Retrospective analysis of umbilical, epigastric, and small incisional hernia repair using the Ventralex™ hernia patch

Primary Uncomplicated Ventral Hernia Repair: Guidelines and Practice Patterns for Routine Hernia Repairs

Surgical repair of primary umbilical and epigastric hernias are among the most common abdominal operations in the world. The hernia defects range from small (<1 cm) to large and complex even in the absence of prior incision or repair. Mesh has generally been shown to decrease recurrence rates, and its use and location of placement should be individualized for each patient. Open, laparoscopic, and robotic approaches provide unique considerations for the technical aspects of primary repair with or without mesh augmentation.

Parietex™ Composite Ventral Patch for primary and incisional hernia repair

BACKGROUNDS

Ventral hernia repair with a preformed device is a frequent intervention, but few reports exist with Parietex™ Composite Ventral Patch. The aim was to evaluate the results of this mesh with the open intraperitoneal onlay mesh (open IPOM) technique.

METHODS

Observational retrospective single institution study of all consecutive patients intervened for ventral or incisional hernia with a diameter inferior to 4 cm, from January 2013 to June 2020. The surgical repair was performed according to the open IPOM technique with Parietex™ Composite Ventral Patch.

RESULTS

A total of 146 patients were intervened: 61.6% with umbilical hernias, 8.2% with epigastric hernias, 26.7% with trocar incisional hernias, and 3.4% with other incisional hernias. The global recurrence rate was 7.5% (11/146). Specifically, it was 7.8% in umbilical hernias, 0% in epigastric hernias, 7.7% in trocar incisional hernias and 20% (1/5) in other incisional hernias. The median time for recurrence was 14 months (IQR: 4.4-18.7). The median indirect follow-up was 36.9 months (IQR: 27.2-49.6), and the median presential follow-up was 17.4 months (IQR: 6.5-27.3).

CONCLUSION

The open IPOM technique with a preformed patch offered satisfactory results for the treatment of ventral and incisional hernias.

Ventralex™ ST Hernia Patch Repair for Small Umbilical Hernia is Safe and Effective: A Retrospective Cohort Study

Background: Hernia patches for umbilical hernia repair have gained popularity due to their short operation time and ease of use. However, up to 10% re-operation and 8% recurrence rates at 2-year follow-up have been published. This retrospective cohort study presents the long-term results of the hernia patch technique for umbilical hernia repair. Methods: All adult patients who underwent a primary umbilical hernia repair at Oulu University Hospital hernia surgery units during 2014-2018 were included in the study. The primary outcome measure was recurrence rate. Secondary outcomes were complications and re-operation rate. Results: A total of 619 elective primary umbilical hernia repairs were performed during 2014-2018. The major technique used was Ventralex™ ST hernia patch repair (79.0%, 488/619) for small hernias with a mean width of 1.8 (SD 0.79) cm. Most of the patches (84.7%, 414/488) were placed in the preperitoneal space. Hernia recurrence rate of patient operated on using Ventralex™ ST hernia patch was 2.5% (12/488) during a mean follow-up time of 68 (SD 16, 43-98) months. Re-operation rate for another reason than recurrence was 1.6% (8/488). Clavien-Dindo complications ≥3 occurred in 4.1% (20/488) of cases and surgical site infection rate was 3.3% (16/488). Conclusion: Umbilical hernia repair using a Ventralex™ ST hernia patch placed in preperitoneal space have acceptable results in terms of recurrence and re-operations in this cohort study.

Onlay mesh repair for treatment of small umbilical hernias ≤ 2 cm in adults: a single-centre investigation

PURPOSE

Previous studies on the repair of small umbilical hernias have suggested a lower recurrence rate with mesh compared to suture repair. An important question is in what anatomical position the mesh should be placed. The purpose of this study was to investigate the outcome of using a standardized 4 × 4 cm onlay-mesh for umbilical hernias ≤ 2 cm.

METHODS

A retrospective study was conducted at a single centre in Sweden on all umbilical hernia repairs during 2015-2019. The follow-up time was at least four months. Patients were identified using the hospital medical database. Repairs performed with suture or a sublay, ventral patch and laparoscopic mesh positioning were excluded. The patient's demographics, comorbidities, intra-and post-operative details were considered. The primary outcome was surgical site complications within 30 days. The secondary outcome was a recurrence.

RESULTS

80 patients were repaired with a small onlay-mesh for an umbilical hernia ≤ 2 cm. The median (range) follow-up time was 29.0 (4.3-50.1) months. The median age was 46 (26-76) years old. The median body mass index was 28 (19-38) kg/m2. The male to female ratio was 2:1. 4 patients were identified with a surgical site post-operative complication; three with seromas and one with a superficial wound infection. 3 of these were given antibiotics. 2 patients were treated with wound openings bedside. There were no registered cases of recurrence.

CONCLUSIONS

Repairing small umbilical hernias with a small onlay-mesh was safe with a low surgical site complication rate. Randomized trials are needed to assess whether mesh can reduce recurrences in umbilical hernia repairs ≤ 2 cm.

