Minimally invasive laparoscopic surgery in surgical oncology has been carried out very commonly and developed very rapidly in recent years, which is a development trend of surgical oncology. Abdominal surgery, such as gastric cancer, colon cancer, rectal cancer, retroperitoneal tumor, and gastrointestinal mesenchymal tumor can be treated by laparoscopic surgery. Some contraindications of laparoscopic surgery are mainly when the tumor has obvious external invasion, late tumor stage, and cannot be cut cleanly under laparoscopy, do not force laparoscopic surgery. Minimally invasive laparoscopic surgery can also be used for thoracic tumors, such as laparoscopic minimally invasive treatment of lung cancer, laparoscopic minimally invasive treatment of esophageal cancer, laparoscopic minimally invasive treatment of mediastinal tumors, such as thymic tumors, mediastinal thyroid tumors, mediastinal nerve tumors and fibroids. For example, patients with malignant pleural fluid can be treated laparoscopically by local excision of pleural dissemination foci or fixation of the chest cavity. Patients with postoperative gastric cancer and suspected metastases from abdominal implants can likewise be reviewed laparoscopically for final staging after surgery.
