Objective:
To evaluate the application value of laparoscopic ultrasonography (LUS) in gynecological surgery.
Methods:
Retrospective analyses were performed for 52 cases undergoing LUS during laparoscopic extirpation/excision of gynecological tumors. Aloka 7.5-MHz laparoscopic probe was used to detect the residual lesions during laparoscopic operations. The findings of LUS were compared with those of preoperative transvaginal ultrasound and postoperative pathohistological examinations.
Results:
Preoperative diagnoses were corrected by LUS in 9 cases. And 34 residual lesions located by LUS were successfully removed.
Conclusion:
With a high detection rate and diagnostic accuracy rate in the diagnosis of gynecologic disease, LUS can locate invisible lesions during laparoscopic operations and provide guidance for radical tumor removal. It is a safe and valuable assistance for gynecologic surgery.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
