Objective:To compare the effects of three heating methods on intraoperative temperature and postoperative resuscitation in patients undergoing three-incision radical resection of esophageal cancer under full endoscope.Methods:A total of 145 patients undergoing endoscopic three-incision radical resection of esophageal cancer were randomized to receive forced-air warming respectively on the under-body blanket(UB group, n=48), over-body blanket (OB group, n=48), underbody blanket in combination with over-body blanket(Combined group, n=49). The nasopharyngeal temperature were recorded at the time of entering the operating room, at the beginning of the intubation, at the beginning of the operation and every 30min after the operation, at the end of the operation. The incidence of hypothermia, hypothermia related adverse reactions and postoperative resuscitation indicators of the three groups were compared. Results:During the operation, the patients' temperature fluctuation showed two processes of decrease and two processes of increase. The temperature of Combined group showed a lower fall and a faster rise. The average temperature of the Combined group were higher than the other two group at each time point from the beginning of the intubation, the incidence of hypothermia was 4.08% (2/49), which was lower than the OB group [22.92% (11/48)] and the UB group [18.75% (9/48)], The difference was statistically significant ( χ2 value was 7.397, P=0.025). The temperature of the UB group was (36.52±0.18),(36.31±0.35)℃ at the beginning of intubation and at the end of the operation, respectively, which were higher than that of the OB group (36.44±0.15),(36.13±0.32)℃ ( t value was 2.393, 3.723, P < 0.05). The temperature comfort score of the combined group was 7.81±0.52, higher than that of the other two groups ( F value was 19.962, P<0.01), and the scores of chills, agitation and chills in the recovery period were lower than that of the other two groups ( F value was 8.186, 6.705, 4.051, all P < 0.05). The extubation time and the waking time of the combined group was (15.90±2.97)min, (31.47±4.42)min, respectively, which were both lower than those of the other two groups ( F value was 69.094, 114.549, P < 0.01). Conclusions:In endoscopic three-incision radical resection of esophageal cancer, combined heating makes the patients' temperature rise rapidly to offset the loss of heat, which is conducive to maintain a stable temperature. At the same time, the incidence of intraoperative hypothermia, postoperative chills and agitation is reduced, the temperature comfort of patients is improved, the extubation time and waking time are shortened, which is conducive to promote postoperative recovery of patients, thus reduce postoperative hypothermia related complications.

Objectives:To compare the efficiacy of retro-auricular single-site endoscopic thyroidectomy (RASSET) and that of transoral endoscopic thyroidectomy vestibular approach (TOETVA).Methods:In Department of Head and Neck Surgery, Sun Yat-sen University Cancer Center, 10 patients underwent RASSET from June 2021 to August 2021, and 21 patients underwent TOETVA from January 2016 to August 2021. All the 21 patients′ clinical data was analyzed retrospectively. There were 2 males and 8 females in the RASSET group, aging (48.2±13.9) years (range: 28 to 67 years). There were 5 males and 16 females in the TOETVA group, aging (31.3±8.2) years (range: 21 to 49 years). All patients underwent thyroid lobectomy. A 3 cm in length incision was cut on single auricula posterior sulci to creat the approach in the RASSET group. Then a Trocar made with of a glove was inserted. Retaining the omohyoid, the sternocleidomastoid muscle and anterior cervical muscle were pulled apart, exposing a single lobe of the thyroid gland and lymphatic tissue of zone Ⅵ, for en-bloc resection. The clinical data of the two groups were collected and analyzed by t test, Mann-Whitney U test, Fisher exact test or χ 2 test. Clinical data and postoperative efficacy indexes such as operation time, postoperative C reactive protein level, and postoperative complications were recorded. Results:Compared with the TOETVA group, the operation time was longer in the RASSET group ((256.8±77.0) minutes vs. (201.2±54.9) minutes, t=2.31, P=0.028), and increase of postoperative C reaction protein (24 hours postoperative vs. preoperative) was lower in the RASSET group (8.58(13.24) mg/L vs. 46.24(48.88) mg/L, Z=-4.311, P<0.01). But there was no significant difference between the RASSET group and TOETVA group in the number of lymph nodes dissection (2(5) vs. 2(3), Z=-0.326, P=0.759). Besides, there were no complications in the RASSET group. Conclusion:Retro-auricular single-site endoscopic thyroid loectomy is easy to achieve the en-bloc resection of tumors with a well-concealed scar and less traumatic dissection.
