CLE is known as “optical biopsy” and compared with other endoscopic techniques, it has obvious advantages. CLE systems include probe-based confocal laser endomicroscopy (pCLE) and endoscope-based confocal laser endomicroscopy (eCLE). Since 2006, CLE has been widely used for the evaluation of various lesions in the digestive system, including esophageal, gastric, and colonic neoplasia, pancreatic cysts and solid lesions, and inflammatory bowel disease. The advent of CLE has made in vivo microscopic imaging possible, which has changed the endoscopic screening and diagnosis of multiple gastrointestinal (GI) lesions. However, the value of its use in GI diseases is still controversial. In this review, we focus on the application of CLE in the field of esophageal diseases.展开更多

Laryngotracheal flap was used in hypopharyngaesophageal reconstruction for 26 elderly patients with advanced pyriform sinus cancer Pharyngocutaneous fistula developed in 5 patients and healed spontaneously without further surgery. Full diet was resumed in all the patients. The surgical technique and its advantages and disadvantages are discussed. The laryngotracheal flap in the reconstruction of hypopharyngoesophageal defect for elderly patients is a procedure of choice.展开更多
