In 2008, Querleu and Morrow proposed a novel classification of radical hysterectomy, which was quickly accepted by the professional oncogynecological community. The Querleu and Morrow (Q-M) classification of radical hysterectomy has provided a unique opportunity for uniform surgical and anatomical terminology. The classification offers detailed explanations of anatomical landmarks and resection margins for the three parametria of the uterus.

Radical hysterectomy is a central surgical procedure in gynecological oncology. A nerve-sparing approach is essential to minimize complications from iatrogenic injury to the pelvic nerves, resulting in postoperative urinary, anorectal, and sexual dysfunction. The hypogastric plexus (HP), a complex network of sympathetic and parasympathetic nerves, plays a critical role in pelvic autonomic innervation.

The aim of this study was to investigate the risk factors for lymph node metastasis (LNM) in patients with uterine serous cancer (USC) who underwent systematic staging surgery. Eighty patients who were operated on for pure uterine serous papillary carcinoma between 2008 and 2020 in our clinic were retrospectively analysed. The effects of demographic information and clinicohistopathological characteristics of the included patients on LNM were examined.

Lymphadenectomy has been an essential part of the surgical treatment in surgical oncology, as the lymphatic channels and nodes are the main dissemination pathway for most of the gynecological cancers. Pelvic and paraaortic lymphadenectomy are frequent surgical procedures in gynecologic oncology. Paraaortic lymph node dissection facilitates staging, prognosis, surgical and postoperative management of patients.

The surgical treatment of gynecological malignancies is, except for tumors diagnosed at the earliest stages and patients' desire for fertility preservation, not limited to only the affected organ. In cases of metastatic iliac lymph nodes, gynecological tumors or recurrences located near the pelvic sidewall, oncogynecologists should dissect tissues in that region. Moreover, surgery of deep infiltrating endometriosis, e.

Purpose: Borderline ovarian tumors (BOTs) constitute about a quarter of epithelial ovarian malignancies and require different treatment approaches. The present study aims to document the experience of a single center on the treatment outcome of women who had conservative or comprehensive surgery for BOTs.

Methods: One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013, were reviewed retrospectively.

Article Synopsis
  • Cold knife conization is a surgical procedure used to diagnose and treat high-grade cervical lesions (CIN), and this study focused on the outcomes of cases without CIN after undergoing the procedure for prior lesions.
  • A retrospective analysis was conducted on 173 women who had the conization, comparing those who had no CIN (Group 1) to those with residual CIN (Group 2) over one year post-surgery.
  • Results showed no significant differences in demographics, HPV status, or recurrence rates between the two groups, suggesting similar follow-up care for both types of cases post-conization.

Serous borderline ovarian tumors (SBOT) generally occur in young women, present at early stages and are associated with an excellent prognosis. However, there are rare subtypes of SBOT which may exhibit a more aggressive course. In contrast with other types of SBOT, the micropapillary variant SBOT (SBOT-MP) tends to present at advanced stages.

This study compared the effects of axial dynamization and staged destabilization on fracture healing. Bilateral midshafts of canine tibiae were osteotomized and fixed with an external fixator. The hind limbs were divided into two groups: the destabilized group in which the fixator's stiffness was progressively reduced over time and the axially dynamized group in which the fixator was axially dynamized.
