Clinical Trial Summary

In this new era of less invasive procedures, the indications for endoscopic ultrasound (EUS)-guided gallbladder drainage (GBD) are rapidly expanding. Nowadays, the standard treatment for uncomplicated cholelithiasis (symptomatic patients not requiring hospital admission or non-surgically managed during one or more hospital admissions) is elective laparoscopic cholecystectomy. To avoid the complications, difficulties and disadvantages of cholecystectomy, the investigators proposed a single-center study to determine the safety and effectiveness of EUS-guided GBD with electrocautery-enhanced lumen-apposing metal stent (LAMS) (Boston Scientific, Marlborough, MA, EEUU) with stone removal in patients with cholelithiasis, in comparison with the gold standard treatment, the elective laparoscopic cholecystectomy.


Description:

Currently, elective laparoscopic cholecystectomy (LC), is the preferred management for cholelithiasis in patients with history of gallstones-related adverse events, increased risk for gallbladder cancer, or recurrent typical biliary colic. Although elective LC is a commonly performed surgery, the incidence of serious adverse events is around 2.6%. Also, post-cholecystectomy syndrome, alkaline reflux gastritis and bile duct injury are chronic and feared adverse events secondary to gallbladder removal. To avoid them, a more conservative approach need to be address. The preservation of the gallbladder permits the conservation of its physiological functions, preventing LC adverse events, with potential less recovery time. In this scenario, the endoscopic ultrasound (EUS) with lumen-apposing metal stent (LAMS)-assisted cholecystostomy for gallstones clearance has gained popularity due its trend toward an improved safety profile. The increased on advanced endoscopy experience along with the development of new stents, tools, and delivery systems, had placed the EUS-guided cholecystostomy as a plausible alternative to elective LC for acute cholecystitis, high-risk surgical patients, or patients with a concomitant bile duct neoplasia. In those contexts, EUS-guided cholecystostomy has demonstrated similar or even less hospitalization length of stays, adverse events, readmissions and reinterventions in comparison with elective LC or percutaneous drainage, respectively. Thus, the feasibility of EUS-guided cholecystostomy for cholelithiasis deserves to be explored. This study pursues to compare between the effectiveness and safety of EUS-guided cholecystostomy and the elective laparoscopic cholecystectomy through an interventional, two group assignment, controlled trial.

Intervention

Procedure:
LAMS placement for cholecystostomy
The EUS-guided cholecystostomy entails placing a 10 mm x 10 mm or 10mm x 15mm Electrocautery-Enhanced LAMS for direct cholecystoscopy with a transnasal gastroscope. Then, the cholecystostomy will be performed with an echoendoscope, assisted by fluoroscopy to allow the puncturing of the gallbladder form either the duodenal bulb (cholecysto-duodenoscopy) or the gastric antrum (cholecysto-gastrostomy). Subsequently, from the most optimal anatomic point it will be tutored with a 10mmx10mm or 10mm x 15mm LAMS to create anastomosis between the structures. Then, the stone clearance will be performed by endoscopy (basket catheters) or by cholangioscopy (mechanical lithotripsy with or without basket catheters).
Laparoscopic cholecystectomy
A laparoscopic biliary exploration along with an elective laparoscopic cholecystectomy will be performed by experienced laparoscopic surgeons (over 100 laparoscopic procedures yearly) by three or four-trocar technique with transection of the cystic duct and artery.
