Abstract
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.

A systematic review of outcome reporting in incisional hernia surgery. BJS Open 2021; 5:6220250. [PMID: 33839746 PMCID: PMC8038267 DOI: 10.1093/bjsopen/zrab006] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 12/20/2020] [Accepted: 01/13/2021] [Indexed: 01/13/2023] Open
Abstract
Background The incidence of incisional hernia is up to 20 per cent after abdominal surgery. The management of patients with incisional hernia can be complex with an array of techniques and meshes available. Ensuring consistency in reporting outcomes across studies on incisional hernia is important and will enable appropriate interpretation, comparison and data synthesis across a range of clinical and operative treatment strategies. Methods Literature searches were performed in MEDLINE and EMBASE (from 1 January 2010 to 31 December 2019) and the Cochrane Central Register of Controlled Trials. All studies documenting clinical and patient-reported outcomes for incisional hernia were included. Results In total, 1340 studies were screened, of which 92 were included, reporting outcomes on 12 292 patients undergoing incisional hernia repair. Eight broad-based outcome domains were identified, including patient and clinical demographics, hernia-related symptoms, hernia morphology, recurrent incisional hernia, operative variables, postoperative variables, follow-up and patient-reported outcomes. Clinical outcomes such as hernia recurrence rates were reported in 80 studies (87 per cent). A total of nine different definitions for detecting hernia recurrence were identified. Patient-reported outcomes were reported in 31 studies (34 per cent), with 18 different assessment measures used. Conclusions This review demonstrates the significant heterogeneity in outcome reporting in incisional hernia studies, with significant variation in outcome assessment and definitions. This is coupled with significant under-reporting of patient-reported outcomes.

Suture fixation versus self-gripping mesh for open inguinal hernia repair: a systematic review with meta-analysis and trial sequential analysis. Surg Endosc 2020; 35:2480-2492. [PMID: 32444971 DOI: 10.1007/s00464-020-07658-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 05/15/2020] [Indexed: 01/30/2023]
Abstract
INTRODUCTION Morbidity following open inguinal hernia repair is mainly related to chronic pain. ProGrip™ is a self-gripping mesh which aims to reduce rates of chronic pain. The aim of this study is to perform an update meta-analysis to consolidate the non-superiority hypothesis in terms of postoperative pain and recurrence and perform a trial sequential analysis. METHODS Systematic review of randomised controlled trials performed according to PRISMA guidelines. Pooled odds ratios with 95% confidence intervals (CI) were calculated using the Mantel-Haenszel (M-H) method. The primary outcome measure was postoperative pain and secondary outcomes were recurrence, operative time, wound complications, length of stay, re-operation rate, and cost. Trial sequential analysis was performed. RESULTS There were 14 studies included in the quantitative analysis with 3180 patients randomised to self-gripping mesh (1585) or standard mesh (1595). At all follow-up time points, there was no significant difference in the rates of chronic pain between the self-gripping and standard mesh (risk ratio, RR 1.10, 95% confidence interval, CI 0.83-1.46). There were no significant differences in recurrence rates (RR 1.13, CI 0.84-2.04). The mean operating time was significantly shorted in the ProGrip™ mesh group (MD - 7.32 min, CI - 10.21 to - 4.44). Trial sequential analysis suggests findings are conclusive. CONCLUSION This meta-analysis has confirmed no benefit of a ProGrip™ mesh when compared to a standard sutured mesh for open inguinal hernia repair in terms of chronic pain or recurrence. No further trials are required to address this clinical question.

