Objective To discuss the ultrasonographic characteristics of schistosomal appendicitis lesions. Methods Among the patients with schistosomal hepatopathy who were discovered by Color Doppler ultrasound in Huzhou Central Hospital from January 2012 to December 2015,50 cases with clear history of schistosomiasis and treatment were chosen as a schistosom?al hepatopathy group,meanwhile,50 normal people,who came from non?endemic areas,without schistosomal hepatopathy and schistosomiasis history were chosen as a control group. The two groups were examined by ultrasound scan of the appendix ,and the data of the largest diameter of the appendix and the thickness of the appendix wall were collected,and the sonographic char?acteristics of their appendixes,such as whether the echo of the appendix wall was even or not,were observed. Results The minimum internal diameter of the appendix cavity and the thickness of the appendix wall of the schistosomal hepatopathy group were(2.090 ± 0.790)mm and(1.332 ± 0.313)mm ,respectively,the former was significantly narrower than that of the control group,while the latter was significantly thicker than that of the control group(t=2.647,-4.526,respectively,both P<0.05). The proportions of those with inhomogeneous echo,indistinctness structure,uneven thickening of the appendix wall,as well as having intestinal contents in the appendix cavity in the schistosomal hepatopathy group were higher than those in the control group(χ2=12.000,18.537,24.008,4.244,respectively,all P<0.05). Conclusions Schistosomal appendicitis lesions have obvious ultrasonographic characteristics under ultrasound. Ultrasound can play an important role in judging whether the appen?dix of schistosomiasis patients is involved and discovering the lesion of appendix early.

Objective:To develop a simple, practical and repeatable ultrasound method to locate the muscle at the trigger point of female myofascial pelvic pain(MPP), which can provide imaging reference for clinical precision treatment.Methods:A total of 113 patients with suspected MPP who came to the Women′s Hospital School of Medicine Zhejiang University from September 1, 2021 to April 20, 2023 were prospectively selected. The gynecologist performed internal examination with index finger on some pelvic floor muscles (puborectalis, pubococcygeus, iliococcygeus, coccygeus) and pelvic wall muscles (piriformis and obturator internus) respectively, searched for the muscles where the pain trigger point was located, and scored the pain by referring to visual analogue scale (VAS) and numerical rating scale (NRS), and then referred the patients to the ultrasound department. The ultrasound doctor used transvaginal ultrasound to display the above muscle groups in real time for observation and appropriate pressure. The muscle where the painful trigger point was located was found through tenderness and the pain score was performed. The two scores were compared for consistency and difference analysis.Results:The trigger point was clear and of good reproducibility. For the location and score of pain trigger points located in bilateral puborectalis, pubococcygeus and coccygeus, there was a strong consistency between the tenderness guided by vaginal ultrasound probe and clinical palpation (the consistency rate was ≥70%), and there was no significant difference in the pain scores of the trigger points located in the puborectalis muscle and coccygeal muscle between the two methods ( P>0.05), and there was statistically significant difference in the pain scores of the trigger points located in the other pelvic floor and pelvic wall muscles (all P<0.05). At the same time, ultrasonic examination made up for the deficiency of clinical palpation in the evaluation of piriformis muscle. Conclusions:The present method for finding the trigger point of MPP guided by the ultrasound probe is a new non-invasive, safe, simple and practical imaging method, which can provide a new imaging reference for the clinical diagnosis of MPP and the formulation of treatment strategies.
