Active clinical trials for "Hernia"

Incisional hernia is a common condition after abdominal surgery. Because linea alba has less vascularity, incisional hernia more common in midline incisions. It is seen in the general population between 11-20%. In some high-risk situations, this rate increases up to 40-69% (abdominal aortic aneurysm, morbid obesity, colorectal surgery).It is known that incisional hernia that occurs in the postoperative period can lead to emergency surgical causes such as incarceration-strangulation, has a significant share in health expenses and seriously impairs the quality of life in patients.One of the methods tried to reduce incisional hernia is the use of mesh. But this abdominal closure technique is not used routinely in our country and the other countries. This study will be important of the studies in Turkey and world for patient selection in prophylactic mesh use, techniques to be applied and early / late results. The aim of the study is to compare the classical abdominal closure technique with use of mesh in order to minimize the incisional hernia and associated complications after midline laparotomy.

Congenital diaphragmatic hernia (CDH) is associated high mortality and morbidity, mainly in those cases with severe forms where there are extremely reduced lung volumes, liver herniation and decreased abnormal pulmonary vascularization. Fetal endoscopic tracheal occlusion performed between 26 and 30 weeks (standard FETO) has been shown to increase fetal pulmonary size and vascularity, and to improve infant survival in isolated severe CDH. Fetal pulmonary response followed FETO can be used to predict outcome and is dependent on the size of the fetal lung prior to the procedure. We hypothesize that performing an earlier FETO, between 22-24 weeks, fetuses with severe form of CDH will have a better fetal pulmonary response and higher chance of surviving.

The investigators describe a new surgical technique for inguinal hernia open repair, which will be compared with the Lichtenstein technique. The investigators seek to find the difference between the two techniques in postoperative pain.

The neonatal mortality rate in cases with severe isolated congenital diaphragmatic hernia is higher than 90% due to severe pulmonary hypoplasia. Many studies have suggested that fetal tracheal occlusion may increase lung volumes and therefore reducing the risk for severe pulmonary hypoplasia and by consequence the risk for neonatal death. The main objective of the present study is to evaluate if fetal tracheal occlusion improves survival rate in those cases that are followed in our hospital, by conducing a randomized trial.

Inguinal hernia repair is one of the most frequently performed operations in young men. Persistent pain after inguinal surgery represents a significant cause of disability, occurring in between 15%-35% of cases. In a majority of these patients, their groin pain persisted after a previous hernia repair. The main type of chronic postsurgical pain is neuropathic, caused by injured nerves. One of the principal components in the pathophysiology of postsurgical pain is cytokines, specifically tumor necrosis factor (TNF). In animal studies, injecting TNF inhibitors before nerve injury can reduce pain behaviors and neuropathology. Finding a way to reduce the incidence of postsurgical pain after hernia repair could enhance function, and reduce the need for opioids and other analgesics. The investigators intend to conduct the first randomized, controlled study evaluating whether preemptive administration of a tumor necrosis inhibitor can reduce postoperative pain and opioid consumption after hernia repair. This is important because the degree and intensity of postsurgical pain is a major predictor for the development of chronic postsurgical pain.

The aim of this study was to analyze the shrinkage of two different screens in the repair of inguinal hernias in men . 32 patients with unilateral inguinal hernia were assigned randomly. A Lichtenstein tension-free hernia repair was accomplished by emplacing heavy weight versus ultralight weight polypropylene meshes for repair of incisional hernia, marked next to the lips with six titanium clips (LT200).

The purpose of this study is to: compare the long term results of mesh versus suture repair in treatment of abdominal wall defects; find the optimal location of implanted prosthesis, comparing the two most useful position of mesh in abdominal wall hernia surgery.

Background: Midline incisional hernia is reported from 0,5 to 11% after abdominal operations. Primary repair without mesh reinforcement is almost abandoned because of high recurrence rates (24 to 46%). Use of prosthetic mesh in incisional hernia repair lowered the recurrence rates under 10%. Recurrence rate alone is not the main quality criterion for incisional hernia repair anymore. Large series and meta-analyses confirmed the value of laparoscopic repair as at least equal if not better compared with open repair. Discomfort, pain, diminished quality of life and body image alteration influences functional well being. No baseline information exists in any of these fields treating pre- or post-operative phases in patients with incisional hernia. Respiratory functions and medico-economic evaluation are other rarely investigated fields that we consider in our trial. The objective of this study is to analyse the functional outcome status of patients after laparoscopic incisional hernia repair compared to open repair. Methods: A randomized controlled non-blinded clinical trial is designed to compare laparoscopic incisional hernia mesh repair with open repair on post operative pain, health related quality of life outcomes, body image and cosmetic measurements, respiratory functions, recurrence rates, and cost. Volunteers will be recruited in Geneva University Hospital, department of surgery, visceral surgery unit. Eligibility criteria is male patient aged over 18 years, with reducible incisional hernia who are candidates for elective surgery and medically fit for general anesthesia.30 patients will be enrolled for each group. Follow-up will take place at 10th, 30th days as well as 3 12 and 24 post operative months by questionnaires and by clinical exam by independent expert. An overall cost-analysis will be realized. Patient enrollment in the study will start in April 2008 and estimated to end in september 2009.

Left diaphragmatic hernia detected during fetal life carries a high risk for postnatal lung failure due to lung underdevelopment and pulmonary hypertension. In severe cases, extracorporeal membrane oxygenation (ECMO) is used as a life-saving intensive care means to enable survival of severely affected infants. Clinical experience from prospective controlled non-randomized case series with fetoscopic tracheal balloon occlusion has seen improved survival rates in contrast to untreated controls. Therefore, the purpose of this randomized clinical trial in a less severely affected subgroup of patients is whether by fetoscopic tracheal occlusion, the intensity of postnatal intensive care therapy might be reduced. Primary outcome measure is the need for postnatal ECMO therapy.

Aim The general aim of this study is to improve post-operative pain and reduce morphine consumption following laparoscopic ventral hernia repair (LVHR). We specifically aim to conduct a randomized, double blinded, controlled trial to investigate the effect of intra-peritoneal local anaesthesia infusions on post-operative morphine consumption and. Methods: Patients will be randomised by computer generated random numbers (random permutation) and opaque envelope methods. At closure, one small 2mm catheter belonging to the AutoFuser pain pump system will be placed in the peritoneal cavity between the onlay mesh and parietal peritoneum. In the treatment arm patients will receive 275mL of 0.2% ropivacaine at 4mL/h. In the placebo arm, 275mL of 0.9% normal saline will be used in a similar fashion. The infusions will run for 68 hours total. All members involved in patient care (with the exception of one independant research fellow) will be blinded to the above. After 68 hours the pump will be stopped and the catheter will be removed. Assessment of post-operative pain will be performed by visual analogue scale, and total opiate consumption will be collected and converted into morphine equivalents. Health significance: Local anaesthesia has become an important addition to multimodal regimens of analgesia following surgery. Recent studies have shown that local anaesthetic (LA) wound infiltration has improved post-operative pain when compared with standard opioid regimens for pain relief. Only one previous study looked at bupivacaine infusions into the hernia sac for three days following LVHR. This study found no improvement in post-operative pain or morphine consumption. We aim to demonstrate improved pain and reduced morphine consumption using an alternative catheter insertion technique and ropivacaine as the desired LA agent.
