RESUMEN
BACKGROUND: The Trans Rectus Sheath Extra-Peritoneal Procedure (TREPP) is an open procedure in which the mesh is placed in the preperitoneal space and is therefore associated with less chronic post-operative inguinal pain. TREPP is primarily performed under general or spinal anesthesia, however, it is also possible to perform under sedation and local anesthesia with potentially advantages. This retrospective feasibility pilot study investigates the safety and efficiency of TREPP under local anesthesia in the outpatient clinic in comparison with Lichtenstein. METHODS: Between 2019 and 2022, all patients who underwent an elective inguinal hernia repair under local anesthesia in the outpatient clinic operation theatre were assessed. 34 patients in the TREPP group and 213 patients in the Lichtenstein group were included. Outcomes were complications, operating time, theatre time, and early inguinal hernia recurrence within 8 weeks and 6 months post-operatively. RESULTS: No significant differences in complications such as wound infection, hematoma, seroma, urine retention and early recurrence between TREPP and Lichtenstein were found. Post-operative pain at 8 weeks was not significantly higher after Lichtenstein (8.8% vs. 18.8%, P = 0.22). Operating time (21.0 (IQR: 16.0-27.3) minutes vs. 39.0 (IQR: 31.5-45.0) minutes, P < 0.001) and theatre time (37.5 (IQR: 30.8-42.5) minutes vs. 54.0 (IQR: 46.0-62.0) minutes, P < 0.001) was significantly shorter for TREPP. CONCLUSION: This pilot study showed that TREPP appears to be feasible to perform safely under local anesthesia with comparable complication rates and substantially shorter operation time than Lichtenstein. These results justify further research with a larger study population and a longer period of follow up in order to provide firm conclusions.

BACKGROUND: Patients often need admission at an Intensive Care Unit (ICU), immediately after complex abdominal wall reconstruction (CAWR). Lack of ICU resources requires adequate patient selection for a planned postoperative ICU admission. Risk stratification tools like Fischer score and Hernia Patient Wound (HPW) classification may improve patient selection. This study evaluates the decision-making process in a multidisciplinary team (MDT) on justified ICU admissions for patients after CAWR. METHODS: A pre-Covid-19 pandemic cohort of patients, discussed in a MDT and subsequently underwent CAWR between 2016 and 2019, was analyzed. A justified ICU admission was defined by any intervention within the first 24 h postoperatively, considered not suitable for a nursing ward. The Fischer score predicts postoperative respiratory failure by eight parameters and a high score (> 2) warrants ICU admission. The HPW classification ranks complexity of hernia (size), patient (comorbidities) and wound (infected surgical field) in four stages, with increasing risk for postoperative complications. Stages II-IV point to ICU admission. Accuracy of the MDT decision and (modifications of) risk-stratification tools on justified ICU admissions were analyzed by backward stepwise multivariate logistic regression analysis. RESULTS: Pre-operatively, the MDT decided a planned ICU admission in 38% of all 232 CAWR patients. Intra-operative events changed the MDT decision in 15% of all CAWR patients. MDT overestimated ICU need in 45% of ICU planned patients and underestimated in 10% of nursing ward planned patients. Ultimately, 42% went to the ICU and 27% of all 232 CAWR patients were justified ICU patients. MDT accuracy was higher than the Fischer score, HPW classification or any modification of these risk stratification tools. CONCLUSION: A MDT's decision for a planned ICU admission after complex abdominal wall reconstruction was more accurate than any of the other risk-stratifying tools. Fifteen percent of the patients experienced unexpected operative events that changed the MDT decision. This study demonstrated the added value of a MDT in the care pathway of patients with complex abdominal wall hernias.

