NEW to SurgeryU:
Ovarian Tissue Cryopreservation How to With Minimal Electrocautery
by Drs. Jessica R. Long, Jacqueline Y. Maher, and Veronica Gomez-Lobo
This NEW to SurgeryU video demonstrates a minimally invasive surgical technique used to perform a laparoscopic oophorectomy for the purposes of fertility preservation via ovarian tissue cryopreservation in a prepubertal individual. As the use of oophorectomy for fertility preservation increases, this video provides an example of a way to remove the ovary with minimal energy use, which in turn decreases thermal damage to the ovarian tissue. It also highlights the advancements in the nomenclature related to the ovarian regions and orientation.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach
This article provides an excellent review on diagnosis and management of endometriosis in the adolescent which is often a delayed diagnosis leading to decreased quality of life.
Journal of Minimally Invasive Gynecology, Volume 30, Issue 8, p616-626, August 2023, DOI: https://doi.org/10.1016/j.jmig.2023.03.017.
Emerging and Existing Ablative Surgical Technology for Adolescent Endometriosis Treatment
A new article in the Green Journal highlights the nuances of managing endometriosis in adolescents and key differences from adult women (1). Adolescents may already have signs of endometriosis around menarche. Upon laparoscopic evaluation, nearly 60-70% with dysmenorrhea may have early endometriosis (2-4). Symptoms like heavy menstrual bleeding and non-cyclic pelvic pain, which occurs in 90% of adolescents with endometriosis, may be overlooked (1). Over half have associated gastrointestinal and/or urinary symptoms or a comorbid pain syndrome (6-7).
A thorough history and abdominal exam remain the cornerstone of diagnosis. Ultrasound or MRI may aid in identifying adnexal pathology or reproductive tract anomalies that may suggest concurrent endometriosis (8). Consistent with established ACOG guidelines, a trial of hormonal therapy for 3-6 months should be considered, but laparoscopic evaluation thereafter for refractory symptoms is warranted (9).
On laparoscopic evaluation, adolescents often present with early lesions such as clear vesicles, white implants or petechiae, as opposed to the typical advanced endometriotic lesions found in adults. The few that present with advanced-stage endometriosis may more commonly present with endometriomas over extensive peritoneal disease (10). As such, Shim et al advocate for a more judicious approach to the surgical treatment of endometriosis in adolescents, avoiding the radical resection strategies used more commonly in adults (10). In these cases, ablation strategies can be a helpful alternative with many therapeutic benefits.
Electrosurgery and lasers specifically have an important role in ablation of early endometriosis lesions. Widely available and familiar to endoscopists, monopolar electrocautery set at a low level of 8 Watts provides therapeutic benefit without significant risk of damage to underlying organs (11). In conjunction with monopolar electrosurgery, the argon plasma coagulator can provide superficial fulguration and coagulation of lesions; however, its use is limited in a setting with high intra-abdominal insufflation pressure. Alternatively, the CO2 laser is inexpensive and can be used to vaporize or excise lesions with minimal risk to nearby structures. Other, more expensive lasers that mainly have a tissue coagulation effect are the Nd:YAG, KTP, and holmium lasers, which can take advantage of flexible fibers for increased ergonomics (12).
A new, compact laser diode unit called the TruBlue laser, by A.R.C. Laser Company in Nuremburg, Germany, uses blue light (445 nm wavelength) (Figures 1 & 2). Due to its high absorption in hemoglobin and negligible absorption in water, the TruBlue laser is reported to have improved coagulation capabilities compared to the KTP laser with a low rate of thermal spread (Figure 3) (13). It can deliver up to 4 Watts in a continuous wave or 10 Watts in a pulse wave output. It has a wide beam divergence; therefore, it is important to position close to the tissue for ablative effect to be achieved.

