Effects of Position and a Test Meal on Esophago-gastric Junction Morphology and Function Assessed...

Hiatus Hernia

Retrospective analysis for HRM measurements using liquid swallows and a test meal for the presence of hiatal hernia. The investigators will correlate hernia descriptions with presence of acidic reflux and clinical complaints.

ACELL Mesh for Paraesophageal Hernia Repair

Paraesophageal Hernia

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.

Foreshortened Esophagus and Its Surgical Therapy

Gastroesophageal Reflux DiseaseHiatal Hernia

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, in which, after standard isolation of the ge junction and eventual 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. To define the percentage of surgical procedures aimed to treat electively a condition of non reducible G-E junction and foreshortened esophagus, among a multicentric formed case series of patients submitted to antireflux surgery. To define the preoperative clinical and instrumental predictors for a surgical procedure aimed to treat foreshortened esophagus. To record the intra-operative, postoperative, 6 month and 12 month outcome of procedures adopted for the surgical treatment of GERD. Materials and Methods The study will comprise patients in which surgical therapy for GERD is indicated according to the international guidelines and the Centres policy . Patients will be submitted to the antireflux procedure chosen by the surgeon according to the internationally recognized scientific surgical principles and the personal judgement. The preoperative study and the postoperative follow up adopted in the present study are accepted by the Centres as they correspond to the international guidelines and the Centres' current practice criteria for the surgical treatment of GERD.

Follow-up of Patients Operated Upon for Type II-IV Hiatal Hernia

Gastroesophageal Reflux Disease With Hiatal HerniaParaesophageal Hernia

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.

Genetic Analysis of Congenital Diaphragmatic Disorders

Congenital Diaphragmatic HerniaCongenital Diaphragmatic Eventration2 more

The purpose of this study is to understand the genetic causes of congenital diaphragmatic disorders (CDD), namely congenital diaphragmatic hernia (CDH), eventration and hiatal hernia. Specifically, the investigators plan to: Ascertain informative families and sporadic cases with congenital diaphragmatic disorders and obtain appropriate phenotypic data and genetic material (peripheral blood and/or diaphragm tissue sample). Localize the gene(s) for CDD to specific chromosomal segments using linkage analysis, and determine the role of somatic mutations in CDD. Isolate and characterize genes involved in the pathogenesis of CDD. Develop molecular markers that will facilitate accurate diagnosis (including prenatal diagnosis) and permit correlation of phenotypic variation with specific mutations. Compare RNA-sequencing from tissue samples of children without CDH to those children with CDH.

Study of Paraesophageal Hernia Repair With Small Intestine Submucosa

Hiatal HerniaParaesophageal Hernia

In 2006 this research group reported their initial findings of a multi-center prospective trial comparing primary repair and primary repair buttressed with a biologic mesh made from porcine small intestinal submucosa (SIS). We were able to accrue 108 patients from 7/2002-3/2005 and followed each patient over 6 months and performed an UGI to check the durability of the repair and rule out a recurrence. The results suggested a significant benefit for the use of SIS mesh in the short-term, with the primary group having a 26% recurrence rate and the mesh group a 9% recurrence rate. While these results are encouraging, it is important to know what is the durability and the longer term benefits of the use of SIS mesh. For this reason we propose a follow-up of the original study patients with the same outcome measures (symptom questionnaire, SF-36, and UGI). This should give us a very good idea about the long-term success of laparoscopic PEH repair with primary and SIS mesh.

Biologic Versus Synthetic Mesh for Treatment of Paraesophageal Hernia

Hiatal Hernia

The investigators propose a randomized, single blinded controlled trial to compare the use of synthetic versus biologic mesh in hiatal hernia repair, two currently accepted standard of care surgical modalities. The investigators hypothesize that use of synthetic mesh will have lower recurrence at these time points compared to use of biologic mesh.