BACKGROUND: In recent years, the use of Indocyanine Green (ICG) fluorescence-guided surgery during open and laparoscopic procedures has exponentially expanded across various clinical settings. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference on this topic with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS: An expert panel of surgeons has been selected and invited to participate to this project. Systematic reviews of the PubMed, Embase and Cochrane libraries were performed to identify evidence on potential benefits of ICG fluorescence-guided surgery on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by the panel; they were then submitted to all EAES members through a two-rounds online survey and results presented at the EAES annual congress, Barcelona, November 2021. RESULTS: A total of 18,273 abstracts were screened with 117 articles included. 22 statements and 16 recommendations were generated and approved. In some areas, such as the use of ICG fluorescence-guided surgery during laparoscopic cholecystectomy, the perfusion assessment in colorectal surgery and the search for the sentinel lymph nodes in gynaecological malignancies, the large number of evidences in literature has allowed us to strongly recommend the use of ICG for a better anatomical definition and a reduction in post-operative complications. CONCLUSIONS: Overall, from the systematic literature review performed by the experts panel and the survey extended to all EAES members, ICG fluorescence-guided surgery could be considered a safe and effective technology. Future robust clinical research is required to specifically validate multiple organ-specific applications and the potential benefits of this technique on clinical outcomes.

AIM: To assess the added value of Near InfraRed Fluorescence (NIRF) imaging during laparoscopic cholecystectomy. METHODS: This international multicentre randomized controlled trial included participants with an indication for elective laparoscopic cholecystectomy. Participants were randomised into a NIRF imaging assisted laparoscopic cholecystectomy (NIRF-LC) group and a conventional laparoscopic cholecystectomy (CLC) group. Primary end point was time to 'Critical View of Safety' (CVS). The follow-up period of this study was 90 postoperative days. An expert panel analysed the video recordings after surgery to confirm designated surgical time points. RESULTS: A total of 294 patients were included, of which 143 were randomized in the NIRF-LC and 151 in the CLC group. Baseline characteristics were equally distributed. Time to CVS was on average 19 min and 14 s for the NIRF-LC group and 23 min and 9 s for the CLC group (p 0.032). Time to identification of the CD was 6 min and 47 s and 13 min for NIRF-LC and CLC respectively (p < 0.001). Transition of the CD in the gallbladder was identified after an average of 9 min and 39 s with NIRF-LC, compared to 18 min and 7 s with CLC (p < 0.001). No difference in postoperative length of hospital stay nor occurrence of postoperative complications was found. ICG related complications were limited to one patient who developed a rash after injection of ICG. CONCLUSION: Use of NIRF imaging in laparoscopic cholecystectomy provides earlier identification of relevant extrahepatic biliary anatomy: earlier achievement of CVS, cystic duct visualisation and visualisation of both cystic duct and cystic artery transition into the gallbladder.

BACKGROUND: Parastomal hernia after ileal conduit urinary diversion is an underestimated and undertreated clinical entity, which heavily impairs patients' quality of life due to symptoms of pain, leakage, application or skin problems. As for all gastrointestinal stomata the best surgical repair technique has yet to be determined. Thereby, surgery for ileal conduit parastomal hernias poses some specific perioperative challenges. This review aims to give an overview of current evidence on the surgical treatment of parastomal hernia after cystectomy and ileal conduit urinary diversion, and on the use of prophylactic mesh at index surgery in its prevention. METHODS: A systematic review was performed according to PRISMA-guidelines. The electronic databases Embase, PubMed, Cochrane Library, and Web of Science were searched. Studies were included if they presented postoperative outcomes of patients undergoing surgical treatment of parastomal hernia at the ileal conduit site, irrespective of the technique used. A search was performed to identify additional studies on prophylactic mesh in the prevention of ileal conduit parastomal hernia, that were not identified by the initial search. RESULTS: Eight retrospective case-series were included for analysis, reporting different surgical techniques. If reported, highest complication rate was 45%. Recurrence rates varied highly, ranging from 0 to 80%. Notably, lower recurrence rates were reported in studies with shorter follow-up. Overall, available data suggest significant morbidity after the surgical treatment of ileal conduit parastomal hernias. Data from five conference abstracts on the matter were retrieved, and systematically reported. Regarding prophylactic mesh in the prevention of ileal conduit parastomal hernia, 5 communications were identified. All of them used keyhole mesh in a retromuscular position, and reported on favorable results in the mesh group without an increase in mesh-related complications. CONCLUSION: Data on the surgical treatment of ileal conduit parastomal hernias and the use of prophylactic mesh in its prevention is scarce. Given the specific perioperative challenges and the paucity of reported results, more high-quality evidence is needed to determine the optimal treatment of this specific surgical problem. Initial results on the use of prophylactic mesh in the prevention of ileal conduit parastomal hernias seem promising.

