Filter by:Short-term follow up after surgery of para-esophageal hernia comparing two different types of fundoplication
This study evaluates the effect of anterior gastropexy (one or more sutures fixing the stomach to the inner abdominal wall) on improving durability of paraesophageal hernia repair. Half of participants will receive anterior gastropexy, while the other half will not. The hypothesis is that anterior gastropexy will help to prevent paraesophageal hernias from recurring.
This is a prospective, case-matched, systematic follow up of up to 70 pre-existing patients whom underwent paraesophageal hernia repair between June 1, 2012 and September 30, 2016. Patients whom are willing to participate in the study will be asked to return for a one time follow up visit to reassess for hiatal hernia recurrence both symptomatically and radiologically to compare the efficacy of the use of MatriStem Surgical Matrix (ACell) mesh to other biologic meshes.
To study the long term outcome of Laparoscopic Hiatal Hernia Repair with human acellular dermal matrix Alloderm (LifeCell, Branchburg, NJ) mesh.
Surgical therapy for gastroesophageal reflux disease (GERD) and hiatal hernia (HH) can achieve outcomes that afford the patient lifelong satisfaction. The published results obtained with this surgery may not be considered to be definitive in relation to the length of follow-up or patients' life expectancy. The real recurrence rates and the results of surgery for GERD are difficult to assess due to the lack of serial time points during the follow-up. Further bias may have been introduced into the analysis by a lack of appropriate controls. The results of surgical therapy for type II-IV HH are even more controversial because of the high rate of anatomical relapse and the different methods of follow-up adopted in reported case series. Aim of this study is to clarify the value of surgical therapy for type II-IV HH. The investigators report on patients who were followed up after surgery at various time points over the course of 30 years.
Background: The existence, diagnosis and treatment of short esophagus is one of the controversies of the past which has recently re-emerged. The missed diagnosis of short esophagus and the consequent inadequacy of treatment is one of the major causes of failure of antireflux surgery. The daily clinical practice of surgeons dedicated to therapy of esophageal diseases could take advantage of the definition of frequency, preoperative predictors, intraoperative management and post operative outcomes of cases of foreshortened esophagus, in order to offer the patient affected by GERD the elements necessary for a conscious choice of therapy and to plan the best performance of the surgical procedure. Aims of the Study To define the percentage of cases among the total of antireflux procedures performed for type II-IV hiatus hernia, in which, after standard isolation of the ge junction and dissection of the mediastinal esophagus at least two centimetres of esophagus can not be replaced without any applied tension below the apex of the diaphragmatic hiatus.
The study will examine potential biological and genetic mechanisms leading to hiatal and paraesophageal hernia formation in predisposed individuals. It is expected that these patients will have defects in the normal production and maturation of collagen and other connective tissue proteins, thus leading to weakness in the diaphragm that may allow for spontaneous herniation. Comparison of tissue and blood samples from these patients (study group) will be made to those from individuals undergoing lower esophageal surgery who have not developed a concurrent hernia (i.e. esophageal myotomy for achalasia and laparoscopic gastric bypass or laparoscopic adjustable gastric banding for morbid obesity - control group).
The purpose of this randomized study is to determine whether a type of mesh derived from a layer of pig small intestine (SIS) is of benefit in treating paraesophageal hernias versus standard surgical suture repair.
