Key result
Laparoscopic cholecystectomy is linked to postoperative low-T3 syndrome with significant TT3 drops and rT3 increases.
Why the study?
The impact of mild surgical stress from different surgical procedures on thyroid hormone metabolism remains to be elucidated.
Does laparoscopic cholecystectomy induce changes in thyroid hormone metabolism?
Comparison
Thyroid hormone levels before, during, and after laparoscopic cholecystectomy
Design
Observational cohort study
Follow-up
24 hours postoperatively

Low-T3 syndrome develops even with mild laparoscopic stress; leaves open whether perioperative thyroid monitoring should inform management in low-risk patients.

Does laparoscopic cholecystectomy induce changes in thyroid hormone metabolism?
p-value: p=<0.05
Laparoscopic cholecystectomy induces a low-T3 syndrome characterized by decreased TT3 and increased rT3 levels.
Legakis et al. (1998) conducted an observational in Patients undergoing laparoscopic cholecystectomy (n=22). Laparoscopic cholecystectomy vs. Baseline (preoperative) was evaluated on Changes in TT4, TT3, rT3 and TSH levels (p=<0.05). Laparoscopic cholecystectomy induced a low-T3 syndrome, with decreased TT3 levels and a significant increase in rT3 at 24 hours postoperatively (p<0.05).
