Performing a laparoscopic cholecystectomy requires an exploration of the abdominal cavity, which is used to assess what is going on inside the abdominal cavity and whether minimally invasive laparoscopy can be performed. Laparoscopic cholecystectomy begins with general anesthesia of the patient, followed by injection of carbon dioxide into the abdominal cavity to create a pneumoperitoneum, and an exploration of the abdominal cavity to initially assess the intra-abdominal cavity and the possibility of minimally invasive laparoscopic surgery. Cholecystectomy is performed if there are no other intra-abdominal lesions, and if there are other lesions (e.g., intra-abdominal adhesions) they can be detected during the laparotomy and treated. Laparoscopic cholecystectomy with exploration of the abdominal cavity is routine and plays an important role in avoiding missed lesions. If the intra-abdominal cavity is complex, open surgery is required, and if other lesions (e.g., tumors) are present, they need to be treated.
