Transoral en bloc resection of superficial laryngeal and pharyngeal cancers

Abstract

Our transoral en bloc resection technique can be easily adopted, and it effectively maintained QOL after treatment.

Endoscopic laryngo-pharyngeal surgery for superficial laryngo-pharyngeal cancer

“…It has been reported that TLM for laryngo-pharyngeal cancer results in an excellent organ preservation rate [11,12]. However, because of the limitation of the surgical field, the tumor has to be divided into piecemeal specimens during resection of a large-size tumor [17], which may increase the potential for local recurrence. TORS is an innovative treatment option which is quickly spreading worldwide.…”

A prospective clinical trial of the second‐look procedure for transoral surgery in patients with T1 and T2 laryngeal, oropharyngeal, and hypopharyngeal cancer

“…Straight operation field surgeries such as TOVS and TLM provide easy maneuverability in a similar manner to that of the laryngo‐microsurgery technique, while TORS allows a better view and increased precision, especially when working in less‐accessible areas . The common demerits of these techniques include the limited view and working field . TOS aims for definitive resection with minimum safety margins that may contribute to organ and function preservation.…”

“…Endoscope-assisted surgeries, such as TOVS, TORS, and ELPS, afford precise views that allow resection to be completed with minimal invasiveness. [4][5][6][7][8]10 Straight operation field surgeries such as TOVS and TLM provide easy maneuverability in a similar manner to that of the laryngo-microsurgery technique, 6,[8][9][10] while TORS allows a better view and increased precision, especially when working in less-accessible areas. 4 The Note: Independent significant predictive factors were tumor depth by enhanced CT in primary endpoint 1 and poorly differentiation by pathological examination in primary endpoint 2.…”

“…Although most HNC patients present with advanced‐stage disease on their first visit, the number of early T‐stage patients has increased following the advent development of advanced diagnostic techniques such as positron emission tomography‐computed tomography (PET‐CT) and narrow‐band imaging (NBI) endoscopy, as well as because of an increased awareness of HNC among doctors in other fields . The development of surgical support instruments has promoted innovations in the field of minimally invasive surgery for the treatment of HNC, particularly with regard to definitive surgery in early T‐stage patients . Transoral surgery (TOS) is believed to derive equivalent outcomes as those of conventional (chemo‐)radiotherapy or open surgery; for example, total or partial laryngectomy, pharyngectomy .…”