Volatile organic compounds (VOCs) in exhaled breath have the potential to be used as biomarkers for screening and diagnosis of diseases. Clinical studies are often complicated by both modifiable and non-modifiable factors influencing the composition of VOCs in exhaled breath. Small laboratory animal studies contribute in obtaining fundamental insight in alterations in VOC composition in exhaled breath and thereby facilitate the design and analysis of clinical research. However, long term animal experiments are often limited by invasive breath collection methods and terminal experiments. To overcome this problem, a novel device was developed for non-invasive breath collection in mice using glass nose-only restrainers thereby omitting the need of anesthetics. C57Bl/6 J mice were used to test reproducibility and different air sampling settings for air-flow (ml min-1) and time (minutes). Exhaled air was collected on desorption tubes and analysed for VOCs by gas chromatography time-of-flight mass spectrometry (GC-tof-MS). In total 27 compounds were putatively identified and used to assess the variability of the VOC measurements in the breath collections. Best reproducibility is obtained when using an air flow of 185 ml min-1and a collection time of 20 min. Due to the non-invasive nature of breath collections in murine models, this device has the potential to facilitate VOC research in relation to disturbed metabolism and or disease pathways.

PURPOSE: Research papers involving animal studies often display poor reporting standards, leading to lower study reproducibility. We aim to determine the difference in reporting animal studies regarding abdominal wall hernia repair with mesh placement, before and after the publication of ARRIVE-2010 (Animal Research: Reporting of In Vivo Experiments) guidelines. Furthermore, we aim to present the most up-to-date reporting quality using the updated ARRIVE-2020 as criteria. METHODS: All animal studies concerning hernia repair with meshes were systematically searched. Articles published in the 5 years leading up to the ARRIVE-2010 (pre-ARRIVE) and articles within the last 5 years until the updated ARRIVE 2.0 (post-ARRIVE) were compared for overall species and specific species separately. Articles published last year were evaluated for presenting fully reported (sub)items. RESULTS: The number of fully reported (sub)items per article was on average significantly higher for pre-ARRIVE than post-ARRIVE for overall species (mean (SD) = 14.0 (2.8) vs. 12.6 (2.5), P < 0.001). The same applies to rabbit (mean (SD) = 14.8 (2.6) vs. 12.6 (2.6), P = 0.001) and pig studies (mean (SD) = 14.5 (2.7) vs. 11.6 (2.6), P = 0.004), with no significance in rat studies (mean (SD) = 13.6 (2.9) vs. 12.9 (2.3), P = 0.076). Significance was found in several (sub)items between pre-ARRIVE and post-ARRIVE (n = 7, 3, 8, and 3 for overall species, rat, rabbit, and pig studies, respectively). CONCLUSION: General reporting quality of animal experiments has been improved markedly by ARRIVE guidelines. However, more improvements are required considering the arrival of ARRIVE 2.0 guidelines.

