Comparison between the open and the laparoscopic approach in the primary ventral hernia repair: a systematic review and meta-analysis. Langenbecks Arch Surg 2024; 409:52. [PMID: 38307999 PMCID: PMC10837225 DOI: 10.1007/s00423-024-03241-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 01/22/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND Ventral hernia repair underwent various developments in the previous decade. Laparoscopic primary ventral hernia repair may be an alternative to open repair since it prevents large abdominal incisions. However, whether laparoscopy improves clinical outcomes has not been systematically assessed. OBJECTIVES The aim is to compare the clinical outcomes of the laparoscopic versus open approach of primary ventral hernias. METHODS A systematic search of MEDLINE (PubMed), Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted in February 2023. All randomized controlled trials comparing laparoscopy with the open approach in patients with a primary ventral hernia were included. A fixed-effects meta-analysis of risk ratios was performed for hernia recurrence, local infection, wound dehiscence, and local seroma. Meta-analysis for weighted mean differences was performed for postoperative pain, duration of surgery, length of hospital stay, and time until return to work. RESULTS Nine studies were included in the systematic review and meta-analysis. The overall hernia recurrence was twice less likely to occur in laparoscopy (RR = 0.49; 95%CI = 0.32-0.74; p < 0.001; I2 = 29%). Local infection (RR = 0.30; 95%CI = 0.19-0.49; p < 0.001; I2 = 0%), wound dehiscence (RR = 0.08; 95%CI = 0.02-0.32; p < 0.001; I2 = 0%), and local seroma (RR = 0.34; 95%CI = 0.19-0.59; p < 0.001; I2 = 14%) were also significantly less likely in patients undergoing laparoscopy. Severe heterogeneity was obtained when pooling data on postoperative pain, duration of surgery, length of hospital stay, and time until return to work. CONCLUSION The results of available studies are controversial and have a high risk of bias, small sample sizes, and no well-defined protocols. However, the laparoscopic approach seems associated with a lower frequency of hernia recurrence, local infection, wound dehiscence, and local seroma.

Abstract
OBJECTIVE To assess prevalence of hernia recurrence, surgical site infection (SSI), seroma, serious complications, and mortality after retro-rectus repair. SUMMARY BACKGROUND DATA Ventral abdominal wall hernia is a common problem, tied to increasing frailty and obesity of patients undergoing surgery. For non-complex ventral hernia, retro-rectus (Rives-Stoppa) repair is considered the gold standard treatment. Level-1 evidence confirming this presumed superiority is lacking. METHODS Five databases were searched for studies reporting on retro-rectus repair. Single-armed and comparative randomized and non-randomized studies were included. Outcomes were pooled with mixed-effects, inverse variance or random-effects models. RESULTS Ninety-three studies representing 12440 patients undergoing retro-rectus repair were included. Pooled hernia recurrence was estimated at 3.2% (95%CI: 2.2-4.2%, n = 11049) after minimally 12 months and 4.1%, (95%CI: 2.9-5.5%, n = 3830) after minimally 24 months. Incidences of SSI and seroma were estimated at respectively 5.2% (95%CI: 4.2-6.4%, n = 4891) and 5.5% (95%CI: 4.4-6.8%, n = 3650). Retro-rectus repair was associated with lower recurrence rates compared to onlay repair (OR: 0.27, 95%CI: 0.15-0.51, p < 0.001) and equal recurrence rates compared to intraperitoneal onlay (IPOM) repair (OR: 0.92, 95%CI: 0.75-1.12, p = 0.400). Retro-rectus repair was associated with more SSI than IPOM repair (OR: 1.8, 95%CI: 1.03-3.14, p = 0.038). Minimally invasive retro-rectus repair displayed low rates of recurrence (1.3%, 95%CI: 0.7-2.3%, n = 849) and SSI (1.5%, 95%CI: 0.8-2.8%, n = 982), albeit based on non-randomized studies. CONCLUSIONS Retro-rectus (Rives-Stoppa) repair results in excellent outcomes, superior or similar to other techniques for all outcomes except surgical site infection. The latter rarely occurred, yet less frequently after IPOM repair, which is usually performed by laparoscopy.

Abstract
OBJECTIVE Abdominal entry at the time of laparoscopy is a critical step with a risk of injury to underlying viscera owing to bowel adhesions. Ultrasound can be used as a preoperative tool to assess the slide of viscera underneath the abdominal wall to detect adhesion-free areas. The objective of this systematic review and meta-analysis was to determine the diagnostic accuracy of preoperative visceral slide assessment with ultrasound to detect intra-abdominal adhesions, compared with the gold standard of intraoperative findings. DATA SOURCES Using Cochrane, Medline PubMed, Embase, and Google Scholar electronic databases, 3737 articles were screened in April 2020 using a query that included variations of "adhesions" and "ultrasound." Reference lists of relevant articles were searched for further articles. METHODS OF STUDY SELECTION Prospective and cross-sectional studies in English that included patients at risk for intra-abdominal adhesions who underwent preoperative ultrasound visceral slide assessment and subsequent intraoperative assessment of adhesions were selected. Two reviewers independently selected 25 articles, extracted data, and assessed bias using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. TABULATION, INTEGRATION, AND RESULTS Twenty-five articles reported on 1609 patients and 5812 assessed abdominal areas, with considerable heterogeneity of described abdominal areas and degrees of adhesions. Meta-analysis was performed for 21 studies. The periumbilical area was assessed specifically for bowel adhesions in 890 patients in 12 studies, with a 12.0% bowel adhesion rate. Ultrasound assessment for periumbilical bowel adhesions had a combined sensitivity of 95.9% (95% confidence interval, 82.7%-99.1%), specificity of 93.1% (85.1%-96.9%), positive predictive value of 60.4% (44.2%-74.7%), and negative predictive value of 99.2% (97.9%-99.7%) with low heterogeneity (I2 = 16%). CONCLUSION Visceral slide assessment with ultrasound has a high negative predictive value for the absence of periumbilical bowel adhesions in patients at risk for adhesions and can function as a useful tool to detect adhesion-free areas to allow for safe laparoscopic entry.

Abstract
Biomaterials and their applications are perhaps among the most dynamic areas of research within the field of biomedicine. Any advance in this topic translates to an improved quality of life for recipient patients. One application of a biomaterial is the repair of an abdominal wall defect whether congenital or acquired. In the great majority of cases requiring surgery, the defect takes the form of a hernia. Over the past few years, biomaterials designed with this purpose in mind have been gradually evolving in parallel with new developments in the different surgical techniques. In consequence, the classic polymer prosthetic materials have been the starting point for structural modifications or new prototypes that have always strived to accommodate patients’ needs. This evolving process has pursued both improvements in the wound repair process depending on the implant interface in the host and in the material’s mechanical properties at the repair site. This last factor is important considering that this site—the abdominal wall—is a dynamic structure subjected to considerable mechanical demands. This review aims to provide a narrative overview of the different biomaterials that have been gradually introduced over the years, along with their modifications as new surgical techniques have unfolded.

