Abstract
Background Negative Pressure Therapy in closed incisions (ciNPT) after surgery has shown positive effects including reduction of Surgical Site Infection (SSI) incidence. In patients undergoing elective open incisional hernia repair, however, ciNPT is not standard care, perhaps due to high-quality evidence still not provided. This study hypothesizes that this patient group would benefit from ciNPT by reducing wound complications and improving postoperative quality of life. Method This is a multicenter Randomized Controlled Trial (RCT) including a total of 110 patients allocated in a 1:1 ratio with one intervention arm and one active control arm receiving ciNPT (i.e., Prevena™) and standard wound dressing, respectively. The primary outcome is the incidence of SSI at 30 days postoperatively and secondary outcomes are 1) pooled incidence of Surgical Site Occurrence (SSO), 2) patient-reported pain and satisfaction with the scar, and 3) hernia-related quality of life. Conclusion Patients undergoing elective open incisional hernia repair are fragile with a high risk of wound complication development. This multicenter RCT seeks to deliver the high-quality evidence needed to establish the role ciNPT must play for exactly this group with the aim of reducing SSI incidence and health economic costs, and finally improving quality of life. There are no theoretical or clinical experience of unwanted consequences of this treatment.

Abstract
BACKGROUND Repair of an umbilical hernia is most often considered the less important condition when concomitant with other abdominal surgery. Despite this, the evidence for a concomitant umbilical hernia repair is sparse. The aim of this nationwide cohort study is to compare the short- and long-term outcomes of primary umbilical hernia repair and umbilical hernia repair concomitant with other abdominal surgery. METHOD Data from the Danish Hernia Database and the National Patients Registry from January 2007 to December 2018 was merged, resulting in identification of patients receiving umbilical hernia concomitant to another abdominal surgery (laparoscopic inguinal hernia repair, laparoscopic cholecystectomy, and laparoscopic appendectomy). This group was propensity score matched with patients undergoing umbilical hernia repair as a primary procedure. Outcome data included 90-day readmission, 90-day reoperation, and operation for recurrence. RESULTS A total of 3365 primary umbilical hernia repairs and 2418 umbilical hernia repairs concomitant to other abdominal surgery were included. Readmission (10.5%, 255/2418) and reoperation (3.8%, 93/2418) rates within 90 days were decreased for umbilical hernia repairs concomitant to other abdominal surgery, compared with primary umbilical hernia repairs (22.7%, 765/3365) and (10.5%, 255/3365), P < 0.001 and P < 0.001, respectively. The rate of operation for recurrence was significantly increased for primary repairs (4.2%, 141/3365), compared with repairs concomitant to other abdominal surgery (3.2%, 77/2418), P = 0.014. CONCLUSION Outcome in umbilical hernia repair performed concomitant to laparoscopic inguinal hernia repair, elective or emergency laparoscopic cholecystectomy, or laparoscopic appendectomy is comparable to umbilical hernia repair without concomitant surgery.

Abstract
PURPOSE The robotic platform is widely implemented; however, evidence evaluating outcomes of robotic ventral hernia repair is still lacking. The aim of the study was to evaluate the short-term outcomes after open and robot-assisted repair of primary ventral and incisional hernias. METHODS Nationwide register-based cohort study with data from the Danish Ventral Hernia Database and the National Danish Patients Registry was from January 1, 2017 to August 22, 2022. Robot-assisted ventral hernia repairs were propensity score matched 1:3 with open repairs according to the confounding variables defect size, Charlson comorbidity index score, and age. Logistic regression analyses were performed for factors associated with length of stay > 2 days, readmission, and reoperation within 90 days. RESULTS A total of 528 and 1521 patients underwent robot-assisted and open repair, respectively. The mean length of hospital stay in days was 0.5 versus 2.1 for robot-assisted and open approach, respectively (P < 0.001) and open approach was correlated with risk of length of stay > 2 days (OR 23.25, CI 13.80-39.17, P < 0.001). The incidence of readmission within 90 days of discharge was significantly lower after robot-assisted repair compared to open approach (6.2% vs. 12.1%, P < 0.001). Open approach was independently associated with increased risk of readmission (OR 21.43, CI 13.28-39.17, P = 0.005, P < 0.001). CONCLUSION Robot-assisted ventral hernia repair is safe and feasible and associated with shorter length of stay and decreased risk of readmission compared with open ventral hernia repair.

Abstract
PURPOSE Enhanced recovery after surgery (ERAS) protocols lead to reduced post-operative stay and improved outcomes after most types of abdominal surgery. Little is known about the optimal post-operative protocol after robotic ventral hernia repair (RVHR), including the potential limits of outpatient surgery. We report the results of an ERAS protocol after RVHR aiming to identify factors associated with overnight stay in hospital, as well as patient-reported pain levels in the immediate post-operative period. METHODS This was a prospective cohort study of consecutive patients undergoing RVHR. Patients were included in a prospective database, registering patient characteristics, operative details, pain and fatigue during the first 3 post-operative days and pre- and 30-day post-operative hernia-related quality of life, using the EuraHS questionnaire. RESULTS A total of 109 patients were included, of which 66 (61%) underwent incisional hernia repair. The most performed procedure was TARUP (robotic transabdominal retromuscular umbilical prosthetic hernia repair) (60.6%) followed by bilateral roboTAR (robotic transversus abdominis release) (19.3%). The mean horizontal fascial defect was 4.8 cm, and the mean duration of surgery was 141 min. In total, 78 (71.6%) patients were discharged on the day of surgery, and factors associated with overnight stay were increasing fascial defect area, longer duration of surgery, and transverse abdominis release. There was no association between post-operative pain and overnight hospital stay. The mean EuraHS score decreased significantly from 38.4 to 6.4 (P < 0.001). CONCLUSION An ERAS protocol after RVHR was associated with a high rate of outpatient procedures with low patient-reported pain levels.