Abstract
BACKGROUND The aim of this study was to analyse local single-institution data and perform a systematic review of the literature to calculate precise risk estimates of rectal stump-related morbidity and mortality following subtotal colectomy in patients with inflammatory bowel disease (IBD), including Crohn's colitis, ulcerative colitis and indeterminate colitis. METHODS Institutional information systems were interrogated to obtain local patient data. A systematic review of MEDLINE and EMBASE was performed to identify relevant articles. Fixed-effects or random-effects meta-analysis of proportions was performed to calculate pooled incidence estimates, including local data. RESULTS Sixty-one patients were included locally and all had their rectal stump closed intra-abdominally. Four patients (8.3%) had a rectal stump perforation and 30-day mortality was 0. Fourteen papers were included in our review alongside local data, with a total of 1330 patients included. Pooled mortality was 1.7% (95% confidence interval, CI 1.0-2.8), pooled incidence of pelvic abscess/sepsis, stump leak and wound infection was 5.7% (95% CI 4.4-7.3), 4.9% (95% CI 3.7-6.6) and 11.3% (95% CI 7.8-16), respectively. Subcutaneous placement of the stump was associated with the highest incidence of stump leak (12.6%, 95% CI 8.3-18.6), and closure of the stump with both staples and suture was associated with the highest incidence of pelvic abscess (11.1%, 95% CI 5.8-20.3). Mortality and the incidence of wound infection were similar across stump closure techniques. There was evidence suggesting considerable heterogeneity and publication bias among studies. CONCLUSIONS This study provides estimates of morbidity associated with the rectal stump after subtotal colectomy for IBD. A closed intra-abdominal stump seems to be associated with the highest rate of pelvic abscess/sepsis. Further work in form of an international collaborative project would allow individual patient data analysis and identification of risk factors for complications.

Abstract
BACKGROUND One standard repair technique for groin hernias does not exist. The objective of this study is to perform an update meta-analysis and trial sequential analysis to investigate if there is a difference in terms of recurrence between laparoscopic and open primary unilateral uncomplicated inguinal hernia repair. METHODS The reporting methodology conforms to PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Randomised controlled trials only were included. The intervention was laparoscopic mesh repair (transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP)). The control group was Lichtenstein repair. The primary outcome was recurrence rate and secondary outcomes were acute and chronic post-operative pain, morbidity and quality of life. RESULTS This study included 12 randomised controlled trials with 3966 patients randomised to Lichtenstein repair (n = 1926) or laparoscopic repair (n = 2040). There were no significant differences in recurrence rates between the laparoscopic and open groups (odds ratio (OR) 1.14, 95% CI 0.51-2.55, p = 0.76). Laparoscopic repair was associated with reduced rate of acute pain compared to open repair (mean difference 1.19, CI - 1.86, - 0.51, p ≤ 0.0006) and reduced odds of chronic pain compared to open (OR 0.41, CI 0.30-0.56, p ≤ 0.00001). The included trials were, however, of variable methodological quality. Trial sequential analysis reported that further studies are unlikely to demonstrate a statistically significant difference between the two techniques. CONCLUSION This meta-analysis and trial sequential analysis report no difference in recurrence rates between laparoscopic and open primary unilateral inguinal hernia repairs. Rates of acute and chronic pain are significantly less in the laparoscopic group.

Short-term results after laparoscopic repair of giant hiatal hernias with pledgeted sutures: a retrospective analysis. Hernia 2019; 23:397-401. [PMID: 30684104 PMCID: PMC6456475 DOI: 10.1007/s10029-019-01890-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2018] [Accepted: 01/14/2019] [Indexed: 11/29/2022]
Abstract
Purpose This study investigates if pledgeted sutures for hiatal closure could be an alternative to mesh for the surgical treatment of large hiatal hernia. Methods Forty-one patients who underwent laparoscopic 270° Toupet fundoplication with pledgeted sutured crura between September 2014 and April 2017 were evaluated with regard to recurrence of hiatal hernia at 3 months and 1 year after surgery. Indication for pledgets was a hiatal surface area of at least 5.60 cm2, or migration of more than 1/3 of the stomach into the thorax or preoperative hernia size > 5 cm. The integrity of repair was assessed using a barium swallow test 3 months and 1 year after surgery. Results All operations could be completed laparoscopically with no intraoperative complications. Until study end no complications related to the pledgets have occurred. Forty-four of 50 patients (88.0%) completed the follow-up radiographic examination 3 months (mean 12.7 weeks) after surgery, and 37 patients (74.0%; mean 55.1 weeks) 1 year after surgery. Postoperative recurrence was diagnosed in 3/44 patients (6.8%) at 3 months, and in 4/37 patients (10.8%) at 1 year follow-up. Only one patient was symptomatic, 1 year after surgery (2.7%). All other patients with reherniations were asymptomatic at time of the study. Conclusions Utilization of pledgets to reinforce hiatal sutures seems safe and shows a quite low early recurrence rate compared to other methods. Long-term data will allow firm conclusions as to whether pledgeted sutures are an appropriate solution for the treatment of giant hiatal hernias.

