Active clinical trials for "Hernia, Inguinal"

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symphysis, and the camera itself, if used as dissection device, would become smudged and it would have to be repeatedly withdrawn for cleaning.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.

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.

Investigation of the correlation between the success of obtaining unilateral spinal anesthesia and the measurement of perfusion index (pi).

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 aim of the project is to show that gene expression levels change in at least one of the GATA6 and T-box transcription factor 3 (TBX3) genes in indirect inguinal hernia sacs, thus revealing that this pathway causes an error in the sac closure pathway. Indirect inguinal hernia is an important condition for human health as it is common in the community and can lead to life-threatening or permanent loss of function. In addition, since the treatment is performed surgically, the follow-up and treatment process of the patients should be managed carefully in terms of complications and costs. By explaining the mechanisms of the occurrence of this disease, important steps will be taken in terms of both human health and the development of science. Moreover, the data to be collected may open new horizons in the treatment of inguinal hernia. 20 inguinal hernia patients those consecutively applied to Trakya University Medical Faculty Department of Pediatric Surgery and 20 circumcision patients as control group will be included in the study.

this study has the aim to analize the correlation between three different methods of mesh fixation ( using absorbable or non absorbable sutures or fibrin biological glue) and recurrance and chronic pain ,in the Lichtenstein anterior inguinal erniorrhaphy

The use of synthetic mesh plugs for open inguinal hernia repair has seen dramatic variability in the number and composition of meshes currently on the world market. The use of biomaterials (PLLA, PGA) in hernia mesh is a relatively new and innovative method. These selected polymers have the ability to degrade while implanted, allowing for sufficient natural tissue healing and scarring. This usage presumably favors a decrease in foreignness, inflammatory reaction, recurrence, and incidence of chronic groin pain. Prior studies with similar plug meshes in the same indication have yielded favorable results which require this mesh to be investigated in its specific application. Primary Objective Evaluate the incidence of peri-operative and post-operative complications after the application of the Parietex plug and patch hernia system in open inguinal hernia repair. We will assess the efficacy of this mesh by examination and the application of a pain scale at the following intervals: 1 month, 3 months, and 1 year, respectively. Assessment is intended to evaluate: Patient report of pain via their Pain score Wound complication Incidence of chronic groin pain Recurrence rate Other complications Secondary Objectives Record the description and assessment of the Parietex plug and patch hernia system: surgical technique description of dissection and mesh placement method of fixation operative times, anesthesia choice length of hospital stay mesh handling characteristics return to daily activities overall patient satisfaction

Animal studies showed that many general anesthetics might result in neuron apoptosis and neurocognitive impairment in the developing brain. However results from human studies are conflicted. In present study, the investigators examined the association between early exposure to anesthesia and surgery for minor surgery and intelligence changes in adolescence using the Wechsler Intelligence Scale for Children.

Patients scheduled to undergo laparoscopic preperitoneal or open inguinal hernia repair will be evaluated by means of scrotal/testicular ecocolordoppler ultrasound investigation before and after surgery in order to rule out the potential impact of the surgical procedure on testicular arterial and venous blood flow