Abstract
OBJECTIVE To examine the short-term outcomes after laparoscopic intraperitoneal onlay mesh (IPOM) compared with robot-assisted retromuscular repair of small to medium-sized ventral hernia. BACKGROUND With the introduction of a robot-assisted approach, retromuscular mesh placement is technically more feasible compared with laparoscopic IPOM, with potential gains for the patient, including avoidance of painful mesh fixation and intraperitoneal mesh placement. METHODS This was a nationwide cohort study of patients undergoing either laparoscopic IPOM or robot-assisted retromuscular repair of a ventral hernia with a horizontal fascial defect <7 cm in the period 2017 to 2022, matched in a 1:2 ratio using propensity scores. Outcomes included postoperative hospital length of stay, 90-day readmission, and 90-day operative reintervention, and multivariable logistic regression analysis was performed to adjust for the relevant confounder. RESULTS A total of 1136 patients were included for analysis. The rate of IPOM-repaired patients hospitalized > 2 days was more than 3 times higher than after robotic retromuscular repair (17.3% vs. 4.5%, P < 0.001). The incidence of readmission within 90 days postoperatively was significantly higher after laparoscopic IPOM repair (11.6% vs. 6.7%, P =0.011). There was no difference in the incidence of patients undergoing operative intervention within the first 90 days postoperatively (laparoscopic IPOM 1.9% vs. robot-assisted retromuscular 1.3%, P =0.624). CONCLUSIONS For patients undergoing first-time repair of a ventral hernia, robot-assisted retromuscular repair was associated with a significantly reduced incidence of prolonged length of postoperative hospital stay and risk of 90-day readmission compared to laparoscopic IPOM.

Abstract
INTRODUCTION Umbilical hernia is a frequent condition in patients with cirrhosis. The aim of the study was to evaluate the risks associated with umbilical hernia repair in patients with cirrhosis in the elective and emergency setting. Secondly, to compare patients with cirrhosis with a population of patients with equally severe comorbidities but without cirrhosis. METHODS Patients with cirrhosis who underwent umbilical hernia repair from January 1, 2007, to December 31, 2018, were included from the Danish Hernia Database. A control group of patients with a similar Charlson score (≥ 3) without cirrhosis was generated using propensity score matching. The primary outcome was postoperative re-intervention within 30 days following hernia repair. Secondary outcomes were mortality within 90 days and readmission within 30 days following hernia repair. RESULTS A total of 252 patients with cirrhosis and 504 controls were included. Emergency repair in patients with cirrhosis was associated with a significantly increased rate of re-intervention (54/108 (50%) vs. 24/144 (16.7%), P < 0.001), 30-day readmission rate (50/108 (46.3%) compared with elective repair vs. 36/144 (25%) (P < 0.0001)), and 90-day mortality (18/108 (16.7%) vs. 5/144 (3.5%), P < 0.001). Patients with cirrhosis were more likely to undergo a postoperative re-intervention compared with comorbid patients without cirrhosis (OR = 2.10; 95% CI [1.45-3.03]). CONCLUSION Patients with cirrhosis and other severe comorbidity undergo emergency umbilical hernia repair frequently. Emergency repair is associated with increased risk of poor outcome. Patients with cirrhosis undergo a postoperative reintervention more frequently than patients with other severe comorbidity undergoing umbilical hernia repair.

Abstract
BACKGROUND Spigelian hernia is a rare hernia of the abdominal wall. Due to lack of evidence, there is no standard recommendation for surgical technique of Spigelian hernia repair. The aim of this study was to evaluate the outcomes after open and laparoscopic, elective and emergency repair of Spigelian hernias on a nationwide basis. METHODS Nationwide data from the Danish Ventral Hernia Database and the National Patient Registry was assessed to analyze outcomes after Spigelian hernia repair. A total of 365 patients were operated for Spigelian hernia in Denmark from 2007 to 2018. Ninety-day readmission, 90-day reoperation and long-term operation for recurrence were evaluated, as well as possible differences between open and laparoscopic, and elective and emergency repairs. RESULTS Most of the patients (80.5%, 294/365) were operated by laparoscopic approach and 19.5% (71/365) were operated by open approach. Elective surgery was performed in 83.6% (305/365) of the patients and 16.4% (60/365) underwent emergency repair. There were no significant differences in 90-day readmission or reoperation rates between open or laparoscopic Spigelian hernia repairs, P = 0.778 and P = 0.531. Ninety-day readmission and 90-day reoperation rates were also comparable for elective versus emergency repair, P = 0.399 and P = 0.766. No difference was found in operation for recurrence rates between elective and emergency, nor open and laparoscopic Spigelian hernia repairs. CONCLUSIONS This study demonstrates that 16% of Spigelian hernia repairs are done in the emergency setting. Open and laparoscopic approach are comparable in terms of early readmission, reoperation, and recurrence rates.

Abstract
Rectus diastasis is defined by thinning and widening of linea alba and is a part of pregnancy. In some patients, the diastasis persists giving symptoms such as core instability, and cosmetic complaints. Treatment consists of exercise and surgery by either a plastic surgeon or a general surgeon. Lately, rectus diastasis has gained both national and international attention but it is not clear which patients will benefit from surgery or which operative technique has the best outcome. This review describes postgestational rectus diastasis and summarizes treatment possibilities based on the latest literature.