Abstract
BACKGROUND To investigate the role of perioperative beta-blocker use in vascular and endovascular surgery. METHODS We performed a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards. The review protocol was registered with International Prospective Register of Systematic Reviews (registration number:CRD42016038111). We searched electronic databases to identify all randomized controlled trials and observational studies investigating outcomes of patients undergoing vascular and endovascular surgery with or without perioperative beta blockade. We used the Cochrane tool and the Newcastle-Ottawa scale to assess the risk of bias of trials and observational studies, respectively. Random-effects models were applied to calculate pooled outcome data. RESULTS We identified three randomized trials, five retrospective cohort studies, and three prospective cohort studies, enrolling a total of 32,602 patients. Our analyses indicated that perioperative use of beta-blockers did not reduce the risk of all-cause mortality [odds ratio (OR) 1.10, 95% confidence interval (CI) 0.59-2.04, P = 0.77], cardiac mortality (OR 2.62, 95% CI 0.86-8.05, P = 0.09), myocardial infarction (OR 0.89, 95% CI 0.59-1.35, P = 0.58), unstable angina (OR 1.34, 95% CI 0.41- 4.38, P = 0.63), stroke (OR 2.45, 95% CI 0.89-6.75, P = 0.08), arrhythmias (OR 0.76, 95% CI 0.41-1.43, P = 0.40), congestive heart failure (OR 1.12, 95% CI 0.77-1.63, P = 0.56), renal failure (OR 1.48, 95% CI 0.90-2.45, P = 0.13), composite cardiovascular events (OR 0.88, 95% CI 0.55-1.40, P = 0.58), rehospitalisation (OR 0.86, 95% CI 0.48-1.52, P = 0.60), and reoperation (OR 1.17, 95% CI 0.42-3.27, P = 0.77) in vascular surgery. CONCLUSIONS Beta-blockers do not improve perioperative outcomes in vascular and endovascular surgery.

What is the evidence for the use of biologic or biosynthetic meshes in abdominal wall reconstruction? Hernia 2018; 22:249-269.

Abstract
INTRODUCTION Although many surgeons have adopted the use of biologic and biosynthetic meshes in complex abdominal wall hernia repair, others have questioned the use of these products. Criticism is addressed in several review articles on the poor standard of studies reporting on the use of biologic meshes for different abdominal wall repairs. The aim of this consensus review is to conduct an evidence-based analysis of the efficacy of biologic and biosynthetic meshes in predefined clinical situations. METHODS A European working group, "BioMesh Study Group", composed of invited surgeons with a special interest in surgical meshes, formulated key questions, and forwarded them for processing in subgroups. In January 2016, a workshop was held in Berlin where the findings were presented, discussed, and voted on for consensus. Findings were set out in writing by the subgroups followed by consensus being reached. For the review, 114 studies and background analyses were used. RESULTS The cumulative data regarding biologic mesh under contaminated conditions do not support the claim that it is better than synthetic mesh. Biologic mesh use should be avoided when bridging is needed. In inguinal hernia repair biologic and biosynthetic meshes do not have a clear advantage over the synthetic meshes. For prevention of incisional or parastomal hernias, there is no evidence to support the use of biologic/biosynthetic meshes. In complex abdominal wall hernia repairs (incarcerated hernia, parastomal hernia, infected mesh, open abdomen, enterocutaneous fistula, and component separation technique), biologic and biosynthetic meshes do not provide a superior alternative to synthetic meshes. CONCLUSION The routine use of biologic and biosynthetic meshes cannot be recommended.

