Background: Pancreatic adenocarcinoma located in the pancreatic body might require a portomesenteric venous resection (PVR), but data regarding surgical risks after distal pancreatectomy (DP) with PVR are sparse. Insight into additional surgical risks of DP-PVR could support preoperative counseling and intraoperative decision making. This study aimed to provide insight into the surgical outcome of DP-PVR, including its potential risk elevation over standard DP., Methods: We conducted a retrospective, multicenter study including all patients with pancreatic adenocarcinoma who underwent DP ± PVR (2018-2020), registered in four audits for pancreatic surgery from North America, Germany, Sweden, and The Netherlands. Patients who underwent concomitant arterial and/or multivisceral resection(s) were excluded. Predictors for in-hospital/30-day major morbidity and mortality were investigated by logistic regression, correcting for each audit., Results: Overall, 2924 patients after DP were included, of whom 241 patients (8.2%) underwent DP-PVR. Rates of major morbidity (24% vs. 18%; p = 0.024) and post-pancreatectomy hemorrhage grade B/C (10% vs. 3%; p = 0.041) were higher after DP-PVR compared with standard DP. Mortality after DP-PVR and standard DP did not differ significantly (2% vs. 1%; p = 0.542). Predictors for major morbidity were PVR (odds ratio [OR] 1.500, 95% confidence interval [CI] 1.086-2.071) and conversion from minimally invasive to open surgery (OR 1.420, 95% CI 1.032-1.970). Predictors for mortality were higher age (OR 1.087, 95% CI 1.045-1.132), chronic obstructive pulmonary disease (OR 4.167, 95% CI 1.852-9.374), and conversion from minimally invasive to open surgery (OR 2.919, 95% CI 1.197-7.118), whereas concomitant PVR was not associated with mortality., Conclusions: PVR during DP for pancreatic adenocarcinoma in the pancreatic body is associated with increased morbidity, but can be performed safely in terms of mortality., (© 2024.

Objectives Objectives of this study were to evaluate the effect of changes in patterns of care, for example centralization and treatment sequence, on surgical outcome and survival in patients with epithelial ovarian cancer (EOC). Methods Patients diagnosed with FIGO stage IIB-IV EOC (2004–2013) were selected from the Netherlands Cancer Registry. Primary outcomes were surgical outcome (extent of macroscopic residual tumor after surgery) and overall survival. Changes in treatment sequence (primary debulking surgery and adjuvant chemotherapy (PDS + ACT) or neo-adjuvant chemotherapy and interval debulking surgery (NACT + IDS)), hospital type and annual hospital volume were also evaluated. Results Patient and tumor characteristics of 7987 patients were retrieved. Most patients were diagnosed with stage III-IV EOC. The average annual case-load per hospital increased from 8 to 28. More patients received an optimal cytoreduction (tumor residue ≤ 1 cm) in 2013 (87%) compared to 2004 (55%, p < 0.001). Complete cytoreduction (no macroscopic residual tumor), registered since 2010, increased from 42% to 52% (2010 and 2013, respectively, p < 0.001). Optimal/complete cytoreduction was achieved in 85% in high volume (≥ 20 cytoreductive surgeries annually), 80% in medium (10–19 surgeries) and 71% in small hospitals (< 10 surgeries, p < 0.001). Within a selection of patients with advanced stage disease that underwent surgery the proportion of patients undergoing NACT + IDS increased from 28% (2004) to 71% (2013). Between 2004 and 2013 a 3% annual reduction in risk of death was observed (HR 0.97, p < 0.001). Conclusion Changes in pattern of care for patients with EOC in the Netherlands have led to improvement in surgical outcome and survival. [ABSTRACT FROM AUTHOR]

Abstract: Aim: To investigate the quality of surgical colorectal cancer (CRC) care in the southern Netherlands by evaluating differences between the five hospitals with the lowest volume and the five hospitals with the highest volume. Methods: Patients who underwent resection for primary CRC diagnosed between 2008 and 2011 in southern Netherlands were included (n = 5655). The five hospitals performing <130 resections/year were classified ‘low volume’; the five hospitals performing ≥130 resections/year ‘high volume’. Differences in surgical approach, circumferential resection margins (CRM), anastomotic leakage and 30-day mortality between hospital volumes were analysed using Chi2 tests. Expected proportions anastomotic leakage and 30-day mortality were calculated using multivariable logistic regression. Crude 3-year survival was calculated using Kaplan–Meier curves. Cox regression was used to discriminate independent risk factors for death. Results: 23% of patients with locally advanced rectal cancer (LARC) diagnosed in a low volume centre was referred to a high volume centre. Patients with colon cancer underwent less laparoscopic surgery and less urgent surgery in low compared to high volume hospitals (10% versus 32%, p < 0.0001, and 8% versus 11%, p = 0.003, respectively). For rectal cancer, rates of abdominoperineal resections versus low anterior resections, and CRM were not associated with hospital volume. Anastomotic leakage, 30-day mortality, and survival did not differ between hospital volumes. Conclusion: In southern Netherlands, low volume hospitals deliver similar high quality surgical CRC care as high volume hospitals in terms of CRM, anastomotic leakage and survival, also after adjustment for casemix. However, this excludes LARC since a substantial proportion was referred to high volume hospitals. [Copyright &y& Elsevier]

