Filter by:We have designed a new method which could be used in laparoscopic cholecy- stectomy.Account to this new method, the three incisions are all located on the lower abdominal, theoretically it could get more beautiful outlook and less stress response than traditional laparoscopic cholecystectomy(two of the three incisions located on upper abdomen) or single port laparoscopic cholecystectomy(one large incision located on umbilicus). We plan to conduct a randomized controlled trial to compare those there methods of laparoscopic cholecystectomy, in order to find out if there will be some advantages of this new method,such as in lowering the stress response,reducing impact on respiration, relieving post-operation pain and improving appearance.
Cholecystectomy is one of the most common operation performed by general surgeons. Since, first video-laparoscopic cholecystectomy in 1987, laparoscopic cholecystectomy (LC) has become the gold standard treatment for benign biliary disease. In daily practice, LC has increased general surgeons familiarity to video-laparoscopic operations and has become the first step to search more minimally invasive techniques and to perform advanced laparoscopic operations. In order to move forward the minimal invasive surgery concept with less surgical trauma and better cosmetic results, surgeons firstly reduced the number of incision and ports, then the idea of totally eliminating skin incisions through the use of natural orifices was implemented in selected cases. In theory, minimal incision must provide minimal postoperative pain and better cosmetic results. With the use of single-incision laparoscopic cholecystectomy (SILC), this purpose is achieved by means of cosmesis but providing minimal postoperative pain is still controversial. Recent reports on, LC vs. SILC showed significantly favorable cosmetic benefit, comparable complication rate and hospital stay with SILC, but the mean operation time was significantly longer. Today, lack of standardized operation technique, the need for specialized instruments, the fear of inability to apply safe cholecystectomy principles, longer operation time, cost-effectivity and advanced laparoscopic experience are still limiting factor to performing SILC. The aim of this prospective randomized controlled trial is to compare gold standard LC and SILC using our new technique called "Pick'n roll" (SILC-PR). Our goal was to provide critical view of safety and safe cholecystectomy principles on SILC, improve operator ergonomics and shorten operation time while eliminating the need for specialized instruments.
Intraoperative fluorescent cholangiography (IFC) with concomitant fluorescent angiography is a recently developed method for non-invasive visualisation of the relevant anatomy during laparoscopic cholecystectomy. The objective of this study was to assess the time required by routine-use of IFC and to evaluate success-rate of the procedures. Methods Thirty-five patients scheduled for laparoscopic cholecystectomy and operated by the same surgeon were consecutively enrolled. A standardized protocol with IFC including concomitant angiography was performed during laparoscopic cholecystectomy. Intra-operative time-registration and exposure of predefined anatomical structures were recorded.
Laparoscopic Cholecystectomy applied to Artificial pneumoperitoneum and the extent of Surgical stimulation cause the wave of hemodynamics increase vigorously, which make it difficult to judge the depth of anesthesia according to traditional hemodynamics index such as heart rate and blood pressure.In case of this, the investigators design this research to study the Closed-Loop Target Controlled Infusion to anaesthesia of individualization guided by a Narcotrend index monitor in Laparoscopic Cholecystectomy.
Analgesic efficacy of multi-modal analgesia is superior to standard analgesia for patients undergoing elective laparoscopic cholecystectomy for symptomatic cholelithiasis. Topical cystic plate and port-site incision 0.25% bupivacaine significantly reduces pain after laparoscopic cholecystectomy.
The burden of iatrogenic bile duct injury (BDI), the most feared complication of laparoscopic cholecystectomy (LC), is extremely high and the repercussions on the patient's outcomes may be severe ranging from intraoperative repair to liver transplant or patient's death. Different techniques have been proposed to prevent BDI. Our hypothesis is that a fluorescence-based Imaging would allow visualization of the biliary tree anatomy as good as with the Intraoperative Cholangiogram with several main advantages: 1. ease of use 2. lack of invasiveness 3. absence of ionizing radiation to the patient and the operating staff 4. performed prior to any dissection (prior to "critical view of safety") Capacity of enhanced-reality based on virtual cholangiography (computer treatment of MRI images) to guide biliary tree anatomy visualization will be also evaluated in this study. The study requires a 2-month patient participation.
Minlaparotomy (MC) and laparoscopic cholecystoctomy (LC) are commonly applied surgical techniques for the management of symptomatic gallstone disease and both techiques have shown to be feasible for day surgery. However, to our knowledge the long-term outcome between these approaches has not been compared in randomised trials as day surgery procedures.
This is a study of new technology to allow gallbladder removal through a single small surgical incision. A surgical robot is utilized to help navigate the small space. In this study, patient characteristics are broad to assess how applicable the procedure is to everyone.
This study aims to evaluate post-operative pain in single-incision laparoscopic cholecystectomy (SILC) versus the conventional four port technique (LC). The investigators hypothesize that SILC is non-inferior in post-operative pain.
Background Laparoscopic cholecystectomy is a very common procedure. Postoperative pain, especially around the umbilical port is dominating the first postoperative week. Single Incision Laparoscopic cholecystectomy (SILC) has been proposed to diminish postoperative incisional pain and improve cosmetic results, but results are not convincing and the risk of formation of an umbilical trocar-site hernia is not properly investigated. This study aimed to investigate the risk of umbilical trocar-site hernia formation after SILC vs. conventional 4-port laparoscopic cholesystectomy. Methods This is a cohort registry study with prospective questionnaire and clinical follow-up on 239 patients having a SILC from 1/1 2009 to 1/6 2011 vs. 478 mathed patients having a conventional laparoscopic cholecystectomy (consecutively from one month before and after SILC. They are matched for age, gender, date of operation, and surgeons skills (database from intraoperatively registered data). Primary endpoint is umbilical trocar-site hernia formation (operation for a umbilical hernia or clinical hernia). The H0 hypothesis is that there is not difference between SILC and conventional. Exclusion criteria are: death, operation for acute cholecystitis. The included patients will be sent a questionnaire asking for operation for a hernia in the area, suspicion of a hernia, and perioperative data that we do not have in the database. Futhermore those patients who suspect a hernia will be invited to aclinical exam by a medic to state the diagnosis. Furthermore we patients are asked to report if they have chronic pain and/or discomfort.