Guidelines for Treatment of Umbilical and Epigastric Hernias From the European and Americas Hernia Societies-A Web-Based Survey on Surgeons' Opinion

Background and aims: The European and Americas Hernia Society's (EHS and AHS) Guidelines on the treatment of primary midline ventral hernias were launched to guide surgeons. As a part of a dissemination plan of the guideline, this study aimed to evaluate the level of consensus between recommendations and the current surgical practices of EHS and AHS members before implementation. Material and methods: A questionnaire was constructed including questions on the current practice of the members and nine selected key recommendations from the guidelines. An on-stage consensus voting was performed at the EHS Congress in Hamburg 2019 followed by a SurveyMonkey sent to all EHS and AHS members. Consensus with a recommendation was defined as an agreement of ≥70%. Results: A total of 178 votes were collected in Hamburg. A further 499/1,754 (28.4%) of EHS and 150/1,100 (13.6%) of AHS members participated in the SurveyMonkey. A consensus was reached for 7/9 (78%) of the recommendations. The two recommendations that did not reach consensus were on indication and the technique used for laparoscopic repair. In current practice, more AHS participants used a preformed patch; 50.7% (76/150) compared with EHS participants 32.1% (160/499), p < 0.001. Conclusion: A consensus was achieved for most recommendations given by the new guideline for the treatment of umbilical and epigastric hernias. Recommendations that did not reach consensus were on indication and technique for laparoscopic repair, which may reflect the lack of evidence on these topics.

SUMMER Trial: mesh versus suture repair in small umbilical hernias in adults-a study protocol for a prospective randomized double-blind multicenter clinical trial

Background

Small umbilical hernia repair is one of the most common surgical performances in general surgery. Yet, a gold standard procedure for the repair is still lacking today. There is an increasing evidence that mesh could be advantageous compared to suture repair in lowering recurrence rates. An additional important question remains with regard to the optimal anatomical positioning of the mesh. We hypothesize that the use of an onlay mesh in small umbilical hernia defects can reduce recurrence rates without increasing the complications compared to a simple suture repair.

Methods

A prospective, national, multicenter, randomized, double-blind clinical trial comparing a standardized 4 × 4 cm onlay mesh to a conventional suture repair will be conducted. A total of 288 patients with a primary elective umbilical hernia ≤ 2 cm from 7 participating Swedish surgical centers will be enrolled. Intraoperative randomization will take place using a centralized web-based system resulting in total allocation concealment. Stratification will be done by surgical site and by defect size. Trial participants and follow-up clinical surgeons will be blinded to the assigned allocation. The primary outcome assessed will be postoperative recurrence at 1 and 3 years. Secondary outcomes assessed will be postoperative complications at 30 days and pain 1 year after surgery.

Discussion

Currently, there has been no randomized clinical trial comparing the recurrence rates between an onlay mesh repair and a simple suture repair for small umbilical hernia defects. How to best repair a small umbilical hernia continues to be debated. This trial design should allow for a good assessment of the differences in recurrence rate due to the large sample size and the adequate follow-up. Surgeons’ concerns surrounding optimal anatomical positioning and fear for larger required dissections are understandable. A small onlay mesh may become an easy and safe method of choice to reduce recurrence rates. Guidelines for small umbilical hernia repairs have stressed the need for reliable data to improve treatment recommendations. We can expect that this trial will have a direct implication on small umbilical hernia repair standards.

Prosthetic meshes for hernia repair: State of art, classification, biomaterials, antimicrobial approaches, and fabrication methods

Worldwide, hernia repair represents one of the most frequent surgical procedures encompassing a global market valued at several billion dollars. This type of surgery usually requires the implantation of a mesh that needs the appropriate chemical, physical and biological properties for the type of repair. This review thus presents a description of the types of hernias, current hernia repair methods, and the state of the art of prosthetic meshes for hernia repair providing the most important meshes used in clinical practice by surgeons working in this area classified according to their biological or chemical nature, morphology and whether bioabsorbable or not. We emphasise the importance of surgical site infection in herniatology, how to deal with this microbial problem, and we go further into the future research lines on the production of advanced antimicrobial meshes to improve hernia repair and prevent microbial infections, including multidrug-resistant strains. A great deal of progress has been made in this biomedical field in the last decade. However, we are still far from an ideal antimicrobial mesh that can also provide excellent integration to the abdominal wall, mechanical performance, low visceral adhesion and minimal inflammatory or foreign body reactions, among many other problems.

Laparoscopy-assisted repair with Ventralex ST Hernia Patch for a small subcostal hernia: A case report

A 55-year-old woman with a history of right hepatic lobectomy via a Benz incision presented for evaluation of a new abdominal bulge in the right upper quadrant. We diagnosed an incisional hernia, but because we could neither reduce the hernia contents nor locate the orifice, we performed a laparoscopic evaluation. Laparoscopy revealed subcostal herniation of the greater omentum via a 2-cm defect on the caudal side of the right ribs, which we repaired using a Ventralex ST Hernia Patch. Laparoscopic placement of this mesh with straps allowed for reliable deployment, fixation, and confirmation of defect closure, including the cranial aspect-often a major challenge in subcostal hernia repair.

