Percutaneous endoscopic cholecystolithotripsy offers an effective alternative for gallstone removal, achieving high stone-free rates. This minimally invasive procedure provides advantages over extracorporeal shock-wave lithotripsy for gallstone patients.

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery

Background:

  • Residual gallstones are common (up to 50%) after extracorporeal shock-wave lithotripsy (ESWL), even with oral dissolution therapy.
  • Alternative methods are needed to improve gallstone clearance rates and patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of percutaneous endoscopic cholecystolithotripsy (PECL) for gallstone removal.
  • To compare PECL with existing treatments like ESWL.

Main Methods:

  • Eleven patients (6 female, 5 male; aged 31-75) underwent PECL.
  • Gallbladder puncture via an anterior transperitoneal approach, tract dilation, and stone removal using a 21-F cholecystoscope.
  • Large calculi were disintegrated using ultrasound or electrohydraulic lithotripsy.

Main Results:

  • Eight patients were stone-free at 3 months; two had small residual stones.
  • Nine patients were stone-free at 6 months.
  • PECL demonstrated advantages including immediate stone removal, reduced pain, and shorter hospitalization.

Conclusions:

  • Percutaneous endoscopic cholecystolithotripsy is an effective procedure for gallstone management.
  • PECL offers significant benefits over ESWL, including higher clearance rates and improved patient recovery.
  • This technique represents a valuable option for patients with residual gallstones or those seeking alternatives to ESWL.