Abstract
Incisional and parastomal hernias are frequent complications after abdominal surgery. Patients with relevant symptoms should be referred to the local surgical department for diagnosis and indication for surgery. Patients with giant and parastomal hernias are referred to one of the five Danish regional hernia centres. Patients with parastomal hernias often benefit from being referred to a stoma nurse. The most frequent complications after hernia repair are wound complications and recurrence. In case of severe wound infection, incarceration, or strangulation the patient must always be referred acutely, as argued in this review.

Abstract
BACKGROUND In 2010, it was decided to centralize parastomal hernia repairs to five specialized hernia centres in Denmark to improve outcomes. The aim of this nationwide cohort study was to evaluate whether centralization of parastomal hernia repairs has had an impact on outcomes. Specifically, readmission, reoperation for complication, and operation for recurrence were analysed before and after centralization. METHODS By merging clinical and administrative outcome data from the Danish Hernia Database with those from the Danish National Patient Registry, all patients undergoing parastomal hernia repair in Denmark from 1 January 2007 to 31 December 2018 were included. Centralization was defined as having at least 70 per cent of procedures were performed at one of the five national centres. Readmission, reoperation, and recurrence rates for emergency and elective repairs were evaluated before and after centralization. RESULTS In total, 1062 patients were included. Median follow-up was 992 days. Overall, the centralization process took 7 years. For elective repairs, the readmission, reoperation, mortality, and recurrence rates were comparable before and after centralization, but more patients overall and more patients with co-morbidity were offered surgery after centralization. For emergency repairs, there was a significant reduction in rates of reoperation (from 44.9 per cent (48 of 107) to 23 per cent (14 of 62); P = 0.004) and mortality (from 10.3 per cent (11 of 107) to 2 per cent (1 of 62); P = 0.034) after centralization. CONCLUSION Centralization led to more elective operations and better outcomes when emergency repair was needed. Centralization of parastomal hernia repair led to more patients receiving elective repair and significantly improved outcomes after emergency repair.

Abstract
PURPOSE Burst abdomen is a serious complication requiring immediate surgical treatment. This study aimed to investigate the association between rectus diastasis and burst abdomen in patients undergoing emergency midline laparotomy. METHODS A single-center, retrospective, matched case-control study of patients undergoing emergency midline laparotomy from May 2016 to August 2021 was conducted. Cases (patients who suffered from burst abdomen) were matched 1:4 with controls based on age and sex. Rectus diastasis was evaluated on CT imaging and was defined as a distance of at least three centimeters between the rectus abdominis muscles, three centimeters above the umbilicus. Midline laparotomy aponeurosis closure was standardized during the study period, using a slowly absorbable suture, sutured continuously with small bites of five millimeters and a minimum suture-to-wound ratio of 4:1. The primary outcome was the association between rectus diastasis and burst abdomen, evaluated against other suspected risk factors including obesity, liver cirrhosis, previous laparotomy, midline hernias and active smoking in a multivariate analysis. RESULTS A total of 465 patients were included in the study, with 93 cases matched to 372 controls. Eighty-four patients had rectus diastasis (35.5% cases vs. 13.7% controls; p = < 0.001). Multivariate analysis found rectus diastasis significantly associated with burst abdomen (OR 3.06, 95% CI 1.71-5.47; p = < 0.001). No other suspected risk factors showed a significant association with burst abdomen. CONCLUSION Rectus diastasis was highly associated with an increased risk of burst abdomen after emergency midline laparotomy.

Abstract
BACKGROUND Incisional hernia is a frequent complication of abdominal wall incision. Surgical technique is an important risk factor for the development of incisional hernia. The aim of these updated guidelines was to provide recommendations to decrease the incidence of incisional hernia. METHODS A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was performed on 22 January 2022. The Scottish Intercollegiate Guidelines Network instrument was used to evaluate systematic reviews and meta-analyses, RCTs, and cohort studies. The GRADE approach (Grading of Recommendations, Assessment, Development and Evaluation) was used to appraise the certainty of the evidence. The guidelines group consisted of surgical specialists, a biomedical information specialist, certified guideline methodologist, and patient representative. RESULTS Thirty-nine papers were included covering seven key questions, and weak recommendations were made for all of these. Laparoscopic surgery and non-midline incisions are suggested to be preferred when safe and feasible. In laparoscopic surgery, suturing the fascial defect of trocar sites of 10 mm and larger is advised, especially after single-incision laparoscopic surgery and at the umbilicus. For closure of an elective midline laparotomy, a continuous small-bites suturing technique with a slowly absorbable suture is suggested. Prophylactic mesh augmentation after elective midline laparotomy can be considered to reduce the risk of incisional hernia; a permanent synthetic mesh in either the onlay or retromuscular position is advised. CONCLUSION These updated guidelines may help surgeons in selecting the optimal approach and location of abdominal wall incisions.

Abstract
Patients with cirrhosis undergoing emergency umbilical hernia repair have increased risk of fatal complications. Of all patients with cirrhosis and umbilical hernia, 43% undergo emergency hernia repair, and thus the feasibility of elective procedures in this patient group was examined. This review found that medical and wound-related complications were the most frequent after umbilical hernia repair in patients with cirrhosis. Accordingly, additional evidence is needed to evaluate methods allowing for elective umbilical hernia repair in patients with cirrhosis.

