EUS gallbladder (GB) drainage technique started in 2007 when the double-pigtail plastic stents or nasocystic drainage tube was used for the drainage. Subsequently, therapeutic EUS has evolved, especially with the introduction of the electrocautery-enhanced lumen-apposing metal stent (EC-LAMS) for the treatment of GB stones.[1,2]
An 83-year-old woman with Alzheimer’s disease and hypertension was addressed to our evaluation because of symptomatic GB stones. A computed tomography scan revealed the presence of multiple stones <1 cm into the GB in the absence of dilation and stones into the common bile duct. The case was discussed during our multidisciplinary meeting, and an EUS plus EC-LAMS with 2-month removal was proposed. We performed a freehand cholecystogastrostomy (CGS) under EUS guidance from the anterior wall of the gastric antrum with a 10 mm × 20 mm Hot-Spaxus™ (Taewoong Medical Co., Gimpo, Korea)[3-5] [Figure 1]. After EC-LAMS placement, no balloon dilation was performed and no double-pigtail plastic stent was placed. The stent was placed with the aim to obtain a spontaneous stone migration into the gastric cavity [Video 1]. At 1 month, the patient underwent esophagogastroduodenoscopy showing the correct placement of the stent with only one stone inside. At 2 months, with a pediatric gastroscope, we explored the GB that was empty from stones and the stent was easily removed by a standard gastroscope and tooth-rat forceps. No plastic pigtail stents were placed across the CGS. The patient was followed for 6 months after stent removal, and no early and late adverse events were experienced. In our opinion, probably, in future, the elective GB treatment of symptomatic stones should be a valid alternative in the elderly or unfit for surgery patients [Video 1].
