Objective To evaluate postoperative recovery and health-related quality of life in patients undergoing robotic,laparoscopic,or open total hysterectomy.Methods A total of 152 patients who underwent total hysterectomy at the Department of Obstetrics and Gynecology of The Second Affiliated Hospital of Naval Medical University from May 2022 to May 2024 were enrolled and assigned to robot-assisted laparoscopic surgery group(robotic surgery group,44 cases),traditional laparoscopic surgery group(laparoscopic surgery group,62 cases),or open surgery group(46 cases)based on the surgical approach.General information,perioperative indexes,and discomfort symptoms 1 month after discharge were collected.Health-related quality of life was evaluated using 36-item short-form health survey(SF-36)at 1-month postoperative follow-up.Results There were no significant differences in age,body mass index,education level,work status,or diagnosis of benign or malignant diseases(all P＞0.05).The postoperative hospital stay,time of first ambulation,time of first oral intake,and 24-h pain score in the robotic surgery group were significantly lower than those in the laparoscopic and open surgery groups(all P＜0.01).The incidence of urinary system and digestive system discomfort within 1 month after discharge was significantly lower in the robotic surgery group than in the laparoscopic and open surgery groups,and the incidence of lower abdominal pain was significantly lower in the robotic surgery group than in the open surgery group(all P＜0.01).The scores of SF-36 in each dimension were significantly higher in the robotic surgery group than those in the laparoscopic and open surgery groups 1 month after discharge(all P＜0.01).Conclusion Compared with those undergoing traditional laparoscopic or open total hysterectomy,patients who underwent robot-assisted laparoscopic total hysterectomy demonstrate faster postoperative recovery and better health-related quality of life.

Objective To explore the imaging characteristics and diagnostic value of 18 F-FDG PET/CT in patients with hepatic epithelioid hemangioendothelioma ( HEH) . Methods From January 2014 to December 2015, 5 HEH patients (2 males, 3 females; average age (49.2±13.7) years) confirmed by pathology and underwent 18 F-FDG PET/CT imaging were enrolled in this retrospective study. The character-istics of PET/CT images were analyzed. Two-sample t test and Pearson linear correlation analysis were used for data analysis. Results A total of 26 lesions were detected in 4 patients with multiple lesions, of which 88.5%( 23/26) distributed at the liver edge, and 42. 3%( 11/26) had hepatic capsule retraction sign. SUVmax of the 26 lesions was 5.1±2.6 and it was not correlated with tumor size (r=0.054, P>0.05). Lesion FDG uptake in patients with distant metastases was higher than that in patients without distant metastases (6.08±1.80 vs 3.84±1.14;t=4.15, P<0.05). Two patients underwent the delayed imaging, and FDG up-take in 11/14 lesions was higher compared with that of early imaging, and 3/14 lesions were newly detected by the delayed imaging. One patient had diffuse low-density lesions with diameters between 6.1 and 35.5 mm and SUVmax between 2.6 and 8.1. Conclusion Liver lesions of HEH patients show some features on 18F-FDG PET/CT images which can find distant metastases, and the delayed imaging can improve the detection rate of lesions.
