6 Clinical Trials for Various Conditions
This is a prospective, non-randomized study of 50 people with suspected biliary dyskinesia. The purpose of this study is to investigate if it is possible to use ultrasound to make a diagnosis of a condition called biliary dyskinesia. The investigators null hypothesis is that there will be no statistical difference between the proposed experimental test (Ultrasound) and the HIDA scan (a nuclear medicine hepatobiliary system scan) in the diagnosis of biliary dyskinesia.
This study will compare Single Incision Laparoscopic Surgery (SILS) cholecystectomy to traditional laparoscopic cholecystectomy (LC), focusing on patient-reported outcomes and cost.
The goal of this study is to evaluate the utility and efficacy of an artificial intelligence (AI) model at identifying structures and phases of surgery compared to traditional white light assessment by trained surgeons. Surgeons will perform the procedure in their standard practice, while the AI model analyzes data from the laparoscopic camera. Surgeons will be asked to audibly state when they identify structures and enter different phases of the surgical procedure. The AI will not alter the surgeon's view or be visible to the surgeon, and the surgeon will perform the procedure in the exact same fashion as they typically do.
Benign gallbladder disease, including acute cholecystitis, chronic cholecystitis, biliary dyskinesia, and biliary colic, is very common, with over 300,000 surgical cholecystectomies performed per year in the US. Unfortunately, complication rates in elderly patients or patients with many comorbidities are high. These patients are often managed with percutaneous tube drainage of the gallbladder (percutaneous cholecystostomy). The recurrence rate of calculous cholecystitis after cholecystostomy tube removal is as high as 35% at 1 year. These patients are thus faced with permanent cholecystostomy tube drainage, high-risk surgery, or cholecystostomy tube removal and risk of repeat cholecystitis. Gallbladder cryoablation is an alternative to surgical cholecystectomy which is performed percutaneously and does not require general anesthesia. Published evidence on the outcomes of gallbladder cryoablation is however limited at this point in time. The purpose of the proposed study is to follow the outcomes of high-risk patients who undergo gallbladder cryoablation.
Natural Orifice Translumenal Endoscopic Surgery (NOTES) describes a new field of investigational surgery which uses the endoscope as the primary operative tool. The insertion sites for the endoscope include natural orifices such as the mouth, anus, vagina, or urethra. Multidisciplinary teams of surgeons and gastroenterologists collaborate to develop safe and effective surgical techniques via the natural orifice route in order to avoid surgical incisions. Early studies have focused on transvaginal surgery as the access route to the abdomen as it sidesteps troubling questions about infection and closure of the organ. This study is a pilot study to test the feasibility to NOTES transvaginal cholecystectomy using conventional surgical and endoscopic tools.
Prospective randomized trial of single incision versus standard 4 port laparoscopic cholecystectomy. Hypothesis is that the operative time will be longer with single incision.