PURPOSE: More interest in the treatment of rectus diastasis has been evoked lately. Following the postpartum females from a great distance, the middle-aged males living with obesity are the second most common group of rectus diastasis patients. Although gender differences are considered frequently in regard to cosmetic appearance and symptoms, it is less obvious in classifications and subsequent treatment strategies. Is a unisex approach of rectus diastasis still applicable? The lack of a firm answer warrants this review of the current literature. METHODS: An explorative free-text multi-database bibliographic search (Pubmed/CENTRAL/EMBASE/PEDro/Scholar) was performed with the focus on the rectus diastasis in males. Anticipating the limited references, the design was a non-systematic review. All studies, regardless of study type, language or time period, describing etiology, symptoms, classification and/or treatment options were eligible for inclusion. From the articles retrieved out of this search, additional references were identified by a manual search among the cited references. RESULTS: The multi-database search resulted in a total of 7633 records. Based on the title and abstract 95 records were full text assessed for eligibility. Eleven studies were identified as relevant, six by cross-reference and another four by hand-search were added to provide an insight in gender-specific aspects in rectus diastase. Hereditary causes are differences in collagen-like composition of types and concomitant abdominal aneurysm as well as gender differences in the linea alba architecture. Acquired etiology is distributed into both absolute pressure by visceral obesity and relative pressure caused by weight lifting or improper exercises. Furthermore, the impact of muscle thickness and age are considered as influencers of biomechanics. Gender differences can also play a role in symptoms of body image and core stability. It is known that there are anatomical differences between male and female persons; more transverse fibers are found in infra-umbilical region in women. In classifications the awareness of male rectus diastasis is limited, treatment outcome studies are scarce on males. CONCLUSION: An overview of male-specific aspects of rectus diastasis is provided, underlining that key aspects surrounding rectus diastasis in males differ from females. Although males are the minority of rectus diastasis patients, we recommend that the male rectus diastasis as a concept should be specifically acknowledged in classifications systems and study outcome reporting to evaluate this subgroup more accurately in the future.

BACKGROUND: In recent decades there has been growing interest in the use of volatile organic compounds (VOCs) in exhaled breath as biomarkers for the diagnosis of multiple variants of cancer. This review aimed to evaluate the diagnostic accuracy and current status of VOC analysis in exhaled breath for the detection of cancer in the digestive tract. METHODS: PubMed and the Cochrane Library database were searched for VOC analysis studies, in which exhaled air was used to detect gastro-oesophageal, liver, pancreatic, and intestinal cancer in humans, Quality assessment was performed using the QUADAS-2 criteria. Data on diagnostic performance, VOCs with discriminative power, and methodological information were extracted from the included articles. RESULTS: Twenty-three articles were included (gastro-oesophageal cancer n = 14, liver cancer n = 1, pancreatic cancer n = 2, colorectal cancer n = 6). Methodological issues included different modalities of patient preparation and sampling and platform used. The sensitivity and specificity of VOC analysis ranged from 66.7 to 100 per cent and from 48.1 to 97.9 per cent respectively. Owing to heterogeneity of the studies, no pooling of the results could be performed. Of the VOCs found, 32 were identified in more than one study. Nineteen were reported as cancer type-specific, whereas 13 were found in different cancer types. Overall, decanal, nonanal, and acetone were the most frequently identified. CONCLUSION: The literature on VOC analysis has documented a lack of standardization in study designs. Heterogeneity between the studies and insufficient validation of the results make interpretation of the outcomes challenging. To reach clinical applicability, future studies on breath analysis should provide an accurate description of the methodology and validate their findings.

PURPOSE: Complex ventral hernia repair (CVHR) encompasses patient optimization, primary fascial closure (PFC), mesh reinforcement and component separation technique (CST), if needed. High rates of complications after CST are still reported. Prehabilitation by managing pre-operative modifiable risk factors, like abdominal wall compliance, possibly reduces these rates. Compliance can be modified by intramuscular injection of Botulinum in the lateral abdominal wall muscles (LAWM). Paralysis leads to elongation of these muscles, which may facilitate PFC and/or prevent CST. Evidence to use Botulinum in hernia patients is scarce and fragmented. An update of evidence for the effect of Botulinum is presented. METHODS: A multi-database search was conducted for Botulinum studies in ventral hernia patients. A systematic review was performed to describe its primary effect on compliance (LAWM elongation) and secondary effects like PFC ± CST rate, complications and recurrence. RESULTS: 14 studies were included (377 patients) with a HDW of median 12 (10-15) cm. A typical intervention consisted of 200-300 U Botulinum in 3 points per hemi-abdomen under US guidance, > 2 weeks pre-operatively and evaluated by CT just before the operation. The primary effect was a median LAWM elongation of 4.0 cm per side without complications of the injection (four studies, 107 patients). The median PFC rate was 100%, CST rate 38%, wound-related complications 19%, medical complications 18% and recurrence 0% (14 studies). CONCLUSION: Botulinum safely elongates the abdominal wall muscles, but the level of evidence available remains low. Any patient in whom PFC is expected to be difficult, could be a candidate for prehabilitation with Botulinum.

