Post-pharyngo-laryngectomy fistula is a frequent surgical complication, resulting in delayed patient management and reduced quality of life. A recent study has shown that the appearance of a fistula can be detected early by measuring cytokines (particularly IL10) in postoperative drainage fluids. Resumption of feeding following this surgery varies between postoperative day 5 and postoperative day 15, depending on the team\'s habits. Early refeeding reduces the length of hospital stay and improves patients\' quality of life. The decision to refeed is currently made without any clinical or biological marker of the quality of pharyngeal suture healing. The idea of this study is that good initial healing (evidenced by low levels of inflammatory cytokine in drainage fluids) allows early refeeding without putting the patient at additional risk. Main hypothesis and research objectives Main hypothesis: the determination of cytokines in postoperative drainage fluids (FODP) could be a tool for screening patients at no risk of developing a fistula, and for whom early refeeding (as early as postoperative day 3) could be proposed without exposing the patient to an additional risk of developing a FODP. Study objectives Primary objective: to compare the rate of post-(pharyngo)-total laryngectomy fistula between an early refeeding strategy (3rd or 4th postoperative day) and a late refeeding strategy (current standard of care: 7th postoperative day) in a low-risk fistula group defined according to the level of inflammatory cytokines in drainage fluids on the second postoperative day. Secondary objectives To compare an early versus a late refeeding strategy for patients at low risk of fistula defined according to the level of inflammatory cytokines in drainage fluids on the second postoperative day for: * length of hospital stay, * evolution of nutritional status, * time to postoperative radio-chemotherapy, if indicated postoperatively, * improvement in quality of life, * post-operative complications other than pharyngeal fistula. Evaluation of different strategies left to the investigator\'s choice (continuation of antibiotic therapy, increased delay before resumption of feeding, early resumption of surgery) in the group of patients at high risk of fistula, based on the determination of postoperative cytokines in drainage fluids.
