Filter by:Uncomplicated laparoscopic cholecystectomy will in most patients result in moderate to severe pain until the first postoperative day. This will subside during the second and third postoperative day [1]. A feeling of low general well-being will also be present until the first postoperative day and subside during the next couple of days [2]. To achieve faster recovery after laparoscopic interventions it has been shown that a reduction in the size of laparoscopic ports and thereby incisions can reduce postoperative pain [3,4]. A new minimal invasive surgical technique is based on the principle of completely eliminating the use of ports through the abdominal wall. This new technique is called Natural Orifice Transluminal Endoscopic Surgery (NOTES) and is defined by acquiring minimal invasive access to the abdominal cavity through the body's natural openings like the mouth and stomach, anus, urethra and vagina. With the NOTES technique one can completely avoid incisions in the abdominal wall and thereby reduce the surgical trauma. The benefits of this technique is a reduction of postoperative pain, elimination of incisional hernias, prevention of wound infections, reduction of peritoneal adherence formation, achieving a faster recovery and a better cosmetic result [7,8]. The most documented and well-described way for gaining NOTES access to the abdominal cavity is through the vagina, transvaginal (TV). TV NOTES has mainly been used for cholecystectomy because of the direct line of vision to the upper abdomen and gallbladder that is achieved through this opening. Compilation of results show that TV NOTES cholecystectomy can be implemented with low complication rates [20-22]. One retrospective case-control and one prospective observational study report less postoperative pain, reduced consumption of analgesics and faster recovery for TV NOTES compared to conventional laparoscopic cholecystectomy [23,24]. To date there are no systematic prospective randomized data on whether or not TV NOTES cholecystectomy leads to a better surgical outcome. In the present study the postoperative course after TV NOTES cholecystectomy will be compared to laparoscopic cholecystectomy in a prospective randomized and blinded trial. The outcome of the randomization between the two surgical techniques will be blinded to patient and the nurse staff for the first 72 hours after the operation. The primary outcome parameter will be postoperative pain score during the first 24 hours. Secondary outcome parameters are postoperative pain score for the first 72 hours, fatigue, well-being, nausea, consumption of analgesics, complications, cosmetic result and sexual function. The hypothesis being that TV NOTES cholecystectomy gives less postoperative pain, fatigue and nausea, a reduction in analgesics and a better cosmetic result and general well-being than conventional 4 port laparoscopic cholecystectomy.
This study will compare Single Incision Laparoscopic Surgery (SILS) cholecystectomy to traditional laparoscopic cholecystectomy (LC), focusing on patient-reported outcomes and cost.
To determine the feasibility, safety, and efficacy of a novel minimally invasive approach to cholecystectomy and to establish a description of this novel translumenal technique in humans at this institution.
This study proposes to evaluate the ability to reduce the size and number of laparoscopic incisions required to perform gall bladder removal by using flexible endoscopic instruments introduced through the mouth, into the stomach and through the stomach wall.
This study is designed to assess whether a new technique called facilitated endoscopic retrograde cholangiopancreatography (ERCP) is or is not superior to conventional ERCP for removing stones found in the bile duct at the time of laparoscopic cholecystectomy. ERCP is an endoscopic procedure used to facilitate the radiological examination and subsequent manipulation of the common bile duct (eg. opening it up, which is called sphincterotomy). Both facilitated and conventional ERCP are performed as a separate procedure after the initial gallbladder surgery. This is a comparative study of these two techniques in a randomised clinical trial. The aim of this randomised clinical trial is to enable surgeons to decide whether placement of a plastic stent at the time of laparoscopic cholecystectomy will improve the success rate and safety of subsequent ERCP and sphincterotomy.
The purpose of this study is to determine the effectiveness and safety of using the Medstone lithotripter to treat single non-calcified gallstones from 4 to 20 mm in diameter.
