Abstract:
Objective:To analyze the clinical characteristics, treatment and prognosis of chyle leakage after central lymph node dissection for thyroid cancer.
Methods:A retrospective analysis was made of 985 patients who underwent surgical for thyroid carcinoma plus central lymph node dissection from January 2017 to June 2018 in Renji Hospital Affiliated to Medical College of Shanghai Jiaotong University. Patients were divided into those without (group A, n=973) and with (group B, n=12) chyle leakage. Patients with chyle leakage who underwent left central lymph node dissection were divided into group B1 (n=5) and right central lymph node dissection into group B2 (n=7). Patients with chyle leakage were treated with fat-free diet and negative pressure drainage. SPSS 20.0 software was used to analyze the general condition, surgical pathology, postoperative drainage, hospitalization days, treatment and prognosis of patients in B1 and B2 groups.
Results:The incidence of chyle leakage after central lymph node dissection for thyroid cancer was 1.2% (12/985). There were no significant differences in age, sex, size of primary lesion, number of lymph node dissection in central area and number of lymph node metastasis in central area between group A and group B (all P>0.05). The drainage volume on the first day after operation [((51.7±26.7)) ml] and the average hospitalization days [(3.4±0.8) d] in group A were significantly lower than those in group B ([131.3±56.0)]ml, [10.4±2.6)]d). The differences were statistically significant (t value was -5.442, -11.238, respectively, both P<0.001). There were no significant differences in age, size of primary lesion, number of lymph node dissection, number of lymph node metastasis, drainage volume on the first day after operation and average hospitalization days between group B1 and group B2 (all P>0.05). All chyle leakages in group B stopped after conservative management without surgical intervention.
Conclusion:The occurrence of chyle leakage after central lymph node dissection is a rare complication. It can be cured by conservative treatment such as diet control, pressure bandaging and negative pressure drainage, and generally does not require secondary surgery.