Abstract
BACKGROUND Umbilical hernia is a common and potential serious condition in patients with cirrhosis. This systematic review evaluated the risks associated with emergency and elective hernia repair in patients with cirrhosis. METHODS Systematic review of clinical trials identified through manual and electronic searches in several databases (last update November 2021). The primary random-effects meta-analyses evaluated mortality in patients with or without cirrhosis or following emergency versus elective repair. The quality of the evidence was assessed using GRADE and Newcastle Ottawa Scale. RESULTS Thirteen prospective and 10 retrospective studies including a total of 3229 patients were included. The evidence was graded as very low quality for all outcomes (mortality and postoperative complications within 90 days). In total 191 patients (6%) died after undergoing umbilical hernia repair. Patients with cirrhosis were more than eight times as likely to die after surgery compared with patients without cirrhosis [OR = 8.50, 95% CI (1.91-37.86)] corresponding to 69 more deaths/1000 patients. Among patients with cirrhosis, mortality was higher after emergency versus elective repair [OR = 2.67, 95% CI (1.87-3.97)] corresponding to 52 more deaths/1000 patients. Postoperative complications were more common in patients with cirrhosis compared with patients without cirrhosis. CONCLUSION Patients with cirrhosis undergoing emergency umbilical hernia repair have a considerably increased risk of death and severe complications. Accordingly, additional evidence is needed to evaluate methods that would allow elective umbilical hernia repair in patients with cirrhosis.

Abstract
BACKGROUND The definition, classification and management of rectus diastasis (RD) are controversial in the literature and a variety of different surgical treatments have been described. This article reports on the European Hernia Society (EHS) Clinical Practice Guideline for RD. METHOD The Guideline group consisted of eight surgeons. The Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done in November 2018 and updated in November 2019 and October 2020. Nine Key Questions (KQs) were formulated. RESULTS Literature reporting on the definition, classification, symptoms, outcomes and treatments was limited in quality, leading to weak recommendations for the majority of the KQs. The main recommendation is to define RD as a separation between rectus muscles wider than 2 cm. A new classification system is suggested based on the width of muscle separation, postpregnancy status and whether or not there is a concomitant hernia. Impaired body image and core instability appear to be the most relevant symptoms. Physiotherapy may be considered before surgical management. It is suggested to use linea alba plication in patients without concomitant hernia and a mesh-based repair of RD with concomitant midline hernias. CONCLUSION RD should be defined as a separation of rectus muscles wider than 2 cm and a new classification system is suggested.

Abstract
Background Although laparoscopic repair of incisional hernias decreases the incidence of wound complications compared with open repair, there has been rising concern related to intraperitoneal mesh placement. The aim of this study was to examine outcomes after open or laparoscopic elective incisional hernia mesh repair on a nationwide basis. Methods This study analysed merged data from the Danish Hernia Database and the National Patient Registry on perioperative information, 90-day readmission, 90-day reoperation for complication, and long-term operation for hernia recurrence among patients who underwent primary repair of an incisional hernia between 2007 and 2018. Results A total of 3090 (57.5 per cent) and 2288 (42.5 per cent) patients had surgery by a laparoscopic and open approach respectively. The defect was closed in 865 of 3090 laparoscopic procedures (28.0 per cent). The median follow-up time was 4.0 (i.q.r. 1.8–6.8) years. Rates of readmission (502 of 3090 (16.2 per cent) versus 442 of 2288 (19.3 per cent); P = 0.003) and reoperation for complication (216 of 3090 (7.0 per cent) versus 288 of 2288 (12.5 per cent); P < 0.001) were significantly lower for laparoscopic than open repairs. Reoperation for bowel obstruction or bowel resection was twice as common after laparoscopic repair compared with open repair (20 of 3090 (0.6 per cent) versus 6 of 2288 (0.3 per cent); P = 0.044). Patients were significantly less likely to undergo repair of recurrence following laparoscopic compared with open repair of defect widths 2–6 cm (P = 0.002). Conclusion Laparoscopic intraperitoneal mesh repair for incisional hernia should still be considered for fascial defects between 2 and 6 cm, because of decreased rates of early complications and repair of hernia recurrence compared with open repair.

Abstract
INTRODUCTION Incisional hernia is common after abdominal surgery. Watchful waiting carries the risk of incarceration and a need for emergency intervention. The aim of this study was to examine the risk of postoperative complications after emergency versus elective incisional hernia repair. METHODS Patients above 18 years of age undergoing open incisional hernia repair in Denmark in 2017-2018 were identified in the Danish Ventral Hernia Database. Patients were grouped according to elective or emergency hernia repair. The primary outcome was postoperative complications requiring operative intervention within 90 days, and the secondary outcome was postoperative length of stay. RESULTS We included 1050 patients, of whom 882 were admitted for elective and 168 for emergency operation. Patients undergoing emergency repair were older (64.7 years vs 59.2 years, p < 0.001), more often smokers (25.8% vs 13.6%, p = 0.003), and more often had a Charlson comorbidity score ⩾2 (26.8% vs 19.2%, p = 0.005) compared to patients undergoing elective repair. In a multivariate regression analysis, emergency compared to elective operation (OR = 2.71, 95% CI = 1.4-5.25, p = 0.003) and retromuscular compared to onlay mesh placement (OR = 2.14, 95% CI = 1.08-4.24, p = 0.013) were factors significantly associated with increased risk of postoperative complications. In a subgroup analysis including only emergency repairs, risk of complications after retromuscular mesh placement was even higher (OR = 10.12, 95% CI = 1.81-56.68, p = 0.008). CONCLUSION Emergency incisional hernia repair was associated with increased risk of postoperative complications and this risk was accentuated with retromuscular mesh placement. The use of retromuscular mesh in the emergency setting should be avoided, and the abdominal wall could either be closed by sutures or additional onlay mesh.

