Active clinical trials for "Hernia"

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).

Introduction: parastomal hernia (PH) is a frequent complication after an ostomy, despite the many prevention and treatment techniques that have been described. Since the introduction of laparoscopy, the frequency of PH is even higher than in open surgery. This type of hernia remains a surgical problem of considerable importance, requiring significant consumption of public health and economic resources, and representing a major alteration of the quality of life of these patients. Objective: to evaluate the effectiveness of the insertion of a prosthesis to prevent PH in elective surgery for laparoscopic abdominoperineal resection. Methodology: prospective, multidisciplinary, multi-center randomized controlled study. Control group: Rectal neoplasms undergoing elective surgery for laparoscopic abdominoperineal resection. Study group: Rectal neoplasms undergoing elective surgery for laparoscopic abdominoperineal resection with a lightweight mesh (polypropylene and poliglecaprone 25). Sample size was calculated based on a proportion of parastomal hernia of 65% in the control group and 15% in the study group. With an α risk =0.05 and 1- β= 0.8, 28 patients are required, 14 per group. Estimating a drop-out rate of 10%, the final number will be 32 patients. The efficacy will be evaluated clinically at six months and abdominal CT will be performed at 12 months along with another clinical evaluation.

Postoperative seroma formation is one of the most common complications after ventral hernia repair. Although some seromas may not have clinical impact, postoperative seroma formation often causes pain and discomfort and may even compromise wound healing. The use of postoperative abdominal binder is often recommended after ventral hernia repair to prevent seroma and diminish pain, but still with no scientific evidence. The primary aim of the present study is to investigate the effect of postoperative abdominal binders after laparoscopic ventral hernia repair on postoperative pain, discomfort and quality of life. Secondary, we register seroma formation. Method and material Randomized, controlled, multi-center, investigator-blinded study. A minimum of 56 patients (2X28 umbi/epi) are included, inclusion number is based on power calculations. Patients are randomized either to abdominal binder or no abdominal binder. The abdominal binder is worn from immediately after the operation and continuously for 7 days, night and day. Outcomes are based on patient self-reported registrations using Visual Analog Scales (VAS) and Carolina Comfort Scale (CCS), which is a validated, hernia-specific tool to estimate quality of life, pain and discomfort. Patients are followed-up for 30 days. For secondary outcome we use ultrasound to measure the volume of seroma formation. We use Mann-Witney, non-parametric statistics calculating the seroma formation and Friedmanns test for pain, discomfort and quality of life for the effect of time on inter- and intragroup differences during the study period. P < 0.05 is considered significant.

The investigators will perform a randomized controlled trial with a stratified-block design to compare the effect of the part versus whole task simulation training for TEP repairs.

The purpose of this study is to determine the efficacy of mesh fixation using absorbable versus non-absorbable sutures.

The purpose of this study is to determine whether a technique using very small stitches when closing a midline incision can reduce the risk for wound complications such as incisional hernia, infection or dehiscence.

The primary objective of this study is to compare with PFDI-20 questionnaire the functional outcome of laparoscopic sacrocolpopexy and vaginal mesh surgery in the treatment of symptomatic exteriorised cystocele up to 4 years after surgery. The secondary objectives of this study are the following: to compare the two techniques for anatomical results based on the clinical evaluation of patients with POP-Q. to overall quality of life assessment and expectations of patients. to compare the two techniques for the long-term safety. The evaluation will focus on the adverse effects of long-term sexual and genital symptoms, urinary and digestive functional symptoms, and chronic pelvic pain. to compare the improvement of the functional outcome assessed by PFDI-20 questionnaire (matched-analysis before versus after).

The purpose of our study to quantitatively examine the stress levels prior to surgery and the use of analgesics post surgery in both children and their parents following a preoperative intervention with a medical clown compared to children that were not exposed to this intervention.

The purpose of this study is to compare the neoClose abdominal closure to the standard Carter-Thomason closure in a bariatric surgery gastric bypass population.

This study aims to evaluate the efficacy and safety of a novel port-site closure device (EZ Close) by comparing it with the Carter-Thomason device.
