Objective To investigate the safety and efficacy of pseudomonas aeruginosa Injection(PAI)in the treatment of coeliac leakage after cervical lymph node dissection for robotic thyroid cancer.Methods Ret-rospective analysis of 1262 patients who underwent robotic thyroid surgery at the 960th Hospital of the People's Liberation Army from Jan.2021 to Aug.2023 was made.Postoperative celiac leakage happened in 28 patients.The control and injection groups were divided according to whether pseudomonas aeruginosa injection was used or not.In the control group,there were 4 males and 11 females out of 15 patients,with an average age of(46.20±9.02)years old,and the treatment methods of low-fat diet,negative pressure suction,and pressure bandage were used.In the injection group,there were 7 males and 6 females among 13 patients,with an average age of(41.00±8.87)years.They were treated with low-fat diet,negative pressure suction,pressure bandage,and PAI.The number of lymph node dissection,total drainage volume,peak drainage volume,days of hospitalization and the rate of decline in drainage volume within 24 h after the use of PAI in the injection group,post-injection temperature,number of in-jections,and post-injection extubation time were statistically analyzed in both groups.Independent samples t test,Mann-Whitney U test,x2 test or Fisher's exact test were used for comparison between groups.Results There was no statistically significant difference in age,gender,extent of thyroidectomy,highest daily drainage volume,and to-tal drainage volume between the two groups(P＞0.05).The difference in the number of lymph node dissection(49.15±23.05 vs.30.80±11.76,P=0.012)and hospitalization time(11.77±4.64 vs.16.40±6.42,P=0.041)between the injection group and the control group was statistically significant.After the use of pseudomonas aeruginosa in-jection,the draining fluid decreased from the previous day(69.56±20.82)％in the injection group;Twelve pa-tients were successfully extubated after one injection of pseudomonas aeruginosa injection,and one patient was suc-cessfully extubated after two injections;the mean time to extubation after injection was(3.85±1.28)days;76.9％pa-tients(10/13)had fever symptoms within 48 h with body temperature(38.05±0.89)℃ after injection,body tempera-ture returned to normal after symptomatic treatment,and no other adverse reactions occurred except fever.Conclu-sion Pseudomonas aeruginosa injection is safe and effective in the treatment of celiac leakage after cervical lymph node dissection for robotic thyroid cancer,effectively reducing cervical drainage and shortening hospitalization days.
