Article Synopsis
  • The study aims to assess the practice of robotic sentinel lymph node dissection in endometrial cancer surgeries, especially for advanced cases limited to the uterus.
  • The analysis involved 93 patients who underwent this procedure from January 2018 to January 2024, using indocyanine green, revealing a high sensitivity (96.32%) and specificity (100%) in detecting sentinel lymph nodes.
  • The results of this practice align well with existing literature, indicating its effectiveness in both low-risk and high-risk endometrial cancer patients.

Objective: Endometriosis is a disease in which stromal cells and endometrial glands extend outside of the uterine cavity. Nevertheless, treatment failure and recurrence cause difficulties in management. This study aimed to evaluate the receptor-level components of bilateral endometriomas in the recurrence state.

Aims: Sentinel lymph node dissection is performed in endometrial cancer surgery instead of staging surgery, particularly when the disease is advanced and confined to the uterus. The aim of this study is to share our sentinel lymph node detection rates via the vaginal natural orifice transluminal endoscopic surgery method with the literature and to demonstrate a safer and more comfortable surgical treatment process.

Methods: The analysis includes the patients who underwent surgery sentinel lymph node dissection for endometrial cancer utilizing indociyanin green in our center between January 2022 and June 2024.

Article Synopsis
  • The study aims to identify biomarkers that predict the progression of COVID-19 in pregnant women, particularly focusing on blood parameters and inflammatory markers.
  • The research involved a case-control group of pregnant women with COVID-19 and a matching group without the virus, analyzing factors like platelet-to-lymphocyte ratio and C-reactive protein levels.
  • Findings indicated that the patient group had significantly higher platelet-to-neutrophil ratios, platelet-to-lymphocyte ratios, and C-reactive protein levels compared to the control group, suggesting these could be important indicators of disease severity.

Background: There is an ongoing search for standardized scales appropriate for each culture to evaluate professionalism, which is one of the basic competencies of a physician. The Professionalism Mini-evaluation Exercise (P-MEX) instrument was originally developed in Canada to meet this need. In this study, it was aimed to adapt the P-MEX to Turkish and to evaluate the validity and reliability of the Turkish version.

Aim: This study aimed to compare the surgical outcomes of total laparoscopic hysterectomy (TLH) and vaginally assisted natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy procedures in obese patients.

Materials And Methods: This cross-sectional study was conducted with 83 obese women (BMI > 30 kg/m) who underwent TLH (35 patients) or vNOTES hysterectomy (48 patients) for benign gynecological indications. The duration of surgery, intra/postoperative complications, intra- and postoperative hemoglobin (Hb) and hematocrit (Hct) levels, hospital stay, Visual analogue scale (VAS) scores at the postoperative 6th and 24th hours of the patients were compared.

Introduction: Natural orifice transluminal endoscopic surgery has been used for gynecologic operations in recent years. The aim of the study is to describe our initial experience using vaginal-assisted natural orifice transluminal endoscopic surgery (vNOTES) for apical pelvic organ prolapse repair.

Methods: After patients underwent vaginal hysterectomy, vNOTES sacrocolpopexy (n = 4) or vNOTES high uterosacral ligament suspension (n = 7) were performed to treat symptomatic apical pelvic organ prolapse.

Aim: To observe the clinical course of symptomatic pregnant women diagnosed with or suspected of having COVID-19.

Methods: This study analyzed the clinical and laboratory results of 27 patients with real-time polymerase chain reaction (RT-PCR)-confirmed COVID-19 and 25 patients with a suspected COVID-19 diagnosis based on their symptoms and chest computed tomography (CT) findings. The patients' coagulation parameters and acute-phase reactants were evaluated both before and after treatment.

Introduction And Hypothesis: Cervical elongation (CE) has not been clearly defined and has similar symptoms to pelvic organ prolapse. We aimed to evaluate the diagnostic value of preoperative POP-Q examinations, ultrasonographic measurements, and direct cervical length measurement with a Foley catheter in predicting CE on postoperative hysterectomy specimens.

Methods: Fifty-six patients who underwent vaginal hysterectomy for apical pelvic organ prolapse were included.

Aim: To compare the results of conventional laparoscopic (CL) and vaginal natural orifice transluminal endoscopic surgery (vNOTES) techniques for the treatment of benign adnexal pathologies.

Materials And Methods: The study consisted of 114 patients who underwent CL or vNOTES for oophorectomy, ovarian cystectomy, or ectopic pregnancies. The medical and surgical data of the study population in terms of age, gravidity, parity, body mass index (BMI), duration of surgery, size of the mass, decrease in hemoglobin/hematocrit levels, the presence of complications, and visual analogue scale (VAS) pain scores at the 6th and 24th hours were analyzed.

Objectives: To evaluate the rates of pain and mass recurrence of the patients over 40 years old with endometriosis who underwent ovarian cystectomy or uni/bilateral oophorectomy.

Material And Methods: A retrospective study was conducted with 98 patients undergoing laparoscopic surgery for endometriosis in a tertiary referral center between the time period July 2015 and July 2019. All the patients followed every 3 months and requested to fill the Visual Analogue Scale (VAS) for evaluation of pelvic pain and an ultrasound scan was performed.

Hysterectomy is one of the most frequent gynaecological procedures performed for various uterine pathologies. There are several approaches for conducting hysterectomies, including abdominal, vaginal, laparoscopic and robotic. Recently, natural orifices transluminal endoscopic surgery (NOTES) has emerged as an alternative approach for conducting hysterectomies.

In this prospective randomised placebo-controlled study, we aimed to evaluate the effect of New Cross linked Hyaluronan Gel (NCH gel) on the quality of life of patients who underwent laparoscopic surgery due to Deep Infiltrating Endometriosis (DIE). The intervention group received 40 mL of NCH gel, and the control group had a 40 mL sterile saline solution instilled into the peritoneal cavity following standard laparoscopic procedures. The patients were called in the third and sixth postoperative months and requested to fill the Visual Analogue Scale (VAS), Endometriosis Health Profile (EHP-5), and Short Form for Mental and Physical Health (SF-12) questionnaires.