Studies comparing outcomes after ablation versus resection of endometriosis are sparse in adolescents, though radical resection has shown some negative consequences due to extensive adhesive disease post operatively (14). Nonetheless, surgeons have several options for delivering ablative therapy as a safe, alternative approach for endometriosis treatment in adolescents. Early recognition and treatment of adolescent endometriosis allows for minimization of chronic pelvic pain and optimization of their future fertility and quality of life.

Use of Interventional Radiology and Wire Localization for Septum Resection in a 13-Year-Old Patient With a High OHVIRA
Review:
Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) typically manifests as a didelphys uterus with an oblique vaginal septum on the same side as the renal anomaly and often presents around the time of menarche. The oblique septum obstructs menstrual egress from one cervix, leading to hematocolpos and distension of the obstructed hemivagina; thus, treatment of OHVIRA requires resection of the vaginal septum. Septal microperforations can make surgical treatment challenging as the obstructed hemivagina is decompressed, proximal, and difficult to identify. (Image 1)
Image 1: Drawing depicting high/proximal obstruction (left) versus low/distal obstruction (right) in OHVIRA.
Case Presentation:
A 13-year-old female with a known absent right kidney presented three years after menarche with dysmenorrhea and irregular menses. Ultrasound and subsequent MRI demonstrated a didelphys uterus, longitudinal/oblique septum, and a minimally dilated obstructed right hemivagina consistent with OHVIRA. (Image 2)
Image 2: MRI demonstrating two visible cervices (red arrows) with small hematocolpos (yellow arrow).
Exam under anesthesia and vaginoscopy demonstrated a single visible cervix slightly deviated to the left. Intraoperative ultrasound delineated the right hemiuterus and cervix; however, no hematocolpos, distended hemivagina, or microperforations were identified.
Given the inability to identify the exact location of the obstructed hemivagina, resection in typical manner was deferred. She was started on menstrual suppression with norethindrone acetate 5mg orally daily. Interval drainage using interventional radiology was performed with wire localization for septum resection. This was done with the patient in a frog-legged position and a transvaginal ultrasound probe with a needle guide with concurrent cone beam CT guidance fluoroscopy. The transvaginal ultrasound revealed a minimal fluid collection noted in this location which was cannulated with an 18-gauge Chiba needle (Image 3).
Image 3: Transvaginal needle used for injection of obstructed hemivagina with concurrent direct visualization with transabdominal ultrasound. Tip of needle noted (yellow arrow).
Contrast injection under fluoroscopy and cone beam CT guidance confirmed the position of the catheter within the vaginal collection immediately proximal to the membrane (Image 4).
Image 4: CT view of catheter placement into the distended hemivagina after injection of contrast.
The contrast injection also served to distend the obstructed hemivagina. This needle was then exchanged over Amplatz wire for a 6 French Dawson Mueller pigtail drainage catheter which was left in place and clamped. The patient was then transferred to the operating room, where she was placed in lithotomy position, and the insertion site of the catheter was visualized using vaginal wall retractors. No other microperforation was visualized at this time. Using the catheter as a guide (Image 5), stay sutures were placed on either side of the drain and the septum was incised using electrocautery over the drain, revealing a mix of old, brown blood and injected contrast.
Image 5: View of catheter traversing the obstructive vaginal septum with lateral stay sutures prior to surgical incision.
The majority of the remaining septum was excised using Bovie electrocautery, taking care to avoid injury to the cervices and surrounding structures. The vaginal epithelium was oversewn using 3-0 Vicryl sutures to approximate the tissue, and speculum exam confirmed visualization of both cervices.
Ten weeks later, the patient was taken to the operating room for an exam under anesthesia and vaginoscopy, which demonstrated bilateral visible cervices and minimal remaining septum. Image 6 demonstrates the proximity of the level of the septum to the cervix.

Conclusion:
The resection and repair of OHVIRA can be challenging when the level of obstruction is high with lack of distention to delineate the obstructed hemivagina. Concurrent use of fluoroscopy and ultrasonographic guidance can allow for definitive confirmation of the space and provide a helpful guide for safe repair.
