1. LAPAROSCOPIC INGUINAL HERNIA REPAIR Jeffrey S. Bender, MD, FACSUniversity of OklahomaCollege of Medicine
2. Objectives Appreciate the history and evolution
Understand the various approaches
Have knowledge of the complications and outcomes
Not an attempt to teach how
3. Inguinal Hernia – The Problem Very common
Recurrence rates still as high as 15%
Increased recognition that mesh necessary
“Tension-free” repairs
4. Laparoscopic Hernia Second most common laparoscopic procedure
Initial enthusiasm now tempered
Technically more difficult than laparoscopic cholecystectomy
Patient demand not as great
5. History First performed with clips 1979 (Ger)
Didn’t become popular until laparoscopic cholecystectomy
Initial series (1990) reported plug only
Plug migration a problem: fixation
6. History (cont) Plug: recurrence rate of 25%
Realization that patch necessary
Recognition of defect in transversalis fascia
Three currently used techniques
7. Transabdominal Preperitoneal Herniorrhaphy (TAPP) First reported 1991
Closure of peritoneum required
Easier to learn
Risk of bowel injury
8. Intraperitoneal Onlay Mesh Herniorrhaphy (IPOM) First reported 1992
Technically the easiest (no retro-peritoneal dissection)
Anecdotal: adhesion of bowel to mesh
Not a problem in only large series published
9. Totally Extraperitoneal Herniorrhaphy (TEPP) First reported 1993
Similar to Stoppa technique
Avoid bowel injuries
Learning curve reportedly more difficult
10. Early Results 444 repairs in 375 patients, 1991-1994
Mostly TEPP; single surgeon
Recurrence rate 0.7%
Overall complication rate 2.0%
Two operations for SBO Fielding Aust NZ J Surg, 1995
11. 869 hernias in 686 patients, 1991-1992
ľ TAPP, Ľ IPOM, multi-institutional
Recurrence rate 4.5%
Overall complication rate 17.1%
One bowel perforation, one bladder injury, one SBO Fitzgibbons, et al. Ann Surg, 1995 Early Results
12. 600 repairs in 493 patients, 1991-1994
˝ TAPP, ˝ TEPP, single institution
Recurrence rate 1.2% (TAPP > TEPP)
Overall complication rate 2.0%
3 bowel injuries, 2 bladder injuries, 1 SBO (port) Ramshaw, et al. Surg Endosc, 1996 Early Results
13. Effective repair
Probable shorter convalescence
No long term data
Serious complications in 2-4:1000 Summary of Early Results
14. Randomized Trial #1 487 TEPP vs. 507 open, 1994-1995
One year follow-up
6 wound infections open vs. 0 in TEPP (p=0.03)
TEPP had quicker recovery, back to work, etc.
15. Recurrence: 6.0% open vs. 3.0% TEPP (p=0.05)
24 conversions to open operation in laparoscopic group
7 major hemorrhage in laparoscopic group vs. 2in open group
Open operation not standardized (only 3% had mesh)
Liem, et al.
NEJM, 1997 Randomized Trial #1
16. 496 laparoscopic vs. 460 open
One year follow-up
Complications: 29.9% lap vs. 43.5% open (p=.001)
Return to activity: 10 days lap vs. 14 days open (p=.004) Randomized Trial #2
17. Persistent groin pain: 28.7% lap vs. 36.7%open (p=.018)
Recurrence: 1.9% lap vs. 0.0% open (p=.017)
3 major complications in laparoscopic group MRC Group Lancet, 1999 Randomized Trial #2
18. 989 laparoscopic (90% TEPP) vs. 994 open, 1999-2001
Two year follow-up
Complications: 39.0% lap vs. 33.4% open
2 port site hernias, 2 major bleeds in laparoscopic group Randomized Trial #3
19. 3 deaths in laparoscopic group (1 bowel injury)
1 death in open group
Return to activity: 4 days lap vs. 5 days open
Laparoscopic had less pain Randomized Trial #3
20. Primary recurrence: 10.1% lap vs. 4.0% open
Recurrent recurrence: 10.0% lap vs. 14.1% open, p=n.s.
250 lap hernias necessary to reduce recurrence rate
Open recurrence rate not altered by experience Neumayer et al.
NEJM, 2004
Randomized Trial #3
21. Summary Laparoscopic herniorrhaphy likely less painful
Short term outcomes comparable
Long term outcomes unknown
Small, but real serious complication rate
Experience is key
22. Current Practice Discuss, but don’t propose for primary
Good option for recurrent (especially early) or bilateral
Possible advantage in obese
High index of suspicion for complications
