Linear stapler closure of the pharynx during total laryngectomy: a 15-year experience (from closed technique to semi-closed technique).
Personal experience in performing linear stapler closure of the pharynx during 70 total laryngectomies is reported. Laryngeal staplers (55 and 60 cm) with an angled handle were used, permitting vertical closure with 19 or 20 metal staples in a double row. A closed technique was initially used, but, over the years, this has gradually been replaced by the semi-closed technique to avoid trapping the suprahyoid part of the epiglottis between the jaws of the stapler. The stapler is inserted below the larynx after having separated it from all muscular and neurovascular connections, and after performing a mini-pharyngotomy at the vallecula epiglottica in order to extract the epiglottis, evert it ventrally and suture it to the hyothyroepiglottic space. The jaws of the stapler are closed and the staples are fired while the flaps of the mini-pharyngotomy are raised above the jaws. The scalpel is inserted above the stapler to remove the larynx. When the stapler is opened, the vertical linear suture of the pharynx is evident and can be examined. This procedure takes only a few minutes to perform. It guarantees a long-term stable watertight closure, dramatically reduces contamination of the operating field by pharyngeal secretions, and permits rapid healing time, greatly lowering patient management costs. In the cases presented here, there was a 1.8% rate of pharyngocutaneous fistulae in patients who were not radiated, whereas the rate was 13.1% in pre-radiated patients. In agreement with the international literature, this procedure does not increase the rate of fistulae and, in fact, it seems to reduce it. Moreover, it is particularly indicated for pre-radiated patients. Nevertheless, the Authors recommend reserving this type of procedure to cases in which, based on meticulous pre-operative assessment by means of endoscopy and imaging, the endolaryngeal site of the tumour has been assessed and there is no need for peri-operative exploration of the pharynx or tongue base.