Colorectal cancer (CRC) treatment is associated with a high morbidity which may result in a reduced health-related quality of life (HRQoL). The pre-operative measurement of handgrip strength (HGS) might be a tool to predict the patient's outcome after CRC surgery. The aim of this study was to evaluate the association of pre-operative HGS with the occurrence of postoperative complications and postoperative HRQoL. Stage I to III CRC patients ≥ 18 years were included at diagnosis. Demographic and clinical data as well as HGS were collected before start of treatment. HGS was classified as weak if it was below the gender-specific 25th percentile of our study population; otherwise HGS was classified as normal. The occurrence of postoperative complications within 30 days after surgery was collected from medical records. Cancer-specific HRQoL was measured 6 weeks after treatment using the EORTC QLQ-C30 and the EORTC QLQ-CR29 questionnaire. Of 295 patients who underwent surgical treatment for CRC, 67 (23%) patients had a weak HGS while 228 (77%) patients had normal HGS. 118 patients (40%) developed a postoperative complication. Complications occurred in 37% of patients with a weak HGS and in 41% of patients with a normal HGS (p = 0.47). After adjustment for age, sex, ASA, BMI and TNM, no significant associations between pre-operative HGS and the occurrence of postoperative complications and between HGS and HRQoL were found. We conclude that a single pre-operative HGS measurement was not associated with the occurrence of postoperative complications or post-treatment HRQoL in stage I-III CRC patients.

BACKGROUND: Currently, the lack of consensus on postoperative mesh-tissue adhesion scoring leads to incomparable scientific results. The aim of this study was to develop an adhesion score recognized by experts in the field of hernia surgery. METHODS: Authors of three or more previously published articles on both mesh-tissue adhesion scores and postoperative adhesions were marked as experts. They were queried on seven items using a modified Delphi method. The items concerned the utility of adhesion scoring models, the appropriateness of macroscopic and microscopic variables, the range and use of composite scores or subscores, adhesion-related complications and follow-up length. This study comprised two questionnaire-based rounds and one consensus meeting. RESULTS: The first round was completed by 23 experts (82%), the second round by 18 experts (64%). Of those 18 experts, ten were able to participate in the final consensus meeting and all approved the final proposal. From a total of 158 items, consensus was reached on 90 items. The amount of mesh surface covered with adhesions, tenacity and thickness of adhesions and organ involvement was concluded to be a minimal set of variables to be communicated separately in each future study on mesh adhesions. CONCLUSION: The MEsh Tissue Adhesion scoring system is the first consensus-based scoring system with a wide backing of renowned experts and can be used to assess mesh-related adhesions. By including this minimal set of variables in future research interstudy comparability and objectivity can be increased and eventually linked to clinically relevant outcomes.

