Active clinical trials for "Hernia, Inguinal"

The effect of intraoperative infiltration of the operation site with bupivacain on the development of chronic pain is the object of our trial. We hypothesize that the occurrence of chronic pain in the goup of patients receiving the infiltration will be 50% less than in the placebo group receiving normal saline. The study is a randomized controlled triple blinded trial with a sequential study design.

Background: The aim of this study was to investigate the efficacy of prone-position computed tomography (CT) for detecting and classifying inguinal hernia relative to supine-position CT before laparoscopic inguinal hernia repair. Materials and Methods: Sixty-eight patients who underwent laparoscopic transabdominal preperitoneal repair of inguinal hernia were enrolled in this prospective study. Patients diagnosed with inguinal hernia by physical examination underwent abdominal CT in the supine and prone positions for preoperative assessment. The anatomy of the right and left inguinal regions was confirmed during the surgery and compared with the preoperative CT findings.

Significant concern regarding the safety of general anesthesia in children has arisen due to myriad animal studies suggesting neurotoxicity of commonly used anesthetic agents. Inflammation of the central nervous system after anesthesia may have a significant role in the pathogenesis of anesthetic-induced neural injury. To evaluate this hypothesis, the investigators propose to randomize healthy infants undergoing elective surgery to one of two anesthetics: 1) spinal anesthesia only; or 2) general inhalational anesthesia with isoflurane, laryngeal mask airway (LMA) or endotracheal tube (ETT), and single-shot caudal block. Primary endpoint will be serum inflammatory biomarkers and transcriptome analysis and secondary endpoint will be neurocognitive outcome at 6 months and 1 year.

Does corticosteroid (dexamethasone) have an effect on the postoperative period after laparoscopic hernia repair, when it comes to pain, postoperative nausea and vomiting and convalescence. This randomized, double-blinded study compares dexamethasone versus placebo. The patients are recommended one day of convalescence. The medicine or placebo is given before operation. The patients fill out questionnaire before operation and three hours after operation and in the following three days. The patients also register when they return to normal activities and work.

Inguinal hernia repairs is clean surgical procedures. However infection may be a concern when prosthetic materials are used. This prospective randomized study has been set to observe if antibiotic prohylaxis is of benefit in mesh repair of inguinal hernias.

Chronic inguinal neuralgia is one of the most important complications following inguinal hernia repair. It may even outweigh the benefit of the operation. Intraoperative neurectomy has been investigated to reduce the incidence of chronic pain. This study evaluates the effects of elective division of the ilioinguinal, iliohypogastric and genital branch of the genitofemoral nerves on pain and postoperative sensory symptoms after Lichtenstein hernia repair.

Inguinal hernia have traditionally been done under general anesthesia. While safe, general anesthesia is associated with potential postoperative nausea/vomiting and drowsiness. Additionally, the recent COVID19 pandemic has heightened the precaution to avoid aerosol generating procedures (AGP) if possible. General anesthesia requires airway manipulation, thus necessitate performing an AGP. Recently, we began using peripheral nerve block and sedation as primary anesthetic technique for inguinal hernia repairs. While surgeon administered local anesthetic, also known as local infiltration, has been done for inguinal hernia repair, using specific nerve blocks and sedation has not been compared with general anesthesia. We believe the advantage of this novel technique can improve postoperative recovery. This retrospective study will compare the total hospital length of stay of those receiving nerve blocks and sedation as primary anesthetic techniques versus those with general anesthesia.

Randomized trial to compare outcomes of laparoscopic and robot assisted inguinal hernia repair.

The purpose of this study is to determine whether laparoscopic inguinal hernia repair leads to a lower incidence of chronic pain compared to open herniorrhaphy.

Laparoscopic contralateral patent processus vaginalis (CPPV) repair in infancy and childhood is still debatable, due to the high CPPV rate but low contralateral metachronous hernia (MCIH) rate. In order to found risk factors for MH, we conducted this prospective study. This is an multi-center investigator-initiated observational prospective trial. After informed all the benefits and risks of repair CPPV simultaneously, those patients with unilateral inguinal hernia whose parents preferred not to repair CPPV simultaneously will be assigned in the study. All information about demographic data, hernia side, CPPV type and CPPV diameter will be recorded. The subjects will be followed up until MCIH developing or to 24 months postoperatively. Patients will be analyzed to identify the risk factors for MH.