Abstract
Background: Infected hernia mesh is a cause of post-operative morbidity. Nitric oxide (NO) plays a key role in the endogenous immune response to infection. We sought to study the efficacy of a NO-releasing mesh against methicillin-resistant Staphylococcus aureus (MRSA). We hypothesized that a NO-releasing polyester mesh would decrease MRSA colonization and proliferation. Materials and Methods: A composite polyester mesh functionalized with N-diazeniumdiolate silica nanoparticles was synthesized and characterized. N-diazeniumdiolate silica parietex composite (NOSi) was inoculated with 104,106, or 108 colony forming units (CFUs) of MRSA and a dose response was quantified in a soy tryptic broth assay. Utilizing a rat model of contaminated hernia repair, implanted mesh was inoculated with MRSA, recovered, and CFUs were quantified. Clinical metrics of erythema, mesh contracture, and adhesion severity were then characterized. Results: Methicillin-resistant Staphylococcus aureus CFUs demonstrated a dose-dependent response to NOSi in vitro. In vivo, quantified CFUs showed a dose-dependent response to NOSi-PCO. Treated rats had fewer severe adhesions, less erythema, and reduced mesh contracture. Conclusions: We demonstrate the efficacy of a NO-releasing mesh to treat MRSA in vitro and in vivo. Creation of a novel class of antimicrobial prosthetics offers new strategies for reconstructing contaminated abdominal wall defects and other procedures that benefit from deploying synthetic prostheses in contaminated environments.

Abstract
BACKGROUND When using a prosthetic material in hernia repair, the behaviour of the mesh at the peritoneal interface is especially important for implant success. Biomaterials developed for their intraperitoneal placement are known as composites and are made up of two different-structure materials, one is responsible for good integration within host tissue and the other is responsible to make contact with the viscera. This study examines the behaviour at the peritoneal level of two composites, the fully degradable Phasix-ST® and the partially degradable Symbotex®. A polypropylene mesh (Optilene®) served as control. METHODS Sequential laparoscopy from 3 to 90 days, in a preclinical model in the New Zealand white rabbit, allowed monitoring adhesion formation. Morphological studies were performed to analyse the neoperitoneum formed in the repair process. Total macrophages were identified by immunohistochemical labelling. To identify the different macrophage phenotypes, complementary DNAs were amplified by qRT-PCR using specific primers for M1 (TNF-α/CXCL9) and M2 (MRC1/IL-10) macrophages. RESULTS The percentage of firm and integrated adhesions remained very high in the control group over time. Both composites showed a significant decrease in adhesions at all study times and in qualitative terms were mainly loose. Significant differences were also observed from 7 days onwards between the two composites, increasing the values in Phasix over time. Neoperitoneum thickness for Phasix was significantly greater than those of the other meshes, showing mature and organized neoformed connective tissue. Immunohistochemically, a significantly higher percentage of macrophages was observed in Symbotex. mRNA expression levels for the M2 repair-type macrophages were highest for Phasix but significant differences only emerged for IL-10. CONCLUSIONS Fewer adhesions formed to the Symbotex than Phasix implants. Ninety days after implant, total macrophage counts were significantly higher for Symbotex, yet Phasix showed the greater expression of M2 markers related to the tissue repair process.

Abstract
BACKGROUND Intra-abdominal adhesions after surgery are highly prevalent. Adhesions implicate complications during subsequent surgery and can cause chronic abdominal pain. The objective of this review was to investigate the usefulness of non-invasive diagnostic methods for detection of adhesions. METHODS We searched the electronic databases: MEDLINE, Embase, and The Cochrane Central Register of Controlled Trials for studies investigating the use of non-invasive diagnostic imaging techniques for detecting adhesions. Main outcome was the sensitivity and specificity of each technique. We used the Quality Assessment of Diagnostic Accuracy studies tool to assess bias. RESULTS In total, 25 studies were included: 18 using ultrasound (US), 5 using magnetic resonance imaging (MRI), 1 using computed tomography (CT), and 1 using both US and MRI. A total of 2195 patients were included. Overall accuracy ranged between 76 and 100% for US studies and between 79 and 90% for MRI and was 66% for CT. Sensitivity ranged between 21 and 100% for US and between 22 and 93% for MRI and was 61% for CT. Specificity was 32-100% for US, 25-93% for MRI, and 63% for CT. Bias analysis revealed that in most studies, investigators were blinded to the reference standard but not to the index test and 11 of 25 studies had a high risk of selection bias. CONCLUSIONS Currently, abdominal US can be used to determine the presence of adhesions between bowel and the abdominal wall. MRI is also an accurate diagnostic modality and can in addition visualize adhesions between viscera, however, with a tendency to over diagnose adhesions. There is insufficient evidence to support CT as a diagnostic modality for adhesions.

Abstract
Background This study assessed clinical outcomes, including safety and recurrence, from the two-year follow-up of patients who underwent open ventral primary hernia repair with the use of the Parietex™ Composite Ventral Patch (PCO-VP). Methods A prospective single-arm, multicenter study of 126 patients undergoing open ventral hernia repair for umbilical and epigastric hernias with the PCO-VP was performed. Results One hundred twenty-six subjects (110 with umbilical hernia and 16 with epigastric hernia) with a mean hernia diameter of 1.8 cm (0.4–4.0) were treated with PCO-VP. One hundred subjects completed the two-year study. Cumulative hernia recurrence was 3.0% (3/101; 95%CI: 0.0–6.3%) within 24 months. Median Numeric Rating Scale pain scores improved from 2 [0–10] at baseline to 0 [0–3] at 1 month (P < 0.001) and remained low at 24 months 0 [0–6] (P < 0.001). 99% (102/103) of the patients were satisfied with their repair at 24 months postoperative. Conclusions The use of PCO-VP to repair primary umbilical and epigastric defects yielded a low recurrence rate, low postoperative and chronic pain, and high satisfaction ratings, confirming that PCO-VP is effective for small ventral hernia repair in the two-year term after implantation. Trial registration The study was registered publically at clinicaltrials.gov (NCT01848184 registered May 7, 2013).

Abstract
Purpose This study examined patient-related outcome measures (PROMs) after repair of ventral primary or incisional hernias using Symbotex™ composite mesh (SCM), a novel three-dimensional collagen-coated monofilament polyester textile. Methods Pre-operative, peri-operative, and post-operative data were obtained from the French “Club Hernie” registry with 12- and 24-month follow-up. Results One-hundred consecutive patients (mean age 62.0 ± 13.7; 51% female) underwent repair of 105 hernias: primary (39/105, 37.1%, defect area 5.2 ± 5.6 cm2) and incisional (66/105, 62.9%, 31.9 ± 38.7.8 cm2). The mean BMI was 29.7 (± 5.6 kg/m2). American Society of Anesthesiologists classifications were I 39.4%, II 37.4% and III 23.2%. 75% had risk factors for healing and/or dissection. Of 38 primary repairs, 37 were completed laparoscopically (combined approach n = 1), and of 62 incisional hernia repairs, 40 were completed laparoscopically, and 20 by open repair (combined approach n = 2). Laparoscopic was quicker than open repair (36.2 ± 23.5 min vs. 67.4 ± 25.8, p < 0001). Before surgery, 86.3% of hernias were reported to cause discomfort/pain or dysesthesia. At 24 months (93 of 100 patients), 91 (97.8%) reported no lump and 81 (87.1%) no pain or discomfort. Of 91 patients, 86 (94.5%) rated their repair “good” or “excellent.” There were nine non-serious, surgeon-detected adverse events (ileus, n = 3; seroma, n = 6) and one hernia recurrence (6–12 months). Conclusions Compared to baseline, open and laparoscopic surgery improved PROMs 24 months after primary and incisional hernia repair. Minimal complications and recurrence support the long-term efficacy of SCM.

