Active clinical trials for "Hernia"

Acutely symptomatic abdominal wall hernia can cause many symptoms and complications. They can be associated with levels of morbidity beyond that seen in emergency laparotomy. There is limited data to guide practice in this field. This observational cohort study will explore variation in practice around assessment, repair and outcomes of hernias treated in the emergency setting.

Evaluate the outcome of micro endoscopic discectomy (MED) by tubular retractors on safety and efficacy of the technique.

Ventral hernias, such as umbilical, epigastric and trocar-site hernias, are best repaired with abdominal wall reinforcement by mesh implantation. Mesh-devices using a dual-sided mesh technology have been developed for the specific indication of small ventral hernias; this technique is very attractive because the mesh can be introduced through a nearly invisible scar in the umbilicus. The dual layer of the mesh inhibits the formation of adhesions of the viscera to the mesh so, if wanted, it can be positioned in a intraperitoneal position. No literature is available on the adequate size of mesh needed to repair a hernia defect of an umbilical or epigastric hernia. Very small hernias are now often enlarged for repair with a large mesh device. Small hernias might benefit of repair with a small mesh device so no enlargement of the defect is necessary Larger hernias might benefit from a larger mesh size to have more overlap of the mesh beyond the hernia defect. The SITUP-trial was a prospective cohort study who was designed to explore the efficacy of C-QUR V-Patch of different sizes for the different sizes of hernia defects. The study was stopped prematurely because of the perception of an unacceptably high rate of mesh infection. This new study will retrospectively examine the incidence of mesh infection in all ventral hernias repaired with a C-QUR V-Patch. Collection of patient data was done using the Eura-HS registry.

Our recent prospective randomized controlled study comparing single-port vs. multiport laparoscopic total extraperitoneal inguinal herniorraphy (NCT 01660048) demonstrated superiority of the single-port technique in reducing post-op pain/analgesic requirements, quicker return to work/normal physical activities and improved cosmetic scar scores. During this study all patients underwent the initial extraperitoneal dissection with the distension balloon. However, the balloon itself costs AU $380 per device which represents a significant percentage of the overall cost of the procedure (when the hospital/operating rooms cost is approximately AU $2500 for a unilateral laparoscopic inguinal hernia repair) especially if only unilateral inguinal herniorraphy is performed. The European Hernia Society Guidelines encourage the use of the distension balloon for the initial distension/dissection of the extraperitoneal space especially during the learning curve. This recommendation arises from the fact that during the conventional multiport repair the umbilical port allows only the insertion of the laparoscope and the extraperitoneal space cannot easily be dissected with the scope itself, especially in patients with well-developed linea alba extending down to the pubic symphysis, and the camera itself, if used as dissection device, would become smudged and it would have to be repeatedly withdrawn for cleaning. Yet this must occur since the extraperitoneal space must be dissected in the midline sufficiently for safe insertion of two additional 5 mm ports for insertion of dissecting instruments in order to complete the extraperitoneal space dissection and the repair. With single incision laparoscopic surgery the use of the Triport™ system ensure that the port can be place under direct vision into the extraperitoneal space when the scope and two dissecting instruments can be safely inserted at the outset. In this way the extraperitoneal space can be dissected under direct vision. The balloon dissection is essentially a blind dissection even though the balloon distension is being observed by the scope, incorrect tissue planes can be entered ie the dissection can occur below the pre-peritoneal fascia exposing the nerves in the groin with the potential risks for nerve damage and entrapment. This is an argument that surgeons who practise transabdominal preperitoneal inguinal hernia repair use to justify their superior technique over the TEP repair because, in the TAPP repair, the peritoneum is carefully dissected free from and leaving the underlying preperitoneal fascia intact. While the use of the balloon, when some 25 "pumps" of air are used during the insufflation, to create a significant space to place not only the two 5 mm ports but also to create a significant extraperitoneal dissection when usually only the lateral space and the hernia sac need to be dissected this is not always possible. In patients who have had previous lower abdominal surgery including previous anterior inguinal herniorraphy (especially if the mesh plug is used) the balloon dissention is normally judicious as one cannot predict whether there are any significant peritoneal or even bowel adhesions. Consequently, in such cases, the balloon distension is normally confined to an area just inferior to the umbilical port and superior to the pubic symphysis so that there is just enough extraperitoneal dissection to place the two 5 mm trocars. Usually this means only using only 5 pumps of air in the distension balloon for placement of two 5 mm trocars. Then the dissection of the extraperitonealy space under direct vision can take place. The use of the distension balloon in such cases represents an enormous waste of resources since AU $380 is spent just to create enough space to place the two 5 mm ports and hence allowing the insertion of the dissecting instruments. With the Triport+™ port the dissecting instruments can easily be placed in the extraperitoneal space and the dissection can begin under direct vision hence achieving the same safe dissection that TAPP surgeons claim to perform. In this study we aim to look at the safety and efficacy of telescopic vs. balloon dissection by prospectively comparing a similar former group of patients to the ones who had previously undergone single-port inguinal herniorraphy with balloon dissection in our previous study (NCT 01660048). All patients having surgical treatment of groin hernia at St Luke's and Holroyd Private Hospitals are subject to very careful assessment and study. All patients are requested to report immediately if there are any problems.

