Filter by:The study is planed on ASA I-III, 18-80 years old 60 patients developing chronic renal failure and needing arteriovenous fistula surgery for dialysis program in Istanbul Medeniyet University Goztepe Research Hospital. Informed consent of the patients will be obtained before surgery.Patients with hemoglobinopathy, coagulopathy, wound or infection in the thenar eminence, wound and infection in the supraclavicular region on the side of the regional block, allergic to local anesthetic drugs and mental retardation will not be included in the study. Standart monitorization (ECG, peripheral oxygen saturation and non-invasive arterial pressure monitoring) will be made. Base and 5 minutes interval values will be recorded until the end of the surgery. The pads of the NIRS monitor will be placed on the thenar eminence of both hands and fixed with the help of a draipe and basal measurements will be taken and recorded. The patients will then be divided into two groups according to computer-generated table of random numbers. Group L patients will undergo surgical cleansing and sterile draping and infiltrate %5 bupivacaine 15ml. Group B the supraclavicular areas of the patients who will undergo surgical procedures will be sterile covered after appropriate sterilization. After the brachial plexus is visualized around the subclavian artery in the supraclavicular region with the help of Samsung ultrasound device, Bupivacaine 5% 20ml and Lidocaine 2% 10ml will be applied around the brachial plexus using a 50mm stimuplex needle. The effectiveness of the block will be evaluated by a single investigator after withdrawal of the needle, either by effective anesthesia with the block or every 10 minutes up to 30 minutes. The sensory block will be evaluated with a 3 point scale and the motor block will be evaluated routinely before and after the modified bromage scale (scored between 0 and 4). After withdrawal of the treated needle, we will contact the relevant nerve dermatome with cold application (cold SF) and ask the patient to classify the degree of cold feeling from 0 to 3. Block will be considered unsuccessful if surgical block cannot be provided after 30 minutes or if the patient experiences pain at any time during the operation. The duration of anesthesia occurring after local infiltration of Group L and the sensory and motor blockade after group B stimulation is taken will be recorded. In both groups, NIRS values will be recorded at 5 minute intervals until the end of the case after local anesthetic application. Investigator will call the patients for primer patency of fistula one month after operation.
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.
comparison between to groups of patients with simple anal fistula one group underwent sistulotomy the other underwent fistulotomy and marsupialization of the wound edges , the investigator tested the incidence of postoperative complications , time of wound healing , operative time
This study is aimed to evaluate difference of the 2 year recurrence free survival after pancreaticoduodenectomy for pancreatic cancer between artery-first approach and conventional procedure groups.
Bile duct injury following cholecystectomy is an iatrogenic catastrophe associated with significant peri operative morbidity and mortality(1, 2) reduced long term survival(3) and quality of life(4, 5) and high rates of subsequent litigation6. It should be regarded as preventable. The advent of laparoscopic cholecystectomy has resulted in a resurgence of interest in bile duct injury and its subsequent management. Population based studies(6.7) suggest a significant increase in the incidence of injury (0•1 to 0•5 per cent) following the implementation of the laparoscopic approach(8) Bile duct injury should be regarded as preventable, but over 70 per cent of surgeons regard it as unavoidable(9). Although most injuries occur within the surgeon's first 100 laparoscopic cholecystectomies, one third happen after the surgeon has performed more than 200; it is more than inexperience that leads to bile duct injury(10). It has been suggested that the commonest cause of common bile duct injury is misidentification of biliary anatomy (70-80 per cent of injuries)(11,12),a reduction in risk if surgeons perform routine intraoperative cholangiography Recognition of bile duct injury at the time of cholecystectomy allows an opportunity for the hepatobiliary surgeon to assess its severity and the presence of any vascular injury
The optimal method of surgical treatment of complex anorectal fistulas has not been found yet. The aim of this study is to compare two techniques in treatment of high anorectal fistulas. This study purpose to demonstrate that the fistulectomy with dissection from 1/3 to 2/3 of the height of the sphincter complex with primary suturing is technically simpler, equally effective and safe in comparison with muco-muscular endorectal advancement flap.
The main aim is to check the long term side effects of a repeat treatment of darvadstrocel and to see if that treatment improves symptoms of Crohn's disease and complex perianal fistula. Participants will attend 8 clinic visits and will receive 1 treatment of darvadstrocel at the third visit. A magnetic resonance imaging (MRI) will be performed several times during the study.
The purpose of this study is to assess the impact of treatment (medical and/or surgical) on Health-related Quality of Life (HRQoL) in participants with Crohn's Disease (CD) and Complex Perianal Fistula (CPF), by the Quality of Life in patients with Anal Fistula Questionnaire (QoLAF-Q), at 12 months after treatment initiation in routine clinical practice.