Abstract
Aim:
The SymCHro study objective is to assess patient outcomes and surgeon satisfaction following ventral hernia repair with a three-dimensional (3D) monofilament polyester mesh (Symbotex composite mesh) that contains an absorbable collagen barrier on 1 side to minimize tissue attachment.
Methods:
SymCHro is a multicenter observational study of 100 consecutive patients in the French Club Hernie registry who underwent primary and incisional ventral hernia repair with a Symbotex composite mesh. The primary objective is to assess recurrences and complications within 2 years of repair. This analysis reports 1-year results from the ongoing study.
Results:
A total of 105 hernias (37.1% primary, 62.9% incisional) in 100 patients were repaired by open or laparoscopic surgery. The patient follow-up rate at 1 year was 94%. A total of 6 (6.0%) low-grade seromas; 3 (3.0%) cases of low-grade transitory ileus; and 1 (1.0%) recurrence, which was asymptomatic but was repaired, occurred within 1-year follow-up. No serious adverse events were reported. All surgeons responded as satisfied with mesh flexibility and ease of insertion. Relative to baseline, patient pain reduced significantly at day 1 through month 3 postoperatively. At 1 year, 88.3% (83/94) patients assessed the hernia operation results as “good” or “excellent.”
Conclusion:
At this 1-year analysis, 94% of patients were followed up and experienced minimal pain and low complication rates, suggesting that Symbotex composite mesh provides an effective and safe repair for primary and incisional ventral hernias.

Abstract
Injury to the serosa through injurious agents such as radiation, surgery, infection and disease results in the loss of the protective surface mesothelium and often leads to fibrous adhesion formation. Mechanisms that increase the rate of mesothialisation are therefore actively being investigated in order to reduce the formation of adhesions. These include intraperitoneal delivery of cultured mesothelial cells as well as administration of factors that are known to increase mesothelial proliferation and migration. An exciting alternative that has only recently received attention, is the possible role of mesothelial progenitor cells in the repair and regeneration of denuded serosal areas. Accumulating evidence suggests that such a population exists and under certain conditions is able to form a number of defined cell types indicating a degree of plasticity. Such properties may explain the extensive use of mesothelial cells in various tissue engineering applications including the development of vascular conduits and peripheral nerve replacements. It is likely that with the rapid explosion in the fields of tissue engineering and regenerative medicine, a greater understanding of the potential of mesothelial progenitor cells to repair, replace and possibly regenerate damaged or defective tissue will be uncovered.

Abstract
Purpose This study assessed the recurrence rate and other safety and efficacy parameters following ventral hernia repair with a polyester composite prosthesis (Parietex™ Composite Ventral Patch [PCO-VP]). Patients and methods A single-arm, multicenter prospective study of 126 patients undergoing open ventral hernia repair with the PCO-VP was performed. Patient outcomes were assessed at discharge and at 10 days, 1, 6, 12, and 24 months postoperative. Results All patients had hernioplasty for umbilical (n = 110, 87.3%) or epigastric hernia (n = 16, 12.7%). Mean hernia diameter was 1.8 ± 0.8 cm. Mean operative time was 36.2 ±15.6 minutes, with a mean mesh positioning time of 8.1 ± 3.4 minutes. Surgeons reported satisfaction with mesh ease of use in 95% of surgeries. The cumulative hernia recurrence rate at 1 year was 2.8% (3/106). Numeric Rating Scale (NRS) pain scores showed improvement from 2.1 ± 2.0 at preoperative baseline to 0.5 ± 0.7 at 1 month postoperative (P < 0.001), and this low pain level was maintained at 12 months postsurgery (P < 0.001). The mean global Carolina’s Comfort Scale® (CCS) score improved postoperatively from 3.8 ± 6.2 at 1 month to 1.6 ± 3.5 at 6 months (P < 0.001). One patient was unsatisfied with the procedure. Conclusion This 1-year interim analysis using PCO-VP for primary umbilical and epigastric defects shows promising results in terms of mesh ease of use, postoperative pain, and patient satisfaction. Recurrence rate is low, but, as laparoscopic evaluation shows a need for patch repositioning in some cases, an accurate surgical technique remains of utmost importance.

Abstract
BACKGROUND Given concern for hernia mesh infection, surgeons often use biologic mesh which may provide reduced risk of infection but at the cost of decreased repair durability. We evaluated mesh coating to provide sustained release of antibiotics to prevent prosthetic mesh infection and also allow a durable repair. MATERIALS AND METHODS Cyclodextrin-based polymer was crosslinked onto multifilament polyester mesh and loaded with vancomycin (1.75 mg/cm2). Pigs received modified meshes (n = 6) or normal, untreated meshes (n = 4), which were implanted into acute 10 × 5 cm ventral hernia, then directly inoculated with 106 colony-forming unit (CFU) of methicillin-resistant Staphylococcus aureus (MRSA). These were compared to animals receiving normal, uninfected mesh. All mesh was secured in an underlay bridge manner, and after 30 d, the abdominal wall was removed for quantitative bacterial culture and biomechanical analysis. RESULTS All animals survived 30 d. All six animals with coated mesh cleared MRSA infection. The four control animals did not clear MRSA (P = 0.005). Quantitative bacterial load was higher in standard mesh versus drug-delivery mesh group (2.34 × 104versus 80.9 CFU/gm). These data were log10-transformed and analyzed by Welch's t-test (P = 0.001). Minimum number of CFUs detectable by assay (300) was used instead of zero. Biomechanical analysis of controls (1.82 N/mm infected; 1.71 N/mm uninfected) showed no difference to the modified meshes (1.31 N/mm) in tissue integration (P = 0.15). CONCLUSIONS We successfully prevented synthetic mesh infection in a pig model using a cyclodextrin-based polymer to locally deliver vancomycin to the hernia repair site and clearing antibiotic-resistant bacteria. Polymer coating did not impact the strength of the hernia repair.

Abstract
INTRODUCTION Laparoscopic incisional and ventral hernia repair (LIVHR) is widely accepted and safe but the type of mesh used is still debated. We retrospectively compared postoperative outcomes with two different meshes commonly used in LIVHR. METHODS This is a retrospective study of patients who underwent incisional hernia repair between January 2008 and December 2010. Two meshes were used: Parietex™ Composite (Covidien, New Haven, CT, USA) and the DynaMesh®-IPOM (FEG Textiltechnik mbH, Aachen, Germany). The two groups were compared with respect to recurrence rates, incidence of seroma and intestinal obstruction. RESULTS Among the 88 patients who underwent LIVHR, 75 patients (85.2%) presented with primary incisional hernia, 10 (11.4%) presented with a first recurrence and 3 (3.4%) presented with a second recurrence. Median follow-up was 53.6 months (range 40-61 months). 12.9% of patients had recurrence in the Parietex™ Composite mesh group (n=62) in comparison to 3.8% in the DynaMesh®-IPOM mesh group (n=26; P=0.20). DynaMesh®-IPOM was associated with a significantly higher incidence of intestinal obstruction secondary to adhesions (11.5% vs. 0%, P=0.006) and lower incidence of seroma and haematoma formation compared to Parietex™ composite mesh group (0% vs. 6.4% of patients; P=0.185). CONCLUSIONS LIVHR is a safe and feasible technique. Dynamesh®-IPOM is associated with a significantly higher incidence of adhesion related bowel obstruction, albeit with a lower incidence of recurrence, seroma and haematoma formation compared with Parietex™ Composite mesh. However, there is a need for further well-designed, multicentre randomised controlled studies to investigate the use of these meshes.

