The purpose of this study is to better understand how much energy (calories) these patients need before and after surgery and whether nutrition is related to recovery, complications, and overall outcomes.\n\nWho can participate?\n\nAdults (18 years and older) with head and neck cancer who are scheduled to undergo free flap reconstructive surgery at Tel Aviv Sourasky Medical Center may be invited to participate.\n\nWhat will participants do?\n\nParticipants will undergo several nutrition-related assessments before and after surgery, including:\n\nIndirect calorimetry tests, which measure how much energy the body uses. Body composition measurements using a non-invasive device. A questionnaire about food intake. Collection of routine clinical information, laboratory results, and recovery data from medical records.\n\nThe indirect calorimetry assessments will be performed before surgery, several days after surgery, before hospital discharge, and approximately one month after discharge.\n\nWhat are the possible benefits of the study?\n\nThe information obtained may help researchers better understand the nutritional needs of patients with head and neck cancer undergoing major surgery. This knowledge may improve nutritional care and recovery for future patients.\n\nWill participation affect medical care?\n\nParticipation in the study will not change the standard medical or nutritional care patients receive. Nutritional follow-up will continue according to routine clinical practice.\n\nHow will privacy be protected?\n\nStudy data will be stored in a coded form, and access will be limited to authorized study personnel. Personal identifying information will be kept separate from the research database.",[66,67,68,69],"Reconstructive Surgical Procedures","Free Tissue Flaps","Head and Neck Cancer","Perioperative Care","2026-08-06",{"date":72,"type":73},"2026-08-12","ACTUAL",{"date":75,"type":73},"2025-01-01",{"date":77,"type":60},"2026-09-30",{"name":5,"class":6},1]