Abstract
BACKGROUND Enhanced recovery after surgery (ERAS) are evidence-based protocols associated with improved patient outcomes. The use of ERAS pathways is well documented in various surgical specialties. The aim of this systematic review and meta-analysis was to examine the efficacy of ERAS protocols in patients undergoing abdominal wall reconstruction (AWR). METHODS This systematic review and meta-analysis were reported according to PRISMA and MOOSE guidelines. The databases PubMed, EMBASE, CINAHL, Web of Science and Cochrane Library were searched for original studies comparing ERAS with standard care in patients undergoing AWR. The primary outcome was length of stay (LOS) and secondary outcomes were readmission and surgical site infection (SSI) and/or surgical site occurrences (SSO). RESULTS Five studies were included in the meta-analysis. All were retrospective cohort studies including 453 patients treated according to ERAS protocols, and 494 patients treated according to standard care. The meta-analysis demonstrated that patients undergoing AWR managed with ERAS had a mean 0.89 days reduction in LOS compared with patients treated with standard care (95% CI - 1.70 to - 0.07 days, p = 0.03). There was no statistically significant difference in readmission rate (OR 1.00, 95% CI 0.53 to 1.87, p = 1.00) or SSI/SSO (OR 1.19, 95% CI 0.67 to 2.11, p = 0.56) between groups. CONCLUSIONS The use of ERAS in patients undergoing AWR was found to significantly reduce LOS without increasing the readmission rate or SSI/SSO. Based on the existing literature, ERAS protocols should be implemented for patients undergoing AWR.

Abstract
BACKGROUND Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short- and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias. METHODS The guideline group consisted of surgeons from Europe and North America including members from the European Hernia Society and the Americas Hernia Society. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists, and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done on 1 May 2018, and updated on 1 February 2019. RESULTS Literature reporting specifically on umbilical and epigastric hernias was limited in quantity and quality, resulting in a majority of the recommendations being graded as weak, based on low-quality evidence. The main recommendation was to use mesh for repair of umbilical and epigastric hernias to reduce the recurrence rate. Most umbilical and epigastric hernias may be repaired by an open approach with a preperitoneal flat mesh. A laparoscopic approach may be considered if the hernia defect is large, or if the patient has an increased risk of wound morbidity. CONCLUSION This is the first European and American guideline on the treatment of umbilical and epigastric hernias. It is recommended that symptomatic umbilical and epigastric hernias are repaired by an open approach with a preperitoneal flat mesh.

Abstract
Background Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management. Methods The guideline group consisted of surgeons from the European and Americas Hernia Societies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used in formulating the recommendations. The Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists were used to evaluate the quality of full‐text papers. A systematic literature search was performed on 1 May 2018 and updated 1 February 2019. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was followed. Results Literature was limited in quantity and quality. A majority of the recommendations were graded as weak, based on low quality of evidence. In patients with cirrhosis or on dialysis, a preperitoneal mesh repair is suggested. Subsequent pregnancy is a risk factor for recurrence. Repair should be postponed until after the last pregnancy. For patients with a concomitant rectus diastasis or those with a Spigelian or lumbar hernia, no recommendation could be made for treatment strategy owing to lack of evidence. Conclusion This is the first European and American guideline on the treatment of umbilical and epigastric hernias in patients with special conditions, including Spigelian and lumbar hernias. All recommendations were weak owing to a lack of evidence. Further studies are needed on patients with rectus diastasis, Spigelian and lumbar hernias.

Abstract
Traumatic rectal lesions can be seen in both blunt and penetrating traumas and are associated with a high morbidity and high mortality. This is a review of the literature on diagnosis and treatment of intra- and extraperitoneal rectal lesions. There is a consensus, that intraperitoneal rectal lesions should be treated with primary repair alone. There is more debate concerning the extraperitoneal lesions, and the level of evidence is generally low. We suggest, that extraperitoneal rectal lesions should be treated with colostomy.

Abstract
BACKGROUND The aim of this systematic review and meta-analysis was to evaluate closure materials and suture techniques for emergency and elective laparotomies. The primary outcome was incisional hernia after 12 months, and the secondary outcomes were burst abdomen and surgical site infection. METHODS A systematic literature search was conducted until September 2017. The quality of the RCTs was evaluated by at least 3 assessors using critical appraisal checklists. Meta-analyses were performed. RESULTS A total of 23 RCTs were included in the meta-analysis. There was no evidence from RCTs using the same suture technique in both study arms that any suture material (fast-absorbable/slowly absorbable/non-absorbable) is superior in reducing incisional hernias. There is no evidence that continuous suturing is superior in reducing incisional hernias compared to interrupted suturing. When using a slowly absorbable suture for continuous suturing in elective midline closure, the small bites technique results in significantly less incisional hernias than a large bites technique (OR 0.41; 95% CI 0.19, 0.86). CONCLUSIONS There is no high-quality evidence available concerning the best suture material or technique to reduce incisional hernia rate when closing a laparotomy. When using a slowly absorbable suture and a continuous suturing technique with small tissue bites, the incisional hernia rate is significantly reduced compared with a large bites technique.

Abstract
This review updates the literature on surgical treatment algorithm for umbilical, epigastric and incisional hernias by proposing an algorithm. It is recommended, that small hernias (horizontal defect 0-2 cm) are repaired openly with sublay or onlay mesh with 1 cm mesh overlap. Medium-sized hernias (horizontal defect 2-6 cm) may be repaired laparoscopically with intraperitoneal mesh with at least 5 cm overlap or openly with sublay mesh. Open repair with sublay mesh is recommended for large hernias (6-10 cm). Complex hernias and transverse defects > 10 cm should be repaired in a specialised hernia centre.

