Introduction of the Department of Endoscopy (DE)
Endoscopic Surgery of Sun Yat-sen University Cancer Center was merged by Endoscopy Room and Laser Surgery in 1999. The Department adheres to “standardization, innovation and service” as its aim of work and idea of development. It is deeply rooted in the standardized endoscopic operation, diagnosis and treatment and derives its impetus from technological innovation. It persists in improving its services to both patients and the Hospital. It promotes the development of diverse endoscopic diagnosis and treatment techniques of tumor by combining the characteristics of the Hospital and specializing in its key characteristic diagnosis and treatment with endoscopic ultrasonography. The Department is one of the earliest departments to have treated malignant tumors with laser-mediated photodynamic therapy nationwide. It has abundant experience in treating early and advanced esophageal cancer, lung cancer, rectal carcinoma and nasopharyngeal carcinoma.
The Department is equipped with the most advanced worldwide Japanese Olympus. Recently every year, the Department of Endoscopic Surgery regularly fulfills over 20,000 cases of ordinary and painless endoscopy (including gastroscopy, enteroscopy, endoscopic ultrasonography, bronchoscopy and laryngendoscopy) for diagnosis and treatment; completes over 3,000 cases of endoscopic ultrasonography targeted at pancreatic tumor lesions, retroperitoneal tumor lesions, mediastinal tumor lesions and pelvic tumor lesions; finishes over 1,000 cases of cytopathological diagnosis for EUS-guided fine-needle aspiration (EUS-FNA) targeted at gastrointestinal and surrounding organ lesions; succeeds in 1500 cases of EBUS-guided fine-needle aspiration (EBUS-FNA) biopsy. It is top-ranked nationwide in its number of diagnosis and treatment cases. The EUS-FNA and EBUS-TBNA cytopathological diagnoses of the Hospital reach an accuracy of above 80%.
In terms of teaching and scientific research, the Department was certified by Ministry of Health to become its technical training base for endoscopic diagnosis and treatment of digestive system and respiratory system in 2007. So far, it has cultivated more than 220 endoscopy physicians for hospitals of all levels. Besides the characteristic clinical diagnosis and treatment, the Department has carried out clinical and research work on benign and malignant pancreatic tumors and biliary tract neoplasms using the mature diagnosis & treatment technology of endoscopic ultrasonography and pancreatic & biliary endoscopy. In the aspect of upper gastrointestinal tract cancer, it has mainly researched related endoscopic diagnosis of early gastric carcinoma and early esophagus carcinoma. In the aspect of large bowel neoplasm, it has studied the precancerous lesions of colorectal cancer and early diagnosis & treatment of colorectal cancer through the fecal occult blood screening for colorectal cancer, and conducted the follow-up prospective study of postoperative colonoscopy of colorectal cancer and adenomatous polyp as well as the follow-up study of colorectal cancer colonoscopy in the high-risk group. In the past few years, the Department has taken up 8 projects at the provincial & ministerial level and above and published over 30 papers both at home and abroad, including 2 papers on the international top-notch journals of endoscopy. Currently in the Department there are 1 chief physician, 5 associate chief physicians, 4 attending physicians, 4 resident physicians and 15 nurse practitioners and technicians, 29 in total.
The characteristic techniques of diagnosis and treatment include:
(1) The technique of painless digestive endoscopy which alleviates the pain during gastroscopy and enteroscopy and facilitates various operations for endoscopic treatment;
(2) The techniques of endoscopic ultrasonography and EUS-guided fine-needle aspiration (EUS-FNA) which can determine the nature of intestinal submucosal lesions, judge the invasion depth and scope of malignant digestive tract tumor and diagnose the pancreatic diseases, etc.;
(3) The techniques of endobroncheal ultrasonography and EBUS-TBNA which were recommended in 2007 by the international lung cancer guidelines as the important tool to treat the staging of lung cancer and which are mainly used to diagnose and analyze the staging of lung cancer lymphatic metastasis, enlargement of thoracic lymph nodes as well as the mediastinal tumor and pulmonary tumor;
(4) The technique of esophageal dilatation for postoperative anastomotic stricture which plays an important role in treating esophageal strictures and obstructions caused by benign and malignant esophageal diseases;
(5) The technique of stent implantation in the digestive tract which can improve the life quality of patients with advanced esophageal carcinoma;
(6) The techniques of endoscopic retrograde cholangiopancreatography (ERCP) and ERBD for benign and malignant biliary strictures or obstructions which provide a safe and effective minimally invasive therapy for patients with pancreaticobiliary diseases and avoid open surgery;
(7) The techniques of gastrointestinal endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for precancerous lesions of intestinal cancer and gastric carcinoma or the early gastric carcinoma and intestinal cancer;
(8) The techniques of the high-frequency electric resection & coagulation and nylon endoloop ligature for treating gastrointestinal polyps which play an important role in early detection and removal of various polyps and prevention from cancerization of polyps;
(9) The techniques of percutaneous endoscopic gastrostomy (PEG) and endoscopic nasojejunal tube placement which provide the enteral nutrition for patients with postoperative gastroparesis and incapable of eating after clinical surgery;
(10) The technique of preoperative localization of gastrointestinal tumor;
(11) The techniques of endoscopic hemostatic therapy (titanium clip hemostasis, submucosal injection, argon plasma coagulation, microwave coagulation therapy, high-frequency electrocoagulation therapy, hemostatic drug spraying, etc.) which can swiftly and effectively control the gastrointestinal bleeding of patients.