BACKGROUND AND AIMS: To assess safety of the Exilis™ gastric electrical stimulation (GES) system and to investigate whether the settings can be adjusted for comfortable chronic use in subjects with morbid obesity. Gastric emptying and motility and meal intake were evaluated. METHOD: In a multicenter, phase 1, open prospective cohort study, 20 morbidly obese subjects (17 female, mean BMI of 40.8 ± 0.7 kg/m2) were implanted with the Exilis™ system. Amplitude of the Exilis™ system was individually set during titration visits. Subjects underwent two blinded baseline test days (GES ON vs. OFF), after which long-term, monthly follow-up continued for up to 52 weeks. RESULTS: The procedure was safe, and electrical stimulation was well tolerated and comfortable in all subjects. No significant differences in gastric emptying halftime (203 ± 16 vs. 212 ± 14 min, p > 0.05), food intake (713 ± 68 vs. 799 ± 69 kcal, p > 0.05), insulin AUC (2448 ± 347 vs. 2186 ± 204, p > 0.05), and glucose AUC (41 ± 2 vs.41 ± 2, p > 0.05) were found between GES ON and OFF. At week 4, 13, and 26, a significant (p < 0.01) reduction in weight loss was observed but not at week 52. At this time point, the mean excess weight loss (EWL) was 14.2 ± 4.5%. CONCLUSION: Gastric electrical stimulation with the Exilis™ system can be considered as safe. No significant effect on food intake, gastric emptying, or gastric motility was observed. The reduction in weight loss with Exilis™ GES was significant but short lasting. Further electrophysiological research is needed to gain more insight in optimal stimulation parameters and lead localization.

AIM: The low anterior resection syndrome (LARS) severely affects quality of life (QoL) after colorectal cancer surgery. There are no data about these complaints and the association with QoL in a reference population. The aim of this study was to assess LARS and the association with QoL in a reference population. METHODS: Six hundred patients who visited the outpatient clinic because of general or trauma surgical indications were asked to participate in this study. They received an invitation letter containing three validated questionnaires to assess LARS (assessed with the LARS score) and both general [European Organization for the Research and Treatment of Cancer (EORTC) QLQ-C30] and colorectal-specific (EORTC QLQ-CR29) QoL. RESULTS: Five hundred and one respondents could be included for the analyses. The median age at inclusion was 68 years and 47.3% were men. Major LARS was observed in 15% of patients (11.4% in men and 18.9% in women, P = 0.021). Women reported more urgency (P = 0.070) and incontinence for both flatus (P < 0.001) and stool (P = 0.063) compared to men. In univariate analyses, women reported major LARS significantly more often than men (OR 1.82; 95% CI 1.10-3.01). Patients with major LARS scored significantly worse in most QoL domains compared to patients with no/minor LARS. CONCLUSION: This is the first study demonstrating major LARS and the association with QoL in a reference population of patients without colorectal cancer. Our data can assist in the interpretation of LARS in past and future research about abdominal complaints after colorectal cancer surgery.

PURPOSE: An incisional hernia occurs frequently after a midline incision with an incidence of 12.8%. The choice in suture material used for abdominal wall closure is not straightforward and the conflicting literature focuses on clinical outcomes. This study compares a non-absorbable, slow-absorbable and fast-absorbable suture in a rat model, focusing on histological outcomes predicting better fascia healing. METHODS: 33 male Wistar rats, divided over three groups, each received two separate 1 cm incisions closed with either Prolene 4/0, PDS 4/0 or Vicryl 4/0. At 7 days and 21 days, one of the incisions was explanted. Tissue was semi-quantitatively scored regarding inflammatory cells and collagen fibres present. Using qPCR macrophage polarisation, fibroblast activity and vascularisation were evaluated. Data were analysed by Kruskal-Wallis test with Mann-Whitney U post hoc test. A p value of 0.017 was considered significant after Bonferroni correction. RESULTS: All animals recovered without complications and completed the 21 days of follow-up. The Vicryl group showed a higher presence of macrophages after 21 days in comparison with Prolene (p = 0.003) and PDS (p = 0.006) and more foreign body giant cells compared to Prolene at 7 days (p = 0.010) and PDS at 21 days (p < 0.001). qPCR showed 2.5-fold higher expression of clec10A in PDS compared to Prolene after 7 days (p = 0.007). CONCLUSIONS: The results of this study carefully support the use of PDS suture, compared to Prolene and Vicryl, in abdominal wall closure based on a favourable macrophage response. The heterogeneity and variability in the data might be explained by the spectrum of the macrophage subtype paradigm.

