Objective: To investigate the effects of ultrasoundguided realtime precise caudal block combined with laryngeal mask airway (LMA) general anesthesia on intraoperative stress response and postoperative bowel function recovery in patients undergoing vaginal hysterectomy. Methods: This prospective, singlecenter randomized controlled trial enrolled 108 patients who underwent elective vaginal hysterectomy in our hospital from January 2023 to January 2025. They were randomly divided into a control group (n=54) and an observation group (n=54). The control group received LMA general anesthesia alone, while the observation group received ultrasoundguided realtime precise caudal block (0.25% ropivacaine 20 mL) combined with LMA general anesthesia. The following parameters were compared between the two groups: hemodynamic variables [mean arterial pressure (MAP), heart rate (HR)] at different intraoperative time points, stress response indicators [serum cortisol (COR), norepinephrine (NE), blood glucose (GLU)], postoperative bowel function recovery indicators (time to bowel sound recovery, time to first defecation, time to first flatus), postoperative pain Visual Analog Scale (VAS) scores, effective pressing times of patientcontrolled analgesia (PCA) pump, rescue analgesia rate, and incidence of adverse reactions. The primary outcome was the 24 h postoperative VAS score; secondary outcomes included intraoperative stress response indicators and postoperative bowel function recovery indicators. Results: No significant differences were found between the two groups in age, BMI, operative time, or intraoperative blood loss (P>0.05). Compared with T0, MAP and HR at T1, T2 and T3 were increased in both groups, but the MAP and HR at T1, T2 and T3 in the observation group were significantly lower than those in the control group (P<0.05). Levels of COR, NE and GLU at T1, T2 and T3 were higher than those at T0 in both groups, but the levels in the observation group were significantly lower than those in the control group at the corresponding time points (P<0.05). The time to bowel sound recovery, time to first defecation and time to first flatus in the observation group were significantly shorter than those in the control group (P<0.05). The VAS scores at 2 h, 6 h, 12 h and 24 h postoperatively in the observation group were significantly lower than those in the control group (P<0.05); the effective pressing times of PCA pump and the rescue analgesia rate in the observation group were also significantly lower than those in the control group (P<0.05). The incidence of postoperative nausea and vomiting (PONV) in the observation group was significantly lower than that in the control group (P<0.05), whereas no significant difference was observed in the incidence of urinary retention between the two groups (P>0.05). Conclusion: Ultrasoundguided realtime precise caudal block combined with LMA general anesthesia can effectively alleviate intraoperative stress response, maintain hemodynamic stability, promote postoperative bowel function recovery, and improve postoperative analgesia quality in patients undergoing vaginal hysterectomy, without increasing the incidence of adverse reactions. Therefore, this combined anesthesia technique is worthy of clinical application.

[Abstract]Objective:To explore the application effect and safety of ultrasound bone scalpel and high-speed turbine mobile phone in surgical procedures for patients with jaw cysts.Methods:A total of 100 patients with maxillary cysts who underwent curettage surgery in our hospital from January 2024 to June 2025 were selected for the study. The enrolled patients were randomly divided into a control group and an experimental group using the hidden envelope method, with 50 patients in each group. The conventional group used high-speed turbine mobile phones for bone removal during surgery, while the experimental group used ultrasonic bone knives for bone removal during surgery. The surgical conditions, postoperative pain and swelling, and incidence of complications during hospitalization were compared between the two groups of patients. Follow up for six months after surgery to compare the nerve damage and bone healing between the two groups of patients.Results:The intraoperative bleeding volume, postoperative 24-hour drainage volume, and bone cutting accuracy deviation of the experimental group were (30.59 ± 5.24) mL, (20.55 ± 5.28) mL, and (0.18 ± 0.05) mm, respectively, all lower than those of the control group [(40.19 ± 7.33) mL, (30.46 ± 6.45) mL, and (0.59 ± 0.12) mm] (t=7.534，8.407，22.301; P<0.05); The surgical time of the experimental group was similar to the control group (P>0.05). The VAS scores and swelling scores of the experimental group at 24, 48, and 72 hours after surgery were lower than the control group (t=4.403，3.354，12.986，4.610，2.911，14.888；; P<0.05). The incidence of complications during hospitalization in the experimental group was 4.00% (2/50) lower than the control group 18.00% (9/50) (x2=5.005; P<0.05).The NCV of the experimental group was higher than the control group at the1,3,6 months of follow-up, and TPD was lower than the control group (t=4.598，5.784，6.322，3.194，3.595，3.501; P<0.05). As of the end of follow-up, the osteogenic rate of the experimental group was (75.27 ± 8.14)% higher than the control group (68.18 ± 5.27)%. The bone defect area, wound healing time, and bone resorption were (55.29 ± 5.42)%, (3.22 ± 0.47) months, and (1.25 ± 0.36) mm, lower than the control group [(62.44 ± 7.51)%, (5.08 ± 1.33) months, and (2.49 ± 0.32) mm] (t=5.170，5.459，9.324，18.204; P<0.05).Conclusion:Compared with high-speed turbo phones, ultrasonic bone scalpel can reduce the risk of intraoperative bleeding in patients with jaw cysts and achieve precise bone removal. It can alleviate postoperative pain and swelling while greatly avoiding postoperative nerve damage, and has a positive impact on promoting bone healing in patients.

Using surgical pathology as the gold standard, the sensitivity, specificity, and accuracy of ultrasound and SPECT/CT were calculated at the regional level (216 regions in total), and the detection rates in different anatomical regions were compared.?Results?Among the 54 patients, 45 (83.33%) were confirmed with SHPT. The sensitivity, specificity, and accuracy of ultrasound were 70.89% (112/158), 86.21% (50/58), and 75.00% (162/216), respectively; while those of SPECT/CT were 92.41% (146/158), 94.83% (55/58), and 93.06% (201/216), respectively. The sensitivity and accuracy of SPECT/CT were significantly higher than those of ultrasound (both?P<0.001). The detection rates of SPECT/CT in the upper-left, lower-left, and upper-right regions were significantly higher than those of ultrasound (P<0.05).?Conclusion?99mTc-MIBI SPECT/CT dual-phase imaging demonstrates superior sensitivity and accuracy compared with cervical ultrasound in preoperative localization of SHPT, especially showing significant advantages in detecting lesions in the upper-left, lower-left, and upper-right regions. It can serve as an important supplement or the first-choice imaging modality for preoperative localization in SHPT patients.
