Filter by:The aim of this study is to compare 3D-laparoscopy versus 2D-laparoscopy with the use of HD resolution in cholecystectomy in terms of error rating, performance time and subjective assessment.
Endoscopic retrograde cholangiopancreatography and endoscopic ultrasound are increasingly being used to manage complex disease of the bile duct, pancreas and cancer. Gastroenterology patients at the Los Angeles County Hospital presents a unique and diverse patient population. Our aim is to study the biochemical, radiographic, and clinical predictors of bile duct stones. Exploratory aims include the study of the management of cholangitis, bile leaks, GI cancer diagnosis and management, and the management of pancreaticobiliary problems in the underserved. All patients managed by EUS or ERCP at the LA County & USC University Hospitals will be enrolled in the databaseThe timing, clinical presentation, and objective details of patient presentation are recorded prospectively. Additionally the results of the subsequent ERCP and EUS procedures. Subsequent, clinical course and pathology will also be recorded.
The purpose of this study is to determine the Levita Magnetic Grasper Device Safety and Performance in Laparoscopy.
This study is being done because the investigators wish to study ways to improve recovery after surgery. Injury, including surgical injury, causes inflammation. Inflammation is the body's attempt to protect itself and to start the healing process. Some surgical complications are related to the body's natural inflammatory response. Although mainly a healing response, inflammation can also have side effects which delay recovery. The investigators wish to determine the effect of a medication known as ibuprofen on recovery. You may know ibuprofen by the name Advil or Motrin. The medication will be given through the vein prior to the start of the surgery. Three blood samples will be taken, two while the patient is under anesthesia. The subject will be asked to complete several questionnaires.
Prospective, randomized , multicenter study comparing cholecystectomy performed with da Vinci Single Site Instruments™ to multi-port (four ports) laparoscopy
During laparoscopic surgery, your surgeon operates through 'keyhole' incisions in your abdomen. These allow long tools and a camera to pass to perform the surgery and allow the surgeon to see inside you. The cameras images are seen on a television screen, and this is viewed, like you watch television at home, in a two-dimensional (2D), form. This can make performing laparoscopic surgery very challenging, as you have to learn to appreciate depth while performing surgical tasks. Recent advances in viewing technology mean we now have the capability for comfortable three-dimensional (3D) viewing of laparoscopic surgery, and many centers have shown its superiority over 2D in lab-based experiments. However, this technology has never been compared against our normal gold standard 2D imaging in laparoscopic operations. This study aims to investigate whether there is a quantifiable benefit in using these new 3D imaging systems over 2D for laparoscopy, as we hypothesise that there is a marked benefit using 3D over 2D. Patients who have been placed on the waiting list for keyhole surgery to remove their gallbladder will be invited to take part in the study. If they agree, they will undergo the standard operation for removing their gallbladder as planned already. At the beginning of the operation they will be randomised (selected by chance) into one of two groups. One group will have their surgery performed to our current 'Gold standard' with the surgeon using a 2D camera and screen. The other group will have the exact same operation but with the surgeon using a 3D camera and screen. The intra-abdominal part of the operation will be recorded and viewed by an independent observer who is a surgeon, to assess for technical performance differences between operations performed in 2D and 3D, as well as time taken for the surgery. There are no extra risks to taking part and being randomised to the 3D group. The laparoscopic camera is the same size as a 2D camera and used in the same way. There are no real disadvantages, as patients will still undergo the operation they were booked for and will experience no change in their treatment. The aim is to compare 2D and 3D Day Case Laparoscopic Cholecystectomies, to see if there is a marked difference with this new technology. Lab based studies imply that 3D imaging systems reduce surgical errors and operating time therefore could improve patient safety. This study may help improve laparoscopic surgery for future patients.
Laparoscopic techniques have allowed surgeons to perform complicated intrabdominal surgery with minimal trauma. Laparoscopic cholecystectomy has been recognized since 1987 as the gold standard procedure for gallbladder surgery. Single incision laparoscopic surgery (SILS) was developed with the aim of reducing the invasiveness of conventional laparoscopy. In this study we aimed to compare results of SILS cholecystectomy and three port conventional laparoscopic (TPCL) cholecystectomy prospectively
The purpose of this pilot study is to compare the use of deep or standard neuromuscular blockade (NMB) in combination with low or standard insufflation pressure in participants undergoing a surgical procedure, laparoscopic cholecystectomy. Insufflation refers to the injection of carbon dioxide into the abdomen during the laparoscopic surgery, to allow visualization of and access to the surgical field. The primary hypothesis of the study is that the use of sustained deep NMB improves the surgeon's overall satisfaction with surgical conditions as compared to standard NMB. The in-patient surgery is performed on Day 1 and the participant remains hospitalized for at least 48 hours following the surgery (or at least 24 hours following the surgery, if local practice does not allow 48 hours of hospitalization post surgery). On Day 8, a follow-up visit/contact including all participants occurs.
The purpose of this study is to compare efficacy and safety of combination of propofol and midazolam with meperidine versus midazolam and meperidine for ambulatory ERCP
Background: The importance of ischemic ECG changes including St segment elevation, ST segment depression or T wave inversion that indicate myocardial ischemia are well established and require appropriate investigation and treatment. However, there is an abundance of clinical situation, with apparently ischemic ECG change not indicate traditionally coronary artery related ischemia and therefore require prompt recognition and treatment of underlying condition, that may be serious and life-threatened. For example of such conditions are pericarditis, myocarditis, aortic dissection, electrolyte abnormalities, intracranial hemorrhage and hypothermia. Together with them, an ECG ST segment changes may appeared in abdominal serious illness such as pancreatitis and cholecystitis(17,18,19,20,23). Whereas in pancreatitis various vasoactive and toxic for myocardium substances released, the cause of ST segment changes in cholecystitis are discussed and includes tachycardia , vagal reflexes, changed in plasma rennin activity resulted by distension of the gallbladder. The certain proportion of the patients with ECG changes actually didn't have coronary artery disease(9,15) or other acute cardiac condition and therefore require treatment of the underlie illness only without spend the time for cardiac investigation or special treatment(1,3,4,7,8). Some kind of treatment may be even harmful for the patients with abdominal illness such as thrombolytic, anticoagulant, aggressive antiaggregant therapy or unnecessary cardiac catheterization. In the medical literature the investigators found some case reports and works about the ECG changes in acute biliary disease in patient with knowing cardiac disease and without it, but actually incidence of ECG changes that suggest but not represent an acute coronary illness isn't knowing. Therefore this is necessary to investigate actually incidence of ECG changes that mimic acute coronary syndrome in acute cholecystitis and acute biliary disease and determined clinical and laboratory characteristics that helps to differentiate this patients.
