Active clinical trials for "Hernia, Hiatal"

This is an investigator initiated pilot study to observe the short-term outcomes (a follow-up period of up to six months) of patients who undergo a laparoscopic paraesophageal Hiatal hernia (PEH) repair using the Veritas® Collagen Matrix brand biological mesh. This is a preliminary study at the University of Washington. A PEH occurs when the stomach protrudes through the diaphragm next to the esophagus. The chance of recurrence of a Hiatal hernia after laparoscopic PEH repair is between 20-40% within 6 months.During laparoscopic PEH repair, a mesh-type product is used as a scaffold. The mesh serves as a reinforcing material during the surgical repair. It is cut to the appropriate size needed for the hernia and sutured to the surrounding diaphragmatic tissue. There are many different types of meshes available on the market, and vary in the degree of manageability, strength, and adherence. Although surgical meshes work on the same principal, the variance between materials may affect patient outcomes. There is evidence that a biologic mesh, specifically one derived from Small Intestinal Submucosa (SIS), decreases the short-term (6-month) recurrence rates compared to a synthetic mesh or another type of biologic mesh. A biologic mesh, serving as a scaffold, will be replaced by the patient's own tissue after about 6 months. Theoretically, this would prevent the possible complications associated with synthetic mesh including mesh erosion into the esophagus or stricture of the esophagus. There are some case series showing similar short-term results between the different biologic meshes, but there is no direct comparative data.

Miromatrix Medical has developed MIROMESH® - a new, noncrosslinked, acellular mesh derived from the highly vascularized porcine liver. MIROMESH received FDA 510(k) clearance with an indication for reinforcement of soft tissue on March 31, 2014 under K134033. This study will serve to provide clinicians with high-quality clinical data in order to provide them with a higher degree of confidence when selecting MIROMESH for hiatal hernia repair.

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.

Groups of patients who underwent laparoscopic repair of large hiatal hernias by primary posterior crural repair and crural repair with ProGrip™ mesh techniques were examined for recurrence rate of hiatal hernias, quality of life according to the GERD-HRQL questionnaire. Clinical evaluation was performed at 3, 6, 12, 24, 36, and 48 months after surgery.

One-hundred and fifty-nine patients undergoing Nissen fundoplication for symptomatic gastro-oesophageal reflux disease (GORD), who had a concomitant hiatal hernia of > 2 cm axial length, were randomized to closure of the diaphragmatic hiatus with either crural sutures alone or tension-free closure with a non-absorbable mesh. Primary outcome variable was the incidence of radiologically verified recurrent hiatal hernia. Secondary outcomes were per-and postoperative complications and courses, symptomatic recurrence rate, use of PPI, postoperative oesophageal acid exposure and Quality of Life.

The Mayo Clinic Foregut Surgery Report Card Questionnaire has been created in order to have a consistent evaluation tool for patients undergoing foregut surgery in order to standardize and validate outcome measures.

Laparoscopic Nissen Fundoplication has established itself as the procedure of choice in the surgical management of the majority of patients suffering from gastroesophageal reflux disease (GERD). Postoperative paraesophageal herniation has incidence ranges up to 7% in the immediate postoperative period. This randomized controlled study was scheduled to investigate the role of the posterior gastropexy, in combination with laparoscopic Nissen fundoplication, in prevention of paraesophageal herniation and improvement of postoperative results, in surgical treatment of GERD.

This study compares complete dissection of the tissue around the lower esophagus to no dissection of these tissues during laparoscopic fundoplication in children.

This monocenter randomized controlled trial aims to compare postoperative outcomes of a laparoscopic valvuloplasty with a Toupet fundoplication in patients with GERD with a maximum hiatal hernia of 3cm. In addition, an economic evaluation of the new intervention will be done in order to determine cost-effectiveness and costs per quality-adjusted life-year (QALY).

The present proposal aims to asses which is the optimal treatment strategy in a clinical study in patients with paraoesophageal hernia (PEH), a condition often found in elderly, fragile patients The investigator want to study the optimal approach to a paraoesophageal hernia (PEH) repair. The incidence of PEH increases with age and the older patient typically has additional co-morbidities, reduced physiological fitness, and frailty which makes surgery challenging regarding increased morbidity and mortality. Thus, the decision to offer surgery can be challenging in this cohort of patients. The need of an anti-reflux procedure as part of the repair is one of the main subjects for discussion worldwide. To date no consensus exists and many surgical centres do a routine anti-reflux procedure as part of their standard operation for PEH. But is this procedure redundant? Can the patients be managed with a less complicated procedure; an anterior gastropexy with comparable outcome?
