Filter by:Herniorrhaphy is the most frequent general surgical procedure. There are moderate pain complaints after herniorrhaphy. Besides causing discomfort to the patients, pain, can delay recovery and discharge and cause cognitive dysfunction and difficulty with returning to normal daily activity. A combination of analgesics with different effect sites can reduce the doses needed and analgesic related side effects which is called multimodal analgesia . Opioids, acetaminophen, nonsteroid anti-inflammatory drugs and cox-2 inhibitors, alfa-2 receptor agonists, steroids, gabapentin and pregabalin have been used for this purpose(4). Tizanidine is an alfa-2 receptor agonist, and is used for musculoskeletal pain conditions. Tizanidine reduced the local anesthetic requirement in spinal anesthesia. The aim of this study is to investigate the hypothesis that: Tizanidine can reduce the pain scores, analgesic consumption, analgesic related side effects and provide early return to normal daily activity compared to placebo after inguinal herniorrhaphy.
Chronic pain after Lichtenstein hernioplasty is a common problem with an incidence of 11%. Many factors influence the onset and persistence of pain. Mesh characteristics and fixation have been pointed as important etiologic factors. This study compares two types of fixation for the same mesh. The mesh used is a lightweight parietex mesh. In the control group this mesh will be fixed with non absorbable sutures. In the study group sutures will not be needed because of self gripping microhooks on the surface of the mesh. Methods: The HIPPO trial is a multicenter double blind randomized clinical trial. Patients will be randomly allocated to the sutured mesh or the self-gripping mesh. Hernia repair will be done according to Lichtenstein as described by Amid et all. Included will be all unilateral primary inguinal hernia in man patients aged 18 years or older not meeting the exclusion criteria. Patients will be followed for two years. The main endpoint is the amount of post-operative chronic pain evaluated by VAS scores. The existence of neuropathic pain will be evaluated by the Paindetect questionnaire (and a bedside variant of the QST). Secondary endpoints are recurrence rate, post-operative complications, costs, hospital stay, QOL, return to work and daily activities, genital and sexual problems. To demonstrate a difference in VAS score of 10 with α=0.05 and power 80% a sample size of 400 patients is calculated. Discussion: Hypothesized is that the self gripping non-sutured mesh (Parietex Progrip) will cause less post-operative and chronic pain without enhancing the recurrence rate.
The aim of this study is to evaluate whether preperitoneal mesh placement using a nitinol containing large pore polypropylene mesh (REBOUND HRD™) offers a satisfying patient recovery, quick reconvalescence and adequate tissue integration with acceptable mesh contraction in a multicenter (Belgian) prospective trial. Patients treated by open preperitoneal mesh repair for an unilateral inguinal hernia according the current surgical practice in the participating centers will be observed during one year post-surgery, after which they will have a CT scan of the surgical area in the groin to evaluate the mesh changes regarding shrinkage and migration.
