Active clinical trials for "Hernia"

Randomized clinical trial comparing open preperitoneal mesh, retromuscular mesh and suture repair for ventral hernias less than 3 cm diameter

We propose to examine Congenital Diaphragmatic Hernia (CDH) patients for evidence of airway inflammation as a first step to characterize the reported bronchodilator responsiveness. Airway biopsy studies are invasive and thus we propose to perform induced sputum studies to document the amount and type of inflammation present. Another ancillary non-invasive measure of airway inflammation that we will use is exhaled nitric oxide (NO). The primary objective of this study is to determine if CDH patients have any evidence of airway inflammation. The hypothesis of this study is that children with CDH do not have evidence of airway inflammation associated with bronchodilator responsiveness. Based on this information, treatment for CDH patients will hopefully be more accurate and appropriate for their specific needs.

A clinical study evaluating acute and chronic pain following laparoscopic inguinal hernia repair comparing the ProGripTM self- fixating mesh with tack fixation.

Congenital diaphragmatic hernia (CDH) has an incidence of 1:2200 to 1:4000 newborns. The survival rate depends on the extent of the lung hypoplasia and pulmonary hypertension. In case of an observed / expected total fetal lung volume ratio (o/e TFLV) ratio of 25% or lower and herniation of the liver in thorax, the postnatal survival is estimated to be 10-25% or lower. The aim of fetoscopic tracheal balloon occlusion is to positively influence the lung growth in CDH fetuses avoiding the development of lung hypoplasia. Some complications after sucsessfull FETO before delivery occur because of technical difficulties during the extraction of the balloon from the trachea, leading to asphyxia, worse outcome or neonatal demise. Jani et al. published 10 neonatal deaths from 210 FETO directly related to difficulties with the removal of the intratracheal balloon. The risk of emergent balloon removal was published to be very high (39%-56%). Our new technique exploits the fetal ability to removal the intratracheal balloon which has been implanted for the treatment of severe CDH before the delivery, avoiding many risks associated with balloon extraction and a second fetoscopy. The study will be performed on 20 fetuses with severe CDH. Before the FETO the total fetal lung volume ratio (o/e TFLV) will be measured by fetal MRI (magnetic . Only CDH fetuses with 24-32 weeks' gestation with o/e TFLV < 25% or the fetuses with o/e TFLV < 35% and liver herniation will be operated Second fetal MRI should be performed in one week after the FETO. The balloon will be extracted by the fetus itself before the delivery, after puncture with 22 gauge needle under ultrasound guiding, during second fetoscopy or using the EXIT (ex utero intrapartum Treatment). Neonatal follow up 12 months.

Aim of the study is to evaluate the risk reduction of intraperitoneal mesh-implementation after laparotomy (Group 1) in a randomized control trial compared with patients with standard abdominal closure (Everett-suture). This is the primary endpoint. Second endpoints are the feasibility of mesh-implementation even after colorectal surgery, find risk factors for wound infection and incisional hernia.

Randomized, controlled, prospective study of 54 patients receiving surgery for cancer of the lower third of the rectum with a permanent end colostomy. The aim of the study was to reduce parastomal hernia (PH) occurrence by implanting a lightweight mesh in the sublay position. Patients were followed up a) clinically and b) radiologically by means of abdominal CT. In the clinical follow-up, hernias were observed in four out of 27 patients (14.8%) in the study group and in eleven out of 27 (40.7%) in the control group (p=0.03). The implantation of the mesh reduces the appearance of PH, is well tolerated, and does not increase morbidity

The trial compares the postoperative complain, pain, quality of life after the implantation of a heavy-weight alternative light-weight mesh, by randomly allocating patients with inguinal hernia disease to two groups of surgeons, each group being trained to operate with one of the above mentioned meshes. Hypothesis: There is less postoperative pain after the implantation of a light-weight mesh.

Parastomal hernias are randomised to either a conventional stoma formed through the rectus anterior muscle or to the same procedure with the addition of a prophylactic mesh in a sublay position.

Design of a simple blind randomized controlled trial study. Large incisional hernia repair with use of local hemostatic Hemoblock

Trocar site hernia is a specific complication of laparoscopic surgery. The increasingly frequent use of the laparoscopic approach has resulted in an increase in the number of hernias, mainly at the umbilical area. The appearance of a trocar site hernia can cause complications in the short and long term to the patient who may end up needing a reoperation. In this study we want to compare the supraumbilical versus the infraumbilical location of the laparoscopy entry trocar, in terms of incisional hernia incidence.
