Active clinical trials for "Hernia, Inguinal"

Inguinal hernia repair is one of the most commonly performed surgeries around the world. It accounts for approximately 75% of all abdominal wall hernias and presents a lifetime risk of 27% in males and 3% in females. Since the modern concept of surgical hernia repair described by Bassini in 1887, with the technique that bears his name, several techniques have been developed in the last century in order to improve surgical outcomes after inguinal hernia repair. Different open repairs, such as anterior (Shouldice, McVay) or posterior (Stoppa) approach were described and developed, until Lichtenstein described the tension-free hernioplasty concept supported by the use of a prosthetic mesh to repair the hernia defect. Notable Improvements were observed with this technique in terms of recurrence, pain, and discomfort in comparison with previous tension repairs. Considerable advantages over open repair have been obtained with the introduction of minimally invasive surgery to inguinal hernia repair, in terms of patient comfort and recurrence rates. Regarding prosthetic material, meshes have evolved since the first Dacron mesh used by Lichtenstein. First generation meshes were manufactured using more material and for this reason they have been described as heavyweight meshes. New generation meshes have been designed with less material in order to diminish the inflammatory response and foreign body reaction, providing less chronic pain with similar recurrence rates than heavyweight meshes. The density (or weight) of the mesh, measured in g/m2, is inversely proportional to the size of the pore and lately it has been reported that one of the main aspects related to prosthetic materials is pore size. Large pore meshes use less material, consequently they have been associated with a better tissue ingrowth. The large pore of lightweight meshes is conditioned by the less amount of material used. All previous studies compare both light and heavyweight polypropylene meshes But in order to get a proper comparison of the behavior of meshes in the inguinal region it is important to include the material and the pore size. The aim of our study is to compare patient-reported outcomes with the use of either a Polytetrafluoroethylene (PTFE) large pore mesh (LP-PTFE) vs a small pore polypropylene mesh (SP-PPL).

The purpose of this study is to determine if self-fixating polyester mesh will have lower incidence of chronic postoperative pain and recurrence than non-fixating polyester mesh when used for laparoscopic inguinal hernia repair.

Aim of the study The aim of this study is to test the hypothesis that during laparoscopic hernia repair, disconnection of the hernial sac along with suture ligation of the neck is better than transperitoneal purse string suture around the hernial sac at the neck leaving the sac in continuity. Also to compare the two different laparoscopic techniques as regards operative time, recurrence rate, hydrocele formation, and other possible complications as bleeding, hematoma, injury of the vas and testicular atrophy and post-operative cosmetic results. ..

Repair of inguinal hernia is the most common operation of the general surgeon. In recent years, it was recognized that chronic postoperative pain is as important for postoperative outcome as recurrent hernia. The incidence of pain or discomfort ranges up to 60% of operated patients. Despite the fact that laparoscopic hernia repair has been shown to reduce postoperative pain compared to open hernia repair, up to 5% of patients suffer from persistent discomfort. During that operation the mesh is either fixed using a stapler or tissue adhesive glue. With the current study we compare postoperative pain between patients undergoing laparoscopic inguinal hernia repair with either mesh fixation using a stapler or tissue adhesive. The use of von Frey monofilaments allows to describe pain with a high sensitivity.

The study aims at detecting possible differences between an open (Lichtenstein) and a video-assisted (TEP) technique in treating recurrent inguinal hernia. The differences monitored are further recurrence and chronic pain as well as primary complications.

The purpose of this study is to test whether pregabalin added to the standard of care with dosing starting preoperatively and continuing for 1 week post surgery will decrease the intensity of acute post-operative pain following inguinal hernia repair.

The aim of the study was to evaluate the feasibility of day surgery for elderly patients undergoing elective open inguinal hernia repair. Medically stable patients aged 65 years or older, with postoperative care available at home, were randomized to receive treatment either as day-cases or inpatients. Younger day-case patients undergoing the same procedure served as controls. Outcome measures during two postoperative weeks were complications, unplanned admissions and visits to the hospital, unplanned visits to primary health care and patients' acceptance of the type of provided care. The investigators expected to find a higher degree of satisfaction in the patient group receiving day-case care.

This study compares the outcome of the four most commonly used operations for the repair of primary groin hernia including the new key hole surgical techniques. It aims at answering the question of whether the new technology really improve the outcome, saves time and reduce patient suffering.

The aim of this double-blind clinical trial is to examine outcomes and pain control after surgery in patients who underwent laparoscopic inguinal hernia repair (IHR) with the use of perioperative transabdominal plane (TAP) block. Research Question: Does transabdominal plane block improve pain when undergoing inguinal hernia repair? The endpoints include whether preoperative TAP blocks improve pain score (primary end point) and decrease opioid use (secondary endpoint) after an inguinal hernia repair. Other end points- complications after surgery.

Background: Mesh fixation is a critical step in laparoscopic Transabdominal Preperitoneal (TAPP) hernia repair because fixation is a significant step to prevent the hazard of mesh migration, but is supposed to be associated with a higher risk of acute and chronic pain compared with non-fixation. Fixation is more expensive than non-fixation. Objective: To compare the efficiency of mesh fixation in laparoscopic TAPP surgical repair of inguinal hernia using sutured repair versus tacker use. Patients and Methods: This prospective randomized comparative study was carried out on 60 patients who presented with a unilateral inguinal hernia and were assigned to laparoscopic TAPP hernia repair. Patients were randomly allocated into two equal groups (30 patients each); in group A, the mesh was fixed with a Titanium tacker, and in group B, the mesh was sutured and fixed with polypropylene 0.
