4. Why laparoscopy: Ifs, ifs and ifs!
Bilateral: up to 10%??
Cosmesis??
Recovery??
Vasal injury??
Vessel injury??
Recurrence???

5. Why laparoscopic hernia repair?
Major problem with Laparoscopic hernia repair (LHR) is recurrence
A main concern is the increased recurrence rate after LHR (up to 6%)
Recurrence study: Felix Schier
The largest series of recurrences after LHR
The intent is to define the problem of recurrence

6. But! Lesser dissection Contralateral repair Smaller incision
Detect other types of hernia
A chance to suture??

7. Anatomy of relevance

8. Criticisms Not backed by enough statistical evidence!
Level I Evidence is lacking
Have not defined less experienced surgeon clearly!
After how many herniotomies?
Open vs Lap hernia: Remains a debate

15. Future: Non suture hernia repair?

18. Facts! Age: <6 years- Thinner tissue Side: Immaterial
Gender: Boys- Fear of injury to vas and vessels
Experience: No recurrence in last 200 cases, F Schier
Medial recurrence are more common: Due to incomplete closure
due to fear of injury to Inferior epigastric vessels

19. Recurrence: Other studies
451 LHR in 314 children of various ages in our institution from September 2002 to September 2006.
Technical improvements:
(1) decreasing tension on the purse-string knot
(2) using an airtight knot
(3) stress-testing the airtightness of the knot by increasing intraperitoneal gas pressure

Hydroceles are considered as complications and not as recurrences.
How are they treated- With herniotomy?
Isn’t a small opening a recurrence?
Our experience: 2/56, 3.57%
Hydrocele 1: Sclerotherapy with 1% Setrol
Hydrocele 2: Sclerotherapy failed, needed herniotomy

23. Reason for hydrocele

24. Personal communication: Felix Schier
FS: This is unusual. We have only very rarely a hydrocele. It believe it was just bad luck. Lymphatic occlusion I do not believe, because we would see hydroceles far more often if that would be the case. I have no suggestion on how to prevent this.

Abstract
INTRODUCTION:
Abdominoscrotal hydroceles (ASH) represent a difficult surgical problem in which a large scrotal hydrocele extends through the inguinal canal into the intraabdominal, extraperitoneal space, creating a widened internal ring that may be associated with an inguinal hernia.
SUBJECTS AND METHODS:
Patients with ASH were repaired using a combined laparoscopic-inguinal approach. Laparoscopic exploration was used to confirm the diagnosis, rule out associated hernia, assess for contralateral pathology, and confirm adequate peritoneal closure at the level of the internal ring, after a standard inguinal approach was used to repair the ASH.
RESULTS:
Eight patients are described with a median age of 13 months. One patient presented with bilateral ASH, and 5 patients had contralateral pathology, including simple hydrocele (n=3), undescended testicle (n=1), and inguinal hernia (n=2). Three patients were confirmed to have an ipsilateral inguinal hernia associated with their ASH. Postoperative complications included hematoma (n=2) and recurrent hydrocele (n=1). No patient developed ipsilateral or contralateral hernias following ASH repair (median follow-up, 3.2 years).
CONCLUSIONS:
Although laparoscopy is not essential, we have found it to be a useful adjunct to ensure accurate diagnosis and repair of abdominoscrotal hydroceles in children.

32. Take home message
Acceptable recurrence rate in pediatric hernia repair should be <1%
Laparoscopic hernia repair:
watertight tension free repair
Medial stitch is most important
Smaller children are more prone for recurrence
Hydroceles are unavoidable???
Open hernia still a valid option!
