Abstract
Summary and conclusion
Inguinal hernia repair remains the most common operation
performed by pediatric surgeons. It occurs in 0.8% to 4.4 % of all
children with higher incidence (up to 30%) in premature babies.
Conventional Open hernia repair is the gold standard for
treatment of PIH. However, it has the potential risk of injury of the
spermatic cord, vas deferens, hematoma, wound infection, iatrogenic
cryptorchidism, testicular atrophy, and recurrence of hernia.
With feasibility and safety of laparoscopy many centers
routinely perform laparoscopic hernia repair in children and there have
been numerous reports describing various laparoscopic techniques
rather than the traditional open approach, because of its advantages
over conventional procedure including magnification, less manipulation
to vas and vessels.
Many techniques were introduced over the last 2 decades for
laparoscopic treatment of inguinal hernia including intracorporeal and
extracorporeal approaches, disconnecting the sac or not and closure of
the peritoneum with different techniques. Recently it was claimed that
disconnection only of the sac was enough laparoscopic treatment of
PIH.
During the period from March 2016 to March 2017 at the
pediatric surgery unit, Tanta University Hospital, 34 patients with 40
PIH with the age ranging from one month to 2 years were categorized
into 2 groups A and B. The categorization was randomly done using a
closed envelop method. group A: contains infants and children who
