INTRODUCTION: Gastric perforation is a rare occurrence, particularly in neonates. This is an emergency case in this population. The incidence of spontaneous gastric perforation in neonates is 1:2900 live births, with high mortality and morbidity rates. The primary treatment is surgical debridement and repair of the perforation, which has a high incidence of anastomotic leakage. At present, there is a plethora of studies investigating the efficacy of human dried amniotic membrane (H-DAM) technology in promoting wound healing. Consequently, researchers sought to ascertain whether there were differences in the number of adhesion and abscess classifications for the macroscopic evaluation of gastric perforation repair with HDAM as a biomaterial in New Zealand white rabbits.
MATERIAL AND METHODS: A total of 30 male New Zealand rabbits underwent laparotomy and gastric perforation. These animals were then divided into three groups, with each group comprising 10 rabbits. Group 1 underwent primary repair, group 2 underwent omental patch repair, and group 3 underwent H-DAM patch repair. The rabbits were euthanised on the 7th day and the adhesion score and abscess classification were evaluated.
RESULT: A total of 30 samples of rabbits were homogeneous. On macroscopic evaluation, it was found that the H-DAM had the lowest mean adhesion score and the lowest incidence of abscess formation compared to all other groups.
CONCLUSIONS: It can be concluded that the utilisation of HDAM as a biomaterial patch in the treatment of gastric perforation in the rabbit model did not result in any instances of leakage, adhesion or infection.
