Mesh and Mesh Fixation in Laparoscopic Groin Hernia Surgery

2018-12-03 00:02:25 | BioPortfolio


The study attempts to quantify the relative risks for recurrence depending on complex combinations of plausible risk factors, in particular mesh, mesh fixation, hernia size and hernia type.

For this purpose the investigators will analyze data from the Swedish Hernia Registry (SHR).


This is an open cohort study design where the investigators will analyze existing data that have been prospectively collected in the Swedish Hernia Registry (SHR), which covers about 98% of all groin hernia repairs in Sweden. The very large cohort of more than 37,000 TEP and TAPP repairs enables assessment of the relative risks for recurrence depending on complex combinations of plausible risk factors, in particular mesh, mesh fixation, hernia size and hernia type, with fulfilling statistical power.

Each participant was entered at the date of surgery, when demographic and intraoperative data were registered. The SHR mandates that each surgical unit subsequently reports the occurrence or absence of complications during the first 30 days. Reoperations were registered in the SHR in the same manner as index repairs, and were used as endpoints.

Medical and Biotech [MESH] Definitions

An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.

A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.

A groin hernia occurring inferior to the inguinal ligament and medial to the FEMORAL VEIN and FEMORAL ARTERY. The femoral hernia sac has a small neck but may enlarge considerably when it enters the subcutaneous tissue of the thigh. It is caused by defects in the ABDOMINAL WALL.

The tunnel in the lower anterior ABDOMINAL WALL through which the SPERMATIC CORD, in the male; ROUND LIGAMENT, in the female; nerves; and vessels pass. Its internal end is at the deep inguinal ring and its external end is at the superficial inguinal ring.

A pelvic hernia through the obturator foramen, a large aperture in the hip bone normally covered by a membrane. Obturator hernia can lead to intestinal incarceration and INTESTINAL OBSTRUCTION.
