This educational lecture provides a comprehensive overview of Laparoscopic Uterine Manipulators, focusing on their classification, clinical indications, and a detailed step-by-step operative technique. Ideal for gynecologists, laparoscopic surgeons, and trainees seeking a clear and practical understanding of uterine manipulation during minimally invasive surgery.

Laparoscopic uterine manipulators are essential instruments in modern minimally invasive gynecologic surgery. They play a crucial role in providing uterine mobility, improving visualization, and facilitating safe dissection during various laparoscopic procedures. Proper understanding of their types, indications, and correct technique is vital to maximize surgical efficiency while minimizing complications.

Types of Laparoscopic Uterine Manipulators
Uterine manipulators are broadly classified into simple and advanced systems. Simple manipulators include sponge stick holders and basic uterine sounds, which offer limited mobility and are mainly used in diagnostic laparoscopy. Advanced manipulators, such as the VCare®, RUMI®, Clermont-Ferrand, and Hohl uterine manipulators, allow multi-directional movement, uterine elevation, and delineation of vaginal fornices. Some devices include colpotomy cups and balloon systems that enhance safety during total laparoscopic hysterectomy (TLH) by clearly defining the cervicovaginal junction.

Indications for Use
Laparoscopic uterine manipulators are indicated in a wide range of gynecologic surgeries, including laparoscopic hysterectomy, myomectomy, endometriosis surgery, and adnexal procedures. They help in anteversion, retroversion, lateral movement, and elevation of the uterus, thereby exposing surgical planes and reducing the risk of injury to adjacent organs such as the ureters, bladder, and bowel.

Correct Technique of Use
Correct placement of the uterine manipulator begins with proper patient positioning in the lithotomy position under anesthesia. After cervical dilation, the appropriate size of the manipulator is selected to avoid uterine perforation. The device is gently inserted into the uterine cavity and secured according to the manufacturer’s instructions. During surgery, coordinated communication between the surgeon and assistant is essential to apply controlled movements without excessive force.

Step-by-Step Surgical Guide

Position the patient in dorsal lithotomy and perform antiseptic preparation.

Grasp the cervix with a tenaculum and measure uterine depth using a uterine sound.

Select the correct manipulator size and assemble it properly.

Insert the manipulator gently into the uterine cavity and secure it.

Adjust the colpotomy cup or vaginal delineator if required.

Use controlled uterine movements to facilitate dissection during laparoscopy.

Remove the manipulator carefully at the end of the procedure.

Conclusion
Laparoscopic uterine manipulators significantly enhance surgical precision and safety in minimally invasive gynecologic surgery. Knowledge of different types, proper indications, and correct step-by-step usage ensures optimal outcomes and reduces intraoperative complications. Mastery of these instruments is therefore an essential skill for every laparoscopic gynecologic surgeon.
