Abstract
BACKGROUND
The worldwide accepted repair for indirect inguinal hernia in children is high ligation of the hernia sac with open herniotomy. However, laparoscopic pediatric inguinal hernia repair (IHR) has been gaining popularity in the last two decades. An experimental study was conducted to investigate the effects of different intraperitoneal IHR suture techniques on the collagen formation at the hernia sac neck.
METHODS
Present study was conducted on thirty-five male adult (3-6 months old) Wistar-Albino rats (260-300 g). Intraperitoneal IHR with different hernia sac neck suturing techniques (purse string suture only, transfixation suture only and purse string suture plus transfixation suture) were performed through median laparotomy using open operative techniques. Non-absorbable 2/0 braided polyester suture with 16 mm 1/2 curved round needle (Ti-cron, Covidien, MN) was used as suture material.
RESULTS
The highest collagen thickness around the suture was detected in intraperitoneal IHR with purse-string plus transfixation suture group. The collagen thickness of the intraperitoneal IHR with purse string suture only and IHR with tranfixation suture only groups were not statistically significantly different. The collagen thickness of the intraperitoneal IHR with purse string suture plus transfixation suture group was statistically significantly higher compared with the intraperitoneal IHR with purse string suture only and intraperitoneal IHR with transfixation suture only groups.
CONCLUSIONS
The combined usage of purse string suture and transfixation suture during laparoscopic intraperitoneal inguinal hernia repair further stimulates mesothelial fibrosis at the hernia sac neck compared with mesothelial fibrosis induced by purse string suture only or transfixation suture only.
