Active clinical trials for "Hernia"

MRI imaging in clinically evident inguinal hernia is not routinely used. In other painful inguinal conditions (such as sportsmans hernia) inflammatory changes have been detected. The aim of the present study is to determine, whether similar inflammatory changes can be detected with MRI scan in inguinal hernia. Also, patient questionaires are used preoperatively and postoperatively to determine, if preoperative pain scores can be used as a predictive value for postoperative prolonged pain/neuralgia.

Watchful waiting is non-inferior to surgical repair of asymptomatic and oligosymptomatic incisional hernias in terms of pain and discomfort during normal activities.

Knowing that the risk of stoma associated herniation (parastomal or incisional) is 30-50% and the associated morbidity significant, standard placement of a prophylactic mesh upon stoma creation might prevent parastomal (or incisional herniation, after closure) and improve the quality of life of a large group of patients. This study is meant to be a pilot study to see whether the mesh related risks of infection and adhesion morbidity are acceptable if the mesh is placed intraperitoneally.

The purpose of this study is to assess the early outcomes when using the Biomerix Revive™ as a tension-free onlay patch, Lichtenstein-style, in patients who are candidates for primary, unilateral, open inguinal hernia repair.

This study is being done to evaluate the use of a material (Alloderm collagen mesh) during the stomal formation operation (surgery that will create a mouth-like opening on the surface of the body to an internal organ). The main purpose of this research study is to see if using this material will lower the hernia rate compared to normal repair without this material. The secondary purpose is to evaluate if using this material will increase or decrease complication rates.

Purpose of study is to assess perioperative functional parameters of the anterior abdominal wall muscles and postural control status in patients with large and giant incisional hernias in a controlled diagnostic study. The study involved 95 patients (100% completed) with a large or giant incisional hernia of the anterior abdominal wall. The participants were divided into three groups by type of hernia repair: bridged hernia repair, Rives-Stoppa procedure, or TAR technique. Perioperative functional parameters of the anterior abdominal wall muscles were assessed by tension dynamometry. The postural balance assessments were made by raster photostereography.

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.

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.