Outcomes of Laparoscopic-Assisted, Open Umbilical Hernia Repair

Umbilical hernia repair (UHR) is one of the most commonly performed hernia operations with reported recurrence rate from 1% to 54%. Our aim was to describe an open, laparoscopic-assisted (OLA) technique and its outcome in an institutional review board-approved prospective study at a tertiary hernia center from 2008 to 2019. All patients underwent a standard periumbilical incision, open dissection of the hernia, and closure of the fascial defect with laparoscopic intraperitoneal onlay mesh (IPOM) fixation with permanent tacks. A total of 186 patients were identified who underwent an OLA UHR repair. Patient characteristics are as follows: average age 52.8 ± 12.5 years, male gender 79.6%, body mass index 31.4 ± 8.0 kg/m², and average hernia defect size of 2.8 ± 4.8 cm². Forty-one (22.0%) patients had previous failed repair. Sixty-nine (37.1%) patients had another procedure performed at the time of the UHR, most commonly a laparoscopic transabdominal inguinal hernia repair (58%). The mean operative time was 87.3 ± 51.2 minutes, but only 63.9 ± 31.9 minutes for patients undergoing an OLA repair. There were no recurrences (0%) on abdominal physical or radiographic examination with an average follow-up of 16.5 ± 17.7 months. Postoperative complications included wound erythema (2.7%), hematomas (1.1%), seromas (2.7%), and 4.3% received postoperative oral antibiotics. One person was readmitted for seroma drainage, and another required reoperation for small bowel obstruction unrelated to the hernia repair. One patient had chronic pain requiring tack removal. With moderate follow-up, an OLA UHR with mesh appears to be a durable repair with favorable results, including those patients with recurrent hernias.

Intraperitoneal Tension-free Repair of a Small Midline Ventral Abdominal Wall Hernia: Randomized Study with a Mean Follow-up of 3 Years

Funding received from Cousin Biotech, Wervicq Sud, France, and CR Bard Inc., Cranston, RI. The aim of this prospective randomized study was to determine the long-term recurrence and complication rates after small abdominal wall hernia repair with two different bilayer prostheses. Hernia repair using prosthetic mesh material has become the preferred method of repair, because the recurrence rates are much lower than with conventional repair techniques. The use of a hernia bilayer patch, composite expanded polytetrafluoroethylene (ePTFE)-polypropylene, with intraperitoneal placement behind the hernia defect, through a small incision, may be efficient, safe, and cost-effective. This study is a randomized, single-institution trial, including 83 selected consecutive patients with primary (umbilical, epigastric) or incisional anterior abdominal wall defects from 2 to 5 cm. Hernia repair was performed by direct local access in ambulatory surgery; the prosthesis used was a circular bilayer with an inner face in ePTFE to avoid bowel adhesion. One group was treated with a Ventralex® Hernia Patch (Bard USA). The second group was treated with a Cabs'Air® Composite (Cousin Biotech France), which was delivered with two to four fixation sutures and a balloon to properly deploy the mesh intraperitoneally. Patients’ characteristics and operative and postoperative data were prospectively collected. The primary outcome was late recurrence. Secondary outcomes included, pain, discomfort and quality of life before and after (3 months) surgery using the SF-12 questionnaire, patient-surgeon satisfaction, and early and late complications. Among 98 patients, 83 were included in the study protocol between January 2007 and August 2011. The two groups were comparable according to pre- and intraoperative data. According to surgeon experience, placement of the Cabs'Air® device was significantly faster ( P = 0.01) and easier. At 3 months, there was significantly less pain and less discomfort for the Cabs'Air® group and patient satisfaction rate was higher. This was confirmed by all components of the SF-12 questionnaire. Long-term follow-up was available for 77 patients. The mean follow-up was similar for the two groups (42 months; range, 14 to 70 months). At this point, for the Ventralex® group, there were four recurrences (11.7%); one mesh infection; one small bowel obstruction; and six cases (15.7%) of severe pain resulting from a mass syndrome (shrinkage) with a sense of the presence of a foreign body. Six reoperations (15.6%) were required with explant of the prosthesis. There were no recurrences or late complications in the comparative group. The Ventralex® Hernia Patch is associated with inconsistent deployment, spreading, or shrinkage, which account for late complications and decreases the overlap, which contributes to the recurrence rate. The Cabs'Air®-associated balloon facilitates superior deployment of the prosthesis allowing for good fixation with four sutures.

Is mesh always necessary in every small umbilical hernia repair? Comparison of standardized primary sutured versus patch repair: retrospective cohort study

Purpose

A retrospective analysis was carried out to compare the results of patch repair using ready-made, synthetic mesh (PR) and sutured repair (SR) based on standard protocols. The accumulated recurrence rate was accepted as the primary outcome. Pain at rest and during exercise, cosmetic effect and treatment satisfaction were chosen as the secondary endpoints.

Methods

Adult patients after elective, open surgical repair of a single, primary umbilical hernia < 2 cm in diameter were included. Patients with incarceration or strangulation, after previous umbilical hernia repair or other abdominal surgical interventions were excluded. In the SR group, single-layer sutures were placed using the short-stitch technique. In PR group, a 6.3-mm ready-made Parietene Ventral Patch (Medtronic) was used.

Results

161 patients (104 in PR and 57 in SR groups) were included in the study (22 months follow-up). Nine recurrences were observed [six in PR (5.8%) and three in SR group (5.2%)]. In PR group, three patients (2.9%) reported complaints at rest and none in SR group, while 18 patients (17.3%) in PR group reported pain during exercises and 7 (12.3%) in SR group.

