A 76-year-old woman presented at the emergency department with severe abdominal pain. Two years prior, she had been diagnosed with rectal cancer with multiple lung metastasis. Abdominal CT revealed the presence of an impacted calcified gallstone within the narrow segment of the rectal cancer. Initial attempts to remove the stone using a mechanical lithotripter were unsuccessful due to the stoneʼs exceptional hardness. Consequently, an innovative approach was employed, utilizing a Holmium-Yttrium Aluminum Garnet (Ho-YAG) laser to fragment the gallstone, followed by complete removal of the stone fragments with a retrieval net. In conclusion, endoscopic treatment including the lithotripsy with the Ho-YAG laser may be considered before a surgical intervention.