AIM: Low anterior resection syndrome (LARS) severely affects the quality of life (QoL) of patients after surgery for rectal cancer. There are very few studies that have investigated LARS-like symptoms and their effect on QoL after colon cancer surgery. The aim of this study was to investigate the prevalence of functional abdominal complaints and related QoL after colon cancer surgery compared with patients with similar complaints after rectal cancer surgery. METHOD: All patients who underwent colorectal cancer resections between January 2008 and December 2015, and who were free of colostomy for at least 1 year, were eligible (n = 2136). Bowel function was assessed by the LARS score, QoL by the EORTC QLQ-C30 and QLQ-CR29 questionnaires. QoL was compared between the LARS score categories and tumour height categories. RESULTS: A total of 1495 patients (70.0%) were included in the analyses, of whom 1145 had a colonic and 350 a rectal tumour. Symptoms of LARS were observed in 55% after rectal cancer resection compared with 21% after colon cancer resection. Female gender (OR 1.88, CI 1.392-2.528) and a previous diverting stoma (OR 1.84, CI 1.14-2.97) were independently associated with a higher prevalence of LARS after colon cancer surgery. Patients with LARS after colon cancer surgery performed significantly worse in most QoL domains. CONCLUSION: The results of this study highlight the presence of LARS-like symptoms after surgery for colonic cancer. Patients suffering from major LARS-like symptoms after colon resection reported the same debilitating effect on their QoL as patients with major LARS after rectal resection. This should be addressed by colorectal cancer specialists in order to adequately inform patients.

PURPOSE: Laparoscopic intraperitoneal onlay mesh in hernia repair can result in adhesions leading to intestinal obstruction and fistulation. The aim of this systematic review is to compare the effects of mesh coatings reducing the tissue-to-mesh adhesion in animal studies. METHODS: Pubmed and Embase were systematically searched. Animal experiments comparing intraperitoneally placed meshes with coatings were eligible for inclusion. Only studies with comparable follow-up, measurements, and species were included for data pooling and subsequent meta-analysis. RESULTS: A total of 131 articles met inclusion criteria, with four studies integrated into one comparison and five studies integrated into another comparison. Compared to uncoated polypropylene (PP) mesh, PP mesh coated with hyaluronic acid/carboxymethyl cellulose (HA/CMC) showed significantly reduced adhesion formation at follow-up of 4 weeks measured with adhesion score of extent (random effects model, mean difference,- 0.96, 95% CI - 1.32 to - 0.61, P < 0.001, I2 = 23%; fixed effects model, mean difference,- 0.94, 95% CI - 1.25 to - 0.63, P < 0.001, I2 = 23%). Compared to PP mesh, polyester mesh coated with collagen (PC mesh) showed no significant difference at follow-up of 4 weeks regarding percentage of adhesion-area on a mesh, using random effects model (mean difference - 11.69, 95% CI - 44.14 to 20.76, P = 0.48, I2 = 92%). However, this result differed using fixed effects model (mean difference - 25.55, 95% CI - 33.70 to - 7.40, P < 0.001, I2 = 92%). CONCLUSION: HA/CMC coating reduces adhesion formation to PP mesh effectively at a follow-up of 4 weeks, while the anti-adhesive properties of PC mesh are inclusive comparing all study data.

