Active clinical trials for "Hernia"

This will be a single blinded, registry based, non-inferiority, randomized control trial comparing transfacial sutures for mesh fixation to no mesh fixation in open retromuscular repairs. The primary outcome of interest is recurrence measured one year postoperatively as per standard of care at Cleveland Clinic Center for Abdominal Core Health. Hence, recurrence will be measured using either physical examination, CT scan, or the Ventral Hernia Recurrence Inventory (VHRI). Study population will include all adult patients (18 years or older) undergoing elective open ventral hernia repair of a clean (Wound class I) defect, where the midline fascia can be approximated and mesh will be placed in the retromuscular position. Only a midline approach to hernia repair and hernia widths equal to or less than 20cm measured intraoperatively will be included

The purpose of this study is to compare the use of ultrasound-guided bilateral rectus sheath blocks to local infiltration of anesthetic agent in the surgical wound in a pediatric population of patients undergoing umbilical hernia repair.

The purpose of the study is to evaluate a new laparoscopic technique for parastomal hernia repair using an intraperitoneally placed Proceed mesh, looking at postoperative complications, recurrence rate and postoperative pain and quality of life.

Open inguinal hernia repair is one of the most common surgical procedures. Despite the fact that different of anesthetic procedures are proposed as alternatives to spinal anesthesia, the combination of spinal anesthesia with open inguinal hernia repair is preferred from both surgeons and patients. One disadvantage of this combination is the high incidence of post-surgery urinary retention, especially in men above 50 years old. This complication is partially attribute to overstimulation of the a1 adrenergic receivers of the bladder and the prostate. Preoperative administration of elective a1 blockers could inhibit this effect without side effects, since this drugs don't have systemic effect.

To determine the efficacy on decreasing the rate of surgical wound complications in patients undergoing repair of large incisional hernias, after the prophylactic application of a single-use negative pressure therapy dressing (PICO), versus a conventional dressing.

Patient comfort and satisfaction of inguinal hernia repairs can be affected by the anesthesia technique chosen in addition to the surgical method. In our study, we aimed to compare the anesthesia method used in patients during laparoscopic total extraperitoneal hernia repair, which is a minimally invasive method.It was planned to evaluate the patients' quality of life, pain conditions, additional medical support needs for pain, length of hospital stay, duration of surgery, complications during and after surgery and recurrence rates.In addition, it was planned to compare the effects of the anesthesia method used on the lung capacity of the patients. The most important achievement of the study will be to show that laparoscopic hernia repair, which is frequently performed by intubation, can be performed safely with the Laryngeal mask.

Introduction: Morbid obesity, defined as a body mass index (BMI) of over 40 kg/m2, is globally an imminent health threat. Conservative therapies do often not yield the desired result. Bariatric surgery includes several interventions that are performed on patients with morbid obesity, like gastric bypass surgery. The number of bariatric surgeries annually is estimated to be around 500,000 worldwide; about half of these are gastric bypass surgeries. In the Netherlands, the most common performed bariatric intervention is the Roux-en-Y gastric bypass (RYGB). An important long-term complication of this surgery is internal herniation, a condition in which a part of the GI tract is herniated through an opening in the mesentery made during RYGB surgery. Incidence of internal herniation is 1-5%. Conventional abdominal CT examination is often not conclusive about the presence of internal herniation. When internal herniation is clinically highly suspected after abdominal CT examination (but not necessarily confirmed), the patient is subjected to diagnostic laparoscopic surgery. Unfortunately, a negative abdominal CT scan does not exclude internal herniation in all patients. This pleads for the development or exploitation of alternative techniques that might aid in the diagnosis of complications after RYGB surgery. Since the anatomy of GI tract is altered when internal herniation is present, visualizing the mesenteric vasculature may aid in the diagnosis of this complication after RYGB surgery. This study aims to confirm the feasibility and superiority of diagnosing internal herniation using CT examination of the mesenteric arteries over conventional CT examination. Objectives: The primary objective is to determine whether abdominal arterial CT angiography is a feasible technique for diagnosing internal herniation after RYGB surgery. Secondary, it is examined whether arterial angiography of the mesentery is superior over conventional CT examination with oral and IV contrast in the venous phase. Study design: This study will be a prospective pilot study, in which the outcomes of both the conventional CT examination and abdominal angiogram are compared to the outcome of diagnostic laparoscopy as gold standard. Study population: Patients will be included who underwent laparoscopic RYGB surgery at least half a year earlier and have persisting abdominal pain. They should be highly suspected for internal herniation by their doctor, based on several characteristics. Main study parameters/endpoints: Primary study endpoints are the assessments of the arterial abdominal angiogram and mesenteric arterial mapping in relation to the outcome of the diagnostic laparoscopic surgery in 12 subjects. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In this pilot study, study subjects will receive an additional effective radiation dose of about 10 mSv. On average, an acute dose of 10 mSv leads to an additional risk of cancer of about 1 in 1750 (~1 in 2000 for males, ~1 in 1500 for females) for a 50-year old subject, based on the linear no threshold model. However, when the mesenteric artery mapping proves to be feasible and superior, many unnecessary diagnostic laparoscopic surgeries will be prevented (along with their complications and risks).

Aim of this study is to measure the effectiveness of topical gentamicin to prevent post-operative infection in inguinal tension-free hernia repair operation.Secondary aim is, if it is effective as a prophylactic agent, to compare it's effect with intra venous single dose cefazolin sodium prophylaxis.

Single-arm study of Phasix Mesh in High Risk patients looking at SSI and recurrence rates.

The purpose of this study is to compare rates of hernia formation between colostomies created with no hernia preventing mesh versus colostomies created with a particular mesh.