Conclusion

For the smallest umbilical hernias, the use of dense fascia suturing (short-stitch technique) may be an effective alternative to patch repair techniques in patients with no additional risk factors for recurrence. The mesh patch repair method is associated with a significantly higher risk of postsurgical pain. Diastasis recti is a factor favoring umbilical hernia recurrence after both pure tissue repair and patch repair.

Mesh OR Patch for Hernia on Epigastric and Umbilical Sites (MORPHEUS-Trial): The Complete Two-year Follow-up

OBJECTIVE

The objective of this trial was to identify a superior method for umbilical and epigastric hernia repair in terms of complications. Complications such as an extended operation duration, additional use of painkillers, reoperation, infection, seroma, extended wound care, extended hospitalization, and early recurrence were reported according to the Clavien-Dindo grading system.

SUMMARY BACKGROUND DATA

Over the years mesh repair is proven the gold standard for umbilical and epigastric hernias. The question remains, which mesh should be used?

METHODS

In this randomized controlled, multicenter trial, all patients ≥ 18 years with a single, symptomatic, and primary small umbilical or epigastric hernia qualified for inclusion. Flat preperitoneal polypropylene mesh repair was compared with patch repair (PROCEED Ventral Patch) (PVP).

RESULTS

A total of 352 patients were randomized; 348 patients received the intervention (n = 177 PVP vs n = 171 mesh). One out of 4 suffered from any kind of complication within 2 years postoperative (27.6%). A significant difference in complications was seen, in favor of polypropylene mesh repair (P = 0.044, 22.1% mesh vs 32.5% PVP). Reoperation was performed in 19 PVP operated patients (10.7%) versus 7 patients with polypropylene mesh repair (4.0%, P = 0.021).No significant differences were seen in recurrences (n = 13, 8.4% PVP vs n = 6, 4.1% mesh, P = 0.127).

CONCLUSIONS

In small epigastric and small umbilical hernia repair a flat polypropylene mesh repair was associated with a lower complication rate than PVP repair. No differences in recurrence rates were seen. Combining all complications, the preperitoneal positioned flat polypropylene mesh performed better.

Guidelines for treatment of umbilical and epigastric hernias from the European Hernia Society and Americas Hernia Society

BACKGROUND

Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short- and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias.

METHODS

The guideline group consisted of surgeons from Europe and North America including members from the European Hernia Society and the Americas Hernia Society. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists, and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done on 1 May 2018, and updated on 1 February 2019.

RESULTS

Literature reporting specifically on umbilical and epigastric hernias was limited in quantity and quality, resulting in a majority of the recommendations being graded as weak, based on low-quality evidence. The main recommendation was to use mesh for repair of umbilical and epigastric hernias to reduce the recurrence rate. Most umbilical and epigastric hernias may be repaired by an open approach with a preperitoneal flat mesh. A laparoscopic approach may be considered if the hernia defect is large, or if the patient has an increased risk of wound morbidity.

CONCLUSION

This is the first European and American guideline on the treatment of umbilical and epigastric hernias. It is recommended that symptomatic umbilical and epigastric hernias are repaired by an open approach with a preperitoneal flat mesh.

Primary non-complicated midline ventral hernia: is laparoscopic IPOM still a reasonable approach?

PURPOSE

Ventral hernia repair has become a common procedure, but the way in which it is performed still depends on surgeon's skill, experience, and habit. The initial open approach is faced with extensive dissection and a high risk of infection and prolonged hospital stay. To tackle these problems, minimally invasive procedures are gaining interest. Several new techniques are emerging, but laparoscopic intra-peritoneal onlay mesh (IPOM) is still the mainstay for many surgeons. We will discuss why laparoscopic IPOM is still a valuable approach in the treatment of primary non-complicated midline hernias and review the current literature.

METHODS

We performed a literature search across PubMed and MEDLINE using the following search terms: "Laparoscopic hernia repair", "Ventral hernia repair" and "Primary ventral hernia". Articles corresponding to these search terms were individually reviewed by the primary author and selected on relevance.

CONCLUSION

Laparoscopic IPOM still is a good approach for the efficient treatment of primary non-complicated midline hernias. Several techniques are emerging, but are faced with increased costs, technical difficulties, and low study patient volume. Further research is warranted to show superiority and applicability of these new techniques over laparoscopic IPOM, but until then laparoscopic IPOM should remain the go-to technique.

Open ventral hernia repair with a composite ventral patch - final results of a multicenter prospective study

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).

Severe complications after mesh migration following abdominal hernial repair: report of two cases and review of literature

Background: Migration of mesh after ventral and incisional hernia repair is a rare but well described complication. The aim of our work is to present two cases of mesh migration after incisional hernia repair and to review the current literature.

Methods: We describe the two cases of mesh migration that occurred at our department. Additionally, we performed a systematic literature search.

Results: In both cases we observed a mesh migration with formation of an entero-cutaneous fistula that required surgical therapy. In the literature search we found a total of 16 publications dealing with mesh migration after incisional (n=14) and ventral hernia (n=2) repair in adult patients (15 case reports and one retrospective study). In 9 out of 15 patients (54%) who presented with mesh migration or erosion, a polypropylene mesh was responsible for this complication.

