Pediatric inguinal hernia: laparoscopic versus open surgery.
OBJECTIVE
Herniotomy/open surgery (OS) has been the time honored treatment for pediatric inguinal hernia (PIH). Laparoscopic surgery (LS) has recently emerged as an alternative in its management. However, controversy is rife on its feasibility and wider adoption. The present need is to know whether a significant difference exists in the surgical outcomes following either technique.


METHODS
In a prospective study between January and December 2006, 85 children underwent either LS (51) or OS (34) for PIH. Operation time, intra- and postoperative complications, postoperative pain, postoperative stay, cosmesis, and the size of testis were recorded and compared for differences in outcome. Patients were followed up for an average of 3.5 months.


RESULTS
All in the open group had unilateral (UL) hernias. The laparoscopy group had 6 (11.8%) bilateral (BL) hernias, and 10 (22.2%) contralateral patencies of processus vaginalis (CPPV) were detected intraoperatively and repaired simultaneously. Bilateral repairs were excluded from comparative analysis. LS was slightly quicker than OS to perform [25.31 min vs 30.65 min (P=0.06)]. The difference in pain perception, between LS and OS, was insignificant. Immediate postoperative recovery was delayed in more children undergoing LS (P=0.02), but the duration of hospital stay was similar (P=0.37). Complication rates were similar (P=0.96). Cosmesis in LS was superior to that in OS.


CONCLUSIONS
Well-performed conventional herniotomy yields results similar to those of laparoscopic repair. Cosmesis and the ability to detect and simultaneously repair CPPV are the 2 main advantages of LS over OS. Keeping in mind the low incidence of meta-chronicity in UL hernias, insignificance of cosmesis over the groin, and the constraints of the developing world, conventional open herniotomy can justly be performed for UL hernias, as the standard of care, in centers lacking laparoscopy.