Abstract
INTRODUCTION Intraperitoneal onlay mesh repair is a current technique for laparoscopic repair of ventral and incisional hernias. However, the placement of synthetic mesh intraperitoneally may potentially lead to mesh-induced complications such as adhesive intestinal obstruction, enterocutaneous fistula, or even mesh erosion into organs. Inspired by the concept of laparoscopic inguinal hernia repair, we developed a novel technique: preperitoneal onlay mesh repair (PPOM). This involves placing the mesh in the preperitoneal plane to help eliminate mesh-induced complications. MATERIAL AND SURGICAL TECHNIQUE Our first case of PPOM was performed on a 54-year-old woman who developed a complex incisional hernia after multiple abdominal operations. The total size of the hernia defect was 8 × 13 cm. The peritoneal flap was carefully created with synthetic mesh placed on the preperitoneal plane, and then it was completely closed with sutures. The patient had an uneventful recovery except for a small seroma. DISCUSSION We herein report the first case of incisional hernia successfully treated by this novel technique, PPOM. We explain the reasons to perform PPOM, the advantages it offers, and why we named this novel technique "PPOM."

Abstract
Background: Incisional hernias and incisional hernia repair can be a significant challenge for both surgeon and patient. Despite the growing amount of literature describing various methods of surgical techniques, little has been published the natural course of an incisional hernia and regarding indications for incisional hernia repair. Methods: An internet database search was performed to identify articles describing symptoms presented by patients and indications for incisional hernia repair. Results: Various symptoms and indications regarding incisional hernia repair and the natural course of an incisional hernia are mentioned in the literature. Nevertheless, published data accurately describing these symptoms and indications are rare. Conclusion: A prospective trial monitoring incisional hernias as well as comparing conservative treatment with repair should be performed.

Abstract
Laparoscopic-assisted ventral hernia repair (LAVHR) with mesh is well established as the preferred technique for hernia repair. We sought to determine whether primary fascial closure and/or overlap of the mesh reduced recurrence and/or complications. We conducted a retrospective review on 57 LAVHR patients using polyester composite mesh between August 2010 and July 2013. They were divided into mesh-only (nonclosure) and primary fascial closure with mesh (closure) groups. Patient demographics, prior surgical history, mesh overlap, complications, and recurrence rates were compared. Thirty-nine (68%) of 57 patients were in the closure group and 18 (32%) in the nonclosure group. Mean defect sizes were 15.5 and 22.5 cm2, respectively. Participants were followed for a mean of 1.3 years [standard deviation (SD) = 0.7]. Recurrence rates were 2/39 (5.1%) in the closure group and 1/18 (5.6%) in the nonclosure group ( P = 0.947). There were no major postoperative complications in the nonclosure group. The closure group experienced four (10.3%) complications. This was not a statistically significant difference ( P = 0.159). The median mesh-to-hernia ratio for all repairs was 15.2 (surface area) and 3.9 (diameter). Median length of stay was 14.5 hours (1.7–99.3) for patients with nonclosure and 11.9 hours (6.9–90.3 hours) for patients with closure ( P = 0.625). In conclusion, this is one of the largest series of LAVHR exclusively using polyester dual-sided mesh. Our recurrence rate was about 5 per cent. Significant mesh overlap is needed to achieve such low recurrence rates. Primary closure of hernias seems less important than adequate mesh overlap in preventing recurrence after LAVHR.

Abstract
UNLABELLED The aim of this study was to define the possibility of using a collagen substance CollGARA as a protective barrier between the polypropylene mesh implant and abdominal organs. The drug is a sterile bioabsorbable membrane consisting of refolded equine collagen. Indications--use as barrier separating adjoining tissues and organs in the areas of the abdominal cavity, where the formation of adhesions. MATERIALS AND METHODS Were performed 10 operations in patients with ventral hernias with different localization. 8 patients had postoperative hernia in 2--linea alba hernia. 8 patients were operated open, 2--laparoscopically. After intra-abdominal hernia repair was performed plastic mesh implant, delimiting it from the abdominal cavity membrane CollGARA. Serious complications from the abdominal cavity and the surgical wound wasnt observed. RESULTS The first experience with intra-abdominal plastic polypropylene mesh implant coated with collagen plate indicates the possibility of applying this method in the future.

Abstract
PURPOSE Novel composite meshes routinely used in laparoscopic hernia repair reportedly lead to fewer and less dense visceral adhesions and may provide a viable alternative in thoracic surgery as well. METHODS A total of 15 adult domestic pigs underwent full thickness chest wall resection and reconstruction with Parietene (polypropylene composite; PTE, n = 5), Parietex (polyester composite; PTX, n = 5) or Bard (purely polypropylene, n = 5) mesh. After an observation period of 90 days all animals were sacrificed, intrathoracic adhesions classified via thoracoscopy (VATS), meshes explanted and peak peal strength required for lung/mesh separation recorded. RESULTS Adhesions assessed through VATS-exploration were strongest in the PTX-Group while PTE and BM showed comparable results. Tensiometric analyses of peak peal strength confirmed lower values in BM than for PTE and PTX. Both composite materials showed good overall bioincorporation with post-surgical perigraft-fibrosis being strongest in BM. CONCLUSION We consider composite grafts a suitable alternative for chest wall reconstruction. They are characterized by good overall biointegration and limited perigraft-fibrosis, thus potentially facilitating redo-procedures, even though a hydrophilic coating per se does not appear to prevent intrathoracic adhesion formation.

Abstract
BACKGROUND Mesh implantation during abdominal wall reconstruction decreases rates of ventral hernia recurrence and has become the dominant method of repair. The authors provide a comprehensive comparison of surgical outcomes and complications by location of mesh placement following ventral hernia repair with onlay, interposition, retrorectus, or underlay mesh. METHODS A systematic search of the English literature published from 1996 to 2012 in the PubMed, MEDLINE, and Cochrane library databases was conducted to identify patients who underwent abdominal wall reconstruction using either prosthetic or biological mesh for ventral hernia repair. Demographic information was obtained from each study. RESULTS Sixty-two relevant articles were included with 5824 patients treated with mesh repair of a ventral hernia between 1996 and 2012. Mesh position included onlay (19.6 percent), underlay (60.7 percent), interposition (6.4 percent), and retrorectus (12.4 percent). Prosthetic mesh was used in 80 percent of repairs and biological mesh in 20 percent. The weighted mean incidences of early events were as follows: wound complications, 19 percent; wound infections, 8 percent; seroma or hematoma formation, 11 percent; and reoperation, 10 percent. The weighted mean incidences of late complications included 8 percent for hernia recurrence and 2 percent for mesh explantation. Recurrence rates were highest for onlay (17 percent) or interposition (17 percent) reinforcement. The infection rate was also highest in the interposition cohort (25 percent). Seroma rates were lowest following a retrorectus repair (4 percent). CONCLUSIONS Mesh reinforcement of a ventral hernia repair is safe and efficacious, but the location of the reinforcement appears to influence outcomes. Underlay or retrorectus mesh placement is associated with lower recurrence rates.

