Introduction
In cases of mild cholecystitis without intra-abdominal adhesions, laparoscopic surgery is completed in a relatively short time. The total duration—including general anesthesia induction, preoperative skin disinfection, establishment of pneumoperitoneum, specimen extraction, and postoperative recovery to consciousness—is approximately 90 minutes. However, when cholecystitis is severe and dense intra-abdominal adhesions are present, the operative time becomes highly variable; generally, the more severe the inflammation, the longer the surgery takes.
Currently, minimally invasive surgery for gallstones primarily refers to laparoscopic cholecystectomy, which is considered the gold standard for surgical treatment of gallstones.
When cholecystitis is mild and there is no intra-abdominal adhesion, laparoscopic surgery proceeds rapidly; cholecystectomy itself may take only about 20–30 minutes. However, the total operative time also includes general anesthesia induction, preoperative skin disinfection, establishment of pneumoperitoneum, specimen retrieval, and postoperative recovery until awakening—typically totaling approximately 90 minutes.
In cases of severe cholecystitis or dense intra-abdominal adhesions, the duration becomes less predictable; generally, more severe inflammation correlates with longer operative times. Particularly when dense adhesions involve the Calot’s triangle, cholecystectomy alone may require 1–2 hours, and total operative time may exceed 3–4 hours. For patients with calculous cholecystitis in whom laparoscopic cholecystectomy proves technically difficult or carries exceptionally high risk, timely conversion to open surgery is essential to avoid bile duct injury and its potentially serious consequences.
