Filter by:During laparoscopic surgery, muscle relaxants are often administrated in order to ensure acceptable surgical conditions. These drugs bind to receptors in the neuromuscular junction. The degree of muscle relaxation is monitored by use of an acceleromyography and at the end of surgery another drug - Neostigmine- is given to reverse the muscle relaxation. However,there may still be a blockade of up to 70% of the receptors. This partial muscle relaxation may result in muscle weakness, reduced balance and prolonged hospitalization. This study will describe changes in balance and subjective muscle weakness after laparoscopic surgery. The primary hypothesis is that sway area is increased 30 min after extubation compared to the preoperative value.
1. Methylene blue in laparoscopy use for tubal patency assessment 2. Methylene blue could have negative effect on sperm motility, oocyte granulosa cell and fertility. 3. tubal washing after Methylene blue administration could be effective in pregnancy rate after operation.
The purpose of this study on laparoscopic hysterectomy is to investigate postoperative pain. Patients are allocated to either deep neuromuscular blockade and low intra-abdominal pressure (8 mmHg) or moderate neuromuscular blockade and usual intra-abdominal pressure (12 mmHg). Primary hypothesis: Deep neuromuscular blockade and low intra-abdominal pressure (8 mmHg) reduces postoperative pain compared to moderate neuromuscular blockade and intra-abdominal pressure (12 mmHg).
Prospective randomized pilot clinical trial, with 3 arms and one year follow up. The study will include 60 patients, with a 1:1:1 ratio, 20 patients per group. In 40 patients a transumbilical single site incision will be performed with two different manners: single-port device SILS TM (Single Incision Laparoscopic Surgery), and flexible endoscope and accessory trocars in a single incision (FSIS-Flexible Single Incision Surgery). The third group is the control one, a conventional laparoscopic approach. The trial is designed as a pilot study to assess, as main objective, if these two endoscopic approaches have the same security and effectiveness in cholecystectomy. Hypothesis: Transumbilical approaches with single port and single incision with the flexible endoscope have the same efficacy and safety performing the endoscopic cholecystectomy. Objectives: Main objective: Assess whether both approaches are equally safe in its application to endoscopic cholecystectomy. Secondary objectives: Investigate the differences in the rate of conversion to open surgery between different surgical approaches. Investigate the differences in the rate of wound infection between the different surgical approaches. Investigate the differences in the rate of postoperative incisional hernias between different surgical approaches. Investigate whether there are differences in the rate of overall complications, all-cause mortality and the cost between different surgical approaches.
This prospective, double blind, placebo-controlled, parallel group study will be conducted in the first affiliated hospital of Sun yat-sen university in Guangzhou, China. Patients aged 18-65 (ASA I-II) undergoing elective gynecologic laparoscopic surgery with general anesthesia will be involved in this study. According to previous studies and our pilot trial, the sample size was estimated to be 120 subjects. All eligible patients will be randomly assigned to one of three groups: Group A (single parecoxib) receiving parecoxib 40mg at 30min before the end of surgery; Group B (multiple parecoxib) receiving parecoxib 40mg at 30min before the end of surgery, at 8h and 20h after the surgery, respectively, and Group C (Control group) receiving normal saline. All patients will be managed by a standard propofol-remifentanil based total intravenous anesthesia protocol. The incidence and intensity of shoulder pain at rest and with motion will be evaluated by an independent doctor blinding to medication and grouping using visual analog scale (VAS) at 6h, 24h and 48h postoperatively. Other types of pain (e.g. trocar wound and visceral pain), side effects (such as postoperative nausea and vomiting, itching, dizziness, and oversedation) will be assessed as well. At the end of the observation, the intensity of the maximum pain will be recorded, and the effect of shoulder pain on the four variables regarding to quality of life (activity, mood, walking and sleep) will be assessed using modified Brief Pain Inventory(BPI) questionnaire.
Although a significant amount of work has been done to validate simulators as viable systems to teach technical skills outside the operating room, the next necessary step is to integrate simulator training into a comprehensive curriculum. The purpose of this study is to develop and validate a comprehensive ex-vivo curriculum for laparoscopic colorectal surgery. This curriculum will include training on a virtual reality simulator, cognitive training and cadaver lab training. The investigators will assess the effectiveness of the curriculum by conducting a randomized single blinded controlled trial. The investigators will be comparing the technical performance of curricular trained and non-trained residents in the operating room, during a procedure on a patient. The investigators hypothesize that surgical residents who participate in the curriculum will have superior technical proficiency and cognitive knowledge relating to performing laparoscopic colorectal surgery compared to conventionally trained residents.
Study of Oxidative Stress Markers in order to assess whether there are differences between standard laparoscopic cholecystectomy vs single port cholecystectomy for uncomplicated cholelithiasis
Keyhole bowel surgery provides the patient with an improved outcome following surgery in comparison to more traditional surgery requiring a large cut. In order to further improve outcomes there are several variables that must be controlled before, during and after the operation. These variables are the correct pain relief, accurate control and measurement of the fluid that is given during the operation and the subsequent mobility following surgery. Previous research has already identified that an enhanced recovery program (careful control and structure to the patients journey) will reduce the length of stay and complications after an operation. Currently an integral part of the enhanced recovery program requires the use of an epidural (a thin tube in the spine) to provide continuous pain relief for up to 48 hours. Through research previously undertaken at the MATTU the investigators have shown that an epidural can lead to an increase in the length of stay and a delay in the return to normal bowel function. A reason for the use of an epidural is to suppress the stress response. The investigators aim to recruit patients from outpatient clinic undergoing keyhole bowel surgery in one unit and randomize them to receive one of two different pain relief methods after the operation. Patients will follow the same care as standard patients but their pain relief will differ between two already well established modalities. They will also receive different intravenous fluids. Blood will also be drawn at various intervals immediately after the operation for future analysis. The trial will be funded by the MATTU and will run for approximately 18 months. This trial will enable us to establish the stress response in the four groups and correlate it to the patient's outcome with an aim to refining the enhanced recovery program.
This prospective randomized study aims for determination whether focused simulator based laparoscopic camera training in novices can improve camera performance in an actual clinical situations in the same manner as traditional training in the OR does, especially considering efficient use of training time.
Patients with left-colon cancer will be randomized to laparoscopic or laparotomic operation. during surgery and for 6 days after operation, intestinal oxygen tension and ischemia-reperfusion injury markers will be evaluated to understand if pneumoperitoneum is associated with reduced splanchnic blood flow and ischemia-reperfusion injury.