Abstract
Introduction Composite biomaterials designed for the repair of abdominal wall defects are composed of a mesh component and a laminar barrier in contact with the visceral peritoneum. This study assesses the behaviour of a new composite mesh by comparing it with two latest-generation composites currently used in clinical practice. Methods Defects (7x5cm) created in the anterior abdominal wall of New Zealand White rabbits were repaired using a polypropylene mesh and the composites: PhysiomeshTM; VentralightTM and a new composite mesh with a three-dimensional macroporous polyester structure and an oxidized collagen/chitosan barrier. Animals were sacrificed on days 14 and 90 postimplant. Specimens were processed to determine host tissue incorporation, gene/protein expression of neo-collagens (RT-PCR/immunofluorescence), macrophage response (RAM-11-immunolabelling) and biomechanical resistance. On postoperative days 7/14, each animal was examined laparoscopically to quantify adhesions between the visceral peritoneum and implant. Results The new composite mesh showed the lowest incidence of seroma in the short term. At each time point, the mesh surface covered with adhesions was greater in controls than composites. By day 14, the implants were fully infiltrated by a loose connective tissue that became denser over time. At 90 days, the peritoneal mesh surface was lined with a stable mesothelium. The new composite mesh induced more rapid tissue maturation than PhysiomeshTM, giving rise to a neoformed tissue containing more type I collagen. In VentralightTM the macrophage reaction was intense and significantly greater than the other composites at both follow-up times. Tensile strengths were similar for each biomaterial. Conclusions All composites showed optimal peritoneal behaviour, inducing good peritoneal regeneration and scarce postoperative adhesion formation. A greater foreign body reaction was observed for VentralightTM. All composites induced good collagen deposition accompanied by optimal tensile strength. The three-dimensional macroporous structure of the new composite mesh may promote rapid tissue regeneration within the mesh.

Abstract
INTRODUCTION Formation of adhesions after laparoscopic hernia repair using the intra-peritoneal onlay mesh (IPOM) procedure can lead to intestinal obstruction or mesh erosion into intestinal lumen. The aims of this study included: measurement of adhesion formation with Dynamesh IPOM after laparoscopic intraperitoneal implantation, and assessment of the occurrence of isolated adhesions at the fastening sites of slowly absorbable sutures. MATERIAL AND METHODS Twelve healthy pigs underwent laparoscopic implantation of 2 Dynamesh IPOM mesh fragments each, one was fastened with PDSII, and the other with Maxon sutures. An assessment of adhesion formation was carried out after 6 weeks and included an evaluation of surface area, hardness according to the Zhulke scale, and index values. The occurrence of isolated adhesions at slowly absorbable suture fixation points was also analyzed. RESULTS Adhesions were noted in 83.3% of Dynamesh IPOM meshes. Adhesions covered on average 37.7% of the mesh surface with mean hardness 1.46 and index value 78.8. In groups fixed with PDS in comparison to Maxon sutures adhesions covered mean 31.6% vs. 42.5% (p = 0.62) of the mesh surface, mean hardness was 1.67 vs.1.25 (p = 0.34) and index 85.42 vs. 72.02 (p = 0.95). CONCLUSIONS The Dynamesh IPOM mesh, in spite of its anti-adhesive layer of PVDF, does not prevent the formation of adhesions. Adhesion hardness, surface area, and index values of the Dynamesh IPOM mesh are close to the mean values of these parameters for other commercially available 2-layer meshes. Slowly absorbable sutures used for fastening did not increase the risk of adhesion formation.

Abstract
BACKGROUND Postoperative fascial dehiscence and open abdomen are severe postoperative complications and are associated with surgical site infections, fistula, and hernia formation at long-term follow-up. This study was designed to investigate whether intraperitoneal implantation of a composite prosthetic mesh is feasible and safe. METHODS A total of 114 patients with postoperative fascial dehiscence and open abdomen who had undergone surgery between 2001 and 2009 were analyzed retrospectively. Contaminated (wound class 3) or dirty wounds (wound class 4) were present in all patients. A polypropylene-based composite mesh was implanted intraperitoneally in 51 patients, and in 63 patients the abdominal wall was closed without mesh implantation. The primary endpoint was incidence of incisional hernia, and the incidence of enterocutaneous fistula was a secondary endpoint. RESULTS The incidence of enterocutaneous fistulas after wound closure post-fascial dehiscence (13% vs. 6% without and with mesh, respectively) or post-open abdomen (22% vs. 28% without and with mesh, respectively) was not significantly different. The incidence of incisional hernia was significantly lower with mesh implantation compared with no-mesh implantation in both contaminated (4% vs. 28%; p = 0.025) and dirty abdominal cavities (5% vs. 34%; p = 0.01). CONCLUSIONS Intra-abdominal contamination is not a contraindication for intra-abdominal mesh implantation. The incidence of enterocutaneous fistula is not elevated despite the presence of contamination. The rate of incisional hernias is significantly reduced after intraperitoneal mesh implantation for postoperative fascial dehiscence or open abdomen.

Abstract
AIM Despite advances in surgical technique, parastomal herniation is common. This systematic review aims to assess the efficacy of prophylactic mesh at primary operation in reducing the incidence of parastomal hernia. METHOD Medline, EMBASE and CENTRAL were searched for relevant publications between January 1980 and January 2010. The search strategy included text terms and MESH headings for parastomal hernia, mesh and prevention and/or prophylaxis of hernia. No language restrictions were applied. Bibliographies from the papers requested in full were manually checked. All randomized controlled trials were included regardless of the language of publication. Results were extracted from the papers by two observers independently on a predefined data sheet. Disagreements were resolved by discussion. REVMAN 5 was used for statistical analysis. RESULTS Of 27 possible studies three randomized controlled trials fulfilled the criteria for systematic review, with a total of 128 patients (mesh 64, no mesh 64). The two study groups were well matched demographically. The incidence of parastomal hernia in the mesh group was 12.5% (8/64) compared with 53% (34/64) in the control group (P < 0.0001). There was no difference in mesh related morbidity in the two groups. CONCLUSION Although only three trials with 128 patients fulfilled the criteria for this systematic review, the data suggest that the use of prophylactic prosthetic mesh at the time of primary stoma formation reduces the incidence of parastomal hernia.

Abstract
Hernia surgery continues to draw the attention of surgeons, patients, and the industry. This strong interest has driven the establishment of professional medical societies with the sole purpose of furthering the understanding of hernias and hernia repair. In the more than 100 years of development, industry has played a major role in advancing the technology to perfect the performance of hernia repair with the hope of establishing the "best" technique and its associated technology. However, with the development of newer prosthetics and approaches to hernia repair, many surgeons do not fully understand the properties of the available prosthetics. The goal of this review is to highlight the different types of meshes in an effort to clarify to surgeons what types of materials are available to them and how to select an appropriate one for a given case.