Conclusions: Mesh migration after abdominal hernia repair is rare, the only available retrospective study reports a rate of 2.7%. The ability of polypropylene mesh to migrate into hollow viscera is well known and confirmed both by our data and the results of the literature review. As the incidence of mesh erosion/migration is significantly lower than the recurrence rate after hernia repair without mesh, up to now, no better alternative exists for the treatment of abdominal wall hernia than mesh augmentation.

Incarcerated Femoral Hernia Repair with Ventralex™ Hernia Patch through Same Skin Incision and Suprainguinal Laparotomy

Purpose

To report our experience with incarcerated femoral hernia procedure, which allows laparotomy through same inguinal skin incision, inspection and resection of compromised bowel, and preperitoneal tension-free transabdominal repair with Ventralex™ Hernia Patch.

Materials and Methods

The suprainguinal laparotomy was performed via same groin incision without compromising iliopubic tract. The femoral ring was sealed with Ventralex™ Hernia Patch pulled through the abdominal cavity and secured outside. Five consecutive patients diagnosed with incarcerated femoral hernias were operated. All of them required laparotomy, either for bowel resection (n = 3) or for inspection of viability (n = 2).

Results

All patients tolerated the procedure well. There were no wound or mesh infections, incisional hernias, or recurrences during follow-up.

Conclusions

Our easy-to-master operative approach to incarcerated femoral hernia allows easy access to abdominal cavity through same groin incision without compromising iliopubic tract or midline laparotomy. Reduction of incarcerated bowel and its inspection and resection can be safely performed. The femoral ring defect can be effectively obliterated with Ventralex™ Hernia Patch.

Retrospective analysis of smaller than 3-cm umbilical hernia repair with the lightweight macroporous mesh

There is evidence that mesh repair for primary umbilical hernias results in fewer recurrences and similar wound complication rates compared to tissue repair. Various devices and surgical approaches are used in umbilical hernia repair. The ULTRAPRO PLUG (UPP) has been adopted for inguinal hernias and femoral hernias with excellent results. However, there are few reports on the use of UPP for umbilical hernia repair. Thus, the aim of this study was to evaluate efficacy and safety in the treatment of smaller than 3-cm umbilical hernias using the UPP.The medical records of 123 patients who underwent umbilical hernia repair using the UPP between October 2011 and September 2017 were reviewed. All patients were followed-up after 1 month and later in 2018. Demographics, surgical information, and immediate postoperative and long-term complications were assessed.Out of 123 patients, there were 37 male and 86 female patients with a mean age of 50.6 years. The median duration of hernia surgery was 20.5 min (range, 12-34), and 109 (88.6%) patients underwent day surgery. The median defect diameter was 1.4 cm (range, 0.5-3). No mortality or major complications occurred during the perioperative period. Long-term follow-up data were available for 107 (87.0%) patients. The median follow-up duration was 33 months (range, 5-76 months). Early postoperative complications included 1 case of seroma, 2 cases of fat liquefaction, and 1 case of superficial surgical site infection. During follow-up, there were 2 recurrences, 1 case of chronic mesh infection, and 2 patients with chronic postoperative pain.The ULTRAPRO PLUG offers a simple and quick means of repairing smaller than 3-cm umbilical hernias with lower recurrence rates and fewer postoperative complications.

Measuring Success in Complex Abdominal Wall Reconstruction: The Role of Validated Outcome Scales

BACKGROUND

Diminished quality of life (QOL) often drives patients to hernia repair, and patient-reported outcomes have gained importance in hernia research. Functional outcomes provide a patient-centered evaluation of a treatment, and improved QOL is a desired outcome assessing treatment effectiveness.

METHODS

Properties of validated QOL measure are reviewed and distinctions between generic and disease-specific measures are discussed. Based on a review of the literature, current validated outcome scales are evaluated and compared.

RESULTS

Currently, there is little agreement over the best means to measure QOL. As a result, several measures have been created, focusing on several distinct aspects of QOL. While generic measures provide global assessments, disease-specific measures report changes as they relate to the hernia itself and hernia surgery. With the introduction of new QOL measures, it is important to understand the properties of a good QOL measure.

CONCLUSIONS

Several questions remain unanswered regarding QOL, including which measures best assess hernia patients, what is the ideal time to evaluate QOL, and for how long postoperatively should QOL be measured. The introduction of guidelines to address these issues may enable improvement in value assessment.

Infection and recurrence rates of the C-QUR V-Patch™ in ventral hernia repairs

PURPOSE

Ventral hernias are a common surgical issue and a myriad of surgical mesh designs has been developed for their treatment. Many of these new mesh designs have not been extensively tested and their complications rates are largely unknown. The C-QUR V-Patch Mesh^™ combines a unique knit construction polypropylene mesh with an omega-3 fatty acid coating. There has only previously been one reported study investigating this mesh.

METHODS

A multicentre cohort study, with a single surgeon, of 168 consecutive patients with ventral hernias underwent repair using a standardized open pre-peritoneal approach with the novel C-QUR V-Patch Mesh^™ between January 2013 and June 2015. A median follow-up of 37 months was completed to assess the patients for hernia infection and recurrence rates. Mesh infections were further classified into early and late infections for further subgroup analysis.

