Incidence and groups at risk for unexpected uterine leiomyosarcoma: a Dutch nationwide cohort study.

Objective: To estimate the risk of uterine leiomyosarcoma in patients undergoing gynecological surgery and also to identify groups at risk for unrecognized uterine leiomyosarcoma.

Methods: A national cohort study was performed evaluating all uterine leiomyosarcoma (ULMS) diagnosed in The Netherlands between January 2000 and September 2015. Cases were identified and supplied by the nationwide network and registry of histo- and cytopathology in The Netherlands (PALGA).

Human cadavers to evaluate prototypes of minimally invasive surgical instruments: A feasibility study.

Background: New technology should be extensively tested before it is tried on patients. Unfortunately representative models are lacking. In theory, fresh frozen human cadavers are excellent models.

Surgical flow disturbances in dedicated minimally invasive surgery suites: an observational study to assess its supposed superiority over conventional suites.

Background: Minimally invasive surgery (MIS) is frequently compromised by surgical flow disturbances due to technology- and equipment-related failures. Compared with MIS in a conventional cart-based OR, performing MIS in a dedicated integrated operating room (OR) is supposed to be beneficial to patient safety. The aim of this study was to compare a conventional OR with an integrated OR with regard to the incidence and effect of equipment-related surgical flow disturbances during an advanced laparoscopic gynecological procedure [laparoscopic hysterectomy (LH)].

Case-Mix Variables and Predictors for Outcomes of Laparoscopic Hysterectomy: A Systematic Review.

The assessment of surgical quality is complex, and an adequate case-mix correction is missing in currently applied quality indicators. The purpose of this study is to give an overview of all studies mentioning statistically significant associations between patient characteristics and surgical outcomes for laparoscopic hysterectomy (LH). Additionally, we identified a set of potential case-mix characteristics for LH.

Treatment with methotrexate of a cornual pregnancy following endometrial resection.

Objectives: Endometrial resection is a procedure often performed for treatment of menorrhagia. Despite the fact that amenorrhoea frequently ensues, some normal endometrium can remain present and become the implantation site of a pregnancy. Such an event is uncommon (0.

Measurement and significance of sperm morphology.

The measurement or evaluation and clinical significance of human sperm morphology has always been and still is a controversial aspect of the semen analysis for the determination of a male's fertility potential. In this review the background of the development of the evaluation criteria for sperm morphology will be discussed. Aspects of criticism on the strict criteria definition and use of the criteria for sperm morphology evaluation will be discussed as well as possible reasons for the decline in normal sperm morphology values and how we can compromise for this phenomenon resulting in the very low normal reference value as published in the 2010 WHO manual for the Examination and Processing of Human Semen.

[Safe introduction of laparoscopic hysterectomy using a mentor].

Objective: Evaluation of the introduction of laparoscopic hysterectomy in a teaching hospital by means of a structured mentor-traineeship.

Design: Retrospective, with prospectively designed database.

Methods: By means of a mentor-traineeship the technique of laparoscopic hysterectomy was introduced to two gynaecologists in a teaching hospital.

Secondary infertility caused by the retention of fetal bones after an abortion: a case report.

Introduction: Unwanted contraception through prolonged retention of fetal bone is a rare cause of secondary infertility. It is usually associated with a history of abortion, either spontaneous or induced.

Case Presentation: We describe a case of intrauterine retention of fetal bone diagnosed 8 years after the termination of a pregnancy.