Congenital diaphragmatic hernia (CDH) occurs when the diaphragm, the muscle that separates the chest cavity from the abdominal cavity, does not form properly. When an opening is present in the diaphragm, organs that are normally found in the abdomen can move up into the chest cavity. The primary objective of this study is to generate information about the hereditary basis of congenital diaphragmatic hernia and abnormal lung development. Our long-term goal is to identify ways to treat babies in utero with effective but safe drugs to speed up lung development before birth.

Inguinal hernia is a common disease in children. Treatment of this disease by laparoscopic high ligation of the hernia sac has been accepted by domestic and foreign scholars. Since laparoscopic inguinal hernia was introduced in 1990,it has now become the most commonly performed hernia repair in children. The conventional approach this is done with2small trocars to 1trocar . however the wound complications of infection and pain and the recurrent rate have not been resolved. The aim of the study was to described a new way of extra-peritoneal high ligation of hernia sac. This method combines the single-port laparoscopic could eliminated rate of wound complications and recurrence in inguinal hernia repair in children. The investigators hoped that this study will prove that the extra-peritoneal single-port laparoscopic repair is at least a s effective and efficient as the conventional technique in the cure of inguinal hernia and may results in lower recurrence and reduce incidence of wound complications.

The aim of the study is to evaluate the clinical effects of Discogel® Radiopaque Gelified Ethanol as therapeutic substance for nucleolysis application in the patients with cervical disc hernia who had chronic pain and weakness on the neck, shoulders and arms.

This study will be comparing the patients overall satisfaction of two different meshes used in laparoscopic inguinal hernia repairs.

Outpatient services in Germany are less controlled by external quality assurance programs. Comprehensive outcome data for benchmarking or health-care decision-making are missing e.g. for day case surgery. A quality-of-life instrument specific to hernia repair with mesh has been recently proposed (Carolinas Comfort Scale, CCS) .This study evaluates the integration of CSS as part of a multicentre quality assurance scheme for day-case (outpatient) surgery.b.The Study Group on "Quality assurance in ambulatory hernia surgery" has developed and standardized Operation technique for 3D Implants. As a consequence, any deviation must be documented by the standard. The extension to other centers according to a standardized protocol took place (shadowing to learn the operational standards, training in documentation, Minimum quantity 30 interventions per year, etc.).

The investigators propose a randomized, single blinded controlled trial to compare the use of synthetic versus biologic mesh in hiatal hernia repair, two currently accepted standard of care surgical modalities. The investigators hypothesize that use of synthetic mesh will have lower recurrence at these time points compared to use of biologic mesh.
