Filter by:The purpose of this study is to determine the advantages of single trocar cholecystectomy over standard laparoscopic cholecystectomy.
The purpose of this study is to determine the safety and efficacy of the Endograb system which is an internal laparoscopic retractor device. This retractor device is inserted into the abdominal cavity through one of the 5 mm trocars and obviates the need for a separate dedicated trocar for retraction. Therefore enables the reduction of the number of abdominal incisions in a laparoscopic operation.
Cholecystectomy is one of the most common general surgery procedures performed in the US today and is among top 10 procedures performed in U.S. hospitals annually, and biliary tract disease has been estimated to cost U.S. healthcare $5 billion/year. Laparoscopic cholecystectomy was introduced in the early 1990s and has become the standard surgical approach for the treatment of gallbladder disease. More than 500,000 cholecystectomy procedures are performed in the US every year. Laparoscopic cholecystectomy is now performed as an outpatient basis and is related to a very low complication rate. Laparoscopic cholecystectomy requires the use of multiple trocar incisions. Natural Orifice Translumenal Endoscopic Surgery(NOTES) is a new type of surgical procedure currently being studied around the world. The idea of NOTES was developed several years ago in response to the concepts that patients would 1. realize the benefits of less invasive surgery by reducing the recovery time, 2. experience less physical discomfort associated with traditional procedures 3. have virtually no visible scarring following this type of surgery. All of these advantages have spurred research and investigation forward, encouraging physicians and researchers to develop new equipment and techniques to use during NOTES procedures. Although the Natural Orifice Translumenal Endoscopic Surgery approach may hold tremendous potential, there are many issues that need to be addressed before this technique is introduced into clinical care. The purpose of this study is to determine the safety, feasibility and short-term clinical outcomes (Phase I trial) of transvaginal NOTES cholecystectomy in female patients with symptomatic cholelithiasis and compare it to Laparoscopic Cholecystectomy (Phase II). Hypothesis 1: Transvaginal NOTES cholecystectomy is safe and feasible in female patients with symptomatic cholelithiasis. Hypothesis 2: The short term outcomes of Transvaginal NOTES cholecystectomy are comparable to Laparoscopic Cholecystectomy in female patients with symptomatic cholelithiasis. Aim 1: Determine the safety of Transvaginal NOTES cholecystectomy. Aim 2: Determine the feasibility of Transvaginal NOTES cholecystectomy. Aim 3: Determine the short-term outcomes of Transvaginal NOTES cholecystectomy. Aim 4: Compare the short-term outcomes of Transvaginal NOTES cholecystectomy to Laparoscopic cholecystectomy.
The investigators aim to investigate the safety, feasibility and short-term outcomes of Single Incision Laparoscopic Cholecystectomy. The investigators hypothesize that Single Incision Laparoscopic Cholecystectomy is safe and feasible.
The aim of the study is to investigate if P6 acupuncture made after induction of general anaesthesia might be effective for the prevention of PONV as ondansetron and if the acupuncture-ondansetron combination could enhance single therapy efficacy in patients undergoing laparoscopic cholecystectomy.
Laparoscopic surgery being performed with only one small incision via the umbilicus (belly button).
The physiological changes and postoperative pain are directly related with the degree of intra-abdominal pressure kept during the laparoscopy. The present study aims to examine difference between low pressure pneumoperitoneum (8 mm Hg)and High pressure pneumoperitoneum (12 mm Hg)during laparoscopic cholecystectomy in terms of pain, cardio-pulmonary function, arterial blood gas changes etc.
The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.
Case matched study on 50 consecutive patients undergoing robotic assisted cholecystectomy (Da Vinci Robot, Intuitive Surgical). These patients are matched 1:1 to 50 patients with conventional laparoscopic cholecystectomy, according to age, gender, ASA score, histology and surgical experience. - Trial with surgical intervention
This is an observational study of pain and outcomes from patients undergoing transgastric NOTES removal of their appendix or gallbladder. Subjects who elect to have a transgastric NOTES removal of their appendix or gallbladder and agree to be in this study (through signature on the informed consent form) will be followed per standard of care, with additional follow-up for data collection including the following: - Subjects will complete a 7 day pain/temperature log after surgery - Subjects will receive a phone call at 6 months and at 1 year after surgery to capture data related to safety, adverse events, hospitalizations and patient satisfaction Additional data related to pain and outcomes will be collected at baseline/screening and at follow-up as necessary.