RESULTS

Infection and recurrence rates of the C-QUR V-Patch^® were compared with similar published results of alternate mesh designs. Surgical site infection rates were 7.7% and recurrence rates were 2.4%. The infection rate rose dramatically to 19.0% when the mesh was placed intra-peritoneally. The rate of mesh explantation was 2.4% and usually occurred between 4 and 12 months post-operatively. Smoking was the only factor that appeared to be associated with recurrence.

CONCLUSION

This series finds that recurrence rates associated with the novel C-QUR V-Patch Mesh^™ is acceptably low; however, infection rates appear to be higher when compared to comparable products for use in ventral hernia repairs.

Mesh versus suture repair of umbilical hernia in adults: a randomised, double-blind, controlled, multicentre trial

BACKGROUND

Both mesh and suture repair are used for the treatment of umbilical hernias, but for smaller umbilical hernias (diameter 1-4 cm) there is little evidence whether mesh repair would be beneficial. In this study we aimed to investigate whether use of a mesh was better in reducing recurrence compared with suture repair for smaller umbilical hernias.

METHODS

We did a randomised, double-blind, controlled multicentre trial in 12 hospitals (nine in the Netherlands, two in Germany, and one in Italy). Eligible participants were adults aged at least 18 years with a primary umbilical hernia of diameter 1-4 cm, and were randomly assigned (1:1) intraoperatively to either suture repair or mesh repair. In the first 3 years of the inclusion period, blocked randomisation (of non-specified size) was achieved by an envelope randomisation system; after this time computer-generated randomisation was introduced. Patients, investigators, and analysts were masked to the allocated treatment, and participants were stratified by hernia size (1-2 cm and >2-4 cm). At study initiation, all surgeons were invited to training sessions to ensure they used the same standardised techniques for suture repair or mesh repair. Patients underwent physical examinations at 2 weeks, and 3, 12, and 24-30 months after the operation. The primary outcome was the rate of recurrences of the umbilical hernia after 24 months assessed in the modified intention-to-treat population by physical examination and, in case of any doubt, abdominal ultrasound. This trial is registered with ClinicalTrials.gov, number NCT00789230.

FINDINGS

Between June 21, 2006, and April 16, 2014, we randomly assigned 300 patients, 150 to mesh repair and 150 to suture repair. The median follow-up was 25·1 months (IQR 15·5-33·4). After a maximum follow-up of 30 months, there were fewer recurrences in the mesh group than in the suture group (six [4%] in 146 patients vs 17 [12%] in 138 patients; 2-year actuarial estimates of recurrence 3·6% [95% CI 1·4-9·4] vs 11·4% (6·8-18·9); p=0·01, hazard ratio 0·31, 95% CI 0·12-0·80, corresponding to a number needed to treat of 12·8). The most common postoperative complications were seroma (one [<1%] in the suture group vs five [3%] in the mesh group), haematoma (two [1%] vs three [2%]), and wound infection (one [<1%] vs three [2%]). There were no anaesthetic complications or postoperative deaths.

INTERPRETATION

This is the first study showing high level evidence for mesh repair in patients with small hernias of diameter 1-4 cm. Hence we suggest mesh repair should be used for operations on all patients with an umbilical hernia of this size.

The results of expanded-polytetrafluoroethylene mesh repair in difficult abdominal wall defects

BACKGROUND

The repair of difficult abdominal wall defects (AWDs) continues to be a crucial and demanding issue for surgeons. This study aimed to present the risk factors and the long-term results of usage of an expanded-polytetrafluoroethylene (e-PTFE) synthetic mesh for the AWR of difficult abdominal wall defects.

METHODS

This study included 156 adult patients who underwent difficult AWR with e-PTFE mesh for incisional hernia, ventral hernia, and created AWDs of various etiopathologies. The association between the risk factors and the postoperative complications of AWR was analyzed, and overall long-term outcomes of e-PTFE repair were assessed.

RESULTS

The median follow-up duration was 119.1 (ranging from 2 to 206) months. In 70 (44.8%) patients, there were major co-morbidities. A surgical site infection developed in 17 (10.9%) patients. Of these, only 2 (1.3%) patients had e-PTFE mesh infection. Seven (4.4%) patients experienced recurrence. Recalcitrant seroma formation occurred in 8 (36.3%) patients.

CONCLUSION

E-PTFE synthetic mesh usage for difficult abdominal wall hernias can help the hernia surgeon obtain safe and durable long-term results of sound repair.

Prospective Analysis of Epigastric, Umbilical, and Small Incisional Hernia Repair Using the Modified Kugel Oval Patch

The study was performed to determine the complication and recurrence rate using the modified Kugel oval patch for small ventral hernia repair. Another aim of the study was to find risk factors for recurrence in patients with this repair. Seventy-three patients underwent ventral hernia repair with the modified Kugel oval patch between April 2013 and February 2015. Prospective follow-up data (18 months postoperative) were collected and evaluated. A total of 58 primary (18 epigastric/40 umbilical) and 15 incisional ventral hernias were repaired with the modified Kugel oval patch (7.6/10.2 cm/8 x 12 cm). We found three patients suffered superficial wound infection and two participants got hernia recurrence. Placement of mesh was found to be a significant risk factor for hernia recurrence. Small ventral hernia repair using the modified Kugel oval patch is a novel and useful approach and we recommend placing the patch preperitoneally.

