[Endoscopic Ultrasound Drainage of the Gallbladder in Acute Cholecystitis in Patients at High Surgical Risk]

The standard treatment for acute cholecystitis is laparoscopic cholecystectomy. Alternative procedures are used for patients at high surgical risk. Percutaneous drainage is widely available. The alternative of transpapillary drainage of the gallbladder via the ductus cysticus has only limited prospects of success. With the widespread use of interventional endoscopic ultrasound and the development of new stent systems, endoscopic ultrasound gallbladder drainage has proven to be a safe and reliable procedure.

We retrospectively report on our experiences in 11 consecutive patients with endoscopic ultrasound gallbladder drainage in acute cholecystitis between December 2018 and January 2021.

11 patients with acute cholecystitis with a mean age of 84.5 years (70-95 years) are reported. All patients had severe general comorbidities or advanced abdominal tumours or a combination of these conditions. After interdisciplinary debate, the indication for interventional therapy was made. This was carried out in 9 cases by means of endosonographic drainage alone and in 2 cases by means of percutaneous and two-stage endosonographic drainage. Technical success was achieved in 10 cases (91%), clinical success in 9 cases (82%). In 2 cases there were procedural complications that led to the operation.

In the case of high surgical risks, endosonographic drainage of the gall bladder is a safe and definitive therapy. This can be performed alone or in combination with percutaneous drainage. Endoscopic ultrasound drainage is superior to percutaneous drainage alone, due to its lower complication rates and lower rates of necessary follow-up interventions. Therefore, in cases of relatively high surgical risk, endoscopic ultrasound drainage of the gall bladder should be preferred to percutaneous drainage, especially when definitive therapy is required.
