SamenvattingDe kosten van de gezondheidszorg stijgen. Bewustwording van daadwerkelijke kosten (in plaats van gemiddelde DBC-prijzen) is van groot belang om kosten te beteugelen. Hiertoe hebben wij voor 72 ureterorenoscopie (URS) procedures de gegevens over proceduretijd, materiaal, aanwezig personeel op OK, opname en follow-up prospectief geregistreerd. De totale kosten van een URS bedroegen gemiddeld € 2.819. De grootste kostenpost bestond uit chirurgische kosten (€ 2.075; 67,0%), gevolgd door opnamekosten (€ 514; 22,8%) en follow-upkosten (€ 230; 10,2%). Bij acht procedures bleek de steen gepasseerd ten tijde van de operatie en bleek de preoperatieve CT-scan ouder dan één maand. De kosten van deze procedures hadden voorkomen kunnen worden door een extra preoperatieve CT-scan te maken. Het verrichten van deze CT-scan zou een besparing kunnen opleveren van gemiddeld € 62 euro per procedure. De werkelijke kosten van een URS in dit cohort waren € 2.819, met als grootste kostenpost chirurgische kosten (€ 2.075). Het waarborgen van recente preoperatieve beeldvorming zou onnodige operaties en kosten kunnen besparen.

SamenvattingIn een placebogecontroleerde, multicenter, dubbelblind gerandomiseerde studie met 128 patiënten met bevestigde niersteenkolieken is onderzocht of placebo non-inferieur is aan continue infusie van butylscopolamine. De ene arm kreeg continue infusie van butylscopolamine, de andere arm placebo (zoutoplossing i.v.). De primaire uitkomstmaat was de hoeveelheid escapemedicatie in aantal toegediende doses. Het mediane aantal doses was in beide groepen één. Het aantal extra doses in de placebogroep was 0,05, met een 95% robuust BI van −0,38–0,47. De bovengrens van het BI bleef onder de gestelde non-inferioriteitsgrens van 0,5 (p = 0,04). Er werden geen verschillen gezien tussen de groepen in secundaire uitkomstmaten. Placebo is non-inferieur aan butylscopolamine continue infusie ter pijnstilling bij patiënten met een niersteenkoliek. Op basis van dit onderzoek en eerdere studies blijkt continue infusie van butylscopolamine iv niet van meerwaarde te zijn bij de behandeling van patiënten met een niersteenkoliek.

Percentage Gleason pattern 4, invasive cribriform and/or intraductal carcinoma (IC/IDC) and minor pattern 5 are recognized as independent parameters for prostate cancer outcome, but are not incorporated in current grade groups (GGs). Two proof-of-principle studies have proposed alternative grading schemes based on percentage Gleason pattern 4/5 (integrated quantitative Gleason score; IQ-Gleason) and IC/IDC presence (cribriform grade; cGrade). Our objective was to compare the performance of GG, IQ-Gleason and cGrade for predicting biochemical recurrence and metastasis after radical prostatectomy (RP). RP specimens of 1064 patients were pathologically reviewed and graded according to the three schemes. Discriminative power for prediction of biochemical recurrence-free (BCRFS) and metastasis-free (MFS) survival was compared using Harrell’s c-index. The GG distribution at RP was 207 (19.4%) GG1, 472 (44.4%) GG2, 126 (11.8%) GG3, 140 (13.2%) GG4 and 119 (11.2%) GG5. Grading according to 5-tier IQ-Gleason and cGrade systems led to categorical shifts in 49.8% and 29.7% of cases, respectively. Continuous IQ-Gleason had the best performance for predicting BCRFS (c-index 0.743, 95% confidence interval (CI) 0.715–0.771), followed by cGrade (c-index 0.738, 95%CI 0.712–0.759), 5-tier categorical IQ-Gleason (c-index 0.723, 95%CI 0.695–0.750) and GG (c-index 0.718, 95%CI 0.691–0.744). Continuous IQ-Gleason (c-index 0.834, 95%CI 0.802–0.863) and cGrade (c-index 0.834, 95%CI 0.808–0.866) both had better predictive value for MFS than categorical IQ-Gleason (c-index 0.823, 95%CI 0.788–0.857) and GG (c-index 0.806, 95%CI 0.777–0.839). In conclusion, the performance of prostate cancer grading can be improved by alternative grading schemes incorporating percent Gleason pattern 4/5 and IC/IDC.

Background Chronic anal fissure (CAF) is a common, bothersome condition frequently accompanied by pelvic floor complaints. Despite current guidelines, optimal management is challenging. The aim of this study is to evaluate current management of CAF among gastrointestinal surgeons in the Netherlands. Methods Dutch gastrointestinal surgeons and residents were sent a survey invitation by email, which was available online between June 2021 and September 2021. The questionnaire consisted of 21 questions concerning work experience, physical examination, diagnostic and surgical techniques, and follow-up. Results Overall, 106 (33%) respondents completed the survey. Most respondents (59%) had at least 10 years of experience in treating CAF. Only 23% always addressed pelvic floor complaints. Fifty-one percent performed digital rectal examination and 22% always, or almost always, examined the pelvic floor muscles. Most respondents started treatment with fibers and/or laxatives and ointment (96%). Diltiazem was in 90% the preferred ointment. Twenty-two percent referred patients for pelvic floor physical therapy. Botulinum toxin was in 54% performed under general or spinal anesthesia or sedation. The surgical procedure of choice was fissurectomy (71%) followed by lateral internal sphincterotomy (27%). Fissurectomy was in 51% always combined with botulinum toxin. Fifty-seven percent of the respondents preferred a physical follow-up appointment. Conclusion Guideline recommendations are largely followed in the Netherlands, starting with conservative measures followed by surgical procedures. Surgeons do not consistently assess pelvic floor complaints, nor do they routinely examine the pelvic floor muscles. Awareness of pelvic floor dysfunctions is important to refer patients for pelvic floor physical therapy.
