Tailored Approach to Hernia Repair
HEAD score does not take obesity into account.

Pre-operative collagen testing?
Abnormal collagen metabolism in primary inguinal and incisional hernia formation 1 .
Collagen I/III ratio is altered by Type III collagen and Type I collagen 2 .
Would pre-op skin testing lead us to the “right” repair and thus reduce recurrence?
Can we modify collagen ratio with pre-op medications?

Role of the Surgeon in Recurrence Does Choice of Operation Affect Recurrence?
Examination of literature demonstrates no difference in recurrence rates when comparing Lap to Open tension free mesh repairs 4 .
VA study supports open over laparoscopic repair for primary hernias 5 .
TAPP vs. TEP
Recent Meta-analysis gives no indication that one technique is superior 6 .

Learning Curve in Laparoscopic Hernia Repair
The more you do the better you are.
How many cases required to be proficient?
30-50 cases as suggested by Davis et al 7
250 cases as suggested by Neumayer et al 8
Difficult to apply magic number concept to individual surgeons.

Role of the Surgeon in Recurrence
Answer to prolonged learning curve?
Surgeon Education 10,11,12
Mastery of open preperitoneal repair first?
Cadaveric/Animal based courses?
Intensive, prolonged mentoring by experienced surgeon?
Referral of patients to high volume specialty centers? 9

“ Other Causes of Recurrence?”
Lau et al . describe a 7.2% seroma formation rate in TEP. Seromas resolved spontaneously at a mean of 2.4 months and did not influence recurrence rate 27 .
Choy et al . performed TEP with 15 X 15 cm mesh followed by desufflation, repetitive hip flexion and re-examination of the mesh. In no case did the mesh migrate 28 .
Early strenuous activity?
Bay-Nielson et al . demonstrated no difference in early recurrence rate between patients advised to take a short convalescence ( 1 day) versus a long convalescence 29 .
