Active clinical trials for "Hernia"

The purpose of this study is to compare the clinical outcome of medical treatment associated with lumbar traction and medical treatment alone in the treatment of lumbar disk herniation.

Post-operative restrictions following lumbar discectomy is a controversial topic. While the most widely accepted protocol restricts bending, lifting, and twisting for four to six weeks following discectomy, a number of studies support an early return to full activity without restriction. Since the goal of discectomy is to promptly provide pain relief and a return to a fully active lifestyle, perhaps post-operative restrictions are more hindering than beneficial. Hypothesis: Post-operative restrictions following lumbar discectomy do not influence reherniation rate. Specific Aim 1: To compare the reherniation rates between the 6-weeks of restriction and the 2-weeks of restriction groups. Specific Aim 2: To determine the return to full activity and return to work dates of both the 6-weeks of restriction and 2-weeks of restriction groups. Specific Aim 3: To assess the health outcomes of both the 6-weeks of restriction and 2-weeks of restriction groups.

The aim of this study is to compare 3D-laparoscopy versus 2D-laparoscopy with the use of HD resolution in inguinal hernia repair in terms of error rating, performance time and subjective assessment.

The purpose of this study is to determine whether drainage after prosthetic repair of incisional abdominal hernias increases or decreases complications such as infection, seromas and hematomas.

This is an investigator-iniated pilot study to determine if MRI with diffusion tensor imaging (DTI) and tractography will yield useful information in patients suspected of having cervical spine disc herniation to provide imaging confirmation of whether or not disease is progressing and to assess response to treatment (regardless of treatment provided).

A prospective randomized study was performed including consecutive patients who underwent an elective laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis during the 18 months period. This prospective randomized trial aims to compare two umbilical closure techniques for trocar site hernia (TSH) in laparoscopic cholecystectomy.

Incarcerated inguinal hernia is one of the common acute abdomen abdominal surgery, often prone to intestinal necrosis and acute peritonitis.Using traditional tension hernia reparation, the recurrence rate were as high as 30%. In recent years, biological materials especially acellular matrix materials (Acellular Dermal Matrix, ADM) in resisting the infection, has become a research hotspot. In the project, the investigators try to address the role of ADM in incarcerated inguinal hernia patients.

This study aim to assess long-term results of an incisional hernia-prophylactic mesh placement during stoma reversal after total mesorectal excision (TME) for rectal cancer

Study is a prospective, multicenter, randomized trial evaluating whether prophylactic laparoscopic placement of a dual-component IPOM mesh around a colostomy may prevent parastomal hernia compared with conventional colostomy after abdominoperineal resection. Eligible subjects will be recruited prospectively from five Finnish Hospitals (Oulu University Hospital,Vaasa Central Hospital, Helsinki University Hospital, Lahti Central Hospital, Jyväskylä Central Hospital). Patients were considered eligible for this study if undergoing laparoscopic abdominoperineal resection for rectal adenocarcinoma. Patients are randomized to prophylactic preperitoneal placement of a dual-component mesh (Dynamesh IPOM) around permanent colostomy or to conventional permanent colostomy. Estimating a parastomal hernia rate of 50%, a sample size of 26 patients per each study group is projected to provide 90% power (1-beta) with a alpha 0.05 (2-beta) to detect a 40% reduction in risk for parastomal hernia at 1-year. Since we expect a dropout rate of 20%, 37 patients per study group will be included in this study. All abdominoperineal resections are performed using laparosopic technique. At the and of the abdominal laparoscopic phase the straight permanent end colostomy is performed. In the intervention group the 10 x 10 cm Dynamesh IPOM mesh is cut in the middle according to volume of the bowel. Stapled bowel end is then pulled through the crosswise opened mesh, which is pushed to the abdomen and fixed to the peritoneum. Follow-up visits are scheduled at 1-, 3- and 12-month after surgery. Patients are evaluated for their clinical status and C-reactive protein, leukocytes and hemoglobin are assessed at each control visit. Computed tomography (CT) scan with and without Valsalva maneuver is performed 12 months after surgery for radiological evaluation of possible parastomal hernia. The primary end-point of this study is the incidence of clinically and radiologically detected parastomal hernias, and their extent 12 months after surgery. The secondary outcome end-points were colostomy-related morbidity such as stomal stenosis, necrosis and/or wound infection.The extent of parastomal hernia was graded at CT according to the Hernia Society criteria. Statistical analysis is performed using a SPSS statistical software. Continuous variables are reported as the mean and standard deviation, whereas nominal variables are reported as counts and proportions. Univariate analysis is performed with the Mann-Whitney U test and Fisher's exact test. P-values < 0.05 are considered statistically significant.

Pain relief after open inguinal hernia repair could be improved by administration of TAP block or ilioinguinal/iliohypogastric nerve block. It is unclear which one works better. The investigators hypothesize that doing TAP block closer to the middle of the abdomen would result in improved pain relief due to simultaneous block of ilioinguinal/iliohypogastric nerves.
