Filter by:The aim of this study is to evaluate success, efficacy, feasibility and safety of a simple five step ultrasound guided local anesthetic infiltration technique for unilateral open inguinal hernia repair and to determine the non-inferiority of the block to spinal anesthesia by comparing intraoperative and postoperative complications, pain control and patient and surgeon satisfaction of the block with spinal anesthesia.
Background: Five billion people worldwide do not have access to safe, affordable surgical care. A significant proportion live in sub-Saharan Africa (SSA), where up to 50% of the population are children. There is limited literature on neonatal and paediatric surgery in SSA and children's surgery does not appear on any of the National Health Strategic Plans for the 47 independent countries across SSA. Objectives: To form a collaboration of surgeons and allied health professionals involved in children's surgery across SSA and collectively undertake the largest prospective cohort study of paediatric surgery in this region. Materials and Methods: Data will be collected via REDCap website on all patients with gastroschisis, anorectal malformation, appendicitis, inguinal hernia and intussusception, during a 1-month period of collaborators choice between October 2016 to April 2017, with a 30-day follow up until the end of May 2017. Estimated study population: 1450 patients from 50 institutions. Full ethical approval has been granted by the host centre; local ethical approval will be required at collaborating centres for participation. All collaborators will be co-authors. Primary outcome will be in-hospital all-cause mortality. Secondary outcomes will include post-intervention complications. Data will be collected on institutional facilities, patient demographics, duration from condition onset to presentation, peri-operative resuscitation, intervention and outcome. Differences in outcomes between SSA and benchmark data from high-income countries will be calculated using chi-squared analysis. Multi-level multivariate logistic regression analysis will be used to identify interventions and peri-operative factors associated with improved outcomes; p<0.05 will be deemed significant. Outcome: Results will be used to advocate for enhanced children's surgical services in SSA. We shall identify context-appropriate interventions associated with improved outcome. The collaboration will help to enhance research capacity in the region.
Danish male patients who had undergone bilateral TAPP (July 2012 to June 2013) were recruited from the Danish Hernia Database and cross-checked with hospital files and the National Patient Registry. A standardized postal questionnaire was sent out two years after the index surgery to investigate Patients Related Outcome Measures (PROMs) such as chronic post-operative pain.
The investigators prospectively studied ninety nine GERD patients following laparoscopic hiatal surgery combined with transoral incisionless fundoplication at two community hospitals. General surgeons and gastroenterologists participated in the study. GERD questions were recorded before and at six and twelve months.
This study is aimed to compare between the results of conventional lumbar discectomy and the newly used technique in our department; endoscopic lumbar discectomy in neurosurgery department Assiut university hospitals, so that we can offer our patients the best service in an updated and minimally invasive way.
Prospective non-randomized observational register study of all elective symptomatic incisional hernias operated on in the Hernia Center of Reference of Gross Sand Hospital using the novel endoscopic assisted Mini- or Less-Open Sublay technique. The data of all patients were prospectively documented in the German Hernia Registry "Herniamed". The novel MILOS-technique allows the minimal invasive implantation of large extraperitoneal meshes for the treatment of primary and secondary incisional hernias.
The use of computed tomography (CT) imaging is rapidly increasing in healthcare. Despite physicians' growing reliance on radiological assessments, however, the reliability and accuracy of reads are highly variable. Inconsistencies may result from multiple factors. The researchers hypothesize that the presence and quality of clinical information will affect radiologist's assessment of CT scans for the presence/absence of a ventral hernia.
Introduction: Morbid obesity, defined as a body mass index (BMI) of over 40 kg/m2, is globally an imminent health threat. Conservative therapies do often not yield the desired result. Bariatric surgery includes several interventions that are performed on patients with morbid obesity, like gastric bypass surgery. The number of bariatric surgeries annually is estimated to be around 500,000 worldwide; about half of these are gastric bypass surgeries. In the Netherlands, the most common performed bariatric intervention is the Roux-en-Y gastric bypass (RYGB). An important long-term complication of this surgery is internal herniation, a condition in which a part of the GI tract is herniated through an opening in the mesentery made during RYGB surgery. Incidence of internal herniation is 1-5%. Conventional abdominal CT examination is often not conclusive about the presence of internal herniation. When internal herniation is clinically highly suspected after abdominal CT examination (but not necessarily confirmed), the patient is subjected to diagnostic laparoscopic surgery. Unfortunately, a negative abdominal CT scan does not exclude internal herniation in all patients. This pleads for the development or exploitation of alternative techniques that might aid in the diagnosis of complications after RYGB surgery. Since the anatomy of GI tract is altered when internal herniation is present, visualizing the mesenteric vasculature may aid in the diagnosis of this complication after RYGB surgery. This study aims to confirm the feasibility and superiority of diagnosing internal herniation using CT examination of the mesenteric arteries over conventional CT examination. Objectives: The primary objective is to determine whether abdominal arterial CT angiography is a feasible technique for diagnosing internal herniation after RYGB surgery. Secondary, it is examined whether arterial angiography of the mesentery is superior over conventional CT examination with oral and IV contrast in the venous phase. Study design: This study will be a prospective pilot study, in which the outcomes of both the conventional CT examination and abdominal angiogram are compared to the outcome of diagnostic laparoscopy as gold standard. Study population: Patients will be included who underwent laparoscopic RYGB surgery at least half a year earlier and have persisting abdominal pain. They should be highly suspected for internal herniation by their doctor, based on several characteristics. Main study parameters/endpoints: Primary study endpoints are the assessments of the arterial abdominal angiogram and mesenteric arterial mapping in relation to the outcome of the diagnostic laparoscopic surgery in 12 subjects. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In this pilot study, study subjects will receive an additional effective radiation dose of about 10 mSv. On average, an acute dose of 10 mSv leads to an additional risk of cancer of about 1 in 1750 (~1 in 2000 for males, ~1 in 1500 for females) for a 50-year old subject, based on the linear no threshold model. However, when the mesenteric artery mapping proves to be feasible and superior, many unnecessary diagnostic laparoscopic surgeries will be prevented (along with their complications and risks).
Ventral hernias are common following abdominal surgery. Currently, there is no equipoise on when synthetic and biologic meshes should be used. Among open ventral hernia repairs, half are repaired using biologic mesh while half are repaired using synthetic mesh. The investigators hypothesize that biologic mesh as opposed to synthetic mesh repair of open ventral hernia repair is associated with decreased risk of major complications one year after surgery.
Incisional hernia is a common complication in visceral surgery and varies between 11 and 26% in the general surgical population. Patients requiring emergency laparotomy are at high risk for the development of incisional hernia and fascial dehiscence. Among this population the incidence of incisional hernia in patients undergoing emergency surgery varies between 33-54%. Incisional hernias are associated with a high morbidity rate, such as intestinal incarceration, chronic discomfort, pain, and reoperation and typically require implantation of a synthetic mesh in a later second operation. Fascial dehiscence represents an acute form of dehiscence and has been observed in up to 24.1% and is associated with a mortality rate up to 44%. The gold standard for abdominal wall closure during elective and emergency operations is a running slowly absorbable suture. In the elective situation it has been shown that prophylactic mesh implantation in high risk patients reduced the incidence of incisional hernia significantly. The investigators and others have shown that mesh implantation in patients undergoing emergency laparotomy or in contaminated abdominal cavities are safe . With a randomized controlled trial the investigators now aim to compare the incidence of incisional hernia after prophylactic mesh implantation versus standard of care in patients requiring emergency laparotomy.
