[Analysis of the effect of linear stapler closure pharyngeal after total laryngectomy].
To compare the effect of closure of pharyngeal cavity with linear stapler and manual suture in total laryngectomy. A retrospective study was conducted on 32 patients who underwent total laryngectomy with linear stapler to close the pharyngeal from December 2014 to March 2019. Among them, 25 patients used closed technique and 7 patients used open technique. At the same time, 23 patients who underwent total laryngectomy with manual suture the pharyngeal by the same operator from January 2010 to December 2014 were collected. The clinical parameters of the two groups were compared and analyzed. Compared with the control group, the closed technical group had no significant difference in terms of gender, diabetes mellitus, second surgery, T stage, and surgical method（> 0.05）. While the age （63.60 ± 9.46） years and （54.35 ± 11.13） years , operation time （239.67 ± 88.43） min and （474.35 ± 140.16） min , oral feeding time （12.84 ± 3.65） min and （17.3 ± 9.71）min , hospitalization days after operation （ 15.48 ± 3.78） d and （20.22 ± 10.14） d, incidence of Pharygocutaneous fistula 4.0% （1/25） and 26.1% （6/23）, had significant statistical differences （ 0.05），while there was a statistically significant difference in diabetes mellitus, second surgery, and operation time （<0.05）. The linear stapler closed closure technique can reduce the incidence of Pharygocutaneous fistula, shorten the operation time and oral feeding time, and reduce the length of hospital stay.Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.
