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.

Proper Surgical Treatment of Small and Medium Size Umbilical Hernias. A Single Surgeon Experience

Introduction: Minimally invasive surgical procedures have become routine interventions nowadays and represent an effective therapeutic option even for small umbilical hernias, providing favorable postoperative and aesthetic results.

Aim of study: To determine the most appropriate minimally invasive treatment option for small and medium size umbilical hernias.

Materials and methods: We conducted a prospective study on 50 patients with small or medium umbilical hernia (<4 cm). All patients benefited of minimal invasive surgery with mesh implantation. Depending on the surgical procedure, two major groups were defined: group A – patients with open surgical approach (n = 24) and group B – patients undergoing laparoscopic surgery (n = 26). Clinical, surgical, postoperative, and follow-up data were analyzed.

Results: Mesh replacement via open approach through the umbilicus was associated with significantly reduced surgical time (p = 0.0359), administration of painkillers (p = 0.0461), and use of anticoagulants (p = 0.0404). Hospital stays (p = 0.0001) and costs (p = 0.0005) were also significantly lower in this group. After 6 months of follow-up, no recurrence was observed, and no significant differences were detected regarding postoperative pain and the patients’ professional reintegration. Patient satisfaction regarding postoperative scar was superior in the open group.

Conclusion: The present study indicates that the ventral patch technique is a safe and effective method for the treatment of small and medium size umbilical hernias.

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.

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.

Risk of recurrence following mesh associated incisional hernia repair using the retromuscular technique in patients with relevant medical conditions

BACKGROUND

Incisional hernia is a common problem following open abdominal surgery. Hernia repair in patients with relevant medical conditions is a topic of controversy due to the high risk of morbidity and recurrence. We investigated the risk of recurrence in patients with relevant medical conditions managed with a prosthesis in the retromuscular position.

METHODS

A retrospective review of the data of patients undergoing midline incisional hernia repair was performed. The outcomes of patients with relevant concomitant medical conditions defined as ASA scores >2 were compared with those of healthier patients with ASA scores ≤2.

RESULTS

115 patients including 41 with ASA >2 and 74 with ASA ≤2 were included for analysis. There were no statistically significant differences amongst both groups with regard to the size of the hernia defect, the duration of surgery (123.0 ± 71 vs. 149.0 ± 92 min, p = 0.73), the incidence of postoperative seroma (14.6% vs. 29.7%, p = 0.07), postoperative hematoma (12.2% vs. 4.1%, p = 0.10) and surgical site infection (14.6% vs. 8.1%, p = 0.27). No statistically significant difference was seen amongst both groups with respect to the rate of long-term recurrence after a median follow-up of 63.0 ± 36 months (12.2% vs. 6.8%, p = 0.32).

CONCLUSION

Relevant medical condition alone cannot be seen as a contraindication for midline incisional hernia repair using the retromuscular technique. Rates of morbidity and long-term recurrence following mesh-associated closure are not difference from those of healthier patients.
