transplantation were randomized to receive Tac (n=51) or CyA-me (n=49). Ten patients in group A, and thirty-one patients in group B had their main immunosuppressive agent switched. The switch was much more frequent from CyA-me to Tac (n=31; 62.3%), mainly because of lack of efficacy (n=12; 38.7%). Six of 10 patients were shifted from Tac to CyA-me for side effects. The clinical course of the majority of patients converted from CyA-me to Tac improved clearly after conversion. Donor age and acute rejection (number, severity and rejection free days) had a significative association with lack of efficacy in group B. In these series, the conversion to Tac from CyA-me could be accomplished safely, with an excellent long-term outcome.

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. The aim of this investigation was to assess the outcomes of abdominal wall reconstruction for subcostal incisional hernias through a new approach. The outcomes reported were short- and long-term complications, including recurrence, pain, and bulging. Quality of life was assessed with the European Registry for Abdominal Wall Hernias Quality of Life score. RESULTS: A total of 46 patients were identified. All patients underwent posterior component separation. Surgical site occurrences occurred in 10 patients (22%), with only 7 patients (15%) requiring procedural intervention. During a mean follow-up of 18 (range, 6-62), 1 (2%) case of clinical recurrence was registered. In addition, there were 8 (17%) patients with asymptomatic but visible bulging. The European Registry for Abdominal Wall Hernias Quality of Life score showed a statistically significant decrease in the 3 domains (pain, restriction, and cosmetic) of the postoperative compared with the preoperative scores. CONCLUSION: Posterior component separation technique for the repair of subcostal incisional hernias through the same incision is a safe procedure that avoids injury to the linea alba. It is associated with acceptable morbidity, low recurrence rate, and improvement in patients' reported outcomes.

The principle of targeted separation or weakening of individual components of the abdominal wall to relieve tension in the median line during major abdominal reconstruction has been known for over 30 years as anterior component separation (aCS) and is an established procedure. In search of alternatives with lower complication rates, posterior component separation (pCS) was developed; transversus abdominis release (TAR) is a nerve-sparing modification of pCS. With the ergonomic resources of robotics (e.g., angled instruments), TAR can be performed in a minimally invasive manner (r-TAR): hernia gaps of up to 14â¯cm can be closed and a large extraperitoneal mesh implanted. In this video article, the treatment of large incisional hernias using the rTAR technique is presented. Exemplary results of a cohort study in 13 consecutive patients are presented. The procedure is challenging, but our own results-as well as reports from the literature-are encouraging. The rTAR is becoming the pinnacle procedure for abdominal wall reconstruction.