INTRODUCTION: Acute abdominal complaints are a frequent cause for consultation in the emergency department, with a large differential diagnosis. One cause is arcuate line herniation, but this entity is little known and rarely considered during initial analysis. The incidence of arcuate line herniation in this population is unknown. METHODS: A retrospective cohort study was performed. All patients who presented to the emergency department for surgical consultation during an 18-month period with abdominal complaints in who no diagnosis was found after analysis, and who had computed tomography imaging of the abdomen were included. CT scans were reviewed with a focus on abdominal wall pathology and correlated with clinical features. RESULTS: Eight hundred and ten patients presented with abdominal complaints, 415 of these had CT scans available for review and were included in the study. In 47 patients (11.3%), an arcuate line anomaly was found, and in 14 patients (3.4%), a frank arcuate line herniation (grades 2 or 3) was found. Retrospective correlation with clinical complaints was found in 50% of these patients. Patients with arcuate line hernia had a significantly higher BMI, and diabetes mellitus and aortic aneurysm were more prevalent in these patients. CONCLUSION: Arcuate line herniation has a higher incidence than previously thought in patients with acute abdominal complaints and should be considered when evaluating these patients.

PURPOSE: Incisional hernias after laparotomy are associated with significant morbidity and increased costs. Recent research on prevention of incisional hernia formation suggests that a laparotomy closure technique using a slowly absorbable monofilament suture with small fascial steps and bites in a continuous, single layer with a suture length to wound length (SL/WL) ratio of at least 4:1 is effective in lowering morbidity. Little is known about application of this evidence in daily practice. Therefore, a survey was performed among Dutch surgeons. METHODS: All members of the Dutch Surgical Society were invited to participate in a 24-question online survey on techniques and materials used for abdominal wall closure after midline laparotomy. Subgroup analysis was performed based on surgical subspecialty, type of hospital and experience. RESULTS: Response rate was 26% (402 respondents), representing 97% of all Dutch surgical departments. More than 90% of participants closed the abdominal wall in a single mass layer, using a slowly absorbable monofilament running suture The SL/WL ratio of >4:1 is practiced by only 35% of participants and preferred suture size was variable among participants. Risk factors for incisional hernia development were generally identified correctly but more than half of the participants were unaware of the incidence and time of occurrence of incisional hernia. Subgroup analysis found that gastrointestinal and oncologic surgeons preferred smaller diameter sutures and higher suture-length to wound-length ratios. Trauma, vascular and pediatric surgeons had lower estimates of incidence of incisional hernia than other subspecialties. Surgeons employed in academic hospitals were more likely to use small fascial steps and smaller suture sizes than their colleagues in non-academic hospitals. Correct estimates of incisional hernia incidence decreased when surgeons perform less than 10 laparotomies annually. CONCLUSION: Implementation of the latest evidence regarding closure techniques of the abdominal wall is not widespread. Only 35% of surgeons close the abdominal fascia using a suture length to wound length ratio of 4:1, which is recommended based on the latest evidence. Surgical trainees, gastrointestinal and oncological surgeons are most familiar with the recommended technique and use it in their daily practice. Efforts should be directed at improving spreading of this technique.

PURPOSE: To provide an overview of the available literature on prevention of incisional hernias after stoma reversal, with the use of prophylactic meshes. METHODS: A literature search of Pubmed, MEDLINE and EMBASE was performed. Search terms for stoma, enterostomy, mesh, prophylaxis and hernia were used. Search was updated to December 31th 2018. No time limitations were used, while English, Geman, Dutch and French were used as language restrictions. The primary outcome was the incidence of incisional hernia formation after stoma reversal. Secondary outcomes were mesh-related complications. Data on study design, sample size, patient characteristics, stoma and mesh characteristics, duration of follow-up and outcomes were extracted from the included articles. RESULTS: A number of 241 articles were identified and three studies with 536 patients were included. A prophylactic mesh was placed in 168 patients to prevent incisional hernias after stoma reversal. Follow-up ranged from 10 to 21 months. The risk of incisional hernia in case of prophylactic mesh placement was significantly lower in comparison to no mesh placement (OR 0.10, 95% CI 0.04-0.27, p < 0.001, I2 = 0%, CI 0-91.40%). No differences in surgical site infections were detected between the groups. CONCLUSIONS: The use of a prophylactic mesh seems to reduce the risk on incisional hernias after stoma reversal and therefore mesh reinforcement should be considered after stoma reversal.