European Hernia Society guidelines on prevention and treatment of parastomal hernias. Hernia 2017; 22:183-198.

Abstract
BACKGROUND International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project. METHODS The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants. RESULTS End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed. CONCLUSION An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

Abstract
Background and Aims: Self-expanding metallic stents are increasingly used in the management of malignant and benign colorectal obstructions. We aimed to identify relevant predictive factors for stent failure and stent-related complications. Material and Methods: We conducted a retrospective single-center analysis of 204 consecutive patients who underwent emergency colorectal stenting procedures because of symptomatic bowel obstructions from 1996 to 2011 at the Sisters of Charity Hospital Linz, Austria. Results: A total of 204 patients (median age 74 years) with 36 (17.7%) benign and 168 (82.3%) malignant obstructions were included in the study. Technical success was achieved in 92.5% and clinical success in 86.8% of the cases. Major complications occurred in 2.9% and minor ones in 19.6%. Overall mortality during a median follow-up period of 4.3 years was 73% (149 patients). Relevant predictors of increased risk of complications were extracolonic obstruction (p = 0.001), complete obstruction (p = 0.066), and inflammatory bowel disease (p = 0.05). Stent localization at the splenic flexure, a stenosis of >8 cm in length, and the need for endoscopic guidance were associated with higher rates of technical and/or clinical stenting failure. Conclusion: Colorectal stenting is less invasive than other means of emergency treatment for large bowel obstruction; it is generally safe and effective in different types of colorectal obstruction. However, relevant rates of failure and complications were recorded and predictors could be determined.

Abstract
PURPOSE Parastomal hernias (PSHs) have been a major clinical problem. The aim of this study was to evaluate a new method of PSH repair in combination with an additional flat mesh reinforcement of the abdominal wall. METHODS In a pilot case series, seven patients suffering from complex PSHs (≥5 cm diameter and/or recurrence) underwent surgery and were treated by intraperitoneal onlay technique (IPOM) with a synthetic 3-D funnel-shaped mesh implant. The demographics, perioperative, and follow-up data are presented in this report. RESULTS The surgical strategy varied between purely laparoscopic (n = 1), laparoscopically assisted (hybrid n = 3), or open techniques (n = 3) using original or suture-reconstructed mesh devices. The funnel mesh implantations in IPOM technique were combined with attached flat meshes in the appropriate position of the abdominal wall. No procedure-related complications occurred. The mean length of hospital stay was 12 days and the mean operating time was 171 min. No recurrence of PSH or incisional hernias was observed during a mean follow-up period of 12.3 months (range from 7 to 22). CONCLUSION The use of a 3-D mesh implant has so far shown to be a promising option in the treatment of primary and recurrent PSHs. Its use proved to be reasonable in both laparoscopic and open IPOM technique. PSHs were preferably repaired using the original, unmodified implant, but when we also found it safe to incise, place and then suture the mesh around the pre-existing ostomy.

Abstract
INTRODUCTION The retrojugular approach for carotid endarterectomy (CEA) has been reported to have the advantages of shorter operative time and ease of dissection, especially in high carotid lesions. Controversial opinion exists with regard to its safety and benefits over the conventional antejugular approach. METHODS A systematic review of electronic information sources was conducted to identify studies comparing outcomes of CEA performed with the retrojugular and antejugular approach. Synthesis of summary statistics was undertaken and fixed or random effects models were applied to combine outcome data. FINDINGS A total of 6 studies reporting on a total of 740 CEAs (retrojugular approach: 333 patients; antejugular approach: 407 patients) entered our meta-analysis models. The retrojugular approach was found to be associated with a higher incidence of laryngeal nerve damage (odds ratio [OR]: 3.21, 95% confidence interval [CI]: 1.46-7.07). No significant differences in the incidence of hypoglossal or accessory nerve damage were identified between the retrojugular and antejugular approach groups (OR: 1.09 and 11.51, 95% CI: 0.31-3.80 and 0.59-225.43). Cranial nerve damage persisting during the follow-up period was similar between the groups (OR: 2.96, 95% CI: 0.79-11.13). Perioperative stroke and mortality rates did not differ in patients treated with the retrojugular or antejugular approach (OR: 1.26 and 1.28, 95% CI: 0.31-5.21 and 0.25-6.50). CONCLUSIONS Currently, there is no conclusive evidence to favour one approach over the other. Proof from a well designed randomised trial would help determine the role and benefits of the retrojugular approach in CEA.