Abstract
OBJECTIVES Laparoscopic incisional and ventral hernia repair (LIVHR) is widely used although its clinical indications are often debated. The aim of this study was to retrospectively describe the experience of our surgical centre in order to establish the safety, efficacy, and feasibility of LIVHR using PARIETEX(™) Composite mesh (Covidien, Mansfield, MA, USA). MATERIAL AND METHODS Between January 2007 and November 2010, 87 patients were admitted to the Division of General Surgery of Aosta, with the diagnosis of abdominal wall hernia and underwent laparoscopic repair using PARIETEX(™) Composite mesh. The type and size of surgical defects, mean operative time, morbidity, mortality and rate of recurrence at one-year follow-up were retrospectively analysed. RESULTS We performed 87 LIVHR: 51.7% for incisional hernia and 48.3% for epigastric or umbilical hernias. Mean operative time was 100 min., conversion rate was 3.4%. The mean size of abdominal defect was 6 cm (range: 2-15); in relation to umbilical hernias, mean size was 5.4 cm (range: 2-8). The mortality rate was 0%; overall morbidity was 16%. At one-year follow-up, we observed two cases of hernia recurrences. CONCLUSIONS LIVHR using PARIETEX(™) Composite mesh is an effective and safe procedure with very low morbidity and low rates of postoperative pain and recurrence, especially in hernias with diameter of between 5 and 15 cm and in obese patients without previous laparotomies.

Abstract
The laparoscopic ventral hernia repair with preperitoneal placement of mesh minimizes the complications related to the intraperitoneal position of mesh and fixating devices. It allows safe use of conventional and less expensive polypropylene mesh. The prospectively collected data of 68 patients who underwent laparoscopic transabdominal preperitoneal mesh hernioplasty, for different types of ventral hernias between January 2005 and December 2009 was retrospectively reviewed. The study included 68 patients, 16 males and 52 females with a mean age 51.1 ± 11.1 years (range 23-74 years). Most of the hernias (67.6%) were in the midline position. The mean size of the defect was 30.8 ± 24.4 cm2 (range, 4-144 cm2) and the mean mesh size was 237.8 ± 66.8 cm2 (range, 144-484 cm2). The mean operating time was 96.7 ± 16.7 min (range 70-150 min). All repairs were done with polypropylene mesh. The mean postoperative hospital stay was 1.5 ± 0.6 days (range, 1-4 days). Nineteen patients (27.9%) suffered from postoperative complications. Four patients (5.8%) were detected to have seroma formation. There were two recurrences (2.9%). The mean follow up was 22.7 ± 13.4 months (range, 6-48 months). The laparoscopic preperitoneal ventral hernia repair with polypropylene mesh is cheaper and has acceptable postoperative outcomes. Peritoneal coverage of the mesh not only acts as a barrier between mesh and bowel and thereby prevents adhesions, it also provides an additional security of fixation. This is a safe and feasible option of ventral hernia repair in expert hands. However, for proper validation of these conclusions a long term prospective clinical trial is required.

Abstract
AIMS OF THE STUDY To evaluate post-operative complications and the recurrence rate after repair of large ventral incisional hernia with an open technique using intraperitoneal composite mesh and an associated aponeurotic overlay. PATIENTS AND METHODS This prospective study included a total of 280 patients who underwent repair of large incisional hernia using Parietex(®) composite mesh. RESULTS The post-operative mortality rate was 0.35%. Six patients (2%) developed subcutaneous surgical site infection without infection of the prosthesis. Six other patients (2%) developed a deep-seated infection; in three cases, the mesh had to be removed. Nine patients (3.2%) developed recurrent incisional hernia. CONCLUSION Large ventral incisional hernias can be effectively treated by the intraperitoneal placement of Parietex(®) composite mesh overlaid by an aponeurotic graft; the incidence of complications in this prospective study was very low.

Abstract
We evaluated the efficacy and safety of the use of a composite PTFE/polypropylene patch, Ventralex (Davol Inc., C.R. Bard, Inc., RI, USA), to repair, concurrent with laparoscopy, umbilical hernia in 51 postmenopausal women. After laparoscopy, patients were submitted to the hernia repair by a patch intraperitoneally placed behind the hernia. Primary outcomes included complication rates, while hernia recurrence was the secondary outcome. Patient age range was 58 ± 4.3 years, the size of patches was small in 17.6% of women, medium in 68.7% and large in 13.7%. Seventy-six percent of patients had an ASA I-II score, the mean operating time for hernia repair was 7 ± 2 minutes with 15 cc of related blood loss, with 1.8 days of hospital stay. The visual analogue scale was 0-3 for 62.7%, 4-6 for 27.5% and 7-10 for 9.8% of women. All laparoscopic and umbilical hernia repair terminated without any further intra or postoperative complications, with 36 months of follow-up; none of the patients showed recurrences. Combining laparoscopy and intraperitoneal mesh repair appears to be indicated for umbilical hernia treatment in post-menopausal patients undergoing laparoscopy, resulting in a safe and easy procedure, with short hospital stay and fast dismissal, with no major morbidity or recurrence.

Abstract
BACKGROUND Adhesions are a well-known and very common complication to surgery. Their extent and severity varies according to type and number of surgeries, use of intraabdominal mesh, and presence of peritonitis. Adhesions cause increased morbidity and mortality, with subsequent socioeconomic consequences. This review aimed to identify existing literature on noninvasive radiologic techniques for identification of intraabdominal adhesions. METHODS A structured literature search of medical databases was conducted. English literature published until September 2009 and relevant references were included and assessed. RESULTS The search identified transabdominal ultrasonography (TAU) and cine magnetic resonance imaging (cine MRI) as relevant tools matching the search criteria. In all, 12 publications concerning TAU and 4 publications concerning cine MRI were identified. All but one of these publications had the methodologic limitation of not being blinded, which influenced the final sensitivity, specificity, and accuracy. CONCLUSION Both TAU and cine MRI seem able to identify intraabdominal adhesions using visceral slide with accuracy of 76% to 92%. Unfortunately, the studies are biased by being nonblinded. Accordingly, a need exists for a systematic well-conducted double-blinded comparative study to validate these radiologic techniques.

Abstract
BACKGROUND Laparoscopic ventral hernia repair (LVHR) has gained worldwide acceptance, due to its minimally invasive character, feasibility and low rate of complications. Animal experiments have shown marked adhesions to the intraperitoneal mesh (IPM), the clinical consequences being unclear. This study aimed to describe the extension of adhesions to the mesh, 5-7 years after LVHR, using two validated non-invasive radiologic methods. METHODS Real-time transabdominal ultrasonography (TAU) and cine magnetic resonance imaging (MRI) was applied to 30 patients with prior LVHR and implantation of IPM (Intramesh W3, Cousin Biotech, France). The visceral slide was measured in nine predefined abdominal segments. Values <or=1 cm were defined as an area with adhesion. RESULTS The mean time between LVHR and TAU/cine MRI was 67 months (range, 58-80 months). We found adhesion to the mesh in 90% of the patients using TAU and 100% of the patients using cine MRI. In the latter, 65% were between the bowel and IPM. CONCLUSIONS LVHR is known to reduce recurrences and postoperative complications, while improving patient outcome. The intraperitoneal placement of the mesh has been shown to induce adhesions; the amount and extension in the clinical setting is unclear. The present study showed a marked proportion of adhesions to the mesh with an average surgery to scan time of 5.6 years, despite an anti-adhesive barrier on the visceral surface of the mesh. Together with existing data, this result increases the concern related to the long-term consequences of an IPM. As a consequence, a comprehensive and comparable test system for medical devices, i.e. IPM, is needed.