Abstract
BACKGROUND AND AIMS Hernia formation is associated with alterations of collagen metabolism. Collagen synthesis and degradation cause a systemic release of products, which are measurable in serum. Recently, we reported changes in type V and IV collagen metabolisms in patients with inguinal and incisional hernia. The aim of this study was to determine if the altered collagen metabolism was persistent after hernia repair. MATERIAL AND METHODS Patients who had undergone repairs for inguinal hernia (n = 11) or for incisional hernia (n = 17) were included in this study. Patients who had undergone elective cholecystectomy served as controls (n = 10). Whole venous blood was collected 35-55 months after operation. Biomarkers for type V collagen synthesis (Pro-C5) and degradation (C5M) and those for type IV collagen synthesis (P4NP) and degradation (C4M2) were measured by a solid-phase competitive assay. RESULTS The turnover of type V collagen (Pro-C5/C5M) was slightly higher postoperatively when compared to preoperatively in the inguinal hernia group (P = 0.034). In addition, the results revealed a postoperatively lower type V collagen turnover level in the inguinal hernia group compared to controls (P = 0.012). In the incisional hernia group, the type V collagen turnover was higher after hernia repair (P = 0.004) and the postoperative turnover level was not different from the control group (P = 0.973). CONCLUSION Patients with an inguinal hernia demonstrated a systemic and persistent type V collagen turnover alteration. This imbalance of the collagen metabolism may be involved in the development of inguinal hernias.

Abstract
INTRODUCTION Surgical site infection (SSI) is a frequent complication of abdominal surgery causing increased morbidity. Triclosan-coated sutures are recommended to reduce SSI. The aim of this systematic review and meta-analysis was to evaluate the evidence from randomized controlled trials (RCT) comparing the rate of SSI in abdominal surgery when using triclosan-coated or uncoated sutures for fascial closure. METHODS A systematic literature search was conducted using Medline, EMBASE, the Cochrane library, CINAHL, Scopus and Web of Science including publications until August 2017. The quality of the RCTs was evaluated using critical appraisal checklists from SIGN. Meta-analyses and trial sequential analysis were performed with Review Manager v5.3 and TSA software, respectively. RESULTS Eight RCTs on abdominal wall closure were included in the meta-analysis. In an overall comparison including both triclosan-coated Vicryl and PDS sutures for fascial closure, triclosan-coated sutures were superior in reducing the rate of SSI (OR 0.67; 0.46-0.98). When evaluating PDS sutures separately, there was no effect of triclosan-coating on the rate of SSI (OR 0.85; 0.61-1.17). Trial sequential analysis showed that the required information size (RIS) of 797 patients for triclosan-coated Vicryl sutures was almost reached with an accrued information size (AIS) of 795 patients. For triclosan-coated PDS sutures an AIS of 2707 patients was obtained, but the RIS was estimated to be 18,693 patients. CONCLUSION Triclosan-coated Vicryl sutures for abdominal fascial closure decrease the risk of SSI significantly and based on the trial sequential analysis further RCTs will not change that outcome. There was no effect on SSI rate with the use of triclosan-coated PDS sutures for abdominal fascial closure, and it is unknown whether additional RCTs will change that.

Abstract
It is estimated that 15% of patients above 65 years of age are frail. Frail patients have significantly higher risk of post-operative complications when undergoing both elective and emergency surgery than patients who are not frail. Therefore, it is recommended that all patients above 65 years are frailty scored prior to a surgical procedure. It seems advisable to include the following items in a multimodal frailty score: evaluation of the patient's cognitive ability, functional status, nutritional status and pulmonary and cardiac function.

