    As treatment for esophageal cancer, radiotherapy was the mainstream in the 1950s and 1960s; however, the 5-year survival rate was only 4.3%. Surgical treatment was introduced in the clinical field by K. Nakayama and other surgeons in the late 1960s, and the 5-year survival rate increased to over 20%. Thanks to improvements in diagnostic capability, resectable cases without preoperative irradiation increased in number. Then surgical treatment was performed first, followed by post operative irradiation. The 5-year survival rate improved to 30-40%, but recurrence of upper mediastinal and cervical lymph nodes could not be controlled. Three-field lymph node dissection was employed in the 1980s, after which the 5-year survival rate increased to 50-60%. Moreover, endoscopic resection (EMR, ESD) came to be employed in early esophageal cancer cases in which invasion is limited to the mucosal layer. With development of cisplatin, chemo-radiotherapy (CRT) had also been carried out extensively, and its 5-year survival rate is 30-40%.
    In esophageal cancer patients, elderly persons constitute a large number and patients who have double or triple cancers in other organs account for about 30%. This makes decision of treatment strategy for esophageal cancer extremely difficult. Further progress is desired in diagnosis and treatment of esophageal cancer.

    Introduction : Early diagnosis and early treatment are the best ways to improve cancer patient prognoses. We developed ELPS (endoscopic laryngo-pharyngeal surgery) as an endoscopic treatment for superficial pharyngeal carcinoma. However, ELPS has not been applied for cervical esophagus carcinoma because of the narrow working space. We developed a hybrid endoscopic surgery (ESD+ELPS) for borderline lesions between the cervical esophagus and hypopharynx. The purpose of this study was to examine the usefulness and effectiveness of endoscopic treatment for superficial carcinoma of the hypopharynx and cervical esophagus. Patients & Methods : One hundred and sixty-eight patients (265 lesions) of superficial carcinoma of the hypopharynx and nasopharynx were treated between Jan 2000 and Aug 2009 at our institution. Their clinical and histopathological data as well as long-term results were investigated. Results : The endoscopic treatment cases involved 233 lesions. Among these, EMRC (endoscopic mucosal resection by cap-method) was performed on 85 lesions and ELPS on 132 lesions. Hybrid endoscopic surgery (ESD and ELPS) was performed on 7 lesions, which involved both the hypopharynx and cervical esophagus. The overall survival rate at 3 years was 80.2% and at 5 years 66.0%. Cause-specific survival rate at 3 years was 96.6% and at 5 years 94.8%. Conclusion : The results indicated the usefulness and effectiveness of endoscopic treatment for superficial carcinoma of the hypopharynx and cervical esophagus.

    The ideal laryngeal surgical procedures are performed under local anesthesia so that the voice can be monitored during surgery. In our department, we have been performing videoendoscopic laryngeal surgery under local anesthesia using a flexible endoscope since October 2003. Here, we report on basic techniques together with certain special techniques used to date.
    In our department, the procedure is regarded as best suited for treatment of patients with vocal polyps and other protruding lesions. The procedure commences by incising the lesion using a scalpel and resecting with forceps. Flexible endoscopes fitted with an NBI system are useful for both qualitative diagnosis and confirmation of tumor margins.

    Transoral partial laryngopharyngectomy is one of the organ preservation treatments for laryngeal and hypopharyngeal cancer. Basically this procedure does not require tracheostomy and reconstructive surgery, which translates to reduced surgical invasion, lower rates of complication, and prompt recovery of swallowing function. In our unique treatment, we performed en bloc resection using a distending laryngoscope and rigid laryngeal endoscope, which provided a wide view of the operating area and wide working space for bimanual manipulation. Recently, the FK laryngopharyngoscope® has been introduced to afford a wider surgical approach for the laryngeal, hypopharyngeal and also oropharyngeal regions. Laparoscopic surgical instruments (3 mm in diameter), a suction coagulator and a hemostatic clip were used for cutting, coagulation, and hemostasis. Use of rigid devices in this operation enables easier mastery by otolaryngologists who are experienced in laryngomicrosurgery.
    To date, 38 cases of supraglottic and hypopharyngeal cancer (32 as initial treatment and 6 as salvage surgery) have been treated by this operation. For the 26 cases with more than 1 year follow-up, 3-year disease-specific survival, crude survival, and laryngeal preservation rates were 95%, 80% and 95%, respectively.