A multicenter prospective study of patients undergoing open ventral hernia repair with intraperitoneal positioning using the monofilament polyester composite ventral patch: interim results of the PANACEA study

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.

Identifying Effectors of Outcomes in Patients with Large Umbilical Hernias

Quality of life (QOL) has become an important focus of hernia repair outcomes. This study aims to identify factors which lead to ideal outcomes (asymptomatic and without recurrence) in large umbilical hernias (defect size ≥9 cm2). Review of the prospective International Hernia Mesh Registry was performed. The Carolinas Comfort Scale was used to measure QOL at 1-, 6-, and 12-month follow-up. Demographics, operative details, complications, and QOL data were evaluated using standard statistical methods. Forty-four large umbilical hernia repairs were analyzed. Demographics included: average age 53.6 ± 12.0 and body mass index 34.9 ± 7.2 kg/m2. The mean defect size was 21.7 ± 16.9 cm2, and 72.7 per cent were performed laparoscopically. Complications included hematoma (2.3%), seroma (12.6%), and recurrence (9.1%). Follow-up and ideal outcomes were one month = 28.2 per cent, six months = 42.9 per cent, one year = 55.6 per cent. All patients who remained symptomatic at one and two years were significantly symptomatic before surgery. Symptomatic preoperative activity limitation was a significant predictor of nonideal outcomes at one year ( P = 0.02). Symptomatic preoperative pain was associated with nonideal outcomes at one year, though the difference was not statistically significant ( P = 0.06). Operative technique, mesh choice, and fixation technique did not impact recurrence or QOL. Repair of umbilical hernia with defects ≥9 cm2 had a surprising low rate of ideal outcomes (asymptomatic and no recurrence). All patients with nonideal long-term outcomes had preoperative pain and activity limitations. These data may suggest that umbilical hernia should be repaired when they are small and asymptomatic.

Current Trends in Laparoscopic Ventral Hernia Repair

Background and Objectives:

The purpose of this study was to analyze the surgical technique, postoperative complications, and possible recurrence after laparoscopic ventral hernia repair (LVHR) in comparison with open ventral hernia repair (OVHR), based on the international literature.

Database:

A Medline search of the current English literature was performed using the terms laparoscopic ventral hernia repair and incisional hernia repair.

Conclusions:

LVHR is a safe alternative to the open method, with the main advantages being minimal postoperative pain, shorter recovery, and decreased wound and mesh infections. Incidental enterotomy can be avoided by using a meticulous technique and sharp dissection to avoid thermal injury.

Outcomes of 157 V-Patch™ Implants in the Repair of Umbilical, Epigastric, and Incisional Hernias

Umbilical, epigastric, and incisional hernias have traditionally been repaired using a Mayo or tensioned suture technique, with recurrence rates of approximately 50 per cent. Recent studies have shown that a tension-free repair using mesh can drastically decrease recurrence rates. Reinforced deployment prostheses are preferred because they enable retrofascial placement through a small incision, thus avoiding the potential morbidity of a larger incision and the costs associated with a laparoscopic approach. A retrospective chart review was performed of all umbilical, epigastric and incisional hernias repaired with V-Patch, a reinforced deployment prosthesis, by a single surgeon. Data analysis included patient characteristics, operative and postoperative metrics, hernia recurrence, and complication rates. Between 2009 and 2012, 157 implantations were performed in 152 patients during 156 procedures. Patient age ranged from 20 to 85 (mean 48). There were 88 females (57.9%) and 64 males (42.1%) with average body mass index of 30.6. Patch size distribution was 78 small (49.7%), 55 medium (35.0%), and 24 large (15.3%). There were 81 umbilical hernias (51.6%), 36 epigastric hernias (22.9%), 39 incisional hernias (24.8%), and 1 multiple recurrent inguinal hernia (0.6%) repaired. Follow-up time ranged from 18 months to 4.3 years. There were six hernia recurrences (3.2%). Complications included three patients (1.9%) with mesh infection, one with an enterocutaneous fistula (0.6%), and one patient with a postoperative small bowel obstruction (0.6%). Four patients required patch explantation (2.5%). The V-Patch reinforced deployment prosthesis is effective in the treatment of umbilical, epigastric, and incisional hernias, and has a low rate of complications.

Repair of Small and Medium Size Umbilical Hernias with the “Proceed Ventral Patch” in the Preperitoneal Position

Small- and medium-sized ventral hernias including umbilical hernias can be repaired using prosthetic patches placed in the peritoneum. However, bowel-associated complications secondary to intraperitoneally placed hernia patches have been reported. Herein, we report the outcome of small and medium umbilical hernia closure with prosthetic hernia patches in the preperitoneal space. Prospectively collected data of patients undergoing repair of small- and medium-sized umbilical hernias with the proceed ventral patch in a primary care hospital in Germany was retrospectively analyzed. A total of 39 cases, including 11 female and 28 male patients, were managed with prosthetic patches in the preperitoneal position. Small-sized patches were implantated in 16 cases, whereas medium-sized patches were used in 23 cases. The median duration of surgery was 40 minutes. The median length of hospital stay was four days. Four minor complications were recorded (10.3%) and the rate of recurrence was 2.6 per cent within a follow-up period of up to 30 months. Small and medium size umbilical hernias can be effectively closed with prosthetic patches placed in the preperitoneal space without risk of serious bowel associated complications.

