Active clinical trials for "Hernia, Inguinal"

The study attempts to quantify the relative risks for chronic postoperative inguinal pain (CPIP) after Lichtenstein repair of groin hernia, depending on mesh type and fixation suture material. For this purpose the investigators will analyze data from the Swedish Hernia Registry (SHR).

This study assessed the outcomes of laparoscopic repair in complicated groin hernia. Laparoscopic approach in cases of complicated groin hernia can achieve desirable patient outcomes without major complications, provided good patient selection and expertise. This study provides an insight to the outcomes from the procedure in low resource setting of Nepal.

Previous studies have reported that about 3 % of patients who have had open inguinal herniorrhaphy had a visceral, ejaculatory-related pain. The investigators want to assess this problem among patients after laparoscopic inguinal hernia repair with(self-administered questionnaire study).

laparoscopic hernia sac high-ligation has a high recurrence rate laparoscopic hernia sac high-ligation and the lateral umbilicus ligament covering the hernia opening The investigators developed a method of laparoscopic hernia repair by applying a new concept in hernia repair. The hernia opening was tightened, and hernia opening region repaired with a lateral umbilicus ligament in a tension-free manner. This method combines the advantages of a secure repair achieved by the open method with the minimal invasiveness of the laparoscopic method. The investigators hypothesized that the lateral umbilicus ligament covering the internal hernia opening region after the laparoscopic purse-string knot would result in lower recurrence and the same operation relative complication.

Laparoscopic inguinal hernia repair is becoming increasingly popular mainly because of short-term advantages compared to open hernioplasties with mesh. In the prevailing economic climate, the total costs of treatment is a subject of intense research. This study is designed to evaluate the results of open and laparoscopic inguinal hernia repairs, with a special emphasis in costs of treatment, complications and convalescence.

The treatment of postoperative pain continues to be inadequate in the investigators practice setting. Inadequate pain treatment not only contributes to postoperative complications in the short term but can also be a factor that favors the development of chronic postoperative pain and diminishes long-term quality of life. Risk factors that can lead to a transition to chronic pain need to be analyzed.

Inguinal hernia repair may be done by the nylon darn, polypropylene mesh and other methods. Polypropylene mesh is established in the literature as the standard of care for inguinal hernia repair. It is however expensive and not readily available in our community hospitals. Nylon darn repair is widely used in our hospitals. We think that the quality of life following nylon darn repair and polypropylene mesh repair is similar. In order to find out, we are recruiting 79 patients to undergo nylon darn repair for their inguinal hernia and another 79 patients to undergo polypropylene mesh repair for their inguinal hernia repair. We are doing research to compare the quality of life after nylon darn repair of inguinal hernia to polypropylene mesh repair in patients aged 18 years to 80 years who come to St. Luke Hospital for their first-ever inguinal hernia repair.

Recent studies have focused on the role of endogenous opioids on central sensitization. Central sensitization is known to be impaired or altered in chronic pain conditions, as fibromyalgia or chronic tension headache. Animal studies have shown reinstatement of mechanical hypersensitivity following naloxone administration after resolution of an injury. This suggests latent sensitization. In the present study, investigators hypothesize that a high-dose target-controlled naloxone infusion (total dose: 3.25 mg/kg) can reinstate pain and hyperalgesia 6-8 weeks after a unilateral primary open groin hernia repair procedure. Investigators aim to show that latent sensitization is present in humans and is modulated by endogenous opioids.

The notable development and diffusion of prosthetic surgery of the abdominal wall over the last few years has led to the introduction of light weight meshes. The efficacy of inguinal hernia repair with light weight prosthesis, as well as the better or worse biotolerability with respect to those of light weight, remains questionable in literature, where a clear answer still remains to be given. If there exists a connection between the quantity of material implanted, the immunological reaction to the mesh, the induced oxidative stress and the degree of cicatrization, and consequently the long-term result of the efficacy of the operation, remains to be demonstrated. There are few studies on the immunological reaction to polypropylene meshes, and none on the oxidative stress induced by the mesh. Moreover, only one study has been published that clearly correlates the immunological reaction to the amount of prosthetic material, but was carried out on only a few patients. The aim of this research is to show if there is a relationship between the amount of prosthetic material used and immunological reactions as well as postoperative oxidative stress, and thus to evaluate, if present, the differences in the biological reaction and biotolerability between light-weight and heavy-weight meshes on a statistically significant number of patients.
