Extended Lichtenstein Repair for an Additional Femoral Canal Hernia.

The Lichtenstein procedure is one of the most performed surgeries worldwide. However, proper examination to exclude a femoral hernia is often not performed, resulting in a high number of missed hernias. For patients in whom a femoral hernia is suspected pre- or intraoperatively, we describe a novel surgical technique of a femoral extension to the classic Lichtenstein repair.

Pericardial fenestration and thoracic duct ligation for treatment of chylopericardium as first symptom of underlying generalized lymphatic anomaly: a case report.

Introduction: Chylopericardium represents a rare condition of chyle accumulation within the pericardial sac, caused by abnormal thoracic duct anatomy or prolonged increased pressure. Nothing by mouth (NPO) policy and total parenteral nutrition (TPN), even in combination with pericardial drainage, render only a temporary solution. Surgical intervention with thoracic duct ligation and creation of a pericardial window is believed to be the most effective treatment.

Development of pancreatic diseases during long-term follow-up after acute pancreatitis: a post-hoc analysis of a prospective multicenter cohort.

Background And Aim: More insight into the incidence of and factors associated with progression following a first episode of acute pancreatitis (AP) would offer opportunities for improvements in disease management and patient counseling.

Methods: A long-term post hoc analysis of a prospective cohort of patients with AP (2008-2015) was performed. Primary endpoints were recurrent acute pancreatitis (RAP), chronic pancreatitis (CP), and pancreatic cancer.

Prognostic model on niche development after a first caesarean section: development and internal validation.

Objective: To develop and internally validate a prognostic prediction model for development of a niche in the uterine scar after a first caesarean section (CS).

Study Design: Secondary analyses on data of a randomized controlled trial, performed in 32 hospitals in the Netherlands among women undergoing a first caesarean section. We used multivariable backward logistic regression.

Endovascular Revascularization Plus Supervised Exercise Versus Supervised Exercise Only for Intermittent Claudication: A Cost-Effectiveness Analysis.

[Figure: see text].

Diagnosis of Menière's disease on MRI: feasibility at 1.5 Tesla.

Background: Menière's disease (MD) is clinically characterized by the triad sensorineural hearing loss, tinnitus and/or aural fullness, and vertigo. Endolymphatic hydrops (EH) is the histopathological basis associated with MD, which can be demonstrated on magnetic resonance imaging (MRI). Currently, most studies are done on a 3-T MRI scanner and to date it is believed that EH can only be demonstrated on a 3-T magnet.

What is the effect of MRI with targeted biopsies on the rate of patients discontinuing active surveillance? A reflection of the use of MRI in the PRIAS study.

Background: The reduction of overtreatment by active surveillance (AS) is limited in patients with low-risk prostate cancer (PCa) due to high rates of patients switching to radical treatment. MRI improves biopsy accuracy and could therewith affect inclusion in or continuation of AS. We aim to assess the effect of MRI with target biopsies on the total rate of patients discontinuing AS, and in particular discontinuation due to Grade Group (GG) reclassification.

Factors associated with the progression of gastric intestinal metaplasia: a multicenter, prospective cohort study.

Gastric cancer (GC) is usually preceded by premalignant gastric lesions (GPLs) such as gastric intestinal metaplasia (GIM). Information on risk factors associated with neoplastic progression of GIM are scarce. This study aimed to identify predictors for progression of GIM in areas with low GC incidence.

Accuracy of upper endoscopies with random biopsies to identify patients with gastric premalignant lesions who can safely be exempt from surveillance.

Introduction: Guidelines recommend endoscopy with biopsies to stratify patients with gastric premalignant lesions (GPL) to high and low progression risk. High-risk patients are recommended to undergo surveillance. We aimed to assess the accuracy of guideline recommendations to identify low-risk patients, who can safely be discharged from surveillance.

Long-term Follow-up of a Randomized Clinical Trial Comparing Endovascular Revascularization Plus Supervised Exercise With Supervised Exercise Only for Intermittent Claudication.

Objective: The goal of this study was to assess the long-term effectiveness of combination therapy for intermittent claudication, compared with supervised exercise only.

Background: Supervised exercise therapy is recommended as first-line treatment for intermittent claudication by recent guidelines. Combining endovascular revascularization plus supervised exercise shows promising results; however, there is a lack of long-term follow-up.

Anti-Müllerian Hormone Levels in Adolescence in Relation to Long-term Follow-up for Presence of Polycystic Ovary Syndrome.

Context: Anti-Müllerian hormone (AMH) measured in adolescence as biomarker for prediction of adult polycystic ovary syndrome (PCOS) is doubtful but not substantiated.

Objective: To investigate whether serum AMH levels and other PCOS-associated features in adolescence can predict the presence of PCOS in adulthood.

Design And Setting: A long-term follow-up study based on a unique adolescent study on menstrual irregularities performed between 1990 and 1997.

Optimizing cytological specimens of EUS-FNA of solid pancreatic lesions: A pilot study to the effect of a smear preparation training for endoscopy personnel on sample quality and accuracy.

Background: In the absence of rapid on-side pathological evaluation, endoscopy staff generally "smears" endoscopic ultrasound guided fine needle aspiration (EUS-FNA) specimens on a glass slide. As this technique is vulnerable to preparation artifacts, we assessed if its quality could be improved through a smear-preparation-training for endoscopy staff.

