Active clinical trials for "Hernia"

The effectiveness of laparoscopic inguinal hernia repair still remains unclear. During a one year period a total of 1208 inguinal hernias in 952 patients were consecutively operated using the laparoscopic technique by a total of 11 general surgeons in daily clinical routine. Laparoscopic hernia repair in the TAPP technique seems to have the potential to become the standard procedure in inguinal hernia repair in future.

Systemic lidocaine administration may improve postoperative pain and recovery after laparoscopic inguinal hernia repair in pediatric patients

There are in excess of 1 million operations performed annually to repair inguinal hernias, mostly in the male population. Unfortunately, some patients continue to suffer both groin or testicular pain for varying lengths of time postoperatively. This can lead to a severe degradation of the patient's lifestyle, work habits and sexual function. The origin of the pain is felt to be secondary to the inflammatory reaction caused by the mesh. This also involves the spermatic cord and its structures, leading to orchidinia and possibly azospermia.

The objective of this study is to examine the safety and efficacy of porcine acellular dermal matrix mesh (Strattice; LifeCell Corp., Branchburg, NJ) in crural reinforcement of laparoscopic large paraesophageal hernia repair.

The objective of this study is to assess the recurrence rate following the use of PARIETEX™ Composite Ventral Patch in primary ventral hernia repair by open approach with intra-peritoneal positioning.

The aim of this clinical trial is to investigate the safety and efficacy of prophylactic mesh on prevention of parastomal hernia(PSH) after ileal conduit urinary diversion (IC) in a randomized controlled fashion.

Introduction Parastomal hernia is the most common complication related to colostomies. The variability of the diagnostic criteria, the fallow up time and sometimes subclinical dimensions, detectable only with imaging, explain disparate figures cited in the literature (0-58%) (1). The generally accepted rate is around 50% (2). However, several authors consider that actually, almost all patients present parastomal hernia in the long-term fallow up (3). Prophylactic prosthetic meshes could reduce the incidence of this complication, reinforcing since the beginning the weak peristomal area of the abdominal wall. Existing scientific evidence, although positive, is limited and does not allow to clarify some controversial issues as the type of prosthetic mesh to be used and the optimal position of the mesh in relation to the abdominal wall (4-8). The use of laparoscopic approach in colorectal surgery is increasing and also sets technical changes to the placement of the mesh. To date, there are some technical notes (9) and two published prospective, observational studies that include patients underwent laparoscopic surgery. In the first study intraperitoneal (10) and in the second retromuscular mesh (11) is used, with encouraging short-term results, but they need more scientific support. Study Design This is a prospective, randomized, single center, clinical study where the sample is represented by patients undergoing elective laparoscopy assisted colorectal surgery, with the creation of a permanent end colostomy. Patients who accept to participate and are suitable for inclusion to the study will be randomized into one of the two branches consecutively: Treatment A: Conventional definitive end colostomy; Treatment B: Definitive end colostomy reinforced by retromuscular mesh Ultrapro. Aims Evaluate and compare the results obtained by placing prosthetic mesh to prevent parastomal hernia end colostomy versus realization of end colostomy by conventional technique. Primary Objective: Compare the incidence of parastomal hernias between groups during the monitoring period. Secondary objectives: Compare the overall and specific postoperative morbidity and mortality between groups, compare the difference in surgical time between the conventional technique and the prosthetic mesh group, compare hospital stay between the groups.

Design Prospective , randomized, parallel phase IV. Objectives Main objective Evaluate the effectiveness of the placement of a resorbable mesh in the prevention of incisional hernia of the abdominal wall at the site of a loop ileostomy when it is "closed " to rebuild the intestinal transit. The effectiveness evaluation is done by tracking with scheduled patient visits for 12 months, assessing the physical examination the presence or absence of an incisional hernia and an abdominal tomography at the end of the 12 months . Secondary objectives Comparison of complications(morbidity and mortality) to assess safety and tolerability of the placement of the mesh described .

The investigators perform a simple-blind randomized trial with two groups, one in which all the orifices are closed by suturing the external fascia of the abdominal wall (Group A), and another in which the orifices are left open, closing only the skin (Group B). Monitoring for trocar site hernia lasted 2 years from the intervention.

Primary aim: 1. To compare the nerve stimulation vs. anatomic techniques of paravertebral block of T11-L1 in providing surgical anesthesia for patients undergoing inguinal hernia repair. Secondary aims: Compare VAS pain scores in the two groups of patients over the first 24 hours. Compare opioid intake over the first 24 hours in the two groups of patients.
