Active clinical trials for "Hernia"

Background Laparoscopic cholecystectomy is a very common procedure. Postoperative pain, especially around the umbilical port is dominating the first postoperative week. Single Incision Laparoscopic cholecystectomy (SILC) has been proposed to diminish postoperative incisional pain and improve cosmetic results, but results are not convincing and the risk of formation of an umbilical trocar-site hernia is not properly investigated. This study aimed to investigate the risk of umbilical trocar-site hernia formation after SILC vs. conventional 4-port laparoscopic cholesystectomy. Methods This is a cohort registry study with prospective questionnaire and clinical follow-up on 239 patients having a SILC from 1/1 2009 to 1/6 2011 vs. 478 mathed patients having a conventional laparoscopic cholecystectomy (consecutively from one month before and after SILC. They are matched for age, gender, date of operation, and surgeons skills (database from intraoperatively registered data). Primary endpoint is umbilical trocar-site hernia formation (operation for a umbilical hernia or clinical hernia). The H0 hypothesis is that there is not difference between SILC and conventional. Exclusion criteria are: death, operation for acute cholecystitis. The included patients will be sent a questionnaire asking for operation for a hernia in the area, suspicion of a hernia, and perioperative data that we do not have in the database. Futhermore those patients who suspect a hernia will be invited to aclinical exam by a medic to state the diagnosis. Furthermore we patients are asked to report if they have chronic pain and/or discomfort.

Incisional hernias are one of the most frequent complications in abdominal surgery. Laparoscopic repair is widely used but even not standardized. Existing data from different study designs show no representative data resulting in a lack of comparability and evidence. Therefore the standardization of operative techique has been proposed by the LIPOM-study group and will be assessed in a prospective manner.

Congenital diaphragmatic hernia is an anatomically simple birth defect in which contents of the fetal abdomen migrate into the chest due to incomplete formation of the diaphragm. Herniation of viscera into the chest prevents the fetal lungs from developing and growing to normal size. In the most severe cases, there is significant morbidity and mortality at birth. For these fetuses, fetal intervention may improve outcomes by enabling the lungs to grow enough in utero that they are capable of sustaining life after birth. This unblinded, non-randomized trial will assess the safety and efficacy of the use of the Goldvalve balloon and MiniTorquer microcatheter to perform percutaneous temporary tracheal occlusion to treat severe CDH in utero. The primary outcome variable will be fetal lung growth due to successful 'plugging/unplugging' of the trachea, as determined by serial lung-head ratio (LHR) measurements. Secondary outcome variables include maternal, fetal and neonatal variables, specifically neonatal survival at 90 days of life. For infants who survive beyond 90 days post-delivery, their families will be offered follow-up (up to 2 years of age and possibly beyond) in the Long-term Infant-to-Adult Follow-up Evaluation (LIFE) Clinic at UCSF.

We have been asked to participate in the Pediatric Anesthesia NeuroDevelopmental Assessment Study (PANDAS), which is a study to compare neurocognitive functions in sibling pairs: one of whom had exposure to anesthesia during inguinal hernia surgery before three years of age (exposed) and the other who was not exposed to anesthesia or surgery in the first three years of life (unexposed). A consortium of approximately 6 hospitals is doing this feasibility study to determine if there is an adequate number of subjects for each of the two age groups before the formal study begins.

Combining the advantage of minimally invasive surgery with laparoscopy to reduce postoperative complications and the placement of a retromuscular prosthesis with closure of the defect in order to reduce the risk of adhesion and restore normal anatomy in the treatment of primary and incisional ventral hernias, is made possible through robotic assistance. The challenge of this study concerns the evaluation of quality of life, postoperative pain and recurrence at 6 months in the management of primary and incisional ventral hernias by robot-assisted laparoscopic approach.

The purpose of this study is to measure the changes in tension after each release in a standard posterior component separation during abdominal wall reconstruction.

Nationwide cohort study on women undergoing epigastric hernia repair

We will examine the outcome of ventral hernia repair with subsequent pregnancy

The objective of the Project ADOPT- Ventral Hernia case-series is to collect clinical outcome data following the completion of a hands-on proctorship training model in laparoscopic ventral hernia repair.

The aim of this study is to evaluate risk factors and complications of ventral hernia repair. A retrospective study of journal files with patients undergoing ventral hernia repair, and an analyses of complications by use of the Clavien-Dindo classification of surgical complications.