Methods: In this prospective pilot study, 10 endosonographers and 12 endoscopy nurses from seven regional EUS-centers in the Netherlands were invited to participate in a EUS-FNA smear-preparation-training.

Diagnostic yield and agreement on fine-needle specimens from solid pancreatic lesions : comparing the smear technique to liquid-based cytology.

 The traditional "smear technique" for processing and assessing endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is sensitive to artifacts. Processing and evaluation of specimens collected in a liquid medium, liquid-based cytology (LBC) may be a solution. We compared the diagnostic value of EUS-FNA smears to LBC in pancreatic solid lesions in the absence of rapid on-site evaluation (ROSE).

Study protocol of a phase II clinical trial of oral metformin for the intravesical treatment of non-muscle invasive bladder cancer.

Background: Non-muscle-invasive bladder cancer (NMIBC) is the most common neoplasm of the urinary tract and requires life-long invasive surveillance to detect disease recurrence. Currently, there are no effective oral therapies that delay disease recurrence or progression. We recently demonstrated that in mice, metformin accumulates unchanged in the urine.

Collaboration of community hospital endosonographers improves diagnostic yield of endoscopic ultrasonography guided tissue acquisition of solid pancreatic lesions.

Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) is the method of choice for establishing a pathological diagnosis of solid pancreatic lesions. Data on quality and yield of EUS-guided TA performed in community hospitals are lacking. A study was performed to determine and improve the diagnostic yield of EUS-guided TA in a group of community hospitals.

Single- versus double-layer closure of the caesarean (uterine) scar in the prevention of gynaecological symptoms in relation to niche development - the 2Close study: a multicentre randomised controlled trial.

Background: Double-layer compared to single-layer closure of the uterus after a caesarean section (CS) leads to a thicker myometrial layer at the site of the CS scar, also called residual myometrium thickness (RMT). It possibly decreases the development of a niche, which is an interruption of the myometrium at the site of the uterine scar. Thin RMT and a niche are associated with gynaecological symptoms, obstetric complications in a subsequent pregnancy and delivery and possibly with subfertility.

Use of fosfomycin as targeted antibiotic prophylaxis before prostate biopsy: A prospective randomized study.

Objectives: To investigate whether switching ciprofloxacin to fosfomycin in the case of fluoroquinolone-resistant rectal bacteria influences the incidence of infectious complications after transrectal prostate biopsy.

Methods: From December 2015 until December 2017, patients undergoing prostate biopsy were randomly assigned to a control group or an intervention group in a prospective, open-label fashion at three different centers. The presence of fluoroquinolone-resistant organisms was detected by rectal swabs.

Surveillance of premalignant gastric lesions: a multicentre prospective cohort study from low incidence regions.

Objective: International guidelines recommend endoscopic surveillance of premalignant gastric lesions. However, the diagnostic yield and preventive effect require further study. We therefore aimed to assess the incidence of neoplastic progression and to assess the ability of various tests to identify patients most at risk for progression.

The FOAM study: is Hysterosalpingo foam sonography (HyFoSy) a cost-effective alternative for hysterosalpingography (HSG) in assessing tubal patency in subfertile women? Study protocol for a randomized controlled trial.

Background: Tubal pathology is a causative factor in 20% of subfertile couples. Traditionally, tubal testing during fertility work-up is performed by hysterosalpingography (HSG). Hysterosalpingo-foam sonography (HyFoSy) is a new technique that is thought to have comparable accuracy as HSG, while it is less expensive and more patient friendly.

Modification of the use of the extensor retinaculum for reducible distal radioulnar joint instability: technique and results.

Unlabelled: Different surgical techniques have been described for chronic distal radioulnar joint instability: they are often complicated, quite invasive and may not be recommended for bidirectional instability. We describe a procedure using a radial-based extensor retinaculum strip and a capsular plication. This is a simple technique and less invasive than 'anatomic' radioulnar ligament reconstructions.

Oil-Based or Water-Based Contrast for Hysterosalpingography in Infertile Women.

Background: Pregnancy rates among infertile women have been reported to increase after hysterosalpingography, but it is unclear whether the type of contrast medium used (oil-based or water-soluble contrast) influences this potential therapeutic effect.

Methods: We performed a multicenter, randomized trial in 27 hospitals in the Netherlands in which infertile women who were undergoing hysterosalpingography were randomly assigned to undergo this procedure with the use of oil-based or water-based contrast. Subsequently, couples received expectant management or the women underwent intrauterine insemination.

Individual duration of axillary brachial plexus block is unpredictable: a prospective double centered observational study.

Background: The duration of effect for axillary plexus block using ropivacaine is highly variable. The available literature does not offer any plausible means of predicting time of block offset for individual patients, making it difficult to give accurate information and plan postoperative analgesics. This study was designed to identify factors influencing axillary plexus block offset time.

Psoas abscess after bacille Calmette-Guérin instillations causing iliac artery contained rupture.

Intravesical administration of bacille Calmette-Guérin (BCG) is considered to be the therapy of choice for treating superficial bladder carcinoma. Created from a live attenuated strain of Mycobacterium bovis, BCG is theoretically unable to cause infections. However, both local and systemic complications due to infection are known to arise, including vascular complications.
