NCT02328352

Brief Summary

Nanotechnologies applied to General Surgery and Emergency Surgery: The Buckypaper as a new fixing method for prosthetic materials in the treatment of abdominal wall hernias in humans, in laparotomic procedures and as a new device for the treatment of solid cancer and hematopoietic system tumors. The experimentation on this new material, preliminary conducted on breed female rabbit New Zeeland, will be applicable to human, if the results in terms of toxicity and durability will be comfortable.

Study Arms (4)

BP selfstanding felt

EXPERIMENTAL

laparotomy intervention with the incision of 10 cm navel-pubis will be performed, splaying of the skin and subcutaneous layers, then will be incised the fascia plane, and muscles. Ten rabbits (hereafter defined as BPR1-BPR10) will receive 2x2cm2 samples of BP selfstanding felt in a pocket created between muscular fascia and large muscles of the abdominal wall. V-Loc 180 (ref VLOCL0024, lot. A1D0899)

Procedure: BP selfstanding felt

PP mesh

ACTIVE COMPARATOR

intervention of laparotomy with the incision of 10 cm navel-pubis will be performed, splaying of the skin and subcutaneous layers, then will be incised the fascia plane, and muscles. A 2x2cm2 sample of PP mesh was implanted without stitches into a pocket between large abdominal muscle and abdominal fascia. Other names: V-Loc 180 (ref VLOCL0024, lot. A1D0899) PR Parietene mesh Tyco (ref. PP3030, lot. SIK00587)

Procedure: PP mesh

BP intraperitoneal mesh

EXPERIMENTAL

A surgical scar was performed on the abdominal linea alba and carried out deeply for entering into the abdominal cavity. In five rabbits (BPR21-BPR25). A 2x2cm2 BP intraperitoneal mesh was then be inserted with the rough side facing the parietal peritoneum surface and the smooth and brilliant surface facing to the visceral peritoneum and gut.

Procedure: BP intraperitoneal mesh

control group

ACTIVE COMPARATOR

Five rabbits (R26-R30) will be used as control group.

Procedure: control group

Interventions