Abstract
BACKGROUND Hernia formation is a multifactorial disease involving important endogenous factors possibly affected by exogenous factors. Alterations in collagen composition seem to contribute to abdominal wall hernia formation, possibly related to increased collagen breakdown. The collagen composition appears altered in fascial tissue but also in skin biopsies, suggesting that the collagen alterations are systemic. More pronounced collagen alterations are found in patients with hernia recurrences. Hypothetically, primary inguinal hernias are formed due to a systemic predisposition to altered connective tissue, whereas impaired healing influences on the development of incisional hernias and hernia recurrences. The overall objective of this thesis was to investigate the collagen turnover systemically and locally in patients with primary inguinal hernia, multiple hernias and incisional hernia. METHODS AND RESULTS In a systematic literature review, a total of 55 original articles were reviewed evaluating connective tissue alterations in patients with abdominal wall hernias. Patients with inguinal and incisional hernias exhibit a decreased type I to III collagen ratio in fascia and skin biopsies with the most pronounced alterations found in patients with direct inguinal hernia and hernia recurrence. An increased level of MMP-2 was reported in patients with inguinal hernias. In a nationwide study from the Danish Hernia Database, 92,283 patients with an inguinal hernia repair were identified from January 1998 until June 2010. A total of 843 patients were also registered with a ventral hernia repair. Direct (OR = 1.28 [95% C.I. 1.08-1.51]) and recurrent (OR = 1.76 [95% C.I. 1.39-2.23]) inguinal hernia repairs were significantly associated with ventral hernia repair compared to indirect inguinal hernia repair after adjustment for gender, age and surgical approach. In a multivariable subgroup analysis, direct and recurrent inguinal hernia repair were associated with primary ventral hernia surgery, whereas only recurrent inguinal hernia repair was associated with secondary ventral hernia surgery. In a cohort of 305 patients followed up a median of 3.7 years after emergency or elective laparotomy, a total of 79 patients were identified with an incisional hernia. Patients were subgrouped based on the identified risk factors male gender and smoking in eight groups with nine patients in each. Pooled serum samples were screened for MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-12, MMP-13, TIMP-1, TIMP-2, and TIMP-4 with a multiarray and zymography. The screening indicated differences in MMP-9 and TIMP-1, which were measured in serum samples of the whole patient cohort with ELISA. There were no differences in systemic MMP-9 and TIMP-1 levels between patients with and without incisional hernia. Patients were enrolled consecutively in four groups: 1) patients undergoing elective laparoscopic cholecystectomy without hernias (N = 18), patients operated on for 2) primary unilateral inguinal hernia (N = 17), 3) multiple hernias defined as three or more primary hernias (N = 21) and 4) incisional hernia (N = 25). Venous blood was collected preoperatively. Pro-MMP-2 and pro-MMP-9 were measured in serum by gelatine zymography, and there were no significant differences between hernia patients and controls. Furthermore, serological biomarkers for type I, III, IV and V collagen turnover were measured in serum by solid-phase competitive immunoassays. In patients with inguinal hernia, type III and V collagen turnover were significantly decreased, whereas type IV collagen turnover was significantly increased. In incisional hernia patients, type V collagen turnover was significantly decreased, whereas type IV collagen turnover was significantly increased. Type IV collagen turnover seem to predict the presence of both inguinal and incisional hernia. An ePTFE tube was implanted perioperatively in all four patient groups and explanted on the tenth post-operative day. Newly synthesized granulation tissue in the ePFTE tube represents the patients' wound healing potential. Hydroxyproline levels were measured as a marker for total collagen deposition and were unaltered in hernia patients compared to controls. Pro-MMP-2 and pro-MMP-9 levels in the PTFE tubes did not differ between hernia patients and controls. A fascia transversalis biopsy was excised perioperatively in all four patient groups. There were no significant differences between hernia patients and controls in total collagen concentration or morphology of the fascia transversalis.
CONCLUSIONS Direct and recurrent inguinal hernia repair are associated with ventral hernia repair, suggesting a systemic predisposition to the hernia disease. MMPs are not suitable as serum biomarkers for inguinal or incisional hernia disease. Serum biomarkers for collagen turnover are altered in both inguinal and incisional hernia patients; specifically markers for type IV collagen turnover seem to predict the presence of hernias. A systemic biomarker predicting hernia disease would be useful to plan a tailored surgical strategy for the individual patient.

Abstract
BACKGROUND Throughout life, inguinal hernia develops in approximately every fourth man, some of whom develop multiple hernias. If patients at risk of developing multiple hernias could be identified by a serologic biomarker, treatment might be able to be tailored and improved. Evidence suggests that abdominal wall hernia formation is associated with altered collagen metabolism. The aim of this study was to evaluate biomarkers for type IV and V collagen turnover in patients with multiple hernias and control subjects without hernia. METHODS Venous blood was collected from 88 men (mean age, 62 years) with a history of more than 3 hernia repairs and 86, age-matched men without hernias. Biomarkers for synthesis of collagen type IV (P4NP) and type V (P5CP) as well as breakdown (C4M and C5M) were measured in serum by validated, solid-phase, competitive assays. Collagen turnover was indicated by the ratio between the biomarker for synthesis and breakdown. RESULTS Type IV collagen turnover was 1.4-fold increased in patients with multiple hernias compared to control subjects (P < .001), whereas type V collagen turnover was 1.7-fold decreased (P < .001). Diagnostic power of P5CP was 0.83 (95%C.I.:0.77-0.89), P < .001. CONCLUSION Patients with multiple hernias exhibit increased turnover of type IV collagen and a decreased turnover of type V collagen, demonstrating systemically altered collagen turnover. Biomarkers for type V collagen turnover may be used to identify patients at risk for or with multiple hernias.

Abstract
PURPOSE There is no consensus as to the treatment strategy for abdominal wall hernias in fertile women. This study was undertaken to review the current literature on treatment of abdominal wall hernias in fertile women before or during pregnancy. METHODS A literature search was undertaken in PubMed and Embase in combination with a cross-reference search of eligible papers. RESULTS We included 31 papers of which 23 were case reports. In fertile women undergoing sutured or mesh repair, pain was described in a few patients during the last trimester of a subsequent pregnancy. Emergency surgery of incarcerated hernias in pregnant women, as well as combined hernia repair and cesarean section appears as safe procedures. No major complications were reported following hernia repair before or during pregnancy. The combined procedure of elective cesarean section and abdominal wall hernia repair was reported in 102 patients without major complications. CONCLUSIONS The literature on abdominal wall hernia and pregnancy is sparse. Abdominal wall hernia repair with suture or mesh may cause pain in the last trimester of a subsequent pregnancy.

Abstract
BACKGROUND Recent improvements in incisional hernia repair have led to lower rates of recurrence. As a consequence, increasing attention has been paid to patient-reported outcomes after surgery. However, there is no consensus on how to measure patients' quality of life after incisional hernia repair. The aim of this systematic review was to analyze existing standardized methods to measure quality of life after incisional hernia repair. DATA SOURCES A PubMed and Embase search was carried out together with a cross-reference search of eligible papers, giving a total of 26 included studies. CONCLUSIONS Different standardized methods for measurement of quality of life after incisional hernia repair are available, but no consensus on the optimal method, timing, or length of follow-up exist. International guidelines could help standardization, enabling better comparison between studies.

