Intraperitoneal Polypropylene Light Weight Wide Pore Soft Mesh Repair for Complex Ventral Hernia.

Ventral Hernia Clinical Trial

Official title: Intraperitoneal Polypropylene Light Weight Wide Pore Soft Mesh Versus A. Double Mesh Intraperitoneal Repair for Complex Ventral Hernia: A Prospective Randomized Cohort Study.

Status Completed

Clinical Trial Summary

Complex ventral hernia is a challenging problem well known to be associated with occurrence of serious complications. The major problems encountered in such cases Include: loss of domain with subsequent increase of intra-abdominal pressure after repair, the huge musculo-fascial defect and skin scarring with possible skin viability problem resulting from the dissection of skin flaps. There is no unified accepted evidence-based approach for its repair and is attended with a high recurrence rate that may reach up to 67%. In a previous study using the ADMIR technique of intraperitoneal repair and after a long-term follow-up the investigator was able to reduce the recurrence rate to 4% after an average follow up period of 142 months. In the current study the investigator will use the same technique of intraperitoneal mesh repair comparing the polypropylene light weight, wide pore, soft mesh with a double mesh using the same polypropylene mesh and a vicryl mesh as a protective layer against the bowel. If it is proven as effective as the mesh with protective layer and with no increased risk of morbidity, this will result in marked reduction of the cost of treatment by nearly 90 % and will abolish the waiting list of patients as the polypropylene mesh is readily available.

Clinical Trial Description

According to randomization policy, patients' will be allocated to two groups each one will include 30 subjects: Group I (the study group) in which the investigator will use a polypropylene wide pore soft mesh (Bard, USA). Group II (the control group) in which the investigator will use the same polypropylene mesh in association with Vicryl mesh (Polyglactin 910, VM95, Ethicon, Belgium). The mesh will be prepared by suturing the Vicryl and polypropylene mesh together after folding the edges (2 cm each) and its fixation with four full thickness corners Vicryl 2/0 stay sutures. Another four sutures anchoring the overlapped edges together will be applied at the center of each edge, after that, the mesh will be inserted intraperitoneally in an oblong fashion in defects above the point midway between the umbilicus and symphysis pubis and in horizontal fashion in defects in the hypogastric region with the Vicryl part facing the bowel. U sutures using polypropylene 0 will be applied through the whole thickness of the anterior abdominal wall in order to anchor the four angles of the mesh. Then, the turned over edges of the mesh will be fixed to the inner aspect of the abdominal wall using interrupted full thickness U sutures or mesh stapler (fascia stapler, Medtronic (covidien), USA) according to availability. The same technique will be used in the study group excluding the vicryl mesh. Following mesh fixation, a tailored viable part of the sac will be closed over the mesh to separate it from the subcutaneous tissue in order to minimize seroma formation. Follow-up data will be recorded in a proforma for each patient, noting intraoperative and postoperative complications and postoperative hospital-stay. Each patient will be examined by the surgical team in the Outpatient Clinic at postoperative days 7, 15, and 30 to assess early complications, and at 3 months for one year and every 6 months for 2 years, to assess late complications when necessary after making the scheduled telephone communication. ;