Using the usual diagnostic tools like barium swallow examination, endoscopy, and manometry, we are able to diagnose a hiatal hernia, but it is not possible to predict the size of the hernia opening or, respectively, the size of the hiatal defect. At least a correlation can be expected if the gastroesophageal junction is endoscopically assessed in a retroflexed position, and graded according to Hill. So far, it is not possible to come to a clear conclusion how the hiatal closure during hiatal hernia repair should be performed. There is no consensus on using a mesh, and when using a mesh which type or shape should be used. Further studies including long-term results on this issue are necessary. However, it seems obvious to make the decision depending on certain conditions found during operation, and not on preoperative findings.

Abstract
Gastroesophageal reflux disease is a common clinical entity in Western societies. Its association with hiatal hernia has been well documented; however, the comparative clinical profile of patients in the presence or absence of hiatal hernia remains mostly unknown. The aim of the present study was to delineate and compare symptom, impedance, and manometric patterns of patients with and without hiatal hernia. A cumulative number of 120 patients with reflux disease were enrolled in the study. Quality of life score, demographic, symptom, manometric, and impedance data were prospectively collected. Data comparison was undertaken between patients with and without hiatal hernia. A P-value < 0.05 was considered statistically significant. Patients with hiatal hernia tended to be older than patients without hernia (52.3 vs. 48.6 years, P < 0.05), whereas quality of life scores were slightly better for the former (97.0 vs. 88.2, P= 0.005). Regurgitation occurred more frequently in patients without hiatal hernia (78.3% vs. 93.9%, P < 0.05). Otherwise, no differences were found with regard to esophageal and extraesophageal symptoms. However, lower esophageal sphincter pressures (7.7 vs. 10.0 mmHg, P= 0.007) and more frequent reflux episodes (upright, 170 vs. 134, P= 0.01; supine, 41 vs. 24, P < 0.03) were documented for patients with hiatal hernia on manometric and impedance studies. Distinct functional characteristics in patients with and without hiatal hernia may suggest a tailored therapeutic management for these diverse patient groups.

Abstract
Hiatal hernia is an underlying factor contributing to gastroesophageal reflux disease (GERD). However, it remains elusive whether the size of the esophageal hiatus has a de facto influence on the lower esophageal sphincter (LES), on the intensity of patient reflux, on GERD symptoms and on the quality of life (QoL). One hundred patients with documented chronic GERD underwent laparoscopic fundoplication. QoL was evaluated before surgery using the Gastrointestinal Quality of Life Index (GIQLI). Additionally, GERD symptoms and nonspecific gastrointestinal symptoms were documented using a standardized questionnaire (score 0-224). The size of the esophageal hiatus was measured during surgery by calculating the hiatal surface area (HSA). Correlation analysis between the preoperative QoL, GERD symptoms, esophageal manometry, multichannel intraluminal impedance monitoring data and HSA size was performed, in order to investigate whether the HSA has an influence on the patients'symptoms, GIQLI, manometry and multichannel intraluminal impedance monitoring data. Statistical significance was set at a P-value of 0.05. The HSA sizes ranged from 1.51cm(2) to 16.09cm(2) (mean 4.14cm(2) ). The preoperative GIQLI ranged from 15 points to 133 points (mean 94.37 points). Symptom scores ranged from 2 points to 192 points (mean 49.84 points). No significant influence of the HSA on GIQLI or preoperative symptoms was recorded. HSA size had a significant negative effect on LES pressure. Additionally, there was a significant positive correlation between HSA size and number of refluxes in supine position. For the rest of the evaluated data, including DeMeester score, total number of refluxes, refluxes in upright position, acid reflux events, proximal reflux events, LES length and body motility, no significant correlation was found. Although patients subjectively are not significantly affected by the size of the hiatus, it has significant effects on the LES pressure and on gastroesopageal reflux in supine position.