Cost-utility analysis of repair of reducible ventral hernia

BACKGROUND

Patient-reported outcomes are an important metric of the effectiveness of care. Ventral hernia repair is a procedure where the effectiveness can best be quantified using health-related quality of life. This study sought to quantify quality of life with respect to costs of ventral hernia repair.

METHODS

This observational study of patients diagnosed with a ventral hernia between 2004-2011 in a single center identified 3 groups of patients: (1) Patients diagnosed with ventral hernias managed with observation, (2) patients diagnosed with ventral hernias who underwent operative repair only when incarceration occurred, and (3) patients with ventral hernias who underwent herniorraphy before incarceration. The Short Form (SF)12v2 was administered to measure quality of life. The direct costs of care were obtained from Financial Services. Patients were surveyed about direct, non-health costs to obtain a societal perspective. A cost-utility analysis was performed.

RESULTS

The SF-12v2 was administered to 243 patients; 80 were observed, 69 underwent repair of an incarcerated hernia, and 94 underwent repair of a nonincarcerated hernia. The response rates were similar among groups-59%, 55%, and 52%. Quality of life as measured by utility score was less at 0.68 (95% CI, 0.65-0.71) in patients who did not undergo repair compared with those after repair of a nonincarcerated hernia, 0.76 (95% CI, 0.73-0.79; P < .001). The elective repair of a nonincarcerated hernia was cost-effective with an incremental cost effectiveness ratio of $8,646 per quality-adjusted life-year.

CONCLUSION

The prompt elective repair of ventral hernias is cost-effective.

Standardized measurement of quality of life after incisional hernia repair: a systematic review

BACKGROUND

Recent improvements in incisional hernia repair have led to lower rates of recurrence. As a consequence, increasing attention has been paid to patient-reported outcomes after surgery. However, there is no consensus on how to measure patients' quality of life after incisional hernia repair. The aim of this systematic review was to analyze existing standardized methods to measure quality of life after incisional hernia repair.

DATA SOURCES

A PubMed and Embase search was carried out together with a cross-reference search of eligible papers, giving a total of 26 included studies.

CONCLUSIONS

Different standardized methods for measurement of quality of life after incisional hernia repair are available, but no consensus on the optimal method, timing, or length of follow-up exist. International guidelines could help standardization, enabling better comparison between studies.

Repair of umbilical and epigastric hernias

Umbilical and epigastric hernias are primary midline defects that are present in up to 50% of the population. In the United States, only about 1% of the population carries this specific diagnosis, and only about 11% of these are repaired. Repair is aimed at symptoms relief or prevention, and the patient's goals and expectations should be explicitly identified and aligned with the health care team. This article details some relevant and interesting anatomic issues, reviews existing data, and highlights some common and important surgical techniques. Emphasis is placed on a patient-centered approach to the repair of umbilical and epigastric hernias.

A Collective Review on Mesh-Based Repair of Umbilical and Epigastric Hernias

In accordance with the tension-free principles for other hernias, umbilical and epigastric hernia repair should probably be mesh-based. The number of randomized studies is increasing, most of them showing significantly less recurrences with the use of a mesh. Different devices are available and are applicable by several approaches. The objective of this review was to evaluate recent literature for the different types of mesh for umbilical and epigastric hernia repair and recurrences after mesh repair. A multi-database search was conducted to reveal relevant studies since 2001 reporting mesh-based repair of primary umbilical/epigastric hernia and their outcomes in adult patients. A total of 20 studies were included, 15 of them solely involved umbilical hernias, whereas the remaining studies included epigastric hernias as well. A median of 124 patients (range, 17-384) was investigated per study. Three quarters of the included studies had a follow-up of at least 2 years. Six studies described the results of laparoscopic approach, of which one reported a recurrence rate of 2.7 %; in the remaining studies, no recurrences occurred. Two comparative studies reported a lower incidence of complications and postoperative pain after laparoscopic repair compared to open repair. Seventeen studies reported results of open techniques, of which seven studies showed no recurrence. Other studies reported recurrence rates up to 3.1 %. A wide range of complication rates were reported (0-33 %). This collective review showed acceptable recurrence rates for mesh-based umbilical and epigastric hernia repair. A wide range of devices was investigated. A tendency toward more complications after laparoscopic repair was found compared to open repair.

What would surgeons like from materials scientists?

Surgery involves the repair, resection, replacement, or improvement of body parts and functions and in numerous ways, surgery should be considered human engineering. There are many areas in which surgical materials could be improved, but surgeons are generally unaware of materials available for use, while materials scientists do not know what surgeons require. This article will review some of the areas where surgeons and materials scientists have interacted in the past and will discuss some of the most pressing problems which remain to be solved. These include better implant materials for hernia repair, breast reconstruction, the treatment of diabetes, vascular stenting and reconstruction, and electrical pacing devices. The combination of tissue engineering and nanomaterials has great potential for application to nearly every aspect of surgery. Tissue engineering will allow cells or artificial organs to be grown for specific uses while nanotechnology will help to ensure maximal biocompatibility. Biosensors will be combined with improved electrodes and pacing devices to control impaired neurological functions.
