Although endoscopic retrograde cholangiopancreatography followed by cholecystectomy remains widely practiced, growing evidence supports the transcystic approach as a safe, minimally invasive, and cost-effective alternative.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We present a standardized, step-by-step description of the laparoscopic transcystic technique developed through our experience in over 100 consecutive patients. The procedure is detailed, including the management of specific intraoperative scenarios. Technical tips and tricks are provided to optimize performance in cases of narrow cystic ducts, impacted or large stones, prior biliary prostheses\u00a0and complex inflammatory conditions. In addition, we developed a learning-curve modeling framework to quantify how surgical experience influences key outcomes and to estimate the procedural volume required to achieve reproducible and acceptable results in other centers adopting this technique.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The standardized technique proved feasible and reproducible across a broad range of clinical presentations. The transcystic approach allowed successful clearance of the bile duct in the vast majority of patients.
