AI Article Synopsis
- The study aimed to evaluate how different preoperative fasting times affect the safety and postoperative complications in patients undergoing painless gastrointestinal endoscopy for polyps.
- Patients were divided into an observation group with shorter fasting times (solid food for 6 hours and liquids for 2 hours) and a control group with traditional longer fasting times (solid food for 8-12 hours and liquids for 4 hours).
- Results indicated that the observation group had better blood glucose and electrolyte stability, less hunger and thirst, and lower incidences of nausea and vomiting compared to the control group, suggesting shorter fasting times are beneficial.
Article Abstract
Objective: To determine the effect of different preoperative fasting time on safety and postoperative complications of painless gastrointestinal endoscopy for polyps in patients.
Methods: Enrolled patients were assigned to an observation group and a control group by the random number table method (each n=68). Before operation, each patient in the observation group was fasted from solids for 6 h and from liquids for 2 h, while each one in the control group was fasted from solids for 8-12 h and from liquids for 4 h according to the conventional method. The levels of blood glucose, insulin, potassium and sodium in patients before and after operation were determined, and their hunger and thirst were recorded before anesthesia. Additionally, the incidences and degrees of vomiting and nausea among the patients after anesthesia and operation were recorded.
Results: Before operation, the observation group showed higher levels of blood glucose, insulin, serum potassium and serum sodium than the control group (all P<0.001), while after operation, the observation group showed lower levels of blood glucose and insulin and higher levels of serum potassium and serum sodium than the control group (all P<0.001). In addition, the degrees and incidences of hunger and thirst in patients of the observation group were significantly lower than those in the control group before operation (P<0.01), and the degrees and incidences of nausea and vomiting in the observation group were also notably lower than those in the control group before and after operation (both P<0.05).
Conclusion: For patients undergoing painless gastrointestinal endoscopy for polyps, shortening their fasting time from solids and liquids before operation can stabilize their blood glucose, insulin and electrolyte levels before and after operation, relieve their thirst and hunger before operation, and reduce the incidences of postoperative nausea and vomiting.

Background: Thyroid nodules classified cytologically as low-risk indeterminate lesions (TIR3A) on fine-needle aspiration biopsy (FNAB) present a clinical challenge due to their uncertain malignancy risk. This single-center study aimed to evaluate the natural history of TIR3A nodules.
Materials And Methods: FNABs performed between July 2017 and December 2019 were retrospectively retrieved and patients with TIR3A nodules were evaluated at baseline and throughout a follow-up based on ultrasound (US) parameters and clinical data.