Circulating matrix metalloproteinases and their inhibitors in inguinal hernia and abdominal aortic aneurysm. INT ANGIOL 2011; 30:123-129.

Abstract
AIM There is evidence supporting the role of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in aortic and abdominal wall connective tissue degeneration, resulting in aneurysm and hernia formation. Furthermore, clinical association studies have demonstrated increased prevalence of abdominal wall hernias in patients with aortic aneurysms. Our objective was to estimate the levels of MMPs and TIMPs in the blood of patients with aortic aneurysm and inguinal hernia, in order to investigate whether there is potential pathogenic linkage of impaired collagen metabolism. METHODS Plasma concentrations of MMP-9, MMP-2, TIMP-1 and TIMP-2 were quantified using ELISA in 33 male patients with abdominal aortic aneurysm and 91 male patients with inguinal hernia. They were consecutive patients undergoing repair during the study period. The same substances were measured in 35 healthy male controls. RESULTS MMP-9 and MMP-2 concentrations were lower in the plasma of patients with inguinal hernia and abdominal aortic aneurysm than controls, with hernia patients having the lowest circulating levels. The levels of TIMP-2 were significantly elevated in patients with inguinal hernia and significantly reduced in patients with aortic aneurysm, whereas opposite correlations were found for circulating TIMP-1. CONCLUSION Different patterns of circulating MMP and TIMP levels were found in patients with aneurysm and hernia compared with controls. Underlying pathogenic processes implicating MMPs and TIMPs in connective tissue metabolism are expressed by differing plasma levels in the two disease states. Further research including combined plasma and tissue analyses is required to further investigate potential common pathogenesis of these diseases.

Abstract
Surgical treatment of abdominal wall hernia has been based for many decades on observational evidence, as the disease physiopathology was ambiguous. The long-standing hypothesis of abnormal collagen metabolism as a causative factor of hernia disease seems to become substantiated by modern investigations, demonstrating a link between abnormal matrix metalloproteinase (MMP) expression and abdominal wall hernia. Current evidence suggests a strong correlation between MMP-2 and direct inguinal hernia, while the role of this MMP in indirect, incisional and recurrent hernias has not been completely elucidated yet. Furthermore, MMP-1 and MMP-13 seem to be implicated in the physiopathology of recurrent hernia, while limited data link MMP-1 also with incisional hernia formation. Despite the importance of MMP-9 in wound healing mechanisms, its role in hernia pathogenesis has not been adequately investigated. Future research is expected to decipher the complex physiopathological mechanisms of hernia development and provide a basis for potential therapeutic applications.

Abstract
BACKGROUND Remote endarterectomy is a minimally invasive procedure which combines open and endovascular surgery for the treatment of long segment superficial femoral artery (SFA) occlusive disease. We conducted a systematic review of the medical literature to analyze the indications, technical limitations and the outcome of remote SFA endarterectomy (RSFAE). METHODS The English literature was searched using the MEDLINE electronic database up to February 2008. We considered studies comprising at least 10 patients treated with RSFAE and reporting on the primary and/or secondary patency rates. Average primary and secondary patency rates were obtained by weighting the data of each study by the number of limbs treated. RESULTS Our search identified 19 retrospective or prospective case series; no randomized controlled trials comparing RSFAE with another treatment modality were identified. The average technical success rate was 94% and the procedure-related complication rate was 14.7%. The weighted mean cumulative primary patency rates were 60%, 57% and 35% at 1, 2 and 5 years, respectively. The weighted mean assisted primary patency rates were 75%, 77% and 50% at 1, 2 and 5 years, respectively. The weighted mean secondary patency rates were 88% and 62% at 1 and 2 years, respectively. CONCLUSIONS RSFAE has acceptable short-, medium- and long-term results but patients should undergo intensive surveillance postoperatively. Randomized controlled trials are needed to assess the durability of this procedure as compared to conventional open bypass surgery.
