Effectiveness of Mechanical Bowel Preparation before Robot-Assisted Laparoscopic Gynecologic Surgery: A Randomized, Single-Blind, Controlled Trial.

Objective: The objective of this randomized controlled trial was to compare the effect of bowel preparation using only oral polyethylene glycol electrolyte (PEG) solution versus oral PEG solution combined with mechanical sodium phosphate (NaP) enema on the surgical field visualization in patients undergoing robot-assisted laparoscopic gynecologic procedures.

Methods: Participants were randomized to either a single oral PEG solution or an oral PEG solution combined by mechanical NaP enema. The intraoperative visualization of the surgical field, the ease of manipulation of the bowels, and overall difficulty level of the surgery were evaluated by the surgeon using a self-administered questionnaire.

Comparison of the Right and Left Femur Bone Mineral Densities in Postmenopausal Women.

Objectives: Bone mineral density (BMD) is measured in the hip and posteroanterior spine; moreover, according to the 2019 International Society for Clinical Densitometry guidelines, unilateral hip can be used. This study aimed to determine whether there is a difference between the BMD of both the femurs in postmenopausal women.

Methods: A total of 343 postmenopausal women were enrolled in this study from January 1, 2010, to December 31, 2019 at a single tertiary hospital.

The Estimated Prevalence and Incidence of Endometriosis With the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC): A National Population-Based Study.

Background: The incidence and prevalence of endometriosis remain unclear due to diagnostic difficulties. Especially, there has been little information regarding the population-based epidemiology of endometriosis. The purpose of this study is to estimate the prevalence and incidence of endometriosis in Korea based on the health insurance claims data.
