Filter by:Pancreaticobiliary reflux has been found in patients with cholelithiasis and gallbladder cancer associated with normal pancreaticobiliary union. However, the presence of pancreaticobiliary reflux has not been studied in patients without gallstones (healthy gallbladders). The authors believe that pancreaticobiliary reflux might be a normal phenomenon in patients with and without gallstones, although in patients with cholelithiasis it might constitute a pathological condition associated with dismotility of the biliary tree and the sphincter of Oddi.
While there exists consensus among surgeons that patients with gallstone pancreatitis should undergo cholecystectomy to prevent recurrence, the precise timing of laparoscopic cholecystectomy for mild to moderate disease remains controversial. We hypothesize that laparoscopic cholecystectomy performed within 48 hours of admission, regardless of resolution of abdominal pain or abnormal laboratory values, will result in a shorter hospital stay.
The purpose of this study is to determine the effects of intraperitoneal administration of levobupivacaine on pain after laparoscopic cholecystectomy.
The purpose of the study is to determine the feasibility of cholecystectomy made by a transvaginal approach with a NOTES procedure (natural orifice translumenal endoscopic surgery).
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.
