Strengths and weaknesses of laparoscopic and open mesh inguinal hernia repair: a randomized controlled experimental study

Abstract

There are no objective data available on the relative strengths of inguinal hernia repairs. The aim of this randomized controlled study was to measure th force required to disrupt laparoscopic and open mesh repairs in a porcine model. Eleven pigs had inguinal hernia repair following randomization to an open mesh group (n = 5) or a transabdominal preperitoneal laparoscopic group (n = 6). Four weeks after operation the pigs were killed and the pelvic girdles were mounted in a test jig on a mechanical testing machine. The applied disruption forces were measured and recorded. Mean(s.d.) force required to disrupt the normal inguinal canal (n = 11) was 68.6(30.1) N with no difference between groups. The open mesh repair required 110.3(41.4) N and the laparoscopic mesh 220.0(95.2) N. Both open and laparoscopic mesh repairs were stronger than the normal side (P < 0.03). The laparoscopic mesh repair was stronger than the open mesh repair (P = 0.04). This model provides a standardized method for mechanically testing inguinal hernia repairs in pigs. It confirms that both open and laparoscopic mesh hernia repairs are stronger than the non-herniated normal side at 4 weeks after operation. Laparoscopic mesh repair is stronger than open mesh ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
