A Retrospective Nationwide Comparison of Laparoscopic vs Open Inguinal Hernia Repair in Children
A nationwide study examined over 53,000 children who had inguinal hernia repair across the United States.
host_summaryLizzie Lee0:06 ↗
Approximately 16% of pediatric inguinal hernia repairs in the study were performed laparoscopically.
host_summaryLizzie Lee0:13 ↗
The majority of pediatric inguinal hernia repairs in the study were open repairs.
host_summaryLizzie Lee0:15 ↗
Laparoscopic inguinal hernia repair had more than 3 times the risk of same-side recurrence compared to open surgery.
host_summaryLizzie Lee0:23 ↗
Laparoscopic inguinal hernia repair was linked to fewer future surgeries on the opposite side (metachronous hernias).
host_summaryLizzie Lee0:30 ↗
The findings comparing laparoscopic and open inguinal hernia repair held up after adjusting for hospital differences and patient factors.
host_summaryLizzie Lee0:36 ↗
Open inguinal hernia repair has a lower risk of same-side recurrence compared to laparoscopic repair.
host_summaryLizzie Lee0:40 ↗
Laparoscopic inguinal hernia repair may reduce the chance of needing surgery on the contralateral side.

host_summaryLizzie Lee0:13 ↗
The majority of pediatric inguinal hernia repairs in the study were open repairs.
host_summaryLizzie Lee0:15 ↗
The study compared two key outcomes: hernia recurrence on the same side and the need for a second hernia operation later on.
host_summaryLizzie Lee0:17 ↗
Laparoscopic inguinal hernia repair had more than 3 times the risk of same-side recurrence compared to open surgery.
host_summaryLizzie Lee0:23 ↗
Laparoscopic inguinal hernia repair was linked to fewer future surgeries on the opposite side (metachronous hernias).
host_summaryLizzie Lee0:30 ↗
The findings comparing laparoscopic and open inguinal hernia repair held up even after adjusting for hospital differences and patient factors.
host_summaryLizzie Lee0:36 ↗
Open inguinal hernia repair has a lower risk of same-side recurrence compared to laparoscopic repair.
host_summaryLizzie Lee0:40 ↗
Laparoscopic inguinal hernia repair may reduce the chance of needing surgery on the contralateral side.

BOB Ped Surg 2023 - Christina Theodorou, CAPS - Presentation
In cases of large congenital diaphragmatic hernia defects, diaphragmatic replacements are used, most commonly synthetic patches such as PTFE or Gore-Tex.
clinicalChristina Theodorou0:00 ↗
Synthetic patches for diaphragmatic hernia repair are associated with significant morbidity including hernia recurrence, bowel obstructions, and chest wall deformities as the child grows.
clinicalChristina Theodorou0:00 ↗
The ideal diaphragm replacement would integrate with native tissue, mechanically match the function of the diaphragm and allow for growth with the child.
opinionChristina Theodorou0:00 ↗
Biodegradable forms of polyurethane have been used in tissue repair recently such as vascular and muscular tissue replacement and have high mechanical strength.
clinicalChristina Theodorou1:00 ↗
The study created 4 mm diaphragmatic defects in rats followed by immediate patch repair, with cohorts of six animals each plus a sham cohort of six rats.
clinicalChristina Theodorou1:00 ↗
Animals were survived for four weeks with fluoroscopic evaluation of diaphragmatic excursion at one and four weeks post-op.
clinicalChristina Theodorou1:00 ↗
No recurrences were seen in either the polyurethane or Gore-Tex cohort at four weeks.
clinicalChristina Theodorou2:00 ↗
At one week post-op, there was no difference in diaphragmatic excursion between sham, Gore-Tex, and polyurethane animals.
clinicalChristina Theodorou2:00 ↗
At four weeks, Gore-Tex had limited diaphragm rise compared to sham, but no difference was found between polyurethane and sham.
clinicalChristina Theodorou2:00 ↗
There were no differences in diaphragmatic excursion between polyurethane and Gore-Tex at any time point.
clinicalChristina Theodorou2:00 ↗
An inflammatory capsule was formed surrounding both polyurethane and Gore-Tex patches.
clinicalChristina Theodorou3:00 ↗
There was no significant difference in the size of the inflammatory capsule between the polyurethane and Gore-Tex cohorts.
clinicalChristina Theodorou3:00 ↗
The study had small numbers of animals in each cohort (six per group), likely under powering detection of significant differences.
