Epithelial Ovarian Cancer (EOA) is a malignancy with poor
prognosis. Some findings indicate that the fallopian tubes may play a central
role in its pathogenesis. Therefore, it has been suggested that bilateral
prophylactic salpingectomy at the time of hysterectomy for benign condition
would reduce the risk of developing EOA. Nowadays, more and more surgeons use
robotic assistance to perform laparoscopic hysterectomy. The number and size of
trocars may influence postoperative pain. We present in a video a standardized Robotically
Assisted Laparoscopic Salpingectomy (RALS) using only two instruments and
trocars.

2. Introduction and
Aim of the Video
Ovarian cancer is a major cause
of cancer death among women and has the highest mortality rate of all types of
gynecologic cancer [1]. Attempts of screening have not been successful so far.
The majority of ovarian malignancies are derived from epithelial cells. Some
experts have suggested that Epithelial Ovarian Carcinoma (EOC) is derived from
the fallopian tube and the endometrium, and is not directly from the ovary [2].
Therefore, it has been suggested that bilateral salpingectomy at the time of
hysterectomy performed for benign disease may reduce the risk of EOC [3]. In
order to conserve ovarian function, opportunistic salpingectomy has to be
performed without impairing ovarian vascularization. Many gynecologists
nowadays perform Robotically Assisted Laparoscopic Hysterectomy (RALH). Robotic
assistance with three-dimension vision may help surgeons better visualize
vessels and reduce blood loss. Results from randomized controlled studies show
similar results to standard laparoscopic hysterectomy, but at the price of
higher costs [4,5]. Postoperative pain varies among studies [6]. We believe
that pain is not linked to the technique (standard laparoscopy or robotically
assisted laparoscopy), but to the number and size of trocars used during the
procedure along with the length of surgery. Therefore, use of the smallest
trocars and reduction in their number is of importance. We showed in a previous
study that RALH could be easily performed with three trocars only [7]. We
present in a video a standardized technique of robotically assisted
laparoscopic prophylactic salpingectomy using only two standard instruments introduced
by two trocars.
3. Case Report
Our video shows the case of a
prophylactic bilateral salpingectomy performed during hysterectomy with High
Uterosacral Ligament Suspension (HULS) in a 51 years old woman, gravida 3 para
1, with no significant comorbidity. Three years before, she had robotically
assisted laparoscopic repair of anterior vaginal wall and uterine prolapse by
lateral suspension with mesh for Pelvic Organ Prolapse (POP) stage 3. At that
time, she wanted to preserve potential fertility and refused opportunistic
salpingectomy. She subsequently developed abnormal uterine bleeding and
myomatous uterus, with two intramural 2 cm large myomas at pelvic sonography.
She was also complaining of vaginal discomfort with sensation of POP
recurrence. The indication for hysterectomy was symptomatic myomatous uterus,
and symptomatic elongation (5 cm) and hypertrophy of the cervix reaching the
hymen. She finally accepted salpingectomy.
4. Results
The
patient was placed in the lithotomy position under general anesthesia. We set
up a HOHL manipulator (Karl Storz Company Tuttlingen Germany) at the beginning
of the procedure to expose the uterus. We administered antibiotic prophylaxis
(Cefazolin 2g IV (Kefzol®)) at anesthetic induction. We performed
insufflations of CO2 with a Veress needle introduced at Palmer point
(left hypochondrium). We placed three 8 mm trocars (an 8 mm umbilical port for
a 0° optique and two 8 mm lateral ports for the instruments) and used
the Da Vinci Xi robot (Intuitive Surgical, Sunnyvale California USA). The video
illustrates bilateral RALS during hysterectomy using monopolar scissors and a
bipolar grasper. Salpingectomy starts with fenestration of the mesosalpinx
using monopolar scissors. The scissors introduced in this window allow lifting
and exposure of the tube to perform bipolar coagulation of the mesosalpinx
along the tube in both directions. Three-dimension robotic vision makes it
possible to coagulate the vessels selectively and to best preserve ovarian
vascularization. Monopolar scissors are used to cut, but also to coagulate
tissue along the tube. It is important to remove the entire tube especially the
fimbria ovarica. Both tubes remain attached proximally to the uterus and are
removed with it by the vagina at the end of the procedure.
5. Conclusion
We
believe our video may help surgeons perform salpingectomy in a standardized way
during RALH without the need of an additional assistant trocar.