Abstract
Abstract
Background
Previous studies have reported a higher prevalence of inguinal hernia in patients with abdominal aortic aneurysm (AAA). The aim of this study was to explore the association between inguinal hernia and AAA in a large population-based cohort of men who had screening for AAA.
Methods
A total of 18 331 men aged 65–76 years had ultrasound screening for AAA in the Central Region of Denmark from 2008 to 2010. The Danish National Patient Registry was interrogated, and screened men registered with an inguinal hernia from 1977 to 2011 were identified. The association between inguinal hernia and AAA was assessed by multiple logistic regression analysis.
Results
The prevalence of AAA was 3.3 per cent (601 of 18 331). A total of 2936 (16.0 per cent) of the 18 331 patients were registered with a diagnosis of inguinal hernia or hernia repair. Inguinal hernia was not associated with AAA: crude odds ratio (OR) 0.86 (95 per cent confidence interval 0.68 to 1.09) and adjusted OR 0.94 (0.75 to 1.20).
Conclusion
In contrast to smaller patient-based studies, this large population-based study found no association between inguinal hernia and AAA.

Abstract
Incisional hernia formation is a common complication to laparotomy and possibly associated with alterations in connective tissue metabolism. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are closely involved in the metabolism of the extracellular matrix. Our aim was to study serum levels of multiple MMPs and TIMPs in patients with and without incisional hernia. Out of 305 patients who underwent laparotomy, 79 (25.9%) developed incisional hernia over a median follow-up period of 3.7 years. Pooled sera from a subset (n = 72) of these patients were screened for MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-12, MMP-13, TIMP-1, TIMP-2, and TIMP-4 using a multiplex sandwich fluorescent immunoassay supplemented with gelatin zymography. The screening indicated differences in serum MMP-9 and TIMP-1 levels. Consequently, MMP-9 and TIMP-1 levels were measured in serum in the whole patient cohort with enzyme-linked immunosorbent assay. There were no significant differences in either MMP-9 (p = 0.411) or TIMP-1 (p = 0.679) levels between hernia and hernia-free patients. MMP-9 was significantly increased in smokers compared with nonsmokers (p = 0.016). In conclusion, a possible involvement of MMPs and TIMPs in the pathogenesis of incisional hernia formation was not reflected systemically.

Abstract
BACKGROUND A systemically altered connective tissue metabolism has been demonstrated in patients with abdominal wall hernias. The most pronounced connective tissue changes are found in patients with direct or recurrent inguinal hernias as opposed to patients with indirect inguinal hernias. The aim of the present study was to assess whether direct or recurrent inguinal hernias are associated with an elevated rate of ventral hernia surgery. METHODS In the nationwide Danish Hernia Database, a cohort of 92,457 patients operated on for inguinal hernias was recorded from January 1998 until June 2010. Eight-hundred forty-three (0.91 %) of these patients underwent a ventral hernia operation between January 2007 and June 2010. A multivariate logistic regression analysis was applied to assess an association between inguinal and ventral hernia repair. RESULTS Direct (Odds Ratio [OR] = 1.28 [95 % CI, 1.08-1.51]) and recurrent (OR = 1.76, [95 % CI, 1.39-2.23]) inguinal hernias were significantly associated with ventral hernia repair after adjustment for age, gender, and surgical approach (open or laparoscopic). CONCLUSIONS Patients with direct and recurrent inguinal herniation are more prone to ventral hernia repair than patients with indirect inguinal herniation. This is the first study to show that herniogenesis is associated with type of inguinal hernia.

Abstract
This study concludes that a modified single-incision procedure for cholecystectomy using 2 regular ports inserted through the umbilicus can be performed at lower cost than a conventional 4-port procedure. Background and Objectives: Specially designed surgical instruments have been developed for single-incision laparoscopic surgery, but high instrument costs may impede the implementation of these procedures. The aim of this study was to compare the cost of operative implements used for elective cholecystectomy performed as conventional laparoscopic 4-port cholecystectomy or as single-incision laparoscopic cholecystectomy. Methods: Two consecutive series of patients undergoing single-incision laparoscopic cholecystectomy were assessed: (1) single-incision cholecystectomy using a commercially available multichannel port (n=80) and (2) a modified single-incision cholecystectomy using 2 regular trocars inserted through the umbilicus (n=20) with transabdominal sutures for gallbladder mobilization (puppeteering technique). Patients who underwent conventional 4-port cholecystectomy during the same time period (n=100) were selected as controls. Results: The instrumental cost of the single-incision cholecystectomy using a commercial port was significantly higher (median, $1123) than the cost for conventional 4-port (median $441, P < .0005) and modified single-incision cholecystectomy (median $342, P < .0005). The cost of the modified single-incision procedure was significantly lower than that for the 4-port cholecystectomy (P < .0005). Conclusion: The modified single-incision procedure using 2 regular ports inserted through the umbilicus can be performed at lower cost than conventional 4-port cholecystectomy.

Abstract
BACKGROUND The aetiology and pathogenesis of abdominal wall hernia formation is complex. Optimal treatment of hernias depends on a full understanding of the pathophysiological mechanisms involved in their formation. The aim of this study was to review the literature on specific collagen alterations in abdominal wall hernia formation. METHODS A computer-assisted search of the medical databases PubMed and Embase was performed, together with a cross-reference search of eligible papers. RESULTS Fifty-two papers were included. Collagen alteration depended on the type of hernia; there were more pronounced changes in patients with a direct inguinal hernia than in those with an indirect inguinal hernia, recurrent inguinal hernia or incisional hernia. A consistent finding was a significant increase in immature type III collagen relative to the stronger type I collagen in patients with a hernia. This resulted in thinner collagen fibres with a correspondingly diminished biomechanical strength. It has been suggested that these alterations are due to variation in the synthesis, maturation or degradation of collagen by matrix metalloproteinases, in combination or alone. CONCLUSION Hernia formation and recurrence is associated with altered collagen metabolism manifested by a decreased type I:III collagen ratio.
