What the experts said
Patent processus vaginalis may close spontaneously - Ponsky reports having a patient with documented PPV on initial laparoscopy that was absent on second laparoscopy for unrelated indication
Risk of anesthesia is now so low that bringing a child back for delayed hernia repair after PPV discovery is acceptable
Laparoscopic hernia repair in adolescents may reduce pain compared to open repair because the groin is a very nerve-dense area
When insufflating a distended abdomen for bowel obstruction, waiting 5-10 minutes allows bowel loops to spread out and improve visualization
Open preemie hernia repairs may be causing floor injuries leading to direct hernias that present in adulthood
Ponsky reports never having re-operated on a hernia recurrence in 20 years except for his first seal technique case
Ponsky reports having had maybe 2 hydroceles after laparoscopic repair in 20 years, both of which resolved spontaneously
In rabbit model, suture repair alone showed 25% remained closed at 2 weeks after suture removal, while injury plus suture showed 90% closed at 2 weeks and 100% at 4 weeks
In rabbit suture material study, Vicryl had 80% failure rate, Prolene 75% failure, and silk 10% failure after suture removal
Braided suture works better than monofilament for hernia repair based on rabbit studies
In neonates, Ponsky uses single ligation rather than double because of risk of suture granuloma and spitting due to short distance from skin to knot
Ponsky uses 3-0 Ethibond (braided non-absorbable suture) for the final hernia repair after threading with Prolene
Study of adolescent high ligation (ages 13-18) showed 2% recurrence rate overall, only 0.9% confirmed recurrence at 2-year follow-up
Statistical analysis of adult and pediatric hernia types suggests age 40 may be inflection point where direct hernias become more common, though most remain indirect
Direct inguinal hernias in children are rare findings, making it difficult for pediatric surgeons to maintain proficiency in their repair
Rombaldi reports no hydroceles or scrotal complications from leaving the sac in place during laparoscopic repair
Contralateral PPV is present 30-40% of the time according to Witt's 1994 paper
Risk of metachronous hernia after unilateral repair is 3-11%
In rabbit studies, grabbing the vas deferens in a preemie-sized vessel just once can obliterate it and cause scarring
Ben Zendejas' 50-year follow-up study at Mayo showed some evidence of infertility after childhood inguinal hernia repair
In a study of 8500 patients at fertility clinic, 6% had prior inguinal hernioplasty and their semen quality was markedly reduced compared to fertile men
Risk of hernia incarceration is high in preemies but drops to 1-3% after 1 year of age and less than 1% each year thereafter
The most common recurrence after indirect inguinal hernia repair is a direct hernia, not another indirect hernia
Kaiser study of 1700 children showed recurrence rate of 0.9% for laparoscopic unilateral hernias, with 0.8% for open and 0.3% for laparoscopic
Montreal group published 10% recurrence rate with laparoscopic repair, significantly higher than other centers reporting less than 1%
Felix Shear's studies showed no impediment to cord blood flow after laparoscopic hernia repair
Norwegian mentorship program for adult laparoscopic high ligation reported zero recurrences
VA cooperative study showed chronic pain after mesh hernia repair as high as 30%
Incidence of chronic pain after mesh repair is substantial, and mesh can migrate
Recent adult surgery paper comparing huge scrotal hernias found no difference in complications between resecting versus abandoning the hernia sac