Abstract
BACKGROUND The purpose of this study was to characterize the adhesion characteristics of absorbable- and nonabsorbable-barrier-coated meshes and to report adhesiolysis-related complications during laparoscopic re-exploration after prior ventral hernia repair. METHODS Under an IRB-approved protocol, patients undergoing laparoscopic re-exploration after prior intraperitoneal mesh placement were prospectively graded intraoperatively for adhesion tenacity (0-4), adhesion surface area (0 = 0%, 10 = 100%), and ratio of adhesiolysis time to mesh surface area (min/cm(2)). Adhesiolysis-related complications were also recorded. Data are given as mean ± SD. Statistical significance (P < 0.05) was determined using the t test and Fisher's exact test. RESULTS From March 2006 to March 2009, 69 patients underwent laparoscopic surgery after prior intraperitoneal mesh placement for ventral hernia repair. Previous meshes were absorbable-barrier-coated mesh (n = 18), permanent-barrier composite mesh [Composix® (n = 17)], permanent-barrier noncomposite mesh [DualMesh® (n = 14)], uncoated polypropylene mesh (n = 12), and biologic mesh (n = 8). Indications for laparoscopic re-exploration were recurrent ventral hernia (n = 58), chronic pain (n = 3), cholecystectomy (n = 3), parastomal hernia (n = 2), small bowel obstruction (n = 1), nephrectomy (n = 1), and Nissen fundoplication (n = 1). Adhesions to DualMesh were less tenacious (P < 0.05) compared to all other meshes. Surface area of adhesions to DualMesh were less (P < 0.05) than to Composix and to uncoated polypropylene mesh, but not to absorbable-barrier-coated and biologic meshes. Adhesiolysis time:mesh surface area was less (P < 0.05) for DualMesh compared to Composix, uncoated polypropylene, and biologic mesh, but not to absorbable-barrier-coated mesh. Adhesiolysis-related complications occurred in two (16.7%) (P = ns) patients with uncoated polypropylene mesh, one cystotomy and one enterotomy; both were repaired laparoscopically. There were two (16.7%) (P = ns) conversions to an open procedure: one converted patient had Composix (6.7%) and one had absorbable-barrier-coated mesh (5.9%). There were no adhesiolysis-related complications with these meshes. There were no adhesiolysis-related complications or conversions to open in the DualMesh or biologic mesh groups. CONCLUSIONS Adhesion characteristics of mesh placed intraperitoneally and adhesiolysis-related complications during laparoscopic re-exploration after ventral hernia repair are associated with unique properties of the mesh and/or barrier.

Eighty-five redo surgeries after 733 laparoscopic treatments for ventral and incisional hernia: adhesion and recurrence analysis. Hernia 2010; 14:123-9. [PMID: 20155431 DOI: 10.1007/s10029-010-0637-4] [Citation(s) in RCA: 49] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2008] [Accepted: 01/29/2010] [Indexed: 10/19/2022]
Abstract
INTRODUCTION This report reviews the clinical and functional outcomes of implanted meshes during a second-look evaluation of 85 cases after a large number (733) of laparoscopic incisional and ventral hernia repairs (LIVHR), of which 608 were controlled throughout a period of 5 to 10 years. This report demonstrates a minimal occurrence of adhesions and a low rate of recurrences and other complications related to mesh usage. METHODS Eighty-five re-operated cases after LIVHR were reviewed retrospectively. In every redo surgery, the first trocar was always inserted on a lateral side, external to the previous skin incisions of the transabdominal fixations. Mueller's adhesion scale was used to estimate adhesion severity (Mueller 0 indicates no adhesion; Mueller I indicates adhesion of the omentum; and Mueller II indicates serosal adhesions). The mechanism of recurrence is of paramount interest and is analyzed herein. If recurrence was observed, the defect was closed and a larger mesh of Parietex was implanted under the previous one, with transparietal fixation achieved by pulling the threads with the Endoclose device. RESULTS In all of our "second-look" surgeries, the neoperitoneum perfectly covered the mesh. In 47.05% of the cases, we observed no adhesions (Mueller 0), 42.3% had adhesions of the omentum (Mueller I), and 10.58% had serosal adhesions (Mueller II). There was no shrinking or wrinkling of the prosthesis in any of the cases, confirming its total peritonization on the anterior abdominal wall. Within the first 3 years, only 4.1% of the controlled patients contracted recurrences, with a mean follow-up of 52 months. CONCLUSION With the double-suturing technique used for LIVHR and the use of a composite mesh, we observed a low rate of recurrences and limited side effects as compared with the use of tacks intra-abdominally. Redo surgeries after LIVHR are feasible, but care must be taken due to unpredictable mesh adhesions.

Abstract
BACKGROUND Laparoscopic ventral and incisional hernia repair has been reported in a number of small trials to have equivalent or superior outcomes to open repair. METHODS Randomized controlled trials comparing laparoscopic and open incisional or ventral hernia repair with mesh that included data on effectiveness and safety were included in a meta-analysis. RESULTS Eight studies met the inclusion criteria. There was no difference between groups in hernia recurrence rates (relative risk 1.02 (95 per cent confidence interval (c.i.) 0.41 to 2.54)). Duration of surgery varied. Mean length of hospital stay was shorter after laparoscopic repair in six of the included studies; the longest mean stay was 5.7 days for laparoscopic and 10 days for open surgery. Laparoscopic hernia repair was associated with fewer wound infections (relative risk 0.22 (95 per cent c.i. 0.09 to 0.54)), and a trend toward fewer haemorrhagic complications and infections requiring mesh removal. CONCLUSION Laparoscopic repair of ventral and incisional hernia is at least as effective, if not superior to, the open approach in a number of outcomes.

Abstract
BACKGROUND This study was designed to evaluate the long-term complications and recurrences of laparoscopic repair of incisional hernias. Very few studies evaluate objectively the long-term results of laparoscopic incisional hernia repair. METHODS Data for 200 consecutive patients who underwent laparoscopic incisional hernia repair (LIHR) in a university teaching hospital using a standardized procedure between January 1994 and December 2006 were collected prospectively. The median follow-up was 6 (range, 1-12) years. RESULTS The conversion rate from laparoscopic to open approach was 2.5% (205 initial patients). Mean operative time was 51 minutes; 63% of these patients were discharged the day of surgery. Mean hospital stay was 2.6 days. There was an overall postoperative complication rate of 15%. We had four small bowel injuries repaired laparoscopically, and one patient died as a result of a sepsis. Postoperative pain was limited, with a mean analgesics requirement of 6.8 (range, 0-30) days. During a mean follow-up of 60 (range, 12-144) months, the recurrence rate was 6.2%, which developed within 1 year of the operation and associated with body mass index >37, defect size >10 cm, and multiple Swiss-cheese defects (p < 0.01). CONCLUSIONS 1) Intra-abdominal composite mesh is good tolerance. 2) The recurrence rate is low and within 1 year of the operation. 3) The long-term morbidity with LIHR is moderate. 4) The risk of intestinal injury is not predictable. 5) Reoperations can be performed with sufficient guarantee using laparoscopy.