Background: First-choice treatment for Cushing's disease is transsphenoidal adenomectomy. Since its introduction in the 1970s, many centers have now switched from microscopic to endoscopic surgery. We compared both techniques for the treatment of Cushing's disease at the Leiden University Medical Center, a European reference center for pituitary diseases., Methods: Cohort study with inclusion and follow-up of consecutive Cushing's disease patients primarily treated by transsphenoidal surgery at the Leiden University Medical Center between 1978 and 2016. We compared remission rates (primary endpoint), mortality, and complications between microscopic (performed up to 2005) and endoscopic (performed from 2003 onwards) surgery. Subgroup analyses were performed by tumor size, surgical experience, and preoperative imaging techniques. Additionally, surgeons' intraoperative findings regarding presence and removal of the adenoma were related to surgical outcome., Results: Of 137 included patients, 87 were treated microscopically and 50 endoscopically. Three months after microscopic surgery, 74 patients (86%) were in remission. Five-year recurrence-free survival was 89% (95% confidence interval [CI]: 82-96%), and ten-year recurrence free survival was 84% (95% CI: 75-93%). After endoscopic surgery, 39 patients (83%) were in remission. Both five-year and ten-year recurrence-free survival were 71% (95% CI: 55-87%). Hazard ratio for recurrence was 0.47 (95% CI: 0.19-1.14), and for mortality 2.79 (95% CI: 0.35-22.51), for microscopic versus endoscopic surgery. No learning curve was found for endoscopy, nor an influence of preoperative imaging technique for microscopy. In addition, we did not find a clear relation between the surgeons' intraoperative findings and surgical outcomes., Conclusions: This study did not identify a clear advantage of microscopic or endoscopic transsphenoidal surgery for the treatment of Cushing's disease based on clinical outcome. The transition to endoscopic surgery at our center was not accompanied by transient worsening of outcomes, which may be reassuring for those considering transitioning.

Objectives: Failure to rescue (FTR) is a composite quality indicator, defined as the proportion of deceased patients following major complications. The aims of this study were to compare FTR with mortality for hospital comparisons in abdominal aortic aneurysm (AAA) surgery in The Netherlands and investigate hospital volume and associated factors., Methods: Patients prospectively registered between 2013 and 2015 in the Dutch Surgical Aneurysm Audit (DSAA) were analysed. FTR was analysed for AAA patients and subgroups elective (EAAA) and acute (AAAA; symptomatic or ruptured) aneurysms. Variables and hospital volume were analysed by uni- and multivariable regression analysis. Adjusted hospital comparisons for mortality, major complications, and FTR were presented in funnel plots. Isomortality lines were constructed when presenting FTR and major complication rates., Results: A total of 9258 patients were analysed in 61 hospitals: 7149 EAAA patients (77.2%) and 2109 AAAA patients (22.8%). There were 2785 (30.1%) patients with complications (unadjusted range 5-65% per hospital): 2161 (77.6%) with major and 624 (28.4%) patients with minor complications. Overall mortality was 6.6% (adjusted range 0-16% per hospital) and FTR was 28.4% (n = 613) (adjusted range 0-60% per hospital). Glasgow Coma Scale, age, pulse, creatinine, electrocardiography, and operative setting were independently associated with FTR. Hospital volume was not associated with FTR. In AAAA patients hospital volume was significantly associated with a lower adjusted major complication and mortality rate (OR 0.62, 95% CI 0.49-0.78; and 0.64, 95% CI 0.48-0.87). Four hospitals had a significant lower adjusted FTR with different major complication rates on different isomortality lines., Conclusions: There was more variation in FTR than in mortality between hospitals. FTR identified the same best performing hospitals as for mortality and therefore was of limited additional value in measuring quality of care for AAA surgery. FTR can be used for internal quality improvement with major complications in funnel plots and diagrams with isomortality lines., (Copyright © 2018 European Society for Vascular Surgery.
