Filter by:Surgery is required for the treatment of many pancreatic conditions, either malignant or benign. Mortality of pancreatic surgery can be up to 3% even in expert centers. Morbidity is high, postoperative pancreatic fistula (POPF) being the main postoperative complication. In its current definition (drain output of any measurable fluid >= postoperative day 3 with amylase content >3 times the serum amylase activity and with clinical consequence), the incidence of postoperative PF is between 15 and 30 %. Most POPF resolve spontaneously but when refractory POPF occurs, it may lead to severe complications. POPF severity is graded as follows: grade B in case of change in medical management: infection without organ failure, specific medication (total parenteral nutrition, somatostatin analogs, antibiotics), persistent drainage > 3 weeks, angiographic procedure for bleeding, prolonged hospital stay; grade C in case of reoperation or PF-related organ failure or death. No specific prophylactic treatment of POPF is currently recommended by clinical guidelines. In clinical research, many prophylactic strategies have been attempted with partial efficacy. Endoscopic pancreatic sphincterotomy with plastic stent placement is effective in pre-and postoperative management of pancreatic fistula but with the need of a highly competent interventional endoscopist. Intrapapillary botulinum toxin injection is believed to induce relaxation of the pancreatic sphincter, leading to a " pharmacological " pancreatic sphincterotomy without any morbidity. A recent phase I/II prospective study has shown promising results in this indication, with no clinically relevant pancreatic fistula when botulinum toxin was injected. Based on this observation we hypothesize that intrapapillary botulinum toxin injection during an endoscopic procedure before surgery could be effective for the prevention of post-surgical pancreatic fistula
In last few years, there is a new technology that permits the endovascular fistula creation with a minimum vascular trauma and the first results show encouraging results with high technical success rate, low resurgent and failure rates and good usability for hemodialysis. The implementation of the endoFAVI realization in dialysis patients is an emergent procedure that in our hospital can contribute important benefits to the patients, savings to the health system, as well research and innovation in the implicate services.
The purpose of this study is to determine if endothelial cells derived from human umbilical vein are safe for use in conjunction with fistulotomy for the treatment of simple anal fistulas. Endothelial cells are a special kind of cell in the body that line the inside surface of blood vessels. The goal of the study is to evaluate the preliminary safety of human umbilical vein cells in anal fistula healing.
The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer
In treatment of perianal fistula several methods are described. However, since the Hippocrates basics of surgical treatment has not changed very much. the aim of this study is to evaluate the effectiveness of PRP gel in treatment of perianal fistula.
How does oesophageal atresia/trache-oesophageal fistula affect feeding and swallowing in the first year of life? Approximately 150 babies a year are born with oesophageal atresia and/or trache-oesophageal atresia. Oesophageal atresia occurs when the oesophagus (food pipe) fails to join up during early foetal development. Trache-oesophageal fistula describes an abnormal connection that forms between the oesophagus and trachea (wind pipe). When the baby feeds, milk cannot pass into the stomach but can pass into the lungs. Surgery is needed within the first few days of life and is extremely successful, with 90-95% of babies surviving. However, approximately 50-80% of babies will have ongoing feeding or swallowing difficulties resulting in choking, chest infections and pneumonia. They can also lead to food refusal, distress at mealtimes and parental anxiety. Currently there is limited understanding of: - the exact nature of the feeding and swallowing difficulties - the risk factors for developing difficulties - the impact on parents. This study will address these issues through two complimentary projects: Project 1: A study of swallow physiology Babies with oesophageal atresia and/or trache-oesophageal fistula who have surgery at Great Ormond Street Hospital will be invited to have a detailed swallow assessment using videofluoroscopy (video x-ray) and high resolution impedance manometry (a pressure monitor) at 2-4 months of age and at 8-12 months of age. Results will be compared to parent report of feeding at 1 year old. Project 2: A study of the impact on parental well-being This study will be carried out in conjunction with the 'TOFS' support group. A Facebook page will be used to carry out an online forum. Parents of any child who has had TOF/OA will be invited to share their experiences of establishing feeding. This information will be used to develop a questionnaire to look at how wide-ranging these experiences are.
Anal Fistula can be a challenging condition to treat. Microdialysis has never before been used to examine the inner environment of anal fistula. This is now going to be performed.
Robot-assisted Vesico-Vaginal fistula (VVF) repair was described a few years ago as an alternative to the open approach to minimize the morbidity of this surgery. Very little series have reported the results of robotic VVF repair. The objective of this work was to evaluate the results of robotic VVF repair.
Many guidelines at home and abroad advocate that arteriovenous fistula should be the first choice of permanent vascular access, but it is easy to form thrombus in a short time after arteriovenous fistula molding, resulting in internal fistula stenosis or occlusion. In this study, the investigators plan to screen the patients with arteriovenous fistula in the blood purification center of our hospital. Through the study design of random grouping and open label, the investigators will discuss the use of low molecular weight heparin or warfarin to prevent thrombosis in a short period of time after arteriovenous fistula operation. According to the research results, the investigators will understand efficacy and safety of short-term postoperative anticoagulant therapy to prevente thrombosis in arterovenous fistula.
Laser closure of the perianal fistula is the minimally invasive and low complication rate procedure which is a life-saving way for complex fistulas, preserving anal sphincter injury. Unfortunately, wide range success rate reported before (30-80%), the investigators are searching to reach better rates. Internal closure of the fistula orifice offered by some authors. The investigators are aimed to identify the efficiency of this.
