Filter by:Background: Obesity and hiatal hernia are both risk factors of gastroesophageal reflux disease (GERD), and the incidence of hiatal hernia is much higher in morbidly obese patients. Many believe that higher intra-abdominal pressure with higher esophagogastric junction (EGJ) pressure gradient in morbidly obese patients is the main mechanism accounting for the occurrence of GERD. Hiatal hernia, on the other hand, is associated with structure abnormality of EGJ. Sleeve gastrectomy (SG) has been becoming a standalone bariatric surgery for decades, and it has been proved to effectively induce long-term weight loss in morbidly obese patients. Some studies found morbidly obese patients benefited from resolution of GERD after SG, however, other studies had the opposite findings. Some morbidly obese patients had aggravating GERD or de novo GERD after SG. The mechanism is still unclear now. It might result from removal of fundus and sling muscular fibers of EGJ, increased intra-gastric pressure (IIGP), and hiatal hernia after surgery. High resolution impedance manometry (HRIM) is used to access esophageal and EGJ function objectively. Impedance reflux was more frequently observed in patients having gastroesophageal reflux (GER) symptoms after SG. In addition, previous studies also found decreased EGJ resting pressure, decreased length of lower esophageal sphincter (LES), and presence of hiatal hernia were associated with more GERD after SG. Objective: To evaluate the long-term EGJ function and GERD in morbidly obese patients with hiatal hernia receiving laparoscopic sleeve gastrectomy (LSG) with or without hiatal hernia repair (HHR).
Single-incision laparoscopic cholecystectomy (SILC) requires a larger incision than standard laparoscopy, which may increase the incidence of incisional hernias. This study evaluated SILC and standard multiport cholecystectomy with respect to perioperative outcomes, hospital stay, cosmetic results, and postoperative complications, including the 5-years incisional hernia rate.
It is a randomized controlled trial in which we are comparing onlay mesh hernioplasty with sublay mesh hernioplasty for paraumbilical hernia.
It is a randomized controlled trial in which we are treating inguinal hernia patients with mesh hernioplasty and either neurectomy of iliohypogastric nerve and ilioinguinal neurectomy or preservation comparing post operative acute or chronic pain
The study attempts to quantify the relative risks for recurrence depending on complex combinations of plausible risk factors, in particular mesh, mesh fixation, hernia size and hernia type. For this purpose the investigators will analyze data from the Swedish Hernia Registry (SHR).
Lumbar disc herniation is the most common diagnosed degenerative pathology in the lumbar spine with a prevalence of 2 to 3% in the adult population. Unilateral lumbar disc herniation is characterized by compression or irritation of the lumbar nerve roots or dural sac by either protrusion, extrusion or sequestration of the nucleus pulposus, mostly in the posterolateral region. Compression or irritation of the lumbar nerve roots and dural sac can induce unilateral sensory and motor symptoms. Therefore, it is the principal cause of lumbar spinal surgery. Different imaging studies have investigated asymmetry of the paraspinal muscles in patient with unilateral low back pain due to lumbar discus herniation. Both animal and human studies indicate a reduction in total muscle cross-sectional area, increased fat infiltration and fibrosis within the lumbar multifidus at the affected side. Increased fat infiltration is clinically important because there is a correlation between the amount of intramuscular fat and lumbar muscle dysfunction. Not only fat infiltration correlates with lumbar dysfunction, also a lower multifidus cross-sectional area is associated with and predictive for low back pain. This indicates that there is an association between paraspinal muscle changes/ remodeling and muscle dysfunction that could lead to low back pain. The aim of this research is to quantify the decrease in muscle and muscle fibre size, the amount of fat infiltration, and the amount of fibrosis present within the multifidus muscle at the herniated side in relation to the unaffected side. The second aim is to investigate the possible role of different cell types in the process of muscle remodeling. The last aim of this study is to correlate these muscular changes with long-term functional outcomes such as pain, fear and disability. This information can possibly contribute to the etiology of paraspinal muscle changes, and provide a handgrip to future research.
IntraSPINE® is a novel device that, unlike interspinous positioned implants, is unique in being placed more anteriorly in an interlaminar position, closer to the normal center of rotation of the motion segment. Mechanical advantages are thus conferred over more posteriorly positioned devices through the possibility of more physiological 'rocking' type movements in flexion and extension . This enables IntraSPINE® to off-load the facet joints in extension without blocking movement. Having a more anteriorly placed fulcrum also helps control excessive flexion movements by virtue of an improved lever arm in conjunction with an intact posterior tension band. The underlying hypothesis of this work is that a clinical gain is achieved by adding an IntraSPINE® interlaminar device to discectomy in patients suffering from a lumbar disc herniation. This should result in an improvement in incapacity level and a reduction in pain.
Rationale: Approximately 7000 stomata are created in the Netherlands every year. The occurrence of a parastomal herniation is high, with a reported incidence of 4-48%. Also, the former stoma site is at increased risk for the development of an incisional hernia. A clinical incisional hernia rate of 30% is reported after stoma reversal. Herniation can cause pain, deformity and possibly incarceration, which results in a significant impact on the quality of life of the patient. The hypothesis of this study is that the use of a prophylactic mesh at the time of stoma formation leads to a lower incidence of incisional hernias after stoma reversal, an improved quality of life and therefore a possible cost reduction in healthcare. Objective: To evaluate the incidence of incisional hernias after stoma reversal after preventive mesh placement compared to no mesh placement. In addition, we aim to assess the effect of preventive mesh placement on the quality of life and the effect on healthcare cost reduction by avoiding re-intervention. Study design: A multicentre double blind randomized controlled trial with a total follow up of 24 months. Study population: Adults (18-99) undergoing bowel resection with the formation of a temporary stoma. Intervention: A preventive mesh will be placed using a sublay keyhole technique (pre-peritoneal, retromuscular) at stoma formation. The mesh will be left in situ after stoma reversal and the hole in the mesh will be closed, to prevent incisional herniation. Main study parameters/endpoints: - Primary: Incidence of incisional hernias after stoma reversal - Secondary: Quality of life, stoma related prolapse or parastomal herniation, cost effectiveness and mesh related complications. Nature and extent of the burden and the risks associated with participation, benefit and group relatedness: The standard surgical procedure for the treatment of parastomal hernias is used in a prophylactic fashion. As this is standard care in parastomal hernias the risks are minimal. The mesh that is used is CE approved. The burden of participation in this study is minimal for the patient all follow-up visits coincide with the regular visits for colorectal cancer. Hence, no extra outpatient department visits, and even no additional diagnostics nor other medical procedures that could potentially burden the patient, are required.
Observational study on the effectiveness and safety of integrative Korean medicine treatment for inpatients with sciatica due to lumbar intervertebral disc herniation
We wish to use the images a mother would have done as part of her normal medical care and make both 3D animations and 3D models of the baby and it's CDH. This will both help the parents see what the problem is and also allow the surgeons, who will operate on the baby once it has been born, to see the size of the hole and what organs are in the wrong place.
