Mimics and Pitfalls of Primary Ovarian Malignancy Imaging

The complex anatomy and similarity of imaging features of various pathologies in the pelvis can make accurate radiology interpretation difficult. While prompt recognition of ovarian cancer remains essential, awareness of processes that mimic ovarian tumors can avoid potential misdiagnosis and unnecessary surgery. This article details the female pelvic anatomy and highlights relevant imaging features that mimic extra-ovarian tumors, to help the radiologists accurately build a differential diagnosis of a lesion occupying the adnexa.

A Novel Use of Laryngoscope for Difficult Papanicolaou Smear Collection

The prevalence of cervical cancer has dropped significantly since introduction of the Papanicolaou (Pap) screen. The greatest risk factor for cervical cancer is inadequate screening. Altered pelvic anatomy can limit the ability to collect a Pap smear. In the presented case, a woman with a history of fibroids and bleeding presented for an exam under anesthesia. Traditional approaches for collecting a Pap smear failed. A GlideScope video laryngoscope was used to visualize the cervix, and a Pap smear was collected. The specimen was satisfactory, negative for intraepithelial lesion or malignancy, and HPV negative. A laryngoscope can be repurposed to visualize collection of a challenging Pap smear. Novel approaches for Pap smear collection and cervical cancer screening are needed and have the potential to save lives.

Pelvic Anatomy for Distal Rectal Cancer Surgery

Worldwide, colorectal cancer is the third most common cancer and one of the leading causes of cancer-related deaths. Currently, total mesorectal excision (TME) is considered as the gold standard surgical procedure for rectal cancer. To achieve a good oncologic outcome and functional outcome after TME in distal rectal cancer, exact knowledge regarding the pelvic anatomy including pelvic fascia, pelvic floor, and the autonomic nerve is essential. Accurate TME along the embryologic plane not only reduces local recurrence rate but also preserves urinary and sexual function by minimizing nerve damage. In the past, pelvic floor muscles and autonomic nerves could not be visualized clearly, however, the development of imaging studies and improvements of minimally invasive surgical techniques such as laparoscopic and robotic surgery can clearly show the anatomy of the pelvic region. In this chapter, we will provide accurate anatomy of the rectum and the anal canal, pelvic fascia, and the pelvic autonomic nerve. This anatomical information will be an important indicator for performing an adequate operation for distal rectal cancer.

O-058 The impact of endometriosis on fertility treatment

Abstract text Endometriosis can affect natural fertility by distorting pelvic anatomy and by causing local pelvic inflammation that affects the quality of the oocytes, the function of the tubes and the sperm capacity to fertilize. Two approaches can be foreseen, either removing the disease with the aim of restoring normality (surgery) or overcoming the disease by retrieving oocytes in the ovary and allowing their fertilization in in vitro conditions (IVF). Both therapeutic approaches seem rational and wise. However, despite this apparently simple clinical scenario, management of endometriosis-related infertility has engendered long-lasting and burning debates over the last two decades and, to date, no consensus has been reached. Robust scientific evidence is scant, actually limited to the demonstration that laparoscopy modestly increases the chance of natural conception. In this debate, it is noteworthy that chances of pregnancy do not represent the unique stake. Other factors can play a role and deserves consideration. Considering the choice of fertility treatment, he most relevant are the following: 1) the impact of ovarian endometriomas and their removal on ovarian responsiveness, 2) the impact of endometriomas and endometriosis in general on oocytes quality, 3) the additional risks of oocytes retrieval in the presence of endometriosis (infections in particular) 4) the detrimental effects of endometriosis-related hydrosalpinx, 5) the impact of endometriosis on uterine motility and endometrial receptivity, 5) the confounding effect of endometriosis-associated adenomyosis. Unfortunately, for the vast majority of these concerns, evidence is not definite and physicians have to take decisions based on their clinical commonsense.

The “virtual OR:” creation of a surgical video-based gynaecologic surgery teaching session to improve medical student orientation and supplement surgical learning during COVID-19

Implication Statement The COVID-19 pandemic resulted in changes to clinical clerkship delivery including decreased surgical exposure. The Department of Obstetrics and Gynaecology at Dalhousie University developed a novel, resident-led learning experience using a curated presentation of operative footage. This session aimed to improve medical students’ orientation to the operative environment and supplement teaching on pelvic anatomy and gynaecologic surgery in response to decreased exposure during the COVID-19 pandemic. Medical students perceived this session as valuable and felt it improved their preparedness for the operating room. This initiative has the potential to improve medical student orientation to the operative environment.

Pelvic Lymphadenectomy in Gynecologic Oncology—Significance of Anatomical Variations

Pelvic lymphadenectomy is a common surgical procedure in gynecologic oncology. Pelvic lymph node dissection is performed for all types of gynecological malignancies to evaluate the extent of a disease and facilitate further treatment planning. Most studies examine the lymphatic spread, the prognostic, and therapeutic significance of the lymph nodes. However, there are very few studies describing the possible surgical approaches and the anatomical variations. Moreover, a correlation between anatomical variations and lymphadenectomy in the pelvic region has never been discussed in medical literature. The present article aims to expand the limited knowledge of the anatomical variations in the pelvis. Anatomical variations of the ureters, pelvic vessels, and nerves and their significance to pelvic lymphadenectomy are summarized, explained, and illustrated. Surgeons should be familiar with pelvic anatomy and its variations to safely perform a pelvic lymphadenectomy. Learning the proper lymphadenectomy technique relating to anatomical landmarks and variations may decrease morbidity and mortality. Furthermore, accurate description and analysis of the majority of pelvic anatomical variations may impact not only gynecological surgery, but also spinal surgery, urology, and orthopedics.
