Minimally invasive surgery, gastrointestinal cancer has become more mature treatment, and involve various specialist areas. However, minimally invasive surgery because of gastrointestinal malignant tumor specificity, the gastrointestinal tract the actual role of minimally invasive surgery, minimally invasive surgical indications and were being questioned radical, the biggest concern is not complete tumor resection and abdominal incision and intraperitoneal metastasis extensive metastasis. Abdominal incision caused mainly due to metastasis of tumor cells to escape operation, carbon dioxide pneumoperitoneum disseminated cancer cells, a cell window hematoma and removal of specimen trap cancer cells to escape and so on.
Gastrointestinal Endoscopic minimally invasive surgery consists of resection of the stomach and the King film laparoscopic gastrectomy. Minimally invasive endoscopic surgery in early stage gastric cancer is technically more mature, and its indication for the stomach under King film, or to teach film that is well differentiated carcinoma, no ulcer, swelling, lesions smaller than 2 cm in diameter, depressed lesion diameter less than 1 cm were. But the problem of multiple lesions of early gastric cancer, lymph node metastasis before minimally invasive surgery to determine the difficulties, the lesions are violations of lymphatic vessels, are the gastric safety of minimally invasive surgery obstacles to implementation.
Laparoscopic colorectal surgery in the early 90s, including full-assisted laparoscopic surgery and laparoscopic surgery two. Because laparoscopic colorectal surgery can not press the palpable lesion, so the positioning of the primary tumor would be difficult, omissions, while tumors of the colon may increase. To prevent this from happening, often in need of intraoperative colonoscopy position. In short, minimally invasive surgery, gastrointestinal cancer was carried out in recent years, the accumulation of cases is not much follow-up time is short, so the long-term efficacy remains to be demonstrated. The prospect of minimally invasive surgery of gastrointestinal tumors depends on the surgical complications, tumor recurrence scientific assessment of efficacy.