[PMID: 19245914 DOI: 10.1016/j.amjsurg.2008.11.003] [Citation(s) in RCA: 56] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2008] [Revised: 11/12/2008] [Accepted: 11/12/2008] [Indexed: 11/25/2022]
Abstract
INTRODUCTION The ideal prosthetic material for ventral hernia repair has yet to be described. Each prosthetic material has unique advantages and disadvantages in terms of tissue ingrowth, adhesion formation, and shrinkage profiles. Polyester-based mesh has shown minimal shrinkage and excellent tissue ingrowth in animal models. However, the macroporous, braided nature of this material has raised several concerns regarding the incidence of infections, fistulas, and bowel obstructions. We have reviewed our experience with polyester-based mesh for the repair of ventral hernias. METHODS All patients undergoing ventral hernia repair at the Case Comprehensive Hernia Center at University Hospitals of Cleveland from December 2005 to April 2008 were included. Laparoscopic cases underwent intraperitoneal placement of a polyester-based mesh with a collagen hydrogel anti-adhesive barrier. The mesh was sized for at least 4 cm of fascial overlap, and transfascial fixation sutures and titanium spiral tacks were used routinely to secure the mesh to the abdominal wall. Those cases deemed inappropriate for laparoscopic ventral hernia repair underwent open repair. Open ventral hernia repairs were performed using a retrorectus repair, placing the mesh in an extraperitoneal position. Unprotected polyester mesh was used in these cases. Pertinent data included patient demographics, surgical details, postoperative outcomes, and long-term follow-up evaluation. RESULTS During the study period 109 patients underwent ventral hernia repair with polyester mesh. Seventy-nine patients had a laparoscopic repair, and 30 patients had an open repair. The mean age was 57 years, with a mean body mass index of 33 kg/m(2), and American Society of Anesthesia score of 2.6. The patients had undergone 2.1 prior abdominal surgical procedures, and 42 patients had recurrent hernias. Surgical details for the laparoscopic repair and open repair were as follows: mean defect size, 116 versus 403 cm(2); mesh size, 367 versus 1,055 cm(2); and surgical times, 132 versus 170 minutes, respectively. The average hospital stay was 4.2 days for the laparoscopic repair and 5.8 days for the open repair groups. With a mean follow-up period of 14 months (range, 2-28 mo) in the laparoscopic repair group, 1 patient (1.4%) developed a mesh infection (with a history of a prior methicillin-resistant Staphylococcus aureus mesh infection), 1 patient (1.4%) developed a small-bowel obstruction remote to the mesh on re-exploration, and there were no fistulas. With a mean follow-up period of 11 months (range, 2-21 mo) in the open repair group, 3 wound infections (13%) occurred, 2 involved the mesh, which was salvaged with local wound care in 1, and required partial mesh resection in the other, and there were no bowel obstructions or fistulas during the follow-up evaluation. CONCLUSIONS This study shows that in this complex group of patients, polyester mesh placed during ventral hernia repair results in acceptable infection rates, and no direct bowel complications or fistulas. Given the macroporous nature of the mesh, each case of infection was treated successfully with local wound measures or partial mesh resection. Polyester-based meshes with an anti-adhesive barrier appear safe for intraperitoneal placement.

Abstract
BACKGROUND To non-invasively identify incisional hernia repair implanted synthetic meshes with MRI, and also focusing on the evaluation of postsurgical complications such as adhesions. METHODS A total of 43 patients underwent either laparoscopic intraperitoneal onlay-mesh or open abdominal wall repair using preperitoneal layers. The patients were examined using a true-fast-imaging-with-steady-state-precession (trueFISP)-sequence in transverse/sagittal orientation with a section-by-section dynamic depiction of induced visceral slide. A 9-segment-abdominal-map was used to document the adhesion location/type. The MR-images were analysed regarding hernia relapse, layer-morphology, rectus-abdominis muscle-condition, and abdominal wall mobility. In 12 patients pre- and postsurgery-MRI was performed. RESULTS Time range between surgery and examination was 6-36 months. In all laparoscopy-patients the meshes were identified. For open surgery the mesh was not visualized in 20, but was seen in 6 cases. A total of 11 cases showed a recurrent hernia. Seventy intraabdominal adhesions were detected. Fifteen patients had restricted mobility. 20 patients showed an rectus-abdominis-muscle-asymmetry. Comparing pre- and post-op-MRI, 6 out of 8 patients with open repair showed thick scar-plaques. Three patients with open repair had new adhesion-formations postoperatively. CONCLUSION Functional cine MRI is suitable for follow-up studies in patients after hernia repair to detect and evaluate the implanted meshes. Typical complications like intestinal adhesions and abdominal wall dysmotility can be assessed as well.

Abstract
BACKGROUND This is a prospective study of prophylactic mesh placement in the preperitoneal space at the time of stoma formation to prevent parastomal hernia. METHODS Patients undergoing elective permanent stoma formation and resiting of a stoma were included. Patients with peritoneal contamination were excluded. A 6x6-cm polypropylene mesh was placed in the preperitoneal space (no stitches), and a circular hole was made to let the bowel come through with ease and the stoma was constructed. At follow-up, the patients were examined standing and lying down for parastomal hernia. In the event of clinical uncertainty, a CT scan was done. RESULTS A total of 42 patients (20 women, 22 men, mean age 61 years) were eligible for the study. The patients were followed up for a mean of 31 months (range 9-68 months). There were 29 end-colostomies and 8 end-ileostomies and 5 stomas resited. Four parastomal hernias were detected during the follow-up period (9.52%). One required repair due to an ill-fitting stoma bag and leakage. The other three were asymptomatic. One patient developed stomal necrosis which required a new segment of bowel to be brought out through the same opening and the underlying mesh was left undisturbed. CONCLUSIONS The results of the 2-year follow-up in this study (incidence of parastomal herniation 9.5%) along with available evidence in the literature (incidence 0-8.3%), compared to the results of repair make a strong case for the use of a mesh at the time of initial surgery for the formation of any permanent stoma to prevent parastomal herniation.

Abstract
BACKGROUND Today, the laparoscopic approach is a standard procedure for the repair of incisional hernias. However, the direct contact of visceral organs with mesh material is a major issue. PATIENTS AND METHODS This prospective observational study presents the data of 344 patients treated for incisional and parastomal hernias with a new mesh made of polyvinylidene fluoride (PVDF; Dynamesh IPOM) between May 2004 and January 2008 with a minimum follow-up of 6 months. The median follow-up of 297 patients after incisional hernias totaled 24 months and 20 months for 47 patients with parastomal hernias. Incisional hernias were repaired using an IPOM technique. For parastomal hernias, a recently described sandwich technique was used with two meshes implanted in an intraperitoneal onlay position. RESULTS The recurrence rate for incisional hernias was 2/297 = 0.6% and 1/47 = 2% for parastomal hernias. Three patients developed a secondary infection after surgical revision or puncture of a seroma. One patient had a bowel fistula through the mesh, with an abscess in the hernia sac. In all cases, the infection healed and the mesh could be preserved. No long-term mesh-related complications have been observed. CONCLUSION The laparoscopic repair of incisional and parastomal hernias with meshes made of PVDF (Dynamesh IPOM) revealed low recurrence and, overall, low complication rates. Especially in cases of infection, the material proved to be resistant without clinical signs of persistent bacterial contamination. Mesh-related complications did not occur during the follow-up.
